Description

Technical Field

[0001] The invention relates to the field of needle knives, and in particular to a visualized hydraulic separation and loosening integrated needle knives. Background Art

[0002] Acupuncture has significant advantages in treating common orthopedic diseases, stenosing tenosynovitis and carpal tunnel syndrome. Stenosing tenosynovitis is an aseptic inflammation and belongs to the category of "arthritis". It is commonly known as trigger finger and snapping finger. It is common in manual laborers, mostly women. Western medicine believes that the cause of this disease is that after the tendon is excessively rubbed or repeatedly injured in the tendon sheath for a long time, the synovial membrane becomes edematous, and there are inflammatory changes such as increased exudation and thickening, which cause thickening, adhesion or stenosis of the tendon sheath wall. The main clinical symptoms are local movement disorders, local tenderness and nodules, and snapping may occur in severe cases. The flexion and extension of the affected finger are limited. The treatment of this disease includes Chinese medicine massage, external application of drugs, local blockade of Western medicine, small needle knife, surgical cutting, etc., all of which have different therapeutic effects, but there are also certain shortcomings.

[0003] Carpal tunnel syndrome is a type of disease in which the median nerve is compressed due to increased pressure in the carpal tunnel. It is also the disease most commonly treated surgically by hand surgeons. There are many non-surgical treatments for carpal tunnel syndrome, including acupuncture, external application of Chinese medicine, local blockade, brace immobilization and corticosteroid injection, but the efficacy is not satisfactory.

[0004] There are problems in the acupuncture knife treatment of these two diseases, especially in the treatment equipment. For example, when using a small acupuncture knife to treat flexor digitorum stenosing tenosynovitis and carpal tunnel syndrome, local anesthetic injection must be performed first. The drug injection layer is not clear under blind vision, and the injection is naturally not ideal, which increases the patient's pain. At the same time, for conventional acupuncture knife instruments, the operator's general needle insertion method is to insert the needle vertically into the skin at the lesion point. The treatment point is relatively limited, and it is often difficult to completely loosen the lesion site, so the treatment insertion points have to be increased, and even unnecessary damage to the patient is caused, in order to finally achieve the purpose of complete loosening.

[0005] However, the patent application with announcement number CN117562626A proposed in the prior art has scales marked on each part of the needle body to facilitate observation of the needle insertion depth. At the same time, the interior of the needle body is a flat hollow tube to facilitate injection of drugs. The needle tip can be a "flat-blade hollow tube type" or a "shaped-blade hollow tube type". Therefore, when injecting drugs, it not only has the effect of hydraulic separation, but also can achieve an immediate loosening effect. The hydraulic separation separates the diseased tissue from the normal tissue, and the needle tip can loosen the diseased tissue more conveniently and safely.

[0006] The surface of the needle is engraved with a detection thread surface, which makes its ultrasound imaging clearer, facilitates exploration and positioning under closed and blind surgery, and more accurately locates the lesion. It also enables the surgeon to accurately judge the needle insertion situation to avoid puncturing other tissues, thereby reducing the difficulty of medical staff's work and reducing surgical risks.

[0007] The needle handle and the needle body are at 135 degrees. Firstly, it is convenient for the operator to hold the needle. Secondly, when the operator pinches the needle handle to insert the needle, the needle body can be parallel to the skin and the lesion tissue. Under the guidance of ultrasound, it can not only achieve back and forth loosening at the lesion level, but also achieve fan-shaped loosening, ultimately completely loosening the lesion tissue.

[0008] The needle body has a threaded connector at the rear end, which is convenient for fixing the injection connecting tube or syringe to prevent the injection pressure from being too high and causing the drug to pop out of the interface. The interface is connected to the injection connecting tube for the convenience of the operator to position the assistant when administering the drug. When the operator observes the drug entering the lesion under ultrasound guidance, it is convenient to adjust the direction of the needle to fully inject the drug into the lesion, thereby achieving the effect of hydraulic separation and making it easier to loosen the lesion. When connecting the syringe, when treating other bone and joint diseases, the syringe connected to the entire operating instrument can also be inserted vertically, which is convenient for the integration of injection and loosening.

[0009] However, in order to prevent the pain of secondary operation on the patient, the current device has a connection port on one side for the injection of medical injection solution. This method requires the syringe to be connected to the needle knife, but the needle knife may shake during the connection process, which may easily cause damage to the patient's internal tissues.

[0010] Therefore, it is necessary to provide a visual hydraulic separation and release integrated needle knife to solve the above technical problems. Summary of the invention
