Description

Technical Field

[0001] The present application belongs to the technical field of interventional surgery catheters, and specifically is an interventional surgery catheter shaping device and a shaping method thereof. Background Art

[0002] Currently, interventional catheters are a common choice for superselective angiography and embolization of small blood vessels in vascular interventional surgery. However, due to the irregular morphology, tortuous course and small size of peripheral blood vessels and neurovascular vessels, ordinary catheters are unable to achieve superselection due to their thicker diameter and tougher material. In this case, interventional catheters are needed to superselect blood vessels for angiography and treatment. Interventional catheters are used more frequently in neurointerventional treatments, especially in interventional coil embolization of intracranial aneurysms, which require higher superselectivity for microcatheters. Some of the tips of some clinical microcatheter products have been pre-shaped at 45° and 90°, but they are only suitable for a small number of cases. In most cases, the use of microcatheters requires clinicians to perform post-shaping based on the vascular shape shown by intraoperative angiography.

[0003] The catheter shaping device and shaping component disclosed in Chinese invention patent CN115192855A include a heating sleeve and a universal tube. A heating wire is arranged in the heating sleeve. The universal tube is formed by a plurality of universal joints which are connected in sequence. Two adjacent universal joints are connected in sequence and can rotate relatively. A longitudinally through heating tube cavity is formed in the universal tube. The heating sleeve is arranged in the heating tube cavity. A longitudinally through catheter cavity is arranged in the heating sleeve. The shaping device has low shaping efficiency and poor shaping effect.

[0004] In the prior art, medical staff only rely on water vapor to shape the end of the interventional surgery catheter. This shaping process has low precision and is difficult, and there is a risk of hand burns for medical staff during the shaping process.

[0005] Since the boiling water inside the boiling chamber needs to be in a boiling state for a long time and form water vapor, and the amount of boiling water and the heating temperature inside the boiling chamber are constantly changing, the amount of water vapor formed is constantly changing accordingly, and the heating and shaping efficiency of the water vapor on the end of the interventional surgery catheter is constantly changing, which will reduce the heating and shaping quality of the end of the interventional surgery catheter.

[0006] When used for a long time, a large amount of dust and impurities are likely to adhere to the inside of the exhaust hole, which can easily contaminate the end of the interventional surgery catheter. When the boiling water in the boiling chamber is in a boiling state for a long time, the impurities in the boiling water will adhere to the inner wall of the kettle body to form scale, which will not only affect the cleanliness of the inner wall of the kettle body, but also the water vapor formed will carry impurities, which can easily contaminate the end of the interventional surgery catheter.

[0007] And when the water vapor moves upward, most of the water vapor will adhere to the bottom of the kettle lid and form water droplets, and too many water droplets cannot fall back into the kettle body to boil, which will not only cause the water vapor to be unable to be discharged along the exhaust hole and heat and shape the interventional surgical catheter, but also cause the boiling water inside the kettle body to dry up quickly and require multiple refills, and ultimately reduce the shaping efficiency of the interventional surgical catheter.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] First embodiment

[0044] like Figure 1-3 As shown, an interventional surgical catheter shaping device includes a kettle body 1, a boiling chamber 11 is arranged inside the kettle body 1, a kettle cover 2 is arranged on the top of the kettle body 1, and a controller is arranged on one side of the kettle body 1 and the kettle cover 2. The controller electrically controls each electrical component. The kettle body 1 and the kettle cover 2 are mutually clamped to form a boiling chamber 11 in a sealed state, thereby further improving the shaping effect and shaping efficiency of the interventional surgical catheter.

[0045] Boiling water is provided inside the boiling chamber 11, and a heating seat is provided at the bottom of the kettle body 1. When the controller controls the heating seat to start, the heating seat applies a heating effect to the kettle body 1, and the water added inside the boiling chamber 11 is continuously heated to form boiling water. A sealing pad 12 is provided on the inner wall of the kettle cover 2, and the outer wall of the sealing pad 12 matches the inner wall of the boiling chamber 11. The setting of the sealing pad 12 further improves the sealing performance of the kettle body 1 and the kettle cover 2, and the sealing pad 12 is often made of high temperature resistant material, so it meets the actual use requirements.

