Abstract
A device for clamping tissue includes a first jaw having a distal portion for communicating with tissue and a proximal portion having a first wing and a second wing. The device also includes a second jaw having a distal portion for communicating with tissue and a proximal portion having a first slot and a second slot, the first slot disposed between a middle structure and a first lateral structure, the second slot disposed between the middle structure and a second lateral structure. The first jaw is rotatably coupleable to the second jaw with the first wing extending into the first slot and the second wing extending into the second slot.
Claims23
A device for clamping tissue, comprising:
- a first jaw including:
- a distal portion adapted to communicate with tissue, and
- a proximal portion having a first wing and a second wing, wherein the first wing includes a first blind slot and the second wing includes a second blind slot, the first and second blind slots configured to receive opposite ends of an actuation shaft;
- and
- a second jaw including:
- a distal portion adapted to communicate with tissue, and
- a proximal portion having a first slot and a second slot, the first slot disposed between a middle structure and a first lateral structure, the second slot disposed between the middle structure and a second lateral structure, wherein the first jaw is rotatably coupleable to the second jaw with the first wing extending into the first slot and the second wing extending into the second slot.
A device for clamping tissue, comprising:
- a first jaw including:
- a first jaw body having a proximal portion and a distal clamping portion, and;
- a first bearing surface formed monolithically with the first jaw body as a single piece;
- and
- a first wing and a second wing, wherein the first wing includes a first blind slot and the second wing includes a second blind slot;
- a second jaw including:
- a second jaw body having a proximal portion and a distal clamping portion, and
- a second bearing surface formed monolithically with the second jaw body, the second jaw being rotatably coupleable to the first jaw such that the first bearing surface communicates with the second bearing surface at an interface;
- and
- a driver configured to rotate the first jaw with respect to the second jaw with the interface acting as a fulcrum and defining an axis of rotation between the first jaw and the second jaw, wherein the driver includes a shaft configured to extend into each of the first blind slot and the second blind slot.
