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)，所述电极组件包括一个或更多个电极(12)、(13)和连接器(8)、(9)，所述电极组件(3)通过所述连接器(8)、(9)能够相对于所述手持件(2)被附接和分离。所述手持件包括电池(4)、用于产生射频RF输出的RF振荡电路(30)、RF输出电路(5)以及能够由所述电外科器械的使用者操作的开关装置(7)。控制电路(6)被设置用于控制所述RF输出，所述控制电路(6)能够从所述开关装置(7)接收信号，并且响应于所述信号而使一个或更多个RF输出被提供至所述电极组件(3)。所述RF输出电路包括变压器，所述变压器包括至少一个一次绕组(14)和多个二次绕组(15)、(16)、(17)。所述电极组件上的所述连接器(9)包括部件(29)，所述部件(29)能够物理选择特定二次绕组或二次绕组的组合，以便改变到达所述一个或更多个电极的所述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 (30) for generating a radio frequency output, an RF output circuit (5) 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 RF output circuit includes a transformer including at least one primary winding (14) and a plurality of secondary windings (15), (16), (17). The connector on the electrode assembly (9) includes a component (29) capable of physically selecting a particular secondary winding or combination of secondary windings so as to modify the RF output reaching the one or more electrodes.
