摘要：
The utility model relates to medicine, namely to traumatology and orthopedics, and is intended for bone formation channel different magnitudes and directions, and the sampling of bone grafts cylindrical shape as a bar or stick, of different diameters. Performing different in magnitude and direction, the channels in the bone tissue for use in treating formations tendon strain stop, and in the treatment of various orthopedic diseases: pseudoarthrosis of long bones, intraosseous cysts, Perthes disease, etc. Summary of the utility model is that the hollow cutter for forming the channels and the sampling of bone bone grafts comprises a cylindrical tube with cutting teeth on the end surface of the working end, a handle - at the opposite end, and a cylindrical guide having a through axial channel mounted inside the tube. The outer diameter of the cylindrical cutter shank is formed by landing size standard drill chuck. The shank is equipped with an axial through hole. At the end of the cylindrical guide having an axial passage for K-wire facing the cutter shank, formed by a pusher jack. Hole diameter corresponds to the diameter of the axial through hole of the shank cutter. Hollow milling cutter is formed as a set with different outer and inner diameters and lengths, and the guides for the respective sizes, all cutter shafts have the same diameter. Hollow milling pusher has a cylindrical rod with a diameter equal to the diameter of the axial through hole cutter shank, on the end of the rod configured thickening on the side surface which the handle is installed. 2 ZP f ly-1-yl.Полезная модель относится к медицине, а именно к травматологии и ортопедии, и предназначена для формирования костных каналов различных величин и направлений, и забора костных трансплантатов цилиндрической формы в виде столбика, или карандаша, разных диаметров.
