System for assisting in implanting electrode wire and method for guiding electrode wire

The present disclosure relates to a system for assisting in implanting an electrode wire, comprising: an electrode wire fixing apparatus; a guide needle fixing apparatus; a movement mechanism; a first camera, arranged on a first side of a plane and towards a metal part, the first camera having a first optical path; a second camera, arranged on the first side of the plane and towards the metal part, the second camera having a second optical path at an angle to the first optical path; and a processing apparatus, configured to identify a relative position of the end of a guide needle to a through hole based on images shot by the first camera and the second camera, and control the movement mechanism to drive the electrode wire fixing apparatus and/or the guide needle fixing apparatus to move, so that the end of the guide needle is aligned with the through hole. The present disclosure further relates to a method for guiding an electrode wire.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B17/3403, A61B17/3468, A61B2017/3409, A61B2034/2057, A61B2090/371). The claims define what a patent protects, and they are not read here.

Surgical access

A probe soft enough for the brain to tolerate is too soft to push in by hand, and each route into the head has its own risk. The problem behind it: placing many contacts exactly, without injuring tissue or vessels, in an operation short and repeatable enough to offer widely.

Interface and electrodes

Everything downstream works with what the contacts pick up. Their number, size and distance from the neurons set the ceiling on the signal. The problem behind it: more contacts, closer to neurons, that still record after years in tissue that reacts to them.

Decoding

This is the step that turns brain activity into a command or a word. Its accuracy and speed are what a user experiences. The problem behind it: accuracy that holds over months without frequent recalibration, for more than one user and one task.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack

Dates as the offices published them. Office records are in the offices' own words and are a selection: refusals, lapses and withdrawals, and records that name an owner. Each concerns one member of the family, not the family as a whole, and another member in the same office may stand. Whether a patent is in force today is not assessed.
