Problems solved by technology

However, these LED-based designs all have certain deficiencies: (1) Due to the use of LEDs for illumination, the energy distribution of the light in the above-mentioned patents is not uniform
[0005] (3) Since the LED is powered on, it is often necessary to design a complex circuit in the braces
In this way, once the braces have leakage and other phenomena, it will endanger the personal safety of the patient.
[0006] (4) Since the wavelength of the LED light is fixed, each type of braces only uses its fixed wavelength for special whitening or treatment, which limits their use
[0007] (5) There is a certain heating phenomenon in the LED and its auxiliary circuits, but in actual use, it is difficult to derive this heating through cooling methods
This creates the possibility of a certain hot spot in the braces, with the risk of damage to the braces as the temperature continues to rise
[0008] (6) Since this type of braces uses LEDs and corresponds to the circuit board, the cost is high and cannot be made into disposable consumables, so there is a risk of cross-infection between different patients due to incomplete disinfection
[0009] (7) Although the lasers commonly used in dental clinics have a 30° bend, this type of optical fiber is not disposable. After the treatment of the patient, the end face of the optical fiber needs to be cut off due to the contamination of the end face. The method can only ensure that the optical fiber is directed forward, and there will be a dead angle in the case of a complex oral environment.
thereby affecting the therapeutic effect

Embodiment 1

[0037] like figure 1 As shown, the optical fiber equipment for laser oral treatment includes SMA905 adapter interface 1, quartz light guide optical fiber 2, optical fiber handle 3 (for dental use), adapter joint 4, fan and optical fiber needle 5 (for disposable consumables, plug and play used, hygienic and clean); wherein, one end of the quartz light-guiding optical fiber is an adapter interface, which is used to guide the laser energy output by the laser therapy machine into the optical fiber and then export it to the patient's oral cavity through the optical fiber handle, and the other end is connected to the optical fiber The handle is coupled and connected. The optical fiber handle is a pen-shaped cylinder structure with a diameter of 1 cm and a length of 14 cm to facilitate the dentist to hold. The end of the optical fiber handle is an adapter joint, which is fixedly connected to the optical fiber needle. The adapter The connector is a small piece of metal column, which c...

Embodiment 2

[0039] like figure 2 As shown, the optical fiber device for laser oral treatment includes an SMA905 adapter interface 1, a quartz light-guiding optical fiber 2, an optical fiber handle 3 (for dental use), an adapter connector 4 and an optical fiber dental brace set, and the optical fiber dental brace set is composed of a whole body shiny optical fiber Interface 6, optical fiber sheath 7, whole body shiny optical fiber 8 and braces 9 (disposable consumables, plug and play, hygienic and clean). The optical fiber is used to generate uniform scattered laser light to achieve the purpose of weak laser light and photodynamic therapy. Since the side-emitting plastic optical fiber is very soft, it can be wound on the braces for multiple turns without damage and light leakage. The whole body is bright The interface is fixedly connected with the whole body shiny optical fiber and the tooth cover in turn, and the optical fiber sheath is nested outside the whole body shiny fiber; wherein,...

Abstract

Provided is an optical fiber device for laser oral treatment, the device comprising: an adapter interface, a quartz light guide optical fiber, an optical fiber handle, an adapter connector and an optical fiber component. The optical fiber component is an optical fiber needle or an optical fiber dental mouthpiece set; the optical fiber dental mouthpiece set consists of an entire-body-illuminating optical fiber interface, an optical fiber sheath, an entire-body-illuminating optical fiber and a dental mouthpiece, the entire-body-illuminating optical fiber interface being fixedly connected to the entire-body-illuminating optical fiber and the dental mouthpiece in sequence, and the optical fiber sheath nesting outside the entire-body-illuminating optical fiber. One end of the quartz light guide optical fiber is the adapter interface, and the other end thereof is coupled to the optical fiber handle, the tip of the optical fiber handle being the adapter connector fixedly connected to the optical fiber component. The optical fiber device for laser oral treatment can facilitate periodontitis treatment and healing of wound by using weak laser, thus accelerating the healing of an oral ulcer and the treatment of photodynamic tooth whitening.

Description

technical field [0001] The invention relates to a medical device, in particular to an optical fiber device for laser oral treatment. Background technique [0002] In the phototherapy device of the patent CN 202682583U, a dental brace that uses a semiconductor laser tube for irradiation is introduced. The dental brace is connected to the front end of the fixing seat where the laser tube is located, and is used to realize irradiation phototherapy. This method cannot cause the effect of uniform light emission in the whole braces, and the device has a large volume, and its fixing seat is placed horizontally. Therefore can't realize the patient's use under the supine treatment situation of department of stomatology clinical. [0003] In the patents CN201120047604-a portable LED cold light tooth whitening device, CN200620017458-cold light whitening braces, CN201180028470-teeth bleaching device, CN200620148456-teeth bleaching device, and CN200410082640-braces, a light-emitting bra...
