Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a urology stone flushing device and a use method thereof. Background Art

[0002] Kidney stones are a common disease of the urinary system. They occur more often in men than in women, mostly in young and middle-aged people, and there is no significant difference in the incidence between the left and right sides. 40% to 75% of patients with kidney stones have varying degrees of back pain. The stones are large but have little mobility, which manifests as soreness and discomfort in the waist, or dull pain or dull pain when physical activity increases. According to the announcement number: CN213249511U, a urology stone flushing device is disclosed, but the technical solution still has the following deficiencies in practical application: 1. After the above technical solution is completed, there is no corresponding collection device after the stone is flushed, so the crushed stones remain in the patient's urethra. If they cannot be discharged in time, they are easy to accumulate together to form stones, causing discomfort to the patient; 2. When flushing the stones, the cleaning solution is manually pushed to flush the stones. However, this method is not easy to adjust the water pressure of the cleaning solution output, which easily causes further discomfort to the patient when flushing the stones. 3. When inserting the flushing tube into the patient's urethra, if the curvature and flexibility of the flushing tube are not good, the flushing tube will cause friction with the patient's urethra, causing urethral damage to the patient, thereby aggravating the patient's pain.

Disassemble the separation box from the threaded cover, and then take out the stone collection net barrel to process the collected stones.

[0015] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0016] Beneficial effect: In the present invention, through the provided pressure regulating mechanism, after the joint is connected to the external cleaning liquid delivery mechanism, the joint can be driven to move laterally by operating the regulating component. At this time, under the transmission action of the connecting cover, the moving ring can be driven to move laterally in the supporting cover, so that the communicating area between the connecting cover and the regulating hole can be adjusted, so that the flow rate of the cleaning liquid flowing into the delivery cover can be adjusted, so the pressure of the cleaning liquid can be adjusted. Therefore, when flushing stones, the water pressure of the cleaning liquid can be conveniently adjusted, thereby reducing discomfort when flushing stones in the patient's urethra; In the present invention, through the separation mechanism, after the waste liquid collection mechanism is started, the cleaning liquid and the crushed stones in the urethra can be sucked into the outer hose, and then the cleaning liquid and the stones can be transported to the separation box through the installation box and the downpipe. At this time, the stone collection net barrel set can collect the crushed stones, and the cleaning liquid can be transported to the hose through the stone collection net barrel so that it can be transported to the waste liquid collection; In the present invention, the waste liquid collection mechanism is provided, and the suction pump can be started to make the hose have suction force, so that the waste liquid and stones can be sucked, and the filtered waste liquid can be transported to the waste liquid tank, so that the waste liquid can be sterilized and disinfected by the disinfection mechanism; In the present invention, through the provided disinfection mechanism, the disinfectant powder can be dispersedly placed in a plurality of placement plates, and the support bracket is placed in the isolation net barrel. After that, the isolation net barrel is placed in the supporting net tube. At this time, the supporting net tube is clamped and limited by the clamping assembly. After the waste liquid is pumped into the waste liquid tank, the dispersedly placed disinfectant powder can be dissolved in the waste liquid, thereby sterilizing and disinfecting the waste liquid. In addition, the disinfectant powder is distributed more dispersedly, so the disinfectant powder can be quickly dissolved in the waste liquid.

[0017] In the present invention, by providing a heating mechanism, the cleaning liquid flowing into the inner tube can be heated by the heating ring, and the cleaning liquid can be adjusted to an appropriate temperature, thereby improving the comfort of the patient. At the same time, maintaining the appropriate temperature of the cleaning liquid can reduce the stimulation of the cleaning liquid to the patient's urethral tissue and improve the treatment effect. In the present invention, by arranging a braided hose inside the outer hose, the outer hose can be flexibly bent and changed in direction according to the bending path and length of the patient's urethra during insertion into the patient's urethra, which can effectively reduce friction and damage during insertion of the outer hose, improve the comfort and safety of operation, and at the same time ensure the toughness of the outer hose, prevent the outer hose from bending and folding in the patient's urethra, thereby affecting the output of the cleaning solution and the flushing of stones, and further improve the comfort of the patient; The present invention can adjust the punching pressure of the cleaning liquid when flushing the stones in the patient's urethra, so as not to increase the discomfort of the patient during flushing, and can also timely suck out the crushed stones, thereby preventing the crushed stones from remaining in the patient's urethra.

