FUSING AND CUTTING SURGICAL INSTRUMENT AND RELATED METHODS

摘要

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. An end effector having jaws may be supported by the wrist. The surgical instrument can further include 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 component of the end effector in a longitudinal direction relative to the jaws. The component can be configured to translate independently of movement of the jaws.

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; 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 component of the end effector in a longitudinal direction relative to the jaws, wherein the component is configured to translate independently of movement of the jaws.
