[0049] In order to make the technical solutions and beneficial effects of the present invention more clearly understandable, the following is a detailed description by listing specific embodiments. The drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

[0050] In the description of the present invention, terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "height", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of simplified description of the present invention, and do not indicate that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and should not be understood as a limitation to the present invention.

[0051] In the present invention, the terms "first" and "second" are only used for the purpose of clear description and cannot be understood as the relative importance of the indicated features or the number of the indicated technical features. Therefore, the features defined as "first" and "second" can explicitly include at least one of the features. In the description of the present invention, "multiple" means at least two, such as two, three, etc.; "several" means at least one, such as one, two, three, etc., unless otherwise clearly and specifically defined.

[0052] In the present invention, unless otherwise clearly defined, the terms "install", "connect", "connect", "fix", "set", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] In the present invention, unless otherwise clearly defined, a first feature being “on”, “above”, “above”, “below”, “below”, “below” or “below” a second feature may mean that the first feature is in direct contact with the second feature, or the first feature and the second feature are in indirect contact with each other through an intermediate medium. Moreover, a first feature being “on”, “above” or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than the horizontal height of the second feature. A first feature being “below”, “below” or “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than the horizontal height of the second feature.

[0054] like Figures 1 to 3 As shown, the foreskin stapler 100 (hereinafter referred to as "stapler") includes a housing 10, anastomosis assembly 30, firing assembly 50 and anvil 20. The anvil 20 includes a receiving groove 210 for receiving the glans penis. During the operation, the glans penis is placed in the receiving groove 210, and the foreskin a to be cut is stretched proximally to cover the receiving groove 210 and fixed, so that the firing assembly 50 is used to fire the anastomosis assembly 30 and the anvil 20 for anastomosis and cutting.

[0055] The kiss cutting assembly 30 includes a staple cartridge assembly 310, a staple pusher assembly 320 and a cutting knife 330. The cutting knife 330 is an annular structure. The staple cartridge assembly 310 includes an annular staple cartridge 311 and a staple cartridge sleeve 312. The staple cartridge 311 contains suture staples, and the staple cartridge 311 is installed on the staple cartridge sleeve 312. The staple pusher assembly 320 includes a staple pusher block 321 and a staple pusher body 322. A plurality of staple pusher blocks 321 are circumferentially distributed around the axis of the annular cutting knife 330. The staple pusher block 321 is used to push out the suture staples in the staple cartridge 311 and act on the foreskin. The cutting knife 330 is connected to the staple pusher body 322. The staple pusher body 322 moves under the firing action of the firing assembly 50 and drives the staple pusher block 321 and the cutting knife 330 to move, so that both the suture staples and the cutting knife 330 act on the foreskin.

[0056] The anastomosis assembly 30 also includes a gasket ring 340, which is embedded in a first annular groove 211 formed by the outward turn of the end of the accommodating groove 210 of the stapler 20. The material of the gasket ring 340 is generally plastic or rubber. When the cutting knife 330 acts on the gasket ring 340 after completing the cutting, the gasket ring 340 can absorb the large impact force generated by the cutting knife 330 during cutting, thereby ensuring the cutting effect of the stapler.

[0057] The firing assembly 50 includes a firing handle 510 and a firing push block 520. The firing handle 510 is movably mounted on the outside of the shell 10. Under the firing action of the firing handle 510, the firing push block 520 moves along the axial direction of the shell 10 and pushes the nail push assembly 320 to move, so as to suture and cut the foreskin covering the accommodating groove 210.

[0058] The stapler also includes an adjusting member 60, which is connected to the proximal end of the shell 10. An internal thread is provided inside the adjusting member 60, and an external thread matching the internal thread is provided at the end of the nail support 20 near the adjusting member 60. The adjusting member 60 is rotated to adjust the position of the nail support 20 relative to the shell 10, and then the distance between the nail support 20 and the nail magazine 311 and the cutting knife 330 is adjusted, so that the distance between the nail support 20 and the nail magazine 311 reaches a distance that can safely close the nail height, thereby ensuring the forming effect of the staples.

[0059] According to the related technology, after the cutting knife 330 completes the cutting of the foreskin and acts on the knife pad 340, there is no obvious operation prompt during the entire operation process. For less experienced doctors, it is impossible to confirm whether the cutting is completed, which may affect the cutting efficiency and cutting effect.

[0060] Based on this, the stapler provided in the embodiment of the present application has a sound piece 40 installed between the gasket ring 340 and the first annular groove 211. When the cutting knife 330 performs the cutting action, the cutting knife 330 first cuts the foreskin, and then hits the surface of the sound piece 40 after cutting the gasket ring 340, making an impact sound, so as to auditorily prompt the doctor that the cutting knife 330 has completed cutting the foreskin.

