Problems solved by technology

[0005] However, even in the case of applying the technology disclosed in Japanese Patent Application Laid-Open No. 6-300975, when tension is applied to the shape memory alloy wire, the tubular member composed of a superelastic tube compressively deforms (snags), and the superelastic tube The radial deformation of the elastic tube hinders the transmission of tension (the transmission efficiency of power transmission decreases)

Embodiment Construction

[0026] Next, a driving force transmission mechanism and a robot system including the driving force transmission mechanism according to an embodiment of the present invention will be described. In addition, in this one embodiment, for example, a treatment manipulator system used in endoscopic surgery is assumed as the manipulator system.

[0027] figure 1 It is a figure which shows a structural example of the manipulator system to which the driving force transmission mechanism of this one embodiment was applied. Such as figure 1 As shown, the manipulator system includes: an operation input device 65 forming an operation unit; a motor control unit 66 forming a control unit; and a manipulator 67 .

[0028] The operation input device 65 reads information associated with the position, posture, and grip of the operator's hand 68 and outputs the information to the motor control unit 66 .

[0029] The motor control unit 66 controls the manipulator 67 according to the information as...

Abstract

A driving force transmitting mechanism (1) for transmitting driving force from a driving source is configured so as to comprise linear or rod-like flexible operation wires (95, 96), an inner pipe (2) which is a flexible guide member and through which the operation wires (95, 96) are inserted, and an outer pipe (3) which is provided on the outside radially of the inner pipe (2) and minimizes the deformation of the inner pipe (2).

Description

technical field [0001] The present invention relates to a driving force transmission mechanism for transmitting a driving force from a driving source and a robot system including the driving force transmission mechanism. Background technique [0002] As the technology related to the driving force transmission mechanism and the robot system, for example, the following technology is disclosed in Japanese Patent Application Laid-Open No. 6-81503. That is, in Japanese Patent Application Laid-Open No. 6-81503, a bending device for an endoscope is disclosed as a driving force transmission mechanism. The bending device for an endoscope includes: a bending operation wire for imparting flexibility. A flexible transmission member in which the bending portion connected to the front end side of the tube is bent; and a flexible guide tube composed of a densely wound coil that guides the bending operation wire. [0003] When the technique disclosed in Japanese Patent Application Laid-Ope...
