The method according to the present invention can automatically identify, label, and retain important segments in a surgical video, and eliminate unimportant segments, so as to automatically obtain a surgical video on which different amounts of clipping can be performed according to a user's choice.
The present invention provides a surgical stapler. The surgical stapler includes an anvil portion, the anvil portion including a cap portion at one end of an anvil portion body, and a retaining pin recess of the anvil portion being offset to one side relative to a center line. An extension section of the cap portion provides a part of a tissue contacting surface of the anvil portion or is used for supporting a widened tissue contacting surface. This configuration allows as much as possible for a certain error when firing a retaining pin, so that even if the retaining pin is not accurately received by the retaining pin recess, an end portion of the retaining pin will abut against the tissue contacting surface of the anvil portion without missing the anvil portion and entering tissue. The retaining pin abuts against the enlarged tissue contacting surface, thereby resisting actuation of the anvil portion and a staple cartridge toward a closed configuration, which can enable an operator to perceive abnormal actuation of a guide pin. In addition, the retaining pin abutting against the tissue contacting surface of the anvil portion may be returned to the retaining pin recess with subsequent slight shaking or a similar operation, to allow for subsequent surgical procedures.
