摘要：
Disclosed is a cutter blade for tissue removal, comprising an outer cutter (3) being a front-to-back through tubular body in the axis direction and an inner cutter (2) movable relative to the outer cutter (3). There is at least one opening (33) on the tubular wall (36) of the outer cutter (3), and the edge of the opening (33) forms an outer cutting blade (34). The outer peripheral surface of the front of the inner cutter (2) has a convex edge (23) and a groove (24), and the convex edge (23) forms an inner cutting blade (26). The outer cutter (3) covers the front of the inner cutter (2), and the inner cutting blade (26) is exposed to the opening (33) and works with the outer cutting blade (34) for cutting. The cooperative cutting of the inner cutting blade (26) and the outer cutting blade (34) and the maneuverability of the inner cutter (2) relative to the outer cutter (3) can realize continuous cutting, effectively improve surgical results, and reduce the labor intensity of doctors, while avoiding cutting through skin or postoperative skin necrosis due to excessive removal of tissue, or poor surgical results due to too less removal of tissue, and ultimately make a surgical operation safer, faster, better and more reliable.L'invention concerne une lame d'élément de coupe pour le retrait de tissu, comprenant un élément de coupe externe (3), qui est un corps tubulaire traversant d'avant en arrière dans la direction d'axe, et un élément de coupe interne (2) mobile par rapport à l'élément de coupe externe (3). Il y a au moins une ouverture (33) sur la paroi tubulaire (36) de l'élément de coupe externe (3), et le bord de l'ouverture (33) forme une lame de coupe externe (34). La surface périphérique externe de l'avant de l'élément de coupe interne (2) a un bord convexe (23) et une rainure (24), et le bord convexe (23) forme une lame de coupe interne (26). L'élément de coupe externe (3) recouvre l'avant de l'élément de coupe interne (2), et la lame de coupe interne (26) est
