Description

Be used for painful branch of academic or vocational study nerve pine art improvement needle sword

Technical Field

The utility model relates to the field of medical equipment, concretely relates to be used for painful branch of academic or vocational study nerve lysis art improvement needle sword.

Background

Certain diseases cause neuropathic pain, the most common clinical cause of post-herpetic neuralgia, usually after one to three months due to herpes zoster virus infection. Meanwhile, in the process of tissue repair caused by tissue damage, neurovascular grows in granulation tissue, and the growth is disordered and weaker and is more easily invaded by virus or inflammatory mediators. The virus gradually invades from the nerve root to the nerve endings along the damaged nerve. In this process, the nerve capsule is destroyed. In addition, the nerve trunk is exposed. In particular, nerve endings are more vulnerable. A large number of inflammatory mediators or factors can stimulate nerve endings to produce pain, which is intolerable, and even under the stimulation of a plurality of factors, central sensitization hyperalgesia pain is caused, and pain is amplified. Bringing great pain to the patients. Restlessness in sitting and lying can not lead to normal life and serious disorder of physiological function. Some patients may cause cardiovascular and cerebrovascular complications, and death has been reported. Except medicines, nerve block therapy, radio frequency therapy and trioxygen therapy are all the pathological characteristics of the disease, so the curative effect is often poor, in recent years, subcutaneous or intradermal nerve block, methylene blue and trioxygen are adopted in our hospital and simultaneously combined with needle knife subcutaneous nerve lysis therapy, the curative effect is obvious and is determined by patients, but at present, the needle knife is based on tissue adhesion, constriction, clamping pressure, circulatory disturbance, ischemic necrosis, exudation and inflammatory factor release increase caused by chronic tissue injury, and the vicious circle is formed. When treating such diseases, long, shoveling, cutting, longitudinal separation, prying and other manipulations are often adopted. To solve the tissue change caused by the above reasons, to relieve the disease and achieve the expected curative effect, but when treating neuropathic pain caused by herpes zoster. Because the shape of the needle knife is fixed and unchanged, when the nerve is loosened, the needle knife needs to be held, pried, scratched and shoveled at the front side, so that the skin is not damaged, the injury of subcutaneous fascia and tissues under the fascia is avoided, and the nerve can be loosened in place completely. The needle knife is characterized in that the needle knife is provided with a needle knife body, a needle knife body is arranged on the needle knife body, and a needle knife body is arranged on the needle knife body. While retaining the basic functionality of the needle-knife. Firstly, changing the width of the needle knife, and increasing the width by one time, two times, three times and four times respectively; secondly, the tool bit part A at the front end has an upright position (original position); B. respectively bending to the left, the front, the right and the front; C. respectively bent to the left and right. D. Respectively bent to the left rear and right rear. E. The cutter head is changed into an arc shape. Thirdly, a handle is added on the knife tail for convenient holding.

Although our primary improvement is not a handle, in a stressful surgical environment, the blade direction still needs to be changed continuously, the rotatable handle can well support the palm, and the finger pressure of the holding part is relieved to a certain degree, but the design of the handle is only applied to a few surgeries at present.
