China's domestic artificial cervical discs face the break of European and American monopoly
Release date: 2014-06-23 China has made new breakthroughs in the field of cervical spine surgery. On the 18th, West China Hospital of Sichuan University released a message that the first domestic artificial cervical disc has been successfully used in surgery, which broke the monopoly of Europe and the United States in the field of cervical spine surgery. Cervical spondylosis is caused by long-term cervical vertebrae strain, bone hyperplasia, or intervertebral disc prolapse, ligament thickening, resulting in compression of the cervical spinal cord, nerve root or vertebral artery. Traditional cervical fusion surgery, although it can treat cervical disc herniation, but after surgery, patients will have long-term inability to move the neck, the overall function of the cervical spine is reduced. Professor Liu Hao, deputy director of the Department of Orthopaedics, West China Hospital of Sichuan University, first introduced artificial cervical disc replacement surgery from abroad ten years ago. After seven years of hard work, Professor Liu Hao and Chuangsheng Group have jointly developed an artificial neck that is more suitable for Chinese people. Intervertebral disc. "Imported artificial cervical discs are designed according to the cervical spine structure of European and American races, and there are two or three percent of Chinese patients who do not match this." Professor Liu Hao said that the model mismatch often affects the effect of replacement surgery. To this end, Professor Liu Hao and his research and development team have optimized the Chinese cervical spine size and developed a more suitable product for the Chinese. On June 10, the first Chinese artificial cervical disc replacement surgery was performed at West China Hospital of Sichuan University. After the operation, the patient recovered well and was able to do some cervical rehabilitation. It is understood that the artificial artificial cervical intervertebral disc uses titanium alloy, high molecular polyethylene and other materials. The previous verification at the German testing center showed that its wear resistance is higher than most imported products. At present, the unit price of imported artificial cervical disc products in China is about 60,000 yuan. After the artificial cervical intervertebral disc production is localized, the unit price will drop by more than 50%. "This will also force imported products to lower prices and benefit Chinese patients." Say. The clinical trial project of domestic artificial cervical intervertebral disc has been approved by the relevant state departments and entered the formal implementation stage. During the implementation of the project, patients with single-segment cervical disc herniation who are suitable for cervical disc replacement surgery will be selected by Huaxi Hospital of Sichuan University for free use. "Research is not to publish articles in academic journals, but to make technology really available to ordinary people." Liu Hao said that domestic artificial cervical discs will be widely used after two years. Source: China News Network Xi'an complex bio-tech CO.,LTD. , https://www.complexpowder.com
