Abstract
A hub assembly for use with an endoscopic assembly of a reposable surgical clip applier includes an outer housing and a drive assembly supported within the outer housing. The drive assembly includes a cartridge cylinder slidably supported within the outer housing, a plunger translatably supported within the outer housing and slidably coupled to the cartridge cylinder, a first biasing element interposed between the cartridge cylinder and the outer housing, and a second biasing element interposed between the cartridge cylinder and the plunger. The first biasing element includes a first threshold and the second biasing element includes a second threshold that is greater than the first threshold. A force exceeding the first threshold causes the cartridge cylinder and plunger to translate simultaneously and a force exceeding the second threshold causes the cartridge cylinder to translate relative to the plunger.
