Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a circumcision stapler with convenient circumcision. Background Technology

[0002] The circumcision stapler (also known as a circumcision anastomosis device) is a medical device used for male circumcision surgery. Its working principle is to cut and suture the foreskin that is too long through a mechanical device. It has the advantages of short operation time, less bleeding, less pain, no need for manual suturing of the wound, neat incision, more regular suture points, and beautiful healing. It is suitable for cases such as phimosis and redundant foreskin.

[0003] Currently, the working principle of popular circumcision staplers on the market is to cut and suture the inner and outer layers of the foreskin using a mechanical device to achieve circumcision. The specific operation process of circumcision using a circumcision stapler is as follows: Before the operation, the patient is locally anesthetized. The doctor retracts the foreskin to expose the glans, places the glans cover of the circumcision stapler on the glans, pulls the excess foreskin around the outside of the glans cover, and secures the excess foreskin to the center bar at the rear end of the glans cover with suture using a purse-string closure. Then, the ring-shaped cutter head is placed in the appropriate position, and the mechanical device is activated for subsequent cutting and suturing operations. The existing circumcision staplers have the following problems: during the circumcision process, suture needs to be prepared separately, and the suture needs to be manually wrapped around the excess foreskin and the outside of the glans cover, and then knotted for fixation. The operating space is limited, and purse-string closure is difficult, seriously restricting the overall operation time of the circumcision surgery. Therefore, this utility model proposes a circumcision stapler with convenient purse-string closure to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a circumcision stapler with convenient purse-string tying. By pre-coaxially winding and laying the suture inside the staple cartridge cover, during the surgical procedure, after pulling the excessively long foreskin to the outside of the glans cover, only the two ends of the suture need to be pulled to achieve purse-string tying and fixation of the foreskin to the designated position of the rear center rod of the glans cover. Compared with the manual operation of additionally taking out and winding the suture for purse-string tying and fixation, this significantly reduces the difficulty of purse-string tying and fixation of the foreskin to the designated position of the rear center rod of the glans cover, and effectively shortens the overall operation time of circumcision surgery. The pre-coaxially winding and laying the suture inside the staple cartridge cover has good correspondence with the position to be purse-stringed, which helps to improve the quality of purse-string tying and greatly reduces the workload of doctors during surgery, making it highly practical.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a convenient circumcision stapler, comprising a glans cover, a staple cartridge, a staple cartridge sleeve, a transmission sleeve, a handle, a handle connector, a staple pusher sleeve, a return spring, an intermediate sleeve, an adjusting nut, and a ring cutter. The glans cover is fixed to the left end of a central rod. The central rod passes through the staple pusher sleeve, the transmission sleeve, the intermediate sleeve, and the adjusting nut sequentially from left to right. The staple cartridge is coaxially fixed to the left end of the staple cartridge sleeve. The ring cutter is coaxially injection molded and fixed to the inner side of the left end of the staple pusher sleeve. The staple cartridge sleeve is coaxially sleeved on the outer side of the staple pusher sleeve, and its right end is fixedly connected to the left end of the intermediate sleeve. The adjusting nut is screwed onto the threaded section at the right end of the center rod. The left end of the adjusting nut is inserted into and abuts against the right end of the intermediate sleeve. The right end of the tube body located at the right end of the push pin sleeve is fixedly connected to the transmission sleeve. The return spring is sleeved on the tube body and limited to the space between the staple cartridge sleeve and the transmission sleeve. The left end of the handle is hinged to the outside of the right end of the staple cartridge sleeve via a pin, and the middle part is hinged to the ear plate outside the transmission sleeve via a handle connector and a pin. The device also includes a staple cartridge cover sleeved and installed on the left end of the staple cartridge. A coaxial wire located on the outside of the left end of the staple cartridge is wound and laid on the inner side of the staple cartridge cover, and both ends of the wire extend to the outside of the left end of the staple cartridge cover.