[0061] Specifically, Figure 1 , Figure 4a and Figure 4b As shown, the stapler further includes a sounding member 40, which is located between the washer ring 340 and the bottom of the first annular groove 211, and a first space 4a is provided between the sounding member 40 and the bottom of the first annular groove 211. The sounding member 40 and the washer ring 340 are separately provided. When the firing assembly 50 is fired, the firing push block 520 pushes the cutting knife 330 to the distal direction, i.e., Figure 4a Move in the direction of arrow s1 shown in the figure, the cutting knife 330 first cuts the foreskin and then cuts the gasket ring 340. After completing the cutting of the gasket ring 340, the cutting knife 330 hits the surface of the sound piece 40, making a knocking sound to prompt the doctor that the foreskin cutting action is completed at this time.

[0062] Figure 4a and Figure 4b Schematic diagram showing the state of the cutting knife 330, the knife washer 340 and the sounding member 40 before the firing push block 520 is fired. Figure 4b FIG. 1 shows a schematic diagram of a state in which a portion of the foreskin a to be cut is covered on the surface of the anvil 20 and is located between the washer ring 340 and the cutting knife 330 in the axial direction of the housing 10. The axial direction of the housing 10 is Figure 4a The direction of arrow s1 is shown in FIG.

[0063] In this embodiment, the sound piece 40 and the first annular groove 211 form a drum-like structure. When the cutting knife 330 hits the surface of the sound piece 40, it is similar to hitting the surface of the drum structure. The surface of the sound piece 40 vibrates under the impact of the cutting knife 330, thereby making a sound.

[0064] Generally, the material of the cutting blade 330 is a metal with high hardness and strength. When the metal cutting blade 330 hits the surface of the metal sounding piece 40, a clear and bright sound can be emitted, which is convenient for the doctor to recognize the sound. As an example, the cutting blade 330 is made of stainless steel, and the sounding piece 40 is also made of stainless steel. Of course, the cutting blade 330 and the sounding piece 40 can also be made of other metal materials.

[0065] In an optional embodiment, the sound piece 40 is a thin-sheet structure. When the cutting knife 330 hits the sound piece 40 made of a metal thin-sheet structure, the thin-sheet sound piece 40 is similar to a drum skin of a drum structure, which can generate a large amplitude and cause the air in the first space 4a to vibrate, thereby making the sound generated after the cutting knife 330 hits the sound piece 40 more obvious.

[0066] In an optional embodiment, the washer ring 340 and the sounding member 40 are annular structures. The washer ring 340 and the sounding member 40 of the annular structure can completely match the first annular groove 211, and can maximize the role of the washer ring 340 and the sounding member 40. Of course, the washer ring 340 and the sounding member 40 can also be other structures, such as: semicircular structure, which is not limited in the embodiment of the present application.

[0067] In an alternative embodiment, if Figure 4b , Figure 5a and Figure 5b As shown, the washer ring 340 is provided with a second annular groove 341 , and the opening of the second annular groove 341 faces the bottom of the first annular groove 211 .

[0068] Furthermore, a second space is defined between the bottom of the second annular groove 341 and the sounding member 40 .

[0069] It can be understood that when the cutting knife 330 performs the cutting action, after the cutting knife 330 cuts off the gasket ring 340, due to the second space between the bottom of the second ring groove 341 and the sound piece 40, the cutting knife 330 accelerates due to the lack of resistance, and the doctor can feel an obvious sense of drop, thereby being able to tactilely remind the doctor that the foreskin cutting is completed.

[0070] With the above stapler, when the cutting knife 330 performs the cutting action, a sense of drop can be felt by the sense of touch after the cutting knife 330 completes the cutting of the gasket ring 340, and a sound of impact can be felt by the sense of hearing when the cutting knife 330 hits the surface of the sound piece 40. The stapler reminds the doctor that the foreskin has been cut by both the sense of touch and the sense of hearing, and the prompting effect is obvious, which greatly improves the cutting efficiency of the foreskin and can also improve the cutting effect.

[0071] In an alternative embodiment, if Figure 5a , Figure 5b and 6a As shown, the washer ring 340 is provided with a plurality of sound amplification holes 342 , and the plurality of sound amplification holes 342 are located on the groove wall of the second annular groove 341 .

