Problems solved by technology

However, this method requires surgery to implant electrodes, and it cannot affect the facial muscle groups, so this method has limited practical significance for restoring the motor function of muscle groups.
[0006] U.S. Patent No.: US7,874,838, "Instrument and process for the minimum distance verification between teeth for the placement of one or two bone integrated dental implants" (instrument and process for the minimum distance verification of one or two implant placement ), which discloses a method involving improving the effectiveness of denture implantation, which to a certain extent provides a new idea for the installation of removable dentures, but this technology does not have an impact on the rehabilitation of facial paralysis
U.S. Patent No.: US7,857,626, "Medical physiological simulator including a conductive elastomer layer" (medical physiological stimulator including a conductive elastic layer), which discloses a method of using a conductive elastic circuit layer as a feedback path to control physiological electrical stimulation A method, but this technology is mainly oriented to surgical skills training, and its practical significance as a rehabilitation treatment is limited
In summary, no matter whether it is related to dentures or electrical stimulation, there is no active denture-type flexible microelectrode that can be used for facial paralysis rehabilitation by combining the two.

Embodiment

[0028] The specific preparation process of this example is as follows: first deposit a 3 μm-5 μm polychlorinated p-xylylene (Parylene-C) film on the Si wafer, and then throw 0.01 mm-1 mm polydimethylsiloxane (PDMS), 80 ℃ drying for 4 hours to form a structural layer. Then throw 5μm positive resist and pattern it, sputter noble metal (including Pt, Ir, Au, etc.) seed layer, 100-15000 Angstroms, use Lift-off process to remove photoresist, pattern the seed layer, and form the electrode circuit layer. Then, throw 0.01mm-1mm PDMS, dry at 80°C for 4 hours, then deposit 3μm-5μm Parylene-C, pattern the photoresist for the second time, use reactive ion etching (RIE) to remove Parylene-C Cut through to expose the electrode points to form the covering layer.

[0029] Such as Figure 1-Figure 3 As shown, the removable denture-type flexible microelectrode for facial paralysis prepared in this example includes: a structural layer 1, an electrode circuit layer 2 and a covering layer 3 that...

Abstract

The invention relates to a movable false tooth type flexible microelectrode applicable to facial paralysis rehabilitation in the technical field of medical apparatuses. The movable false tooth type flexible microelectrode comprises a structure layer, an electrode circuit layer, a covering layer and a through hole, wherein the structure layer, the electrode circuit layer and the covering layer are arranged in sequence to form a composite structure; the through hole penetrates through the composite structure; the covering layer is in direct contact with one side or two sides of a paralyzed facial muscle group in an oral cavity; a connection circuit and electrode points are arranged in the electrode circuit layer, wherein the connection circuit is covered by the covering layer and is electrically insulated; and the electrode points are exposed to realize electric stimulation. The flexible microelectrode additionally designed on the basis of a movable false tooth is simple and convenient to wear, needs no surgical operation, does not affect the facial appearance and is a solution for solving the difficult movement of the facial muscle group caused by facial paralysis.

Description

technical field [0001] The invention relates to a device in the technical field of medical devices, in particular to a movable denture type flexible microelectrode for facial paralysis rehabilitation. Background technique [0002] In recent years, with the continuous advancement of micro-electromechanical systems (MEMS: Micro-Electro-Mechanical Systems) technology, the application range of micro-systems such as micro-electronic devices and micro-sensors has continued to expand, and has been widely used in many fields, especially in the medical field. . [0003] Facial paralysis is a kind of common disease that is main feature with facial expression muscle group motor dysfunction, and general symptom is crooked mouth and eyes. Patients are often unable to complete even the most basic movements such as raising eyebrows, closing eyes, and blowing mouth. In patients with complete paralysis of facial expression muscles on the affected side, forehead wrinkles disappear, palpebra...
