[0002] Circumcision is one of the most common surgeries in urology, and doctors can use surgical instruments to cut the foreskin. The surgical instruments in the prior art have a large degree of obstruction to the surgical operation field of the doctor, the operable field of view of the doctor is small, and the doctor cannot accurately adjust the relative position between the surgical instrument and the foreskin, that is, the doctor cannot adjust the length of the foreskin to be reserved under direct vision, resulting in poor surgical precision. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a surgical instrument, which can be used by the doctor to adjust the relative position between the surgical instrument and the surgical object under direct vision, thereby improving the precision of the surgery.

[0004] The present application provides a surgical instrument, which comprises a first operating member, a second operating member and a driving member, at least one of the first operating member and the second operating member is used to be sleeved on an organ, and the surgical instrument comprises at least a first state and a second state. In the first state, the first operating member is separated from the second operating member, and in the second state, the first operating member and the second operating member are both connected to the driving member, so that the driving member can drive the at least partial structure of the first operating member and the at least partial structure of the second operating member to move towards each other.

[0005] In the surgical process, the user can first make the surgical instrument in the first state. The user can first operate any one of the first operating member and the second operating member to be sleeved on the organ. Taking the first operating member sleeved on the organ as an example, the user can sleeve the first operating member on the organ and adjust the position of the first operating member relative to the organ. Similarly, taking the second operating member sleeved on the organ as an example, the user can sleeve the second operating member on the organ and adjust the position of the second operating member relative to the organ. If the user first sleeves the first operating member on the organ, the user's hand can also temporarily fix the part of the organ to be medically operated on the first operating member which has been sleeved on the organ. Similarly, if the user first sleeves the second operating member on the organ, the user's hand can also temporarily fix the part of the organ to be medically operated on the second operating member which has been sleeved on the organ. After the above operation process is completed, the user can make the surgical instrument in the second state, that is, the first operating member is connected to the driving member and the second operating member is connected to the driving member. The user can drive the at least partial structure of the first operating member and the at least partial structure of the second operating member to move towards each other by operating the driving member, so as to complete the medical operation on the organ by the first operating member and the second operating member.

[0006] As for the prior art surgical instrument, during the surgery, the user needs to set the overall structure of the prior art surgical instrument on the organ and then adjust the organ and the prior art surgical instrument, but the overall structure of the prior art surgical instrument has a large shielding area for the organ, so that the user has a small operable field of view, and the overall structure of the prior art surgical instrument also has a large volume, so that the user has a small operable range of the hand, and it is difficult for the user to accurately adjust the relative position between the part of the organ to be medically operated and the prior art surgical instrument, so that the surgery precision and safety degree are poor.

[0007] As for the surgical instrument provided in the embodiments of the present application, since the first operating member and the second operating member are separated in the first state, taking the first operating member that is first set on the organ as an example, the user has a small degree of influence from the second operating member during the operation of the part of the organ to be medically operated and the first operating member, in detail, the part of the organ to be medically operated is not easily shielded and interfered by the second operating member. The user can have a large range of operable field of view, and the user's hand can also have a large operable range, so that the user can accurately adjust the relative position between the part of the organ to be medically operated and the first operating member, and the position of the structure (the driving member or the second operating member) in the surgical instrument that has a preset connection relationship with the first operating member relative to the organ is also determined accordingly. Therefore, the user has high precision in performing the surgery on the organ using the surgical instrument, and the safety degree of the surgery can be improved.

[0008] Similarly, since the first operating member and the second operating member are separated in the first state, taking the second operating member that is first set on the organ as an example, the user has a small degree of influence from the first operating member during the operation of the part of the organ to be medically operated and the second operating member, in detail, the part of the organ to be medically operated is not easily shielded and interfered by the first operating member. The user can have a large range of operable field of view, and the user's hand can also have a large operable range, so that the user can accurately adjust the relative position between the part of the organ to be medically operated and the second operating member, and the position of the structure (the driving member or the first operating member) in the surgical instrument that has a preset connection relationship with the second operating member relative to the organ is also determined accordingly. Therefore, the user has high precision in performing the medical operation on the organ using the surgical instrument, and the safety degree of the surgery can be improved.

[0009] Further, since the first operation member and the second operation member are separated in the first state, the user can separately operate the first operation member and the second operation member. The weight and the volume of the first operation member are smaller than those of the whole structure of the surgical instrument, and the weight and the volume of the second operation member are also smaller. When the user operates the first operation member in the first state, the user's hand has a smaller weight-bearing feeling and a smaller operation difficulty. Similarly, when the user operates the second operation member in the first state, the user's hand also has a smaller weight-bearing feeling and a smaller operation difficulty.

[0171] The embodiments of the present application provide a surgical instrument, which can be applied to the technical field of medical surgical instruments. A user (for example, medical personnel) can operate the surgical instrument of the embodiments of the present application to perform medical operations on organs of a used object (for example, a biological body or a patient with a disease). The organs include esophagus, stomach, intestine, urinary tract, blood vessels, limbs, fingers, penises and the like of the biological body, and the medical operations that can be completed by the surgical instrument of the embodiments of the present application include cutting, resection, scraping, suturing, clamping, hemostasis, freezing or heating and the like.

[0172] Please refer to Figure 1 The surgical instrument 10 of the embodiments of the present application includes a first operating member 1, a second operating member 2 and a driving member 3. Please refer to Figures 2-3 At least one of the first operating member 1 and the second operating member 2 is used to be sleeved on the organ 20. The surgical instrument 10 at least includes a first state (as shown in Figure 1 ) and a second state (as shown in Figure 3 ), in the first state, the first operating member 1 is separated from the second operating member 2 (no connection relationship), in the second state, the first operating member 1 and the second operating member 2 are both connected to the driving member 3, so that the driving member 3 can drive the at least partial structure of the first operating member 1 and the at least partial structure of the second operating member 2 to move towards each other (the movement towards each other is the movement of the at least partial structure of the first operating member 1 and the at least partial structure of the second operating member 2 moving towards each other, and the movement direction is parallel to the direction X).

[0173] The arrangement of at least one of the first operating element 1 and the second operating element 2 for fitting onto the organ 20 includes three fitting embodiments. First embodiment: the first operating element 1 is used for fitting onto the organ 20, while the first operating element 2 is not used for fitting onto the organ 20; Second embodiment: the first operating element 1 is not used for fitting onto the organ 20, while the second operating element 2 is used for fitting onto the organ 20; Third embodiment: as... Figure 3 As shown, both the first operating element 1 and the second operating element 2 are used to be fitted onto the organ 20. The user can choose one of the three fitting embodiments described above based on the actual surgical situation. The following content will mainly focus on... Figure 3 The first operating element 1 and the second operating element 2 shown are both used to be fitted onto the organ 20, as an example for description.

[0174] Furthermore, in the first state, the first operating element 1 and the second operating element 2 are separated, meaning there is no direct connection between the first operating element 1 and the second operating element 2, nor is there an indirect connection through other parts. This structural arrangement includes three embodiments. The first embodiment: as follows... Figure 1 As shown in the diagram, in the first embodiment, the first operating element 1 is not connected to the driving element 3, while the second operating element 2 is connected to the driving element 3; in the second embodiment, the first operating element 1 is not connected to the driving element 3, and the second operating element 2 is also not connected to the driving element 3; in the third embodiment, the first operating element 1 is connected to the driving element 3, while the second operating element 2 is not connected to the driving element 3. The following content will mainly focus on the following... Figure 1 The first state of the surgical instrument 10 is described using the example of the first operating element 1 being unconnected to the driving element 3 and the second operating element 2 being connected to the driving element 3.

[0175] Please refer to Figure 1 As shown, during the surgery, the user can first position the surgical instrument 10 in the first state. The user can then operate either the first operating element 1 or the second operating element 2, which is then fitted onto the organ 20. Please refer to... Figure 2 As shown, taking the first operating element 1, which is first fitted onto the organ 20, as an example, the user can fit the first operating element 1 onto the organ 20 and adjust its position relative to the organ 20. Similarly, taking the second operating element 2, which is first fitted onto the organ 20, as an example, the user can fit the second operating element 2 onto the organ 20 and adjust its position relative to the organ 20. Figure 2 As shown, if the user first places the first operating piece 1 on the organ 20, the user's hand can temporarily fix the part of the organ 20 to be operated on to the first operating piece 1 that has already been placed on the organ 20. Similarly, if the user first places the second operating piece 2 on the organ 20, the user's hand can temporarily fix the part of the organ 20 to be operated on to the second operating piece 2 that has already been placed on the organ 20. After completing the above operation process, the user can position the surgical instrument 10 as follows: Figure 3The second state shown is that the first operation member 1 is connected with the driving member 3 and the second operation member 2 is connected with the driving member 3. As shown in the figure Figure 4 As shown, the user can drive the first operation member 1 and the second operation member 2 to complete the medical operation on the organ 20 by operating the driving member 3 to drive the at least partial structure of the first operation member 1 and the at least partial structure of the second operation member 2 to move towards each other (the movement direction is parallel to the direction X), so that the first operation member 1 and the second operation member 2 complete the medical operation on the organ 20. Figure 5 The state shown is as shown in the figure Figure 4 The next state of the state shown is that the driving member 3 is automatically separated from the first operation member 1 after the user releases the driving member 3 or operates the driving member 3 to reset, and the content of the state shown will be described in detail later. Figure 5 The state shown is as shown in the figure

[0176] Regarding the surgical instrument of the prior art, during the operation, the user needs to set the overall structure of the surgical instrument of the prior art on the organ and then adjust the organ and the surgical instrument of the prior art, but the overall structure of the surgical instrument of the prior art has a large shielding area on the organ, which causes the user to have a small operable field of view, and the overall structure of the surgical instrument of the prior art also has a large volume, which causes the user to have a small operable range of the hand, and it is difficult for the user to accurately adjust the relative position between the part to be medically operated in the organ and the surgical instrument of the prior art, which causes the operation precision and safety degree to be poor.

