- attaching a surgical device to a distal tip of a surgical instrument, the surgical instrument including:
- a body having an outer housing and a handle, the outer housing having a longitudinal body with a channel extending therethrough and a distal tip configured to engage the surgical device;
- a shaft including a release shaft having a distal end configured to contact the surgical device and a second end, the shaft being housed within the channel of the outer housing, the shaft including a rack having a longitudinal body with a plurality of teeth;
- a pinion having a plurality of teeth radially extending therefrom and configured to mate with the plurality of teeth of the rack, and a cam having a generally circular body with at least one projection which is rotatably attached to the pinion and the body;
- and
- a trigger coupled to the handle and a linkage connecting the trigger to the second end of the shaft, and
