Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1:

referring to fig. 1-2, the novel eye speculum for ophthalmology comprises an installation seat 1, wherein an adjusting component 2 is installed on the installation seat 1, a movable block 3 is fixedly installed at the output end of the adjusting component 2, two ends of the movable block 3 are both hinged with connecting rods 4, and one ends of the two connecting rods 4, which are far away from the movable block 3, are both hinged with an eye speculum component 5;

the adjusting component 2 comprises a screw rod 21, an internal thread cylinder 22 and a grip 23; the internal thread cylinder 22 is rotatably arranged on the outer side of the mounting seat 1, the screw rod 21 penetrates through the internal thread cylinder 22 and is in threaded connection with the internal thread cylinder 22, one end of the screw rod 21 is fixedly connected with the movable block 3, and the other end of the screw rod 21 is fixedly connected with the handle 23; the outer side of the internal thread cylinder 22 is provided with a plurality of anti-slip threads which are uniformly distributed around the internal thread cylinder 22. The anti-slip threads are used to prevent slippage when turning the internally threaded barrel 22.

The working principle is as follows: when the eyelid retractor works, a medical worker holds the grip 23 with one hand and rotates the internal thread cylinder 22 with the other hand, so that the screw rod 21 and the internal thread cylinder 22 move relative to each other, the movable block 3 can be far away from the mounting seat, the two connecting rods 4 can open the two eyelid opening assemblies 5 outwards, and the two eyelid opening assemblies 5 rotate oppositely to open the eyes of a patient; the whole process is simple to operate, the two hands of the medical staff cooperate to ensure the overall stability, and the eyelid opening component 5 is prevented from shaking to cause discomfort to the patient.
