Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the first embodiment, as shown in fig. 1, the tool comprises a tool holder 1, a blade body 2 is fixedly mounted at the bottom of the tool holder 1, contact arc-shaped openings 5 are formed in the left upper sides of the front end and the rear end of the blade body 2, a cutting edge 3 is polished at the bottom of the blade body 2, and a dial gauge 4 is engraved on the surface of the front end of the blade body 2 above the cutting edge 3.

In particular, the cutter can straighten, slice and thin the costal cartilage, and the costal cartilage can be accurately cut into straight sheets no matter the costal cartilage is cut by direct pressing or sliding, thereby being convenient for operators with lower level to operate and use,

the success rate is improved, the projections on the surface of the costal cartilage are cut and removed by horizontally pushing and sliding by adjusting the angle of the cutter, the edges of the costal cartilage pieces can be thinned by downwards pushing obliquely, and the qualification rate of the costal cartilage carving is further improved.

Wherein, the single side of the cutting edge of the blade 3 is an inclined plane; the inclined plane blade is convenient for straightening, slicing and thinning.

Wherein, the outer surface of the knife handle 1 is provided with concave-convex lines; the friction force is improved through the concave-convex lines on the surface of the knife handle 1.

Wherein, the contact arc-shaped opening 5 is a right hand tail finger contact point; the handle 1 is held by the right hand, and the tail finger is contacted with the contact arc-shaped opening 5 at the position of the blade body 2, so that the blade body 2 is convenient for an operator to operate.

Wherein the knife handle 1 is in an elliptic strip shape as a whole; the handle 1 is an oval strip shape to facilitate holding by the operator.

In the second embodiment, as shown in fig. 6, the shank 1 is a polygonal elongated shape as a whole, and the rest is the same as that of the first embodiment.
