Surgical teleoperated device for remote manipulation
A mechanical teleoperated device for remote manipulation includes a slave unit having a number of slave links interconnected by a plurality of slave joints; an end-effector connected to the slave unit; a master unit having a corresponding number of master links interconnected by a plurality of master joints; and a handle connected to a distal end of the master unit. The device further includes first device arranged to kinematically connect the slave unit with the master unit, second device arranged to kinematically connect the end-effector with the handle, and a mechanical constraint device configured to ensure that one master link of the master unit is guided along its longitudinal axis so that the corresponding slave link of the slave unit always translates along a virtual axis parallel to the longitudinal axis of the guided master link in the vicinity of the remote manipulation when the mechanical teleoperated device is operated.
1. A method for performing surgery using a teleoperated surgical system, the method comprising:
manipulating a first handle coupled to a first master unit, the first master unit operatively coupled to a first slave unit, to move at least one of a first plurality of master links of the first master unit to thereby move at least one of a first plurality of slave links of the first slave unit to thereby move a first end-effector coupled to the first slave unit to perform a surgical procedure;
manipulating a second handle coupled to a second master unit, the second master unit operatively coupled to a second slave unit, to move at least one of a second plurality of master links of the second master unit to thereby move at least one of a second plurality of slave links of the second slave unit to thereby move a second end-effector coupled to the second slave unit to perform the surgical procedure; and
moving the first and second master units vertically relative to a base structure coupled to the first and second master units via a telescoping station mounted within the base structure to position the first and second master units in a desired position relative to a surgeon performing the surgical procedure.
2. The method of claim 1 , further comprising moving a base structure coupled to the first and second master units to position the first and second master units in a desired position relative to a patient undergoing the surgical procedure.
3. The method of claim 2 , wherein moving the base structure comprises wheeling the base structure to the desired position using wheels coupled to the base structure.
4. The method of claim 3 , further comprising locking the base structure in a stationary configuration.
5. The method of claim 1 , further comprising moving a base structure coupled to the first and second slave units to position the first and second slave units in a desired position relative to a patient undergoing the surgical procedure.
6. The method of claim 5 , wherein moving the base structure comprises wheeling the base structure to the desired position using wheels coupled to the base structure.
7. The method of claim 6 , further comprising locking the base structure in a stationary configuration.
8. The method of claim 5 , further comprising rotating at least one of the first or second slave units relative to the base structure.
9. The method of claim 1 , further comprising monitoring a vicinity of remote telemanipulation via a display.
10. The method of claim 9 , wherein the display is mounted on a base structure coupled to the first and second master units.
11. The method of claim 1 , further comprising measuring movement of at least one of the first plurality of master links to permit corresponding movement of at least one of the first plurality of slave links.
12. The method of claim 1 , further comprising measuring force exerted on at least one of the first plurality of master links.
13. The method of claim 1 , wherein the first and second end-effectors are each movable in at least three degrees-of-freedom.
14. The method of claim 1 , wherein manipulating the first handle causes movement at the first end-effector using mechanical technology.
15. The method of claim 1 , wherein manipulating the first handle to move the first end-effector and manipulating the second handle to move the second end-effector is done without electronics, actuators, or software, or combinations thereof.
16. The method of claim 1 , wherein manipulating the first handle comprises moving a plurality of handle links of the first handle.
17. The method of claim 16 , wherein moving the plurality of handle links comprises moving the plurality of handle links with tips of a thumb and index finger of a surgeon performing the surgical procedure.
18. The method of claim 1 , wherein the first end-effector is a surgical tool that is interchangeable.
19. The method of claim 18 , wherein the surgical tool is selected from scissors, scalpels, cutters, or needle holders.
