Intelligent endoscopic system with pneumoperitoneum control and central control module

Abstract

The invention provides an intelligent endoscopic system with a pneumoperitoneum control and central control module. The intelligent endoscopic system comprises an integrated endoscopic system and a processing system. The integrated endoscopic system comprises a plurality of functional modules, a central control unit which controls the operation of the plurality of functional modules and a power supply device which supplies power to the plurality of functional modules. A plurality of functional modules include a pneumoperitoneum for inflating the cavity, a man-machine interactive screen, a cold light source and a camera, the pneumoperitoneum includes a proportional control valve, a switching solenoid valve, a bleed valve, an air flow sensor and a pressure sensor, and a power supply deviceincludes a switching power supply and a plurality of electromagnetic interference suppression circuits.; The processing system is used for dynamic target location. The invention can solve the problemof video jitter caused by the instantaneous change of the air pressure caused by the instantaneous opening and closing of the on-off valve, avoids the electromagnetic interference signals transmittedbetween the functional modules, and effectively improves the "noise" sensitive problem.

Description

technical field [0001] The invention relates to the technical field of endoscopic systems, in particular to an intelligent endoscopic system equipped with pneumoperitoneum control and central control modules. 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) During laparoscopic surgery, due to the noise characteristics of the minimally i...

Problems solved by technology

[0005] (2) When the intra-abdominal pressure reaches balance, there will be vibration at the moment when the switch valve is opened and closed, which will seriously affect the visual effect during the operation;

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
