Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a circumcision stapler. Background Art

[0002] There are currently three common methods for clinical circumcision and suturing, including: not using a stapler, using a disposable circumcision device (commercial ring), and using a disposable circumcision stapler (also known as a circumcision stapler). Compared with the first two methods, the disposable circumcision stapler is easier to operate, and can complete the cutting and suturing of the foreskin at the same time in one operation. At the same time, compared with the other two circumcision and suturing methods, the use of a circumcision stapler does not require manual suturing of the wound, the incision is smoother, the suture points are more regular, and it is more beautiful after healing.

[0003] At present, the rear end of the annular cutter of the circumcision stapler on the market is mostly directly injection-molded and fixed to the front end of the staple pusher sleeve. The inner cavity hole of the stapler for placing the staples on the stapler is mostly a closed annular structure that passes through the front and rear end surfaces thereof. Moreover, after the stapler and the staple pusher sleeve are assembled, the gap between the outer wall surface of the inner cavity hole of the stapler close to the annular cutter and the outer surface of the annular cutter is about 0.3 to 0.4 mm. This results in a thin-walled structure for the injection-molded stapler mold. The scrap rate of the thin-walled mold is high during use, which seriously restricts the injection molding efficiency of the circumcision stapler and increases the mold investment cost. Summary of the invention
