Description

Technical Field

[0001] The invention relates to the technical field of ureteral stent tubes, in particular to a disposable suction-type ureteral stent tube set. Background Art

[0002] The ureteral stent is a hollow tube made of polymer materials. The ureteral stent is widely used in urological surgery. Conventional retention can help urine drain from the kidney to the bladder, avoid the occurrence of stenosis and urinary fistula, and help the discharge of stone fragments. The Chinese patent application number 202210592112.5 discloses a "disposable suction ureteral stent set, including a ureteral stent, a booster tube, a guide wire and a tube removal. The ureteral stent is inserted into the booster tube, and the guide wire passes through the booster tube and penetrates the ureteral stent. One end of the tube removal is connected to a magnetic suction end that cooperates with the proximal end of the ureteral stent. Beneficial effects of the present invention: The present invention uses stainless steel material at the proximal end of the ureteral stent, which is non-magnetic, avoids the harm of magnetic radiation to the human body, and reduces biological risks. A magnetic end is provided at the tube removal. The magnetic end uses a neodymium iron boron magnet to attract the proximal end of the ureteral stent to remove the ureteral stent."

[0003] The existing technology only solves the problem that the proximal end and the extubation head of the stent tube on the market are both magnetic. Since the stent tube is placed in the human body, although the extubation operation can be performed, the magnetic material is easy to cause damage to the human body when the ureteral stent is implanted in the human body for a long time. However, during the one-time use, the tube body is directly extended into the human body. Since the outside of the tube body is in a dry state when extended into the human body, the friction force when extending into the human body will increase. In addition, there is a temperature difference between the temperature of the surface of the tube body and the temperature of the patient's body, which will cause discomfort to the patient and affect the efficiency of the patient's treatment process. If the friction is too large, it may even cause secondary damage to the patient. Summary of the invention

In this way, when the constant temperature base 201 is installed, the fixed mounting block 14 is fitted and docked with the inside of the fixed fitting opening, which increases the firmness of the constant temperature base 2 when it is fixed and prevents deviation during use.

[0040] An inner tube 17 is movably installed in the inner cavity of the bracket tube 5, and a mounting ring 16 is provided around the inner cavity of the bracket tube 5.

Fixed hook blocks are installed by welding at the relative positions of the fixed openings 18 around the right side of the working frame 1, and the fixed hook blocks are L-shaped structures. In this way, the bracket tube 5 is wound and placed by the placement hook rod 11, and the toughness of the bracket tube 5 during use is increased by the elastic reinforcing ribs 15.

[0041] Working principle: During use, the present invention adds lubricant to the inside of the working frame 1, and starts the resistance heating tube 204 to heat the liquid in the inner cavity of the thermal conduction slot 205, and the lubricant in the working frame 1 is heated by the heated liquid, and the temperature controller 202 monitors the problem of the liquid in the thermal conduction slot 205 in real time to avoid the liquid temperature in the thermal conduction slot 205 being too high, which affects the heating of the lubricant in the working frame 1, and at the same time starts the single-phase motor 401 to drive the rotating rod 402 on the rear side to rotate, which will drive the rotating wheel 403 on the rear side to rotate. Since a transmission belt 405 is installed between the rotating wheels 403 on the front and rear sides, when the rotating wheel 403 on the rear side rotates, it will drive the rotating wheel 403 on the front side to rotate, and then the rotating rods 402 on the front and rear sides will rotate at the same time, and at the same time drive the fan blade heads 404 on the front and rear sides. When it rotates, the lubricant added to the inside of the working frame 1 will be stirred and mixed, the efficiency of lubricant heating will be accelerated, and dead corners will be avoided during the heating process of the lubricant, resulting in uneven heating of the mixed lubricant. When the bracket tube 5 is in use, the bracket tube 5 is moved to the inside of the guide tube 12. When the bracket tube 5 moves inside the guide tube 12, the bracket tube 5 will pass through the contact groove 13, and the lubricant inside the working frame 1 will contact the outside of the bracket tube 5 through the contact groove 13. The right end of the bracket tube 5 will move to the right side of the outside of the working frame 1 through the guide tube 12, and the bracket tube 5 will be extended into the human body. After lubrication and heating, the bracket tube 5 can be extended into the human body to make it feel comfortable and reduce the discomfort of extending into the human body. If the temperature is too low and it is directly extended into the body, it will easily cause discomfort to the human body.
