CUTTING MECHANISMS FOR SURGICAL END EFFECTOR ASSEMBLIES, INSTRUMENTS, AND SYSTEMS

A surgical system includes an attaching device having an end effector disposed at the distal end thereof. The end effector includes a support member, a wrist pivot pivotably coupling the end effector to the attaching device, and first and second jaw members pivotably coupled to one another and the support member. A first cable is operably coupled to the wrist pivot and configured to articulate the end effector relative to the attaching device. Second and third cables are operably coupled to the jaw members and configured to pivot the jaw members relative to the support member. A first actuation of the second and third cables collectively pivots the first and second jaw members relative to the support member. A second actuation of the second and third cables pivots the first and second jaw members relative to one another and the support member between a spaced-apart position and an approximated position.

Surgical instrument with jaw alignment features

A surgical instrument that includes first and second jaws that are movably coupled together to move between an open and a closed position. The first jaw includes a first proximal end, a first distal tip, and a first jaw midpoint between the first proximal end and the first distal tip. The second jaw includes a second proximal end and a second distal tip. The first jaw includes a first alignment feature that is distal to the first jaw midpoint and is configured to engage a corresponding portion of the second jaw when the first and second jaws are moved to the closed position to align the first distal tip with the second distal tip.

SURGICAL CLIP APPLIER WITH PARALLEL CLOSURE JAWS

An end effector for a surgical clip applier includes a housing, jaws that include opposed first and second jaw members, each comprising an independent structure movable relative to the other, the first jaw member defining a first inner surface and the second jaw member defining a second inner surface opposite the first inner surface, and an actuation mechanism arranged within the housing and operable to move the jaws between open and closed positions. The actuation mechanism includes an actuation plate longitudinally movable within the housing, and a transition pin extending from the actuation plate and received within corresponding slots defined in each jaw member. Linear movement of the actuation plate drives the transition pin through the corresponding slots and thereby moves the jaws between the open and closed positions.

A system comprises a medical instrument including a rotatable capstan. The rotatable capstan includes a first coupling feature and a drive system including a rotatable drive element. The rotatable drive element includes a second coupling feature. The first and second coupling features have an aligned engagement configuration in which rotation of the rotatable drive element induces rotation of the rotatable capstan and a non-aligned engagement configuration in which rotation of the rotatable drive element does not induce rotation of the rotatable capstan.

AUTOMATED ROTATION OF A NEEDLE IN A COMPUTER-ASSISTED SYSTEM
20230233202 · 2023-07-27 ·

Techniques for automated rotation of a needle in a computer-assisted system include an end effector having a drive mechanism configured to be coupled to a curved needle and configured to rotationally actuate the curved needle along an arcuate path and a control unit coupled to the drive mechanism. The control unit is configured to, in response to receiving a first input, cause the drive mechanism to rotationally actuate the curved needle by a first preset rotation amount along the arcuate path, and, in response to receiving a second input, cause the drive mechanism to rotationally actuate the curved needle by a second preset rotation amount along the arcuate path.
