Abstract (en)
[origin: WO2022063390A1] The invention relates to a medical instrument system (1) comprising: a handpiece (7), which has a housing (7a) in which a drive (8) and/or a gearing mechanism is accommodated and which preferably has a housing part (7b) which is or can be attached thereto; and a surgical tool (2), in particular a surgical milling or drilling tool, which is supported on the housing (7a) and/or the housing part (7b) by a plurality of rotary bearings (9, 10) and which is or can be coupled for conjoint rotation and in an axially fixed manner, preferably via a torque-transmission cable (8a), to the drive (8) and/or gearing mechanism so as to transmit a torque from the drive (8) and/or gearing mechanism to the tool (2); wherein at least a first (9) of the rotary bearings (9, 10) in the region of a distal end portion of the tool (2) is connected to the tool (2) to form a unit, and at least a second (10) of the rotary bearings (9, 10) is accommodated in the housing (7a) or the housing part (7b), proximally to at least one first rotary bearing (9), so as to be stationary.
