The invention relates to a pneumoperitoneum control system, in particular to a pneumoperitoneum control device and method for endoscopic surgery. The problems that a traditional pneumoperitoneum control system is slow in pneumoperitoneum reconstruction response speed and long in pneumoperitoneum reconstruction time are solved. The pneumoperitoneum control device for endoscopic surgery comprises aninflation control air path and an aspirator; the inflation control air path comprises an inflation air source, an inflation pipe I, an electric pressure reducing valve, an inflation pipe II, an inflation pipe III, an inflation pipe IV and an inflation pressure sensor; the aspirator comprises a suction pipe I, a manual valve, a suction pipe II, a negative pressure machine, a suction pressure sensor I and a suction pressure sensor II; the inflation air source is communicated with the inlet end of a valve body of the electric pressure reducing valve through the inflation pipe I; the outlet end of the valve body of the electric pressure reducing valve is communicated with the inlet end of the inflation pipe IV through the inflation pipe II and the inflation pipe III in sequence. The device issuitable for endoscopic surgery.
Description
technical field [0001] The invention relates to a pneumoperitoneum control system, in particular to a pneumoperitoneum control device and method for laparoscopic surgery. Background technique [0002] Laparoscopic surgery has been rapidly promoted due to its small trauma and fast postoperative recovery, and has been widely used in general surgery and urology. Stable pneumoperitoneum pressure is the prerequisite and important guarantee for the smooth progress of laparoscopic surgery. In the process of laparoscopic surgery, in order to clean up the wound bleeding and exudate, it is necessary to use a suction device for negative pressure suction. Visual field and operating space become poor. In order to ensure that the operation continues smoothly, it is necessary to use the pneumoperitoneum control system for pneumoperitoneum reconstruction (re-inflate the pneumoperitoneum to maintain the pneumoperitoneum pressure within a certain range). However, practice has shown that th...
