The cart provides a push/pull handle, a literature storage rack on the back panel, a cord management system, and a rubber mat on the base for foot switch storage. A tie-down strap is supplied for optional use to further secure the generator when transporting over cords, thresholds, or in case the system is bumped into a wall or door. The generator is activated by depressing a simple foot switch to deliver either full power or a preselected variable power level. Variable power levels range from one to five. The variable power level can be preset at the preferred level of cutting. * The blade vibrates longitudinally at 55,500 Hz per second. The blade travels from 50 to 100 microns per stroke. * The Harmonic Scalpel blade vibrates longitudinally at 55,500 Hz per second. The blade travels from 50 to 100 microns per stroke. Rapid acceleration of tissues moving with the blade breaks the hydrogen bonds that give protein structure, which results in a protein coagulum that seals coapted vessels. Deep coagulation of large vessels results when the effect is prolonged. * * * Five (5) factors affecting cutting coagulation: Power level (1-5) Tissue Tension Grip Force Blade sharpness Time  减少手术中更换器械的时间 切割 止血 分离 抓持  整个咬口工作平均 大口切割也不会报警 刀片及宇航才质垫片对热量的耐受 咬合压力 的控制 长时间的空咬激发 容易损伤垫片！ 豪韵超声刀应用科室及术式 普外科：腔镜开放胃肠、肝胆胰脾手术等 胸外科：腔镜开放食管手术、肺手术等 妇 科：腔镜开放子宫切手术等 泌尿外科：腔镜开放膀胱、肾手术等 乳腺外科：乳腺癌根治术等 甲状腺科：腔镜开放甲状腺手术等 耳鼻喉科：开放腮腺手术 ……… 超声刀能做什么？ 切割 止血 抓持、精细游离 精细游离 超声刀和电能手术系统比较 在猪肝脏上切割比较 单极电刀 50 watts Blend 豪韵TM Hook Blade (Level 5) 强生超声刀和双极电刀的热损伤 作用机理 组织效应 潜在不良反应 豪韵超声刀系统介绍 Harmonic---豪韵数码切割止血系统 主机－－－GEN04 手柄－－－HP054 脚踏－－－FSW0
