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 with slit lamps in the aspects of 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, wherein the slit illuminating mechanism and the microscope optical body are the most important.

In order to expand the function of the slit lamp, functional accessories such as a dry eye projection (illumination) device for dry eye (an ophthalmic disease) examination are added, and there are dry eye projection (illumination) devices installed in the inner hole of the illumination rotating shaft of the slit lamp. The illumination rotating shaft is provided with an inner hole which is positioned right below the eye of the examinee, the axis of the inner hole is also the common rotating axis of the microscope optical body and the slit illumination component, the rotating shaft has enough strength for installing the functional accessory, and the rotating shaft body has enough space for arranging other components. At present, the inner hole of the lighting rotating shaft is only used as a mechanical connecting hole and is not electrically connected, so that the cable is exposed outside the slit lamp by an accessory device for power utilization inserted into the inner hole (the cable of the slit lamp of the Italy CSO company for attaching the dry eye projection device is placed outside), and the defects are that: 1. the movement of the slit lamp and the additional functional device is influenced by the dragging of the cable, 2, the connection is unreliable due to the movement of the cable, 3, the accessory needs to be taken down when the slit lamp is not used, the accessory with the cable is inconvenient to store and keep, and the unreliable hidden danger exists, and 4, the appearance of the whole slit lamp is influenced.

Disclosure of Invention

Aiming at the defects of the prior art, the invention designs a mechanical and electrical comprehensive interface for the power-consuming accessory of the slit lamp connected to the lighting rotating shaft, and the plug-and-play mechanical and electrical connection with reliable performance and diversified cable connection is obtained through the comprehensive interface connection.

The mechanical and electrical connections may be used for dry eye examination accessories, as well as for other powered accessories mounted therein.

Therefore, the invention provides a mechanical and electrical comprehensive interface for installing an additional device on a slit lamp, which has the following specific technical scheme:

the utility model provides a slit lamp installs machinery and electric comprehensive interface of auxiliary device, includes illumination pivot and auxiliary device, its characterized in that: the device also comprises an insertion part, a first connecting piece and a second connecting piece;

the additional device is provided with an insertion part and a first connecting piece, and a second connecting piece is arranged in the lighting rotating shaft;

the first connecting piece is arranged on the inserting part, and the second connecting piece is arranged at the lower part of the inner hole of the lighting rotating shaft;

when the lighting rotary shaft is used, the insertion part is inserted into the inner hole of the lighting rotary shaft, and the first connecting piece and the second connecting piece are connected to realize mechanical and electrical connection.

Further: the first connecting piece is a socket, and the second connecting piece is a plug.

Further: the first connecting piece is a plug, and the second connecting piece is a socket.

Further: the additional device internal cable passes through the insertion part and is electrically connected with the first connector;

an inner cable is arranged inside the illumination rotating shaft and electrically connected with the second connecting piece.

The invention has the beneficial effects that: first, overall structure is simple, can plug and play, can carry out mechanical structure and insert and connect, can carry out electrical connection again, becomes a general machinery and electrical integrated interface.

Secondly, the cable is hidden inside the slit lamp illumination rotating shaft and inside the additional device inserted into the inner hole of the illumination rotating shaft, is not influenced by the use of pulling, inserting, storing and storing, has no contact with the outside, and improves the practicability, reliability and attractiveness of connection.
