US 2026/0263080 A1 · DEVICES, SYSTEM AND METHODS FOR APPLYING MULTIPLE CLIPS TO TISSUE

Abstract

A surgical instrument for applying surgical clips to tissue comprises a shaft comprising a proximal end and a distal end, a wrist mechanism coupled to the distal end of the shaft and configured to articulate relative to the shaft in one or more degrees of freedom and an end effector supported by the wrist mechanism. The end effector comprises a pair of opposing jaw members configured to move relative to each other between open and closed positions. A path configured to receive and permit advancement of a medical clip into engagement with the jaw members is defined through the wrist mechanism and end effector. The instrument allows a surgeon, for example, to deliver one or more surgical clips onto tissue or vessels without having to exchange the instrument or to change the orientation of the jaws during clip advancement, which reduces disruption to the surgeon's workflow.

Dependent claims

A surgical instrument for applying surgical clips to tissue, the instrument comprising:

an elongate shaft having a longitudinal axis;
an end effector on a distal end of the shaft including a first jaw and a second jaw;
an articulation assembly coupling the end effector to the shaft, the articulation assembly comprising a pulley rotatable about an axis substantially perpendicular to the longitudinal axis and a cable extending around at least a portion of the pulley, the cable coupled to the first and second jaws and configured to move at least one of the first and second jaws between an open position and a closed position;
and
a drive member configured to translate longitudinal through the articulation assembly to deliver a surgical clip to the first and second jaws.

A surgical instrument for applying surgical clips to tissue, the instrument comprising:

an elongate shaft having a longitudinal axis;
an end effector on a distal end of the shaft including a pair of opposing jaws including a first jaw and a second jaw;
an internal channel extending at least from the elongate shaft to the end effector;
a wrist assembly coupling the end effector to the shaft, wherein the wrist assembly comprises:
a first articulation mechanism peripheral to the internal channel and configured to rotate the end effector about a first axis substantially perpendicular to the longitudinal axis;
a second articulation mechanism peripheral to the internal channel and configured to rotate the end effector about a second axis perpendicular to the first axis and the longitudinal axis;
and
a drive member configured to translate longitudinal through the internal channel of the wrist assembly to deliver a surgical clip to the first and second jaws.
