Oral implantable wireless power supply light-emitting micro device capable of promoting dental tissue repair

Abstract

The invention discloses an oral implantable wireless power supply light-emitting micro device capable of promoting dental tissue repair. According to the invention, a resonance coil system is adoptedfor supplying power, so problems of wire abrasion, wire exposure and poor contact and potential safety hazards easily caused by a traditional wire connection power supply manner or the problems of limited battery size, limited service life, troublesome replacement and the like for a traditional battery power supply manner are solved, and more convenience and safety are achieved; and energy transmission is realized under the action of a high-frequency alternating magnetic field through the electromagnetic induction effect of an in-vitro transmitting coil and an in-vivo receiving coil, so continuous power supply can be provided for an LED phototherapy lamp implanted into an oral cavity in the treatment process, and a reliable optimal scheme is provided for long-term electric energy supply ofan implanted device.

Description

technical field [0001] The invention belongs to the field of dental medicine, and in particular relates to an oral cavity implantable wireless power supply light-emitting micro-device that can promote dental tissue repair. Background technique [0002] One of the main goals of dental medicine is to restore the oral system, restoring tissue damage, defects or wounds caused by trauma, disease, atrophy or surgery. For example, in oral surgery, the most common postoperative wounds are wounds located near the oral mucosa or jawbone. Tooth extraction is one of the most commonly used surgical methods (such as tooth extraction when removing a tumor). Generally speaking, due to the long healing period of the tissue, these postoperative wounds need to take appropriate measures for nursing and treatment, otherwise some serious complications may be caused and bring great discomfort to the patient. One of the most common complications is the dry extraction socket after tooth extraction...

AI Technical Summary

Problems solved by technology

[0005] ① The structure of the oral cavity is complex, and some tissues are not easy to receive light therapy from the outside

[0006] ②Complicated operation and inconvenient treatment

This also brings inconvenience to the patient to a certain extent.

[0007] ③ It is difficult to adjust the light source as needed

However, during this period, patients are often unable to adjust parameters such as light time, light intensity, and light source wavelength according to their own treatment needs due to some practical factors (such as high treatment costs and limited number of instruments); Even portable or wearable LED phototherapy devices are driven by batteries, and it is difficult to guarantee the flexibility and convenience of their applications

[0008] ④Wavelength limitation

However, the characteristics of the laser determine that no matter which output mode it is in, the wavelength of the light it can output is relatively fixed, and it cannot cover all the visible light and near-infrared light bands that can be used in biomedicine.

This also limits the application of lasers in some aspects of oral phototherapy

[0009] ⑤ Security issues

Due to cost issues, most laser systems are not originally designed for medical use, but are designed for scientific research and other non-medical applications, so it is easy to cause certain safety problems when they are used again for medical use

Traditional gas lasers require a high-voltage supply and a complex gas-liquid cooling system for cooling, which can easily cause certain safety hazards