[0177] Regarding the surgical instrument 10 provided by the embodiment of the present application, since the first operation member 1 is separated from the second operation member 2 in the first state, taking the first operation member 1 set on the organ 20 first as an example, the user is less affected by the second operation member 2 in the process of operating the part to be medically operated in the organ 20 and the first operation member 1, in detail, the part to be medically operated in the organ 20 is not easily shielded and interfered by the second operation member 2. The user can have a large range of operable field of view, and the user's hand can also have a large operable range, and the user can accurately adjust the relative position between the part to be medically operated in the organ 20 and the first operation member 1, and the position of the structure (driving member 3 or second operation member 2) in the surgical instrument 10 having a preset connection relationship with the first operation member 1 relative to the organ 20 is also determined accordingly. Therefore, the user can improve the precision of the operation on the organ 20 using the surgical instrument 10, and can improve the safety degree of the operation.

[0178] Similarly, since the first operation member 1 is separated from the second operation member 2 in the first state, taking the second operation member 2 as an example which is sleeved on the organ 20 first, the user is less affected by the first operation member 1 in the process of operating the part of the organ 20 to be operated and the second operation member 2, in detail, the part of the organ 20 to be operated is not easily blocked and interfered by the first operation member 1. The user can have a larger range of operable field of view, the user's hand can also have a larger range of operation, the user can accurately adjust the relative position between the part of the organ 20 to be operated and the second operation member 2, and the position of the structure (the driving member 3 or the first operation member 1) in the surgical instrument 10 which has a preset connection relationship with the second operation member 2 relative to the organ 20 is also determined accordingly. Therefore, the user can perform medical operation on the organ 20 with the surgical instrument 10 with higher precision, which can improve the safety of the operation.

[0179] Further, since the first operation member 1 is separated from the second operation member 2 in the first state, the user can operate the first operation member 1 and the second operation member 2 separately. Compared with the overall structure of the surgical instrument 10, the weight and volume of the first operation member 1 are smaller, and the weight and volume of the second operation member 2 are also smaller. When the user operates the first operation member 1 in the first state, the user's hand feels less heavy, and the corresponding operation difficulty is smaller. Similarly, when the user operates the second operation member 2 in the first state, the user's hand also feels less heavy, and the corresponding operation difficulty is also smaller.

[0180] Wherein, the sleeving order of the first operation member 1 and the second operation member 2 mainly depends on the respective structures of the first operation member 1, the second operation member 2, the driving member 3 and the organ 20 and the assembly structure therebetween, and the user can select to sleeve the first operation member 1 or the second operation member 2 on the organ 20 according to the actual situation. The subsequent content of this paper mainly takes the first operation member 1 as an example to describe.

[0181] Secondly, at least one of the first operation member 1 and the second operation member 2 can be a component for performing medical operation on the organ 20 by using non-mechanical energy, such as electrical energy, magnetic energy, electromagnetic energy, chemical energy, thermal energy or optical energy; at least one of the first operation member 1 and the second operation member 2 can also be a component for performing medical operation on the organ 20 by using mechanical energy. The subsequent content of this paper mainly takes the first operation member 1 and the second operation member 2 as an example to describe the medical operation on the organ 20 by using mechanical energy.

[0182] Furthermore, during the process of the driving member 3 driving at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 to move towards each other, at least one of the first operating member 1 and the second operating member 2 can perform medical operations on the organ 20; or, after the driving member 3 drives at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 to move towards each other, at least one of the first operating member 1 and the second operating member 2 can perform medical operations on the organ 20. The following content mainly describes the example of "during the process of the driving member 3 driving at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 to move towards each other, at least one of the first operating member 1 and the second operating member 2 can perform medical operations on the organ 20". From the above, it can be seen that the driving member 3 serves as a component for triggering the surgical instrument 10 to perform medical operations. The user's hand can directly operate the driving member 3, or the user's hand can indirectly operate the driving member 3 through other devices. The following content mainly describes the example of the user's hand directly operating the driving member 3.

[0183] Furthermore, please refer to Figures 6-7 As shown, organ 20 may include a main body 201 and surface tissue 202 covering the main body 201. Surgical instrument 10 can perform medical operations on the main body 201 and / or surface tissue 202. The following description primarily uses the penis as an example to illustrate organ 20; that is, the main body 201 can be the penile body (e.g., penile muscles, corpora cavernosa, or glans), and the surface tissue 202 can be the skin covering the penile body (e.g., foreskin). The following description primarily uses the example of surgical instrument 10 cutting the foreskin covering the glans. Accordingly, the first operating element 1 is fitted onto the portion of the main body 201 covered by the surface tissue 202 or the unexposed portion of the main body 201, such as the penile muscles or corpora cavernosa; the second operating element 2 is fitted onto the portion of the main body 201 not covered by the surface tissue 202 or the exposed portion of the main body 201, such as the glans.

[0184] The driving component 3 can be a single-bar structure, a connecting rod structure, a block structure, a shaft structure, or a column structure. This paper will primarily use a connecting rod structure as an example to describe the driving component 3.

[0185] Alternatively, please refer to Figure 8 As shown, if the driving component 3 includes a linkage structure, the driving component 3 includes a transmission section 31 and a driving section 32. The transmission section 31 and the driving section 32 are movably connected. The transmission section 31 is detachably connected to the first operating component 1, and the driving section 32 is movably connected to the second operating component 2.

[0186] In the second state, the user's hand can operate the driving section 32 to move the driving section 32 relative to the second operating member 2, the driving section 32 can drive the transmission section 31 to move at least part of the structure of the first operating member 1 towards the second operating member 2. Since the driving member 3 comprises the linkage structure, the driving member 3 has the function of force transmission, i.e. the user's hand can operate the driving member 3 at a position having a distance from the organ 20 to complete the medical operation, in this arrangement, the user's hand is difficult to block the organ 20, so that the user can perform the medical operation under the condition of directly viewing the organ 20, the surgical precision and safety level are higher. Secondly, since the driving member 3 comprises the linkage structure, the length of the driving member 3 can be selectively set, so that the user's hand can flexibly operate the surgical instrument 10 at a position having a larger activity space (for example, the space between the two lower limbs of the patient), the user's experience is higher. Furthermore, since the driving member 3 comprises the linkage structure, the connection position between the driving member 3 and the first operating member 1 can be set to a position which is not easy to block the organ 20, and similarly, the connection position between the driving member 3 and the second operating member 2 can also be set to a position which is not easy to block the organ 20, the user can accurately perform the medical operation through a larger range of vision. Further, since the driving member 3 comprises the linkage structure, the driving member 3 can have the function of converting the force size, i.e. the driving member 3 can have the effect of saving effort, so that the user can operate the driving member 3 by exerting a smaller force, thereby moving at least part of the structure of the first operating member 1 and at least part of the structure of the second operating member 2 towards each other, the user's operation strength is smaller, and the user's experience is higher.

[0187] The movable connection between the transmission section 31 and the drive section 32 can be a rotational connection and / or a sliding connection, allowing for selective configuration of the connection method according to different users' hand operating habits. The detachable connection between the transmission section 31 and the first operating member 1 facilitates the separation of the first operating member 1 from the drive member 3; that is, the user can first place the first operating member 1 onto the organ 20. The related technical effects have been described above and will not be repeated here. The detachable connection between the transmission section 31 and the first operating member 1 can be a snap-fit ​​and / or abutment (i.e., the transmission section 31 abuts against the first operating member 1 so that the transmission section 31 can push at least a portion of the structure of the first operating member 1 towards the second operating member 2), thereby allowing for relatively quick assembly and disassembly of the transmission section 31 and the first operating member 1. The movable connection between the drive section 32 and the second operating member 2 can be a rotational connection and / or a sliding connection, allowing for selective configuration of the connection method according to different users' hand operating habits. The following content mainly describes the rotational connection between the drive section 32 and the second operating member 2, as well as the rotational and sliding connection between the transmission section 31 and the drive section 32. In this setting, the drive section 32 will rotate relative to the second operating member 2 at a fixed axis, while the transmission section 31 will swing relative to the drive section 32 (a combination of rotation and sliding motion).

