Abstract
The invention discloses a novel laser dental drill. The novel laser dental drill comprises a high-power laser generator (1) used for drilling a hole in a decayed tooth, a safe-to-eye laser generator (2) for location, a lens group (3) for changing the projection diameter of laser, and a locating device (4) which is used for fixing the high-power laser generator (1), the safe-to-eye laser generator (2) and the lens group (3). During specific treatment, the locating device is used for fixing the laser dental drill; subsequently, a to-be-treated position is aimed by laser beams emitted by the safe-to-eye laser generator (2) and focused by the lens group (4); finally, the high-power laser generator (1) is started to drill the decayed tooth and kill dental pulp.
Description
Art
The invention discloses a kind of laser dental drill system, belong to medical instruments field.
Background technology
Dental caries, is commonly called as decayed tooth, is the common odontopathy of one.It is because tooth glazed layer, dentin layer are because of after antibacterial and acidic materials corrosion, stimulates and produces to Intradental nerve.It is embodied in pain.Because dental nerve is apart from brain close together, therefore having a toothache is unusual pain.For treatment dental caries, mode general is at present: utilize dental drill to bore and open dental caries, and then utilize medicine to kill containing neural dental pulp, recycling amalgam or resin material are filled.This therapeutic modality needs two treatments just can complete usually.Because dental nerve distance brain distance is very near, therefore, brill tooth process is a very painful process.In order to palliate the agonizing sufferings, medical circle at present most effective method is the drilling speed improving dental drill.Namely by by compressed air-driven, worm gear dental drill that rotating speed is up to tens thousand of turns per minute, shorten drilling time.Even if but as just, patient still can feel severe pain over the course for the treatment of.
Although high-speed dental drill can alleviate patient pain to a certain extent, bring very large negative interaction.The temperature lowering water that the drill bit of high speed rotating and drilling tool spray, outwards can sputter with water smoke form, and inject on the eye for the treatment of physician or the baring skin at other positions.If patient suffers from the infectious disease such as HIV, hepatitis B, hepatitis C, then there is infected danger in doctor.
Summary of the invention
Pain when the present invention solves dental caries therapeutic, shorten treatment time, the technical scheme of protection doctor safety is: produce high temperature by high-power laser beam at irradiated dental surface; make the glazed layer of dental caries, dentin layer and dental pulp in the mode of transient evaporation, realize at a high speed, without pain, treatment without potential safety hazard.Specifically: doctor is stationary positioned device (4) on trouble tooth first, and then doctor can open the safe laser generator of eye (2).Afterwards, doctor can adjust adjustable trestle (5), and laser beam that make to launch the safe laser generator of eye (2), that focus on through battery of lens (3) aims at the position that need treat.Then, doctor can adjust the focal length of battery of lens (3), makes to be consistent with needing the aperture of punching to the diameter of eye safety beam.Finally, doctor, after putting on laser protective eyewear or call away to sight line, can open the switch of superpower laser, complete boring.
High power laser light generator (1) in the present invention is high-power laser generator, and its laser produced can produce high temperature in shone thing surface, and makes irradiated object in moment generating gasification.The laser drilling machine used in the operation principle of the high power laser light generator (1) in the present invention and intermetallic composite coating is similar.For ensureing therapeutic effect, the high power laser light generator in the present invention is power adjustable formula laser generator.Doctor can according to the concrete condition of dental caries, adjustment laser generator power and irradiation time.
In the present invention for locate, generating laser to eye safety, be launch lower powered, damage, visual laser emitter can not be produced to bore hole.Use and locate the laser instrument of eye safety, the laser beam that mainly guarantee superpower laser is launched can be irradiated to exactly and need treatment position.
Battery of lens (3) in the present invention, be one group to be positioned at high power laser light emitter (1), to the safe generating laser of eye (2) front, to change high power laser light emitter (1), battery of lens to the lasing beam diameter that the safe generating laser of eye (2) is launched by zoom.The effect of battery of lens (3) is the diameter changing laser beam, to form the hole of required diameter on tooth.For ensureing therapeutic effect, high power laser light generator (1), to the safe generating laser of eye (2)
Positioner (4) in the present invention is for being fixed on the device of suffering from tooth or suffering from tooth peripheral position.This device realizes fixing by bolt or other fixtures.Positioner is provided with and lays the raw device (1) of high power laser light, to the safe laser generator of eye (2), battery of lens (3).Positioner (4) according to treatment needs, A, B axle can be fixed by optional position.
Because laser is a kind of high-energy light beam.It can complete the boring in dental caries in moment.In addition, because the dental pulp containing nerve also can at transient evaporation, therefore, adopt laser drill, patient does not have pain completely.3rd, because laser drill is thermal boring, the tissue that laser beam irradiation arrives at transient evaporation, thus also can not form security threat to healthcare givers.4th, because high power laser light can make dental pulp gasify, thus can save in therapeutic process and kill this process of dental pulp.Therapeutic process can greatly simplify, and removes the trouble that patient repeatedly comes and goes hospitalize from.
But should see, because laser beam has high energy, thus itself is also with certain potential safety hazard.First, if mishandling, once laser beam injects eyes, then permanent loss vision can be caused; Secondly, if do not fixed in operating process, laser beam may penetrate the buccal or dental bed of wearing patient.For avoiding the generation of contingency, the laser beam that the present invention adopts positioner (4) to guarantee that high power laser light generator (1) is launched can be irradiated to the position needing treatment exactly, and is unlikely to cause malpractice because of deviation position.Secondly, the present invention adopts the safe laser generator of eye (2) as treatment provides prior location, determines diameter work.3rd, present invention employs battery of lens, battery of lens can change diameter to the safe laser instrument of eye (2), high power laser light generator (1) institute Emission Lasers bundle by zoom, makes it consistent with dental caries size, form trait.
Because laser dental drill structure involved in the present invention is simple, volume is little, thus can be fabricated to the portable prostate treatment device utilizing alternating current or DC source.Thus the price of dentist devices is significantly reduced.

Detailed description of the invention
Embodiment 1
The technical scheme that embodiment 1 adopts is, by high-duty laser generator (1), is all arranged on positioner (4) the safe laser generator of eye (2), battery of lens (3).High power laser light generator (1), the safe laser generator of eye (2) to be powered by external cable.Doctor, after completing location, adjusting laser beam spot sizes, can start superpower laser.
The technical scheme difference from Example 1 of embodiment 2 is, by high power laser light generator (1), places independent of positioner (4) and battery of lens (3) the safe laser generator of eye (2).High power laser light generator (1) is passed to battery of lens (3) to the laser beam that the safe laser generator of eye (2) is launched by optical fiber.
The technical scheme of embodiment 3 and embodiment 1,2 different with being, except high power laser light generator (1) with to except the safe laser generator of eye (2) in system, a laser generator that filling light-cured resin can be made to solidify can also be installed additional, to realize the photocuring of boring and potting resin.
