Description

Composite needle knife and needle tool

Technical Field

The utility model belongs to the technical field of the needle sword technique and specifically relates to a compound needle sword needling instrument.

Background

Small needle knife therapy is an occlusive, relaxing technique that is intermediate between surgical and non-surgical procedures. Is formed by combining an incisional surgery method and a needling method. The operation of the small needle knife therapy is characterized in that the treatment part is punctured into the deep part to the pathological change part to be easily cut and stripped to stimulate different operation processes so as to achieve the purposes of relieving pain and removing diseases. The indications are mainly soft tissue injury and osteoarthropathy.

In theory, the small needle knife medicine is guided by the theory of traditional Chinese medicine, combines with modern science, references the principle of surgical operation and innovates, forms the theory of closed operation, the new theory of etiology and pathology of chronic soft tissue injury, the etiology and theory of new hyperosteogeny and the like, has important guiding significance for clinical treatment, improves the curative effect, and is widely applied in the departments of internal, women, children, skin and the like because the small needle knife medicine has breakthrough in the aspect of the basic research of the etiology.

The small needle knife therapy has the advantages of simple operation of the treatment process and no limitation of any environment and condition. The incision is small during treatment, no suture is needed, the injury to human tissues is small, the infection is not easy to cause, the adverse reaction is avoided, the patient does not have obvious pain and fear feeling, the rest is not needed after the operation, the treatment time is short, the treatment course is short, and the patient can easily accept the medicine. Simplifying: the treatment is simple, no incision is caused, no bleeding is caused, and the pain of the patient is small. Then: the application is convenient, one needle knife and one pair of gloves can be used for operation after the skin is disinfected conventionally. The cost is low: low cost, low treatment cost and low treatment cost. Testing: has obvious physical therapy effect, takes effect once, cures most of the diseases three times, and cures some diseases once. Five major changes of medical realization of small needle knife: changing a large number of diseases from incurable to treatable; changing difficult treatment into quick healing; changing an open surgery to a closed surgery; changing complex treatment to simple treatment; the injury type and pain type treatment is changed into the non-injury and pain-free treatment.

The needle knife is widely applied in clinic by combining an injection technology, and a better curative effect is obtained, but in clinic, the simple injection, cutting and parallel loosening are performed by using different instruments in steps due to the limitation of the instruments, so that the treatment time and the probability of infection are increased, blood vessels can be damaged in the cutting process, the safety of the needle knife is influenced, the treatment risk is increased, and the pain of a patient is increased due to multiple operations.
