Abstract

An operation support device includes an operation part in which the operation input is performed by an operator, an action part to which a surgical tool is attached and which is driven by the operation input, a drive source that is provided in the operation part, and generates a driving force which adjusts the manipulation resistance at the time of the operation input, and a control unit that sets the magnitude and direction of the driving force, wherein the control unit sets the magnitude and direction of the driving force based on the operation input to the operation part.

Claims

1. An operation support device which includes an operation part that performs an operation input by a manipulator, and an action part to which a surgical tool is attached and which is driven by the operation input, the operation support device comprising:

a drive source which is provided in the operation part and generates a driving force which adjusts a manipulation resistance at the time of the operation input; and

a control unit which sets a magnitude and a direction of the driving force,

wherein the control unit sets the magnitude and the direction of the driving force based on the operation input to the operation part.

2. The operation support device according to claim 1, wherein

the operation part comprises a switch,

the control unit sets the driving force based on one of a plurality of modes, and

when the switch is operated by the operator, the mode used when the control unit sets the driving force is switched.

3. The operation support device according to claim 2, wherein

the switch is configured to be operated by a hand or a foot of the operator.

4. The operation support device according to claim 2, wherein

the surgical tool is in an active state when performing an operation, and

the switch combines function to switch the surgical tool to the active state.

5. The operation support device according to claim 1, further comprising:

a detection part that detects an amount of motion of the operation part using the operation input,

wherein the control unit sets the driving force so that the driving force is increased as the amount of motion is reduced.

6. The operation support device according to claim 5, wherein

the control unit sets the driving force so as to relatively increase when the amount of motion is equal to or less than a predetermined threshold value.

7. The operation support device according to claim 1, further comprising:

a detection part that detects an amount of motion of the operation part using the operation input,

wherein the control unit sets the driving force so that the driving force is increased as the amount of motion is increased, and a relationship between an amount of change of the amount of motion and an amount of change of the driving force is changed depending on a value of the amount of motion.

8. The operation support device according to claim 7,

wherein the control unit sets the driving force so as to be relatively increase when the amount of motion is equal to or greater than a predetermined threshold value.

9. The operation support device according to claim 1, wherein

the surgical tool is provided in a plural number in the action part in an attachable and detachable manner, and the respective surgical tools have identification information, and

the control unit sets the magnitude and the direction of the driving force based on the identification information of the surgical tool mounted on the action part.
