Benefits of technology

[0011]In embodiments, the clip follower may include a window formed in a body portion thereof. Upon the at least one handle being further actuated, the distal end of the pusher tip is disposed within the window of the clip follower. The clip follower may be disposed within a distal end of clip channel and a down force of at least one resilient tang of the clip carrier facilitates retaining the clip follower at the distal end of the clip channel.

Problems solved by technology

However, in certain situations, when the same surgical clip applier is mistakenly used after the last clip has been applied, the jaw members of the surgical clip applier may unwantedly grasp body tissue at the surgical site.
As a result, the body tissue may be damaged, which sometimes causes trauma to the patient.
