Embodiment 1
[0024] Embodiment 1: as figure 1 As shown, a compound medical knife is mainly used in spinal surgery or other orthopedic surgery. The composite medical tool of this embodiment includes a clamping part 1, a cutting part 2 and a grinding part 3, one end of the clamping part is connected to the driving mechanism, and the other end of the clamping part is connected to the end of the cutting part, so The other end of the cutting part is connected with the grinding part.
[0025] Wherein, the cutting portion is in the shape of a triangular prism, and three sides of the triangular prism are provided with cutting edges 21 along the axial direction, which are respectively a first cutting edge 21a, a second cutting edge 21b and a third cutting edge 21c.
[0026] Wherein, the three sides of the triangular prism can be directly processed into a cutting edge, so that the cutting edge and the triangular prism are integrated, and of course the cutting edge and the triangular prism can be se...
Embodiment 2
[0032] Embodiment 2: as figure 1 As shown, a compound medical knife is mainly used in spinal surgery or other orthopedic surgery. The composite medical tool of this embodiment includes a clamping part 1, a cutting part 2 and a grinding part 3, one end of the clamping part is connected to the driving mechanism, and the other end of the clamping part is connected to the end of the cutting part, so The other end of the cutting part is connected with the grinding part.
[0033] Wherein, the cutting portion is in the shape of a triangular prism, and three sides of the triangular prism are provided with cutting edges 21 along the axial direction, which are respectively a first cutting edge 21a, a second cutting edge 21b and a third cutting edge 21c. The triangular prism is a triangular prism formed by equilateral triangles, that is to say, the cross section of the triangular prism is an equilateral triangle.
[0034] Wherein, the three sides of the triangular prism can be directly...
Embodiment 3
[0043] Embodiment 3: as figure 1 As shown, a compound medical knife is mainly used in spinal surgery or other orthopedic surgery.
