Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a special operating trolley for joint flushing treatment, in particular to a special operating trolley for joint flushing treatment. Background Art

[0002] Rheumatic diseases are a group of extremely common clinical syndromes with joint pain and fear of cold as the main symptoms. Rheumatism is the abbreviation of rheumatic diseases, which generally refers to a large group of diseases that affect bones, joints, muscles and surrounding soft tissues such as bursae, tendons, fascia, blood vessels, nerves, etc.

[0003] Inflammatory exudation within the joints or between soft tissues is the direct cause of local swelling and pain in rheumatic diseases. In particular, the inflammatory factors, immune complexes and enzymes contained in the inflammatory synovial fluid within the joints are the main causes of local immune reactions in the joints. If the inflammatory synovial fluid can be cleared in time, it will help to quickly eliminate local and systemic symptoms and restore the body's functions as soon as possible.

[0004] Among the existing technologies, the following are dedicated to needle innovation: CN201320859276.6 "A joint cavity flushing needle", which includes a flushing needle and a flushing needle core. The flushing needle core is placed in the flushing needle. The flushing needle includes a needle tube, a needle and a needle handle. The front end of the needle is provided with a small horseshoe surface outlet. The angle between the needle and the needle tube is β, β is greater than 90 degrees and less than 180 degrees. The end of the needle tube close to the needle is provided with a main outlet. The main outlet and the small horseshoe surface outlet are located on both sides of the axis of the needle tube. The flushing needle core is provided with a head that matches the shape and size of the small horseshoe surface outlet. The utility model changes the existing single-needle injection method. The unique horseshoe surface needle allows the needle to enter the skin tissue, which is both quick and non-invasive and will not cause tissue bleeding. During use, large debris or fragments in the joint fluid can be drawn out. The speed and effect of flushing the joint cavity are greatly improved, and the pain for patients is greatly reduced. The operation is simple and convenient.

[0005] There is also CN201510855023.5 "Improved Knee Joint Irrigation Needle", which includes a needle sleeve and a solid needle inserted into the needle sleeve, the needle sleeve includes a connecting sleeve and a needle core sleeve, the connecting sleeve is used to connect a 20ml syringe, and two elliptical needle eyes are provided at the front end of the needle core sleeve, the two needle eyes are arranged up and down, and staggered front and back; the solid needle includes a metal needle body and a handle, the metal needle body is sleeved in the needle core sleeve, and the handle is sleeved in the connecting sleeve; the present invention has a simple structure and a reasonable design, which solves the shortcomings of difficult puncture due to thickening of the cyst wall and incomplete flushing due to small needle eyes and large condylar granules.

[0006] Those committed to device innovation include: CN201710596169.1 "A joint irrigator", including: a liquid extraction needle, a liquid inlet tube, a liquid inlet tube one-way valve, a flushing tube, a flushing needle, a liquid discharge tube, a liquid discharge tube one-way valve, and a waste liquid collection bag. The flushing liquid in the flushing liquid bottle is output through the liquid inlet tube, and the peristaltic pump transports the flushing device to the flushing needle through the peristaltic flushing tube to flush the surgical wound or joint cavity; the flushed waste liquid is transported to the liquid discharge tube through the peristaltic flushing tube, and the waste liquid collection bag collects the waste liquid through the liquid discharge tube. The liquid inlet tube one-way valve and the liquid discharge tube one-way valve play a role in one-way liquid transportation. Its beneficial effects are: small surgical opening, simple structure, low flushing cost; automatic flushing technology is used, which can be quantitative, constant pressure, safe and fast.

[0007] There is also CN201821041541.9 "A water-muscle needle rheumatism treatment system", which is composed of an injection system (1), an injection handle (3), an injection needle (5) and a negative pressure system (12); wherein the injection system (1) is connected to the injection handle (3) via a pipeline (13); the injection handle (3) is connected to the needle seat connector (9) by a double-channel connector (7), a two-way conversion head (10), wherein the double-channel connector (7) is provided with a guide hole (8), and the two-way conversion head (10) is provided with a fork (11); the needle seat (4) is connected to the injection needle (5) and the needle seat connector (9), wherein one end of the injection needle (5) is provided with an injection hole (6); the injection handle (3) is connected to the negative pressure system (12) via a pipeline (13) and a fluid accumulation container (2). Its purpose is to irrigate the inflammatory fluid in the joint and tissue through the water-muscle needle, loosen the adhesion tissue, and dredge the blocked meridians.

[0008] In particular, CN201610186236.8 "A water tendon needle treatment system" discloses a water tendon needle treatment system for irrigating joints and soft tissues, in which an infusion liquid container, a tissue fluid collection container and a joint irrigating needle form a channel. When in use, the joint irrigating needle is delivered to the affected area, and the affected area is irrigated by a pump body provided in the infusion liquid container, and then the waste liquid is sucked out of the body by a negative pressure suction pump provided in the tissue fluid collection container. The irrigation and suction are controlled by a handle controller and / or a foot controller to remove accumulated fluid and turbidity, dredge meridians, and effectively and quickly perform joint and soft tissue irrigating treatment. However, in the joint irrigating needle treatment system, the joint irrigating needle needs to be provided with an inlet 43 and an outlet 45 at the needle tail, and valves are also provided at the inlet 43 and the outlet 45, respectively. The needle tail 44 also needs to be sealed with a closer 46. The joint irrigating needle system has at least the following problems: 1. Joint irrigating 1. The inlet and outlet on both sides of the needle tail are prone to interference and affect the strength, so valves are set at the inlet and outlet respectively; 2. The joint flushing needle has a high production cost, and it is connected to the infusion pipeline or syringe for flushing, and to the negative pressure device or syringe for absorbing water. The actual operation process requires repeated replacement of external tools, which is quite cumbersome. The overall disassembly and assembly of the system is very inconvenient, which is not conducive to cleaning and disinfection. When the tools are replaced, the waste liquid flows out and easily contaminates the treatment site; 3. During clinical operation, it is very inconvenient to take the joint flushing needle, and the needle core is not easy to remove, so the occluder needs to be removed; 4. Since the joint flushing needle is not fixed by a special fixing device, the joint flushing needle is prone to shaking under the action of water pressure, which is difficult to control during actual operation, affecting the accuracy of the operation. At the same time, there is also a risk of water leakage, which makes the operation inconvenient and slows down the progress of the operation.

[0009] At the same time, in the prior art, a joint flushing needle treatment system in the form of an operating trolley has not yet been found.