[0046] A workbench 3 is provided on the top of the pot lid 2, and a plurality of exhaust holes 4 are evenly opened on the workbench 3. The interventional surgery catheter is placed on the top of the workbench 3 for shaping. At the same time, since the density of boiling water is less than the density of air, the boiling water inside the boiling chamber 11 forms water vapor and reaches the top of the pot lid 2 upward, and is further discharged along the plurality of exhaust holes 4 inside the workbench 3 to heat the interventional surgery catheter. The temperature of the interventional surgery catheter continues to rise. At this time, the medical staff manually pinches the interventional surgery catheter into the required shape structure according to the patient's blood vessel shape observed by surgical angiography, and completes the required shaping process.

[0047] When in use, first add a proper amount of water into the boiling chamber 11 of the kettle body 1, then put the kettle lid 2 on the top of the kettle body 1, and use the sealing rubber pad 12 to further improve the sealing of the kettle body 1 and the kettle lid 2. After the assembly is completed, the controller controls the heating seat to start, and the heating seat boils the water in the boiling chamber 11, and the water vapor formed after boiling reaches the top of the kettle lid 2, and is finally discharged along the multiple exhaust holes 4 inside the workbench 3.

[0048] At the same time, in order to improve the accuracy of interventional surgery, it is first necessary to perform vascular angiography on the patient, and obtain the vascular shape structure of the surgical position based on the results of the angiography. At this time, the end of the interventional surgery catheter is shaped with the help of the shape structure, thereby improving the passability of the interventional surgery catheter and reducing the damage of the end of the interventional surgery catheter to the inner wall of the patient's blood vessel. The angiography structure and the shape and size of the end of the interventional surgery catheter that need to be shaped are known. Then, the medical staff places the interventional surgery catheter on the workbench 3, and the high-temperature water vapor is discharged along the exhaust hole 4 to soften the interventional surgery catheter. The softened interventional surgery catheter is kneaded and shaped under the manual operation of the medical staff, and then the end of the interventional surgery catheter is kneaded into the required shape and size. After the shaping is completed, the end of the interventional surgery catheter is placed in low-temperature cooling water for rapid cooling and shaping, and finally the required interventional surgery catheter end is formed.

[0049] The shaping device has high shaping efficiency and good shaping effect, meets actual shaping needs, ensures that the end of the interventional surgery catheter meets the patient's vascular intervention requirements, is simple to operate, highly controllable, stable and efficient, and has good continuous shaping effect, stability and efficiency, and strong adaptability.

[0050] Second embodiment

[0051] like Figure 4-9 As shown, in the above technology, when only the medical staff manually shapes the end of the interventional surgery catheter, the shaping accuracy is low, the shaping difficulty is great, and the medical staff is at risk of hand burns during the shaping process; and because the boiling water inside the boiling chamber 11 needs to be in a boiling state for a long time and form water vapor, and the amount of boiling water and the heating temperature inside the boiling chamber 11 are constantly changing, the amount of water vapor formed is constantly changing accordingly, and the heating shaping efficiency of the end of the interventional surgery catheter by the water vapor is constantly changing, further reducing the heating shaping quality of the end of the interventional surgery catheter; and when used for a long time, a large amount of dust and impurities are easily attached to the inside of the exhaust hole 4, and the dust and impurities are easy to cause pollution to the end of the interventional surgery catheter, thereby reducing the subsequent interventional surgery catheter. The quality of interventional surgery inside the patient's blood vessels; and because the boiling water in the boiling chamber 11 is in a boiling state for a long time, the impurities in the boiling water will adhere to the inner wall of the kettle body 1 to form scale, which will not only affect the cleanliness of the inner wall of the kettle body 1, but also the water vapor formed will carry impurities and easily cause pollution to the end of the interventional surgery catheter; and when the water vapor moves upward, most of the water vapor will adhere to the bottom of the kettle cover 2 and form water droplets, and too many water droplets cannot fall back into the kettle body 1 to boil, which not only causes the water vapor to be unable to be discharged along the exhaust hole 4 and heat and shape the interventional surgery catheter above the workbench 3, but also causes the boiling water inside the kettle body 1 to dry up quickly and require multiple replenishments, ultimately reducing the shaping efficiency of the interventional surgery catheter.

