Abstract
A coupler can connect one or more instruments to a robotic surgical arm. The coupler can include a base and an actuator. The base can be securable to the robotic surgical arm. The actuator can be operable to release or secure the stem to the base and the robotic surgical arm.
Claims16
A coupler for connecting one or more instruments to a robotic surgical arm, the coupler comprising:
- a base securable to the robotic surgical arm, the base comprising:
- a collar at least partially defining a stem bore extending at least partially into the base, the stem bore configured to receive a tool stem therein, the stem bore defining an axis, the collar including a fixed portion and a movable portion cantilevered from the fixed portion;
- a retainer engageable with the tool stem to limit axial movement of the tool stem with respect to the collar;
- and
- an actuator connected to the collar and operable to move the collar between an open position and a closed position, the collar engageable with the tool stem in the closed position to secure the tool stem to the base and the robotic surgical arm, and the actuator operable to move the movable portion with respect to the fixed portion.

A robotic surgical arm assembly including a robotic surgical arm, the robotic surgical arm assembly comprising:
- a tool stem;
- and
- a coupler securable to the robotic surgical arm, the coupler comprising:
- a collar at least partially defining a stem bore configured to receive the tool stem therein, the stem bore defining an axis, the collar including a fixed portion and a movable portion cantilevered from the fixed portion;
- a retainer engageable with the tool stem to limit axial movement of the tool stem with respect to the collar;
- and
- an actuator connected to the collar and operable to move the collar between an open position and a closed position, the collar engaged with the tool stem in the closed position to secure the tool stem to the coupler and the robotic surgical arm, and the actuator operable to move the movable portion with respect to the fixed portion.
