Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a foreskin fixation component and a foreskin cutting stapler. Background Technology

[0002] The circumcision stapler is a medical device specifically designed for circumcision surgery. It completes the cutting and suturing of the foreskin tissue with a single firing, and has the advantages of short operation time, smooth and beautiful incision, and simple operation.

[0003] Currently, existing circumcision staplers typically use a retaining ring to lock the foreskin tissue onto the glans penis via a snap-fit ​​mechanism. This helps to position the foreskin tissue on the glans, facilitating precise cutting of the foreskin tissue by the cutting tool and accurate staple placement. However, once the retaining ring has locked the foreskin tissue, adjusting its position is difficult due to the snap-fit ​​connection method. This requires the operator to use external forceps or other tools for unlocking. This process is not only cumbersome but also makes it difficult for the surgeon to operate due to the difficulty in maintaining a stable penile position during surgery, resulting in low adjustment efficiency and inconvenience, directly impacting the overall surgical efficiency. Summary of the Invention

[0004] In view of this, it is necessary to provide a foreskin fixation component and a foreskin cutting stapler for solving the above-mentioned technical problems.

[0005] A foreskin fixation component, used in a foreskin circumcision stapler, for locking foreskin tissue to the glans; the foreskin fixation component includes: A fixed ring body, comprising a first fixed body and a second fixed body hinged to each other, wherein the free end of the first fixed body is provided with a mounting part, and the free end of the second fixed body is provided with a connecting part, wherein the connecting part is capable of adjusting its position relative to the mounting part after passing through the mounting part. A locking element, which is slidably mounted within the mounting portion, and the locking element having a locking portion; The locking member has a locking position and an unlocking position. When the locking member is in the locking position, the locking part locks the connecting part; when the locking member is in the unlocking position, the locking part unlocks the connecting part.

[0006] Understandably, the locking mechanism between the locking part and the connecting part on the locking member secures the first and second fixation bodies, while the locking member is unlocked by sliding it. This allows the operator to control the locking and unlocking of the foreskin fixation component simply by pushing the locking member, thus facilitating the adjustment of the position of the first and second fixation bodies on the glans penis. This makes intraoperative adjustments simpler and more efficient, contributing to improved overall surgical efficiency.

[0007] In one embodiment, the locking part can engage with the connecting part to lock the connecting part to the mounting part and to secure the first fixing body to the second fixing body.

[0008] It is understandable that using a meshing method to lock the connecting part with the locking element can improve the firmness and anti-displacement ability of the locking element when locking the connecting part, thereby enhancing the locking stability between the first fixed body and the second fixed body; at the same time, this locking method also simplifies the mating structure between the locking element and the connecting part.

[0009] In one embodiment, the locking member is further provided with a through groove, and the connecting portion passes through the through groove; The locking part is disposed on the groove wall of the through groove.

[0010] In one embodiment, the locking element is disposed through the mounting portion.

[0011] Understandably, by setting the locking element through the mounting part, the portion of the locking element extending out of the mounting part can be used as a drive part for the operator to operate. The operator can control the locking element to slide within the mounting part by pushing the drive part with a single finger, thereby easily and quickly locking and unlocking the foreskin fixation component. This makes the adjustment of the foreskin fixation component during surgery more intuitive and convenient, thereby further improving the convenience of adjustment and the overall surgical efficiency.

[0012] In one embodiment, the locking member is further configured with a first limiting portion, which is disposed on the outside of the mounting portion; When the locking member is in the unlocked position, the first limiting part can abut against the mounting part for limiting.

[0013] Understandably, by using the first limiting part on the locking component to abut against the mounting part when it slides to the unlock position, on the one hand, it can provide the operator with a clear and definite unlocking endpoint, ensuring clear feel and controllable operation; on the other hand, it can reliably prevent the locking component from accidentally coming completely out of the mounting part, thereby avoiding interference and risks that may be caused by the separation of the locking component during the operation, effectively ensuring the continuity of operation and overall safety.

[0014] In one embodiment, the first limiting portion can abut against and limit the mounting portion in a face-to-face contact manner.

[0015] It is understandable that by using a surface-to-surface contact method to achieve the contact and limiting between the first limiting part and the mounting part, the stability of the locking part when it is limited in the unlocking position can be improved.

