Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1-5, an annular eyelid retractor comprising: the spring bracket 1, the fixed ring 2 and the adjusting buckle 3;

The appearance of the spring frame 1 is similar to the shape of the eye curve of a human body, the left side is provided with the adjusting buckle 3, the middle position is provided with the fixed ring 2 for opening the eyelid, and the right side is provided with the spiral ring 4.

In this embodiment, the spring frame 1 is composed of 3 parts, the upper end position is an upper arc rod 11, the lower end is a lower arc rod 12, the right end position is provided with a spiral ring 4, the upper arc rod 11 and the lower arc rod 12 have the same shape, the concave faces are opposite in direction, and the transverse horizontal lengths of the left and right endpoints of the two rods are 3 cm-5 cm.

In this embodiment, the fixing rings 2 are integrally formed on the upper arc rod 11 and the lower arc rod 12, and face inwards.

In this embodiment, the adjusting buckle 3 is disposed at a position between the upper arc rod 11 and the lower arc rod 12 on the left side, the upper arc rod 11 is connected with the upper rod 31 of the adjusting buckle 3, a positioning pin 3101 perpendicular to the upper rod 31 is disposed on the upper rod 31, the lower arc rod 12 is connected with the lower rod 32 of the adjusting buckle 3, and the lower rod 32 is horizontally provided with a linear array of positioning holes 3201, which are different in number, and the positioning pins 3101 are in clearance fit with the positioning holes 3201.

In this embodiment, the fixing ring 2 is disposed on the upper arc rod 11 and the lower arc rod 12, and the fixing ring 2 has a structure in which two rods are horizontally disposed at a connection position with the spring frame 1, and then bent downward to form a "U" shape, and then the two rods are bent and connected together along a horizontal direction, and also form a "U" shape.

In this embodiment, the spiral ring 4 connects the upper arc rod 11 and the lower arc rod 12, and is an arc-shaped curved structure at a connection position of the upper arc rod 11 and the lower arc rod 12, and is circular in top view.

In this embodiment, the process of developing and designing the above structural features is specifically described by the inventor:

The inventor performs ophthalmic related work for a long time, eye examination and operation are needed to be carried out on patients, but the eyelid spreader used in the diagnosis and treatment process is not suitable for all patients, and some patients have different degrees of damage to eyes after using, so the inventor aims to carry out improvement and innovation on the traditional eyelid spreader.

First, the inventor changes the number of the fixing rings 1 from one pair to two pairs, the size becomes smaller, the damage to the eyelid is reduced, and the improvement greatly lightens the eye burden of the patient.

However, the problem of the universality of the eyelid retractor is not solved, so that the inventor designs the adjusting buckle 3 to realize the size adjustment of the eyelid retractor after inquiring the opinion of colleagues, and the eyelid retractor can be used by both children and adults, so that the application range of the eyelid retractor is wider.

Example 2

In this embodiment, the method using the present utility model is:

When the utility model is used, the fixed ring 2 is firstly placed at the eyelid of a patient to fix, the U-shaped structure of the fixed ring 2 hooks the upper eyelid and the lower eyelid of the patient, because the utility model uses the spring frame 1 with elasticity, the spring frame 1 needs to be compressed when the fixed ring 2 is placed, the upper arc rod 11 and the lower arc rod 12 are pressed downwards, the spiral ring 4 does not interfere with each other when the upper arc rod 11 and the lower arc rod 12 are compressed, medical staff can apply force to compress the spring frame 1 more easily, after the fixed ring 2 is placed, the spring frame 1 is not compressed any more, at the moment, the upper arc rod 11 and the lower arc rod 12 rebound, so that the eyelid opening function is realized, when the fixed ring 2 is opened to a proper position, a proper positioning hole 3201 is selected for matching by the positioning pin 3101 of the adjusting buckle 3, and after the positioning pin 3101 is placed into the positioning hole 3201, the whole device is fixed.
