Flexible ureteroscope perfusion equipment having air pressure perfusion pump

Abstract

The invention relates to the technical field of auxiliary flexible ureteroscope perfusion equipment, and discloses flexible ureteroscope perfusion equipment having an air pressure perfusion pump. Theperfusion equipment includes infusion water bags; the infusion water bags are connected to a flexible ureteroscope through an infusion tube; the outer sides of the infusion water bags are wrapped withair pressure bags; and the air pressure bags are connected to an air pump with controllable pressure. Through the adopting of an air pressure perfusion mode, the air pressure bags wrapping the infusion water bags can be adopted as pressurized perfusion media, and the air pump can inflate and pressurize the air pressure bags so as to make the pressure of the infusion water bags increased; and dueto the compressibility of gas, the pressure can be stabilized during perfusion, so that excessive instantaneous pressure can be avoided.

Description

technical field [0001] The invention relates to the technical field of auxiliary perfusion equipment for flexible ureteroscopes, in particular to perfusion equipment for flexible ureteroscopes with an air pressure perfusion pump. Background technique [0002] Flexible ureteroscopic surgery is an emerging clinical operation at present. It is mostly used for lithotripsy treatment of ureteral calculi and kidney stones with a diameter less than 2 cm. It is also used for the diagnosis and examination of upper urinary tract tumors. It uses a thin mirror with a diameter of about 3mm to insert the ureter through the urethra and bladder to crush and remove ureteral or kidney stones. At the same time, it can perform microscopic examination of each calyx in the renal pelvis for early detection and diagnosis of tumors in the renal pelvis. [0003] Compared with traditional open surgery and percutaneous nephrolithotomy, flexible ureteroscopic surgery has the advantages of less damage, le...

Problems solved by technology

[0005] Disadvantages of manual water fetching: 1. An additional doctor's assistant is required to perform the operation during the operation, which increases the labor cost

2. When fetching water manually, it is impossible to know the water injection pressure objectively, and there is a risk that the internal pressure of the renal pelvis will be too high due to the high water pumping pressure

[0006] Disadvantages of the traditional percutaneous nephroscopic perfusion pump: 1. The pressurized medium is a mechanical device that directly pressurizes the water. After the water pump reaches the set pressure, although it can feedback to stop the irrigation, the mechanical device will still pressurize the perfusate for a short time due to inertia. Pressurization, resulting in transient high pressure in the renal pelvis