[0016] In one embodiment, the locking member is further configured with a second limiting portion; When the locking member is in the locked position, the second limiting part can abut against and limit the mounting part; and when the locking member is in the unlocked position, the second limiting part is housed within the mounting part.

[0017] Understandably, by using the second limiting part on the locking member, it is made to abut against the mounting part when it slides to the locking position. This provides a stable limiting force for locking the locking part and the connecting part, thereby ensuring the stability of the locking between the first and second fixed bodies. On the other hand, the damping force generated by the second limiting part being housed in the mounting part can be used to provide different operating feel and functional requirements when the locking member switches between the locking and unlocking positions.

[0018] In one embodiment, one of the locking member and the mounting part is provided with a groove, and the other is provided with a protruding rib, which can slide and engage with the groove.

[0019] In one embodiment, the first fixing body is further provided with a first arc-shaped protrusion, and the second fixing body is further provided with a second arc-shaped protrusion. When the locking member is in the locked position, the first arc-shaped protrusion aligns with the second arc-shaped protrusion to secure the foreskin tissue on the glans.

[0020] This application also provides a circumcision stapler, including the foreskin fixation component described above.

[0021] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The foreskin fixation component and foreskin cutting stapler claimed in this application achieve locking between the first and second fixation bodies through locking between the locking part and the connecting part on the locking member, and unlock it from the connecting part by sliding the locking member. This allows the operator to control the locking and unlocking of the foreskin fixation component simply by pushing the locking member, thereby conveniently adjusting the position of the first and second fixation bodies in holding and fixing the foreskin tissue on the glans, making intraoperative adjustments simpler and more efficient, and helping to improve the overall surgical efficiency.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or may have an intervening component.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] like Figure 8 , Figure 9 As shown, the foreskin fixing component 100 claimed in this application is used in a foreskin cutting stapler 1000 to lock the foreskin tissue (not shown) to the glans seat 200, so as to achieve precise positioning and fixing of the foreskin tissue on the glans seat 200. This ensures the neatness and regularity of the cutting line on the foreskin tissue, thereby providing a reliable operational basis for the subsequent cutting and anastomosis operations of the foreskin cutting stapler 1000.

[0038] like Figures 1 to 6As shown, the foreskin fixing assembly 100 provided in this application includes a fixing ring 10 and a locking member 20. The fixing ring 10 includes a first fixing body 11 and a second fixing body 12 hinged to each other. The free end of the first fixing body 11 has a mounting portion 111, and the free end of the second fixing body 12 has a connecting portion 121. The connecting portion 121 can be adjusted in position relative to the mounting portion 111 after passing through it. The locking member 20 is slidably installed in the mounting portion 111 and has a locking portion 21. The locking member 20 has a locked position and an unlocked position. When the locking member 20 is in the locked position, the locking portion 21 locks the connecting portion 121. When the locking member 20 is in the unlocked position, the locking portion 21 unlocks from the connecting portion 121. Here, the aforementioned free end specifically refers to the end of the corresponding first fixing body 11 and second fixing body 12 away from their hinge node, wherein the arc angle between the first fixing body 11 and the second fixing body 12 is 180°.

[0039] It should be noted that when the locking part 21 locks the connecting part 121, the locking member 20 can lock the connecting part 121 to the mounting part 111 through the locking part 21, thereby locking the second fixing body 12 to the first fixing body 11. At this time, the first fixing body 11 and the second fixing body 12 close together to form a complete ring structure, which is used to lock the foreskin tissue to the glans seat 200. For this purpose, the mounting part 111 can be integrated into the first fixing body 11 on the outside of the corresponding ring, and the connecting part 121 can be integrated into the second fixing body 12 on the outside of the corresponding ring. When the locking part 21 and the connecting part 121 are unlocked, the locking member 20 can release the lock on the connecting part 121 on the mounting part 111, and the first fixing body 11 and the second fixing body 12 can freely unfold around their hinge node, realizing the opening and closing function of the fixing ring body 10.

