Abstract
A manipulation device (20) for a microinvasive medical instrument (10) comprises a recess (47) for receiving a proximal region (72) of an electrically conductive transmission device (70) for transmitting electrical power and at least either a force or a torque to a distal end of a microinvasive medical instrument (10), and a contacting device (50) for producing an electrical contact to a transmission device (70) arranged in the recess (47). The contacting device (50) has a plurality of contact faces (57) for simultaneously bearing on a surface (75) of a transmission device (70) arranged in the intended manner in the recess (47).
Claims20
A manipulation device for a microinvasive medical instrument, the manipulation device comprising:
- a proximal region portion defining a recess for receiving a proximal region of an electrically conductive transmission device for transmitting electrical power and at least either a force or a torque to a distal end of a microinvasive medical instrument;
- and
- a contacting device for producing an electrical contact to the electrically conductive transmission device arranged in the recess, wherein the contacting device has a plurality of contact faces for simultaneously bearing on a surface of the electrically conductive transmission device arranged in an intended position in the recess.
A medical instrument comprising:
- a manipulation device comprising a proximal region portion defining a recess and a contacting device arranged in the recess, wherein the contacting device has a plurality of contact faces,
- a shaft, of which the proximal end is mechanically connected or connectable to the manipulation device,
- an electrically conductive transmission device for transmitting electrical power and at least either a force or a torque from the manipulation device to a distal end of a microinvasive medical instrument to be formed with the manipulation device, the recess receiving a proximal region of the electrically conductive transmission device and the plurality of contact faces simultaneously bearing on a surface of the electrically conductive transmission device arranged in an intended position in the recess.
