Technical Field

The invention relates to the technical field of medical instruments, in particular to a novel human skeleton internal fixation system.

Background

Bones are the hard organs that make up the internal bones of vertebrates and function to move, support and protect the body; manufacturing red blood cells and white blood cells; storing minerals. The skeleton is composed of various shapes and has complex internal and external structures, so that the skeleton can keep hard while reducing the weight. One of the components of the skeleton is mineralized skeleton tissue, and the inside of the skeleton is a hard honeycomb-shaped three-dimensional structure; other tissues include bone marrow, periosteum, nerves, blood vessels, and cartilage, and the bones of the human body function as a support for the body and are part of the body's motor system. There are 206 bones in adults. The bones are generally connected by joints and ligaments, and the human body bone internal fixation system is one of the most important treatment means of the existing orthopedic system. The use of intra-skeletal fixation systems for the treatment of bone fractures was first reported in 1775. Through the development of internal fixation system theory and materials science for many years, the pedicle screw and plate/rod system is the most widely and mature internal fixation system for treating orthopedic diseases at present. Due to the diversity of human skeletal systems, the current pedicle screw, plate and rod systems can be mainly divided into two major categories, namely pedicle screw systems for the spine and pedicle screw and plate (intramedullary nail) systems for limb trauma. Due to the huge demand, the bone internal fixation system has huge market economic value.

At present, the prior human skeleton internal fixation has the following defects:

1. the design system and the material research of the prior human skeleton internal fixation system (pedicle screw and plate/rod system) are developed more mature, but the real three-dimensional fixation is not realized clinically, and the problems of difficult use or high complication incidence rate after operation exist in some cases when the systems are used;

2. meanwhile, when a patient with severe scoliosis is fixed in a pedicle screw, the vertebral body sequence is unbalanced due to the severe scoliosis degree, and the pedicle screw sequence is not in a straight line, so that the titanium rod needs to be pre-bent to a certain degree, which may cause unsatisfactory orthopedic effect or increase the risk of internal fixation failure due to increased metal fatigue;

3. in addition, when a patient who is weak uses the internal fixation system, the protruding part of the internal fixation may abrade the skin, which may lead to local necrosis and infection, which may cause physical and mental burden of the patient and affect the operation effect.
