Abstract
A ligation clip remover removes closed ligation clips from a ligated vessel. The remover includes a handle assembly having a squeezable trigger and a slender barrel assembly connected to the handle assembly. A clip separating mechanism is connected to a distal end of the barrel assembly, and a shaft is slidably disposed in the barrel assembly for operating the clip separating mechanism when the trigger is squeezed.
Claims30
A ligation clip remover, comprising:
- a handle assembly with a squeezable trigger;
- a barrel assembly rotatably connected to said handle assembly, with said barrel assembly including a stationary portion at its distal end for receiving a ligation clip;
- a shaft slidably housed in said barrel assembly and slidable by actuation of said trigger;
- and
- a clip separator engaged to a distal portion of said barrel assembly, said separator having a lever pivotably mounted in said barrel assembly, wherein said separator is actuated by said sliding shaft to move a distal end of said lever toward said stationary portion of said barrel assembly.
