Huaxi brand artificial cervical disc placement

Release date: 2014-06-26

On June 10, 2014, it was a date worth remembering in the history of cervical spine surgery in China. On the morning of the same day, with the introduction of the first domestic artificial cervical disc Pretic-I in the cervical vertebra of the patient, Professor Liu Hao, deputy director of the Department of Orthopaedics of Huaxi Hospital, has created the Chinese creation and Huaxi brand in the high-end cervical vertebrae insertion products.

It is reported that the artificial intervertebral disc is a combination of more than 20 years of cervical vertebra surgery experience. It is aimed at the Chinese cervical anatomy and cooperates with the creation group. After 7 years, the research and development is more suitable for Chinese. Artificial cervical intervertebral discs have completely independent intellectual property rights, breaking the monopoly of Europe and the United States in this field, and have epoch-making significance.

Traditional cervical fusion surgery, although it can treat cervical disc herniation well, but the patient's neck can not move for a long time after surgery, the overall function of the cervical vertebra is reduced, and the cervical disc of other parts may be secondary in the long-term. In order to solve this series of problems, Professor Liu Hao took the lead in introducing artificial cervical disc replacement surgery from Huaxi Hospital ten years ago. Over the past ten years, he has completed more than 300 patients with surgical treatment, and achieved good results and accumulated valuable. experience of.

At 8 am on June 10, 2014, Professor Liu Hao led the team members and started surgery with the cooperation of the nursing and anesthesia team. The patient undergoing surgery was a 39-year-old man who had suffered from cervical disc herniation for several months. The patient's prominent neck 5/6 intervertebral disc directly oppresses the left nerve, causing pain in the neck and shoulders, obvious numbness in the palms and three fingers, and severely affecting the patient's sleep when the symptoms are severe, greatly reducing the patient's life. Quality, miserable.

The operation firstly achieves precise positioning of the diseased intervertebral disc under X-ray fluoroscopy, and finely operates along the delicate nerve tissue, carefully and carefully removing the entire diseased disc. Professor Liu Hao's rich experience in cervical disc replacement surgery, combined with tailor-made products based on the characteristics of the Chinese cervical spine, is a perfect combination of skilled surgery and high-tech products. In just one hour or so, the cervical disc of the patient was completely removed, and a new artificial intervertebral disc was successfully replaced. After the operation was successfully completed, the patient woke up, and the original neck and shoulder pain and upper limb numbness symptoms were almost completely relieved immediately, and a satisfactory short-term effect was obtained. After a one-week recovery period, the patient's current surgical incision has healed, and the incision with intradermal cosmetic sutures is difficult to notice without careful observation. The cervical vertebra moves freely in all directions, and the patient feels like he is never sick.

Localized products are low price and high quality

At present, the domestic market is all imported artificial intervertebral disc products, the single price is more than 50,000-60,000 yuan. Titanium alloys, high molecular weight polyethylene and other materials used in domestically produced artificial intervertebral discs are of the same quality as imported products. Moreover, previous tests conducted at the German Testing Center showed that its wear resistance is higher than most imported products. After the localization of the product, the unit price will drop by more than 50%, and the cost will be at least 3-4 million yuan.

Localized products are more suitable for Chinese people

The imported artificial intervertebral discs are from Europe and the United States, and are naturally designed and produced according to the cervical vertebra structure and size of European and American races. In clinical application, it is often found that the imported intervertebral discs are not well fitted to the cervical vertebrae of the Chinese people. It is necessary to dress the bones of the cervical vertebrae more and more in the operation, which increases the difficulty and risk of surgery, and is suspected of “cutting the feet”. The domestic artificial intervertebral disc is optimized for the special cervical vertebra size of the Chinese people. The same specifications of the product, the domestic intervertebral disc will be more suitable for the Chinese cervical vertebrae, more suitable for Chinese people.

Domestic artificial cervical intervertebral disc has several inventions and creations

In view of the problems found in the use of imported artificial cervical intervertebral discs and long-term follow-up patients, Professor Liu Hao's Huaxi medical team and the engineering team of the Genesis Group not only have the structure, shape and size design of the domestic artificial intervertebral disc Pretic-I. It changed, and it was also innovative in the placement tool. It also found that the problem was repeatedly improved by simulating the surgery on the corpse, and finally tempered a set of advanced and applicable products. Among them, the key design has obtained several patent protections in the country.

The clinical trial project of domestic artificial intervertebral disc Pretic-I 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 eligible for cervical disc replacement surgery can choose to use the domestic intervertebral disc free of charge.

Vegetable Juice Powder

Vegetable Powder is dried and dehydrated from vegetable raw materials, and then further crushed; Or first beating, then evenly spray dried powder of vegetable pellets. 1] Vegetable powder is an extension of dehydrated vegetables.

Characteristic

The advantages of processing fresh vegetables into vegetable powder are: low moisture content, can prolong the storage period and reduce the costs of storage, transportation and packaging; The utilization rate of vegetable powder processing raw materials is high, especially there are no strict requirements on the size and shape of raw materials, which widens the application range of vegetables. Research shows that vegetable powder can be applied to almost all fields of food processing, can be used to improve the nutritional composition of food, improve its color and flavor, and can replace the use of artificial pigments in today's society, which has brought protection to the health of our consumers.
