METHOD AND DEVICE FOR INTRACORPOREAL LIQUIDIZATION OF TISSUE AND/OR INTRACORPOREAL FRAGMENTATION OF CALCULI DURING ENDOSCOPIC SURGICAL PROCEDURES

摘要

Method and the tissue size-reducing device and / or other materials in an intracorporeal organ or an artificial bag intracorporeal. According to one embodiment, the device comprises a cutting tool elongate rotary cutting head or impaction mounted at the distal end of the tool and optionally with one or more suction ports formed and injection in the elongated body of the tool in the longitudinal direction thereof. According to a second embodiment, the device can comprise (a) a separate guide cannula, suction and injection can be introduced initially in the organ or the bag, and (b) a separate and elongate device section insertable into said cannula when it is put in place, and withdraw therefrom. A set of self-expanding protection may be placed at the distal end of the device according to either of the embodiments, and serves to form a protective cage around said rotary head. This protective cage is configured to prevent said head from damaging the body or the bag surrounding it. Is also provided an artificial bag which can be introduced into a body cavity through a natural opening or small incision so that then serve as a container for tissues, organs, tumors, and other calculations materials to be processed by the device and removed from the body.
