Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a lateral locking system for the proximal tibia. Background Art

[0002] Open tibial fractures are one of the common fracture types in clinical practice. When fixed with a steel plate, complications such as poor wound healing, bone exposure, and infection are likely to occur. Therefore, a lateral locking system is required for fixation. In the traditional tibial lateral locking system, only multiple vertical Kirschner wires are fixedly arranged at intervals on the locking frame. This form results in poor fixation stability of the tibial lateral locking system, prone to nonunion of bones. Moreover, the traditional tibial lateral locking system has a poor fit with the tibia, making it difficult to stably fix when a fracture occurs at the proximal tibia. Therefore, improvements are still needed. Summary of the Utility Model

[0003] The utility model provides a lateral locking system for the proximal tibia to solve the above-mentioned problems, including a locking frame, transverse Kirschner wires, and vertical Kirschner wires. The locking frame is set in a T-shaped structure. Multiple pin holes are provided on both the transverse leg and the longitudinal leg of the locking frame. The transverse leg of the locking frame is set in an arc structure. Multiple transverse Kirschner wires are provided and are inserted into the pin holes on the transverse leg and the longitudinal leg of the locking frame. One vertical Kirschner wire is provided and is obliquely upward inserted into the pin hole at the rightmost end of the transverse leg.

[0004] Preferably, the locking frame is fitted and installed on the tibia.

[0005] Preferably, the upper side of the transverse leg of the locking frame is provided with continuous corrugations, and the wave crests of the continuous corrugations correspond to the respective pin holes of the transverse leg.

[0006] Preferably, the vertical Kirschner wire is supported at the bottom of the transverse Kirschner wire.

[0007] Preferably, the length of the leftmost end of the transverse leg of the locking frame does not exceed the position of the tendon.

[0008] Preferably, the position of the rightmost pin hole on the transverse leg is lower than the positions of the other pin holes on the transverse leg.

[0009] Preferably, protrusions are provided on the outer periphery of the pin holes.

[0010] The beneficial effects of the utility model are as follows: The structure of the utility model is reasonably designed and convenient to use. By setting a T-shaped locking frame, it is convenient to fix the transverse and longitudinal Kirschner wires. The transverse leg of the locking frame is set in an arc structure, which can better fit the tibia. The vertical Kirschner wire pressing on the transverse Kirschner wire can make the locking frame fix and lock the tibia more firmly. Description of the Drawings
