Problems solved by technology

There are the following defects: the balloon, the inner tube, and the outer tube are formed three times, and then connected into one body by welding. Tube welding, the key points of the process affect each other, and the product performance can only be tested through the finished product, which makes the research and development difficult; at the same time, there are many process control points in the production, resulting in low production efficiency, serious waste of raw materials, and high production costs

Abstract

The invention discloses a vertebral body expansion device and a manufacturing method thereof. The vertebral body expansion device comprises a balloon catheter integrally formed by a balloon body and acatheter body, the balloon catheter is connected with a connecting supporting part used for introducing a contrast agent, the balloon body is located at the first end of the catheter body, and the connecting supporting part is located at the second end of the catheter body. According to the vertebral body expanding device, the integrated forming technology is adopted, a balloon and an outer tubeare combined, an inner tube is eliminated, so that the product structure is simpler, the research and development difficulty is lowered, technological parameters are reduced, the production efficiencyis improved, material waste is reduced, and the production cost is reduced; and the inner tube is not needed, so that the outer tube is thicker, and the pressure resistance of the product is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a vertebral body expansion device. It also relates to a manufacturing method of the vertebral body expansion device. Background technique [0002] In the treatment of vertebral body compression fractures caused by vertebral body destruction, a bone expander (balloon) is inserted into the vertebral body by using skin balloon expansion kyphoplasty. A cavity is formed in the body to be filled with bone cement, which is injected under low pressure, thus greatly reducing the risk of leakage. [0003] The existing vertebral body expansion device adopts an inflatable balloon, a flexible inner catheter and an outer catheter, an elastic support guide wire contained in the inner catheter, and a bifurcated connecting part. Inject liquid or gas into the channel controlled by the valve between the inner tube and the outer tube to inflate the balloon. There are the following defec...
