Therefore, the resistance of the ureter needs to be monitored during treatment. For some smaller stones, if the ureteral resistance increases slightly, conservative treatment can be tried first, such as drinking more water, exercising more, and taking medicine to expel the stones; if the resistance increases significantly, more active treatments such as extracorporeal shock wave lithotripsy or surgical stone removal may be required.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0033] Example

[0034] Reference Figure 1-Figure 6 The present invention provides a technical solution: a ureteral resistance monitor, including an outer tube 1 and a monitoring mechanism 3, a first connecting rod 2 is slidably installed inside the outer tube 1, the monitoring mechanism 3 includes a pressure sensor 31, the pressure sensor 31 is stably installed at the bottom end of the outside of the first connecting rod 2, a flow monitor 32 is installed below the pressure sensor 31, and is used to monitor the flow of liquid input, a camera 33 is fixedly installed at one end of the first connecting rod 2, and a limit baffle 331 is fixedly installed on the outer surface of the first connecting rod 2.

[0035] The device can monitor the resistance inside the ureter. By monitoring the internal pressure and liquid flow of the ureter, the resistance inside the ureter can be obtained, so that medical staff can find problems in time and solve them, avoiding serious discomfort for patients when urinating. The device will pass the flow monitor 32 through the obstructed position and move the pressure sensor 31 to the position outside the obstruction. Since the flow rate of the liquid in the ureter is reduced, the liquid flow will be monitored by the flow monitor 32, so that the internal resistance of the ureter can be monitored in real time through the changes in liquid flow and changes in the internal pressure of the ureter.

[0036] In a preferred embodiment, the pressure sensor 31 and the flow monitor 32 are electrically connected to the control computer 4. The pressure sensor 31 is embedded in the first connecting rod 2, and the detection end of the pressure sensor 31 extends out of the first connecting rod 2. In order to facilitate medical staff to clearly understand the pressure and liquid flow inside the ureter, the device is provided with a control computer 4 on the outside. The pressure value and flow value will be displayed on the control computer 4, so that the two values ​​can facilitate medical staff to understand the cleaning of the inside of the ureter for targeted treatment.

[0037] In a preferred embodiment, two infusion tubes 5 are installed on the outer surface of the outer tube 1. The interior of the infusion tubes 5 is connected to the interior of the outer tube 1 for transporting physiological saline, and the physiological saline is arranged on the outside of the first connecting rod 2. The opening of the infusion tube 5 is provided with a plug-connected sealing plug 6. When the device monitors the internal resistance of the ureter of the patient, the physiological saline will be transported to the interior of the outer tube 1 through the interior of the infusion tube 5, and the outer tube 1 will be extended into the interior of the ureter so as to transport the physiological saline to the interior of the ureter, and the physiological saline is transported inside the ureter, and the flow rate and pressure are monitored so as to monitor the resistance inside the ureter in real time.

[0038] In a preferred embodiment, a rubber arc plate 7 is fixedly installed at one end of the first connecting rod 2. The rubber arc plates 7 are arranged in plurality and are evenly arranged at the bottom of the first connecting rod 2. The plurality of rubber arc plates 7 form a clamp for clamping stones. In actual use, if there are a small amount of stones in the ureter, the rubber arc plate 7 can be controlled to move to the position where the stones are while the first connecting rod 2 is moving. The rubber arc plates 7 are arranged in plurality and form a clamp approximating the same, and the port is relatively small. The stones can be squeezed into the interior of the rubber arc plate 7 by controlling the rubber arc plate 7. When the first connecting rod 2 is subsequently pulled out, the stones can be taken out for easy use.

[0039] Since the inside of the ureter is relatively sensitive, the ureter may be damaged if not handled with care. To avoid damage to the ureter, the device controls the distance that the first connecting rod 2 moves in the ureter by installing an anti-overextension mechanism 8 inside the outer tube 1. The anti-overextension mechanism 8 includes a slide rail 81 and a block 82. The slide rail 81 is fixedly mounted on the inner wall of the outer tube 1, and the block 82 is fixedly mounted at the bottom of the slide rail 81. An opening is provided on one side of the limit baffle 331, and the limit baffle 331 is stuck on the slide rail 81 to slide.

[0040] In actual use, in order to prevent the first connecting rod 2 from moving too deep and touching the inner wall of the ureter and causing damage to the inner wall of the ureter, the first connecting rod 2 will be restricted by the block 82 when moving, and the limit baffle 331 will move stably on the slide rail 81. When the limit baffle 331 touches the position of the block 82, the first connecting rod 2 will not move anymore, thereby avoiding damage to the ureter.

[0041] The outer tube 1 needs to be replaced after one use and cannot be used any further to avoid infection to the patient. Therefore, a circular plate 9 is slidably installed on the outside of the first connecting rod 2, and a mounting mechanism 10 is arranged on the circular plate 9. The mounting mechanism 10 includes a hook 101, a torsion spring 102 and a rectangular hole 103. A vertical plate 11 is fixedly installed on the bottom of the circular plate 9, and a round rod 12 is fixedly installed on the inner side of the vertical plate 11. A torsion spring 102 is arranged on the outside of the round rod 12, and a plurality of round rods 12 are arranged and evenly arranged at the bottom of the circular plate 9. A torsion spring 102 is installed on each round rod 12. A plurality of rectangular holes 103 are opened at the upper end of the outer surface of the outer tube 1 and are evenly arranged on the outer surface of the outer tube 1. The outer surface of the round rod 12 is rotatably connected with a hook 101, and the hook 101 is hooked inside the rectangular hole 103.

