Methods for hybrid robotic laparoscopic surgery
View Patent ↗Methods and devices are provided for performing robotic surgery. In general, a surgical system is provided including an electromechanical tool with a first mode of operation in which the electromechanical tool mimics movement of a controller, and a second mode of operation in which the tool mirrors movement of the controller. A hybrid surgical device is also provided including an adapter matable to a handle assembly such that the adapter is electronically coupled to a motor of the handle assembly and is configured to communicate with the motor. A robotic laparoscopic surgical device is also provided including a motion sensor configured to sense movement of an electromechanical tool and an electromechanical arm that assists movement of the tool. A robotic surgical device is also provided including an electromechanical driver associated with a trocar and being configured to rotate and to translate a tool disposed through a passageway.
1. A surgical method, comprising:
manually manipulating a handle assembly on a surgical tool to manually cause movement of an end effector disposed within a body cavity, wherein a sensor ring surrounding an elongate shaft of the surgical tool senses the movement of the end effector caused by the manual manipulation of the handle assembly and an electromechanical arm coupled to the surgical tool provides power motion assistance to the manual manipulation of the handle assembly based on the sensed movement.
2. The method of claim 1 , wherein the power motion assistance is proportional to the sensed movement of the end effector.
3. The method of claim 1 , wherein the electromechanical arm is configured to selectively prevent movement of the surgical tool.
4. The method of claim 1 , further comprising selectively disabling the power motion assistance.
5. The method of claim 1 , wherein manipulating the handle assembly comprises moving the handle assembly in a first direction to cause the end effector to move in a second direction that is opposite to the first direction.
6. The method of claim 1 , wherein the power motion assistance comprises amplifying a force of the manual manipulation of the handle assembly.
7. A surgical method, comprising:
manipulating a handle assembly on a surgical tool to cause movement of an end effector disposed within a body cavity, wherein a sensor member through which the surgical tool is passed senses the movement of the end effector, and an electromechanical arm coupled to the surgical tool augments the movement of the end effector in at least one degree of freedom while limiting movement of the end effector in at least one other degree of freedom based on the sensed movement.
8. The method of claim 7 , wherein the augmented movement is proportional to the sensed movement of the end effector.
9. The method of claim 7 , further comprising selectively disabling the augmented movement.
10. The method of claim 7 , wherein manipulating the handle assembly comprises moving the handle assembly in a first direction to cause the end effector to move in a second direction that is opposite to the first direction.
11. A surgical method, comprising:
grasping a handle on a surgical tool to manually cause movement of an end effector on a distal end of the surgical tool disposed within a body cavity, wherein an external sensor through which the surgical tool is passed senses the manually-caused movement of the end effector, and a system coupled to the sensor causes an electromechanical arm coupled to the surgical tool to provide power motion assistance to the surgical tool when the sensor detects the manually-caused movement of the end effector.
12. The method of claim 11 , wherein the power motion assistance is proportional to the sensed manually-caused movement of the end effector.
13. The method of claim 11 , wherein the electromechanical arm is configured to selectively prevent movement of the surgical tool.
14. The method of claim 11 , further comprising selectively disabling the power motion assistance.
15. The method of claim 11 , wherein manually causing movement of the end effector includes manipulating the handle on the surgical tool to move the handle in a first direction to cause the end effector to move in a second direction that is opposite to the first direction.
