摘要:
A surgical device includes a handle assembly and a firing counter assembly. The handle assembly includes a housing defining a window, a trigger, and a drive member axially movable within the housing and operatively coupled with the trigger. The firing counter assembly includes a camming pin and a sleeve rotatably supported about the drive member and defining a continuous groove. The sleeve has indicia circumferentially arranged about the sleeve and corresponding to the number of surgical clips in the surgical device. The camming pin is supported on the drive member for concomitant axial displacement with the drive member. The camming pin is configured to slide through the continuous groove of the sleeve, wherein actuation of the trigger causes rotation of the sleeve such that the indicia corresponding to the number of surgical clips remaining in the surgical device is shown through the window of the housing.