[0052] In order to solve the above problems, the interventional surgery catheter shaping device also includes: a rotating shaft 15 is rotatably connected to the axis of the boiling chamber 11, and a plurality of stirring rods 16 are evenly arranged on the outer surface of the rotating shaft 15. When the rotating shaft 15 rotates, the plurality of stirring rods 16 are driven to rotate. The stirring rods 16 can not only stir the boiling water inside the boiling chamber 11, thereby improving the heating uniformity of the boiling water and the efficiency of the water vapor floating upward, but also can scrape and clean the inner wall of the boiling chamber 11, so as to avoid the formation of scale and the like attached to the inner wall of the boiling chamber 11 when the boiling water is boiled for a long time, and finally reduce the boiling efficiency of the boiling water and the pollution of the water vapor.

[0054] A side groove 17 is provided on the opposite side of the stirring rod 16 on the same side, that is, the side groove 17 is mainly provided at the top of the stirring rod 16 at the top and the bottom of the stirring rod 16 at the bottom. A sliding rod 19 is slidably connected inside the side groove 17. The sliding rod 19 can slide along the side groove 17, thereby not only achieving the irregular stirring efficiency of the boiling water inside the boiling chamber 11, but also being able to thoroughly and effectively scrape and clean the inner wall of the boiling chamber 11, thereby ensuring the cleanliness of the boiling water inside the boiling chamber 11.

[0055] An elastic block 18 is provided on the inner wall of the side groove 17, and the other end of the elastic block 18 is fixedly connected to the side wall of the sliding rod 19. With the help of the elastic block 18, the elastic reset performance of the sliding rod 19 in the side groove 17 is further improved. An elastic cleaning rod 20 is provided on one end of the sliding rods 19 on the same side away from the elastic block 18. The height of the elastic cleaning rod 20 matches the height of the inner wall of the boiling chamber 11. The elastic cleaning rod 20 can stir the boiling water in the boiling chamber 11 in the vertical direction, thereby improving the efficiency of the water vapor formed by the boiling water in the boiling chamber 11 floating upward, and when the elastic cleaning rod 20 is When the cleaning rod 20 and the inner wall of the boiling chamber 11 are squeezed and contacted with each other, the sliding rod 19 drives the elastic cleaning rod 20 to rotate and further improves the scraping and cleaning effect of the inner wall of the boiling chamber 11. The sum of the lengths of the stirring rod 16 and the sliding rod 19 matches the radius value of the boiling chamber 11. The bottom of the sliding rod 19 below contacts the inner bottom of the boiling chamber 11. When the sliding rod 19 moves outward along the side groove 17 to the maximum distance, the sliding rod 19 cooperates with the stirring rod 16 to thoroughly and effectively scrape the inner bottom of the boiling chamber 11, thereby preventing boiling water from boiling at the inner bottom of the boiling chamber 11 and forming scale.

[0056] A plurality of fixed sleeves 5 are evenly arranged on the top of the workbench 3. An electromagnetic ring 9 is arranged on the top of the fixed sleeve 5.

At the same time, the magnetism of the end faces facing the electromagnetic ring 9 and the magnetic support block 7 is different. The height of the piston rod 6 matches the height of the air storage chamber 24. When the current of the electromagnetic ring 9 increases continuously, the magnetism of the electromagnetic ring 9 increases continuously. The magnetic attraction force applied by the electromagnetic ring 9 to the magnetic support block 7 increases continuously and drives the magnetic support block 7 to move downward. The magnetic support block 7 drives the clamping assembly 8 on the top to move downward. At the same time, the magnetic support block 7 synchronously drives the piston rod 6 to move downward along the air storage chamber 24, and the internal space of the air storage chamber 24 is reduced.

[0057] A support spring 10 is provided at the top of the electromagnetic ring 9. The top of the support spring 10 is fixedly connected to the bottom of the magnetic support block 7. The support spring 10 is located on the outer surface of the piston rod 6.

