PURPOSE: To promote the transplantation of an artificial prosthesis into a bone by suppressing the maximum dimension of a particle of a living bone or a bone having a growth factor within a specific scope and carrying out the atomization of the particles on the artificial auxiliary mounting tool and the treatment of the bone at low temperature in the atmosphere. CONSTITUTION: When a lever 70 and a pivot pin 72 are rotated to the right side of an axis to operate a bone spray gun 10, a bearing 58 moves upward, and an attachment part 54 of a base 50 also moves upward. A bottom part 48 of a slide passage 32 which is in contact with the bearing 58 also moves upward at the same time. Next, an upper part 46 of the slide passage 32 moves upward to cut away a bone particle 108 in a hollow hole 34 into a thin part, and this thinnly cut part of the bone particle 108 is pushed out into a space 107 between an air jet hole 41 and an outlet hole 44 by the slide passage 32. These bone particles are fed out from the gun through the outlet hole 44 by jetting air while the hole 34 is covered with the slide passage 32. Next, when the lever 70 is opened, it returns to its original position by a spring 60 and moves until the bone particles 108 reach a covering 78. Consequently, it is possible to improve the transplantation of the artificial prosthesis in the bone and the treatment of a broken bone and a cut section of the bone. |
