CATHETER FOR SPINE CORRECTION

摘要

PURPOSE: A catheter for vertebroplasty is provided to complete surgery in a short time and minimize the number of components, thereby saving production cost. CONSTITUTION: A catheter for vertebroplasty includes a shaft(1), a cylinder(3), and a piston(4). The shaft is inserted into a spine through a patient's body, the cylinder is connected to the shaft with a supply hose, and the piston is fastened to the cylinder. A doctor manipulates the piston into injecting air. An iron pin(9) is integrally injection-molded between the inner and the outer diameter of the shaft in order to reinforce the strength of the shaft. The length of the iron pin is identical to that of the shaft, or is two-thirds of that of the shaft.