This arrangement further ensures the stability of the sealing sliding of the elastic connection block 14 at the bottom of the pot cover 2, and the sizes of the limit groove and the limit block are very small, so they will not affect the normal upward flow of water vapor at the bottom of the pot cover 2. One side of the elastic connection block 14 is evenly provided with multiple groups of elastic brush groups, and the elastic brush groups correspond to the exhaust holes 4. Therefore, when the elastic connection block 14 moves laterally at the bottom of the pot cover 2, the exhaust holes 4 are scraped and cleaned with the help of the elastic brush groups, further improving the scraping and cleaning effect of the blocked exhaust holes 4, avoiding external dust and impurities from entering the exhaust holes 4 when the exhaust holes 4 are not working to cause pollution, and affecting the heating and shaping of the end of the subsequent interventional surgery catheter.

[0061] A plurality of vertical rods 30 are evenly arranged at the bottom of the elastic connecting block 14, and the positions of the vertical rods 30 correspond to the positions of the magnetic push blocks 29. A pressure sensor is arranged at the bottom of the vertical rods 30, and the pressure sensor is used to detect the pressure value received at the bottom of the vertical rods 30. A ferromagnetic rod 31 is arranged at the top of the upper sliding rod 19, and the top of the ferromagnetic rod 31 matches the bottom of the vertical rod 30. When the sliding rod 19 drives the ferromagnetic rod 31 to rotate continuously, the ferromagnetic rod 31 continuously squeezes and contacts with the vertical rod 30, and the pressure value detected by the pressure sensor continuously changes. The top of the ferromagnetic rod 31 and the bottom of the vertical rod 30 are both provided with rounded corners, and the setting of the rounded corners further improves the passability of the ferromagnetic rod 31 and the vertical rod 30 to squeeze and collide with each other. The ferromagnetic rod 31 matches the magnetic push block 29, and the ferromagnetic rod 31 has ferromagnetism attracted by a magnet. When the thermal expansion tube 28 drives the magnetic push block 29 to move laterally at the bottom of the pot cover 2, the position of the magnetic push block 29 changes. When the stirring rod 16 drives the sliding rod 19 to rotate, the sliding rod 19 drives the ferromagnetic rod 31 to rotate synchronously. With the help of the magnetic attraction of the magnetic push block 29 on the ferromagnetic rod 31 and the rotation of the ferromagnetic rod 31 around the rotating shaft 15, the position of the ferromagnetic rod 31 inside the boiling chamber 11 keeps changing. The ferromagnetic rod 31 drives the sliding rod 19 to slide inside the side groove 17 accordingly, and the sliding rod 19 drives the elastic cleaning rod 20 to move and scrape and clean the inner wall of the boiling chamber 11.

[0062] When in use, firstly, all components of the device are installed according to the first embodiment, and water is added into the boiling chamber 11, and the kettle cover 2 and the kettle body 1 are squeezed and covered tightly. Since the stirring rod 16 is in the initial position when not working, the sliding rod 19 drives the ferromagnetic rod 31 to be in the initial position, and the bottom of the vertical rod 30 and the top of the ferromagnetic rod 31 are squeezed and contacted with each other, and the pressure value detected by the pressure sensor reaches the preset pressure value. Since the water in the boiling chamber 11 is not in a boiling and low temperature state at this time, the temperature value of the bottom of the kettle cover 2 is low, the volume of the thermal expansion tube 28 is in the initial state, the two sides of the fixing seat 26 are in contact with the side walls of the two elastic connecting blocks 14, and the multiple exhaust holes 4 in the workbench 3 are all blocked by the elastic air guide sheet 13. Then, the end of the interventional surgery catheter is passed through multiple clamping rings 801, and the controller controls multiple electric push rods 802 to start and drive the elastic gasket 803 at the output end to squeeze and contact with the outer surface of the interventional surgery catheter, further completing the fixing of the end of the interventional surgery catheter, thereby improving the efficiency of subsequent shaping thereof.

