Fusing and cutting surgical instrument and related methods
First Claim
1. A surgical instrument comprising:
- a shaft having a proximal end and a distal end;
a wrist coupled to the distal end of the shaft and configured to articulate in multiple degrees of freedom; and
an end effector supported by the wrist, wherein the end effector comprises a cutting element and jaws configured to grip tissue and fuse tissue, and wherein the cutting element is configured to translate along a longitudinal direction of the jaws.

Abstract
A surgical instrument can include a shaft having a proximal end and a distal end, and a wrist coupled to the distal end of the shaft and configured to articulate in multiple degrees of freedom coupled to the distal end of the shaft. The surgical instrument can further include an end effector supported by the wrist, wherein the end effector includes a cutting element and jaws configured to grip tissue and fuse tissue via electrosurgical energy. The surgical instrument can be configured for use with a teleoperated robotic surgical system that can include a patient side console configured to interface to actuate the surgical instrument and a surgeon side console configured to receive inputs from a surgeon to control the actuation of the surgical instrument.

25. A method of operating a surgical instrument, the method comprising:
-
receiving at least one first input at a transmission mechanism disposed at a proximal portion of the surgical instrument to articulate a multiple degree-of-freedom articulable wrist of the surgical instrument in at least one of pitch and yaw; transmitting one or more forces via the transmission mechanism to articulate the wrist in response to the first input; receiving a second input at the transmission mechanism to open jaws of an end effector supported by the wrist; transmitting torque via the transmission mechanism to a torque drive component to open the jaws; receiving a third input at the transmission mechanism to close the jaws of the end effector; transmitting torque via the transmission mechanism to the torque drive component to close the jaws to grip tissue between the jaws; transmitting energy to the jaws to fuse the gripped tissue; receiving a fourth input at the transmission mechanism to translate a cutting element of the end effector; and transmitting a force to a cutting element drive component via the transmission mechanism to translate the cutting element along a longitudinal direction of the jaws of the end effector. - View Dependent Claims (26, 27, 28, 29)

32. A surgical instrument comprising:
-
a shaft having a proximal end and a distal end; a wrist coupled to the distal end of the shaft and configured to articulate in multiple degrees of freedom; an end effector supported by the wrist, the end effector comprising jaws; a first drive element extending from the proximal end of the shaft to the end effector, the first drive element being configured to transmit forces to move the jaws relative to each other between open and closed positions; and a second drive element extending from the proximal end of the shaft to the end effector, the second drive element being configured to transmit forces to translate a cutting component of the end effector in a longitudinal direction relative to the jaws, wherein the cutting component is configured to translate independently of movement of the jaws.