[0042] In actual use, in order to avoid infection, the outer tube 1 will be replaced. When replacing the outer tube 1, the first connecting rod 2 needs to be taken out from the inside of the outer tube 1, and the hook 101 is rotated to detach the hook 101 from the outer tube 1, so that the outer tube 1 can be removed from the circular plate 9. When installing a new outer tube 1, the end of the outer tube 1 is directly pressed against the bottom of the circular plate 9. Under the action of the torsion spring 102, the hook 101 will be controlled to rotate. When the position of the hook 101 corresponds to the rectangular hole 103, the hook 101 will automatically move into the rectangular hole 103 and hook the outer tube 1 so that the overall stable use can be achieved, thereby protecting the patient from infection.

[0043] In order to ensure the stable use of the flow monitor 32, a circular plate 13 is fixedly installed at the bottom end of the first connecting rod 2, a second connecting rod 14 is fixedly installed at the bottom of the circular plate 13, and the flow monitor 32 is fixedly installed at the bottom of the first connecting rod 2 for stable use of the flow monitor 32.

[0044] By setting up a control computer 4, data collection is facilitated, and the collected data is displayed on the control computer 4. For ease of use, a handle 15 is fixedly connected to the outer end of the first connecting rod 2, and an electric wire 16 is set inside the first connecting rod 2. The electric wire 16 is connected to the flow monitor 32, the pressure sensor 31 and the camera 33 to power the three. The electric wire 16 extends from the inside of the first connecting rod 2 to the outside of the first connecting rod 2. The flow monitor 32, the pressure sensor 31 and the camera 33 are connected to the control computer 4 through the electric wire 16 to form a system for use by medical staff.

[0045] Specifically, the working process or working principle of a ureteral resistance monitor is as follows: currently, most ureteral detection methods are to insert a medical camera 33 into the ureter, extend the medical camera 33 into the ureter to monitor the internal situation, and view the internal situation of the ureter through an external terminal device, that is, to observe the stones inside the ureter and the number of stones to facilitate subsequent treatment. However, the resistance inside the ureter cannot be monitored, and the patient experiences strong discomfort when urinating, so this device is designed to solve this problem.

[0046] The resistance inside the ureter can be monitored by this device. By monitoring the internal pressure and liquid flow of the ureter, the resistance inside the ureter can be obtained, so that medical staff can find problems in time and solve them to avoid serious discomfort for patients when urinating. The specific operation is to connect to an external power supply. The device displays the data on the control computer 4. When the patient is tested, the corresponding data can be viewed in real time. A staff member inserts the outer tube 1 into the patient's ureter. After entering the ureter, the staff member adds saline from the infusion tube 5 to the position inside the outer tube 1, and transports the saline from the inside of the outer tube 1 to the inside of the ureter. At the same time, the first connecting rod 2 is moved inside the outer tube 1, and the bottom end of the first connecting rod 2 is extended into the inside of the ureter to monitor the resistance inside the ureter.

[0047] If there is obstruction or a large number of stones inside the ureter, the flow of saline will be hindered and the flow rate of saline inside the ureter will be reduced. The device will pass the flow monitor 32 through the obstructed position and move the pressure sensor 31 to a position outside the obstruction. Since the flow rate of the liquid inside the ureter is reduced, the liquid flow will be monitored by the flow monitor 32 and the flow value will be displayed on the control computer 4 so that medical staff can observe the liquid flow value.

[0048] In order to improve the monitoring effect of ureteral resistance, when the liquid slowly flows to the deep part of the ureter, a large amount of liquid will accumulate outside the obstruction in the ureter, which will cause the pressure at that position to increase. The water pressure will squeeze the pressure sensor 31, causing the pressure sensor 31 to detect a certain pressure. When the pressure exceeds the set value, medical staff will take action.

[0049] By monitoring liquid flow and liquid pressure, the resistance inside the ureter can be monitored in real time, so that medical staff can detect problems in time and provide targeted treatment to patients.

[0050] Since the bottom end of the first connecting rod 2 will move inside the ureter, in order to prevent the first connecting rod 2 from moving too deep and touching the inner wall of the ureter and causing damage to the inner wall of the ureter, the first connecting rod 2 will be restricted by the block 82 when moving, and the limit baffle 331 will move stably on the slide rail 81. When the limit baffle 331 touches the position of the block 82, the first connecting rod 2 will not move anymore, thereby avoiding damage to the ureter.

[0051] In addition, during the movement of the first connecting rod 2, the device will use the camera 33 to photograph the inside of the ureter, which is convenient for medical staff to observe the situation inside the ureter, so as to understand the situation of stones inside the ureter and facilitate medical staff to formulate corresponding treatment plans. If there are not many stones in the ureter and the size is small, the rubber arc plate 7 can be used to clamp the stones and the stones can be directly removed.

[0052] The outer tube 1 is inserted into the patient's ureter. When it is used again later, the outer tube 1 will be replaced to avoid infection. When the outer tube 1 is replaced, the first connecting rod 2 needs to be taken out from the inside of the outer tube 1, and the hook 101 is rotated to detach the hook 101 from the outer tube 1, so that the outer tube 1 can be removed from the circular plate 9. When the new outer tube 1 is installed, the end of the outer tube 1 is directly pressed against the bottom of the circular plate 9. Under the action of the torsion spring 102, the hook 101 will be controlled to rotate. When the position of the hook 101 corresponds to the rectangular hole 103, the hook 101 will automatically move into the rectangular hole 103 and hook the outer tube 1 so that the overall stable use can be avoided to cause infection to the patient.
