腹腔镜现已广泛用于胆囊切除，子宫切除及疝修补等手术。在手术操作中需不断向腹腔内注入生理盐水，以冲洗积血，清晰手术野。因腹腔镜是在人工气腹下（压力约2．4kPa）操作，直接用输液瓶注水压力不够，专用加压装置价格昂贵。我院自行设计了一种加压注水装置，制作简便、操作 Laparoscopy has been widely used for cholecystectomy, hysterectomy and hernia repair. During the operation, physiological saline should be continuously injected into the abdominal cavity to flush the blood and clear the surgical field. Because the laparoscope is operated under the artificial pneumoperitoneum (pressure is about 2.4kPa), the injection pressure of the direct infusion bottle is not enough, and the special pressure device is expensive. Our institute has designed a pressurized water injection device to make it simple and easy to operate.