[0072] Figure 6a FIG. 4 shows a schematic diagram of the three-dimensional structure of the washer ring 340 and the sounding member 40. Figure 6aAs shown, the inner and outer rings of the knife washer 340 are both provided with a sound expansion hole 342, which is used to diffuse the impact sound generated when the cutting knife 330 hits the surface of the sound piece 40, so as to improve the diffusion effect of the impact sound, thereby improving the prompt effect to the doctor.

[0073] Preferably, the plurality of sound expansion holes 342 are evenly distributed along the circumference of the washer ring 340 to improve the diffusion uniformity of the impact sound.

[0074] The number of the sound expansion holes 342 can be set according to the size of the sound expansion holes 342. In addition, the shape of the sound expansion holes 342 can be circular, square, elliptical, triangular, irregular, etc. The embodiment of the present application does not make specific limitations, and the impact sound can clearly alert the doctor.

[0075] Figure 4b The sound member 40 shown in FIG. 4 is a planar structure. Figure 4c The sound member 40 shown in FIG. 4 is a hollow structure.

[0076] Specifically, Figure 4c , Figure 6b , Figure 7a and Figure 7b As shown, the sound member 40 is provided with a protrusion 410 of a hollow structure, the protrusion 410 faces the washer ring 340, the protrusion 410 is inserted into the second annular groove 341, and a second space is defined between the protrusion 410 and the bottom of the second annular groove 341.

[0077] The depth of the first annular groove 211 is limited, so the hollow protrusion 410 provided on the sounding member 40 can not only increase the first space 4a, but also improve the connection firmness between the sounding member 40 and the washer ring 340, thereby improving the structural stability of the stapler. The increase in the first space 4a can make the air in the first space 4a vibrate more, thereby increasing the impact sound generated by the cutting knife 330 hitting the surface of the sounding member 40.

[0078] Of course, while the protrusion 410 is inserted into the second annular groove 341 to improve the structural stability of the stapler, a second space is provided between the protrusion 410 and the bottom of the second annular groove 341 , which enables the cutting knife 330 to have a sense of drop after cutting the gasket knife ring 340 .

[0079] Figure 4c The shape of the protrusion 410 shown in the figure is a square, and the shape of the protrusion 410 can also be an arc, a circle, etc., which is not specifically limited in the embodiment of the present application.

[0080] In an alternative embodiment, if Figure 4c and Figure 8As shown, the sound member 40 contacts the groove wall of the first ring groove 211 and forms a third ring groove 420 and a fourth ring groove 430 therewith, and the washer ring 340 matches the third ring groove 420 and the fourth ring groove 430 at the same time.

[0081] The protrusion 410 is located in the middle of the sound piece 40, and the two side edges of the sound piece 40 contact the groove wall of the first annular groove 211. The two side groove walls of the second annular groove 341 of the washer ring 340 are respectively inserted into the third annular groove 420 and the fourth annular groove 430 to improve the assembly stability of the first annular groove 211, the sound piece 40 and the washer ring 340, thereby improving the structural stability of the stapler.

[0082] The following are detailed operating steps of the stapler, including the following steps:

[0083] The first step is to use the adjustment member 60 to adjust the position of the nail support 20 relative to the shell 10, so that the position between the nail support 20 and the cutting knife 330 or the nail magazine 311 is in a firing position relationship, that is, a safe closed nail height distance.

[0084] Figure 4c Schematic diagram showing the relationship between the anvil 20 and the cutting knife 330 in a firing position, that is, in the axial direction of the shell 10, the foreskin a to be cut is located between the cutting knife 330 and the knife washer 340.

[0085] In the second step, the firing handle 510 fires and drives the firing push block 520 to push the push nail body 322 along the axis direction of the housing 10, that is, Figure 4a The cutting knife 330 connected to the push pin body 322 moves toward the gasket ring 340 in the direction of the arrow s1 shown in the figure, and cuts the foreskin and the gasket ring 340. The space between the gasket ring 340 and the sound piece 40 enables the doctor to feel the difference in touch, so as to prompt the doctor to complete the foreskin cutting.

[0086] Figure 9a FIG. 3 is a schematic diagram showing the state after the cutting knife 330 cuts the gasket ring 340 .

[0087] Step 3: After the cutting knife 330 has cut the gasket ring 340, it continues to move toward the distal end along the axis direction of the shell 10 and hits the surface of the sound piece 40 to produce a knocking sound to prompt the doctor to complete the circumcision action.

[0088] Figure 9b The schematic diagram of the structure of the cutting knife 330 hitting the surface of the sound member 40 is shown in FIG.

[0089] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations included in the claims. Various modifications and changes may be made on the basis of the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form other embodiments of the present application that may not be explicitly described. Therefore, the above embodiments only express several implementations of the present application and do not limit the scope of protection of the patent of this application.
