什么是HF手术?

在高频手术中,与高频相结合的交替电流通过人体进行引导。组织被特异性损坏或切割。与用正常手术刀切割的切割相反,由于受影响的血管可以平等地关闭,因此出血也被母乳喂养。

 

HF手术的应用技术

单极技术

单极技术是最常用的技术。高频电压源的一种极点(中性电极)通过尽可能大的区域连接到患者。手术仪器是另一根杆(活动电极)。电能通过对中性电极最低电阻的路径通过活性电极流动。在活动电极的不久的将来,功率密度最高。热效应是这里最多的。随着距离的平方,电力密度也会降低。为了防止燃烧并保持体内的功率密度,电极应尽可能大。由于中性电极的大面积,下面的皮肤没有明显加热。为了防止燃烧,中性电极的正确定位是决定性的。

 

双极技术

在双极应用技术的情况下,电流仅流过手术过程(切割或凝结)的身体部分。两个孤立的电极直接引导到要操作的区域。 HF电压位于电极之间。该电路在两者之间的织物上关闭。热效应发生在两个电极之间的组织中。与单极技术相反,当前流的路径在这里完全明显。此外,只需要大约20-30%的单极技术性能。周围的组织也保持未损坏,并且患者的测量设备不会受到干扰。双极应用技术在关键,精确的应用中尤其使用。这些包括微型,神经和ENT手术。

 

HF手术的频率范围是多少?

在300 kHz和2000 kHz之间的频率范围内,使用了HF手术。为了防止法拉多(令人不安的肌肉抽搐),频率范围必须超过300 kHz。但是,法拉第的刺激也可能以公司频率出现。因此,电容器(2500 pf)的容量较低。但是,肌肉抽搐不能完全排除。确定2000 kHz的上限是为了避免对患者的伤害燃烧。

 

HF发电机及其工作方式

HF发电机的最大输出为400W。在晶体管外科手术冠军中,振荡器在驱动器级别上控制功率放大器,频率约为700 kHz。在表面凝结的情况下,振荡器用约20 kHz扫描,比为1:5。两个单独的控制器设置了驾驶员级别的工作电压和切割性能。功率放大器具有几个在切换操作方面使用的平行动力性能晶体管。这可以提高效率。功率放大器变压器的二级电路导致通过滤波器电容器连接电极(主动或中性)。中性电极可以直接接地或电容或电动操作。得益于患者保护电路,发电机仅与连接的N.骨电极一起使用。声音警报表明供应线的中断。
