Abstract

The invention relates to a tibia fracture reduction external fixing system with a looseness monitoring function, which comprises a fixing needle group and an external fixing frame, the fixing needle group comprises a main fixing needle and at least one side fixing needle, and the external fixing frame comprises a main fixing clamp, a main connecting rod, an adjustable fixing clamp, a side connecting rod and a connecting rod fastening nail. The outer end of each main fixing needle is provided with a main fixing clamp, and all the main fixing clamps are jointly fixed to the main connecting rod through connecting rod fastening nails. One side fixing needle is provided with an adjustable fixing clamp, one main fixing needle is provided with the other adjustable fixing clamp, and the two adjustable fixing clamps are jointly fixed to the side connecting rod through connecting rod fastening nails respectively; and a displacement monitoring alarm mechanism is arranged in the connecting rod fastening nail. According to the invention, higher precision of fracture reduction can be ensured, and the adjustment is also very convenient; when the outer fixing frame looses and accidentally moves, the displacement monitoring and alarming mechanism can sense and send out an alarming signal.

Description

technical field

[0001] The invention relates to an external fixation system for tibial fracture reduction with a loosening monitoring function, belonging to the technical field of medical devices. Background technique

[0002] Located on the inner side of the lower leg, the tibia is one of two long bones in the lower leg and plays an important role in supporting the body's weight. The upper end of the tibia is enlarged to form the knee joint with the lower end of the femur and the patella.

[0003] At present, there are many treatment methods for tibial fractures, but each has its own shortcomings in clinical application: 1. Manual reduction plaster or small splint external fixation is only suitable for some stable fractures such as transverse or short oblique without displacement. Stable fractures are less practical. 2. Integrative Chinese and Western medicine therapy such as calcaneal traction and small splint external fixation is suitable for most closed tibia and fibul...
