Embodiment Construction

[0035] The present invention will be further described below in conjunction with the examples.

[0036] Figure 1-Figure 12 It is an embodiment of a corneal astigmatism loosening aid in the present invention, which includes an external fixation ring 1, an operating handle 2 and a sliding knife groove assembly 3. The shape of the external fixation ring 1 is circular or semi-circular, circular The unique design can facilitate the positioning and operation of various angles and positions. The semi-circular design and the observation window in the semi-circular gap can avoid occlusion, and it is convenient to observe the positioning position from the semi-circular gap, and the operation is more convenient. , fast.

[0037] The upper surface of the outer fixed ring 1 is provided with an axial dial 101, the axial dial 101 includes scale lines and angle scales, the width of the axial dial 101 is 2±0.1 mm, and the inner ring diameter of the axial dial 101 is 11 mm. ±0.5mm, the middl...

Abstract

The present invention provides a corneal astigmatism release assistor which comprises an outer fixing ring, an operating handle and a sliding cutter groove assembly, an axial position dial is arranged on the upper surface of the outer fixing ring and comprises scale marks and angle scales, an outer ring sliding groove is formed in the middle of the outer fixing ring, a cutter groove adjusting opening is formed in the outer ring side surface of the outer fixing ring, the cutter groove adjusting opening is communicated with the outer ring sliding groove, and an included angle is formed between the lower surface of the outer fixing ring and the horizontal plane. The lower surface of the outer fixing ring of the device is an eyeball-imitating surface, so that the device can stably contact with an eyeball, the structural design of the axial position dial can accurately position an astigmatism axial position and the starting end of a cornea incision, the sliding knife groove assembly can slide and can stabilize the radian and depth of the cornea incision, the assistor can ensure that the incision is regular, round and regular in shape and fixed in depth, and the postoperative effect is ensured. The assistor can be widely applied to corneal astigmatism release operations.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a corneal astigmatism loosening aid. Background technique [0002] Cataract is the most common blinding eye disease in the world. With the development of economy and technology, cataract patients have higher and higher requirements for postoperative visual quality and uncorrected vision. , also demanded durability, comfort, and mirror-free status. Preoperative corneal astigmatism is an important factor leading to poor postoperative vision in cataract patients. Modern manipulative limbal release is economical, simple and safe, and has good effects in correcting moderate to low corneal astigmatism. It is a surgical technique that is very suitable for popularization. [0003] However, this surgical approach requires the assistance of a device that accurately marks the location of corneal astigmatism and controls the depth of the corneal incision. In the past, for corneal ...