[0188] Secondly, please refer to Figure 9 As shown, the transmission section 31 includes a first inner rod 31a and a first outer shell 31b connected together, with the first outer shell 31b partially surrounding the first inner rod 31a; the drive section 32 includes a second inner rod 32a and a second outer shell 32b connected together, with the second outer shell 32b partially surrounding the second inner rod 32a; the first inner rod 31a and the second inner rod 32a are movably connected (rotatable connection and / or sliding connection). In actual use, the user's hand mainly contacts the first outer shell 31b and the second outer shell 32b. The material of the first inner rod 31a can be carbon fiber or plastic, and the material of the second inner rod 32b can also be carbon fiber or plastic. This arrangement can reduce the weight of the drive component 3, reduce the burden on the user's hand, and improve the user experience. The material of the first outer shell 31b can be metal, which can protect the first inner rod 31a and reduce the possibility of bending deformation or breakage; the material of the second outer shell 32b can also be metal, which can protect the second inner rod 32a and reduce the possibility of bending deformation or breakage.

[0189] Additionally, the first inner rod 31a and the first outer shell 31b can be snapped together, or they can be connected by a pin or screw. If the first inner rod 31a and the first outer shell 31b are snapped together, the first inner rod 31a may be provided with a third notch 313, and the surface of the first inner rod 31a used to enclose and form the third notch 313 can engage with a protruding structure or hook of the first outer shell 31b. Similarly, the second inner rod 32a and the second outer shell 32b can be snapped together, or they can be connected by a pin or screw. If the second inner rod 32a and the second outer shell 32b are engaged, the second inner rod 32a may be provided with a third hollow groove 323 and a fourth notch 324. The surface of the second inner rod 32a used to enclose and form the third hollow groove 323 may engage with the protruding structure or hook of the second outer shell 32b, and the surface of the second inner rod 32a used to enclose and form the fourth notch 324 may engage with another protruding structure or another hook of the second outer shell 32b.

[0190] Furthermore, the first inner rod 31a is hook-shaped.

[0191] Alternatively, please refer to Figure 10 As shown, the transmission section 31 includes a first connecting shaft 31c, and the drive section 32 is provided with a first hollow groove 321, through which the first connecting shaft 31c passes.

[0192] The first hollowed-out groove 321 in the drive section 32 is passed through the first connecting shaft 31c of the transmission section 31. The surface of the drive section 32 used to enclose the first hollowed-out groove 321 can abut against the curved sidewall of the first connecting shaft 31c. When the drive section 32 moves relative to the second operating member 2, the drive section 32 can drive the transmission section 31. At the same time, the first connecting shaft 31c can slide and rotate relative to the first hollowed-out groove 321. With this configuration, the connection structure between the transmission section 31 and the drive section 32 has more degrees of freedom of movement, which can reduce the possibility of jamming during the movement of the transmission section 31 and the drive section 32. The drive member 3 can reliably drive the first operating member 1 and the second operating member 2 to move towards each other, that is, the working reliability of the surgical instrument 10 is high.

[0193] The first hollow groove 321 can be straight, arc-shaped, U-shaped, or S-shaped. The following description will primarily use a straight groove as an example. If the first hollow groove 321 is straight, the direction in which the first operating member 1 moves towards the second operating member 2 intersects with the extension direction of the first hollow groove 321 to accommodate the movement process of the transmission segment 31 described above. This embodiment does not limit the angle between the direction in which the first operating member 1 moves towards the second operating member 2 and the extension direction of the first hollow groove 321.

[0194] Additionally, please refer to Figure 10As shown, the first hollow groove 321 may have a first end 3211 and a second end 3212 that are arranged opposite to each other. When the user operates the driving member 3 to drive at least a part of the structure of the first operating member 1 and at least a part of the structure of the second operating member 2 to move towards each other, the first connecting shaft 31c moves relative to the first hollow groove 321 in the direction from the first end 3211 to the second end 3212.

[0195] Furthermore, please refer to Figure 11 As shown, the first inner rod 31a includes two spaced-apart connecting plates 311, with a first gap space 314 between them. Each connecting plate 311 has a third connecting hole 311b. The second inner rod 32a has a first slot 321 located within the first gap space 314 between the two spaced-apart connecting plates 311, allowing the first connecting shaft 31c to pass through the third connecting hole 311b and the third slot 323, thus connecting the first inner rod 31a, the first connecting shaft 31c, and the second inner rod 32a. The two spaced-apart connecting plates 311 restrict the second inner rod 32a from moving axially along the first connecting shaft 31c. The first connecting shaft 31c and the third connecting hole 311b can be interference-fitted, reducing the likelihood of separation between the first connecting shaft 31c and the first inner rod 31a.

[0196] In other embodiments (not shown in the figure), the transmission section 31 may be provided with a first hollow groove 321, and the drive section 32 may include a first connecting shaft 31c, which passes through the first hollow groove 321. This embodiment may also have the effect of reducing the possibility of jamming of the transmission section 31 and the drive section 32 during movement, as described above, which will not be repeated here.

[0197] Alternatively, please refer to Figure 9 As shown, the driving component 3 also includes a first elastic element 33, and the driving segment 32 is also connected to the transmission segment 31 through the first elastic element 33; the surgical instrument 10 also includes, as shown in the figure, Figure 5 In the third state shown, the rebound force of the first elastic element 33 can drive the transmission section 31 to separate from the first operating element 1.

[0198] When the user operates the drive unit 3 to drive at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 to move towards each other, the relative position between the transmission section 31 and the drive section 32 changes, causing the first elastic member 33 connected to the transmission section 31 and the drive section 32 to undergo elastic deformation, accumulating elastic potential energy. After the user operates the drive unit 3 to drive at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 to a set position to complete the required medical operation (e.g., circumcision), the user can operate the drive unit 3 to reset or release the drive unit 3, so that the drive section 32 is no longer used to apply a force to the transmission section 31 to drive at least a portion of the structure of the first operating member 1 to move towards the second operating member 2, or the direction of the force is changed, or the force value is reduced. At the same time, the first elastic member 33 releases its elastic potential energy, and the rebound force of the first elastic member 33 can cause the transmission section 31 to separate from the first operating member 1, that is, the user can no longer operate the drive unit 3 to drive at least a portion of the structure of the first operating member 1 to move towards the second operating member 2. The above settings can reduce the likelihood of unnecessary procedures (such as secondary circumcision) caused by the user's poor operating habits, thereby reducing the possibility of medical accidents.

[0199] In the third state, when the first elastic element 33 drives the transmission section 31 to separate from the first operating element 1, the first connecting shaft 31c of the transmission section 31 moves relative to the first hollow groove 321 in the direction from the second end 3212 to the first end 3211.

[0200] In addition, one end of the first elastic member 33 is connected to the first inner rod 31a, and the other end of the first elastic member 33 is connected to the second inner rod 32a.

[0201] Alternatively, please refer to Figure 10 As shown, the first elastic element 33 is strip-shaped and includes a first curved sidewall 331. The transmission section 31 includes a second curved sidewall 311a. The first curved sidewall 331 surrounds and abuts against the second curved sidewall 311a.

[0202] The first elastic element 33 is strip-shaped. In the second state, the first elastic element 33 can undergo elastic deformation to easily accumulate elastic potential energy. In the third state, the first elastic element 33 applies a force to the transmission section 31 to separate the transmission section 31 from the first operating member 1. Since the first curved sidewall 331 of the first elastic element 33 surrounds and abuts against the second curved sidewall 311a of the transmission section 31, the first curved sidewall 331 can apply a force tangential to the second curved sidewall 311a, causing the transmission section 31 to have a tendency to rotate relative to it, thereby rotating the transmission section 31 to a position where it can be easily separated from the first operating member 1. The first curved sidewall 331 and the second curved sidewall 311a slide relative to each other, and the position and direction of the force between the first curved sidewall 331 and the second curved sidewall 311a change, adjusting the force to one that easily separates the transmission section 31 from the first operating member 1. Secondly, the first curved sidewall 331 and the second curved sidewall 311a are in surface contact, with a large contact area, which can reliably transmit the force.

[0203] The second curved sidewall 311a is the curved sidewall of the connecting plate 311, and the connecting plate 311 is also connected to the first connecting shaft 31c. That is, the second curved sidewall 311a is relatively close to the first connecting shaft 31c. Under this setting, the first elastic element 33 can easily drive the first connecting shaft 31c to move relative to the first hollow groove 321 in the direction from the second end 3212 to the first end 3211.

