[0002] Urological endoscopy surgery is a minimally invasive surgical method, which has the advantages of small trauma and fast recovery. However, during the operation, the patient will produce urine. If it is not collected and processed in a timely and effective manner, it may pollute the surgical environment, increase the risk of infection, and may also affect the smooth progress of the operation and the postoperative recovery of the patient.

[0028] Please refer to Figure 1, is the overall three-dimensional structural schematic diagram of a urine collection device during urological endoscopy surgery of the present invention; the urine collection device of the present application can avoid cross-infection by adopting a disposable and detachable shunt ball 120, and adopts the negative pressure principle to actively aspirate urine, which speeds up the urine collection speed; through three series-connected collection components, it can be graded according to different volumes of urine generated during the operation. Collecting effectively responds to the uncertainty of urine production and avoids the risk of urine overflow; by controlling the air extraction volume inside the pressure bladder, the internal pressure of the corresponding collection bag can be gradually adjusted to achieve gradual urine aspiration; it realizes the technical effects of improved collection efficiency, reduced cross-infection risk, avoidance of urine overflow, improved liquid inlet smoothness, and meeting different surgical needs.

[0029] Example 1: As Figures 1 to 4 shown, a urine collection device during urological endoscopy surgery of the present application includes a collection barrel 100, a partition plate 101, a moving frame 110, a shunt ball 120, an output pipe 130, a sample cylinder 140, a collection part 200, and a liquid inlet pipe 201; There are three collection parts 200, which are evenly arranged along the circumference of the collection barrel 100 and fixed inside the collection barrel 100, corresponding to the liquid inlet pipes 201 one by one; The collection part 200 has a plurality of vertically arranged collection bags, and the plurality of collection bags are connected in series. They are all located below the corresponding liquid inlet pipe 201, and their outer parts are respectively covered with pressure bladders. A magnet 272 is fixed on the inner wall of each pressure bladder, and the pressure of the collection bag inside it is adjusted through magnetic attraction to achieve graded suction collection of urine.

[0030] The collection barrel 100 is a cylindrical structure and is made of visible transparent material, which is used to hold the collected urine; the partition plate 101 is a triangular structure and is fixed inside the collection barrel 100, which is used to separate the collection part 200; the moving frame 110 is fixed at the bottom of the collection barrel 100, which is used to move the entire collection device; there are three liquid inlet pipes 201, which are respectively fixed at the upper end of the collection barrel 100, which are used to transport urine from different human bodies; The shunt ball 120 is a disposable structure and has three shunt branch pipes 121 at its bottom. Each shunt branch pipe 121 is connected to the corresponding liquid inlet pipe 201 through a tie 122, which is used to transport urine to the collection part 200; there are three output pipes 130, which are respectively fixed at the bottom of the collection barrel 100, which are used to discharge the urine in the collection barrel 100; there are three sample cylinders 140, which are all fixed at the bottom of the collection barrel 100, which are used to store the collected urine samples.

[0031] The collection part 200 includes three sets of storage components, namely the first collection component 210, the second collection component 220, and the third collection component 230; The first collecting assembly 210 includes a first filter ball 211, a first collecting bag 212 and a first negative pressure ball 213. The first filter ball 211 is fixed below the liquid inlet pipe 201 and is in communication therewith. The first collecting bag 212 and the first negative pressure ball 213 are fixed below the first filter ball 211 in sequence. The second collecting assembly 220 includes a second filter ball 221, a second collecting bag 222 and a second negative pressure ball 223. The second collecting bag 222 and the second negative pressure ball 223 are fixed in sequence below the second filter ball 221. The third collecting assembly 230 includes a third filter ball 231, a third collecting bag 232 and a third negative pressure ball 233. The third collecting bag 232 and the third negative pressure ball 233 are fixed in sequence below the third filter ball 231. The first collection bag 212, the second collection bag 222 and the third collection bag 232 are all negative pressure bag structures, which are used to actively suck out urine through the negative pressure principle; The first filter ball 211 , the second filter ball 221 and the third filter ball 231 are all spherical in structure and are provided with a filter block 260 therein for filtering impurities in urine.

