Title: CIRCUMCISION STAPLER
Abstract:
A circumcision stapler. An internal positioning device (44) on a stapler base (4), and outer positioning device (5) of the stapler are used to engage and position a foreskin. A surgeon can hold the stapler base (4) with one hand and use the other hand to rotate the foreskin and observe the location of the frenum and to position, adjust the frenum, and prevent the frenum from entering the circumcision area; push a ring-shaped blade (1) to circumcise the foreskin, then push a staple pushing body (2) to push a staple (6) towards a staple slot (43); when the staple (6) is fixed on the foreskin, insert the staple (6) onto one side of the washer (7), the side of the washer (7) with the staple (6) provides secure positioning, while the other side can be flipped to correspond to a penis erection, reducing pressure between the staple (6) and the skin, wherein the asymmetric washer (7) allows the staple (6) to be closer to the incision site, while the prying action of the leveraging force of the single side of the washer (7) distal from the incision site allows a staple (6) to be more easily cut and ejected from the edge of the incision site. After incision stapling is complete, the state of the staple (6) at the incision site can be observed without disengaging the outer positioning device (5). Disengagement is performed after ensuring all of the staples (6) are securely fixed. In case of insecure stapling, remedial stapling can be performed before disengagement to avoid the risk of bleeding during surgery.
