Locking and external fixing device for calcaneal fracture treatment

Abstract

The invention relates to a locking and external fixing device for calcaneal fracture treatment and belongs to the technical field of medical instruments. The locking and external fixing device is an L-shaped hollow flat plate; and thread holes, in which screw nails can be screwed, are formed in the side frame of the L-shaped hollow flat plate. The locking and external fixing device for calcaneal fracture treatment belongs to external fixation, so small trauma and less bleeding can be caused; incision can be shortened by times and is only 4cm; incision complication can be obviously reduced when the external fixing device is along a limb body direction; due to external fixation, secondary operation can be unnecessary for calcaneus removal; secondary operation risk can be avoided and medical expanses can be reduced for patients; the external fixing device can be made from light material such as stainless steel, titanium alloy or aluminum alloy; the locking and external fixing device has small size, light weight and causes small pain for patients, thereby facilitating patient recovery; the locking and external fixing device has small damages, small nail path complications; and operation safety can be improved.

Description

technical field [0001] The invention relates to an external fixation locking and fixing device for treating calcaneus fractures, belonging to the technical field of medical instruments. Background technique [0002] Calcaneal fracture is a common fracture. Surgical treatment is the main treatment method. 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 disadvantage of internal fixation is that the surgical trauma is large and the incision is not easy to heal, so it is easy to cause complications such as infection, and the operation process is complicated, requiring repeated or even multiple operations. Treatment can achieve the purpose of healing. The traditional external fixator is also one of the treatment methods for calcaneal fractures, but the application of the external ...

Problems solved by technology

Internal fixation using steel plates and screws as materials is currently the main clinical treatment method. The disadvantage of internal fixation is that the surgical trauma is large and the incision is not easy to heal, so it is easy to cause complications such as infection, and the operation process is complicated, requiring repeated or even multiple operations. treatment, in order to achieve the purpose of healing

The traditional external fixator is also one of the treatment methods for calcaneal fractures, but the application of the external fixator is greatly limited due to its bulky body, complicated operation, poor fixation effect, and easy loosening.