[0006] This utility model discloses a convenient purse-string circumcision stapler. By pre-coaxially winding sutures inside the staple cartridge cover, during the surgical procedure, after pulling the excessive foreskin around the outside of the glans, only the two ends of the suture need to be pulled to achieve purse-string tying and fixation of the foreskin to the designated position on the rear center rod of the glans. Compared with the manual operation of additionally taking out and winding sutures for purse-string tying and fixation, this significantly reduces the difficulty of purse-string tying and fixation of the foreskin to the designated position on the rear center rod of the glans, effectively shortening the overall operation time of circumcision. The pre-coaxially winding sutures inside the staple cartridge cover correspond well to the required purse-string position, which helps to improve the quality of purse-string tying and greatly reduces the workload of the surgeon, making it highly practical.

[0007] A preferred technical solution is that the staple cartridge cover includes an annular base plate and an annular side plate vertically fixed to the outer periphery of the right side surface of the annular base plate. A plurality of locking blocks are fixedly arranged circumferentially on the right side surface of the annular base plate, and these locking blocks, together with the inner circumferential side surface of the annular side plate, form a plurality of wire-binding grooves with openings facing the right. The wire is wound and secured within these wire-binding grooves. The wire-binding groove structure is cleverly and reasonably designed. On the one hand, it ensures that the wire can be stably wound and bound within the plurality of wire-binding grooves arranged circumferentially on the inner side of the staple cartridge cover. On the other hand, it ensures that when the ends of the wire are pulled, the locking blocks deform under force, allowing the wire to smoothly disengage from the wire-binding grooves, thus achieving smooth operation when the foreskin and the glans cover are secured at a designated position using a purse-string closure.

[0008] A further preferred technical solution is that the outer side of the locking block is designed with an arc-shaped concave structure. On the one hand, this improves the locking stability of the wire harness groove for the wire, effectively preventing the wire wrapped inside the wire harness groove from coming out during equipment handling and transportation; on the other hand, it ensures that the locking block has good deformability, further ensuring that the locking block has good deformation under force when pulling the two ends of the wire, so that the wire can be smoothly released from inside the wire harness groove.

[0009] A further preferred technical solution includes a plurality of radially thin-walled grooves spaced circumferentially on the staple cartridge cover, and a plurality of pairs of lugs corresponding to the radially thin-walled grooves on the outer peripheral side of the staple cartridge cover. The two ends of the wire extend from the inner side of the same radially thin-walled groove to the outer left end of the staple cartridge cover. After the foreskin and glans are secured with a purse-string ties at the designated position on the rear center rod, the thin-walled grooves make the staple cartridge cover easy to tear off and remove, while the lugs improve the ease of gripping when tearing off the staple cartridge cover. The fact that the two ends of the wire extend from the inner side of the same radially thin-walled groove to the outer left end of the staple cartridge cover ensures ease of pulling the wire out of the staple cartridge cover and ease of knotting.

[0010] A further preferred technical solution is that the staple cartridge cover is an ABS injection molded part. The staple cartridge cover is simple to manufacture and process, highly efficient, and has good elastic deformation properties, further ensuring the smoothness of the staples disengaging from the cable tray when the clamps deform under force at both ends of the cable being pulled.

[0011] A further preferred technical solution is that the left end of the central rod has a binding section adjacent to the glans, and the outer peripheral side of the binding section is provided with several annular grooves. When the foreskin is bound to the designated position on the left end of the central rod with a purse-string closure, the suture is wound inside the corresponding annular groove, which helps to improve the binding and fixation firmness of the suture at the left end of the central rod, laying the foundation for the smooth performance of the subsequent circumcision surgery.

[0012] A further preferred technical solution is that a safety block is also snapped onto the left end of the outer side of the intermediate sleeve to abut against the staple cartridge sleeve and the transmission sleeve at intervals. The safety block serves as an anti-firing function, improving the safety of this circumcision stapler during production, packaging, transportation, and handling.

[0013] The advantages and beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a convenient purse-string circumcision stapler. By pre-coaxially winding and laying suture inside the staple cartridge cover, during the surgical procedure, after pulling the excessive foreskin to the outside of the glans cover, only the two ends of the suture need to be pulled to achieve purse-string tying and fixation of the foreskin to the designated position of the rear center rod of the glans cover. Compared with the manual operation of additionally taking out and winding suture for purse-string tying and fixation, it significantly reduces the difficulty of purse-string tying and fixation of the foreskin to the designated position of the rear center rod of the glans cover, and effectively shortens the overall operation time of circumcision surgery. The pre-coaxially winding and laying suture inside the staple cartridge cover has good correspondence with the position to be purse-stringed, which helps to improve the quality of purse-string tying and greatly reduces the workload of doctors during surgery, making it highly practical.

