Eyelid retractor for ophthalmologic operation

Abstract

An eyelid retractor for ophthalmologic operation is disclosed in the invention, and comprises retraction plates and an absorption pump, the top ends of the retraction plates are fixedly installed on the lower end faces of supporting rods, the supporting rods are of an arc-shaped structure, the two ends of each supporting rod are each provided with one retracting plate, the middle sections of the sides of the supporting rods are connected with connecting rods, the output ends of the connecting tubes are connected with the input end of the absorption pump, the absorption pump operates to enable the suction holes to be in a negative pressure state through the connecting tubes, a third cavity, a second cavity and a first cavity, and redundant nutrient solution in a designated area is sucked out. According to the eyelid retractor for the ophthalmologic operation, the corresponding cavity and a suction hole structure are formed in the retraction plate serving as an eyelid retraction mechanism, so that the retraction plates have a liquid adsorption function while retracting an eyelid, and the influence on the operation caused by a light refraction effect formed by excessive addition of a nutrient solution is avoided.

Description

technical field [0001] The invention relates to the technical field of ophthalmic equipment, in particular to an eyelid retractor for ophthalmic surgery. Background technique [0002] The eyelid is the eyelid that is often said in people's life, and it plays the role of protecting the eyeball. During the operation of the eyeball area, keeping the eyelid closed after anesthesia will make the operation difficult. Therefore, in the actual operation process, it is necessary to use The corresponding retractor keeps the eyelid open; [0003] For example, the Chinese authorized patent (ophthalmology eyelid opener) whose notification number is CN203075001U: includes a bracket, two support arms are hinged on the support arm, and the end of each support arm is fixedly connected with an eyelid opening hook. There is a screw rod connected to the upper thread, one end of the screw rod is provided with a handle, and the other end is connected with the mounting base, and the two ends of t...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide an eyelid retractor for ophthalmic surgery to solve the above-mentioned background technology. Although the prior art has the function of absorbing nutrient solution, its absorption function passes through a pipeline independent of the lid opening structure. Therefore, during the operation, it needs to occupy a certain amount of operation space, which greatly affects the convenience of the operation in the eyeball area. It is necessary for the medical staff to repeatedly adjust the position of the pipeline structure and the relationship between the bottom end and the eyeball during the operation. The spacing between the two ends greatly reduces the operation efficiency; and the opening structure adjusts the spacing by rotating, and the center of the rotation is located on the side of the eye area. Therefore, the distance between the first and the last ends of the opening structure is inconsistent after rotation, resulting in too much space for local surgical operations. Small, the rotation angle is too large and it is easy to cause damage to the eyelids
