The invention discloses a tantalum rod for operation. The tantalum rod has hollow perforation through the length direction of the tantalum rod, an elastic sheet is arranged at the end of the perforation, and a micro-hole is arranged on the elastic sheet. Under natural circumstances, the elastic sheet is depressed at the head end of the perforation, and there are more than two branches in the middle of the perforation. The terminal opening of the branch pipe is located on the side wall of the tantalum rod. An annular groove is arranged on the inner wall of the end through the hole, and the elastic card is clipped in the annular groove. The invention has elastic pieces at the end of the tantalum bar, which are concave under natural conditions. First, the broken bones are placed in the groove, then the broken bones are stuffed into the drill hole, and then the broken bones are stuffed into the drill hole from the head through the hole. The elastic pieces are resisted by the elastic pieces, and the broken bones on the elastic pieces can contact with the inner surface of the bottom of the drill hole. At the same time, the broken bones in the branch pipe will be pressed against the inner surface of the side wall of the drill hole. It proves that the central part of the tantalum rod contacts with healthy bone tissue, improves the success rate of the treatment of the tantalum rod, and wraps a protective frame around the outer part of the tantalum rod. This design can ensure that the tantalum rod will not break when it is implanted into the pre-embedded hole, and ensure the integrity of the tantalum rod.

一种用于手术的钽棒
本专利技术涉及一种手术器械。
技术介绍
人体的股关节是非常重要的部件,当髋关节发生病变,比如关节坏死的情况下,需要取出坏死的组织然后向股关节内填充一些人造材料。目前采用的填充材料多是多孔钽材料。手术时,先用电钻在股关节上钻孔,然后将孔内坏死的关节组织取出,再将钽棒填入孔内,最后用健康的碎骨组织填充缝隙并缝合伤口。在使用钽棒进行治疗的过程中,钻孔的大小要求和钽棒的大小相一致,在实际的手术过程中,钻孔的孔径和深度是大于钽棒的,这样就会造成钽棒的顶端和钻洞的底部不能接触,在钽棒植入后,不能发挥骨诱导作用,造成治疗的失败。同时在植入的过程中,钽棒需要承受较大的力,有些钽棒就会被扭断或者在最后填充碎骨的时候被敲断。
技术实现思路