[0015] 2. The staple cartridge cover includes an annular base plate and an annular side plate vertically fixed to the outer periphery of the right side surface of the annular base plate. A plurality of locking blocks are fixedly arranged circumferentially on the right side surface of the annular base plate, and these locking blocks, together with the inner circumferential side surface of the annular side plate, form a plurality of wire-binding grooves with openings facing the right. The wire is wound and secured within these wire-binding grooves. The wire-binding groove structure is cleverly and reasonably designed. On the one hand, it ensures that the wire can be stably wound and bound within the plurality of wire-binding grooves arranged circumferentially on the inner side of the staple cartridge cover. On the other hand, it ensures that when the ends of the wire are pulled, the locking blocks deform under force, and the wire can be smoothly dislodged from the wire-binding grooves, thereby achieving smooth operation when the foreskin and the glans cover are secured at a designated position using a purse-string closure.

[0016] 3. The outer side of the locking block is designed with an arc-shaped concave structure. On the one hand, this improves the locking stability of the wire harness groove for the wire, effectively preventing the wire wrapped inside the wire harness groove from coming out during equipment handling and transportation; on the other hand, it ensures that the locking block has good deformability, further ensuring that the locking block has good deformation under force when pulling the two ends of the wire, so that the wire can be smoothly released from inside the wire harness groove.

[0017] 4. The staple cartridge cover is provided with several radially thin-walled grooves spaced circumferentially. The outer circumferential side of the staple cartridge cover is also provided with several pairs of lugs corresponding to the two sides of the radially thin-walled grooves. Both ends of the wire extend from the inner side of the same radially thin-walled groove to the outer left end of the staple cartridge cover. After the foreskin and glans are secured with a purse-string ties at the designated position on the rear center rod, the thin-walled grooves make the staple cartridge cover easy to tear off and remove, while the lugs improve the ease of gripping when tearing the staple cartridge cover. The fact that both ends of the wire extend from the inner side of the same radially thin-walled groove to the outer left end of the staple cartridge cover ensures ease of pulling the wire out of the staple cartridge cover and ease of knotting.

[0018] 5. The staple cartridge cover is an ABS injection molded part. The staple cartridge cover is simple to manufacture and process, highly efficient, and has good elastic deformation properties, further ensuring the smoothness of the staple cable disengaging from the cable tray groove when the clamping blocks deform under force when pulling the ends of the cable.

[0019] 6. The left end of the central rod has a binding section adjacent to the glans, and the outer peripheral side of the binding section is provided with several annular grooves. When the foreskin is bound to the designated position on the left end of the central rod with a purse-string closure, the suture is wound inside the corresponding annular groove, which helps to improve the binding and fixation of the suture at the left end of the central rod, laying the foundation for the smooth performance of the subsequent circumcision surgery.

[0020] 7. A safety block is also snapped onto the left side of the outer side of the intermediate sleeve to keep the staple cartridge sleeve and the transmission sleeve abutting apart. The safety block serves to prevent firing, improving the safety of this circumcision stapler during production, packaging, transportation, and handling. Attached Figure Description

Under the action of the return spring 11, the handle connector 9 drives the transmission sleeve 7, the pusher sleeve 10, and the annular cutter 14 back into the staple cartridge sleeve 6, completing the circumcision suture surgery.

[0041] This utility model discloses a convenient purse-string circumcision stapler. By pre-coaxially winding sutures inside the staple cartridge cover, during the surgical procedure, after pulling the excessive foreskin around the outside of the glans, only the two ends of the suture need to be pulled to achieve purse-string tying and fixation of the foreskin to the designated position on the rear center rod of the glans. Compared with the manual operation of additionally taking out and winding sutures for purse-string tying and fixation, this significantly reduces the difficulty of purse-string tying and fixation of the foreskin to the designated position on the rear center rod of the glans, effectively shortening the overall operation time of circumcision. The pre-coaxially winding sutures inside the staple cartridge cover correspond well to the required purse-string position, which helps to improve the quality of purse-string tying and greatly reduces the workload of the surgeon, making it highly practical.

[0042] The above description is only a preferred embodiment of the present utility model.