[0063] Afterwards, the controller controls the heating seat to work continuously and boil the water inside the boiling chamber 11. After boiling, the water forms water vapor and reaches the bottom of the elastic air guide sheet 13 upward, and is continuously gathered to the end of the thermal expansion tube 28 under the guidance of the elastic air guide sheet 13. The thermal expansion material inside the thermal expansion tube 28 expands due to the heat, and the volume of the thermal expansion tube 28 increases and drives the magnetic push block 29 at the end to move away from the fixed seat 26 end. When the magnetic push block 29 moves, it simultaneously drives the elastic connecting block 14 to move away from each other. The two elastic connecting blocks 14 drive the elastic air guide sheet 13 to move away from each other in the upper direction and continuously break away from the blockage of the exhaust hole 4. Then, the water vapor is discharged upward along the exhaust hole 4 and heats and shapes the end of the interventional surgery catheter inside the clamping assembly 8, further improving the shaping efficiency and shaping effect.

[0064] At the same time, the controller controls the drive motor 22 to start, and the output end of the drive motor 22 drives the rotating shaft 15 to rotate through the transmission shaft 23, and the rotating shaft 15 drives multiple stirring rods 16 to rotate, and the stirring rod 16 drives the sliding rod 19 inside the side groove 17 to rotate and horizontally stir the boiling water inside the boiling chamber 11, and the sliding rod 19 drives the elastic cleaning rod 20 to vertically stir the boiling water inside the boiling chamber 11, further improving the upward flow rate of water vapor formed by boiling water, and improving the heating and shaping efficiency of water vapor on the end of the interventional surgery catheter, and the rotation of the sliding rod 19 can also improve the mixing effect of the water inside the boiling chamber 11, to avoid uneven heating of the water inside the boiling chamber 11, thereby reducing the effect of subsequent water vapor formation.

[0065] When the water vapor content formed by the boiling water inside the boiling chamber 11 for a long time decreases, the amount of water vapor reaching the ends of the multiple heat expansion tubes 28 under the guidance of the elastic air guide sheet 13 decreases, and the heat exchange efficiency of the corresponding water vapor to the heat expansion material inside the heat expansion tube 28 is reduced. The temperature of the heat expansion material inside the heat expansion tube 28 drops and drives the volume of the heat expansion tube 28 to decrease, then the volume of the heat expansion tube 28 decreases, the heat expansion tube 28 drives the elastic connecting block 14 to move toward each other through the magnetic push block 29, the elastic connecting block 14 drives the elastic air guide sheet 13 to move synchronously, the inclination angle of the elastic air guide sheet 13 increases, and the blockage area of ​​the exhaust hole 4 by the elastic air guide sheet 13 increases, the water vapor formed by the boiling water inside the boiling chamber 11 is continuously concentrated in the middle and discharged along the multiple exhaust holes 4 in the middle, avoiding the loss caused by excess water vapor, further ensuring the accuracy and stability of the water vapor heating and shaping of the interventional surgery catheter inside the clamping assembly 8, thereby avoiding the change of the water vapor amount and thus affecting the heating and shaping quality of the interventional surgery catheter.

[0066] In particular, when the amount of water vapor generated by boiling water inside the boiling chamber 11 increases, the volume of the heat expansion tube 28 increases, and the distance that the heat expansion tube 28 drives the elastic connecting block 14 to move in opposite directions through the magnetic push block 29 increases, and the elastic connecting block 14 drives the opening area above the two elastic air guide sheets 13 to increase, and the blockage of the exhaust holes 4 by the elastic air guide sheets 13 decreases, and the excess water vapor is discharged along the multiple exhaust holes 4. On the basis of ensuring the heating and shaping requirements of the end of the interventional surgery catheter inside the clamping assembly 8 by water vapor, excess water vapor can be discharged stably, avoiding the interventional surgery catheter from being exposed to too much water vapor, thereby affecting its normal heating and shaping effect, and causing damage to the end of the interventional surgery catheter.

