摘要:
The invention relates to a laser handpiece 1, an exchangeable fiber-optic insert 10, and a control unit 70 therefor. The laser handpiece 1 comprises a optical waveguide 35, which is connected to a light coupling site in a base member 21 and in which the application element 10 for laser light is exchangeably attached to the base member 21. The base member 21 is mounted in a sleeve-type grip 3 for axial displacement therein. The light guide 10 can be wound around a control device 70 which has an annular gap 73 for this purpose and a lower housing part 75 which is offset from an upper housing part 74. An exchangeable fiber-optic insert 10, 27 acting as an application element is provided with a sleeve 80 serving as protection during transportation and as an assembling tool.

A medical instrument for treating biological tissue comprises a housing (2), a pressure wave generation means (4) and a transmission means (8) for coupling the unfocused pressure waves into the body of living beings. The transmission means (8) comprises a pressure chamber (12) having an inlet and an outlet end, the pressure chamber (12) containing a liquid (14) into which pressure waves from the pressure wave generation means (4) can be coupled, which pressure waves can be transmitted to a membrane (16) arranged at the outlet end of the pressure chamber (12) which membrane (16) couples the pressure waves transmitted from the liquid unfocusedly into the biological tissue.

A device for driving a wire pin, and in particular a Kirschner wire, into bone material, comprising a propelling device that acts upon the wire pin which may be inserted into the device from the free front end thereof, said propelling device being driven by periodically repeated impact strokes applied thereupon by an impacting member. The propelling device acts upon the wire pin without any clamping means being involved, which is achieved by the propelling device being designed as a transmitting member against which the free end face of the wire pin may evenly abut and which may transmit the impact strokes of the impacting member as impact pulses into the wire pin through the free end face thereof, with the impact pulses propagating through the wire pin as periodic compression waves so that the wire pin is successively driven into the bone material.

A metallic flexible probe for use in shock wave lithotripsy is provided next to its head portion and approximately at a transition to an adjoining initial length of the probe with a rated break point for causing without any disturbance of the energy flow along the length of the probe as optimized by different dimensional and material chracteristics of the probe a fracture at a position which most presumably will not lead to harmful injuries of the patient and to no damages of the surrounding lumen of the endoscope which is used in combination with a lithotripter.