[0024] The separation mechanism is connected to the threaded cover 16. The separation mechanism specifically includes a separation box 17 threadedly connected to the threaded cover 16, which is convenient for disassembly and cleaning. A first support ring 19 is fixedly installed in the separation box 17, and a stone collection net barrel 20 is set on the first support ring 19 to collect the crushed stones. A hose 18 is fixedly installed on the bottom inner wall of the separation box 17, and the bottom end of the hose 18 extends to the bottom of the separation box 17 and is connected to the waste liquid collection mechanism. After the waste liquid collection mechanism is started, the cleaning liquid and the crushed stones in the urethra can be sucked into the outer hose 2, and then the cleaning liquid and stones are transported to the separation box 17 through the installation box 1 and the downpipe 15. At this time, the stone collection net barrel 20 can collect the crushed stones, and the cleaning liquid flows into the hose 18 through the mesh of the stone collection net barrel 20 so as to be transported to the waste liquid collection mechanism.

[0025] When in use, the cleaning liquid is first transported to the joint 9 through the external cleaning liquid transport mechanism, and then passes through the connecting cover 8, the movable ring 7, and the inner tube 43 of the transport cover. At this time, the heating source 44 is started, so that the heating ring 45 sleeved on the outer periphery of the inner tube 43 heats the cleaning liquid flowing through the inner tube 43. When heated to a suitable temperature, the cleaning liquid is transported to the outer hose 2. By adjusting the adjusting screw 12 in the pressure regulating mechanism, the flow rate and pressure of the cleaning liquid can be adjusted to meet the needs of different patients. Then, the outer hose 2 is inserted into the patient's urethra. Under the action of the internal braided hose 3, the outer hose 2 will deform according to the curved path of the patient's urethra, so that the inserted outer hose 2 coincides with the patient's urethral path, and the waste liquid collection mechanism is started to suck the cleaning liquid and stones in the urethra into the outer hose 2, and then through the installation box 1, the downpipe 15 and the hose 18, the cleaning liquid and stones are transported to the separation box 17. In the separation box 17, the stones are collected by the stone collection net barrel 20, and the cleaning liquid flows into the waste liquid collection mechanism through the hose 18. Finally, the waste liquid in the waste liquid collection mechanism is disinfected and sterilized.

[0026] The waste liquid collection mechanism includes a cover plate 21 and a waste liquid tank 22.

The top of the mounting rod 41 is tightly clamped with the top inner wall of the clamping cover 36. In order to ensure the stable connection between the clamping cover 36 and the support network tube 35, a clamping rod 38 is slidably connected through the connecting frame 37. A clamping groove matching the clamping rod 38 is provided on the top of one side of the L-shaped frame 33. After the support network tube 35 is clamped on the support cover 34, the connecting frame 37 is rotated so that the clamping cover 36 and the support network tube 35 are tightly clamped. The card rod 38 is then released, and the second compression spring 39 in a stressed state will push the card rod 38 to move until one end of the card rod 38 is completely inserted into the card slot, thereby limiting the card cover 36 and ensuring that the card cover 36 is stably connected to the supporting network tube 35.

[0032] When in use, the suction pump 28 is first started to generate suction, and the waste liquid and stone fragments in the urethra are sucked into the waste liquid tank 22 through the hose 18. After the waste liquid falls into the waste liquid tank 22, it will contact the disinfectant powder dispersedly placed in multiple placement trays 42. These disinfectant powders will quickly dissolve in the waste liquid to sterilize and disinfect the waste liquid. Since the disinfectant powder is distributed more dispersedly, it can dissolve in the waste liquid more quickly, thereby improving the disinfection efficiency.

[0033] The present invention provides a method for using a urology stone flushing device, comprising the following steps: S1. First, let the patient lie on the operating table and use medical imaging equipment to illuminate the patient's urethra area to determine the location of the stone; S2, after the connector 9 is connected to the external cleaning liquid delivery mechanism, the outer hose 2 is inserted along the patient's urinary catheter, and with the assistance of the image display, the end of the outer hose 2 can be aligned with the area where the stone is located, and then the cleaning liquid can be delivered to the connection cover 8 along the connector 9, and then delivered to the inner tube 43 of the installation tube 1. At this time, the heating source 44 is started to make the heating ring 45 heat the cleaning liquid flowing through the inner tube 43 of the installation tube 1, and then the cleaning liquid can flow into the delivery cover 5 through the adjustment hole 6, and then can be output through the outer hose 2, so that the cleaning liquid can be used to flush the stone; S3. During the flushing process, the connecting plate 13 can be driven to move laterally by rotating the adjusting screw 12 under the threaded transmission action of the adjusting nut 14.