[0204] Alternatively, the first elastic element 33 can be a metal strip, and the end of the first elastic element 33 away from the first curved sidewall 331 can be welded to the second inner rod 32a. The first elastic element 33 can also be a plastic strip, and the end of the first elastic element 33 away from the first curved sidewall 331 can be bonded or fused to the second inner rod 32a.

[0205] In other embodiments (not shown in the figures), the first elastic element 33 may also be an elastic part such as a torsion spring or a spring.

[0206] Alternatively, please refer to Figures 10-11 As shown, the transmission section 31 includes a connector 312. Please refer to... Figure 12As shown, the first operating member 1 is provided with a first recess 1131. In the first state, the insertion part 312 is located outside the first recess 1131, so that the transmission section 31 is separated from the first operating member 1. In this configuration, the first operating member 1 can be first fitted onto the organ 20 by the user and the relative position between the first operating member 1 and the organ 20 can be adjusted. The influence of the second operating member 2 and the driving member 3 is relatively small. The relevant technical effects have been described above and will not be repeated here. In the second state, the insertion part 312 is inserted into the first recess 1131, so that the transmission section 31 is connected to the first operating member 1, thereby allowing the transmission section 31 to drive at least a part of the structure of the first operating member 1 to move toward the second operating member 2. The assembly relationship between the insertion part 312 and the first recess 1131 can achieve the effect of quick assembly or disassembly of the first operating member 1 and the transmission section 31. In the third state, the first elastic member 33 can drive the insertion part 312 of the transmission section 31 to quickly disengage from the first recess 1131 of the first operating member 1, so that the first operating member 1 and the transmission section 31 can be quickly separated, thereby achieving the above-mentioned effect of reducing the possibility of unnecessary operations (such as secondary circumcision) caused by the user's bad operating habits.

[0207] The first inner rod 31a includes a plug-in portion 312. In the second state, the opening of the first recess 1131 is oriented in a direction away from the second operating member 2. When the plug-in portion 312 moves into the first recess 1131, it can push at least a portion of the structure of the first operating member 1 toward the second operating member 2. When the plug-in portion 312 moves outward from the first recess 1131, it separates from the first operating member 1.

[0208] In other embodiments (not shown in the figure), the transmission segment 31 may be provided with a first recess 1131, and the first operating member 1 may include a plug-in portion 312. This embodiment can also achieve the effect of quickly assembling or disassembling the first operating member 1 and the transmission segment 31.

[0209] The following content mainly describes the transmission section 31, which includes the insertion part 312, and the first operating member 1, which is provided with the first recessed part 1131, as an example.

[0210] When the user inserts the connector 312 into the first recess 1131, the transmission segment 31 needs to overcome the elastic force of the first elastic member 33 so that the first connecting shaft 31c moves relative to the first hollowed-out groove 321 in a direction from the first end 3211 to the second end 3212. During the process of the connector 312 being inserted into the first recess 1131 and at least a portion of the structure of the first operating member 1 moving towards the second operating member 2, the combined force formed by the force of the first operating member 1 on the transmission segment 31, the force of the driving segment 32 on the transmission segment 31, and the force of the first elastic member 33 on the transmission segment 31 makes it difficult for the transmission segment 31 to disengage from the first recess 1131, so that the driving member 3 can reliably drive at least a portion of the structure of the first operating member 1 to move towards the second operating member 2. During the process of the user releasing the drive component 3, the combined force formed by the force exerted by the first operating component 1 on the transmission section 31, the force exerted by the drive section 32 on the transmission section 31, and the force exerted by the first elastic component 33 on the transmission section 31 makes it easy for the transmission section 31 to detach from the first recess 1131. This can reduce the possibility of unnecessary operations (such as secondary circumcision) due to the user's bad operating habits, thereby reducing the possibility of medical accidents.

[0211] Optionally, since the driving member 3 includes a linkage structure, the transmission section 31 can swing relative to the driving section 32, and correspondingly, the insertion part 312 can swing relative to the first recess 1131. Since at least a portion of the surface of the insertion part 312 is an arc surface (fourth curved sidewall 312b), and at least a portion of the surface of the structure used to enclose and form the first recess 1131 is also an arc surface (third curved sidewall 1131a), in the second state, these two arc surfaces can abut against each other. This arc surface abutment arrangement facilitates the smoother swing of the insertion part 312 relative to the first recess 1131, reducing the possibility of motion jamming between the transmission section 31 and the first operating member 1.

[0212] Alternatively, please refer to Figure 12 As shown, the first recess 1131 is perpendicular to the recess direction of the first recess 1131 (as shown in the figure). Figure 12 The area of ​​the cross section (parallel to the dotted line γ) increases from the inside to the outside of the first recess 1131. With this arrangement, space can be formed for the insertion part 312 to swing relative to the first recess 1131, reducing the possibility of motion jamming between the transmission section 31 and the first operating member 1.

[0213] Alternatively, please refer to Figure 12As shown, the recessed direction of the first recess 1131 and the direction in which the first operating member 1 moves towards the second operating member 2 have a set angle α, satisfying 5°≤α≤30°. Specifically, the angle α can be 5°, 10°, 15°, 20°, 25°, or 30°. This angle α allows the insertion part 312 in the third state to more easily detach from the first recess 1131 under external force (e.g., the elastic force of the first elastic member 33), thus making it easier to separate the transmission section 31 from the first operating member 1. This more easily achieves the effect of reducing the possibility of unnecessary operations (e.g., secondary foreskin cutting) due to poor user operating habits, which will not be elaborated further here.

[0214] Alternatively, please refer to Figure 10 As shown, the driving component 3 also includes a second connecting shaft 34, and the driving segment 32 is provided with a first connecting hole 322. Please refer to... Figure 13 As shown, the second operating member 2 is provided with a second connecting hole 2211. The second connecting shaft 34 passes through the first connecting hole 322 and the second connecting hole 2211, so that the driving section 32 is rotatably connected to the second operating member 2.

[0215] The second connecting shaft 34 is interference-fitted with the first connecting hole 322, and the second connecting shaft 34 is clearance-fitted with the second connecting hole 2211; alternatively, the second connecting shaft 34 is clearance-fitted with the first connecting hole 322, and the second connecting shaft 34 is interference-fitted with the second connecting hole 2211.

[0216] Alternatively, please refer to Figure 10 As shown, the surgical instrument 10 also includes a second elastic element 35. The drive segment 32 is connected to the second operating element 2 via the second elastic element 35. In the second state, when the drive element 3 drives at least a portion of the structure of the first operating element 1 and at least a portion of the structure of the second operating element 2 to move towards each other, the drive segment 32 rotates relative to the second operating element 2. The drive segment 32 and the second operating element 2 cause the second elastic element 35 to undergo elastic deformation, and the second elastic element 35 accumulates elastic potential energy. When the user operates the drive segment 32, the user's hand can feel the elastic force of the second elastic element 35 on the drive segment 32. The user can adjust the control force of the hand on the drive segment 32 according to the magnitude of the felt force, and the hand can operate the drive segment 32 smoothly so that the first operating element 1 and the second operating element 2 can move towards each other smoothly, that is, the controllability of the surgical instrument 10 is high.

[0217] When the user releases the drive segment 32, the second elastic element 35 releases its elastic potential energy to reset the drive segment 32 relative to the second operating element 2. During the reset process of the drive segment 32, the transmission segment 31 also disengages from the first recess 1131 to reduce the possibility of unnecessary operations (such as secondary foreskin cutting) due to the user's poor operating habits. The relevant details have been described above and will not be repeated here.

[0218] Alternatively, the second elastic element 35 can be a spring or a torsion spring. If the second elastic element 35 is a torsion spring, it is rotatably connected to the second connecting shaft 34. The second inner rod 32a is provided with a fifth notch 325, and the surface of the second inner rod 32a used to enclose the fifth notch 325 is engaged with one end of the second elastic element 35. The second operating member 2 is provided with an eighth connecting hole 226, and the other end of the second elastic element 35 is inserted into the eighth connecting hole 226. If the second elastic element 35 is a spring (not shown in the figure), it can specifically be a compression spring or a tension spring.

[0219] Alternatively, please refer to Figure 14 As shown, in the second state, the connection position between the transmission section 31 and the first operating member 1 is the first position, and the rotational connection position between the drive section 32 and the second operating member 2 is the second position. A predetermined first connection line (e.g., ...) exists between the first position and the second position. Figure 14 As shown by the dotted line Δ, the extension direction of the first connecting line and the moving direction (direction X) of the first operating member 1 to the second operating member 2 have a set angle β, satisfying 0°≤β≤5°. Specifically, the angle β can be 0°, 1°, 2°, 3°, 4°, or 5°.

