Title:
BENDING MECHANISM AND MEDICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/105616
Kind Code:
A1
Abstract:
This bending mechanism comprises: a shaft part; a bendable part that has a proximal end connected to a distal end of the shaft part and can be bent in a direction orthogonal to an axial line of the shaft part; a tip portion having a proximal end connected to the bendable part; a manipulation rod or manipulation wire that is inserted through a groove or a hole provided along an axial direction of the shaft part and the bendable part, and has a distal end fixed to the bendable part; and a pressing part configured to be able to press the manipulation rod or the manipulation wire against a fixed portion of the shaft part. The bendable part is configured to be bendable by operating the manipulation rod or the manipulation wire in an extension direction of the manipulation rod or the manipulation wire. The pressing part presses the manipulation rod or the manipulation wire against the fixed portion of the shaft part, thereby generating a frictional force, and the manipulation rod or the manipulation wire is fixed to the pressing position by the frictional force in an axial direction.
