Abstract

The invention relates to the field of orthopedic surgical instruments, and provides a guiding device for orthopedic surgery, which includes a fixed base, a support shaft is arranged inside the fixed base, and a first rotating plate and a second rotating plate are sleeved on the supporting shaft , the first rotating plate is provided with a rotating cavity, and one side of the first rotating plate is provided with a rotating outlet communicating with the rotating cavity, and the top surface of the first rotating plate is provided with a connecting through hole that runs through the rotating cavity and cooperates with the support shaft, The second rotating plate includes a rotating part located in the rotating cavity and sleeved on the support shaft. The side of the rotating part is extended with a connecting part passing through the rotating outlet; the connecting part and the end of the first rotating plate away from the supporting shaft are provided with through Fix the clamping arm of the base, and the two clamping arms are set in mirror image; one end of the clamping arm is provided with a guide assembly, and the other end of the two clamping arms is provided with a control assembly, and the control part of the control assembly is connected to the The clamping arm is hinged; it solves the problem that the structure of the existing drilling guiding device is complex and the guiding accuracy becomes smaller after long-term use.

Description

technical field [0001] The invention relates to the field of orthopedic surgical instruments, in particular to a guiding device for orthopedic surgery. Background technique [0002] When performing fracture surgery, according to the fracture location and injury status of the patient, it is necessary to reset and maintain the fractured bone and fix it with drilling nails. When drilling nails, most of them use direct drilling and placement of screws and surrounding soft tissues without guidance and based on the experience of the surgeon. The coverage is difficult to observe, and it is impossible to enter in the ideal channel, which will easily lead to the unsatisfactory channel of the drill nail and the offset of the hole. After X-ray observation, the position is often not ideal, and it is necessary to pull out the nail again and drill the hole again. Nails, which increase the surgical trauma and prolong the operation time. [0003] In the prior art, there is a drilling guide...
