Component-based thoracolumbar anterior internal fixation system

Abstract

The invention discloses a component-based thoracolumbar anterior internal fixation system, and relates to the technical field of medical apparatus and instruments. The problem that common implants arehigh in price, and products have the defects that the products are monotonous, the process is rough, and most products adopt stainless steel materials are solved. According to the technical scheme, the system is characterized by comprising mounting pads, fasteners screwed into a vertebral body, a connecting component and locking blocks; mounting grooves are formed in the mounting pads, the two sides of the connecting component are installed in the mounting grooves through matching; a main mounting column is arranged on each mounting pad; the fasteners penetrate through the connecting component and then are in threaded connection with the interiors of the main mounting columns; the locking blocks are in threaded connection with the outer walls of the main mounting columns and abut againstthe side face of the connecting component; the purpose of being easy and convenient to operation in surgery is achieved, notches of an internal fixation device are effectively reduced, the risk that high notch implants affect other organs or tissue on the front edge of the vertebral body is reduced,the overall applicability is high, the application range of the product is greatly increased, and the purpose of having the high economical practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a component type thoracolumbar anterior internal fixation system. Background technique [0002] With the changes in human living habits and styles, spinal fractures, tumors, infections and degenerative diseases related to spinal diseases frequently occur. For the treatment of the above diseases, although a large number of new technologies and methods are constantly emerging, for patients with more serious conditions, the choice of treatment is still biased towards surgical treatment. In the surgical reconstruction of spinal diseases, it is usually divided into anterior surgery and posterior surgery. Lesions were treated after excision of the board. These two surgical methods have their own unique advantages and indications, and there is no such thing as better or worse. [0003] However, because the anterior thoracolumbar surgery approach is more complicated than the p...

Problems solved by technology

[0004] However, due to various reasons of the current anterior thoracolumbar surgery, its development lags behind that of the posterior surgery. At the same time, the research and development and production of the anterior implant products also lag behind the posterior implant products

At present, the anterior spinal internal fixation products used in clinical practice in China mainly come from the internal fixation devices produced by foreign manufacturers. These implants mainly refer to the anatomical data of foreigners during the development process, so in the process of product design As a result, the product is not suitable for the anatomical characteristics of the Chinese people and the operating habits of the chief surgeon, and the price of the implant is quite expensive, resulting in a certain degree of waste of medical resources. However, some domestic products generally have a single product, rough workmanship, and a large number of implants. Using stainless steel materials and other shortcomings, or even directly using the posterior screw-rod system to carry out anterior surgery, this simple and rough method is not suitable for the rapidly developing spinal implant industry
