Hand controller for robotic surgery system
A Robotic control system has a wand, which emits multiple narrow beams of light, which fall on a light sensor array, or with a camera, a surface, defining the wand's changing position and attitude which a computer uses to direct relative motion of robotic tools or remote processes, such as those that are controlled by a mouse, but in three dimensions and motion compensation means and means for reducing latency.
1. A hand controller for a robotic surgery system, the hand controller comprising:
a body extending linearly between a proximal end and a distal end;
a first control pivotally attached to the body, the first control configured to permit a user to control a first function of a surgical instrument; and
a second control supported by a side of the body at a location between the proximal end and the distal end, the second control configured to linearly move in a direction parallel to a length of the body to permit a user to control a second function of the surgical instrument, the second function being different from the first function.
2. The hand controller of claim 1 , wherein the first control comprises at least one lever.
3. The hand controller of claim 2 , wherein the first function of the surgical instrument comprises adjusting a distance between first and second jaws of an end effector of the surgical instrument.
4. The hand controller of claim 3 , wherein the distance between the first and second jaws of the end effector of the surgical instrument is adjusted responsive to movement of the at least one lever.
5. The hand controller of claim 1 , wherein the first control comprises an opening configured to receive a finger therethrough.
6. The hand controller of claim 1 , wherein the second function of the surgical instrument comprises a linear movement of an end effector of the surgical instrument.
7. The hand controller of claim 6 , wherein:
a linear movement of the second control causes the linear movement of an end effector.
8. The hand controller of claim 1 , wherein the second control comprises a slidable control.
9. The hand controller of claim 1 , wherein operation of one or both of the first control and the second control causes a haptic feedback to be provided to the user.
10. The hand controller of claim 9 , wherein the first function of the surgical instrument comprises adjusting a distance between a first jaw and a second jaw of an end effector of the surgical instrument, and wherein the haptic feedback provided to the user comprises pinching feedback that simulates a force applied by the first jaw and the second jaw.
11. The hand controller of claim 1 , further comprising a spring configured to bias the first control.
12. The hand controller of claim 11 , wherein the spring is configured to bias the first control to a position in which the first function of the surgical instrument is not activated.
13. The hand controller of claim 12 , wherein the position comprises an open position.
14. A hand controller for a robotic surgery system, the hand controller comprising:
a body extending linearly between a proximal end and a distal end;
a first control pivotally coupled to the body, a finger ring attached to the first control and configured to receive a finger of a user's hand therethrough, the first control configured to cause activation of a first function of a surgical instrument; and
a second control supported by a side of the body at a location between the proximal end and the distal end, the second control configured to slide along the side of the body to cause activation of a second function of the surgical instrument, the second function being different from the first function.
15. The hand controller of claim 14 , wherein the first control comprises a lever pivotally attached to the body.
16. The hand controller of claim 14 , wherein the first function of the surgical instrument comprises adjusting a distance between first and second jaws of an end effector of the surgical instrument.
17. The hand controller of claim 16 , further comprising a second finger ring on an opposite side of the body from the first control, the second finger ring configured to receive another finger of the user's hand therethrough.
18. The hand controller of claim 14 , wherein operation of one or both of the first control and the second control causes a haptic feedback to be provided to the user.
19. The hand controller of claim 18 , wherein the first function of the surgical instrument comprises adjusting a distance between a first jaw and a second jaw of an end effector of the surgical instrument, and wherein the haptic feedback provided to the user comprises pinching feedback that simulates a force applied by the first jaw and the second jaw.
20. A hand controller for a robotic surgery system, the hand controller comprising:
a body extending linearly between a proximal end and a distal end;
a first control pivotally attached to the body, the first control configured to permit a user to control a first function of a surgical instrument; and
a second control supported by a side of the body at a location between the proximal end and the distal end, the second control configured to receive an input in a direction generally parallel to a length of the body to permit a user to control a second function of the surgical instrument, the second function being different from the first function.
