The technical scheme of the utility model is specifically described below with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a minimally invasive needle-loosening knife, which comprises a handle 1 and a needle knife head 2, wherein the needle knife head 2 is fixedly arranged at one end of the handle 1 in the axial direction (namely, the needle knife head 2 is fixedly arranged at one end of the handle 1 in the length direction), the needle knife head 2 comprises a fixing part 21 and a cutting part 22, the cutting part 22 is of a flat structure, and at least one side of the cutting part is provided with a blade 221.

Because the incision part 22 in the minimally invasive release needle knife is of a flat structure, pathological tissues can be conveniently incised and corresponding tissues can be released when the minimally invasive release needle knife is used; in addition, since the incision portion 22 has a flat structure during the operation, a single operation can perform the loosening treatment on the lesion tissue having a large area, thereby obtaining a good loosening effect.

Specifically, the handle 1 has a cylindrical or column-like structure as shown in fig. 1, and may be a flat bar-shaped structure with a certain thickness according to the habit of the user; the fixing portion 21 of the needle head 2 has a cylindrical structure at one end thereof adjacent to the handle 1, a truncated cone-like or conical structure at the other end thereof, and the cutout portion 22 is fixedly connected to the fixing portion 21.

The blade 221 is thinner as shown in fig. 3-4. In use, the thinner blade 221 can be conveniently penetrated subcutaneously to reach a lesion (e.g., tendon sheath, ligament, etc.), thereby performing an incision and release treatment on the area to be treated.

As an alternative embodiment, the free end of the cutout 22 is a sharp corner 222. The sharp angle 222 is the angle between the two tangential lines at the end of the cut-out 22, and as shown in fig. 2, the angle of the angle is always less than 90 degrees, and generally less than 60 degrees, for example, 45 degrees.

The incision portion 22 with sharp angle 222 provides for more convenient incision of the skin and insertion into the lesion assembly during use, thereby facilitating the loosening operation by the operator.

As an alternative embodiment, the blade 221 extends along the length of the incision portion 22 through a sharp angle 222 to an end of the incision portion 22 adjacent to the fixing portion 21, as shown in fig. 1.

As an alternative embodiment, the side of the blade 221 near the free end is curved.

The operator manipulates the arcuate blade 221 to provide a relatively short wrist distance of movement for cutting and insertion that is more comfortable and easier to apply than conventional straight blade 221.

As an alternative embodiment, the height of the middle of the cut-out 22 is greater than the height of both ends thereof. This structure can guarantee that above-mentioned arc structure is the bellied arc structure in middle part.

As an alternative embodiment, the fixing portion 21 and the cut-out portion 22 are of a unitary structure.

The integral structure can ensure the stability of the blade cutting part 22 and avoid the accidental falling of the cutting part 22 during operation.

As an alternative embodiment, the handle 1 is provided with a gripping area 11 on the side in the length direction close to the needle head 2.

The operator operates the incision portion 22 through the grip region 11 to perform the incision and release operations.

As an alternative embodiment, the grip region 11 is arranged recessed with respect to the surface of the handle 1.

This recessed structure can be used for gripping, is relatively easier to apply force than a cylindrical handle 1 portion, and is less prone to slipping.

In addition, at least two concave snap ring structures are arranged in the axial direction of the cylindrical handle 1, as shown in fig. 3-4.

For example, the needle knife can be used for loosening tenosynovial and ligament, and can be used for treating tenosynovitis, tennis elbow, carpal tunnel syndrome, mama hand (radius styloid tenosynovitis) and other diseases.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
