摘要：
The technical solution relates to medical equipment and can be used in orthopedic operations for bone treatment, in particular in immersion osteosynthesis, in the treatment of osteomyelitis foci, or in surgical treatment of false joints, including the treatment of infected false joints with concomitant bone osteomyelitis. The return bit for processing the bone contains a handle 1, butt 2, a working part 3 equipped with a cutting edge 4. It differs in that the cutting edge 4 on the working part 3 is oriented towards the position of the handle 1. This allows you to use the principle of the reverse hammer when the blow is applied not in the forward direction from the outside of the handle, but in the opposite direction. The butt 2, with respect to the handle 1, is located on the side of the working part 3. The working part 3 consists of a rod 5 with a tip 6. The rod 5 performs the function of a guide onto which the sliding hammer is mounted. A sliding hammer is put on the rod 5 of the working part 3. Apply force to the hammer, move it along the rod 5 until it collides with the butt 2. The hammer hits the butt 2, the force from the impact is transmitted through the rod 5 to the cutting edge 4, the cutting edge 4 cuts into the bone tissue and cuts off a fragment of bone. The technical result is to ensure cleaving bone tissue from the back surface of the bone. This reduces the risk of unintentional damage to soft tissues, spalling of bone fragments larger than required size. The chisel allows you to quickly and safely process the trailing edge (edge) of the bone fragment of the bone, giving it a pointed shape. 13 s.p. f-ly 11 ill.Техническое решение относится к медицинской технике и может быть использовано при ортопедических операциях для обработки кости, в частности при погружном остеосинтезе, при обработке очага остеомиелита или при оперативном лечении ложных суставов, в том числе при обработке инфицированных ложных суставов с сопутствующим остеомиелитом кости.
