Background
At present, the pressure in the organ cavity of the organ in the operation is safe when the clinical surgical endoscope minimally invasive intracavity treatment is concerned, medical perfusion equipment at home and abroad only has two parameter settings of perfusion driving pressure and flow, and an operator manually regulates and controls the pressure and the flow according to clinical experience, so that the operator has larger randomness and uncertainty, and the operation experience is less or the operator at first study is not easy to master. Over-high perfusion pressure can cause the opening of the venous valve, the return of the liquid in the cavity into the blood, water absorption and iatrogenic water poisoning.

The temperature of the perfusion liquid in the operation is usually ignored by doctors, and the temperature of the perfusion liquid is continuously raised by the generated heat energy in the using process of energy equipment such as electrosurgery, laser and the like, and when the temperature of the liquid is continuously accumulated to a certain degree, tissues can be burnt, so that heat injury, postoperative stenosis and other related medical accidents occur. Scholars at home and abroad pay attention to the operation formulas of soft ureteroscope lithotripsy, hard ureteroscope lithotripsy, percutaneous nephroscope lithotripsy, hysteroscopy and treatment, choledochoscope lithotripsy, third ventricular fistulization and the like, and the high pressure in the organ cavity in the operation causes great harm, but no good monitoring and solving method exists so far, and the monitoring of the temperature is often ignored by scholars at home and abroad. In view of the above, there is a need to improve upon the prior art.

starting a perfusion pump, perfusing liquid into the cavity of the patient through a channel in the endoscope, collecting the pressure of a pressure sensor by a pressure collection module, transmitting pressure data to a digital centralized control central processing unit, controlling the perfusion pump to stop perfusing the liquid into the cavity of the patient by the digital centralized control central processing unit when the pressure reaches the pressure preset by the digital centralized control central processing unit, and recovering perfusion when the pressure is lower than a preset value;
the temperature in the cavity of the patient is sensed through a guide wire serving as a temperature sensor probe or a temperature and pressure measuring guide sheath head end, and data are transmitted to a digital central processing unit through a temperature acquisition module;
when the medical endoscope is used for treatment, the temperature of the perfusion liquid in the cavity of a patient is continuously raised by the generated heat energy in the process of matching with energy equipment, at the moment, the digital centralized control central processing unit controls the perfusion pump to accelerate perfusion, and simultaneously controls the medical negative pressure aspirator to quickly suck out the perfusion liquid, so that the heat accumulated in the cavity of the patient is taken away in time and the focus tissues flushed out by the liquid are taken away;
the digital centralized control central processing unit draws a pressure curve, a temperature curve, a corresponding time, an average pressure, a cavity temperature alarm setting line, a cavity pressure alarm setting line, total overpressure time, an overpressure mark, an overtemperature mark, an overtreatment alarm pressure limiting feedback alarm prompt in continuous unit time and ultra-average pressure setting feedback alarm prompt data into a chart through a data recording and drawing unit to be displayed on a display for a doctor to observe, review, evaluate, store and print after a surgery.
