Medical Instrument For Cutting Off Tissue And Cartilage From A Human Or Animal Body

摘要

A medical instrument serves for cutting off tissue and cartilage from a body. It comprises an outer shaft having at least a first window in a distal end area thereof. A hollow inner shaft is received within the outer shaft and can be rotated about a longitudinal axis of the outer shaft. The hollow inner shaft has at least one opening cooperating with the at least one window of the outer shaft in a cutting action when turning the inner hollow shaft. A further window is provided in the distal end area of the outer shaft which further window is surrounded by a curette having a separating edge. Tissue and cartilage separated by the curette can be cut into small pieces by the cutting edges of the rotatable inner shaft and then be sucked in through an opening of the inner hollow shaft.