[0220] Please refer to Figure 14 As shown, the force exerted by the transmission section 31 on the first operating member 1 has a directional effect. Figure 14 The component force is set along the dotted line ε (parallel to direction X), which moves at least a portion of the structure of the first operating member 1 toward the second operating member 2 along direction X. This component force has a lever arm L (passing through the second position and perpendicular to the dotted line ε) between it and the second position. A set angle β (the angle β between the dotted line Δ and the dotted line ε) is formed between the first connecting line and this component force. When 0°≤β≤5°, the lever arm L is small, the torque formed by this component force at the second position is relatively small, and the structure of the second operating member 2 is less prone to deformation. Similarly, the torque formed by the force exerted by the drive segment 32 on the second operating member 2 at the first position is also relatively small, and the structure of the second operating member 2 is less prone to deformation. Therefore, the above configuration allows the surgical instrument 10 to complete medical procedures (e.g., circumcision in one procedure) with a high success rate, and also improves the surgical precision of the surgical instrument 10, thereby enhancing surgical safety.

[0221] Alternatively, please refer toFigure 3 As shown, the surgical instrument 10 includes at least two drive members 3. In the second state, the connection positions between each drive member 3 and the first operating member 1 are evenly distributed relative to the first operating member 1. Under this configuration, the force exerted by each drive member 3 on the first operating member 1 is evenly distributed, meaning the first operating member 1 is less prone to deformation, and each part of the first operating member 1 can reliably move according to the user-preset direction and distance. In the second state, the connection positions between each drive member 3 and the second operating member 2 are evenly distributed relative to the second operating member 2. Under this configuration, the force exerted by each drive member 3 on the second operating member 2 is evenly distributed, meaning the second operating member 2 is less prone to deformation, and each part of the second operating member 2 can reliably move according to the user-preset direction and distance. These configurations enable the surgical instrument 10 to complete medical procedures (e.g., circumcision in one procedure) with a high success rate, and also improve the surgical precision of the surgical instrument 10, thereby enhancing surgical safety.

[0222] Alternatively, please refer to Figure 3 As shown, since the driving component 3 includes a linkage structure, it can extend approximately in a direction parallel to the direction from the first operating component 1 to the second operating component 2 (along direction X). When the first operating component 1 and the second operating component 2 are fitted onto the organ 20 (e.g., the penis), the extension direction of the driving component 3 is approximately parallel to the extension direction of the organ 20 (e.g., the penis). When the user is lying down, the extension direction of the driving component 3 and the extension direction of the organ 20 (e.g., the penis) can both be set in an approximately horizontal direction (parallel to the top surface of the operating table). In this configuration, when the user's hand is operating the driving component 3, neither the driving component 3 nor the user's hand can obstruct the organ 20, allowing the user to perform medical procedures under direct vision, resulting in better medical outcomes. Furthermore, this configuration allows the user's hand to operate the driving component 3 in a more comfortable position, reducing the difficulty of operation.

[0223] Alternatively, please refer to Figure 3 As shown, in the second state, the first operating member 1 and the second operating member 2 are slidably connected. When at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 move toward each other, the slidable connection between the first operating member 1 and the second operating member 2 allows at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 to move in a directional manner (movement in a direction parallel to direction X), so that at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 reliably move in the direction preset by the user, thereby increasing the surgical precision of the surgical instrument 10 and improving the safety of the surgery.

[0224] Please refer to Figure 15 As shown, the first operating component 1 may be provided with a first sliding groove 1111. Please refer to...Figure 16 As shown, the second operating member 2 may include a slider 211. The slider 211 can slidably engage with the first sliding groove 1111, so that the first operating member 1 and the second operating member 2 are slidably connected. Optionally, the first operating member 1 may be provided with two first sliding grooves 1111 symmetrical with respect to the first operating member 1, and the second operating member 2 may include two sliders 211 symmetrical with respect to the second operating member 2. Optionally, in other embodiments (not shown in the figure), the first operating member 1 may be provided with multiple first sliding grooves 1111, and the second operating member 2 may include multiple sliders 211. Optionally, in other embodiments (not shown in the figure), the first operating member 1 may include sliders 211, and the second operating member 2 may be provided with first sliding grooves 1111. The following content mainly describes the first operating member 1 with two symmetrical first sliding grooves 1111 and the second operating member 2 with two symmetrical sliders 211 as examples.

[0225] Additionally, please refer to Figure 15 As shown, the first operating element 1 may be provided with a first sliding hole 1113. Please refer to... Figure 16 As shown, the second operating member 2 may include a first sliding rod 213. The first sliding rod 213 and the first sliding hole 1113 can be slidably engaged to allow the first operating member 1 and the second operating member 2 to be slidably connected. Optionally, the first operating member 1 may be provided with two first sliding holes 1113 symmetrical with respect to the first operating member 1, and the second operating member 2 may include two first sliding rods 213 symmetrical with respect to the second operating member 2. Optionally, in other embodiments (not shown in the figure), the first operating member 1 may be provided with multiple first sliding holes 1113, and the second operating member 2 may include multiple first sliding rods 213. Optionally, in other embodiments (not shown in the figure), the first operating member 1 may include a first sliding rod 213, and the second operating member 2 may be provided with a first sliding hole 1113. The following content mainly describes the first operating member 1 with two symmetrical first sliding holes 1113 and the second operating member 2 with two symmetrical first sliding rods 213 as examples.

[0226] Alternatively, please refer to Figure 15 and Figure 16 As shown, in the second state, either the first operating member 1 or the second operating member 2 includes a first latching part 1112, and the other includes a second latching part 212, and the first latching part 1112 and the second latching part 212 are latched together.

[0227] Please refer to Figure 13As shown, when the first operating member 1 and the second operating member 2 are slidably connected, and before at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 begin to move toward each other, the user can engage the first locking part 1112 with the second locking part 212 to fix the first operating member 1 and the second operating member 2 relatively, thereby reducing the likelihood of the first operating member 1 and the second operating member 2 separating before at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 move toward each other. This allows the user's hand to operate other parts within the surgical instrument 10, thus reducing the difficulty of operating the surgical instrument 10 and improving the user experience.

[0228] Please refer to Figure 14 As shown, when the user-operated drive 3 drives at least a portion of the structure of the first operating element 1 and at least a portion of the structure of the second operating element 2 to move towards each other, as... Figure 15 The first snap-fit ​​part 1112 shown can be connected to, as shown in the figure Figure 16 The second locking part 212 shown engages to fix the first operating member 1 and the second operating member 2 relative to each other, so that the surgical instrument 10 can reliably perform medical operations. For example, the temporary relative fixation of the first operating member 1 and the second operating member 2 can reliably cut the surface tissue 202 (e.g., foreskin), reducing the possibility of incomplete cutting of the surface tissue 202; the temporary relative fixation of the first operating member 1 and the second operating member 2 can also stably compress the cut site of the surface tissue 202, reducing bleeding; the temporary relative fixation of the first operating member 1 and the second operating member 2 can also limit the cut site of the surface tissue 202, reducing the possibility of infection due to contact with contaminants by random movement of the cut site of the surface tissue 202.

[0229] The first latching portion 1112 can be a protruding structure, and the second latching portion 212 can be a recessed structure; or, the first latching portion 1112 can be a recessed structure, and the second latching portion 212 can be a protruding structure; or, both the first latching portion 1112 and the second latching portion 212 can be hook structures.

[0230] In addition, the first locking part 1112 is disposed in the first operating member 1 to enclose the surface forming the first sliding groove 1111, and the second locking part 212 is disposed in the slider 211 of the second operating member 2. This arrangement has the advantage of high structural compactness, so that the first operating member 1 and the second operating member 2 are smaller in size, the area of ​​the organ 20 obscured by the first operating member 1 and the second operating member 2 is smaller, and the user can observe the state of the organ 20 through a wider field of view.

[0231] Alternatively, please refer to Figures 13-14As shown, the first operating component 1 includes a pusher 11, a staple cartridge 12, and a cutting blade 13. The pusher 11 is detachably connected to the driving component 3. The staple cartridge 12 is sleeved on and slidably connected to the outer wall of the pusher 11. The pusher 11 is used to push the cutting blade 13 and the staples 4 placed in the staple cartridge 12 (e.g., ...). Figure 17 (As shown).

[0232] In the first state, the user first places the first operating element 1 on the organ 20 (penis), and then the user everts the surface tissue 202 (foreskin) of the organ 20 so that the surface tissue 202 (foreskin) covers the sidewall of the first operating element 1. After this, the user places the second operating element 2 on the exposed part (e.g., the glans) of the main body 201. In the second state, the user operates the driving element 3 to drive the pushing element 11 to move in the X direction toward the second operating element 2. The pushing element 11 can push the cutting blade 13 toward the second operating element 2 so that the cutting blade 13 cuts the surface tissue 202. The pushing element 11 can also push the anastomosis staples 4 pre-placed in the staple cartridge 12 so that the anastomosis staples 4 pierce the surface tissue 202 and deform to compress the two sides of the surface tissue 202. That is, the anastomosis staples 4 can bandage the cut site of the surface tissue 202 to reduce the amount of bleeding at the cut site of the surface tissue 202.

