First Claim
Patent Images
1. A reposable surgical clip applier, comprising:
- a handle assembly including;
a housing defining a bore therein and which extends through a distal end thereof;
a fixed handle extending from the housing;
a trigger pivotally connected to the fixed handle, the trigger including an actuating end disposed within the bore of the housing;
a drive plunger slidably supported within the bore of the housing and axially aligned with the bore of the housing, the drive plunger having a proximal end operatively engaged by the actuating end of the trigger, and a free distal end; and
a release lever supported on the housing, wherein the release lever includes a catch for engaging and securing an endoscopic assembly that is selectively connected to the handle assembly; and
a first endoscopic assembly selectively connectable to the housing of the handle assembly, via the catch of the release lever, the first endoscopic assembly including;
a shaft assembly having;
an outer tube defining a lumen therethrough, the outer tube including a proximal end and a distal end;
a pair of jaws pivotably and fixedly supported in, and extending from the distal end of the outer tube; and
an inner shaft slidably supported within the lumen of the outer tube, the inner shaft including a proximal end and a distal end, the distal end of the inner shaft being operatively engaged with the pair of jaws to effectuate an opening and a closing of the pair of jaws upon an axial translation of the inner shaft relative to the outer tube; and
a hub assembly configured for selective insertion in the bore of the housing of the handle assembly, the hub assembly including;
an outer housing supported on the proximal end of the outer tube, the outer housing defining an open proximal end; and
a drive assembly supported within the outer housing of the hub assembly, the drive assembly including;
a cartridge cylinder slidably supported in the outer housing of the hub assembly, the cartridge cylinder including a proximal end wall, an open distal end, and a bore therein;
a cartridge plunger supported on the proximal end of the inner shaft of the shaft assembly, the cartridge plunger being slidably supported in the bore of the cartridge cylinder;
a first biasing member disposed within the bore of the cartridge cylinder, and being interposed between the proximal end wall of the cartridge cylinder and the cartridge plunger; and
a second biasing member interposed between a proximal end of the outer tube of the shaft assembly and the cartridge plunger.
