1.安装超声刀刀头时，不能使用暴力，必须用专用扭力扳手将其卡紧。 听到两次“咔、咔”声为宜。
1. When installing the ultrasonic cutter head, do not use violence, but clamp it with a special torque wrench. It is advisable to hear "click, click" twice.
否则会导致：①手柄螺钉折断 ②管腔卡口变形
Otherwise, it will lead to: ① broken handle screw ② deformation of lumen bayonet
2.拿取和使用时，应避免重压或掉落。轻拿轻放！
2. When taking and using, avoid heavy pressure or falling. handle gently!
否则会导致：①刀具变形 ②输出功率偏差
Otherwise, it will cause: ① tool deformation ② output power deviation
3.测试时，钳口必须张开，并将刀头暴露在空气中或水中。确保刀芯周围无障碍。
3. During the test, the jaw must be open and the cutter head must be exposed to air or water. Make sure there are no obstacles around the core.
否则会导致：①刀芯断裂 ②损伤钳口镶片
Otherwise, it will cause: ① breakage of the cutter core ② damage to the jaw insert

4.测试和使用过程中，不允许触摸刀头；不允许触碰金属、骨骼等硬性物质；不允许钳口在没有钳夹组织时激发输出；工作时不允许旋转刀头。
4. Do not touch the cutter head during testing and use; Do not touch metal, bone and other hard substances; The jaw is not allowed to stimulate the output when there is no clamp tissue; It is not allowed to rotate the cutter head during operation.
确的操作和使用是延长刀具寿命的关键，否则，对刀头的损坏是极大的。
Correct operation and use is the key to prolong the tool life, otherwise, the damage to the tool head is great.
否则会导致：①灼伤身体触摸部位 ②刀芯断裂 ③损伤钳口镶片
Otherwise, it will cause: ① burn the touch part of the body ② fracture of the cutter core ③ damage to the jaw insert
5.钳口咬住组织后，不可以向上挑或向下压，应将在钳夹组织后顺着往后方拉紧，保持一定的张力。组织夹持在钳口的2/3部位为宜，组织游离好后再夹持，不要夹持太大块组织。
5. After the jaw catches the tissue, it shall not be lifted up or pressed down. It shall be tightened along the back after clamping the tissue to maintain a certain tension. The tissue should be clamped at 2 / 3 of the jaw, and then clamped after the tissue is free. Do not clamp too large tissue.
否则会导致：①刀芯断裂 ②输出功率偏差 ③转向轮损坏
Otherwise, it will cause: ① breakage of cutter core ② deviation of output power ③ damage of steering wheel
6.使用持续工作时间不应超过10秒，一般7秒就要断开，再二次工作；每隔10～15分钟应把刀头浸在水中，激发输出并轻轻抖动，把刀头里的组织和血块冲出，以免堵塞。
6. The continuous working time shall not exceed 10 seconds. Generally, it shall be disconnected in 7 seconds and work again; Immerse the knife head in water every 10 ~ 15 minutes, stimulate the output and shake gently, and flush out the tissue and blood clot in the knife head to avoid blockage.
持续工作时间超过10秒对刀头的损害是的。
The damage to the cutter head caused by continuous operation for more than 10 seconds is.
否则会导致：①损伤刀芯和镶片 ②管腔堵塞 ③输出功率偏差
Otherwise, it will cause: ① damage to the cutter core and insert ② lumen blockage ③ output power deviation
