A pneumatically powered surgical handpiece suitable for a pencil-type handpiece configuration in which the pressurized fluid inlet is axially directed relative to the handpiece body. Fluid is directed through a dispersing section from an axial direction to a radially outward direction against the interior of a hollow cylindrical turbine body provided with a plurality of circumferentially arranged and longitudinally extending semi-circular channels adapted to receive the fluid flow and redirect it proximally through an annular exhaust channel situated annularly about the fluid inflow conduit. An output shaft is integrally formed with the turbine body and extending distally therefrom and a surgical instrument may be attached to or integrally formed within this output shaft. The invention also resides in a method for fluidically driving a surgical handpiece and lends itself to a method of producing a disposable fluidically driven surgical instrument.

Pneumatic surgical handpiece and method

A rotatable shaver having inner and/or outer non-metallic elongated blades for use in endoscopic surgical procedures. In one embodiment a rotatable, elongated non-metallic inner tubular member is disclosed for use with a non-rotatable elongated metallic outer tubular member, the inner member having a flexible, non-metallic tubular body, a proximal hub and a distal tip provided with a cutting tip having a cutting edge formed therein. The elongated tubular body of the inner member is mechanically joined at its proximal end to the hub and at its distal end to the cutting tip. The mechanical connection enables the transmission of torque from the proximal end of the inner member to the distal end while sufficiently holding the tip, tube and hub assembly together to enable insertion and removal of the assembly into and from the outer member.
