    摘要： A rotational atherectomy device for abrading a stenotic lesion from a vessel of a patient comprises a flexible drive shaft (1) which extends towards a distal end of the device, a distal fluid inflatable support element (3, 3″) located at a distal end of the drive shaft and an abrasive element (5) mounted to the drive shaft proximal to and spaced away from the distal fluid inflatable support element. Both the abrasive element and the distal fluid inflatable support element are rotatable together with the drive shaft and the drive shaft comprises a torque transmitting coil (2) which defines a long lumen of the drive shaft. The distal fluid inflatable support element is formed from a fluid impermeable membrane (9, 9″) that crosses a longitudinal axis (x-x) common to the torque transmitting coil and the lumen of the drive shaft at the distal end of the device, thereby preventing pressurized fluid flowing along the lumen of the drive shaft from entering the vessel in the direction of said longitudinal axis so that fluid has to pass through the fluid inflatable support element, inflating said support element and exiting from the device through an outflow opening (66) in the fluid inflatable support element in a direction different from the direction of the longitudinal axis of the coil and the lumen.

    摘要： The medical handpiece of the present invention has a cutting tool having a flexible shank and a bur provided at the distal end of the cutting tool for cutting an affected area, a tubular sheath for receiving the cutting tool therein, and a handpiece body for detachably holding the proximal end of the cutting tool and transmitting driving force from a drive source to the cutting tool. The sheath and the cutting tool are made flexible for a particular range, with the sheath being plastically deformable and the shank of the cutting tool being elastically deformable. The medical handpiece is further provided with a plurality of bearings arranged in the sheath, first interposed members that are tubular and flexible and arranged proximal to, distal to, and between the bearings, and second interposed members that are tubular and flexible and arranged inside the first interposed members.

    摘要： The invention relates to a medical instrument for cutting biological and especially human tissue, having a hollow cutting tube that can rotate by means of an engine around its longitudinal axis, on whose distal end at least one blade is mounted, as well as with a handle in which the cutting tube is mounted for control purposes. In order to produce a medical instrument for cutting biological and especially human tissue in which the powering of the cutting tube is of simple construction and involves minor losses of capacity, it is proposed with the invention that the engine is configured as a hollow-shaft engine mounted on the cutting tube.
