A platform for preparing micro-textured electrodes for deep brain stimulation cannula

Abstract

The invention discloses a platform for preparing a micro-texture structure of a cannula electrode for deep brain stimulation, including a base, a space pose adjustment device, a positioning clamping device, an online observation device, a laser processing device, and a positioning support device; the space pose The adjustment device includes a bottom plate, a worktable, an adjusting screw and a rotating arm. The bottom plate is installed on the base, the middle part of the worktable is connected to the bottom plate in rotation, and the adjustment screw is rotatably arranged on the worktable. The upper end of the rotating arm is rotatably connected to the connecting rod, the adjusting screw is threadedly connected to the connecting rod, and the lower end of the rotating arm is rotatably connected to the bottom plate. The beneficial effect of the present invention is that the thin-walled hollow sleeve electrode can be stably clamped , to prevent the thin-walled hollow sleeve electrode from being deformed due to clamping; realize the guiding and supporting function of the thin-walled hollow sleeve electrode, which can not only ensure the straightness of the sleeve electrode, but also limit the rotation runout error of the sleeve electrode.

Description

technical field [0001] The invention belongs to the technical field of deep brain puncture intervention, and in particular relates to a micro-texture processing device for a cannula electrode. Background technique [0002] With the growth of human age and the increase of pressure, some neural nuclei in the deep part of the brain will become dysfunctional, which will lead to a series of mental activity or movement disorder diseases, the typical case of which is Parkinson's disease. Currently, deep brain stimulation is the best treatment for this condition. [0003] In deep brain stimulation surgery, the cannula electrode is punctured from the middle frontal gyrus to the target area in a straight line along the brain parenchyma, and the length of the puncture path is about 50 mm. During the puncture process, the surface of the cannula electrode and the brain tissue generate puncture friction due to relative movement. As the puncture depth increased, the puncture friction inc...

Problems solved by technology

[0008] The processing difficulty of the micro-textured sleeve electrode lies in: the thin-walled hollow sleeve electrode is easy to be clamped and deformed, the rigidity of the thin-walled hollow sleeve electrode with a large aspect ratio is low, and the straightness is difficult to maintain, and the rotation of the sleeve electrode with a large aspect ratio And run-out accuracy is difficult to guarantee, the collinearity between the laser beam and the busbar on the casing electrode is difficult to adjust flexibly, and the micro-texture processing is inconvenient for real-time online multi-angle flexible observation, etc.

Therefore, the machining error of the micro-texture on the micro-textured sleeve electrode is relatively large, and it is difficult to guarantee the machining accuracy and efficiency.
