Objective:To design and develop a portably minimally invasive diagnostic and therapeutic device for abdominally warfare trauma,which aimed at a scene of rescue environment at frontline,and its feasibility was evaluated preliminarily through animal experiment.Methods:Based on the actual demands of the rescue environment at frontline,a set of portably minimally invasive diagnostic and therapeutic device for abdominally warfare trauma(abbreviation:minimally invasive diagnostic and therapeutic device)was researched,developed and assembled,which included portably integrated host,disposable flexible lens of endoscope,disposable apparatus of minimally invasive surgery,extendable channel device of avoiding pneumoperitoneum and so on.A male Bama miniature pig was selected,and it received two different surgeries included portably minimally invasive diagnostic and therapeutic device,and conventionally laparoscopic surgery after it received general anesthesia.The damage controls included hemostasis of intraoperative parenchyma organ,sealing and repairing of gastrointestinal perforation and drainage of indwelling catheter in abdominal and pelvic cavity between two groups were compared,and the difference of the mobility performance between them also was compared.The operational evaluation of minimally invasive surgery of damage control surgery and the potential of its clinical conversion were conducted.Results:Compared to conventional laparoscopy,this minimally invasive diagnostic and therapeutic device had better mobility,and the transfer time of this device was(3.3±1.0)min,which was significantly shorter than(14.5±3.2)min of conventional laparoscopy,and the difference of that between two device was significant(t=-5.786,P<0.05).The minimally invasive diagnostic and therapeutic device could successfully realize a series of operation of damage control surgery included exploration,flushing,suction,hemostasis,repair and drainage under the pneumoperitoneum or without pneumoperitoneum,which operation was safety and feasibility.Conclusion:The portably minimally invasive diagnostic and therapeutic device for abdominally warfare trauma can realize integration and optimization,and mobility and portability on the basis of the current laparoscopic platform,which can successfully realize the operation of damage control surgery.It has favorable application prospects and capabilities of clinical conversion.
