A tool for a bone implant includes a rod and an adaptor. The rod includes a coupling portion having a through-hole. The rod further includes a measuring arm connected to the coupling portion and a force applying arm connected to the coupling portion. The measuring arm includes a first extension section having a first indicator portion, and the force applying arm includes a second extension section having a second indicator portion. The force applying arm is elastically deformable away from the measuring arm to displace the second extension section relative to the first extension section. The adaptor is coupled in the through-hole and includes an outer ring and an inner ring. The outer ring is rotatable relative to the inner ring in a single direction.

Tool for bone implant

A tool for a bone implant includes a sleeve and a transmission rod including a transmission member disposed on an end of a shaft. Another end of the shaft is located outside of the sleeve. The transmission member is received in the sleeve and includes a first compartment and a plurality of first teeth surrounding the first compartment. A drilling rod includes a second compartment and a plurality of second teeth surrounding the second compartment. A coupling portion is disposed between the second compartment and a bit. The coupling portion is coupled with the sleeve. The bit is located outside of the sleeve. Two magnets are disposed in the first and second compartments, respectively. Two same poles respectively of the two magnets face each other.

A fibrocartilage suturing device is provided to solve the problem where the conventional procedure of the surgery is inconvenient. The fibrocartilage suturing device includes a tube assembly, a tubular member, and an anchor. The tube assembly extends through the tube assembly and includes an insertion section. The movement member is coupled with the tube assembly and includes a thrust rod extending through the tubular member. The anchor is located at one end of the thrust rod and includes a body and at least two wings connected to the body is able to be folded and unfolded relative to the body. The body of the anchor is connected to an end of a thread. Another end of the thread is connected to the tubular member.
