[0002] Ureteral guide sheath is a commonly used instrument in urological surgery. Its main function is to guide the guide wire and catheter into the ureter for ureteroscopy, stone removal, lithotripsy and other operations. In the prior art, ureteral guide sheaths mostly use manual control of the perfusion fluid flow rate. There are some problems with the prior art: manual control of the perfusion fluid flow rate is difficult to accurately control and can easily cause ureteral damage. Doctors need to pay attention to the perfusion fluid flow rate at all times, which increases the difficulty of surgical operations. The inability to automatically adjust the perfusion fluid flow rate according to the physiological condition of the ureter leads to low surgical efficiency. Therefore, we propose a ureteral guide sheath with an intelligently controlled medical perfusion pump and a preparation method thereof. Summary of the invention
