Examples
The invention relates to an operation process and a method of a prostate tissue coagulation device for prostate excavation surgery.
1) The front end head 11 of the catheter is inserted from the genital urethral orifice of a patient by holding the catheter 1 by an operating handle 13 of the catheter 1 until the front end head 11 of the catheter extends into a urine discharge port at the prostate part on the lower side of the bladder through the urethra; this process, in conjunction with the ultrasound guidance work, ensures that the catheter tip 11 reaches the desired position under ultrasound guidance monitoring, during which the balloon 2 of the catheter tip 11 is as shown in the state of fig. 3.
2) The air bag 2 is inflated by operating the air charging device 4 through the air delivery pipe 3, so that the air bag 2 is expanded to completely block the urination port at the lower side of the bladder and stops, and the air bag 2 at the front end 11 of the catheter is shown as the state of the attached drawing 2; the process is completed in cooperation with ultrasonic guidance operation, and the airbag 2 is ensured to be expanded to a proper size.
3) The catheter 1 is held by an operating handle 13 of the catheter 1 to slowly pull the catheter 1 back, and when the expanded air bag 2 is clamped at the urine outlet at the lower side of the bladder, the catheter 1 is blocked and cannot be pulled to stop, so that the positioning operation of the catheter 1 is completed. The length of the prostatic urethra of an adult male is generally 5cm, the coagulation tube 5 is just positioned at the position 1cm below the urine discharge port on the lower side of the bladder after positioning, so that the coagulation tube 5 with the length of 3cm is positioned at the central part of the prostatic urethra, the upper part of the coagulation tube 5 is reserved with 1cm of margin from the urine discharge port on the lower side of the bladder, the whole length of the coagulation tube 5 is positioned in the prostatic urethra, and the lower part of the coagulation tube 5 is also reserved with 1cm of margin from the lowest end of the prostatic urethra.
4) The coagulation control device 7 is started to control the operation of the coagulation tube 5, the coagulation tube 5 makes the prostatic urethra to be coagulated and necrotized outwards by taking the coagulation tube 5 as the center, the time of the coagulation operation is controlled to make the prostatic to be necrotized outwards along the center to a certain depth, the coagulation operation can be stopped, and the coagulation control device 7 is immediately closed. The coagulation tube 5 with a specific structure used here is an electric heating tube, a variable frequency controller is adopted as a coagulation control device 7 to control and heat the electric heating tube, so that the temperature of the electric heating tube is raised to 75-100 ℃, prostate tissue around the electric heating tube begins to gradually necrotize outwards under the action of the temperature range, capillary vessels in the necrotic prostate tissue gradually solidify, and the time and the temperature of the electric heating tube are controlled by the variable frequency controller, so that the prostate tissue necrotizes to a certain range along the central position. In the process, the upper limit of the heating temperature is set to be not too high, so that the damage to the whole prostate is avoided, the necrosis range is controlled by controlling the heating time, and the purpose of surgical treatment is met.
5) The inflation device 4 is operated to deflate, so that the air bag 2 is contracted and retracted to the state shown in the figure 3 when the catheter 1 is inserted, and then the catheter 1 is slowly drawn out of the urethra along the urethra by operating the handle 13, so that the necrosis and coagulation operation in a certain range of the central part of the prostate is completed.
6) The central of the prostatic necrosis part is subjected to a range excavating operation by utilizing an excavating operation tool, so that the prostatic urethra is enlarged.
