  • Such instruments are used in both human and veterinary medicine and are known, for example, from DE-40'29'676.
  • This document discloses a jigsaw for surgical purposes, in which a gear is arranged in a cylindrically shaped handpiece, which converts a rotational movement of the drive into a combination movement.
  • Combination movement comprises on the one hand an oscillating movement over which a pendulum movement is superimposed.
  • an object of the present invention to provide an instrument which can be safely and precisely guided by the operating doctor.
  • an instrument is to be created which is adapted to the operating environment and does not lead to rapid fatigue of the surgeon during use, i.e. is non-slip in the surgeon's hand.
  • the instrument should be easy to clean and maintain.
  • a medical instrument with the features of the present claim 1, and in particular by an instrument which has a handpiece with an inner chamber in which an electromotive drive for oscillating or rotating tools is attached, the handpiece having an outer surface, that is spanned by three handle surfaces lying parallel to a central longitudinal axis, such that the outer surface has an essentially triangular cross section.

  • This can be in the form of a rechargeable battery, which is inductively rechargeable at best, a battery or a power pack.
  • This power supply can be accommodated in the handpiece, in the inner chamber or in the pistol grip.
  • the instrument according to the invention can be guided safely and precisely, does not lead to the surgeon's fatigue when in use and, because of the pressure-tight inner chamber, can be cleaned and / or serviced in a simple manner, in particular the present instrument does not need for cleaning / sterilization to be more disassembled.
  • the shape of the handpiece according to the invention also proves to be particularly advantageous if, during the operation, the handpiece is put aside for a short time because it remains in place, i.e. cannot roll away.
