Detailed Description

For the purpose of illustrating the concepts and objects of the utility model, the utility model is further described in connection with the drawings and detailed description that follow.

As shown in fig. 1 to 5, a needle-knife structure for cutting deep muscle fiber comprises a cannula 10 and a needle-knife 20, wherein the front end of the cannula 10 is an inclined surface 11, the front end of the inclined surface 11 is a needle tip 12, the needle-knife 20 is sleeved in the cannula 10 and can move back and forth along the cannula 10, and the surface of the inclined surface 11 is a blunt surface.

As shown in fig. 1 to 5, when the needle tip 12 is advanced into the muscle fiber of the surface layer, the inclined surface 11 of the cannula 10 is a blunt surface, the inclined surface 11 of the cannula 10 extrudes the muscle fiber of the surface layer, does not cut the muscle fiber of the surface layer, does not damage the muscle fiber of the surface layer, and after the muscle fiber of the surface layer is extruded, the needle knife 20 can be inserted into the deep muscle fiber along the cannula 10, and after the needle knife 20 is inserted into the deep muscle fiber, the needle knife 20 can cut the deep muscle fiber, thereby playing a role of protecting the muscle fiber of the surface layer.

As shown in fig. 1 to 5, the rear end of the sleeve 10 is provided with a clamping member 13, and the clamping member 13 is used for clamping the needle knife 20. When the needle knife 20 is not used, the clamping piece 13 clamps the needle knife 20, the needle knife 20 is relatively fixed with the sleeve 10, when the needle knife 20 is needed to be used, the needle tip 12 firstly enters the muscle fiber of the surface layer, the inclined surface 11 of the sleeve 10 extrudes the muscle fiber of the surface layer, the muscle fiber of the surface layer is not cut, after the muscle fiber of the surface layer is extruded, the clamping piece 13 is opened, the needle knife 20 can be inserted into the deep muscle fiber along the sleeve 10, and after the needle knife 20 is inserted into the deep muscle fiber, the needle knife 20 can cut the deep muscle fiber, so that the function of protecting the muscle fiber of the surface layer can be achieved.

As shown in fig. 1 to 5, the needle-knife 20 includes a knife head 21, a needle body 22 and a needle handle 23, the radius of the needle handle 23 is larger than that of the cannula 10, the radius of the needle body 22 is smaller than that of the cannula 10, and the knife head 21 is smaller than that of the cannula 10.

As shown in fig. 1 to 5, the cutter head 21 is a blade extending downward from the lower side of the cutter body. The needle knife 20 can be inserted into the sleeve 10 and can move up and down in the sleeve 10, after the surface layer of the muscle fibers are squeezed open, the clamping piece 13 is opened, the knife edge of the needle knife 20 can cut the deep layer of the muscle fibers, and the knife edge of the needle knife 20 cuts the muscle fibers on the same plane.

As shown in fig. 1 to 5, the clamp 13 includes an arc-shaped elastic clip body 131, a first handle portion 132 provided at one end of the elastic clip body 131, a second handle portion 133 provided at the other end of the elastic clip body 131, and an abutting portion 134 provided between the elastic clip body 131 and the second handle portion 133, the abutting portion 134 being located inside the elastic clip body 131.
