Abstract
The utility model provides an eyelid expander, belonging to the technical field of a medical appliance. The eyelid expander comprises an upper distraction arm and a lower distraction arm, and is characterized in that the upper distraction arm and the lower distraction arm are respectively articulated at both ends of a main girder; an upper auxiliary arm and a lower auxiliary arm are respectively articulated on the upper distraction arm and the lower distraction arm, and are respectively articulated at both ends of an auxiliary girder; two sections of screw thread with opposite heading directions are arranged on a screw; the auxiliary girder is connected with the front section screw thread of the screw by screw thread; the main girder is connected with the rear section screw thread of the screw by screw thread; the main girder and the auxiliary girder are arranged in parallel; the rear end of the screw is provided with a rotating leaf; and the end parts of the upper distraction arm and the lower distraction arm are provided with eyelid holders. In the utility model, through the arrangement of two opposite sections of screw thread on the screw, the expansion and contraction of the eyelid holders are realized under the combined action of the distraction arm, the auxiliary arm, the main girder and the auxiliary girder, the screw thread regulation can be accurately operated, the medical effect is improved, and the safety is ensured.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of eye-speculum.
Background technology
Eyelid can cover by active eyelid, is commonly called as eyelid, is positioned at eyeball the place ahead, constitutes the barrier of protection eyeball.With the protection eyeball and outermostly be easy to injured cornea, and has the effect that tear is spread to whole conjunctiva and cornea.General, during operation aspect doing eyeball, because the physiological reaction of closing one's eyes of human body itself, need strut eyelid with the exposure eyeball by mechanical means usually and be convenient to the carrying out of performing the operation, the apparatus structure of prior art is single, what have must be fixed by artificial or other apparatuses, make it in operation process, to exist danger to a certain extent, may damage eyeball, and its degree of accuracy that struts is not high, strut distance and be difficult to control and adjusting, this brings very big obstacle to Rhizoma Atractylodis Macrocephalae.How to design a kind of dilator safe, stable, that accurately help auxiliary operation on eyeball and be present stage ophthalmology medical science an important topic to be solved is arranged.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of eye-speculum is provided.
The technical solution of the utility model realizes in the following manner, this eye-speculum, comprise and strut arm, under strut arm, its structure struts arm and struts the two ends that arm is hinged on girder respectively down on being, on strut arm and strut down and be hinged with auxiliary and following auxiliary on the arm respectively, last auxiliary and following auxiliary are hinged on the two ends of auxiliary girder respectively, one screw rod is provided with two sections opposite screw threads of direction of advance, the leading portion screw thread of auxiliary girder and screw rod is by being threaded, the back segment screw thread of girder and screw rod is by being threaded, girder and auxiliary girder be arranged in parallel, and spiro rod rear end is provided with the rotation leaf, on the end that struts arm and strut down arm be provided with the eyelid holder.
Be provided with central limited block between two sections screw threads on the screw rod, the front end of screw thread and end are provided with front end limited block and terminal limited block on the screw rod.
The eyelid holder is an arc.
The beneficial effect that this utility model is compared with prior art produced is:
This eye-speculum is by the setting of two sections opposite threads on the screw rod; rotate leaf with hands in use; thereby screw rod promptly rotates to drive and realizes between girder and the auxiliary girder drawing back and contracting near; strut arm in the cooperation and strut down arm, expansion that the combined effect of going up auxiliary and following auxiliary realizes the eyelid holder moves with drawing in; threaded adjusting more can accurately be operated; improve medical effect, the holder of arc eyelid more can protect eyelid can not be subjected to the injury of apparatus when expansion, and safety is secure.
