| 摘要 |
An electrosurgical instrument is manufactured by presenting an electrode, and attaching a sacrificial portion to the electrode to form a first electrode assembly. An insulating material is moulded over the first electrode assembly to form a second electrode assembly, and the second electrode assembly is subjected to a further process which is capable of removing the sacrificial portion without removing the insulating material. The sacrificial portion is removed to form at least one cavity within the electrosurgical instrument. |
