DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Clinically, minimally invasive endoscopic techniques for the treatment of urinary stones have largely replaced traditional open surgery. Treatment of upper urinary tract stones through natural channels has become a mainstream surgical approach, recognized by both physicians and patients for its safety, effectiveness, and speed. During surgery, a flexible or rigid sheath is inserted and placed through natural channels such as the urethra, bladder, and ureter to the surgical site. A flexible or rigid ureteroscope is then inserted through the channel, and lithotripsy is performed using a lithotripsy device such as a holmium laser. Simultaneously, an irrigation solution is continuously infused through the flexible or rigid ureteroscope. This irrigation solution is then discharged through the sheath outlet to effectively control renal pelvic pressure, maintain a clear field of view, and simultaneously fragment and clear the stones. During this process, the discharged stones, soft tissue, and irrigation solution form a mixture. Medical personnel often undergo multiple, tedious and time-consuming steps, including filtration, sedimentation, and collection, to separate the stones from the mixture. This allows for stone sample extraction for component analysis and subsequent targeted prevention and treatment options for the patient.
[0024] Example 1:
[0025] Based on the technical defects of the existing technology, such as the inconvenience of stone sample removal and the easy contamination of samples and the hands of medical staff during the removal process, please refer to Figure 1-Figure 4The utility model provides a stone surgical collector, the whole removal process can be operated with one hand, the operation is simple and convenient, and it will not contaminate the sample and the hands of medical staff, which is safer and more reliable. It includes a liquid collecting bottle 1, a funnel 2 is threadedly connected to the bottle mouth of the liquid collecting bottle 1, and a collecting component 3 for separating stones from the liquid is placed on the inner side of the funnel 2. The outer side of the liquid collecting bottle 1 is provided with a mounting component 7 for fixing the whole. The liquid collecting bottle 1 is fixed on the operating table by using the mounting component 7, and the funnel 2 is connected to the liquid collecting bottle 1. Finally, the collecting component 3 is placed in the funnel 2, and the flushing liquid enters the funnel 2. Under the action of the collecting component 3, the stones are filtered out of the flushing liquid, and the flushing liquid is collected in the liquid collecting bottle 1. After the collection is completed, the stones can be taken out using the collecting component 3.
[0026] To facilitate the separation of stones from the irrigation solution, please refer to Figure 3 The collecting assembly 3 includes a collecting cylinder 31 placed on the inner side of the bottom of the funnel 2. A handle rod 33 is fixedly provided in the collecting cylinder 31 through a fixed rod 32. A movable rod 34 is movably connected inside the handle rod 33. A leakage net 35 is fixedly provided at the bottom of the movable rod 34. The leakage net 35 is attached to the bottom of the collecting cylinder 31. Under the action of the leakage net 35, the flushing liquid passes through the leakage net 35 and falls into the liquid collecting bottle 1, while the stones are retained on the leakage net 35. After the stone collection is completed, the collecting cylinder 31 can be removed by the handle rod 33, so that the stones can be taken out.
[0027] To facilitate the removal of stones from the collecting tube 31, a fixing plate 36 is fixed on the top of the handle rod 33, a pressing handle 37 is fixed on the top of the movable rod 34, and a spring 38 is fixed between the fixing plate 36 and the pressing handle 37 and is sleeved on the outside of the movable rod 34; when removing the stone, two fingers contact the fixing plate 36 and lift the collecting tube 31 through the handle rod 33, while the thumb presses the pressing handle 37 and drives the movable rod 34 to move downward, and the movable rod 34 drives the leakage net 35 to move downward. At this time, a gap is generated between the leakage net 35 and the bottom of the collecting tube 31, and the stone can fall through the gap.
[0028] In order to ensure that all the stones can fall off, the leakage net 35 is made into a cone-shaped structure; under the guiding effect of the cone-shaped structure, the stones are made to fall off more easily.
[0029] To ensure that the collecting assembly 3 can be smoothly placed in the funnel 2, an inner convex ring 21 for supporting the collecting cylinder 31 is fixed at the bottom of the funnel 2. The inner convex ring 21 provides support for the collecting cylinder 31 to ensure that the collecting assembly 3 is placed stably.
[0030] In order to prevent the drainage tube 6 from shaking and falling during the drainage process, an extension part 4 is provided on the outer wall of the funnel 2 near the top, and a Velcro 5 is fixed on the extension part 4, and the drainage tube 6 is adhered to the Velcro 5; the drainage tube 6 can be fixed on the funnel 2 using the Velcro 5.
[0031] Example 2:
[0032] When using, in order to facilitate the fixing of the liquid collecting bottle 1 and other components, please refer to Figure 1 On the basis of embodiment 1, the mounting assembly 7 includes a fixing ring 71 sleeved on the outer wall of the liquid collecting bottle 1, a support arm 72 is fixed on the outer wall of the fixing ring 71, and a fixing half ring 73 is fixed at one end of the support arm 72, and a movable half ring 74 is rotatably connected to the fixed half ring 73. A fixing bolt 75 is also threadedly connected to the fixed half ring 73, and one end of the fixing bolt 75 is threadedly connected to the threaded hole opened on the movable half ring 74; the fixed half ring 73 and the movable half ring 74 are fixed to the operating table, and the support arm 72 and the fixing ring 71 are used to support and fix the liquid collecting bottle 1, thereby ensuring the stability of the entire collector during use.
[0033] Through the above embodiment, it can be seen that: first, the funnel 2 is connected to the liquid collecting bottle 1, and finally the collecting component 3 is placed in the funnel 2, and then the fixed semi-ring 73 and the movable semi-ring 74 are fixed on the operating table, and the liquid collecting bottle 1 is supported and fixed by the support arm 72 and the fixed ring 71. During the collection process, the flushing liquid enters the funnel 2 through the drainage pipe 6. Under the action of the collecting component 3, the flushing liquid passes through the filter 35 and falls into the liquid collecting bottle 1, while the stones are trapped on the filter 35, filtering the stones out of the flushing liquid, and the flushing liquid is collected in the liquid collecting bottle 1. After the stone collection is completed, when taking out the stone, two fingers contact the fixed plate 36 and lift the collection tube 31 through the handle rod 33. At the same time, the thumb presses the pressure handle 37 and drives the movable rod 34 to move down. The movable rod 34 drives the filter net 35 to move down. At this time, a gap is generated between the filter net 35 and the bottom of the collection tube 31, and the stone can fall through the gap.
