Patent number: 10299818Abstract: A device (1) for treatments of endoscopic resection/removal of tissues, includes: a handpiece apt to be held by an user; an external tubular element (3) having a proximal end, a distal end and a cutting aperture disposed at the distal end; an internal tubular element (4) apt to be pivotally housed in the external tubular element (3) and having a proximal end, a distal end and a cutting tip at its distal end. The device also includes guide elements (5) for rotating and/or oscillating the internal tubular element (4) with respect to the external tubular element (3). The guide elements (5) include an electric motor (19) and electric feeding element for the electric motor (19) and are contained completely inside the handpiece (2).Type: GrantFiled: June 14, 2010Date of Patent: May 28, 2019Assignee: FRII SAInventor: Raffaele Riva
