Abstract

The invention provides a fixture. The fixture comprises a clamping mechanism, a force applying sleeve and a columnar body assembling the clamping mechanism and the force applying sleeve; the clampingmechanism is provided with two mutually hinged clamping bodies, and at least one clamping body is provided with a rolling part; the columnar body is provided with a first through hole running throughthe side wall of the columnar body in the axial direction, the clamping mechanism is contained in the first through hole, and the clamping mechanism is assembled on the columnar body through a rotating shaft at the hinged portion; a second through hole is formed in the columnar body in the axial direction, and the second through hole is communicated with the first through hole; an arc-shaped surface cooperating with the rolling part is arranged on the inner wall of the force applying sleeve which sleeves the columnar body, when the force applying sleeve moves along the columnar body, the forceapplying sleeve compresses the rolling part, the rolling part is in a compressing or releasing state in the force applying sleeve, and then mechanical opening or closing of the clamping bodies is achieved. Operation is easy, and high clamping stability is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a clamp. Background technique [0002] In the production process of medical devices, fixtures are often used, for example, balloon catheters and drug stent delivery systems are widely used in the process of cardiovascular intervention. The distal rod part of the tube is clamped to facilitate the coating of the surface with a hydrophilic coating, thereby reducing the surface friction of the balloon catheter / drug stent delivery system. At present, the traditional fixture is composed of a clamping component and a spring component, and the clamping process of the object is realized through the elasticity of the spring itself and the rotation or movement of the clamping component. However, after repeated use, the self-elasticity of the spring assembly in the clamping structure will weaken, that is, the elastic fatigue defect of the spring, which will eventually affect the...
