Problems solved by technology

[0002] The existing acupuncture-knife treatment method is to use the needle-knife to enter the superficial fascia layer to loosen the subcutaneous connective tissue, but some adhesions cannot be effectively separated, and the treatment is not thorough enough; Loosening and loosening. When encountering tissues with relatively strong toughness in the lesion, the needle tip or the hard metal head do not have the ability to cut and peel, and it is difficult to sweep, peel and loosen the medical treatment. The metal head is used for prying, while the needle tip or hard metal head is always exposed, which is easy to accidentally injure other soft tissues of the patient or bring pain to the patient

Embodiment 1

[0039] A needle knife of this embodiment, such as Figures 1 to 4 As shown, it includes a handle 1, a knife body 2, a soft sleeve 3 and a positioning and fixing mechanism 4; wherein: the fixed end of the knife body 2 is fixedly connected to the front end of the handle 1, and the free end of the knife body 2 is a knife edge 21; the positioning The fixing mechanism 4 sleeves the soft sleeve 3 on the blade body 2 in a positioning manner. In this embodiment, the positioning and fixing mechanism 4 is block-shaped. The front end face is provided with a vertical front positioning half slot 41, and the rear end face is provided with a rear vertical positioning half slot 43. The front positioning half slot 41 and the rear positioning The half slots 43 are connected to each other, and the lower end surface of the positioning and fixing mechanism 4 at the intersection of the two is horizontally provided with a locking groove 42; the tail of the soft sleeve 3 is provided with a sleeve fix...

Embodiment 2

[0049] A kind of needle knife of this embodiment and using method thereof, basic structure is the same as embodiment 1, difference and improvement are: as Figure 5-7 As shown, the positioning and fixing mechanism 4 is a plate-shaped structure with an "L" shape in cross section, a vertical front positioning half slot 41 is provided on the front end surface, and a locking protrusion 44 is provided on the bottom surface near the rear end surface; The tail of the casing 3 is provided with a casing fixing sleeve 31 with a cross-section in the shape of "dry". Position slot 312; the front positioning half-slot hole 41 is set in the casing clamping slot 312; the upper surface of the handle 1 near the front end is provided with a clamping blind hole 12 cooperating with the clamping protrusion 44 .

[0050] The basic steps of the method for using the needle knife in this embodiment are the same as those in Embodiment 1, the main difference being Step 3, specifically:

[0051] Step 1....

Embodiment 3

[0059] A needle knife and its use method in this embodiment, the basic structure is the same as that of Embodiment 1 or 2, the difference and improvement are: the soft sheath 3 is made of a material that can be absorbed by the skin, and there is no need for the subsequent step 5 to take out the tube step.

Abstract

The invention discloses a needle knife and a using method thereof, and belongs to the field of medical instruments. The needle knife comprises a handle, a knife body, a soft sleeve and a positioning and fixing mechanism, wherein the fixed end of the knife body is fixedly connected to the front end face of the handle, and the free end of the knife body is a knife edge; the positioning and fixing mechanism enables the soft sleeve to be sleeved on the knife body in a positioning mode, the cutting capacity of the knife edge is fully utilized, the position and the positioning relation between the soft sleeve and the knife edge are adjusted through the positioning and fixing mechanism, the soft sleeve shields the knife edge in the sweeping and scattering process, healthy tissue is guaranteed not to be accidentally damaged, the soft sleeve can be conveniently reserved for a long time after sweeping and scattering and stripping, adhesion parts are separated, so that a rapid and accurate medical effect is achieved; and the problems that in the prior art, various medical instruments only have the puncturing function, accidental injury is likely to happen due to the sweeping action and stripping, and medical treatment is not thorough are solved.

Description

technical field [0001] The invention relates to the field of medical equipment, more specifically to an acupotomy and its usage method.
