Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a urinary calculus lithotripsy system and an operation method. Background Art

[0002] The urinary system is one of the important excretory systems of the human body. It consists of two kidneys, ureters connecting the two kidneys to the bladder, the bladder, and the urethra that communicates with the outside of the body. Its main function is to produce and excrete urine, excrete metabolic waste from the body in the form of urine, and at the same time regulate water and salt metabolism and acid-base balance to maintain the stability of the body's internal environment.

[0003] Drinking too little water, having bad eating habits, and the geographical environment and climate in which people live can all lead to urinary stones. One of the most notable symptoms of urinary stones is severe pain. When stones move in the urinary tract, especially when they go down in the ureter, they will irritate the urinary tract mucosa and cause severe pain in the abdomen or lower back. Urinary stones are often accompanied by urinary tract infections, especially when stones cause urinary tract obstruction. Infection is more likely to occur. Urinary tract infections not only lead to bladder irritation symptoms such as frequent urination, urgency, and pain, but also cause serious complications such as pyelonephritis, pyonephrosis, and perinephritis. Urinary stones need to be treated.

[0004] Existing treatments for urinary stones include conservative treatment, drug treatment, extracorporeal shock wave lithotripsy, endoscopic lithotripsy, laser lithotripsy and surgical treatment, among which laser energy is used to break up the stones and then excrete them with urine. Laser lithotripsy is suitable for various types of urinary stones and has a faster recovery after surgery. However, when existing urinary stones are treated with laser lithotripsy, one end of the optical fiber is inserted into the human urethra, thereby entering the human urinary system for laser lithotripsy treatment, but the following problems may arise: First, when treating softer stones, using the minimum frequency laser may cause unnecessary damage to the surrounding mucosal tissue due to excessive laser energy. Secondly, when treating harder stones, even if the laser frequency has reached the maximum, the ideal lithotripsy effect cannot be achieved due to the excessive hardness of the stones, causing inconvenience in actual use.

[0005] Therefore, it is necessary to provide a new urinary stone lithotripsy system and operation method to solve the above technical problems. Summary of the invention

If the stone is soft and the minimum frequency laser may still cause damage to the human mucosa, widening the size of the parabolic opening can reduce the focusing intensity of the laser, and can effectively crush the stone without damaging the human mucosa. Moreover, widening the parabolic opening allows the laser beam to diffuse before reaching the stone, thereby reducing the energy density per unit area and reducing the risk of damage. If the stone is hard and the laser frequency has reached the maximum but still cannot achieve the stone crushing effect, narrowing the size of the parabolic opening can enhance the focusing intensity of the laser beam, and the laser energy can reach a higher density in a smaller area, thereby improving the stone crushing efficiency. The present invention solves the problems that the laser energy with the minimum frequency still causes damage to the surrounding mucosal tissue when crushing the soft stone and the laser energy with the highest frequency still cannot achieve the stone crushing effect. The present invention has the advantages of good use effect and high applicability.

[0026] 2. When the present invention is in use, marking lines are provided on the surfaces of the three adjustment plates, and the marking lines include scale one, scale two, scale three and scale four for adjusting the opening size of the parabola. By observing the position of the top end of the adjustment component at the marking line, the opening size of the parabola on the surface of the focusing cavity can be determined, so that when the laser frequency is constant, the focusing intensity of the laser can be adjusted. The present invention is suitable for urinary stones of various types and hardness, and has the advantages of high applicability and good use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] S2. Adjusting the laser assembly: After the pre-cooling is completed, observe the marking line 461 on the adjustment plate 46 on the top of the holmium laser body 3, and adjust the position of the rubber ring 37 by rotating the rotating rod 45 according to the position and size of the stone, thereby changing the size of the parabolic opening 361 of the focusing cavity 36, so that the laser beam can be accurately focused on the stone;

[0084] It should be noted that during the adjustment process, attention should be paid to maintaining the combination of the insert block 371 of the rubber ring 37 and the slot 372, as well as the magnetic attraction between the magnet 1 411 and the slot 421, so as to ensure the stability of the adjustment.

[0085] S3, setting laser parameters: during the focusing process, enter the laser setting menu through the display screen 6 on the top of the bracket 1, and adjust the laser frequency, power and other lithotripsy parameters according to the type and size of the stone;

[0086] S4, lithotripsy: After the lithotripsy parameters of the laser are adjusted, the optical fiber 33 is connected to the SMA905 connector 31 through the optical fiber interface 32, the laser mechanism is started, the laser beam is transmitted to the stone position through the optical fiber 33, and the lithotripsy operation is started. During the lithotripsy process, if the lowest frequency laser pulse still causes damage to the human mucosa, the adjustment component is turned according to the scale on the adjustment plate 46 to widen the size of the parabola opening 361. If the highest frequency laser pulse still cannot achieve the lithotripsy effect, the adjustment component is turned to reduce the parabola opening 361.

[0087] S5. End of operation and equipment maintenance: After the stone crushing is completed, first turn off the power supply 5 of the laser mechanism, then disconnect the optical fiber 33, turn off the water pump 22 and the valve 211, clean the stains and residues on the surface of the bracket 1 and the holmium laser body 3, and regularly check the working status of the optical fiber assembly, adjustment assembly, power supply 5 and refrigeration mechanism. If there is any abnormality, repair or replace it in time.

[0088] For the above operation method, there is the following overall system operation process:

[0089] S1: Preoperative preparation and equipment inspection: First, comprehensively assess the patient's physical condition, determine the size, location and number of stones through testing instruments, and preliminarily adjust the parabolic opening size of the focusing cavity according to the texture and hardness of the stones;

[0090] S2: Anesthesia and positioning: After the preparation and examination phases are completed, the appropriate anesthesia method is selected according to the patient's specific conditions and surgical methods, and the location of the stone is re-determined by C-arm X-ray and B-ultrasound;

[0091] S3: Laser lithotripsy: After positioning is completed, one end of the optical fiber assembly is inserted into the urinary system through the urethra until it reaches the location of the stone. The power is turned on to start the laser mechanism to emit high-energy laser pulses. The laser energy is focused on the stone to perform lithotripsy. If the lowest frequency laser pulse still causes damage to the human mucosa, the adjustment component is turned according to the scale on the adjustment plate to widen the parabola opening. If the highest frequency laser pulse still cannot achieve the lithotripsy effect, the adjustment component is turned to reduce the parabola opening.

[0092] S4: Postoperative treatment and observation: After the lithotripsy is completed, turn off the equipment and observe the patient again, including the patient's urination and whether there are large stones in the patient's body, observe the patient's urine color and volume after surgery, and guide the patient's diet and rest.

[0093] It should be noted that when in use, an adjustment component is set up, and the adjustment component is twisted to reduce or widen the size of the parabolic opening 361 on the surface of the focusing cavity 36. If the stone is soft and the minimum frequency laser may still cause damage to the human mucosa, widening the size of the parabolic opening 361 can reduce the focusing intensity of the laser, and can effectively crush the stone without damaging the human mucosa. In addition, widening the parabolic opening 361 allows the laser beam to diffuse before reaching the stone, thereby reducing the energy density per unit area and reducing the risk of injury. If the stone is hard and the laser frequency has reached the maximum but still cannot achieve the stone crushing effect, reducing the size of the parabolic opening 361 of the focusing cavity 36 can enhance the focusing intensity of the laser beam, and the laser energy can reach a higher density in a smaller area, thereby improving the stone crushing efficiency.
