Description

A flexible ureteroscope perfusion equipment with pneumatic perfusion pump

technical field

The utility model relates to the technical field of auxiliary perfusion equipment for a flexible ureteroscope, in particular to a perfusion device for a flexible ureteroscope with a pneumatic perfusion pump.

Background technique

Flexible ureteroscopic surgery is a new surgical operation in clinical practice. It is mostly used for lithotripsy treatment of ureteral stones and kidney stones with a diameter of 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, which is inserted into the ureter through the urethra and bladder, and the ureteral stones or kidney stones are crushed and taken out.

Compared with traditional open surgery and percutaneous nephrolithotomy, flexible ureteroscopic surgery has the advantages of less damage, less pain, and faster recovery for kidney stones less than 2 cm in diameter. You can usually be discharged from the hospital one day after surgery, and outpatient day surgery is available in some hospitals. Kidney stones are one of the high incidence diseases in urology. With the popularization of medical insurance and the improvement of national health awareness, the proportion of patients with kidney stones less than 2 cm is increasing year by year, and the clinical application of flexible ureteroscopy will also increase. more and more common.

In ureteroscopic lithotripsy, water injection is required to balance the renal pelvis pressure, and the water injection operation can also provide a clear vision for the operation and facilitate precise operation. However, there is currently no perfusion device designed for the characteristics of flexible ureteroscopic surgery. Therefore, clinically, when performing flexible ureteroscopic surgery, assistants use a syringe to manually draw water or use a perfusion pump used in traditional percutaneous nephroscopic surgery.

There are 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 artificially pumping water, it is impossible to objectively understand the water injection pressure, and there is a risk of excessively high pressure in the renal pelvis due to excessive water pumping pressure.

Disadvantages of the traditional percutaneous nephroscopic perfusion pump: 1. The pressurizing medium is a mechanical device that directly pressurizes the water. After the 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. Pressurized, resulting in transiently high pressure in the renal pelvis.

In the process of lithotripsy, the consequence of excessive intrapelvic pressure is to increase the risk of infection and lead to sepsis in severe cases. Therefore, clinically, the incidence of sepsis complications after flexible ureteroscopic surgery is significantly higher than that of open surgery and percutaneous nephroscopic surgery. .