[0067] When the thermal expansion tube 28 drives the elastic connecting block 14 to move back and forth horizontally at the bottom of the pot cover 2 through the magnetic pushing block 29, the elastic connecting block 14 simultaneously drives the multiple elastic brush groups to move back and forth horizontally at the bottom of the pot cover 2. The elasticity of the elastic brush group itself can be used to scrape and clean the multiple exhaust holes 4, further improving the cleanliness and dust-freeness of the exhaust holes 4, avoiding the pot cover 2 from being exposed to the outer surface for a long time, causing external dust and impurities to adhere to the inside of the exhaust holes 4, and subsequent dust and impurities to pollute the water vapor, thereby reducing the cleanliness of the interventional surgery catheter. The overall cleaning efficiency is higher and the cleaning effect is better, which effectively improves the interventional surgery effect of the interventional surgery catheter on the patient.

[0068] After the heating of the end of the interventional surgical catheter is completed, it needs to be shaped. The shape and size of the interventional surgical catheter that needs to be bent is obtained in advance as mentioned above. At this time, the controller controls the electromagnetic ring 9 at the corresponding position to be energized and the energizing current increases. The electromagnetic ring 9 has magnetism and increases the magnetic attraction of the magnetic support block 7. The magnetic support block 7 squeezes the support spring 10 and moves downward. The magnetic support block 7 simultaneously drives the clamping assembly 8 at the top to move downward. The clamping assembly 8 drives the interventional surgical catheter to move downward at this position, and cooperates with multiple magnetic support blocks 7 to drive the clamping assembly 8 to move downward synchronously, ensuring that the end of the interventional surgical catheter forms the required C-shaped or S-shaped structure, thereby improving the shaping accuracy and shaping efficiency, and avoiding the problems of shaping difficulty and low shaping accuracy caused by artificial shaping.

[0069] At the same time, when the magnetic support block 7 moves downward, the magnetic support block 7 drives the piston rod 6 to move downward along the air storage chamber 24, and the gas inside the air storage chamber 24 is squeezed and reaches the inside of the transfer chamber 27 along the flow hole 25. The gas inside the transfer chamber 27 enters the inside of the heat expansion tube 28, and the volume of the heat expansion tube 28 increases and drives the magnetic push block 29 at the end to move away from the fixed seat 26. The magnetic push block 29 simultaneously drives the elastic connection block 14 to move in opposite directions at this position, and the elastic connection block 14 drives the elastic air guide sheet 13 to move synchronously. Then, at this position, the blockage amount of the exhaust hole 4 by the elastic air guide sheet 13 is reduced, and the water vapor inside the boiling chamber 11 is discharged upward along the exhaust hole 4 at this position. The heating efficiency of the interventional surgery catheter at this position is correspondingly improved, and the clamping assembly 8 cooperates with the downward stretching effect of the interventional surgery catheter at this position, thereby realizing the shaping of the interventional surgery catheter at this position, further improving the shaping effect, ensuring the shaping efficiency, and meeting the actual shaping needs.

[0070] And when the heat expansion tube 28 drives the magnetic push block 29 to move, the position between the magnetic push block 29 and the fixed seat 26 changes synchronously, then the magnetic attraction of the magnetic push block 29 and the ferromagnetic rod 31 drives the ferromagnetic rod 31 to move synchronously, the ferromagnetic rod 31 drives the sliding rod 19 to slide inside the side groove 17, the extension distance of the sliding rod 19 changes continuously, and the rotating shaft 15 drives the stirring rod 16 to rotate, the stirring rod 16 drives the ferromagnetic rod 31 to rotate synchronously while driving the sliding rod 19 to rotate, the extension distance of the sliding rod 19 inside the boiling chamber 11 changes and cooperates with its own rotation, effectively applying irregular stirring to the inside of the boiling chamber 11, effectively improving the stirring and mixing effect of the boiling water inside the boiling chamber 11, not only improving the discharge efficiency of water vapor in the boiling water, but also preventing the boiling water from precipitating and forming scale during the boiling process, with stronger cleaning performance and higher stability.

