Abstract

The utility model relates to a dental pulp viewer, which comprises a camera, an LED lamp group and a peep tube which are arranged in an oral cavity, wherein the LED lamp group is close to the peep tube, and the LED lamp group and the peep tube are arranged above a lens of the camera together. Accordingly, emitted light rays are more gathered together, are closer to teeth in distance, and can vertically radiate to the bottom of a dental pulp cavity, thereby inlet light quantity is greatly enhanced. The peep tube with a small diameter just allows images at the bottom of the dental pulp cavity to pass through, and can effectively block light rays from directly entering the camera, thereby being capable of directly obtaining clear images at the bottom of the dental pulp cavity, and guaranteeing clear shooting effect. A metal shell and a metal sleeve can effectively and rapidly dissipate heat, the dental pulp viewer is steadier in work performance, is not easy to burn out, and is low in production cost and extremely strong in market competitiveness, thereby being favorable for market development and popularization.

Description

The dental pulp viewer

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of dental equipment, a kind of dental pulp viewer.

Background technology

The dentist is general marrow drain, the excision pain relieving method opened that adopt for patient treatment the time; promptly at first on tooth, prepare nest hole shape, open pulp cavity; clear up the root pipe then; get through apical foramen of tooth; to reduce intrinsic pressure and the drain inflammatory exudate; then bad tissue of excision cleaning dental caries and sterilization nest hole, the pain relieving that also will carry out disinfection covers pulp-cap and at last with silver amalgam or composite resin filling at the bottom of hole, nest hole.But the dentist just operates with its limited visual range and experience in the past in preparation nest hole, during operation such as open pulp cavity and cleaning root pipe, and having a strong impact on operation carries out smoothly, even causes surgical effect undesirable.

For this reason, a lot of manufacturers develop stomatology endoscope, and these stomatology endoscopes comprise a plastic casing, shape and common electric toothbrush are similar, its front end is provided with photographic head and LED lamp, and when putting into the oral cavity, photographic head is oversize, LED lamp angle is too inclined to one side, can't shine depths, dental pulp hole, external teeth is shone very brightly, is turned white on the contrary, and the inside and outside black and white contrast of tooth is big, the image that photographic head is taken can't be seen the grain details of inside, dental pulp hole clearly at all.If adopt to increase the illumination that power improves the LED lamp, still can't resolve problem, can allow LED lamp heating and burning out on the contrary.

In addition, Zeiss (Zeiss) company of Germany has also developed oral cavity root pipe microscope, this microscope is to be placed at the bottom of the dental pulp hole outside the oral cavity about 15CM～25CM taking the photograph camera lens, utilize high intensity cold illumination bright lamp to focus in the dental pulp hole then, can shoot sharp image, but this microscopical photographic head is owing to place outside the oral cavity, make its focusing difficulty on the dental pulp hole bigger, patient during use promptly takes less than the dental pulp hole as long as a moving or microscope is moved a little a little, must readjust the focus point of photographic head focal length and cold light illumination lamp, use inconvenient, very trouble, and cold light illumination lamp places outside the oral cavity simultaneously, arrives the dental pulp hole apart from lengthening, irradiating angle diminishes, allow cold light direct projection go into bottom, dental pulp hole, be inversely proportional to according to illumination and square distance, what power demand must be big is many; Add that it adopts manufacturings such as tele lens, cost and regular maintenance, maintenance cost are all very high, and the purchase that reduces consumer greatly is intended to, and market is difficult to promote, popularize, and the patient uses institute's defrayment also expensive, has increased the patient burden virtually.