[0040] As can be seen from the above, the foreskin fixation assembly 100 of this application achieves the locking between the first fixation body 11 and the second fixation body 12 through the locking part 21 and the connecting part 121 on the locking member 20, and unlocks it from the connecting part 121 by sliding the locking member 20. This allows the operator to control the locking and unlocking of the foreskin fixation assembly 100 simply by pushing the locking member 20, thereby conveniently adjusting the clamping and fixation of the foreskin tissue by the first fixation body 11 and the second fixation body 12, making the intraoperative adjustment operation simpler and more efficient, and helping to improve the overall surgical efficiency.

[0041] like Figure 1 , Figure 3 and Figure 5As shown, in one embodiment, the first fixing body 11 is further constructed with a first arc-shaped protrusion 112, and the second fixing body 12 is further constructed with a second arc-shaped protrusion 122. When the locking member 20 is in the locked position, the first arc-shaped protrusion 112 and the second arc-shaped protrusion 122 engage to secure the foreskin tissue on the glans seat 200. In other words, the foreskin fixing component 100 of this embodiment can specifically achieve the securing of the foreskin tissue on the glans seat 200 through the interlocking of the annular protrusion formed by the engagement of the first arc-shaped protrusion 112 and the second arc-shaped protrusion 122 with the corresponding groove 201 on the glans seat 200. It should be noted that when the annular protrusion and the groove 201 engage, a gap of 0.3mm-1mm can be formed between them to meet the requirements for securing the foreskin tissue.

[0042] Here, the first arc-shaped protrusion 112 is located at the middle position in the thickness direction of the first fixing body 11, and can be integrated with the first fixing body 11. Of course, it is not limited to this. Those skilled in the art can also place the first arc-shaped protrusion 112 on any side of the first fixing body 11 in its thickness direction, or set the number of the first arc-shaped protrusion 112 to two or even more. The same design method also applies to the second arc-shaped protrusion 122 on the second fixing body 12. Its specific position can be adaptively adjusted according to design needs, which will not be elaborated here.

[0043] like Figure 2 As shown, in one embodiment, one of the locking member 20 and the mounting part 111 is constructed with a groove 22, and the other is constructed with a protruding rib 1111. The rib 1111 can slide and engage with the groove 22, thereby enabling the locking member 20 to slide on the mounting part 111.

[0044] Here, the rib 1111 is provided on the inner peripheral wall of the mounting part 111, and the rib 1111 can be connected to the mounting part 111 as a whole; correspondingly, the groove 22 is formed on the outer peripheral wall of the locking member 20, so that the sliding fit structure between the locking member 20 and the mounting part 111 does not occupy additional space. Of course, it is not limited to this. Those skilled in the art can also provide the rib on the locking member 20 and the groove on the inner peripheral wall of the mounting part 111, which will not be elaborated here.

[0045] like Figure 4 , Figure 6As shown, in one embodiment, the locking part 21 can mesh with the connecting part 121 to lock the connecting part 121 to the mounting part 111, and to lock the first fixing body 11 and the second fixing body 12 together. That is, in this embodiment, the locking member 20 uses a meshing engagement to lock the connecting part 121 that passes through the mounting part 111. By using a meshing locking method, the firmness and anti-displacement ability of the locking member 20 when locking the connecting part 121 can be improved, thereby enhancing the locking stability between the first fixing body 11 and the second fixing body 12. At the same time, this locking method also simplifies the cooperation structure between the locking member 20 and the connecting part 121.

[0046] Here, the connecting part 121 is configured as a rack structure integrated into the second fixing body 12, and the locking part 21 is a locking tooth structure integrated into the locking member 20. Of course, it is not limited to this. For those skilled in the art, the locking part 21 and the connecting part 121 can also be locked together by a concave-convex fit. Alternatively, the locking part can be configured as a pin integrated into the locking member 20, and the connecting part 121 can be provided with a plurality of holes in sequence along its arc direction. The locking part can lock onto the connecting part 121 that passes through the mounting part 111 by inserting the pin into one of the holes. This will not be elaborated on here.

[0047] like Figure 4 , Figure 6 As shown, in one embodiment, the locking member 20 is further configured with a through groove 23, and the connecting portion 121 is disposed through the through groove 23; wherein, the locking portion 21 is disposed on the groove wall of the through groove 23. This allows the locking member 20 to slide within the mounting portion 111, so that when the locking member 20 moves between the locked position and the unlocked position, the connecting portion 121 is always kept within the through groove 23, thereby enabling the locking portion 21 to stably engage or disengage with the connecting portion 121 as the locking member 20 slides, so as to satisfy the locking member 20 to precisely control the locking or unlocking between the first fixed body 11 and the second fixed body 12.

