The utility model discloses an A-V type strabism inspection auxiliary device, which comprises a binding belt, wherein a plastic box is fixedly connected to the left wall and the right wall of the binding belt through glue respectively, a dial is fixedly connected to the inner walls of one side, which are close to the two plastic boxes, of the binding belt through screws respectively, a pointer is movably connected to the inner walls of one side, which are close to the two plastic boxes, of the binding belt through a rotating shaft and a bearing respectively, a connecting rod is fixedly connected to the bottom of the pointer through welding, an iron ball is fixedly connected to the bottom of the connecting rod through welding, and the effect that the pointer is always vertical to the horizontal plane can be realized through the mutual matching among the plastic boxes, the dial, the pointer and the iron ball, so that a tester can intuitively observe whether the rotation angle of an upper eyeball or a lower eyeball of the tester reaches an angle conforming to the A-V type strabism inspection, errors caused by estimation are avoided, and the accuracy of the device is effectively improved.

Description

A-V type strabismus inspection auxiliary device

Technical Field

The utility model relates to the technical field of ophthalmic inspection, in particular to an A-V type strabismus inspection auxiliary device.

Background

In the a-V type strabismus examination, the strabismus angles of the eyeballs when the eyeballs rotate up to 25 degrees, 0 degrees and down to 25 degrees are required to be checked and the eyeballs are watched at the sighting marks of five meters, and the diseases are diagnosed and the surgical treatment scheme is formulated through the checked strabismus angles. The prior ophthalmic inspection equipment only has the advantage that the same vision machine can realize the accurate measurement of the upper corner and the lower corner of the eyeball, but the measurement error of the strabismus angle is easy to cause due to the proximity collection during the inspection of the same vision machine, which is not beneficial to the formulation of an operation scheme, and when the strabismus operation scheme is prepared, a triple prism is generally used for measuring the strabismus angle. When using the triple prism to measure the oblique angle, at present, no tool capable of accurately assisting in measuring the upper corner and the lower corner of the eyeball is available, whether the upper corner and the lower corner are in place or not is often judged by the estimation of an inspector, and the defect of insufficient accuracy is caused.

Disclosure of Invention

The utility model solves the technical problems of overcoming the defects of the prior art such as insufficient accuracy and the like, and provides an A-V type strabismus inspection auxiliary device. The A-V type strabismus inspection auxiliary device has the characteristics of high accuracy and the like.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an A-V type strabism inspection auxiliary device, includes the bandage, the left wall and the right wall of bandage are respectively through glue fixedly connected with plastic case, and the one side inner wall that two plastic cases are close to is respectively through screw fixedly connected with dial plate, two the one side inner wall that plastic case is close to is respectively through pivot and bearing swing joint have the pointer, and the bottom of pointer is through welded fixedly connected with connecting rod to welded fixedly connected with iron ball is passed through to the bottom of connecting rod.

Preferably, two side walls of one side, far away from the dial plates, are respectively marked with an angle number, and the two dial plates are symmetrically arranged left and right.

Preferably, the angular degrees "30 °" and "45 °" are set in red and the other angular degrees are set in black.

Preferably, the plastic box is made of transparent plastic material.

Preferably, the strap is made of an elastic material.

Compared with the prior art, the utility model has the beneficial effects that:

1. in this technical scheme, through the cooperation between plastics box, dial plate, pointer and the iron ball, can realize that the pointer remains the effect of upwards perpendicular to horizontal plane all the time, can let the intuitive observation of tester, whether the angle of upper eyeball or lower eyeball of testee reaches the angle that accords with the inspection of A-V type strabismus, avoided because the error that the estimation brought to its accuracy has effectually been improved.

2. In this technical scheme, through setting up elastic bandage, have the advantage of wearing comfortable, convenient to use to this device has simple structure ingenious, advantage that the cost of manufacture is low.

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.

Examples: as shown in fig. 1-3, an a-V strabism inspection auxiliary device comprises a binding belt 1, wherein a left wall and a right wall of the binding belt 1 are fixedly connected with plastic boxes 2 through glue respectively, inner walls of one side, close to the two plastic boxes 2, of the other side are fixedly connected with a dial 4 through screws respectively, inner walls of one side, close to the two plastic boxes 2, of the other side are movably connected with a pointer 3 through a rotating shaft and a bearing respectively, the bottom of the pointer 3 is fixedly connected with a connecting rod 5 through welding, and the bottom end of the connecting rod 5 is fixedly connected with an iron ball 6 through welding.

The side walls of the two far sides of the dial plates 4 are respectively marked with an angle number, and the two dial plates 4 are symmetrically arranged left and right;

in this embodiment, through the cooperation between the plastic box 2, the dial 4, the pointer 3 and the iron ball 6, the pointer 3 can always keep the function of being vertical to the horizontal plane upwards, so that a tester can intuitively observe whether the angle of the upper eyeball or the lower eyeball of the tested person reaches the angle conforming to the A-V type strabismus inspection, and errors caused by estimation are avoided, thereby effectively improving the accuracy of the device.