[0071] At the same time, when the ferromagnetic rod 31 rotates with the sliding rod 19, it constantly collides with multiple vertical rods 30, and the pressure value detected by the pressure sensor keeps changing. With the help of the collision, the vertical rod 30 is driven to shake under the pot cover 2, and the vertical rod 30 simultaneously drives the elastic air guide sheet 13 to shake under the pot cover 2, so that the water droplets attached to the bottom of the elastic air guide sheet 13 are quickly shaken off and flow back into the boiling chamber 11, avoiding the water vapor reaching the bottom of the elastic air guide sheet 13 and forming water droplets, causing the boiling water in the boiling chamber 11 to continuously decrease, and finally causing dry burning, effectively reducing the number of subsequent water replenishment times, and ensuring that the boiling water in the boiling chamber 11 can thoroughly and effectively form water vapor and heat and shape the end of the interventional surgery catheter.

[0072] When the ferromagnetic rod 31 continuously rotates and collides with the multiple vertical rods 30, the maximum pressure value detected by the pressure sensor is equal to the set pressure preset value. When the maximum pressure value detected by the pressure sensor is not equal to the set pressure preset value, it means that the position of the vertical rod 30 is raised at this time, and the corresponding position of the pot lid 2 is too high, then the sealing between the pot lid 2 and the pot body 1 does not meet the requirements, and the position of the pot lid 2 needs to be adjusted to ensure the subsequent tightness between the pot lid 2 and the pot body 1 and the quality of water vapor formed by boiling water in the boiling chamber 11.

[0073] Furthermore, when it is necessary to clean the inner wall of the boiling chamber 11, it is only necessary to add a maximum amount of water into the boiling chamber 11. Then, the amount of water vapor formed after the water in the boiling chamber 11 is boiled reaches a maximum, and the controller controls the current of the electromagnetic ring 9 to reach a maximum value. The electromagnetic ring 9 drives the magnetic support block 7 to move downward to a maximum distance. The magnetic support block 7 drives the piston rod 6 to move downward along the gas storage chamber 24 to a maximum distance. The hot expansion gas in the gas storage chamber 24 enters the heat expansion tube 28 along the flow hole 25 and the transfer chamber 27. Then, the hot expansion gas in the heat expansion tube 28 reaches a maximum volume under the heat exchange of water vapor. The volume of the heat expansion tube 28 reaches a maximum value synchronously. The heat expansion tube 28 drives the magnetic push block 29 at the end to move away from each other to a maximum distance. The magnetic attraction of the magnetic push block 29 and the ferromagnetic rod 31 drives the ferromagnetic rod 31 to move away from the rotating shaft 15 to a maximum distance. The ferromagnetic rod 31 drives the sliding rod 19 to move away When the end of the rotating shaft 15 moves to the maximum distance, the sliding rod 19 drives the elastic cleaning rod 20 to move to the maximum distance and fits with the inner wall of the boiling chamber 11. At the same time, the sliding rod 19 below slides out the maximum distance along the side groove 17 and cooperates with the stirring rod 16 to contact the inner bottom of the boiling chamber 11. At this time, the rotating shaft 15 drives the stirring rod 16 to rotate, and the stirring rod 16 drives the sliding rod 19 and the elastic cleaning rod 20 to rotate, further realizing the thorough and effective scraping and cleaning of the inner wall of the boiling chamber 11. Since the elastic air guide sheet 13 no longer blocks the exhaust hole 4, the water vapor formed by the boiling water reaches the inside of the multiple exhaust holes 4 upward and is finally discharged upward, thereby steam cleaning the exhaust holes 4, effectively improving the cleanliness and dust-freeness of each structure, and avoiding pollution to subsequent use. After cleaning, it is only necessary to stop the heating seat, open the pot cover 2 and pour out the boiling water in the boiling chamber 11, and place the pot body 1 and the pot cover 2 in a dust-free environment and wait for the next use.

