A surgical device for use in minimally invasive laproscopic surgical procedures for percutaneously mutilating and debulking the tissue. The device consists of an inner hollow elongated tube (2) with a sharp edge cutting member (21) located at its distal end. This tube is positioned concentrically within the lumen of an outer hollow elongated tube (1) which features a uniquely designed cutting member shield design (17) at distal end of outer elongated hollow tube (1). The cutting member shield will serve to act as an effective anti-mutilating element. The cutting member shield can be activated by at least dedicated bi-directional rotary movement of external rotary knob. The rotary knob is designed to have at least bi-directional rotary movement. The cutting member shield (17) can be activated by a dedicated movement of external rotary knob (3) at multiple positions. Rotating the knob on multiple sides enables the physician to have a convenient control over the exposure of the sharp edge cutting member during the tissue excision procedure. Such a distinctive feature of the device would aid the surgeon to have easy manipulation and limit accidental damage to the tissue by the sharp edge cutting member during the procedure.Linvention concerne un dispositif chirurgical destiné à être utilisé dans des interventions chirurgicales laparoscopiques non effractives pour la mutilation et réduction tumorale par voie percutanée du tissu.
