FIELD: medical engineering. SUBSTANCE: proposed apparatus comprises set if instruments for treating bones and electromagnetic hand hammer. Inventive novelty of apparatus resides in assortment of instruments used, viz. straightosteotomes-broad, medium-size and narrow ones; grooves osteotomes-broad, medium-size and narrow ones; raspatories-straight and curved ones; pricks-round, square and triangular ones. All of above-mentioned instruments have same length and include square-shaped shank portion to match socket in square-shaped guide sleeve in insulator insertable into fastening assembly of electropercussive device to be fixed therein. As electropercussive device is connected to electric current supply network, it administers blow transmitted to specific instrument to be used, thus setting it into motion. EFFECT: greater efficiency in treatment of bone tissues. |
