Abstract: Disclosed herein is a bone fixation device. The fixation device has a head portion having a conduit and a plurality of pawls formed therein along one side of the conduit; and an elongation strip having a hooked end and a plurality of ratchet teeth formed thereon the body of the strip. The head portion is connected to the non-hooked end of the elongation strip at an angle between 100-170 degrees, and the plurality of pawls of the head portion engage the plurality of teeth when the elongation strip is inserted into the conduit of the head portion to form a loop around the weaken or fractured bone so as to stabilize the weaken or fractured bone.

Abstract: A suction-irrigation head includes a manifold set, one end extending to form a discharge pipe and an intake pipe, an end of the discharge pipe forming a discharge opening, an end of the intake pipe forming an intake opening; a tube including a circumferential wall, intake bores disposed on one side of the circumferential wall, discharge bores disposed on the other side of the circumferential wall; and a separation wall, the interior of the manifold set and the tube being divided by the separation wall to form an intake chamber and a discharge chamber not communicating with each other, the intake chamber, the intake pipe, and the intake bores communicating with one another, and the discharge chamber, the discharge pipe and the discharge bores communicating with one another.
