Abstract

The invention discloses an intraoperative percutaneous fracture end temporary fixation and reduction device. The device comprises a first vertical fixing rod and a second vertical fixing rod which arefixed onto two broken bones separately, the first vertical fixing rod is provided with a first transverse rod, the second vertical fixing rod is provided with a second transverse rod, an arc disc isarranged between the first vertical fixing rod and the second vertical fixing rod and concentrically provided with a first arc guide groove and a second arc guide groove, the first transverse rod is slidingly inserted in the first arc guide groove, the second transverse rod is slidingly inserted in the second arc guide groove, and the arc disc is provided with angle scale marks matched with the first arc guide groove and the second arc guide groove. The invention further discloses an operation method of the intraoperative percutaneous fracture end temporary fixation and reduction device. Compared with the prior art, the intraoperative percutaneous fracture end temporary fixation and reduction device is reasonable in structure and high in positioning precision, the fracture end can be effectively fixed, the risk of re-displacement of the fracture end is reduced, the iatrogenic injury of repeated reduction in a simulated operation is reduced, the operation time is saved, the bleeding amount is reduced, and the pain of patients is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an auxiliary device for bone fracture surgery, in particular to a device for temporary fixation and reset of percutaneous fracture ends during operation and an operating method thereof. Background technique [0002] Orthopedics is a discipline that combines clinical technology and material science. Its development is not only related to the professional skill level of surgeons, but also closely related to the development of surgical instruments and materials. For obviously displaced or comminuted fractures, surgical open fracture reduction and internal fixation has been gradually accepted by surgeons and the outside world. In many cases, doctors will train practical skills through teaching simulated surgery. In teaching simulated surgery, fracture reduction is an important technical part of the operation. It is difficult to reduce the fracture under the pull of bilateral muscles in...
