Electric motor driven tool for orthopedic impacting

An orthopedic impacting tool comprises a motor, an energy storage means, a striker, and an anvil. The motor stores energy in the energy storage means and then releases it, causing the striker to apply a controlled force on an adapter to create a precise impact for use in a surgical setting. The tool may further comprise a combination anvil and adapter. The tool further allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of a broach, implant, or other surgical implement from the opening. An energy adjustment control of the tool allows a surgeon to increase or decrease the impact energy. A light source and hand grips improve ease of operation of the tool.

TOOL AND TOOL HOLDER FOR MANUALLY-OPERATED TOOLS

The clamping shank 1 of a chisel-cutting and/or percussion boring tool bits comprises stop faces effective in axial direction and in circumferential direction. Entrainment faces 2, open towards the free end of the clamping shank 1 are located upstream of these stop faces in direction of the cutting area. The radial dimension r of the essentially radially extending entrainment faces 2 is greater than their axial dimensions a. In cooperation with an appropriately designed tool bit receptacle, the entrainment faces 2 can carry such a large share of the torque, that the stop faces are effectively relieved or unloaded.

SAFETY ARRANGEMENT FOR DRIVING TOOLS

A railroad spike driving tool (30) is adapted to be inserted by its shank (22') for cooperation into hand-held hammer machines of the type comprising a machine housing (10) with a cylinder (11), in which a reciprocating drive piston (14) via gas cushion in a working chamber (12) repeatedly drives a hammer piston (15) to impact on the shank (22') during spike driving. Forward sudden displacement of the shank (22') causes the hammer piston (15) to perform a forward blow in the void and come to rest. If the tool (30), as a result of the last impact and simultaneous sideward shifting of the machine, happens to hit against the rail, a safety spring (36), pre-stressed between a rearwardly facing shoulder (34) on the tool (30) and the machine housing (10), prevents the tool (30) from bouncing back into the machine and thus from being hit by said hammer blow in the void or from releasing a new blow. Possible injury to the operator is thereby avoided.

Breaking apparatus and tool

파괴 장치는 충격 장치(1)와 그것의 축 연장부에 있는 공구(3)를 포함하고, 충격 장치에 속하는 충격 피스톤(2)은 공구(3)로 충격을 전달한다. 축 방향에서, 만약 공구의 이동이 충격 방향(A)으로 미리 정하여진 이동의 범위(B)를 초과한다면, 공구의 이동은 스토퍼 부재(15)에 의해 제한된다. 상기 스토퍼 부재(15)는 탄성 재료로 만들어진 부품(piece)이고, 공구와 지지 표면(16) 사이의 공간에 배치된다. 공구가 정지되는 동안, 스토퍼 부재를 위한 공간의 수용력이 감소하고, 부재는 압박을 받는다. 공구 이동의 효과에 의해서, 상기 스토퍼 부재는 그 단면 중심 축(21)을 중심으로 회전하고 동시에 감소하는 공간에서 그 단면 형상을 바꾼다. 또한 본 발명은 상기에 기술된 파괴 장치에서 사용되는 공구에 관한 것이다. The breaking device comprises an impact device 1 and a tool 3 at its axial extension, the impact piston 2 belonging to the impact device transmits an impact to the tool 3. In the axial direction, if the movement of the tool exceeds the range B of the movement predetermined in the impact direction A, the movement of the tool is limited by the stopper member 15. The stopper member 15 is a piece made of elastic material and is disposed in the space between the tool and the support surface 16. While the tool is stopped, the capacity of the space for the stopper member is reduced and the member is pressed. By the effect of the tool movement, the stopper member changes its cross-sectional shape in a space that rotates about its cross-sectional center axis 21 and simultaneously decreases. The invention also relates to a tool for use in the demolition apparatus described above.
