Endoluminal surgery pressure monitoring system, adjusting system and method

Abstract

The invention discloses an endoluminal surgery pressure monitoring system which comprises a pressure measuring optical fiber and a pressure monitor. The first end, extending into a cavity, of the pressure measuring optical fiber is provided with a pressure sensor, and the second end of the pressure measuring optical fiber is connected to the pressure monitor. The pressure sensor is used for measuring the pressure parameter in the cavity and transmitting the pressure parameter to the pressure monitor to be displayed and analyzed, the pressure parameter in a kidney can be obtained through observation visually and conveniently. The pressure sensor extends into the specified position in the cavity to be monitored, and the accuracy is high. According to an endoluminal surgery pressure adjusting system and method, on the basis of the endoluminal surgery pressure monitoring system, a peristaltic pump connected with a pressure controller is additionally arranged, the monitored pressure is compared with the maximum pressure set on the pressure monitor, opening and closing of the peristaltic pump are controlled according to an analysis and comparison result, so that liquid is poured into or discharged out of the peristaltic pump, pressure in the cavity is kept relatively constant in the endoscopic surgery process, and safe conduction of the surgery can be better achieved.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for medical operations, in particular to an intracavity surgical pressure monitoring system, a regulating system and a method. Background technique [0002] At present, when performing endoscopic surgery in human cavities, such as intracranial and intrarenal endoscopic surgery, the pressure in the cavity is a very important parameter, and if it is not properly controlled, serious complications may occur. Therefore, during endoscopic surgery, the intraluminal pressure is monitored by a pressure measuring device. Taking the kidney as an example, the current pressure measuring devices are all measured in vitro through a pressure sensor at the entrance into the ureteral sheath. Then, according to the thickness and length of the pipe diameter entering the ureter, the pressure value measured by the pressure sensor is converted into the corresponding pressure of the renal perfusate. And there is no p...

without pressure regulator

[0003] However, the existing measurement method has the problem of inaccurate pressure measurement and low precision, specifically:

[0004] 1. The intrarenal pressure obtained through pressure conversion is inaccurate

[0005] 2. The pressure cannot display the current intrarenal pressure in real time, because the measurement point is not in the same place as the actual intrarenal pressure when measured in vitro, so the measured pressure value itself has a large error; and the pressure sensor is dynamic measurement, there is error
