Visual elastic intramedullary nail for children long bone fracture

Abstract

The invention relates to a visual elastic intramedullary nail for children long bone fracture. The visual elastic intramedullary nail comprises an elastic intramedullary nail body, an endoscope and anendoscope fixing device, wherein the elastic intramedullary nail comprises a head end nail, a tail end nail and an elastic nail body connected with the head end nail and the tail end nail, the elastic intramedullary nail is of a hollow structure, and the endoscope penetrates through the hollow structure and is detachably connected with the head end nail through an endoscope fixing device. The elastic intramedullary nail is combined with the endoscope, so that the problem that intramedullary nail implantation can only be performed through blind operation in the current operation is solved, theproblem that the implantation effect can only be detected through experience or X-ray photographing after blind operation is solved, the simplicity of the operation is improved, the operation time isgreatly shortened, and wound to an operation part of a patient is also avoided. Besides, through the endoscope fixing device, the endoscope can be directly pulled out after the elastic intramedullarynail is placed in the endoscope fixing device, the endoscope can be reused only by selecting the corresponding elastic intramedullary nail, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the field of elastic intramedullary nails, in particular to a visible elastic intramedullary nail for children with long bone fractures. Background technique [0002] The elastic intramedullary nail for children is based on the evolution and improvement of the intramedullary nail used in the treatment of adult long bone fractures. It is a metal round bar of titanium alloy with a special elbow, which has a certain degree of elasticity. Elastic intramedullary nails are mainly used for long bone fractures in children, including femoral shaft fractures, tibial shaft fractures, and humeral fractures in children. In the past, open reduction and plate fixation were required for the treatment of such fractures, which caused large surgical trauma and slow healing. With the in-depth study of children's fractures and the re-understanding of the fixation and stabilization system, elastic intramedullary nails are widely used in long bone f...

AI Technical Summary

Problems solved by technology

[0004] The mechanical principle of the elastic intramedullary nail is simple and easy to understand, but in operation, since the intramedullary nail needs to be manipulated to pass through the fracture, it is very easy to operate blindly due to the inability to determine the position of the bone marrow cavity at the fracture. Penetration of inner nails is likely to cause trauma to surrounding tissues, and the operation is extremely inconvenient, which increases the operation time and the time for patients to be exposed to X-rays during the operation, causing adverse effects on the patient's body
