美国Valleylab（威力）公司生产的SSE2L型高频电刀,以它优异的性能价格比赢得了用户。 电刀在单极方式工作时,高频电流的流经路线是机器→手术电极刀→患病组织→电极板→机器,电流在手术电极刀和患病组织接触处产生的热量是手术所需要的。当患者皮肤和电极板之间接触不良时,电流也会在此产生热量而烧伤患者正常皮肤,为此,该机设计了REM接触质量监测电路。当电极板和患者皮肤接触不良时,监测电路发出报警信号,同时切断高频电流输出,避免了烧伤患者的正常皮肤。 电极板是由相互绝缘的两导电垫片构成的,每一垫片引出一根导线和主机相连,使用时两垫片贴在患者皮肤上,机器自动检测两垫片之间的电阻,从而间接测量了电极板和皮肤之间的接触电阻是否合乎要求。该机在使用一段时间后,会出现电极板和患者皮肤接触良好,而监测电路发出报警信号,并切断高频电流的情
The SSE2L high-frequency electric knife produced by Valleylab, USA, has won users with its excellent performance-price ratio. When the electric knife is working in the unipolar mode, the flow path of the high-frequency current is machine→surgical electrode knife→scarred tissue→electrode plate→machine. The heat generated at the contact between the surgical electrode blade and the diseased tissue is required for the operation. of. When the contact between the patient’s skin and the electrode plate is poor, the current will also generate heat and burn the patient’s normal skin. For this reason, the machine is designed with REM contact quality monitoring circuit. When the electrode plate is in poor contact with the patient’s skin, the monitoring circuit issues an alarm signal and cuts off the high-frequency current output to avoid the normal skin of the burned patient. The electrode plate is composed of two conductive gaskets insulated from each other. Each gasket leads out one lead and is connected to the host. When the two gaskets are used, the two gaskets are attached to the skin of the patient, and the machine automatically detects the resistance between the two gaskets, thereby indirectly Measured whether the contact resistance between the electrode plate and the skin is satisfactory. After the machine is used for a period of time, there will be good contact between the electrode plate and the patient’s skin, and the monitoring circuit will send an alarm signal and cut off the high-frequency current.
