Abstract
A passive end effector of a surgical system includes a base, a first mechanism, and a second mechanism. The base attaches to an end effector coupler of a robot arm positioned by a surgical robot. The first mechanism extends between a rotatable connection to the base and a rotatable connection to a tool attachment mechanism. The second mechanism extends between a rotatable connection to the base and a rotatable connection to the tool attachment mechanism. The first and second mechanisms pivot about the rotatable connections to constrain movement of the tool attachment mechanism to a range of movement within a working plane. The tool attachment mechanism is configured to connect to a surgical saw including a saw blade for cutting.
Claims9
A surgical system comprising:
- a passive end effector including,
- a base configured to attach to an end effector coupler of a robot arm positioned by a surgical robot,
- a first mechanism extending along a first plane, the first mechanism extends between a rotatable connection to the base and a rotatable connection to a second mechanism, and
- a second mechanism extending along a second plane, the second mechanism extends between a rotatable connection to the first mechanism and a rotatable connection to a tool attachment mechanism,
- wherein the first and second mechanisms pivot about the rotatable connections to constrain movement of the tool attachment mechanism to a range of movement within a working plane, the tool attachment mechanism being configured to connect to a surgical saw having a saw blade configured to oscillate for cutting, the saw blade extending along the working plane, and
- wherein the first plane is positioned vertically above the second plane and the second plane is positioned vertically above the working plane.
