Abstract
The utility model relates to a pressable needle cable fixing system for patellar fracture, which consists of a needle body, a steel cable and a guide needle, wherein the needle body and the guide needle are connected with the two ends of the steel cable; the needle body is a solid metal cylinder; and an annular tail hole is formed at the end of the needle body, which is not connected with the steel cable. The pressable needle cable fixing system has the advantages that compared with the common hollow forcing screws or nail cables sold in the existing market, the pressable needle cable fixing system is simple in assembly and can achieve the purpose of pressing the broken end of a fractured bone in the assembly process; when a tension band conducts fixing, the pressure on all parts of a needle cable is balanced as the needle cable slides, so as to generate an overall pressing effect; as the system is provided with no sharp structures such as threads, incision between implants or incision of the implants to peripheral tissues can be avoided to the greatest extent; as the needle cable is slidable, the tension band of the steel cable conducts the fixing and pressing, the pressure on all the parts of the needle cable are dispersed uniformly; and the cracked risks of the implants are reduced.
