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 m

Embodiment Construction

[0017] Combine below figure 1 The present invention is further described.

[0018] An internal fixation guide for fracture pressurization reduction, including a positioning frame 10, a movable baffle 20 and a guide part 30, the positioning frame 10 is a C-shaped structure, and the movable baffle 20 is hinged at one end of the positioning frame 10, after the calcaneus fracture is reset , the movable baffle 20 can be placed in the position of the load distance, because the movable baffle 20 can rotate around the hinge point, so it can use the load distance protrusion position with different angle positions, and can be used for reduction and fixation of limb fractures. The guide part 30 is mounted on the other end of the positioning frame 10 through threads, and the screw-in direction of the guide part 30 points to the end of the positioning frame 10 where the movable baffle 20 is located. The spacer 10 is formed with several limit holes 12 that can be inserted into the Kirschne...

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...
