Title: HAND-OPERATED FUNCTIONAL HOSE INSTRUMENT
Abstract:
Hand-operated functional hose instrument. The invention relates to a hand-operated functional hose instrument which comprises a tubular functional part and a wire-shaped functional part which extends therein. The invention also relates to an actuating unit designed for detachably coupling to a operating handle element which is arranged on a proximal end portion of the function parts and comprises two actuation parts which can move axially relative to each other and comprise a tubular fixation or a wire fixation. The first actuating part is fixed axially on the operating handle element and the second actuating part comprises a finger-actuated control slide element. According to the invention, the first actuating part (7) comprises a finger-actuated control rotational element (11) and/or a distal cone portion (12) with an axial recess in which the second actuating part (8) can be at least partially inserted, and/or the wire fixation comprises two wire fixation parts (25, 26) which can be rotated counter to each other about a longitudinal axis from a wire release position into a wire clamping position, each having an eccentric axial wire lead-through opening, both wire lead-through openings being arranged axially one behind the other and are flush in the wire release position and are not flush in the wire clamping position. The invention also relates to the use thereof as a medical stone trapping device.
