文档介绍:双极电凝钳

第一页,共54页
Select Your Energy 选择适合您的能量
第二页,共54页
What to Achieve with Coagulation? 以什么来实现电凝呢?
Hemostasis (Haemostasis)
止血
Greek: heme, blood + stasis, halt = halt of the blood.
希腊语:血红素,血液+凝固,停止=止血
第三页,共54页
Energy-Based Techniques To Ensure Hemostasis & Limit Damage During Laparoscopy 以能量为基础的技术在腹腔镜检查中确保止血和减少伤害
Incomplete hemostasis or incision of an active vascular core can occur even with ideal application
即使操作理想,也会发生不完全的止血或者切开活动的核心血管
Hemostasis during laparoscopy: 用于腹腔镜检查术中的止血:
monopolar electrosurgery 单极电刀
bipolar electrosurgery 双极电刀
ultrasonic energy 超声刀
Etc. 等等
第四页,共54页
Protocol To Minimize Risk 医疗方案:将风险降到最低
The art of surgical hemostasis: 外科止血的艺术:
To prevent vascular trauma with least-possible collateral tissue damage.
保护血管的创伤和最少可能减少附带组织的损害
When bleeding is encountered, the surgeon’s ability to attain hemostasis using a particular modality depends largely on how well he or she understands its technical aspects.
当遇到出血的情况,外科医生能使用一种特殊模式来止血,这很大程度取决于他/她对这器械的技术问题了解程度。

Bipolar Electrosurgery 双极电刀
Mechanism of action 作用机理
Bipolar electrosurgery consolidates an active electrode and return electrode into an instrument with 2 small poles.
双极电刀巩固一个活跃的电极和返回电极到一个有2个小极的器械
These poles can be the tines of a forceps, blades of a scissors, or an electrode matched to a more proximal conductive collar separated by an insulator.
这两极可能是一个钳的尖叉、剪刀的刀片、或是一个电极匹配到更近的导电圈由绝缘体隔开。
The output typically used is the low-voltage “cut” current.
通常用于输出的是低电压“切割”电流。

Bipolar Electrosurgery 双极电刀
Advantages of bipolar energy 双极电流能量的优点
Localization of current between the poles offers distinct advantages. Thermal damage is generally limited to a discrete volume of tissue.
两极之间的局部电流具有明显的优势。热损伤一般仅限于离散量的组织。
A bipolar forceps can be used to coapt and thermally weld blood vessels.
双极抓钳可用来电凝和热焊接血管。
The concentrated current and small distance between the poles also make it possible to desiccate tissue that is immersed in fluid.
