Mobile integrated cavity mirror system with pneumoperitoneum control and electromagnetic suppression functions

Abstract

The invention provides a mobile integrated cavity mirror system with pneumoperitoneum control and electromagnetic suppression functions, which comprises a plurality of functional modules, a central control unit for controlling the operation of the plurality of functional modules and a power supply device for supplying power to the plurality of functional modules. A plurality of functional modulescomprises a pneumoperitoneum apparatus, a man-machine interaction screen, a cold light source and a camera, wherein the pneumoperitoneum apparatus is used for inflating a cavity. The pneumoperitoneumapparatus comprises a proportional control valve, a switch electromagnetic valve, an air release valve, an air flow sensor and an air pressure sensor. The power supply device includes a switching power supply and a plurality of electromagnetic interference suppression circuits. The mobile integrated cavity mirror system with pneumoperitoneum control and electromagnetic suppression functions can solve the problem of video jitter caused by the instantaneous change of the air pressure caused by the opening and closing moment of the switch valve, and avoid the mutual transmission of electromagnetic interference signals among the functional modules.

Description

technical field [0001] The invention relates to the technical field of endoscopic systems, in particular to a mobile integrated endoscopic system with pneumoperitoneum control and electromagnetic suppression functions. Background technique [0002] At present, laparoscopic surgery has become more and more popular, and minimally invasive surgery has become the consensus of surgeons and patients. The laparoscopic system can provide high-definition enlarged surgical images, which can clearly display the fine structure of internal tissues. Compared with traditional open surgery, the field of view is clearer, so the operation is more accurate and fine, and it effectively avoids unnecessary damage to organs other than the surgical site. Interference, and less blood loss during the operation, the operation is safer. [0003] However, the current laparoscopic system has the following disadvantages: [0004] (1) When the intra-abdominal pressure reaches balance, there will be vibra...

Problems solved by technology

However, the electromagnetic interference signals generated by each functional module during work are transmitted to other functional modules through the working power line, resulting in mutual interference between the functional modules, thereby affecting the image quality of the endoscope
