电外科器械和系统
摘要：
一种手持式电外科器械包括手持件(2)和电极组件(3)，该电极组件包括连接器(8)、(9)和一个或多个电极(12)、(13)，电极组件(3)通过该连接器能够相对于手持件(2)拆装。手持件包括电池(4)、用于生成射频输出的RF振荡电路(5)、以及可由电外科器械的使用者操作的开关装置(7)。设有控制电路(6)以控制RF输出，该控制电路(6)能够从开关装置(7)接收信号，并响应于该信号而使一个或多个RF输出被提供给电极组件(3)。电极组件(3)包括能够更改到达一个或多个电极(12)、(13)的RF输出的部件(14)、(21)，以便在所述一个或多个电极处产生期望的RF输出。
摘要（英）：

A handheld electrosurgical instrument includes a handpiece (2) and an electrode assembly (3), the electrode assembly including one or more electrodes (12), (13) and a connector (8), (9) by which the electrode assembly (3) is capable of being attached and detached with respect to the handpiece (2). The handpiece includes a battery (4), an RF oscillator circuit (5) for generating a radio frequency output, and switching means (7) operable by a user of the electrosurgical instrument. A control circuit is provided (6) for controlling the RF output, the control circuit (6) being capable of receiving signals from the switching means (7) and causing one or more RF outputs to be supplied to the electrode assembly (3) in response thereto. The electrode assembly (3) includes a component (14), (21) capable of modifying the RF output reaching the one or more electrodes (12), (13) to produce a desired RF output at the one or more electrodes.