[0233] Since the staple cartridge 12 is slidably connected to the pusher 11, as the pusher 11 moves in the direction X toward the second operating member 2, the staple cartridge 12 abuts against the side of the surface tissue 202 away from the second operating member 2. The staple cartridge 12 is limited by the surface tissue 202 and the second operating member 2. As the pusher 11 slides toward the second operating member 2 relative to the staple cartridge 12, the pusher 11 pushes out the cutting blade 13 and the anastomotic staple 4, which were not originally protruding relative to the staple cartridge 12.

[0234] Alternatively, please refer to Figure 18 As shown, the cutting blade 13 includes a connected annular blade 131 and an extension 132. One end of the annular blade 131, facing away from the annular blade 131, abuts against the staple cartridge 12. The extension 132 is connected to the outer wall of the pusher 11. In this configuration, the staple cartridge 12 is confined by the cutting blade 13, reducing the likelihood of the staple cartridge 12 disengaging from the pusher 11 in the X direction.

[0235] Among them, the ring cutter 131 has at least two extensions 132 connected to the side opposite to the cutting edge 1311.

[0236] Alternatively, please refer to Figure 18As shown, the outer wall of the pusher 11 includes a first protrusion 1122, and the extension 132 is provided with a second hollow groove 1321. The first protrusion 1122 passes through the second hollow groove 1321, so that the pusher 11 and the cutting blade 13 are detachably connected. With this configuration, the user can replace the cutting blade 13 with different sizes and structural types without replacing the entire surgical instrument 10 to meet different surgical needs. The user can also replace the cutting blade 13 with different sharpness without replacing the entire surgical instrument 10, thus extending the service life of the surgical instrument 10. Secondly, during the movement of the pusher 11 towards the second operating member 2, when the cutting blade 13 abuts against the surface tissue 202, since the first protrusion 1122 can still slide relative to the second hollow groove 1321, the cutting blade 13 slides a set distance relative to the pusher 11 in the opposite direction to direction X. This prevents the cutting blade 13 from immediately cutting the surface tissue 202, while the pusher 11 can reliably push the anastomosis staple 4 to first bandage the area of ​​the surface tissue 202 to be cut. After the cutting blade 13 slides relative to the pusher 11 to the set position in the opposite direction to direction X, the pusher 11 can reliably push the cutting blade 13 to cut the surface tissue 202. Under this configuration, since the surgical instrument 10 first bandages the area of ​​the surface tissue 202 to be cut with the anastomosis staple 4 before cutting the surface tissue 202, the surface tissue 202 is pre-stopped from bleeding. When cutting the surface tissue 202, the amount of bleeding is less, which facilitates postoperative cleaning and reduces the possibility of infection in the patient.

[0237] In other embodiments (not shown in the figures), the outer wall of the pusher 11 may be provided with a second hollowed-out groove 1321, and the extension 132 may include a first protrusion 1122, which passes through the second hollowed-out groove 1321. The following content mainly describes the pusher 11 with the outer wall including the first protrusion 1122 and the extension 132 being provided with the second hollowed-out groove 1321 as an example.

[0238] Alternatively, please refer to Figure 14 As shown, since the annular blade 131 surrounds the outer wall of the staple cartridge 12 at one end facing the second operating member 2, the annular blade 131 is exposed relative to the staple cartridge 12, so that the user can accurately determine the relative distance between the annular blade 131 and the preset cutting position of the surface tissue 202 when turning the surface tissue 202 outward, thereby facilitating the user to accurately cut the surface tissue 202.

[0239] Optionally, the pusher 11 includes a first connecting portion 111 (such as...). Figures 18-19 (as shown), second connecting part 112 (as shown) Figures 18-19 (as shown) and the third connecting part 113 (as shown) Figure 20(As shown). The first connecting part 111 and the second connecting part 112 are integrally formed and connected, and the third connecting part 113 is detachably connected to the second connecting part 112. The first connecting part 111 is provided with the first sliding groove 1111, the first snap-fit ​​part 1112 and the first sliding hole 1113 described above. The second connecting part 112 has a generally annular structure. The outer wall of the second connecting part 112 includes the first protrusion 1122 described above. The second connecting part 112 is also provided with a first through hole 1125 for the organ 20 to pass through. A third recess 1116 is provided on the side of the first connecting part 111 that is away from the second operating member 2. When the third connecting part 113 is not installed, the third recess 1116 communicates with the first through hole 1125. The third recess 1116 is used to accommodate at least a portion of the structure of the third connecting portion 113. A fourth connecting hole 1119 is provided on the surface of the first connecting portion 111 that encloses the third recess 1116. The third connecting portion 113 is provided with a fifth connecting hole 1134. A connector (not shown in the figure, such as a screw or pin) can pass through the fourth connecting hole 1119 and the fifth connecting hole 1134 to allow the first connecting portion 111 and the third connecting portion 113 to be detachably connected. The third connecting portion 113 is annular and is provided with a second through hole 1132, which can communicate with the first through hole 1125. The second through hole 1132 is also used for the organ 20 to pass through. The end face of the third connecting portion 113 that abuts against the first connecting portion 111 is provided with a fourth recess 1133. The first connecting portion 111 includes a second protrusion 1117 located within the third recess 1116. The second protrusion 1117 and the fourth recess 1133 are mutually restrictive and engaged, so that the first connecting portion 111 and the third connecting portion 113 are connected in a restricted manner, thereby limiting the rotation of the third connecting portion 113 around the axis of the first through hole 1125. The end face of the third connecting portion 113 opposite to the first connecting portion 111 is provided with two symmetrically arranged first recesses 1131, so that the third connecting portion 113 can be detachably connected to the transmission section 31 of the driving member 3. The materials of the first connecting portion 111 and the second connecting portion 112 can be carbon fiber or plastic, etc., to reduce the weight of the first operating member 1, reduce the burden on the user's hands, and improve the user experience. The material of the third connecting part 113 can be metal. The third connecting part 113 has high rigidity. The force applied by the third connecting part 113 driven by the driving member 3 to the first connecting part 111 is relatively uniform. The overall structure of the first operating member 1 is not easily deformed.

[0240] Alternatively, please refer to Figure 18As shown, the outer wall of the second connecting portion 112 includes a first sliding portion 1121, and the inner wall of the staple cartridge 12 is provided with a third sliding groove 1212. The first sliding portion 1121 and the third sliding groove 1212 are slidably engaged to allow the second connecting portion 112 and the staple cartridge 12 to be slidably connected. The outer wall of the second connecting portion 112 is provided with a second sliding groove 1124, and the inner wall of the staple cartridge 12 includes a second sliding portion 1211. The second sliding portion 1211 and the second sliding groove 1124 are slidably engaged to allow the second connecting portion 112 and the staple cartridge 12 to be slidably connected. The second protrusion 1117 protrudes relative to the first sliding portion 1121. The first sliding portion 1121 includes a first step 1121a and a second step 1121b. The first step 1121a is used to limit the sliding stroke of the pusher 11 relative to the staple cartridge 12 by engaging with the end of the staple storage portion 122 that is away from the second operating member 2. The second step 1121b is used to limit the sliding stroke of the pusher 11 relative to the staple cartridge 12 by engaging with the end of the extension portion 132 that is away from the annular blade 131, so that the cutting blade 13 is reliably pushed by the pusher 11. The second connecting portion 112 also includes a plurality of pushers 1123 arranged circumferentially around the axis of the first through hole 1125, each pusher 1123 being used to push the corresponding staple 4.

