Abstract
An end effector assembly of a robotic surgical instrument includes a clevis, first and second jaw members supported by the clevis, and a cam bar configured to move the first and second jaw members between an open state and a closed state.
Claims18
An end effector assembly of a robotic surgical instrument, the end effector assembly comprising:
- a clevis;
- a first jaw member pivotably coupled to the clevis via a pivot pin, the first jaw member defining a cam slot;
- a second jaw member coupled to the clevis;
- and
- a cam bar having a distal end portion received within the clevis, the distal end portion of the cam bar having a cam pin received in the cam slot defined in the first jaw member, the distal end portion of the cam bar defining a cutout therein, wherein the cam bar is configured to move through the clevis, whereby the cam pin of the cam bar pivots at least one of the first or second jaw members relative to the clevis between a closed state in which the first and second jaw members are closer to one another, and an open state in which the first and second jaw members are further apart from one another.

A robotic surgical instrument, comprising:
- a housing configured to be operably coupled to a surgical robotic arm;
- a shaft assembly extending distally from the housing;
- and
- an end effector assembly including:
- a clevis coupled to a distal end portion of the shaft assembly and configured to articulate relative thereto;
- a first jaw member pivotably coupled to the clevis via a pivot pin, the first jaw member defining a cam slot;
- a second jaw member coupled to the clevis;
- and
- a cam bar having a distal end portion received within the clevis, the distal end portion of the cam bar having a cam pin received in the cam slot defined in the first jaw member, the distal end portion of the cam bar defining a cutout therein, wherein the cam bar is configured to move through the clevis, whereby the cam pin of the cam bar pivots at least one of the first or second jaw members relative to the clevis between a closed state in which the first and second jaw members are closer to one another, and an open state in which the first and second jaw members are further apart from one another.
