Problems solved by technology

Because the bones and joints of the human body all have arc-shaped structures, the soft tissues starting and ending at the bones and joints are not on the same plane. Some start from the concave surface of the bone joint, and some start from the convex surface of the bone joint. Type acupotomies cannot accurately loosen the adhesions, scars, and contractures of the soft tissues around these bone joints, so the curative effect is not good. Since the existing straight acupotomy cannot enter the joints, it cannot treat bone ankylosis of the bone joints

Embodiment Construction

[0017] This embodiment is used to explain the claims of the present invention, and the protection scope of the present invention is not limited to the structures described in the following embodiments.

[0018] As shown in Figure 1, the shape of the handle 1 is designed in imitation of the shape of a human body's fist. The handle 1 is connected with the straight knife rod 2, and the end of the straight knife rod 2 is connected with the cutter head rod 3. The end is a blade 4 .

[0019] As shown in Figure 2, there are four arc angles between the cutter head rod 3 and the straight cutter rod 2: a-10°, b-30°, c-60° and d-90°. Of course, it can also be designed as other angles.

[0020] As shown in Figure 3-1, the blade is a straight blade; as shown in Figure 3-2, the blade is an arc blade.

[0021] As shown in Figure 4, the projection of the cutter head rod on a plane perpendicular to the axis of the straight cutter rod is wedge-shaped, that is, trapezoidal, that is, the shape...

Abstract

An arc needle knife is disclosed in the present invention, it comprises a handle connecting with a straight knife rod, the end of the straight knife rod connecting with a knife head rod, the knife head rod arc connecting with the straight knife rod, an arc angle is 5 degree to 90 degree, the end of the knife head rod is knife edge. The needle knife handle designed by the present invention avoids neurovascular injury caused by knife edge line abnormal resulting in the needle knife handle from its design, firstly initiating bone joint bony rigidity closing operation release. The present invention is breakthrough existing needle knife using range, suitable for chronic soft tissue injury, hyperosteogeny and bone joint bony rigidity closing operation release.

Description

technical field [0001] The invention belongs to surgical medical equipment, and in particular relates to an arc-shaped needle knife used for closed surgical release for chronic soft tissue injury, hyperosteogeny, and ankylosis of bones and joints. Background technique [0002] In the past, it was not known that the lesions of chronic soft tissue injuries were caused by adhesions, scars, and contractures of the soft tissues at the starting and ending points around the bone joints, and it was not recognized that bone hyperplasia and joint bony ankylosis were the result of chronic soft tissue injuries. Therefore, in the existing technology, the closed surgical instrument for treating chronic soft tissue injury and bone hyperplasia is mainly a small needle knife, but there is no closed surgical instrument for bone and joint ankylosis. The existing small needle knives (diameter less than 3 mm) are used for soft tissue separation and acupoint stimulation, and the existing needle k...
