The stripping blade is not sharp, and the stripping blade is required to be attached to the tendon in the process that the extractor body slides into the human body along the tendon, so as to strip the tissues around the tendon;
the transition edge is arranged in a transition area of the stripping edge and the cutting edge, the transition edge is not sharp, the cutting edge is higher than the stripping edge and is also higher than or equal to the cutting edge, and the transition edge is used for preventing the tendon from accidentally sliding onto the cutting edge according to the cutting edge when the extractor body slides on the tendon;
the cutting edge is sharp and is used for cutting off the tendon, and when the tendon needs to be cut off, the tendon extractor is rotated along the circumferential direction to enable the cutting edge to face the tendon.
In conclusion, the scheme provides a semi-sharp cutting edge structure, so that the unsharpness stripping edge is attached to the tendon when the tendon slides; when the tendon needs to be cut, the tendon extractor is rotated to make the cutting blade cut against the tendon.
Optionally, the height of the transition edge is equal to the height of the cutting edge.
Optionally, an inner bore is formed in the body.
Optionally, the inner hole is circular.
Optionally, the body is provided with an axially extending groove.
Optionally, the groove is a straight groove or an inclined groove.
Optionally, the rod part is provided with an embedded groove, and the body part is inserted and fixed in the embedded groove.
Optionally, the insertion part and the body part are integrally formed.
Optionally, the cutting edge is integrally formed with the body.
Optionally, the rod portion is provided with a scale mark.
Optionally, the number of the stripping edges is not less than 2.
Optionally, the number of the cutting edges is not less than 2.
The utility model has the advantages that: provides a semi-sharp cutting edge structure, which leads the unsharpened stripping edge to be attached to the tendon when sliding; when the tendon needs to be cut, the tendon extractor is rotated to make the cutting blade cut against the tendon.
Description of the drawings:
FIG. 1 is a schematic diagram of a tendon extractor;
fig. 2 is an enlarged schematic diagram at a in fig. 1.
The figures are numbered: 1. the cutting tool comprises a rod part, 2, a handle, 10, a body part, 101, an inner hole, 11, a cutting edge, 111, a stripping edge, 112, a transition edge, 113, a cutting edge, 15 and a chute.
The specific implementation mode is as follows:
the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a tendon extractor comprises a rod part 1 and a handle 2, wherein the handle 2 is fixed on the rod part 1, the tendon extractor further comprises a body part 10 and a cutting edge 11, the cutting edge 11 is fixed with the body part 10, a peeling edge 111, a transition edge 112 and a cutting edge 113 are arranged on the cutting edge 11, the cutting edge 113 is sharper than the transition edge 112 and the peeling edge 111, and the height of the transition edge 112 is greater than the height of the peeling edge 111 and the height of the cutting edge 113.
The peeling edge 111 is not sharp, and the peeling edge 111 is adhered to the tendon to peel off the tissues around the tendon in the process that the body of the extractor slides into the human body along the tendon;
the transition edge 112 is arranged in the transition area of the peeling edge 111 and the cutting edge 113, the transition edge 112 is not sharp, the cutting edge 11 is higher than the peeling edge 111 and is higher than the cutting edge 113 or is as high as the cutting edge 113, and the transition edge 112 is used for preventing the tendon from accidentally sliding onto the cutting edge 113 according to the cutting edge 11 when the extractor body slides on the tendon;
the cutting blade 113 is sharp for cutting the tendon, and when it is necessary to cut the tendon, the tendon remover is rotated in the circumferential direction so that the cutting blade 113 faces the tendon.
In conclusion, the scheme provides a semi-sharp cutting edge 11 structure, so that the unsharpened stripping edge 111 is attached to the tendon when sliding; when the tendon needs to be cut, the tendon extractor is rotated to cut the tendon with the cutting blade 113 facing the tendon.
As shown in fig. 1 and 2, the height of the transition edge 112 is equal to the height of the cutting edge 113.
