Apparatus and methods for surgical stapler clamping and deployment

摘要

A surgical stapling apparatus configured to perform stapling and/or cutting operations on a target tissue of a patient. The surgical stapling apparatus comprises of a mode selection switch to place the apparatus in either a clamping operational phase or a deployment operational phase. In the clamping operational phase, various clamp components are operated to facilitate loading of surgical staples into the stapling apparatus, if not preloaded, placement of the stapling apparatus to a target surgical site, and clamping of target tissue to be stapled and/or cut. In the deployment operational phase, various deployment components are operated to staple and/or cut the target tissue to one or more desired distance intervals to achieve the desired outcome for the surgical procedure.

1. A surgical stapling apparatus, comprising:
an end effector comprising
a staple holder,a plurality of staples held within the staple holder, andan anvil pivotally connected to the staple holder; at least one clamp gear; a clamp mechanism coupled to the at least one clamp gear and to the end effector; at least one deployment gear; a deployment mechanism coupled to the at least one deployment gear and to the end effector; a single trigger operable to clamp the end effector and also to deploy staples therefrom; and a mode switch mechanism coupled to the single trigger; wherein the mode switch mechanism is selectively engageable with one of the clamp gear and the deployment gear, such that when the mode switch mechanism engages the clamp gear, actuation of the single trigger clamps the end effector, and when the mode switch mechanism engages the deployment gear, actuation of the single trigger deploys the staples from the end effector.
