ENDOSCOPIC SURGICAL CLIP APPLIER
First Claim
1. An endoscopic surgical clip applier, comprising:
- an endoscopic assembly including;
a shaft assembly; and
a pair of jaw members operatively coupled to, and extending from the shaft assembly; and
a handle assembly including;
a housing selectively connectable to the endoscopic assembly;
a fixed handle extending from the housing;
a trigger pivotally connected to the fixed handle;
a drive bar disposed within the housing of the handle assembly and operatively coupled to the trigger and the pair of jaw members to move the pair of jaw members between a spaced apart configuration and an approximated configuration upon actuation of the trigger;
a ratchet assembly disposed within the housing of the handle assembly, the ratchet assembly including;
a first rack operatively coupled to the drive bar, the first rack defining a plurality of first rack teeth and having a distal end and a proximal end, wherein the first rack includes a first length between the distal end and the proximal end thereof; and
a second rack operatively coupled to the drive bar, spaced apart from the first rack, the second rack defining a plurality of second rack teeth and having a distal end and a proximal end, wherein the second rack includes a second length between the distal end and the proximal end thereof, the second length of the second rack being less than the first length of the first rack.

Abstract
An endoscopic surgical clip applier includes an endoscopic assembly and a handle assembly. The endoscopic assembly includes a shaft assembly and a pair of jaw members. The handle assembly includes a housing, a fixed handle, a trigger, a drive bar, and a ratchet assembly. The ratchet assembly includes a first rack operatively coupled to the drive bar, the first rack defining a plurality of first rack teeth, wherein the first rack includes a first length between a distal end and a proximal end thereof, and a second rack operatively coupled to the drive bar, spaced apart from the first rack, the second rack defining a plurality of second rack teeth, wherein the second rack includes a second length between a distal end and a proximal end thereof, the second length of the second rack being less than the first length of the first rack.
