Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to ophthalmology slit lamp auxiliary lighting device.
Background
The eye is the most important organ in human sense, and about 80% of the knowledge in the brain is acquired by the eye. The eyes are needed to read the books and recognize words, watch pictures, watch figures, enjoy beautiful scenery and the like.
The slit-lamp microscope is an important instrument which is not necessary to be few in ophthalmologic examination, is also the first extensive basic instrument for ophthalmologic routine examination, and is required to be forcibly configured in industries and countries such as ophthalmologic diagnosis and treatment, ophthalmologic health care, optometry lens matching and the like.
Throughout the world, from the smallest otolaryngological clinic to the large eye hospitals to the top-grade eye disease research institutions, ophthalmic slit-lamp microscopes are the most specialized devices for examining the eyelids, conjunctiva, sclera, cornea, anterior chamber, iris, pupil, lens and anterior 1/3 vitreous body to determine the location, nature, size and depth of lesions.
The ophthalmic slit-lamp microscope is widely used by medical institutions, ophthalmic health care institutions and spectacle chain stores, and the function expansion and improvement on the instrument play an important role in human eye health.
The structure of the slit lamp mainly comprises four parts: the device comprises a slit illuminating mechanism, a microscope optical body, a moving platform mechanism and a chin rest mechanism.
The slit lamp at the present stage is provided with an auxiliary lighting mechanism which is arranged on the following parts of the slit lamp:
1. the auxiliary lighting mechanism is arranged around the reflective mirror of the crack lighting mechanism, for example, the auxiliary lighting mechanism is arranged at the upper part of the reflective mirror of the crack lighting mechanism, the emitted light irradiates the surface of the eyes through the transmitting mirror, and is also arranged at the lower part of the reflective mirror of the crack lighting mechanism, the emitted light directly irradiates the surface of the eyes in an inclined way;
2. the auxiliary illuminating mechanism is arranged in the left and right rotating shaft holes of the slit illuminating mechanism, and the emitted light is directly obliquely irradiated on the surface of eyes.
These auxiliary lighting devices all suffer from the following disadvantages:
1. the auxiliary illuminating mechanism is arranged on the slit illuminating mechanism, and when the auxiliary illuminating mechanism is used, the auxiliary illuminating light is required to be adjusted left and right, so that the auxiliary illuminating light can irradiate a required position, and the auxiliary illuminating light is inconvenient to use, for example, when the optical body is moved left and right, the auxiliary illuminating mechanism is required to be moved left and right, so that the light can uniformly irradiate an inspection position.
2. Light rays, whether reflected by a reflector or directly emitted, are emitted from one direction (corresponding to a point light source), and are easily blocked by a forward object, causing uneven illumination, such as the eyelashes.
3. Slit lamps also require more auxiliary light of different wavelengths to illuminate, requiring increased positioning.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's is not enough, and this patent has increased an auxiliary lighting device on the slit lamp, and it removes along with the slit lamp optics body, can solve auxiliary lighting's multi-angle and shine the problem. The auxiliary lighting device for the ophthalmic slit lamp is provided aiming at the problems, and the specific technical scheme is as follows:
the utility model provides an ophthalmology slit lamp auxiliary lighting device, includes the objective seat, its characterized in that: the objective lens seat is characterized by further comprising a support and an illuminating lamp, wherein the support is arranged on the objective lens seat, and the illuminating lamp is arranged on the support.
Further: the two brackets are respectively arranged on two sides of the end surface of the objective lens seat, the slit lamp large objective lens barrel is positioned between the two brackets, and an illuminating lamp is arranged on each bracket.
Further: the illuminating lamp is an LED lamp.
Further: the wiring of the illuminating lamp is hidden in the objective lens seat.
The utility model has the advantages that:
firstly, the structure is simple, the realization is convenient, and the lamp wire is also convenient to hide in the machine body;
second, the auxiliary lighting devices are disposed on both sides of the microscope for observing the optical body, so that the illumination angle is larger, the illumination position is wider, and the auxiliary lighting devices can follow the optical body by rotating left and right.
Thirdly, a new part is added with an auxiliary lighting device, and the auxiliary lighting function of the original part is kept.
