Abstract

An instrument manipulator and a robotic surgical system including an instrument manipulator are provided. In one embodiment, an instrument manipulator includes a plurality of independent actuator drive modules, each of the plurality of actuator drive modules including an actuator output, wherein each of the actuator outputs are configured to independently actuate a corresponding actuator input of a surgical instrument without force input from another actuator output. The instrument manipulator further includes a frame housing the plurality of independent actuator drive modules, the frame including a distal end from which each of the actuator outputs distally protrude for engaging the corresponding actuator inputs of the surgical instrument.

First claim

We claim:

1. A surgical instrument manipulator comprising:
a frame;
a first actuator drive module comprising a first motor and a first actuator output, the first actuator drive module being coupled to the frame via a first spring coupling; and
a second actuator drive module comprising a second motor and a second actuator output, the second actuator drive module being coupled to the frame via a second spring coupling;
wherein the first spring coupling independently couples the first actuator output to mechanically drive a first mechanical input of a surgical instrument coupled to the surgical instrument manipulator without the first mechanical input receiving any mechanical actuation from the second actuator output; and
wherein the second spring coupling independently couples the second actuator output to mechanically drive a second mechanical input of the surgical instrument coupled to the surgical instrument manipulator without the second mechanical input receiving any mechanical actuation from the first actuator output.

2. The manipulator of claim 1 , wherein the first actuator output drives the first mechanical input by rotational motion.

3. The manipulator of claim 1 , wherein the first actuator output drives the first mechanical input by lever motion.

4. The manipulator of claim 1 , wherein the first actuator output drives the first mechanical input by gimbal motion.

5. The manipulator of claim 1 , wherein the first actuator output drives the first mechanical input by rotational motion and the second actuator output drives the second mechanical input by lever motion.

6. The manipulator of claim 1 , wherein the first actuator output drives the first mechanical input by rotational motion and the second actuator output drives the second mechanical input by gimbal motion.

7. The manipulator of claim 1 , wherein the first actuator output drives the first mechanical input by lever motion and the second actuator output drives the second mechanical input by gimbal motion.

8. The manipulator of claim 1 further comprising:
a third actuator drive module comprising a third motor and a third actuator output, the third actuator drive module being coupled to the frame via a third spring coupling;
wherein the first spring coupling independently couples the first actuator output to mechanically drive the first mechanical input without the first mechanical input receiving any mechanical actuation from the third actuator output; and
wherein the second spring coupling independently couples the second actuator output to mechanically drive the second mechanical input without the second mechanical input receiving any mechanical actuation from the third actuator output;
wherein the third spring coupling independently couples the third actuator output to mechanically drive a third mechanical input of the surgical instrument coupled to the surgical instrument manipulator without the third mechanical input receiving any mechanical actuations from the first and second actuator outputs; and
wherein the first actuator output drives the first mechanical input by rotational motion, the second actuator output drives the second mechanical input by lever motion, and the third actuator output drives the third mechanical input by gimbal motion.
