Steerable electrosurgical electrode

可转向电烧刀

Abstract

本发明提供一种可转向电烧刀,其包含把手、控制元件、第一管体、第二管体、第三管体、刀头及电性传输单元。该把手内具有平面区,该控制元件具有复数个定位平面并枢接至该把手,使得该控制元件经由该复数个定位平面其中之一可旋转地抵接至该平面区,该第一管体位于该第二管体内部并枢接至该控制元件,该第三管体则分别通过一第一连杆及一第二连杆与该第二管体及该第一管体连接,且该刀头设于该第三管体前端。使用者可旋转该控制元件使其以不同的定位平面与该平面区接触,以使该第一管体于该第二管体移动,并进而移动该第三管体及该刀头。
A steerable electrosurgical electrode is provided. The steerable electrosurgical electrode comprises a handle, a control element, a first tube, a second tube, a third tube, an electrode and an electrical transmission unit. The handle has a flat area therein, the control element has a plurality of positioning planes and pivotally connects to the handle such that one of the positioning planes rotatably abuts against the flat area, the first tube is positioned inside the second tube and pivotally connected to the control element, the third tube is connected to the second and the first tubes through a first and a second links, respectively, and the electrode is configured at the right end of the third tube. A user may manipulate the control element such that it abuts against the flat area at different positioning planes, to move the first tube inside the second tube, which in turns rotates the third tube and the electrode.
