Tibia intercondyloid spine fracture reduction fixing device

Abstract

The invention provides a tibia intercondyloid spine fracture reduction fixing device which comprises reduction fixing pincers, a plurality of bone tunnel machining limiting plates and a fracture sheet pressing plate. The reduction fixing pincers are provided with a limiting frame used for being matched with the limiting plates. The fracture sheet pressing plate is provided with a guiding hole used for guiding a kirschner wire. A fracture sheet is provided with a limiting hole matched with the reduction fixing pincers. Compared with the similar design, the small and practical restoring and fixing pincers effectively improve the anatomical reduction efficiency and accuracy of the intercondyloid spine fracture sheet, the fracture sheet is pressed when bone tunnels are machined, and secondary dislocation is avoided when the bone tunnels are machined; moreover, the reduction fixing pincers provide inlets of the multiple bone tunnels and angle locating devices for surgeons to select, the generality of the reduction fixing pincers is improved, and the reduction fixing pincers can deal with tibia anatomic variation of multiple situations.

Description

technical field [0001] The invention relates to an orthopedic surgical instrument, in particular to a reduction and fixation device for tibial intercondylar spine fracture. Background technique [0002] The traditional surgical method for the treatment of intercondylar spine fractures is to press the bone fragments avulsed due to intercondylar spine fractures back to their anatomical position as far as possible under knee arthroscopy, and drill three bone tunnels obliquely upward under the tibial plateau, among which The bone tunnel in the middle is inserted into the Kirschner wire to fix the reduced bone fragment, and then the fixation wire is passed through the bone tunnel on one side, across the intercondylar spinous fragment from above the Kirschner wire, and then through the bone tunnel on the other side. Pull out the fixed steel wire, and finally fix the avulsed bone block firmly in the anatomical position with the help of the Kirschner wire, and finally tie the two st...

Problems solved by technology

However, most of the above-mentioned processes are carried out without special auxiliary tools for the treatment of intercondylar spine fractures. It is difficult to restore the avulsed bone fragments to the anatomical position during the arthroscopic reduction process. Due to the poor positioning accuracy of the bone tunnel, the bone fragments that have been reset will be dislocated again, which not only increases the difficulty of the operation, but also easily causes side injuries

Not only is it not conducive to the operator's operation during the operation, but it is also not conducive to the postoperative recovery and long-term efficacy of the patient
