Description
Technical Field
The utility model relates to a ureter endoscope leading-in sheath and automatic accuse pressure adsorption stone removing equipment.
Background
Ureteroscope calculus removing operation is that a ureteroscope enters a ureter from a urethra through a bladder, calculus is removed by using a stone-covering basket or a calculus removing forceps, or accurate calculus is removed under the guide of the ureteroscope through a pneumatic ballistic calculus-removing machine, a laser calculus-removing machine, an ultrasonic ballistic calculus-removing machine and other calculus-removing equipment under the ureteroscope, and the calculus is removed after being crushed. Ureteroscopes are divided into rigid ureteroscopes and soft ureteroscopes. The flexible ureteroscope can reach the upper section of a ureter and even a kidney, and can treat the upper section of urinary calculus easily without operation. The hard ureteroscope is simple and convenient to operate, safe and noninvasive, greatly relieves the pain of a patient, reduces the occurrence of complications and thoroughly removes stones for stones at the middle and lower segments of the ureter.
The ureter soft lens enters the ureter and the kidney through a natural channel of a human urinary system, and is matched with advanced stone/lithotripsy equipment to take out urinary calculus, so that the kidney is protected from leaving any wound on the body surface of a patient during operation. The ureter soft lens used in the operation is fine and soft, the lens can be rotated and bent for 180 degrees, and the ureter soft lens enters small pieces of the renal pelvis in a retrograde manner, so that the calculus can be quickly and accurately found, and the operation visual field is wide and clear.
