恒压腹腔镜手术辅助系统
Constant Pressure Laparoscopic Surgery Assistant System
摘要
Abstract
With the wide application of laparoscopic surgery in clinical practice,the limitations of electronic pneumoperitone-um machines are gradually exposed:on the one hand,pneumoperitoneum machines will cause pressure shocks in the abdominal cavity while establishing pneumoperitoneum,which will damage some tissues in the body.On the other hand,the stability of the pneumoperitoneum for abdominal pressure control still needs to be improved.Aiming at the stability and flexibility of abdominal pressure control in laparoscopic surgery,a constant pressure laparoscopic surgery assistant system is proposed.This system im-proves the traditional pneumoperitoneum by replacing the multi-stage solenoid valve combination structure with an electric regulat-ing valve,and realizes a gradual flow adjustment.After analyzing the flow characteristics of the valve port and modeling the abdomi-nal cavity,a gradual valve function is obtained,which can close the valve in advance and avoid the overshoot of the abdominal pres-sure caused by the valve lag.Finally,the system ensures the stability of abdominal pressure during the operation under the gradual constant pressure control strategy.Experiments show that the system can work stably under this strategy.关键词
