Abstract: A surgical saw apparatus, includes: A) a housing; B) a drive unit with a drive axle having a central axis; C) a deflection device, including: a connecting rod that is arranged movably in the housing, with a longitudinal axis, with a rear section and with a front section with members for a fixation of a sawblade; an eccentric shaft with at least one first section, which is arranged coaxially with the central axis of the drive axle and is connected with the drive axle, and with a second section which is eccentric relative to the first section, wherein the rear section of the connecting rod is a bearing for the eccentric second section of the eccentric shaft, and the front section of the connecting rod is a fixation device for a sawblade; and a guiding device for the connecting rod, wherein D) the guiding device includes first members for a limitation of a movement of the connecting rod, which are movable relative to the housing and which force a translational movement of the connecting rod coaxially with the lo

Abstract: The invention is based on a tool device, in particular hand-held tool device, for use in a surgical method, comprising a tool receptacle, an operating unit, a torque limitation unit, a torque transmission unit and a magazine unit. The torque limitation unit is arranged between the operating unit and the tool receptacle and comprises a plurality of torque limitation elements which are provided to be destroyed when a given torque is exceeded. The magazine unit is provided to exert a thrust force onto the torque limitation elements for introducing them one by one into the torque transmission unit, and the torque limitation unit is provided to respectively receive a torque limitation element and to destroy it when the given torque is exceeded, wherein the torque limitation elements are arranged on a rotary working axle of the tool receptacle.
