Description

Technical Field

[0001] This invention relates to the field of pressure measurement and anti-blockage guide wire technology, specifically a temperature and pressure measurement and anti-blockage guide wire for stone surgery. Background Technology

[0002] Traditional ureteroscopic surgery cannot measure changes in renal pelvis pressure. If the renal pelvis pressure is too high, exceeding the safe threshold of 30 mmHg, it can cause serious medical accidents such as renal pelvis tissue swelling and necrosis. If the negative pressure suction is too strong, it can cause the renal pelvis space to collapse, resulting in a narrow space inside the renal pelvis, blurred vision, and inability to find the stone. It can even cause renal pelvis tissue necrosis, leading to surgical failure. During ureteroscopic lithotripsy, doctors need to use holmium / thulium lasers to break up the stones. Holmium / thulium lasers generate high heat when working, and excessive pressure and temperature can harm the patient. When using the stone suction channel to remove the stones, the broken stones can easily form stone steps that block the suction channel, leading to instantaneous renal hypertension and damaging the kidneys.

[0003] Based on this, the present invention provides a guidewire for temperature and pressure measurement and anti-blockage during stone surgery to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a guidewire for temperature and pressure measurement and anti-blockage during stone surgery, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model proposes a guide wire for temperature and pressure measurement and anti-blockage in stone surgery, including a handle. One end of the handle is connected to a data transmission line, and the other end of the handle is connected to the guide wire. The guide wire also includes a soft tip, a drain wire, a heat-shrinkable outer sheath, a core wire, a sodium hypochlorite tube, a temperature and pressure sensor, and a sensor wire. The heat-shrinkable outer sheath is filled with a core wire, and a sodium hypochlorite tube is installed inside the guide wire on the outside of the core wire. The temperature and pressure sensor is also installed inside the sodium hypochlorite tube. The temperature and pressure sensor is connected to the data transmission line through the sensor wire. The top of the guide wire is fitted with a soft tip, and a drain wire is also installed inside the guide wire on one side of the soft tip.

[0006] Preferably, the soft tip is made of polyurethane.

[0007] Preferably, the heat-shrinkable outer skin is made of polytetrafluoroethylene, and the outer side of the heat-shrinkable outer skin is coated with a nano-hydrophilic coating XZ-GT01.

[0008] Preferably, the guide wire and the hysteresis tube are both made of stainless steel or nickel-iron alloy.

[0009] Preferably, the temperature and pressure sensor, the sensor wire, and the data transmission line are electrically connected.

[0010] Compared with the prior art, the beneficial effects of the present invention are: This invention allows for convenient real-time monitoring of pressure and temperature within the renal pelvis during laser lithotripsy and negative pressure lithotripsy. During laser / holmium laser lithotripsy, the surrounding temperature can be monitored in real time to prevent thermal damage. During stone removal, medical staff can adjust the perfusion flow and negative pressure parameters based on real-time monitoring data, maintaining the pressure within the renal pelvis within a safe range. This significantly improves surgical safety, increases stone removal efficiency, and shortens surgical time. When using a stone suction channel, fragments can easily form staircases that block the suction channel, leading to instantaneous renal hypertension. Sensor monitoring allows for timely acquisition of relevant information, and the guidewire can be used to quickly clear any blockages, minimizing damage to the kidneys as quickly as possible.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0014] This utility model proposes a guide wire for temperature and pressure measurement and anti-blockage in stone surgery, including a handle 1. One end of the handle 1 is connected to a data transmission line 2, and the other end of the handle 1 is connected to a guide wire 3. The guide wire 3 also includes a soft tip 301, a drain wire 302, a heat-shrinkable outer sheath 303, a core wire 304, a hysteresis tube 305, a temperature and pressure sensor 306, and a sensor wire 307. The heat-shrinkable outer sheath 303 is filled with the core wire 304. The hysteresis tube 305 is installed inside the guide wire 3 on the outside of the core wire 304. The temperature and pressure sensor 306 is also installed inside the hysteresis tube 305. The temperature and pressure sensor 306 is connected to the data transmission line 2 through the sensor wire 307. The soft tip 301 is sleeved on the top of the guide wire 3. The drain wire 302 is also installed inside the guide wire 3 on one side of the soft tip 301.

[0015] It should also be noted that the soft tip 301 is made of polyurethane, the heat shrinkable outer skin 303 is made of polytetrafluoroethylene, the heat shrinkable outer skin 303 is coated with a nano-hydrophilic coating XZ-GT01, the guide wire 3 and the hysteresis tube 305 are both made of stainless steel or nickel-iron alloy, and the temperature and pressure sensor 306, the sensor wire 307 and the data transmission line 2 are electrically connected. In practical applications, the soft tip 301 is made of polyurethane, the heat-shrinkable outer sheath 303 is made of polytetrafluoroethylene, and the outermost layer is coated with a hydrophilic coating to ensure the lubrication of the guidewire. The core wire 3 and the hypotube 305 are made of stainless steel or nickel-iron alloy. The hypotube 305 is rotary-cut to ensure the flexibility of the guidewire. There is a groove in the hypotube within 10 cm of the tip, where a thermo-baric sensor 306 is built-in to monitor the intrarenal temperature and pressure in real time. The sensor wire 307 of the thermo-baric sensor 306 is integrated into the handle 1 along the inner wall of the hypotube 305 to transmit monitoring data. 3-4 drainage wires are placed around the circumference of the guidewire 3. The drainage wires 302 are made of nickel-iron alloy and can expand to a maximum outer diameter of 2-3 mm.

[0016] In the specific implementation method, before use, the data transmission line 2 is connected to the main unit of the device and calibrated. During ureteroscopic stone surgery, the temperature and pressure measuring guide wire 3 is placed in the renal pelvis through the stone suction channel to monitor the intrarenal pressure and temperature in real time. During the operation, relevant data can be monitored in real time, and the intrarenal pressure can be displayed on the main unit to facilitate medical staff to obtain the surrounding temperature during laser stone fragmentation to prevent thermal damage. During the negative pressure stone suction process, the intrarenal pressure is obtained in time, so as to adjust the perfusion flow rate and negative pressure parameters to ensure that the intrarenal pressure is within the safe threshold while increasing the stone clearance efficiency of the stone surgery with appropriate perfusion flow rate and negative pressure parameters. If the stone suction channel is blocked and the intrarenal pressure rises suddenly, the real-time pressure data can be used to judge and use the unblocking method 302 to quickly unblock the stone suction channel and keep it unobstructed.
