Description
Technical Field
The invention relates to the technical field of auxiliary ureteroscope filling equipment, in particular to ureteroscope soft lens filling equipment with an air pressure filling pump.
Background
The ureter soft lens operation is an emerging operation in clinic at present, is mainly used for treating ureteral calculus, kidney calculus with the diameter less than 2cm and other broken stones, and is also used for diagnosis and examination of upper urinary tract tumors. A thin mirror with the diameter of about 3mm is inserted into a ureter through a urethra and a bladder, ureteral calculus or kidney calculus is crushed and taken out, meanwhile, each cup in the renal pelvis can be subjected to microscopic examination, and tumors in the renal pelvis can be discovered and diagnosed at an early stage.
Compared with the traditional open operation and the percutaneous nephrolithotomy, the ureter soft lens operation has the advantages of small damage, light pain, quick recovery and the like for nephrolithiasis with the diameter less than 2 cm. The patient can be discharged from the hospital after the operation for 1 day, and the operation can be performed in an outpatient day in some hospitals. The kidney stone is one of the high-incidence diseases of the urinary surgery, along with the popularization of medical insurance, the health consciousness of the whole people is improved, the proportion of the kidney stone patients smaller than 2cm in the kidney stone patients is increased year by year, and the application of the ureter soft lens operation in clinic is more and more common.
Water injection operation is needed to balance the pressure of the renal pelvis in the ureteroscope calculus removing operation, and the water injection operation can also provide a clear visual field for the operation so as to facilitate accurate operation. But at present, no perfusion device designed aiming at the characteristics of the ureter soft lens operation exists. Therefore, clinically, in the ureteroscope operation, an assistant often uses a syringe to manually pump water or a perfusion pump used in the conventional percutaneous nephroscope operation.
The manual water fetching has the defects that: 1. when in operation, a doctor assistant is required to be equipped for the operation, which increases the labor cost. 2. When water is pumped manually, the water injection pressure cannot be known objectively, and the risk of overhigh internal pressure of the renal pelvis caused by overhigh water pumping pressure exists.
The traditional percutaneous nephroscope perfusion pump has the defects that: 1. the pressurizing medium is a mechanical device for directly pressurizing water, and after the water pump reaches the set pressure, although the irrigation can be stopped by feedback, the mechanical device can still pressurize the perfusion fluid for a short time due to inertia, so that the internal pressure of the renal pelvis is overhigh instantaneously.
During lithotripsy, the consequence of over-high pressure in the renal pelvis is increased infection risk, and sepsis is caused in severe cases, so that clinically, the incidence rate of sepsis complications after soft ureteroscopy surgery is obviously higher than that of open surgery and percutaneous nephroscope surgery.
