Abstract

The present disclosure provides a surgical device, comprising: a jaw assembly defining a first longitudinal axis and including a first jaw and a second jaw moveable relative to the first jaw; an elongated body defining a second longitudinal axis and coupled to a proximal end of the jaw assembly, wherein the jaw assembly is configured to articulate about an articulation axis transverse to the second longitudinal axis relative to the elongated body; a handle assembly coupled to a proximal end of the elongated body and comprising at least one motor mechanically coupled to the jaw assembly; and a control assembly coupled to the handle assembly, the control assembly including a first control button, a second control button, a first rocker device disposed about the first control button and configured to rotate thereabout, and a second rocker device disposed about the second control button and configured to rotate thereabout.

Claims

1. A surgical device, comprising:

a jaw assembly defining a first longitudinal axis and including a first jaw and a second jaw moveable relative to the first jaw;

an elongated body defining a second longitudinal axis and coupled to a proximal end of the jaw assembly, wherein the jaw assembly is configured to articulate about an articulation axis transverse to the second longitudinal axis relative to the elongated body;

a handle assembly coupled to a proximal end of the elongated body and comprising at least one motor mechanically coupled to the jaw assembly; and

a control assembly coupled to the handle assembly, the control assembly including;

a first control button;

a second control button;

a first rocker device defining a first aperture therethrough configured to receive a portion of the first control button therein; and

a second rocker device defining a second aperture therethrough configured to receive a portion of the second control button therein,

wherein the first and second rocker devices are rotatably supported on the first and second control buttons, respectively.

2. The surgical device according to claim 1, wherein actuation of the first control button moves the second jaw in approximation relative to the first jaw and actuating the second control button moves the second jaw away from the first jaw.

3. The surgical device according to claim 1, wherein actuation of the first rocker device is configured to articulate the jaw assembly about the articulation axis.

4. The surgical device according to claim 1, wherein actuation of the second rocker device is configured to rotate the jaw assembly about the second longitudinal axis relative to the elongated body.

5. The surgical device according to claim 1, wherein the first control button includes a first magnetic element, the second control button includes a second magnetic element, the first rocker device includes third and fourth magnetic elements, and the second rocker device includes fifth and sixth magnetic elements.

6. The surgical device according to claim 5, wherein the handle assembly comprises a plurality of sensors configured to detect proximity of the first, second, third, fourth, fifth, and sixth magnetic elements.

7. The surgical device according to claim 6, wherein the control assembly comprises a magnetic shield having a plurality of openings aligned with the plurality of sensors, the magnetic shield configured to shield the third, fourth, fifth, and sixth magnetic elements from respective sensors until the first and second rocker devices are actuated.
