摘要：
A bone implant drill is presented to reduce the high temperature caused by prior bone implant drill while using. This bone implant drill comprises a sleeve, a bearing, a driving rod, a drilling rod and an elastic member. The driving rod has a rod member and a driving member, with the rod penetrates through the bearing, with the driving member set at one end of the rod member and in the sleeve, with another end of the rod member protrudes the sleeve. The drilling rod has a position member and an engaging member inside the sleeve. The elastic member set in the sleeve, with one end of the elastic member encases the engaging member and abuts against the position member, with another end of the elastic member encases the driving member and abuts against the bearing. The driving member is able to engage with the engaging member, or be shoved off from the engaging member.一種骨植入物用鑽頭,用以改善目前骨植入物用鑽頭使用時易產生高溫的問題。本發明的骨植入物用鑽頭包含一套筒、一軸承、一傳動桿、一鑽削桿及一彈性件;該傳動桿具有一桿件及一傳動件,該桿件貫穿該軸承,該傳動件設於該桿件的一端並位於該套筒中,該桿件的另一端穿出該套筒;該鑽削桿具有一定位件及一嚙合件,該嚙合件位於該套筒中;該彈性件設於該套筒中,該彈性件的一端套於該嚙合件外並抵接該定位件,該彈性件的另一端套於該傳動件外並抵接該軸承,該傳動件及該嚙合件可相互嚙合,或由該彈性件撐開而分離。1‧‧‧套筒1a‧‧‧第一端1b‧‧‧第二端11‧‧‧內環凸緣2‧‧‧軸承21‧‧‧外環22‧‧‧內環3‧‧‧傳動桿31‧‧‧桿件32‧‧‧傳動件321‧‧‧抵靠肩部322‧‧‧第一嚙齒3221‧‧‧外表面3222‧‧‧內表面3223‧‧‧側向表面4‧‧‧鑽削桿41‧‧‧切削刃42‧‧‧定位件421‧‧‧抵接肩部43‧‧‧嚙合件431‧‧‧第二嚙齒4311‧‧‧外表面4312‧‧‧內表面4313‧‧‧側向表面5‧‧‧彈性件6‧‧‧限位環圈
