[0002] Kidney stones are a common urological condition. With the advancement of medical equipment, the mainstream treatment for kidney stones has gradually shifted from traditional surgery to minimally invasive surgery. During minimally invasive kidney stone surgery, renal pelvic irrigation is often performed to maintain a clear surgical field and flush out lithotripsy. However, current standard procedures can still increase intrarenal pelvic pressure, leading to renal reflux and absorption of perfusate containing bacteria and endotoxins, causing postoperative fever and sepsis. Therefore, continuous and effective monitoring of intrarenal pressure and controlling it at a certain level can reduce the incidence of renal reflux and improve the safety of minimally invasive kidney stone surgery.

[0003] Some of the existing perfusions in lithotripsy rely on liquid gravity perfusion or manual injection perfusion, which may cause overpressure during the operation, resulting in damage to the kidneys and ureters or postoperative complications.

[0036] Figure 1An embodiment of the perfusion system is shown in FIG. Figure 1 The present invention provides a perfusion system 100, which includes a first pressure sensor 1, a second pressure sensor 2, an endoscope 3, a perfusion device 4, and a control host 5. The perfusion system 100 can be used for, but is not limited to, kidney stone treatment, and can also be used for other treatments, without specific limitations herein. However, for ease of explanation, the present invention uses the perfusion system 100 for kidney stone treatment as an example.

[0037] The endoscope 3 has a tip end, which is equipped with the first pressure sensor 1. The first pressure sensor 1 is configured to measure the pressure of the site to be perfused. When the perfusion system 100 is used in the treatment of kidney stones, the tip end of the endoscope 3 is inserted into the kidney. The first pressure sensor 1 can directly measure the pressure within the kidney, accurately and directly monitoring the pressure in the kidney in real time, thereby improving the safety of the patient's treatment process.

[0038] The perfusion device 4 is connected to the endoscope 3 via a perfusion line 42 and is used to perfuse liquid into the area to be perfused. The perfusion device 4 includes a perfusion liquid source 41, a perfusion line 42, a perfusion pump head 43, and a first drive motor 44. The perfusion liquid source 41 is used to provide perfusion liquid. The perfusion liquid source 41 is typically a perfusion liquid bag filled with perfusion liquid, but other containers may also be used in other embodiments. One end of the perfusion line 42 is connected to the perfusion liquid source 41, and the other end is connected to the perfusion pump head 43. The perfusion pump head 43 extends into the endoscope 3 and is used to perfuse liquid into the area to be perfused. The first drive motor 44 is drivably connected to the perfusion pump head 43 and is electrically connected to the control host 5. When the perfusion system 100 is used in the treatment of kidney stones and perfusion of liquid into the kidney is required, the control host 5 can control the first drive motor 44 to drive the perfusion pump head 43 to perfuse liquid into the kidney. Compared with the perfusion in lithotripsy treatment in the prior art, some of which rely on liquid gravity perfusion or hand-push injection perfusion, which may cause overpressure during the operation, damage to the kidneys and ureters or postoperative complications; the utility model can accurately control the perfusion volume, avoiding the occurrence of the above situation.

[0039] It should be noted that the first pressure sensor 1 can directly monitor the pressure in the kidney, and can also judge whether the perfusion pressure in lithotripsy treatment is reasonable based on the pressure value detected by the first pressure sensor 1. When the pressure is too high, the perfusion flow rate is reduced; when the pressure is too low, the perfusion flow rate is increased, thereby improving the convenience of equipment operation.

[0040] The control host 5 is electrically connected to the perfusion device 4, the first pressure sensor 1, and the second pressure sensor 2 to control perfusion by the perfusion device 4. The control motor can obtain the pressure values ​​of the first pressure sensor 1 and the second pressure sensor 2. The second pressure sensor 2 is provided on the control host 5, that is, the second pressure sensor 2 is provided on the host end. The second pressure sensor 2 is configured to measure the pressure within the perfusion line 42. By providing the first pressure sensor 1 and the second pressure sensor 2 at the same time, the values ​​measured by the first pressure sensor 1 and the second pressure sensor 2 can be compared to determine whether the first pressure sensor 1 and the second pressure sensor 2 have failed. Because the second pressure sensor 2 does not directly measure the pressure within the kidney, there will be a certain deviation from the pressure value measured by the first pressure sensor 1. When the deviation is within the allowable range, the first pressure sensor 1 and the second pressure sensor 2 are considered to be normal. When the deviation is not within the allowable range, it is considered that at least one of the first pressure sensor 1 and the second pressure sensor 2 has failed, thereby reducing the safety risk caused by the failure of a single sensor.

