Device for treatments of endoscopic resection/ removal of tissues

A device for treatments of endoscopic resection comprising:

• a handpiece adapted to be grasped by a user;
• an outer tubular element extending along a longitudinal axis (X-X) comprising a proximal end, a distal end and a cutting opening arranged at said distal end;
• an inner tubular element adapted to be rotatably accommodated in said outer tubular element;
• said inner tubular element extending along a longitudinal axis (X-X) and comprising a proximal end, a distal end and a cutting tip at its distal end;
• guiding means for rotating and/or oscillating said inner tubular element with respect to said outer tubular element;
• said guiding means comprising an i) electric motor with a motor output shaft with a distal end and ii) at least one power-supply battery pack for said electric motor contained inside said handpiece;
• a first clutch keyed on the inner tubular element substantially at the proximal end of the inner tubular element so that said inner tubular element can be removed from the handpiece;
• a motor output shaft;
• a second clutch keyed on the distal end of the motor output shaft and thereby axially slidable on the motor output shaft so that to axially slide on the motor output shaft;
• a motion transmitting member, interposed between said first clutch and said second clutch for decoupling the first clutch from said second clutch;
• said second clutch being shaped for coupling with said transmitting member;
• and said first clutch being shaped for removably coupling with said transmitting member;
• a supporting element fixedly-keyed through the fastening means to said motor output shaft, said supporting element being adapted to make said second clutch rotate;
• and
• at least one elastic element comprising a spring concentrically mounted on the motor output shaft and interposed between said second clutch and the supporting element to apply a thrust longitudinally onto second clutch.