[0048] In one embodiment, the locking member 20 is disposed through the mounting portion 111, so that the part of the locking member 20 protruding from the mounting portion 111 can be used as a drive part for operation by the operator. The operator can control the locking member 20 to slide within the mounting portion 111 by pushing the drive part with a single finger, thereby easily and quickly locking and unlocking the foreskin fixation component 100. This makes the adjustment operation of the foreskin fixation component 100 during the operation more intuitive and convenient, thereby further improving the convenience of adjustment and the overall surgical efficiency.

[0049] like Figure 2As shown, the locking member 20 also has a first limiting part 24, which is located on the outside of the mounting part 111. When the locking member 20 is in the unlocked position, the first limiting part 24 can abut against the mounting part 111 to limit its movement, thereby ensuring that the locking member 20 is always limited within the mounting part 111. This provides the operator with a clear and definite unlocking endpoint, ensuring clear feel and controllable operation. On the other hand, it reliably prevents the locking member 20 from accidentally coming completely out of the mounting part 111, thus avoiding interference and risks that may occur during surgery due to the separation of the locking member 20, effectively ensuring the continuity of operation and overall safety.

[0050] Here, the first limiting part 24 can abut against the mounting part 111 in a face-to-face contact manner, thereby improving the stability of the locking member 20 when it is limited in the unlocked position.

[0051] The first limiting part 24 is disposed within the groove 22 of the locking member 20 and is integrally connected to the locking member 20. Specifically, the first limiting part 24 abuts against the protruding rib 1111 on the mounting part 111 to limit the contact between the locking member 20 and the locking member 20 when the locking member 20 is in the unlocked position, ensuring that the first limiting part 24 does not protrude outwards from the locking member 20 and maintaining the compact structure of the locking member 20. Of course, in other embodiments, the first limiting part 24 may also be disposed on other parts of the locking member 20 besides the groove 22, which will not be elaborated here.

[0052] like Figure 2 , Figure 6 As shown, in one embodiment, the locking member 20 is further provided with a second limiting portion 25; and when the locking member 20 is in the locked position, the second limiting portion 25 can abut against the mounting portion 111 for limiting; and when the locking member 20 is in the unlocked position, the second limiting portion 25 is housed within the mounting portion 111. This allows the locking member 20 to utilize its second limiting portion 25 to abut against the mounting portion 111 when sliding to the locked position. This provides a stable limiting force for locking the locking portion 21 and the connecting portion 121, thereby ensuring the stability of the lock between the first fixing body 11 and the second fixing body 12; on the other hand, the damping force generated by the second limiting portion 25 being housed within the mounting portion 111 can also be used to provide different operating feel and functional requirements when the locking member 20 switches between the locked and unlocked positions.

[0053] Here, the second limiting part 25 can abut against the mounting part 111 in a line-to-surface contact manner, so that the second limiting part 25 can provide a reliable limiting force to ensure that the locking member 20 is firmly in the locked position; when the operator applies a large pushing force to the locking member 20, the characteristics of the line-to-surface contact can be used to guide the second limiting part 25 to slide and be stored in the mounting part 111, so that the locking member 20 can be smoothly switched to the unlocked position. This takes into account the dual operational requirements of the foreskin fixation component 100 for locking stability and rapid forced unlocking during surgery.

[0054] like Figure 7 As shown, this application also provides a circumcision stapler 1000, which includes the foreskin fixing component 100 described above.

