Special tool for orthopaedic medical internal and external fixation instruments

Abstract

The invention discloses a special tool for orthopaedic medical internal and external fixation instruments. The special tool comprises a base, a fixed sleeve, an L-shaped clamping claw and a clamping block, wherein one end of the fixed sleeve is fixedly arranged on the base, and the other end of the fixed sleeve is hinged to one end of the symmetrical L-shaped clamping claw; the other end of the L-shaped clamping claw is rotatably connected with the clamping block through a pin roll; the upper end of the clamping block is hinged to the outer side end of the L-shaped clamping claw through a first electric telescopic pole; one side, away from the first electric pole, of the clamping block is symmetrically provided with movable plates; certain ends of the two movable plates are hinged to the clamping block; the other ends of the two movable plates are connected with a rubber cushion; a resisting plate is arranged between the two movable plates; and the resisting plate is connected with a resisting plate through a second electric telescopic pole at the inner side of the clamping block. The special tool adopts a novel design, and can drive the clamping block to perform angle regulation through the first electric telescopic pole, so that angle regulation is improved when a medical worker performs operation, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a special tool for orthopedic medical internal and external fixation devices. Background technique [0002] The department is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal shape and function of this system. When drilling bone holes, when using a drill jig to fix the electric drill, it is very troublesome to install and disassemble due to design reasons, and it is easy to loosen during use. It reduces the operational difficulty of medical personnel. [0003] The existing Chinese patent CN 108078608 A discloses a special tool for orthopedic medical internal and external fixation devices, including a mounting plate, the mounting plate is arranged in two Z-shaped symmetrical structures, and the bottom ...
