Germany's win Chong Industrial Group is committed to the development of a new type of high strength composite material with biodegradability, and its products are expected to replace the metal stent. In the treatment of fractures and other injuries, the internal fixation support is indispensable. Today, the use of more than metal materials, after the end of treatment need to be taken out by additional surgery. In contrast, the new material to win a new material to eliminate the worries. With the recovery of bone, the material which is made of a variety of polymers and natural bone will gradually be absorbed by the body. At present, this very forward-looking research has taken a solid first step. Medical equipment project leader Kalaw said in an interview: "now our materials do not have enough strength, can not be used in large load-bearing bones." So, researchers are trying to increase the strength of the material by adding inorganic substances, including calcium phosphate and its derivatives. "In addition to the increase in strength, these substances can also help improve the biocompatibility of the material, which can be absorbed by the newly formed bone tissue in vivo." Through 3D printing technology on the inside of the fixed stent tailored to win a new material to make this idea become possible, researchers also hope to achieve this goal to make their own a force.