[0055] like Figures 7 to 10 As shown, in one embodiment, the circumcision stapler 1000 further includes a glans seat 200, which also includes a rod 220. The seat 210 has a receiving cavity 211 for accommodating the glans (not shown), and the seat 210 has a vent hole 212 at the bottom of the receiving cavity 211, which communicates with the receiving cavity 211. The rod 220 is connected to the seat 210 and has an exhaust channel 221, which communicates with the vent hole 212. Air in the receiving cavity 211 can be discharged outwards through the vent hole 212 and the exhaust channel 221 in sequence. This design ensures that the vent 212 remains unobstructed during the insertion of the glans penis into the receiving cavity 211 of the seat 210, allowing for the complete expulsion of air from the receiving cavity 211. This fundamentally avoids positive pressure interference caused by air retention in the receiving cavity 211, enabling the foreskin tissue to be easily and accurately adjusted and fixed to the preset cutting position. This not only shortens the time for foreskin tissue positioning during the operation but also ensures the accuracy of the subsequent circumferential cutting position of the foreskin tissue, thereby optimizing the surgical outcome.

[0056] like Figure 8 , Figure 10 As shown, in one embodiment, the center line of the vent 212 is located on the central axis of the seat 210. That is, in this embodiment, the vent 212 of the glans seat 200 is located at the center of the seat 210, which ensures that the glans inserted into the receiving cavity 211 will not block the vent 212.

[0057] In one embodiment, the seat 210 is configured as a transparent component. Specifically, the seat 210 can be a transparent structure made of engineering plastics such as acrylic or polycarbonate (PC). This allows the operator to directly observe the real-time position of the glans penis and frenulum within the receiving cavity 211, enabling the operator to intuitively and accurately adjust the direction and position of the frenulum. This not only simplifies the operation but also creates conditions for subsequently determining the foreskin tissue cutting line, thus helping to ensure the accuracy of the foreskin tissue cutting position.

[0058] like Figure 8 , Figure 10 As shown, in one embodiment, the seat 210 is provided with a connecting cylinder 213, which extends away from the accommodating cavity 211 and communicates with the vent hole 212; and the rod 220 is partially inserted into the connecting cylinder 213 and connected to the connecting cylinder 213. That is to say, in this embodiment, the rod 220 is directly inserted into the connecting cylinder 213 of the seat 210 to achieve automatic alignment and communication between the exhaust channel 221 inside the rod 220 and the vent hole 212 on the seat 210. This not only greatly simplifies the assembly process of the glans seat 200 and effectively improves production efficiency, but also enhances the sealing and reliability of the connection between the vent hole 212 and the exhaust channel 221, preventing leakage.

[0059] Here, the connecting cylinder 213 and the base 210 are connected as one unit, and the rod 220 and the connecting cylinder 213 can be connected by screws, adhesives, or other methods. Of course, this is not the only option; those skilled in the art can also use an insert injection molding method to mold the base 210 onto the rod 220, which will not be elaborated here.

[0060] like Figure 8 , Figure 10 As shown, in one embodiment, the exhaust channel 221 extends along the length of the rod 220 and penetrates the rod 220, and the exhaust channel 221 is coaxially arranged with the vent hole 212. This allows the air in the accommodating cavity 211 of the seat 210 to flow along the length of the rod 220 and be discharged outward after passing through the vent hole 212.

[0061] Preferably, the rod 220 is configured as a metal tube, which allows the rod 220 to be processed based on existing metal tubes. This ensures the overall structural strength and rigidity of the rod 220 to meet the pressure requirements during surgery, thus helping to ensure the accuracy and safety of the circumcision stapler 1000 during surgical operations. On the other hand, the metal tube material is easy to cut and shape using standardized machining methods, which helps to achieve efficient and large-scale production of the rod 220, thereby improving production efficiency while effectively controlling manufacturing costs.

[0062] In summary, when the operator uses the circumcision stapler 1000 to fix the foreskin tissue to be cut, the glans penis can first be received on the seat 210 of the glans penis seat 200, so that the foreskin tissue to be cut is fitted around the outer periphery of the seat 210. Subsequently, the first fixing body 11 and the second fixing body 12 of the foreskin fixing assembly 100 of this application are fitted together onto the foreskin tissue that has been tensioned by the seat 210 outside the seat 210, and the connecting part 121 of the second fixing body 12 is locked to the mounting part 111 of the first fixing body 11 by the locking member 20. During this process, the first arc-shaped protrusion 112 on the first fixing body 11 and the second arc-shaped protrusion 122 on the second fixing body 12 respectively form a concave-convex fit with the corresponding groove 201 on the seat 210, thereby firmly locking the foreskin tissue fitted around the seat 210, and achieving precise positioning and fixation of the cutting position.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
