Abstract

A self-contained powered surgical clip applier is provided which includes an elongate body defining a longitudinal axis and housing a plurality of surgical clips. The powered clip applier further includes a jaw assembly operatively associated with a distal end of the elongate body and actuable to move between an open position and a closed position, a motor assembly disposed within the elongate body, a power supply positioned within the elongate body for energizing the motor assembly, a clip pusher configured to individually advance surgical clips into the jaw assembly, and an actuation channel driven by the motor assembly and configured to translate through the elongate body to drive the clip pusher and actuate the jaw assembly.

Dependent claims

A self-contained powered surgical apparatus for applying surgical clips to body tissue comprising:

a) an elongate body having an internal cavity formed therein, defining a longitudinal axis and housing a plurality of surgical clips;
b) a jaw assembly supported at a distal end portion of the elongate body and including a pair of opposed cooperating jaw members actuable to move between an open position and a closed position with respect to the longitudinal axis of the body;
c) an electric motor assembly mounted within the internal cavity of the elongate body;
d) a clip pusher slidably supported in the elongate body adjacent the plurality of surgical clips and actuable to individually advance the surgical clips into the jaw assembly;
e) an elongate actuation mechanism disposed within the elongate body, driven by the motor assembly, and mounted to translate longitudinally through the elongate body upon actuation of the motor assembly to drive the clip pusher and actuate the jaw assembly;
and
f) an electrical power source disposed within the internal cavity of the elongate body and electrically connected to the motor assembly for energizing the motor assembly to drive the actuation mechanism.

A self-contained powered surgical apparatus for applying surgical clips to body tissue comprising:

a) an elongate body having an internal cavity formed therein, defining a longitudinal axis, and housing a plurality of surgical clips;
b) a pair of jaws extending from a distal end portion of the elongate body, the jaws being relatively moveable between open and closed positions and supporting a surgical clip advanced therebetween;
c) clip advancing means movably supported within the elongate body adjacent the plurality of surgical clips for individually advancing the surgical clips into the pair of jaws;
d) jaw moving means disposed within the elongate body and mounted to translate relative to the jaws for moving the jaws between open and closed positions;
f) an electric motor assembly disposed within the internal cavity of the elongate body and operatively connected to the clip advancing means and the jaw moving means for translating the clip advancing means to feed a clip into the jaws and for actuating the jaw moving means to open and close the jaws;
g) control means positioned on the elongate body and electrically connected to the motor assembly for selectively actuating the motor assembly;
and
h) means disposed within the internal cavity of the elongate body and electrically connected to the motor assembly for energizing the motor assembly.
