Abstract

Claims (27)

1 . A system for robotic-assisted surgery, comprising:

a base, including a computer;

a display electronically coupled to the computer;

a robot arm electronically coupled to the computer and movable based on commands processed by the computer; and

an end-effector, coupled to the robot arm, comprising a linear slide guide and a movable carriage adapted to fixedly secure a surgical instrument and slidably coupled to the linear slide guide;

wherein the end-effector is configured to allow linear sliding of the surgical instrument while limiting lateral movement,

wherein the end-effector includes tracking markers and the surgical instrument includes tracking markers,

wherein the movable carriage and the surgical instrument are configured for linear sliding along the linear slide guide of the end-effector.

2 . The system of claim 1 , wherein the linear slide guide includes a telescoping slide.

3 . The system of claim 2 , wherein the telescoping slide permits movement along a vertical axis.

4 . A system for robotic-assisted surgery, comprising:

a base, including a computer;

a display electronically coupled to the computer;

a robot arm electronically coupled to the computer and movable based on commands processed by the computer;

an end-effector, coupled to the robot arm, comprising a clamp configured to couple to the robot arm, a stationary linear guide rail, a moveable carriage slidably coupled to and linearly translatable along the guide rail, and an instrument mount attached to the moveable carriage and configured for securing a surgical instrument to the moveable carriage, wherein the movable carriage and guide rail allow for linear movement of the surgical instrument relative to the guide rail, and

wherein the active end-effector includes tracking markers and the surgical instrument includes tracking markers,

wherein the movable carriage and the surgical instrument are configured for linear sliding along the linear guide rail of the end-effector.

5 . The system of claim 4 , wherein the movable carriage and guide rail permit movement along a vertical axis.

6 . The system of claim 4 , wherein the carriage moves via a linear actuator.

7 . The system of claim 4 , wherein the active end-effector includes a brake configured to restrict movement of the moveable carriage.

8 . The system of claim 7 , wherein the brake acts as a depth stop for the surgical instrument.

9 . The system of claim 7 , wherein the instrument mount includes one or more sensors configured to correspond with one or more markers on the surgical instrument, wherein the one or more sensors (1) checks to see if the surgical instrument is properly attached to the instrument mount; (2) checks to verify the surgical instrument; and (3) allows for release of the brake to allow movement of the carriage.

10 . The system of claim 4 , wherein the instrument mount and the surgical instrument include a security feature.

11 . The system of claim 10 , wherein the security feature is an RFID tag that encodes information about the type of surgical instrument.

12 . The system of claim 10 , wherein the security feature is a pair of electrodes with a specific frequency and current.

13 . The system of claim 1 , wherein an instrument mount is attached to the movable carriage.

14 . The system of claim 4 , wherein the instrument mount is fixedly attached to the movable carriage.
