ACTUATION CARRIAGE WITH INTEGRATED MEASUREMENT FOR ROBOTICALLY CONTROLLED SURGICAL INSTRUMENTS
A robotic system assembly comprises a robotic manipulator including an actuator assembly and a surgical instrument having a base body mountable to the actuator assembly. The base includes a first control input and a second control input, wherein the first and second control inputs are positioned on different sides of the base. The actuator assembly is moveable between open and closed positions to facilitate removal and replacement of surgical instruments. When in the closed positions, drive elements of the actuator assembly are positioned to drive the first and second control inputs of the surgical instrument to cause end effector movement or actuation.
1 . A robotic manipulator having an actuator assembly at its distal end, the actuator assembly having an open position in which a base of a surgical instrument may be introduced into the actuator assembly, and a closed position in which the base is releasably engaged.
2 . The manipulator of claim 1 where, the actuator assembly includes a first face having a first drive element and a second face having a second drive element, wherein the first and second faces are different faces.
3 . The manipulator of claim 2 , wherein the first and second faces are opposed faces.
4 . The manipulator of claim 1 , where the actuator assembly is expandable, either via pivoting, rotating, sliding or otherwise.
5 . The manipulator of claim 4 , where the expansion and contraction are controlled via either electrical or mechanical interaction between the instrument and the manipulator.
6 . The manipulator of claim 1 where the robotic manipulator includes a pass-through for instrument or camera cables.
7 . The manipulator of claim 6 , wherein the pass-through includes a portion of the actuator assembly.
8 . The manipulator of claim 1 , wherein the drive element are translatable relative to the manipulator to advance drive inputs on the base.
9 . A robotic system assembly comprising:
a robotic manipulator including an actuator assembly;
a surgical instrument having a body mountable to the actuator assembly, the body including a first control input and a second control input, wherein the first and second control inputs are positioned on different sides of the body or extend from the body in different directions.
10 . The system of claim 9 wherein the first and second control inputs extend from the body in opposite directions.
11 . The system of claim 9 wherein the first and second control inputs extend from the body in non-parallel directions.
12 . The system of claim 9 , wherein the first and second control inputs are operably associated with first and second drive elements of the actuator assembly when the surgical instrument is mounted to the robotic manipulator.
13 . The system of claim 12 , wherein a sterile barrier is disposed between the drive elements and the control inputs when the surgical instrument is mounted to the robotic manipulator.
14 . The robotic system assembly of claim 9 , wherein the actuator assembly is moveable between an open position in which the actuator assembly is configured to receive the body to a closed position in which the first and second control inputs are operably associated with first and second drive elements of the actuator assembly.
