颅外-颅内动脉吻合治疗脑缺血疾病是近年来国内新开展的手术。手术过程中需用双极电凝机进行微血管止血。这种机器目前国内尚未生产,大多靠进口解决。我院医疗器械修配室,为了配合脑外科开展这一手术,根据临床要求,自力更生,因陋就简,在有关单位支持下,利用旧高频电刀改制成一台双极电凝机。机器长320毫米,宽230毫米,高135毫米。全重3.75公斤。本机由电源、变压器、火花放电器、振荡电路、输出电路和附件(脚踏开关、双极电凝镊)等组成。其基本工作原理是:电源接通后,通过变压器产
Extracranial-intracranial arterial anastomosis in the treatment of cerebral ischemia is a newly developed surgery in recent years. Need to use bipolar coagulation in the process of microvascular hemostasis. This kind of machine is not yet produced in China at present, and most of them are solved by import. Our hospital medical equipment repair room, in order to cooperate with brain surgery to carry out this operation, according to clinical requirements, self-reliance, because of the simple, with the support of the relevant units, the use of the old high-frequency electric knife into a bipolar coagulation machine. The machine is 320 mm long, 230 mm wide and 135 mm high. Full weight 3.75 kg. The machine from the power supply, transformers, spark discharger, oscillation circuit, the output circuit and accessories (foot switch, bipolar coagulation tweezers) and other components. The basic working principle is: power is turned on, through the transformer production
