Locking and external fixation device used for treatment of tibial fractures

Abstract

The invention relates to a locking and external fixation device used for treatment of tibial fractures, pertaining to the technical field of medical equipment. The device comprises a rectangular frame body and multiple screws. Multiple threaded holes are transversely formed in the rectangular frame body. The screws are screwed into the threaded holes. The threaded holes in the frame body match threads of the screws so that the effect of connecting the frame body with the screws is achieved. The locking and external fixation device used for treatment of tibial fractures has following beneficial effects: the locking and external fixation device belongs to the concept of external fixation and therefore a wound is small with little bleeding; a cut is reduced by times and only 3 to 4 cm in size and the scar is small and attractive; operative complications are increasingly reduced; due to the external fixation, the risk of a secondary operation is lowered; medical cost is saved for a patient; the device is made by light-weight material such as stainless steel, titanium alloy and the like; compared with a conventional external fixation frame, the frame body of the locking and external fixation device is small in size and low in weight and cause little harm to a patient and help the patient recover; damage to a pin track is little; complications of the pin track are fewer; the device is not easily loosened and loses efficacy; and safety of the operation is enhanced.

Description

technical field [0001] The invention relates to a locking external fixation device for tibial fracture treatment, which belongs to the technical field of medical instruments. Background technique [0002] Tibial fractures are common fractures. Surgical treatment is one of the main treatment methods. The purpose of treatment is to fix the fracture site. There are two kinds of fixation methods: internal fixation and external fixation. Internal fixation using steel plates and screws as materials is currently the main clinical treatment method. The disadvantages of traditional internal fixation are large surgical trauma, long incision, and obvious scars. After the fracture heals, the internal fixation plate is located under the skin, which is very obvious. , and often requires secondary surgery to remove it; due to the many open injuries of tibial fractures and poor soft tissue conditions, the difficulty of internal fixation increases and the risk of surgery is high. However, t...

Internal fixation using steel plates and screws as materials is currently the main clinical treatment method. The disadvantages of traditional internal fixation are large surgical trauma, long incision, and obvious scars. After the fracture heals, the internal fixation plate is located under the skin, which is very obvious. , and often requires a second operation to remove it; due to the many open injuries of tibial fractures and poor soft tissue conditions, the difficulty of internal fixation increases, and the risk of surgery is high

However, the traditional external fixator is often unable to wear trousers due to its bulky body, complicated operation, poor fixation effect, and easy loosening. Therefore, the traditional external fixation is only limited to open injuries and orthopedics in the treatment of tibial fractures. Lengthening surgery greatly limits the scope of application of external fixation