[0074] The device is easy to operate, has high heating and shaping efficiency, and has good heating and shaping effect. It can meet the shaping requirements of interventional surgical catheters of different shapes and sizes, and has stronger adaptability and higher stability. At the same time, the positions of the elastic connecting block 14 and the elastic air guide sheet 13 can be adjusted accordingly according to the amount of water vapor inside the boiling chamber 11, thereby ensuring that the amount of water vapor discharged along the exhaust hole 4 is the heat required for heating and shaping the interventional surgical catheter, further improving the heating and shaping accuracy. When the interventional surgical catheter needs to be shaped, the clamping component 8 drives the corresponding position of the end of the interventional surgical catheter to move downward a certain distance by adjusting the current passed through the electromagnetic ring 9, and cooperates with the increase in the opening amount of the exhaust hole 4 to further improve the shaping accuracy. The shaping efficiency and shaping effect of the interventional surgical catheter are improved, the shaping accuracy is improved, the difficulty and low shaping accuracy of manual shaping are avoided, and the safety protection of medical staff is improved; and when the stirring rod 16 drives the sliding rod 19 to rotate, it not only improves the stirring and evaporation effect of the boiling water inside the boiling chamber 11, but also cooperates with the magnetic attraction effect of the magnetic push block 29 and the ferromagnetic rod 31 to ensure that the sliding rod 19 slides irregularly inside the side groove 17, further improving the irregular stirring effect of the boiling water inside the boiling chamber 11, and at the same time achieving the scraping and cleaning of the inner wall of the boiling chamber 11, avoiding the formation of scale after a long period of boiling of the boiling water, causing pollution of the inner wall of the boiling chamber 11, and then affecting the subsequent heating and shaping of the interventional surgical catheter.

[0075] Third embodiment

[0076] A method for shaping an interventional surgery catheter, the shaping method uses an interventional surgery catheter shaping device to shape the interventional surgery catheter, comprising the following steps:

[0077] S1. Pass the interventional surgery catheter through the clamping assembly 8 in sequence, add boiling water into the boiling chamber 11, and the controller controls the rotating shaft 15 to rotate and drive the stirring rod 16 to rotate and stir.

[0078] S2. When the amount of water vapor increases, the temperature at the end of the heat expansion tube 28 increases, the heated volume of the heat expansion material inside the heat expansion tube 28 increases and drives the elastic connecting block 14 at the end to move in opposite directions, the distance between the two elastic connecting blocks 14 increases, and the amount of water vapor discharged along the exhaust hole 4 increases.

[0079] S3. When the interventional surgical catheter needs to be shaped, the controller controls the electromagnetic ring 9 at the corresponding position to increase the current, the magnetism of the electromagnetic ring 9 increases, and the magnetic attraction force with the magnetic support block 7 increases. The magnetic support block 7 drives the interventional surgical catheter to move downward through the clamping assembly 8, and the piston rod 6 moves downward along the air storage chamber 24. The thermal expansion material inside the air storage chamber 24 reaches the inside of the thermal expansion tube 28 along the transfer chamber 27. The volume of the thermal expansion tube 28 increases and drives the elastic connecting block 14 to continue to move toward the opposite end. The distance between the two elastic connecting blocks 14 continues to increase, and the amount of water vapor discharged along the exhaust hole 4 at this position increases.

[0080] By further limiting the shaping method, the shaping efficiency can be improved and the shaping quality can be guaranteed.

When the amount of water vapor increases, the temperature of the end of the heat expansion tube (28) increases, the heated volume of the heat expansion material inside the heat expansion tube (28) increases, and drives the elastic connection block (14) at the end to move in opposite directions, the distance between the two elastic connection blocks (14) increases, and the amount of water vapor discharged along the exhaust hole (4) increases; S3. When it is necessary to shape the interventional surgical catheter, the controller controls the electromagnetic ring (9) at the corresponding position to increase the current, the magnetism of the electromagnetic ring (9) increases, and the magnetic attraction force with the magnetic support block (7) increases. The magnetic support block (7) drives the interventional surgical catheter to move downward through the clamping assembly (8). The piston rod (6) moves downward along the air storage chamber (24). The thermal expansion material inside the air storage chamber (24) reaches the inside of the thermal expansion tube (28) along the transfer chamber (27). The volume of the thermal expansion tube (28) increases and drives the elastic connection block (14) to continue to move toward the opposite end. The distance between the two elastic connection blocks (14) continues to increase, and the amount of water vapor discharged along the exhaust hole (4) at this position increases.
