Description

Disposable fascia injection needle sword

Technical Field

The utility model relates to the field of design and application of needle cutters, in particular to a disposable fascia injection needle cutter.

Background

The closed loosening operation is a treatment means integrating the basic theory of traditional Chinese medicine and the western medicine theory, is a common treatment means at present, and needs to be operated by using a needle knife made of metal materials when the closed loosening operation is carried out, and the needle knife is similar to a needle and a knife in shape, is a traditional Chinese medicine needle tool, has slightly different shapes and lengths, is generally about 10-15cm, and has different diameters of 0.4-1.2 mm. The existing needle knife mainly comprises a hand-held handle and a needle body, the needle body comprises a blade, the blade is sharp, and the blade can be utilized for loosening operation.

In clinical applications, conventional needle-knives have the following disadvantages when performing the loosening operation:

1. when the straight needle knife pierces the skin and inserts the needle, an included angle is formed between the needle body and tissues such as nerves, tendons and muscles, and when the tissues parallel to the skin are required to be longitudinally cut and peeled off, the hands of a surgeon are easy to collide with the skin in vitro, and especially the hands are more obvious when the hands are required to be closely inserted into the skin, so that the cutting and separation of fascia along the longitudinal tissues parallel to the plane of the skin are very unfavorable.

2. When the hand-held handle is used for needle insertion, the hand-held handle is generally held to exert force, the handle body is smooth, the needle handle is fixed in an unstable manner, and the needle point is difficult to move back and forth to separate from the target point after being punctured to the target point.

3. When the needle is loosened, various Chinese and western medicines are often required to be injected, so that the effects of anesthesia, anti-inflammation, blood circulation promoting, blood stasis removing and the like are achieved, a better clinical treatment effect is achieved, and the existing needle knife is required to be matched with an injector for use.

Chinese patent: an injection needle knife (CN 214761350U) disclosed in the patent document can realize the operation and use of loosening and injection by additionally arranging an injection tube part and arranging a liquid outlet on a needle body, and solves the defect that the existing needle knife cannot be used for loosening and injection at the same time.

The technical scheme is based on the structure of the existing needle knife, and the structure of the needle knife is further perfected and improved, so that the needle knife can effectively solve the technical defects, and better treatment operation and use are realized.
