Abstract
A magnet for an ophthalmologic operation comprises a magnet head and a handle, wherein the magnet head is installed at the front end of the handle. The handle is of a hollow circular structure, an electromagnet, a current control board and a lithium battery are arranged inside the handle, one end of an electromagnet core is connected with the magnet head into a whole, and the tail end portion of the handle is provided with a current regulator and a charging jack; the lithium battery, the current regulator and the electromagnet are electrically connected with the current control board, and the lithium battery is connected with the charging jack in parallel; the current regulator is a combined piece with a switch and an adjustable resistor. Compared with the prior art, the magnet for the ophthalmologic operation has the advantages of being reasonable in design, simple in structure, and high in practicability. The intensity of magnetism is large and does not attenuate, and convenience is brought to work of medical personnel.
Description
Technical field
This utility model relates to a kind of ophthalmic medical apparatus, is specifically related to a kind of ophthalmologic operation dedicated suction ironware.
Background technology
In the ophthalmologic operation to eyeball mechanical injury, often can use a kind of ophthalmology permanent magnet magnet, with the iron filings class foreign body of leaving in the sucking-off eyeball.Existing ophthalmologic operation is made of bullet shape sucking head and the fixing handle of its tail end with the permanent magnet magnet.Due to permanent magnet directly being installed in sucking head, its magnetic intensity necessarily and is in time passed, and magnetic also can decay, and brings work inconvenience to medical personnel.
Summary of the invention
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of ophthalmologic operation dedicated suction ironware is provided.
Its technical scheme is: comprise and inhale ferrum head and handle, inhale the front end that the ferrum head is arranged on handle.Described handle is the circular configuration of interior sky, is provided with electric magnet, Current Control plate and lithium battery in handle, and an end of described electromagnet core connects as one with inhaling the ferrum head, and the tail end of handle is provided with rheonome and charging jack; Described lithium battery, rheonome, electric magnet all are electrically connected to the Current Control plate, and lithium battery is connected in parallel with the charging jack; Described rheonome is the molectron with switch and adjustable resistance.
Described Current Control plate is comprised of the first audion, the second audion, the first resistance, the second resistance and electric capacity; Described lithium battery one end is connected with an end of adjustable resistance, the colelctor electrode of the first audion and the colelctor electrode of the second audion by switch, the other end of adjustable resistance is connected with an end of the second resistance and the base stage of the first audion by the first resistance, the emitter stage of the first audion is connected with the base stage of the second audion, the second audion emitter stage be connected with the positive pole of electric capacity and an end of electric magnet.The other end of electric magnet is connected with the other end and the lithium battery other end of the negative pole of electric capacity, the second resistance, and lithium battery is connected in parallel with the charging jack.
This utility model has the following advantages compared with prior art: reasonable in design, simple in structure, practical.Its magnetic intensity can be decayed greatly and not, brings convenience for medical personnel's work.
Description of drawings
