External Fixation Scaffold Components to Promote Bone Healing

Abstract

The invention provides an external fixed bracket assembly for promoting bone healing. The external fixed bracket assembly comprises an external fixed bracket arranged at a bone injury part of a patient, a medicine seepage device which is assembled on the external fixed bracket and is in contact with the bone injury part of the patient, and a bone stimulation device which is assembled on the external fixed bracket and is located between the external fixed bracket and the medicine seepage device, wherein the external fixed bracket comprises a body assembled on the bone injury part and a cover body assembled on the body; the external fixed bracket is provided with an accommodating cavity surrounded by the body; the medicine seepage device is assembled on the body and is located in the accommodating cavity; and the bone stimulation device is assembled in a region, where the medicine seepage device is located, on the body. The external fixed bracket assembly for promoting bone healing can realize filling of medicines through the medicine seepage device and enable the medicines to seep from seepage holes in the medicine seepage device to realize uniform medicine supplying; furthermore, circulation of the medicines is promoted by micro vibration emitted by the bone stimulation device arranged on the body; and meanwhile, blood circulation of the affected part can be accelerated, and healing of the bone at the affected part can be promoted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an external fixation bracket assembly for promoting bone healing. Background technique [0002] Limb injuries accounted for a relatively high proportion of injury sites in trauma patients, and limb fractures were more common. Early reduction and fixation of fractures can effectively control the bleeding at the fracture ends, avoid secondary vascular and nerve damage caused by movement between the broken ends, and effectively reduce the occurrence of serious complications such as fat embolism. At present, the more common external fixation methods are mainly divided into plaster external fixation and splint bandage external fixation. Traditional gypsum fixation has good shaping properties, and the gypsum is very solid after drying, and the fixation is reliable. However, due to the high oppression of gypsum, it is easy to produce compressive ulcers if the time is too long. ...

AI Technical Summary

Problems solved by technology

Traditional gypsum fixation has good shaping properties, and the gypsum is very solid after drying, and the fixation is reliable. However, due to the high oppression of gypsum, it is easy to produce compressive ulcers if the time is too long. In addition, ordinary gypsum has poor air permeability and is prone to eczema , skin allergies and other skin diseases

When the splint is used for fixation, the local mobility of the affected limb is large, and secondary displacement is likely to occur after reduction. At the same time, the excessive pressure of the pressure pad will hinder the local blood circulation, aggravate the swelling of the distal limb, and cause adverse reactions such as pressure sores and nerve paralysis.

In addition, after plaster external fixation and splint external fixation, the plaster and splint need to be removed before the medicine can be applied again. The operation is complicated and may easily cause secondary fractures
