Fixing device for orthopedic surgery

Abstract

The invention discloses a fixing device for orthopedic surgery. The fixing device comprises a placement plate; installation blocks are fixedly installed on both sides of the front face of the placement plate, a semicircular clamp ring is arranged on the front face of each installation block, positioning pins are arranged on both sides of the front face of each clamp ring, and one end of each positioning pin penetrates through the corresponding clamp ring and extends into the corresponding installation block; a fixed plate is fixedly installed at the top of the placement plate, a motor is fixedly installed on the front face of the fixed plate, and a rotating disc is fixedly installed on an output shaft of the motor. According to the fixing device, by the arrangement of the installation blocks, the clamp rings and the positioning pins, the leg of a patient can be fixed; by the arrangement of the fixed plate, the motor, the rotating disc, a moving plate, a moving rod, a first clamping plate and a second clamping plate, the leg of the patient can be fixed, the accuracy of surgical drilling can be guranateed, the surgical efficiency can be improved, and meanwhile the problems that the fixing effect is poor, adjustment is inconvenient, the drilling precision is reduced, and consequently a lot of time is wasted are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixation device for orthopedic surgery. Background technique [0002] Orthopedic devices generally refer to professional medical devices specially used for orthopedic surgery. According to the classification of the State Food and Drug Administration, they are often divided into: Class I, Class II and Class III. According to the use and performance, they can be divided into: joint devices , spine instruments, trauma instruments, and basic instruments, etc. The existing orthopedic drills use motor-driven drills, which require manual control of the verticality when drilling, and are easy to shake when drilling. At present, for orthopedic patients During the treatment process, it is often necessary to fix the injured part of the patient with a bone plate. Some of them also need to drill holes in the bone and insert screws for bone treatment. The general method is to use a d...