[0241] Alternatively, please refer to Figure 18 As shown, the staple cartridge 12 includes a fourth connecting portion 121 and a staple storage portion 122 connected together. The fourth connecting portion 121 is annular and has a third through hole 1218. The staple storage portion 122 is annular and has a fourth through hole 1223. The third through hole 1218 and the fourth through hole 1223 are connected. The diameter of the third through hole 1218 is smaller than the diameter of the fourth through hole 1223. Both the third through hole 1218 and the fourth through hole 1223 are used for insertion by the organ 20. The fourth connecting portion 121 includes the second sliding portion 1211 and the third sliding groove 1212 described above. The fourth connecting portion 121 also includes a third step 1213, which is limited and abutted by the end of the annular blade 131 that is away from the blade edge 1311. The third step 1213 is provided with a connecting port 1214, which communicates with the third slide groove 1212. The connecting port 1214 is penetrated by the extension 132 of the cutting blade 13, so that the extension 132 extends into the third slide groove 1212 and connects with the pusher 11. The staple storage section 122 is provided with a receiving cavity 1222 penetrating through the staple storage section 122. The receiving cavity 1222 is used to receive the anastomosis staples 4. The pusher 1123 can move into the receiving cavity 1222, so that the anastomosis staples 4 are pushed out of the staple storage section 122 and pierce the surface tissue 202. Specifically, the staple storage section 122 is provided with a plurality of receiving cavities 1222 arranged in a circumferential array around the axis of the fourth through hole 1223 to receive a plurality of anastomosis staples 4. Please refer to Figure 21As shown, the staple storage section 122 has a set total wall thickness width W1, satisfying 1.5mm ≤ W1 ≤ 2.5mm. Specifically, the total wall thickness width W1 can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, or 2.5mm. The smaller wall thickness width W1 of the staple storage section 122 facilitates the outward turning and fixing of more parts of the surface tissue 202 to the outer wall of the staple cartridge 12, thereby reducing the possibility of inaccurate cutting positions due to the free movement of more parts of the surface tissue 202. The nail storage section 122 has a set single-sided wall thickness width W2, which satisfies 0.4mm≤W2≤0.6mm. Specifically, the single-sided wall thickness width W2 can be 0.41mm, 0.42mm, 0.43mm, 0.44mm, 0.45mm, 0.46mm, 0.47mm, 0.48mm, 0.49mm, 0.5mm, 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, or 0.6mm. In this setting, the unilateral wall thickness W2 is smaller. First, it facilitates the eversion of the surface tissue 202. Second, since the unilateral wall thickness W2 corresponds to the cutting position of the surface tissue 202, the smaller unilateral wall thickness W2 makes it easier for doctors to accurately determine the cutting position of the surface tissue 202. In addition, the smaller unilateral wall thickness W2 results in a smaller gap between the blade 1311 and the anastomosis staple 4 placed in the receiving cavity 1222. This makes the position of the anastomosis staple 4 bandaging the surface tissue 202 closer to the position where the surface tissue 202 is cut by the blade 1311, which can reduce the amount of bleeding at the cut site of the surface tissue 202. Moreover, the anastomosis staple 4 can play a positioning role for the part of the surface tissue 202 near the cutting position, thereby reducing the possibility that the part of the surface tissue 202 near the cutting position will be stretched or compressed significantly due to the cutting force, thus reducing the degree of damage to the part of the surface tissue 202 near the cutting position.

[0242] Alternatively, please refer to Figure 18 As shown, the nail storage section 122 has an end portion 1221 that can face the second operating member 2. Please refer to... Figure 22As shown, the surgical instrument 10 may also include an annular insert 16. The annular insert 16 can be penetrated by the organ 20 and is positioned at the end 1221 to cover the opening of the receiving cavity 1222. When the anastomosis staple 4 is pushed out of the receiving cavity 1222, the staple 4 first pierces the annular insert 16 and then the surface tissue 202. Because the annular insert 16 reduces the compressive pressure of the staple 4, it reduces the likelihood of the staple 4 completely penetrating the surface tissue 202, resulting in an excessively large wound area on the surface tissue 202. Alternatively, it reduces the likelihood of part of the staple 4 becoming embedded inside the surface tissue 202, making it difficult to separate the staple 4 from the surface tissue 202 during subsequent removal. Please refer to [reference needed]. Figure 22 As shown, the annular auxiliary piece 16 is provided with multiple circumferential array first notches 161, so that the annular auxiliary piece 16 is divided into multiple sub-auxiliary pieces 163 by the first notches 161. The connection between each two adjacent sub-auxiliary pieces 163 is a weak connection or a flexible connection. Each sub-auxiliary piece 163 corresponds to an individual anastomosis staple 4, so that when each sub-auxiliary piece 163 is subjected to the force of the corresponding anastomosis staple 4, the influence on the other sub-auxiliary piece 163 is minimized, that is, the possibility of positional displacement of each sub-auxiliary piece 163 is reduced, thereby improving the accuracy of the fit between each sub-auxiliary piece 163 and the corresponding anastomosis staple 4. Secondly, since the local tissue of the postoperative organ 20 will experience edema, each sub-auxiliary piece 163 can be radially offset relative to other sub-auxiliary pieces 163 along the annular auxiliary piece 16, so as to reduce the pressure of the annular auxiliary piece 16 on the edematous part of the postoperative organ 20, improve comfort, and reduce the possibility of necrosis of the local tissue of the organ 20. Furthermore, the connection structure between any two adjacent sub-adhesive pieces 163 is relatively weak, making it easy to disconnect the annular adhesive piece 16 postoperatively, thus facilitating the user's removal of the annular adhesive piece 16 from the organ 20. Even with the first notch 161, the annular adhesive piece 16 still maintains an annular structure, making it easy for the user to place the annular adhesive piece 16 onto the organ 20 before surgery.

[0243] The end 1221 is provided with a plurality of mounting holes 1224. The annular auxiliary piece 16 includes a plurality of connecting posts 162, which are installed in the mounting holes 1224. This arrangement can restrict the movement of the annular auxiliary piece 16 relative to the end 1221, reduce the possibility of the annular auxiliary piece 16 detaching from the end 1221, and enable each sub-auxiliary piece 163 to accurately cover the opening of the corresponding receiving cavity 1222.

[0244] Alternatively, please refer to Figures 12-14 As shown, the first operating member 1 also includes a limiting member 14, which is movably connected to the outer wall of the staple cartridge 12. The limiting member 14 can move relative to the staple cartridge 12 to a position where it is limited to or separated from the pusher 11.

[0245] The limiting member 14 is movably connected to the outer wall of the staple cartridge 12, so that the limiting member 14 is in at least two positions relative to the staple cartridge 12. Please refer to... Figure 13 As shown, under non-use conditions, the limiting member 14 is positioned in a limiting connection with the pusher 11, and the limiting member 14 can restrict the pusher 11 from sliding relative to the staple cartridge 12 in the X direction. Please refer to... Figure 14 As shown, during the operation, the user can operate the limiting member 14 to separate from the pushing member 11. The pushing member 11 is not limited by the limiting member 14 and can slide relative to the staple cartridge 12 in the X direction. Therefore, the setting of the limiting member 14 can reduce the possibility of the surgical instrument 10 being accidentally triggered under non-use conditions.

[0246] Specifically, the movable connection between the limiting member 14 and the outer wall of the staple cartridge 12 can be a sliding connection or a rotating connection, which can change the position of the limiting member 14 relative to the staple cartridge 12.

[0247] Alternatively, please refer to Figure 23 As shown, the limiting member 14 is annular and can be fitted onto the staple cartridge 12. The limiting member 14 includes a third sliding portion 141. Please refer to... Figure 18 As shown, the staple cartridge 12 is provided with a spiral-shaped fourth groove 1217. The third sliding part 141 slides in conjunction with the fourth groove 1217 to allow the limiting member 14 and the staple cartridge 12 to be spirally connected. The user can operate the limiting member 14 to rotate spirally relative to the staple cartridge 12 to change the position of the limiting member 14 relative to the staple cartridge 12, thereby placing the limiting member 14 in a position limitedly connected to the pusher 11 or in a position separated from the pusher 11. The above arrangement allows the user's hand to grasp the first operating member 1 while simultaneously using the fingers of the hand grasping the first operating member 1 to move the limiting member 14, reducing the difficulty of operation for the user's hands.

[0248] The third sliding part 141 can also be spiral-shaped, and the surface of the fourth sliding groove 1217 in the pin magazine 12 that forms the groove is in surface contact with the third sliding part 141. Please refer to... Figure 24 As shown, the helical third sliding part 141 and the fourth sliding groove 1217 have a helix angle λ, satisfying 15°≤λ≤20°. The helix angle λ can specifically be 15°, 16°, 17°, 18°, 19°, or 20°. Under this configuration, the surface of the fourth sliding groove 1217 in the staple cartridge 12 that forms the fourth sliding groove and the surface of the third sliding part 141 can achieve self-locking (due to the large static friction, they do not move). If a force is applied to the limiting member 14 in the direction X, the limiting member 14 is difficult to rotate helically relative to the staple cartridge 12. When the limiting member 14 abuts against the pushing member 11, the limiting member 14 can reliably limit the pushing member 11.

[0249] In addition, the fourth groove 1217 is located on the outer side wall of the fourth connecting part 121 of the staple cartridge 12.

[0250] Furthermore, the limiting member 14 is provided with a fifth through hole 142, through which the pushing member 11 passes, and the third sliding part 141 is provided in the limiting member 14 to enclose the curved sidewall that forms the fifth through hole 42.

[0251] In other embodiments (not shown in the figures), the limiting member 14 may be provided with a spiral-shaped fourth slide groove 1217, and the staple cartridge 12 may include a third sliding part 141, which slides in cooperation with the fourth slide groove 1217 so that the limiting member 14 and the staple cartridge 12 are spirally slidably connected.

[0252] The following content mainly describes the limiting member 14, including the third sliding part 141 and the staple cartridge 12, which is provided with a spiral-shaped fourth sliding groove 1217.

[0253] Alternatively, please refer to Figure 23 As shown, the limiting member 14 is provided with a second annular groove 143. Please refer to... Figure 18 As shown, the outer wall of the staple cartridge 12 includes a fourth protrusion 1216. The fourth protrusion 1216 can engage with the surface of the limiting member 14 used to enclose and form the second annular groove 143, thereby limiting the limiting member 14 to a position separated from the pusher 11 and reducing the possibility of the limiting member 14 interfering with the sliding of the pusher 11 relative to the staple cartridge 12. Furthermore, the structure of the second annular groove 143 allows the fourth protrusion 1216 to engage with any part of the surface of the limiting member 14 used to enclose and form the second annular groove 143, resulting in lower operational difficulty and a better user experience.

