A surgical device for use in minimally invasive laproscopic surgical procedures for percutaneously extracting 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 atleast dedicated bi-directional rotary movement of external rotary knob. The rotary knob is designed to have atleast 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.
