Robot arm and methods of use
A robot arm and method for using the robot arm. Embodiments may be directed to an apparatus comprising: a robot arm; an end effector coupled at a distal end of the robot arm and configured to hold a surgical tool; a plurality of motors operable to move the robot arm; and an activation assembly operable to send a move signal allowing an operator to move the robot arm.
1. A robotic surgical system, comprising:
a robot arm;
a passive axis arm having a base and a shaft extending from the base, the base configured to be coupled to a distal end of the robot arm;
an end effector coupled to a first end of the shaft and configured to hold a surgical tool having optical markers;
a plurality of motors operable to move the robot arm; and
an activation assembly operable to send a move signal allowing an operator to move the robot arm,
wherein the base of the passive axis arm is coupled to a second end of the shaft, wherein the shaft is rotatable when a locking mechanism is in a first position and not moveable when the locking mechanism is in a second position,
wherein the activation assembly is in the form of a bracelet on the end effector.
2. The system of claim 1 , wherein the locking mechanism is a rotatable knob theadedly fixed to the base.
3. The system of claim 2 , wherein the rotatable knob is a threaded screw.
4. The system of claim 2 , wherein the locking mechanism is translatable in an axis perpendicular to a longitudinal axis of the base.
5. The system of claim 2 , wherein the shaft is rotatable in the same axis as the base of the passive axis arm.
6. The system of claim 1 , wherein the end effector is guide tube.
7. The system of claim 1 , wherein the end effector includes a plurality of optical markers.
8. The system of claim 1 , wherein the passive axis arm is manually moved to a first desired trajectory.
9. The system of claim 8 , wherein the robotic surgical system moves the end effector to a second position on the desired trajectory.
10. A robotic surgical system, comprising:
a robot arm;
a passive axis arm having a base and a shaft extending from the base, the base configured to be coupled to a distal end of the robot arm;
an end effector coupled to a first end of the shaft and configured to hold a surgical tool having optical markers;
a plurality of motors operable to move the robot arm; and
an activation assembly operable to send a move signal allowing an operator to move the robot arm,
wherein the base of the passive axis arm is coupled to a second end of the shaft, wherein the shaft is rotatable with respect to the base of the passive axis arm
wherein the activation assembly is in the form of a bracelet on the end effector.
11. The surgical system of claim 10 , wherein the surgical system further includes a locking mechanism to lock the position of the shaft to the base.
12. The system of claim 11 , wherein the locking mechanism is a rotatable knob theadedly fixed to the base.
13. The system of claim 12 , wherein the rotatable knob is a threaded screw.
14. The system of claim 11 , wherein the locking mechanism is translatable in an axis perpendicular to a longitudinal axis of the base.
15. The system of claim 10 , wherein the shaft is rotatable in the same axis as the base of the passive axis arm.
16. The system of claim 10 , wherein the end effector is guide tube.
17. The system of claim 10 , wherein the end effector includes a plurality of optical markers.
18. The system of claim 10 , wherein the passive axis arm is manually moved to a first desired trajectory.
19. The system of claim 18 , wherein the robotic surgical system moves the end effector to a second position on the desired trajectory.
