Endoscope perfusion system for non-contact monitoring of intrarenal pressure

Abstract

The invention provides an endoscope perfusion system for non-contact monitoring of intrarenal pressure, wherein the endoscope perfusion system comprises a perfusion execution mechanism and a perfusioncontrol unit; the perfusion execution mechanism comprises a liquid injection device and a force sensor; the liquid injection device is used for completing liquid injection, and the force sensor is used for measuring an acting force value of the liquid injection device in a liquid injection process; the perfusion control unit is used for calculating the acting force value measured by the force sensor to obtain an intrarenal pressure value. The non-contact intrarenal pressure monitoring function can be achieved, due to the fact that the non-contact intrarenal pressure monitoring device does notmake contact with the human body, safety is better, disinfection and sterilization are more convenient, cost saving is facilitated, and burdens of hospitals and patients are relieved.

Description

technical field [0001] The invention relates to an endoscope perfusion system in the technical field of medical devices, in particular to an endoscope perfusion system for non-contact monitoring of intrarenal pressure during operation. Background technique [0002] Transureteroscopic intrarenal interventional surgery plays an important role in the diagnosis and treatment of urinary stones and upper urinary tract diseases. When using a flexible ureteroscope for surgery, it is necessary to continuously inject water into the endoscope channel to clean the lens to ensure a clear view during the operation. This operation is called perfusion. [0003] Perfusion causes an increase in intrarenal pressure. Excessive intrarenal pressure can lead to complications, such as infection, which can lead to germs entering the human blood system in severe cases, causing sepsis and threatening the lives of patients. Therefore, in order to avoid excessive intrarenal pressure, it is very import...

AI Technical Summary

Problems solved by technology

However, the pressure-measuring optical fiber occupies a certain space in the endoscope channel, which is not conducive to the entry and operation of other surgical instruments, and also reduces the perfusion flow rate.

[0007] In addition, the pressure sensors used in the above two published patents are in direct contact with the human body, which poses safety risks and poses challenges to disinfection and sterilization, increasing surgical risks and hospital burdens; if disposable pressure sensors are used, it will increase the number of operations cost, increasing patient burden