[0032] The diverter ball 120 is used to transport urine from different patients to different collection bags. The first negative pressure ball 213, the second negative pressure ball 223 and the third negative pressure ball 233 are all in a negative pressure state, which is used for urine buffering and maintaining normal flow and pressure balance during the infusion process.

[0033] Further, such as Figure 5 and Figure 6 As shown, the first collecting assembly 210 is fixed inside the collecting barrel 100 via a fixing frame 240 and is connected to the corresponding liquid inlet pipe 201 ; the second collecting assembly 220 and the third collecting assembly 230 are both fixed inside the collecting barrel 100 via a fixing frame 240 .

[0034] Between the first collection component 210 and the second collection component 220, and between the second collection component 220 and the third collection component 230, they are connected in series through a connecting pipe 250 and placed side by side, for achieving hierarchical collection. Through the three serially connected collection components, hierarchical collection can be carried out according to different volumes of urine generated during the operation, effectively coping with the uncertainty of urine generation, avoiding the risk of urine overflow. At the same time, hierarchical collection enables medical staff to more easily monitor the volume situation of each collection component and take timely measures (such as replacing the collection component that is about to overflow), avoiding the surgical environmental pollution and surgical interruption that may be caused by urine overflow, and can also increase or decrease the number of collection components according to actual needs to adapt to the needs of different surgeries or patients; moreover, when it is necessary to replace the collection component, since they are serially connected and relatively independent, they can be replaced individually without affecting the use of other components, thus reducing the risk of cross-infection that may be brought about by frequently replacing the entire collection device.

[0035] Further, as Figures 5 to 7 shown, a first pressure bladder 270, a second pressure bladder 280, and a third pressure bladder 290 are sequentially coated on the outer sides of the first collection bag 212, the second collection bag 222, and the third collection bag 232; the first pressure bladder 270, the second pressure bladder 280, and the third pressure bladder 290 are of a square plastic-sealed bag structure, with a hard material on the outer layer and a flexible material on the inner layer, and a plurality of magnets 272 are arranged on the inner side walls of the first pressure bladder 270, the second pressure bladder 280, and the third pressure bladder 290.

[0036] A plurality of iron sheets 271 that cooperate with the magnets 272 are fixed on the outer side walls of the first collection bag 212, the second collection bag 222, and the third collection bag 232, for adjusting the internal pressure of the corresponding collection bag through magnetic attraction and realizing the gradual suction of urine.

[0037] The interiors of the first pressure bladder 270, the second pressure bladder 280, and the third pressure bladder 290 are respectively connected to an air pump through different external pipes, for gradually adjusting the internal pressures of the corresponding first collection bag 212, second collection bag 222, and third collection bag 232 by controlling the air extraction amounts of the first pressure bladder 270, the second pressure bladder 280, and the third pressure bladder 290.

[0038] By controlling the amount of air extracted inside the first pressure bladder 270, the second pressure bladder 280, and the third pressure bladder 290, the flexible inner layer is deformed. Then, by controlling the deformation of the inner layer and cooperating with the magnetic attraction effect, the internal pressure of the internal collection bag is controlled. At the same time, it can also cooperate with the negative pressure ball corresponding to the front of the pipeline. By adjusting the pressure inside the bag, the pressure inside the overall pipeline is adjusted, and the urine flow rate into the negative pressure ball corresponding to the front of the pipeline is controlled. It can not only realize the gradual expansion of the first collection bag 212, the second collection bag 222, and the third collection bag 232, so as to gradually aspirate urine, but also realize the precise control of the expansion speed of the collection bag and the control of the urine flow collection speed, further enhancing the stability of the aspiration process. Compared with the traditional method relying on gravity or one-time aspiration, it can more effectively handle the collection of a large amount of urine and improve the aspiration efficiency. At the same time, the design of gradual aspiration makes the urine flow more smoothly during the collection process, avoiding problems such as too rapid expansion of the collection bag or unsmooth collection caused by a sudden influx of a large amount of urine.

