Background

In clinical practice, the doctor generally uses 11 blade and 15 blade when cutting nail operation, and these two kinds of model blades all include two side arriss and two blades, and one of them blade is for being located the side edge of a side arris, and another blade is for being located the knife tip blade of knife tip. When the doctor uses these two kinds of model blades to cut the nail, handheld blade accomplishes ungual cutting through the knife tip blade, because the knife tip blade is comparatively sharp, and the nail is harder and more smooth, and the cutting power is wayward, very easily cuts into thick degree of depth during the operation, cuts and reach patient's nail bed, brings the unnecessary damage for the patient.

Disclosure of Invention

The invention is provided for solving the problems in the prior art, and aims to provide a nail cutting tool which can accurately cut the nail and avoid cutting the nail bed of a patient.

In order to achieve the purpose, the invention provides a nail cutting tool, which comprises a blade and a blade shell, wherein the blade comprises a blade tip cutting edge and a side cutting edge, the nail cutting tool also comprises the blade shell for mounting the blade, the first end of the blade shell is provided with a blade inlet, the blade inlet is used for placing the blade into the blade shell, the inside of the blade shell is a containing cavity for fixedly mounting the blade, the end surface of the second end of the blade shell is provided with a blade edge hole, the blade edge hole is used for penetrating the blade tip cutting edge of the blade, and the height of the blade tip cutting edge extending out of the blade edge hole is the thickness of a cut nail.

Furthermore, the first end of the cutter shell is provided with a first fastener mounting hole and a second fastener mounting hole along the length direction of the cutter shell, and the first fastener mounting hole and the second fastener mounting hole are respectively used for mounting fasteners so that one end of each fastener is abutted to one side end, opposite to the cutter point cutting edge, of the corresponding blade.

Further, the case second end side includes a first sidewall having an inner surface corresponding to the insert side edge.

Further, the utility model also comprises a guiding device, wherein the guiding device comprises a connecting shaft, a first mounting rack and a second mounting rack which are arranged symmetrically along the blade, wherein,

the first mounting frame comprises a first base, a first support and a first guide piece, the first base is arranged on the operating table surface, one end of the first support is connected with the first base, and the other end of the first support is connected with the first guide piece;

the second mounting frame comprises a second base, a second support and a second guide piece, the second base is arranged on the operating table surface, one end of the second support is connected with the second base, and the other end of the second support is connected with the second guide piece;
