Description

A combined mechanical and electrical interface for a slit lamp mounting attachment

technical field

The invention relates to the field of medical equipment, in particular to a mechanical and electrical integrated interface of a slit lamp mounting attachment.

Background technique

The eyes are the most important organ of the human senses, and about 80% of the knowledge in the brain is acquired through the eyes. Reading and recognizing characters, seeing pictures and pictures, seeing people, and enjoying beautiful scenery all use the eyes.

Slit lamp microscope is an essential instrument for ophthalmic examination, and it is also the most widely used basic instrument for routine ophthalmic examination.

In the world, from the smallest ENT clinic to the largest eye hospital to the top ophthalmic disease research institutions, the ophthalmic slit lamp microscope is used to examine the eyelid, conjunctiva, sclera, cornea, anterior chamber, iris, pupil, lens and anterior 1 /3 Vitreous body, the most professional equipment to determine the location, nature, size and depth of lesions.

Ophthalmic slit lamp microscopes are widely used by medical institutions, ophthalmic health care institutions, and chain stores of spectacles. The expansion and improvement of functions on the instrument play an important role in human eye health.

The structure of the slit lamp is mainly composed of four parts: the slit illumination mechanism, the microscope optical body, the moving platform mechanism, and the chin rest mechanism. Among them, the most important two parts are the slit illumination mechanism and the microscope optical body.

In order to expand the function of the slit lamp, functional accessories have been added, such as a dry eye projection (illumination) device for dry eye (an eye disease) examination. There is a dry eye projection (illumination) device installed on the slit lamp illumination shaft. in the inner hole. The inner hole of the illumination shaft is located directly under the eyes of the examinee. The axis of the inner hole is also the common rotation axis of the microscope optical body and the slit illumination part. The shaft has sufficient strength to install functional accessories, and the shaft body has enough space to set other parts. At present, the inner hole of the lighting shaft is only used as a mechanical connection hole, and there is no electrical connection. Therefore, the cables of the electric accessories inserted into the inner hole are exposed outside the slit lamp (the additional dry eye projection device of the slit lamp of CSO company in Italy). The cable is placed outside), the disadvantages are: 1. Due to the dragging of the cable, the movement of the slit lamp and additional functional devices is affected, 2. The movement of the cable causes the connection to be unreliable, 3. When not in use, the accessories need to be removed, The accessories with cables are inconvenient for storage and unreliable, and 4. affect the appearance of the entire slit lamp.

SUMMARY OF THE INVENTION

Aiming at the deficiencies of the prior art, the present invention designs a mechanical and electrical integrated interface for the electrical accessories connected to the lighting shaft of the slit lamp, and through the integrated interface connection, a plug-and-play machine with reliable performance and diversified cable connections is obtained. and electrical connections.

This mechanical and electrical connection can be used for accessories for dry eye examinations, as well as for other powered accessories installed here.

Therefore, the present invention proposes a mechanical and electrical integrated interface for installing an additional device for a slit lamp, and the specific technical scheme is as follows:

A mechanical and electrical integrated interface for installing an additional device for a slit lamp, including a lighting rotating shaft and an additional device, and is characterized in that: it also includes an insertion part, a first connecting piece and a second connecting piece;

An inserting part and a first connecting piece are arranged on the additional device, and a second connecting piece is arranged inside the lighting rotating shaft;

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

When in use, the inserting part is inserted into the inner hole of the lighting rotating shaft, and the first connecting part and the second connecting part form a connection to realize mechanical and electrical connection.

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

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

Further: the internal cable of the additional device is electrically connected to the first connector through the insertion part;

An inner cable is arranged inside the lighting rotating shaft, and the inner cable is electrically connected with the second connecting piece.

The beneficial effects of the present invention are as follows: first, the overall structure is simple, and it can be plug-and-play, which can perform both mechanical structure insertion connection and electrical connection, and becomes a general mechanical and electrical integrated interface.

Second, the cables are hidden inside the lighting shaft of the slit lamp and inside the additional device inserted into the inner hole of the lighting shaft, which is not affected by the use of plugging and storage, and has no contact with the outside world, which improves the practicability, reliability and aesthetics of the connection. sex.
