Fracture compression restoration internal fixation guiding device

Abstract

The invention discloses a fracture compression restoration internal fixation guiding device, comprising a positioning frame, a movable baffle plate and a guide part, wherein the movable baffle plate is hinged on one end of the positioning frame, the guide part is installed on the other end of the positioning frame through threads, the screw-in direction of the guide part points to one end of the movable baffle plate on the positioning frame, and a plurality of limit holes for insertion of Kirschner pins are formed on the positioning frame. By designing a hinged movable baffle plate on the positioning frame, the positioning frame can be installed at a plurality of positions when in use, and both ends of the positioning frame can be guaranteed to have supporting points. It can be used not only for calcaneal fracture reduction and fixation, but also for limb fracture reduction and fixation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fracture pressure reduction internal fixation guide. Background technique [0002] Calcaneal fracture is a common tarsal fracture, its incidence accounts for 2% of systemic fractures, and accounts for 60%-65% of all tarsal fractures. Improper management of calcaneal fractures can cause foot pain and deformity, which can seriously affect limb function. Because the cortical bone of the calcaneus is relatively thin and the cancellous bone is relatively abundant, the vertical pressure of the talus often causes the calcaneus to collapse and compress when a fracture occurs, especially the posterior articular surface often presents a comminuted fracture. The most important factor affecting the prognosis of the affected foot in calcaneal fractures is the integrity and displacement of the posterior articular surface. Therefore, the reduction and stable fixation of the bone fra...

Problems solved by technology

[0003] In conventional surgery, the positioning of the calcarid screw is only determined by the experience of the surgeon, which is difficult to avoid the error of human factors, resulting in unsatisfactory positioning of the calcaneal screw, which affects the surgical effect, and in severe cases, the operation fails

The modified L-shaped incision on the lateral side of the calcaneus is the mainstream approach for calcaneus fracture surgery. This approach can provide sufficient exposure for the restoration of the posterior articular surface. However, it is still difficult to expose the talus process through this approach. It is still necessary to rely on the doctor's experience and technology when driving the screw from the screw hole of the outer wall plate to the load distance