[0254] The fourth protrusion 1216 is located on the outer side wall of the fourth connecting part 121 of the staple cartridge 12.

[0255] Alternatively, please refer to Figures 13-14 As shown, the first operating member 1 also includes a reset member 15 and a third elastic member (not shown in the figure). The reset member 15 is connected to the pusher 11 through the third elastic member. The side of the reset member 15 that is away from the third elastic member is connected to the end of the staple cartridge 12 that is away from the second operating member 2. The third elastic member is in a compressed state.

[0256] Please refer to Figure 13 As shown, when the third elastic element (not shown) is in a compressed state, the third elastic element has a spring force along the X direction on the reset element 15, so that the reset element 15 limits the staple cartridge 12 to prevent the cutting blade 13 and the staple 4 from protruding relative to the staple cartridge 12. Please refer to... Figure 14As shown, when the pusher 11 moves relative to the staple cartridge 12 toward the second operating member 2, the staple cartridge 12, which is limited by the second operating member 2, slides relative to the pusher 11 in the opposite direction of the X direction, so that the cutting blade 13 and the staple 4 protrude relative to the staple cartridge 12. Simultaneously, the staple cartridge 12 applies a force to the third elastic member through the reset member 15, further compressing the third elastic member and accumulating elastic potential energy. When the staple cartridge 12 is not limited by the second operating member 2, the elastic force of the third elastic member can push the reset member 15, causing the reset member 15 to push the staple cartridge 12 to slide relative to the pusher 11 in the X direction, thereby automatically resetting the staple cartridge 12 relative to the pusher 11. Figure 13 The location shown.

[0257] Alternatively, please refer to Figure 25 As shown, the reset component 15 includes a second slide bar 151. Please refer to... Figure 18 As shown, the first connecting portion 111 of the pusher 11 is provided with a second sliding hole 1114, and the second sliding rod 151 is slidably engaged with the second sliding hole 1114, so that the reset member 15 is slidably connected with the first connecting portion 111. The reset member 15 can slide with the first connecting portion 111 in a direction parallel to the X direction. The reset member 15 is provided with a sixth through hole 152, which is used for the second connecting portion 112 to pass through. The first connecting portion 111 is provided with an inwardly recessed second recessed portion 1115, and at least a portion of the reset member 15 is located in the second recessed portion 1115. With this configuration, the structure of the first operating member 1 is highly compact, so that the size of the first operating member 1 is small, making it easy for the user to operate and providing a better user experience. The reset member 15 also includes a second stop portion 153, and the first connecting portion 111 also includes a first stop portion 1118. The second stop portion 153 is limitedly connected to the first stop portion 1118, restricting the reset member 15 from being pushed out of the second recess 1115 by the third elastic member.

[0258] Alternatively, please refer to Figure 26 As shown, the surgical instrument 10 also includes a retaining ring 5, which is used to fix the everted portion of the surface tissue 202 to the outer wall of the first operating member 1. The outer wall of the fourth connecting portion 121 of the staple cartridge 12 of the first operating member 1 is provided with a first annular groove 1215, which is used to accommodate at least a portion of the retaining ring 5. The everted portion of the surface tissue 202 is fixed and clamped by the surface of the fourth connecting portion 121 that surrounds the first annular groove 1215 and the retaining ring 5. The retaining ring 5 is deformable so that the user can adjust the tightening force of the retaining ring 5.

[0259] Alternatively, please refer to Figure 16 As shown, the second operating member 2 includes a fifth connecting part 21 and a sixth connecting part 22 connected together. Please refer to... Figure 27As shown, the fifth connecting part 21 includes the slider 211, the second locking part 212, and the first sliding rod 213 described above. The fifth connecting part 21 also has a seventh through hole 214 for the organ 20 to pass through. Please refer to... Figure 28As shown, the sixth connecting portion 22 is provided with an eighth through hole 224 for the organ 20 to pass through. The sixth connecting portion 22 includes a third protrusion 221, which is provided with the second connecting hole 2211 described above. The third protrusion 221 is provided with a second space 2212, which is used to accommodate part of the structure of the driving section 32. The third protrusion 221 can restrict the movement of the driving section 32 along the axis of the second connecting hole 2211. The sixth connecting portion 22 is provided with an annular sixth recess 222. The surgical instrument 10 includes an annular anvil 23, which is installed in the sixth recess 222. The blade 1311 can move into the sixth recess 222 and abut against the anvil 23, thereby reliably cutting the surface tissue 202 by the blade 1311. The anvil 23 can be press-fitted with the sixth recess 222, or the anvil 23 can be bonded to the sixth connecting portion 22. The sixth connecting portion 22 is also provided with a seventh recess 223. After the sharp part of the anastomotic staple 4 pierces the surface tissue 202, it abuts against the surface of the sixth connecting portion 22 used to form the seventh recess 223. Since the surface of the sixth connecting portion 22 used to form the seventh recess 223 is an arc surface, the surface of the sixth connecting portion 22 used to form the seventh recess 223 can guide the sharp part of the anastomotic staple 4 to bend and deform until the sharp part of the anastomotic staple 4 is pressed against the side of the surface tissue 202 that can face the second operating member 2. The sixth connecting portion 22 is provided with a plurality of seventh recesses 223 arranged in a circumferential array around the axis of the eighth through hole 224, and each seventh recess 223 corresponds to a separate sharp part of the anastomotic staple 4. The fifth connecting part 21 is provided with a sixth connecting hole 218, and the sixth connecting part 22 is provided with a seventh connecting hole 225. A connector (not shown in the figure, a screw or pin) passes through the sixth connecting hole 218 and the seventh connecting hole 225, allowing the fifth connecting part 21 and the sixth connecting part 22 to be detachably connected. The fifth connecting part 21 is provided with a fifth recess 215, which accommodates at least a portion of the structure of the sixth connecting part 22. The fifth connecting part 21 is provided with a first clearance space 216, which accommodates at least a portion of the structure of the third protrusion 221. With this configuration, the second operating member 2 has a high degree of structural compactness and a small volume, making it easy for the user to operate and providing a better user experience. The fifth connecting part 21 is also provided with a second notch 217 for accommodating the drive section 32. With this configuration, the structure between the second operating member 2 and the drive member 3 is highly compact, the surgical instrument 10 is small, making it easy for the user to operate and providing a better user experience. The sixth connecting part 22 is provided with an eighth connecting hole 226, and one end of the second elastic member 35 (e.g., a torsion spring) that is away from the second inner rod 32a is inserted into the eighth connecting hole 226.

[0260] The working process of the surgical instrument 10 in this embodiment is as follows:

[0261] Please refer toFigure 1 As shown, the user can position the surgical instrument 10 in the first state. Please refer to... Figure 2 As shown, the user can place the first operating element 1 onto the organ 20 (penis) and evert the surface tissue 202 (foreskin). During this process, the user can adjust the relative position between the first operating element 1 and the organ 20, as well as the degree of eversion of the surface tissue 202 (foreskin). Optionally, the user can use the fixing ring 5 to fix the everted portion of the surface tissue 202 to the outer wall of the first operating element 1. Then, the user can place the second operating element 2 onto the organ 20. During this process, the user can independently adjust the relative position between the main body 201 of the organ 20 and the second operating element 2, and adjust the exposed portion of the main body 201 (e.g., the glans and the frenulum of the glans). Next, please refer to... Figure 3 As shown, the user engages the first operating element 1 and the second operating element 2, and connects the driving element 3 to the first operating element 1. The user then operates the limiting element 14 of the first operating element 1 to a position limited by its connection with the pushing element 11 (e.g., Figure 13 (As shown) Move to a position where it is not connected to the limit of the pusher 11 (e.g.) Figure 14 (As shown). Under this setting, please refer to... Figure 4 As shown, the user can operate the drive unit 3 to drive at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 to move towards each other, thereby causing the staple 4 placed on the first operating member 1 to wrap the surface tissue 202, and causing the cutting blade 13 to cut the surface tissue 202. Upon completion of the cutting, the first operating member 1 and the second operating member 2 re-engage. After cutting, please refer to... Figure 5 As shown, the user can release or reset the drive member 3. During this process, the first elastic element 33 inside the drive member 3 releases its elastic potential energy. The elastic force of the first elastic element 33 causes the transmission section 31 inside the drive member 3 to separate from the first operating member 1, so that the user cannot drive at least a portion of the structure of the first operating member 1 and at least a portion of the structure of the second operating member 2 to move towards each other again through the drive member 3. Finally, the user can disassemble the first operating member 1 and the second operating member 2 to detach the first operating member 1 and the second operating member 2 from the organ 20.
