超声刀幻灯片.pptVIP

临床优势 无电流通过病人躯体 最小的组织焦痂和干燥 最小热损伤下的精确切割 极少的烟雾 多功能减少器械的更换 刀头的故障排除 1、温度过高（持续工作时间过长，到达100度以上时会自动报警） 在水中浸泡一下，降低温度 2、刀头夹有异物 在水中激发振动一下，或用针把刀头的异物勾出来（湿纱布擦洗也可） 刀头和手柄配件等的消毒 不可高温高压消毒（手柄） 可用2%碱性戊二醛浸泡 可用福尔马林熏 可用环氧乙烷熏 可用低温等离子 超声刀的管理 有条件可以专人管理 可能的话刀头专科专用 刀头和手柄等精细配件需小心消毒，防止摔落和强力碰撞 可以用纱布包裹刀尖和手柄螺丝部分以加强保护 手术中主机摆放离电刀最好超过1M 及时清洗，使用爱惜 临床推广 超声刀主要应用于五官科手术、头颈外科手术、乳腺外科手术、胸外科手术、肝胆外科手术、腹部外科手术、泌尿外科微创手术及微创妇科手术。其中微创妇科手术包括子宫肌瘤切除术、附件切除术、宫外孕输卵管开窗术、子宫全切除术、盆腔淋巴结清扫术等。在妇科手术中超声刀能够安全地关闭淋巴管；其较小的侧向热损伤可以减少输尿管、膀胱或其他粘连脏器的损伤，使处理盆腔粘连更加安全，能够有效地保护卵巢的机能和减少正常卵泡的功能损伤；空洞化效应方便阔韧带前后页和膀胱腹膜返折的打开；5mm血管关闭能力可以安全处理子宫动脉和卵巢固有韧带及其他韧带。 谢谢大家！ * Nomenclature Generator Cart Foot Switch * * Hemostasis is achieved by denaturation of tissue protein and formation of coagulum; these effects occur at the operating tissue temperature of the Harmonic Scalpel - temperatures less than 100oC. The higher temperatures associated with electrosurgery and laser result in tissue dessication and eschar. * The three components of the Harmonic Scalpel System are high-frequency, computer-controlled generator, a hand piece which houses the ultrasonic transducer, and a variety of interchangeable blade configurations. A computer-controlled electrical signal causes the piezo-electric ceramics in the ultrasonic transducer in the Harmonic Scalpel Hand Piece to expand and contract, converting electrical energy to mechanical motion (ultrasound). The transducer, attached to the mount, transmits the ultrasonic vibration to the attached blade. To simplify, the electric signal sent to the transducer in the Harmonic Scalpel Hand Piece is converted to mechanical motion. The result is vibration of 55,500 cycles per second (ultrasonic motion) at the blade tip. * 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 th