[0039] When the embodiment of the present application is actually running, the steps are as follows: First, connect the shunt ball 120 to different liquid inlet pipes 201 through cable ties 122 to ensure tightness. Then, during the operation, connect the intraoperative urinary catheter to the input end of the shunt ball 120, adjust the input channel of the shunt ball 120 so that urine passes through the channel and is transported to the collection bag of the corresponding collection component through the corresponding shunt branch pipe 121. Medical staff monitor the capacity of the collection component by observing the collection bucket 100. When a certain collection component is close to overflowing, the component can be replaced separately without affecting the use of other components. Finally, when a urine sample needs to be collected, start the flow pipeline of the sample cylinder 140, so that the urine in the negative pressure ball flows into the sample cylinder 140 through the output pipe 130 to complete the sample collection.

[0040] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: The adoption of the disposable detachable shunt ball 120 can avoid the risk of cross-infection that may be brought by repeated use and improve the hygiene and safety during the operation. By adopting a negative pressure type collection bag, urine can be actively aspirated, greatly improving the collection efficiency compared with the traditional gravity flow collection method, especially in the case where the collection container needs to be quickly emptied. At the same time, compared with a fixed collection chamber, the collection bag is more flexible and can select different capacities according to actual needs to adapt to the urine collection requirements of different surgical situations. The design of the negative pressure ball makes the urine sample collection faster and more accurate. The design of the negative pressure bag structure and the negative pressure ball reduces the contact between urine and the external environment, reduces the risk of urine sample contamination, and ensures the purity of the sample and the accuracy of the test results. It realizes the technical effects of improving the collection efficiency, reducing the risk of cross-infection, avoiding urine overflow, improving the smoothness of liquid inlet, and being able to meet the different surgical requirements.

[0041] Embodiment 2: In order to make the urine suction process smoother, avoid pressure fluctuations or accidental inhalation of external air that interfere with the operation, and improve the flexibility and stability of the device, this application proposes the following technical solutions to address the above technical problems, specifically: like Figure 7 and Figure 8 As shown, the iron sheets 271 on both sides of the outside of the first collecting bag 212 , the second collecting bag 222 and the third collecting bag 232 are all arranged in an up-and-down staggered manner.

[0042] The magnets 272 on both sides of the inner walls of the pressure bladder 1 270 , the pressure bladder 2 280 , and the pressure bladder 3 290 are arranged asymmetrically, and the magnets 272 and the corresponding iron sheets 271 are on the same horizontal line.

[0043] During actual use of the embodiment of the present application, the pressure bladder three 290 is first evacuated so that the third collection bag 232 expands to perform the first-level suction of urine, and then the pressure bladder two 280 is suctioned. At this time, the second collection bag 222 expands to perform the second-level suction of urine, and finally the pressure bladder one 270 is suctioned. At this time, the first collection bag 212 expands to perform the third-level suction of urine; the gradual suction strategy can more effectively utilize the capacity of each collection bag, avoid the risk of urine overflow due to the excessive capacity of a single collection bag, and also improve the suction efficiency of the entire collection system.

[0044] The present application ensures a one-to-one correspondence between the magnet 272 and the iron sheet 271 through an asymmetric and staggered arrangement, thereby avoiding accidental contraction or deformation of the corresponding collection bag due to the magnet 272 being sucked into the wrong position during the suction process, so that urine can flow into the corresponding collection bag more smoothly during the suction process, avoiding poor urine flow or splashing due to changes in the shape of the collection bag; by precisely setting the corresponding positions of the magnet 272 and the iron sheet 271, external air can be prevented from being accidentally drawn into the corresponding collection bag during the suction process, and air entry can be prevented from contaminating the urine sample, thereby affecting subsequent test results; at the same time, the staggered expansion design of the corresponding collection bag can increase the expansion amount, thereby further improving the suction effect.

[0045] During the operation, if there is a sudden increase in urine production or the collection bag is about to overflow, medical staff can quickly adjust the capacity of the collection bag by adjusting the suction volume of the pressure bag, making emergency operations simpler and easier, and helping to ensure the smooth progress of the operation.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
