Fixing steel plates with nails is the “standard” in traditional surgical treatment for patients after fractures. However, what makes the patient even more painful is that after recovery, a second operation is performed to remove the nail plate. In the future, the pain of this repeated operation will become history. A few days ago, researchers from Changchun Saint-Boma Biomaterials Co., Ltd. told reporters that after continuous innovation and breakthroughs, bone nail bone plates made of new polylactic acid materials can completely replace metal steel nail steel plates. After being implanted in the human body, it can be automatically excreted through the body's metabolism as the body heals, eliminating the need for secondary surgery.
"The product uses a new type of biodegradable material of polylactic acid." Zhuang Xiuli, a researcher at Changchun St. Boma Biomaterials Co., Ltd. revealed that the so-called polylactic acid is formed by refining starch raw materials from renewable plant resources and transforming them with modern science and technology. New polymer materials. This material is highly safe for the human body and can be absorbed and metabolized by human tissues.
Polylactic acid new biodegradable materials have long been monopolized by foreign countries. In order to realize the localization of technology at an early date, the scientific research staff of "St. Boma" has devoted themselves to studying for 12 years. At present, it has developed and obtained more than 30 types of raw materials and products. It has completed the only one in China that meets the requirements of "good manufacturing standards" and has a large variety of scales. The production line for the production of medical polylactic acid materials has an annual output of more than 10 tons, and a production line with an annual output of 100,000 sets of absorbable bone screws and absorbable bone plates has achieved independent innovation in high-value medical devices.
"St. Boma" also adopts bionic design to develop artificial bone products with high mechanical strength and three-dimensional porous scaffold structure. This product is suitable for bone defects caused by trauma, tumors and iatrogenic reasons in any part of the human body. After implantation in the human body, artificial bone is gradually degraded and absorbed while new bone is generated, and autogenous bone regeneration is achieved. At the same time, it can stimulate the rapid growth of osteoblasts to promote bone healing, reduce patient pain, and speed up the healing process.
"With the technical support team of the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences," St. Boma "is continuously conducting research and development around polylactic acid medical polymer materials and absorbable medical device products." Zhuang Xiuli said that "St. Boma" has now It has more than 40 product core patents. The absorbable bone screws and absorbable bone plates have obtained the three types of medical device product registration certificates issued by the State Food and Drug Administration. The product performance and preparation technology have reached the international advanced level.
