Abstract

A surgical device has a jaw assembly with a first jaw and a second jaw, a pivoting linkage, and a camming assembly configured to pivot the jaw assembly. A cam slot having a first portion, a second portion, and a third portion may have a Y shaped configuration. A flexible shaft allows further pivoting of the jaw assembly.

Claims

1. A surgical device, comprising:

a jaw assembly comprising;

a first jaw and a second jaw moveable relative to the first jaw; and

a drive screw configured to move the second jaw relative to the first jaw;

a pivoting linkage coupled to the proximal end of the jaw assembly, the pivoting linkage comprising a distal joint member and a proximal joint member, wherein the jaw assembly and the distal joint member define a first longitudinal axis extending between a proximal end of the jaw assembly and a distal end of the distal joint member, and the proximal joint member defines a second longitudinal axis; and

a camming assembly coupled to the distal and proximal joint members, the camming assembly configured to pivot the jaw assembly relative to the proximal joint member about a pivot axis that is perpendicular to the first and second longitudinal axes from an aligned configuration in which the first and second longitudinal axes are substantially parallel to each other into a pivoted configuration in which the first and second longitudinal axes are substantially perpendicular to each other.

2. The surgical device of claim 1, further comprising:

a drive shaft disposed within the pivoting linkage, the drive shaft configured to engage the drive screw and rotate in a first direction to move the second jaw relative to the first jaw when the jaw assembly is in one of the aligned configuration and the pivoted configuration.

3. The surgical device of claim 2, wherein in the aligned configuration the drive shaft is configured to engage the drive screw directly.

4. The surgical device of claim 3, wherein the pivoting linkage further comprises:

a secondary gearing assembly comprising;

a secondary first gear coupled to the primary first gear, the secondary first gear configured to rotate the jaw assembly about the first longitudinal axis when the jaw assembly and the distal joint member are in a pivoted configuration; and

a secondary second gear coupled to the primary second gear, the secondary second gear configured to move the second jaw relative to the first jaw.

5. The surgical device of claim 4, wherein in the pivoted configuration the drive shaft is configured to engage the drive screw through the secondary second gear.

6. The surgical device of claim 2, wherein the pivoting linkage further comprises:

a primary gearing assembly comprising;

a primary first gear coupled to the jaw assembly configured to rotate the jaw assembly about the first longitudinal axis; and

a primary second gear coupled to the drive screw configured to move the second jaw relative to the first jaw.
