Abstract
A surgical instrument for coupling to a robotic surgical assembly configured to transfer rotational forces to the surgical instrument is provided. The surgical instrument includes an elongated shaft, an end effector coupled to a distal end of the elongated shaft, and a drive assembly operatively coupled to the end effector. The drive assembly includes one or more cables connected to the end effector. Movement of the one or more cables actuates a movement of the end effector. The one or more cables may be coated with parylene.

A surgical instrument for coupling to a robotic surgical assembly configured to transfer rotational forces to the surgical instrument, the surgical instrument comprising:
- an elongated shaft;
- an end effector coupled to a distal end of the elongated shaft;
- a drive assembly operatively coupled to the end effector and including at least one cable connected to the end effector, wherein movement of the at least one cable actuates a movement of the end effector;
- and
- a housing supported on a proximal end of the elongated shaft, the housing configured to couple to the robotic surgical assembly, wherein the housing includes a side surface supporting a ramped camming surface, the ramped camming surface being configured to enable the housing to be transversely coupled to the robotic surgical assembly such that a corresponding camming surface of the robotic surgical assembly engages the ramped camming surface of the surgical instrument to cam the housing in a proximal direction in response to a transverse movement of the housing relative to the robotic surgical assembly.
A robotic surgical instrument comprising:
- a housing configured to couple to a robotic surgical assembly;
- an elongated shaft extending distally from the housing;
- an end effector extending distally from the elongated shaft;
- and
- a drive assembly supported in the housing, the drive assembly including a cable connected to the end effector, wherein the cable is movable to actuate the end effector, wherein the housing includes a side surface supporting a ramped camming surface, the ramped camming surface being configured to enable the housing to be transversely coupled to the robotic surgical assembly such that a corresponding camming surface of the robotic surgical assembly engages the ramped camming surface of the surgical instrument to cam the housing in a proximal direction in response to a transverse movement of the housing relative to the robotic surgical assembly.