[0041] Furthermore, in existing lithotripsy procedures, the constant-pressure perfusion pump only has a single pressure sensor mounted on the main unit. Due to the small channel of the pyeloscope and the distance between the tip and the main unit, real-time pressure transmission is insufficient, and there is a pressure difference between the main unit and the tip. The present invention, however, adds a first pressure sensor 1 to the tip of the endoscope 3, allowing direct monitoring of intrarenal pressure. Simultaneously, the pressure is measured by both the first and second pressure sensors 1 and 2, and the difference between these values ​​can be used to monitor fluctuations in the values, improving data accuracy.

[0042] In addition, the perfusion system 100 further includes a first temperature sensor 6 , which is disposed at the tip of the endoscope 3 , and is configured to measure the temperature of the perfusion site.

[0043] During existing holmium laser treatments, laser lithotripsy can cause the liquid to overheat without the medical staff's knowledge, potentially harming the patient. Alternatively, during existing endoscope observations, the tip of the mirror can fog up, and the infusion of sub-body-temperature liquid can cause discomfort to the patient.

[0044] By providing a first temperature sensor 6, the temperature of the perfusion site can be monitored in real time to avoid the above-mentioned situation. When the temperature detected by the first temperature sensor 6 is too low, the temperature of the perfusion fluid in the perfusion fluid source 41 is controlled to be increased; when the temperature detected by the first temperature sensor 6 is too high, the temperature of the perfusion fluid in the perfusion fluid source 41 is controlled to be decreased. The temperature of the perfusion fluid in the perfusion fluid source 41 is T, 36°C ≤ T ≤ 40°C. More specifically, the perfusion device 4 also includes a heating device 45, which is electrically connected to the control host 5 and is used to heat the perfusion fluid in the perfusion fluid source 41. The heating device 45 heats the perfusion fluid and maintains it at temperature T, thereby improving the patient's comfort.

[0045] The perfusion system 100 also includes a second temperature sensor 7, which is disposed in the perfusion line 42 and electrically connected to the control host 5. The second temperature sensor 7 is configured to measure the temperature within the perfusion line 42. By providing both the first temperature sensor 6 and the second temperature sensor 7, fluctuations in the values ​​can be effectively monitored, reducing safety risks caused by failure of a single temperature sensor.

[0046] The perfusion system 100 also includes a suction device 8, which is connected to the endoscope 3 via a suction line 83 and is used to draw liquid from the site to be perfused. When it is necessary to aspirate the liquid in the kidney, the control host 5 controls the suction device 8 to draw the liquid. The suction device 8 includes a liquid barrel 81, a filter 82, a suction line 83, and a suction drive 84, which are connected in sequence. The liquid barrel 81 is connected to the endoscope 3, and the suction drive 84 is electrically connected to the control host 5.

[0047] In other embodiments, the perfusion system 100 further includes a liquid volume display function, a liquid volume shortage reminder function, a flow rate display function, and an idling detection function, thereby providing convenience for the operator's diagnosis / treatment.

[0048] The perfusion system 100 provided by the present invention monitors the intracavitary pressure and temperature in real time during the treatment of kidney stones, thereby automatically adjusting the perfusion flow, suction pressure, and suction flow to control the intracavitary pressure within the range set by the treating physician.

[0049] The present invention further provides a medical device, which includes the above-mentioned perfusion system 100. An embodiment of the medical device includes an embodiment of the above-mentioned perfusion system 100, and the beneficial effects of the above-mentioned perfusion system 100 can be applied to the medical device.

[0050] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative work, which should fall within the scope of protection of the present invention.
