Description

A multifunctional water needle knife

technical field

The invention relates to the technical field of medical minimally invasive surgical instruments, in particular to a multifunctional water needle knife.

Background technique

Acupuncture knife is a new type of medical device that integrates acupuncture needles and scalpels. Acupuncture knife therapy is an original minimally invasive technique of traditional Chinese medicine in my country. Through several generations of clinical practice and exploration, acupotomy medical theory system has gradually formed. It plays an important role in the diagnosis and treatment of soft tissue pain and bone and joint diseases. Acupuncture medicine believes that "scar, adhesion, contracture, and blockage" are the four major pathological factors of chronic soft tissue pain and bone and joint diseases. According to the procedures, different surgical methods and knife methods are selected to incise scars, loosen adhesions, separate contractures, unblock blockages, restore the mechanical balance of soft tissues and bone joints, and exert clinical curative effects. For intra-articular lesions, needle-knife therapy can easily damage articular cartilage, synovium, blood vessels, and ligaments while incising scars, loosening adhesions, and separation contractures, resulting in congestion and swelling in the joints, and cannot effectively dredge blockages in the joints. , and even aggravate intra-articular blockage; for peripheral nerve entrapment and nerve root adhesion lesions, when using a needle knife to loosen adhesions, it is easy to cause iatrogenic nerve injury, secondary sensory and motor dysfunction; for myofascial lesions, usually When the flat blade-shaped needle knife is used to separate the contracture and unblock the blockage, the myofascia will be excessively damaged, and secondary adhesion and blockage will occur, which limits the clinical application of the needle knife in joint, nerve, and myofascial lesions. If a multifunctional water needle knife is designed, the tip can be in the shape of a round head, an oblique blade, or a sharp hook blade, which can bluntly release nerve adhesions, clear joint blockages, and separate myofascial contractures, that is, reduce joint, Nerves, blood vessels, and myofascial injuries can be washed, perfused, and anesthetized, which expands the scope of clinical use of acupotomy.

In the known technology, most of the small needle knives for clinical application are of solid structure. This kind of small needle knife organically combines the functions of the needle and the knife, and can pull away the adherent tissue, prevent dredging, and does not cut the skin and flesh. open. Since the small needle knife is operated in the affected area, the depth of needle insertion is not easy to control, which can easily cause accidental injury to the blood vessel during the operation, and the postoperative bleeding is unknown, resulting in secondary infection, and the medicine cannot pass through the small area. The needle-knife goes directly into the affected area. Therefore, the existing small needle knife has defects such as imperfect function, narrow treatment range, and low safety and reliability.

Contents of the invention

In view of the above-mentioned deficiencies in the current technology, the present invention provides a multi-functional water needle knife, which can unblock joint blockages, release nerve root adhesions or peripheral nerve entrapment, and cut myofascial contracture, including blunt release, clearing lesions, Dredging blockage, infusing drugs, local anesthesia, etc., reduce the pain of the patient, reduce the difficulty of operation, the operation is more convenient, the tissue damage is reduced, and the safety factor is high.

In order to achieve the above object, the present invention adopts the following technical scheme: a multifunctional water needle knife, including a needle knife with a blade and a needle knife with a sleeve, and the needle knife with a blade is used for the fixed-point positioning and separation of the water needle knife.
