Title
(EN) Surgical resection device
(ZH) 外科用切除装置
Abstract
(EN)
A surgical organ resection device comprising a plurality of elongate electrodes (4) for insertion into organ tissue, the electrodes being capable of operating in a bipolar manner, and an input for receiving a drive signal for driving the electrode, the elongate electrodes being arranged in a two-dimensional array and/or the device being arranged such that, in use, subsets of the elongate electrodes are driven in turn.

(ZH)

本发明涉及外科用切除装置。一种外科用器官切除装置,包括多个用于插入到器官组织中的能够以双极方式工作的长电极(4),以及用于接收驱动长电极的无线电频率驱动信号的输入端,所述多个长电极包括两组或更多组以二维阵列布置的长电极,当长电极连接到无线电频率发生器并用合适的无线电频率能量来驱动时,紧靠长电极的组织被加热,组织受热会使脉管封闭,从而防止在后续的切除中失血。所述装置还可以设置成在使用中依次驱动长电极的子集。
