Description

Multipurpose cornea marker for cataract surgery

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a multipurpose cornea marker for cataract surgery.

Background

At present, a large number of cataract patients with combined corneal astigmatism exist in ophthalmology clinic, and the cataract surgery combined with the astigmatism correction type artificial lens is the most effective treatment means at present. Prior to the surgical implantation of an astigmatic lens in cataract, the patient is required to define the position of the horizontal axis of the cornea using a corneal marker in a conventional sitting position. However, the cornea markers used in clinic at present have the following problems:

1. the cornea marker has no centering structure, and whether the cornea marker is centered accurately can be judged only by feeling and experience, so that the marking has errors.

2. When marking the horizontal axis of the cornea, it is difficult to determine whether the marker is horizontal, and the marking of the horizontal axis of the cornea is inconvenient.

Therefore, how to solve the above technical problems becomes a focus of research by those skilled in the art.

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

1. the utility model coats the marking liquid on the stainless steel wire, the centering ring is close to eyes under the condition that a patient is in a sitting position, eyeballs can be observed in an enlarged mode through the convex lens, when the center of the pupil is covered by a black point, centering is proved to be completed, then the marker is kept horizontal by the level gauge, the level marking is completed on the eyeballs by lightly pressing the handle, and the whole level marking process is convenient and rapid.

2. The utility model can also smear marking liquid on the centering ring, then hold the connecting handle by hand, lightly press the centering ring towards the focus part of the eyes, thus clearly displaying the peripheral focus which needs to be cut off in the operation, and converting irregular cornea transplantation into regular peripheral cornea transplantation operation, and the instrument has multiple purposes.

3. The whole marking process can quickly complete centering, the operation is convenient, the centering accuracy is high, and the efficiency is also obviously improved.

Detailed Description

The utility model will be further described with reference to specific embodiments and the accompanying drawings.

Referring to fig. 1, the embodiment discloses a multipurpose cornea marker for cataract surgery, which comprises a centering ring 1, wherein a stainless steel wire 2 is integrally formed at the lower end edge of the outer side wall of the centering ring 1, the stainless steel wire 2 is of an arc-shaped structure, and the tail end of the stainless steel wire 2 is polished into a smooth blunt end to prevent an eyeball from being scratched. The outer wall of the centering ring 1 is further provided with a handle 7, the handle 7 comprises a handle 703, a handle rod 702 and a Z-shaped connecting rod 701, the connecting rod 701 is connected with the centering ring 1 and the handle rod 702, the handle 703 is arranged at the end of the handle rod 702, the Z-shaped connecting rod 701 is connected with the centering ring 1 and the handle rod 702, the handle rod 702 is lifted by a certain distance, and therefore when the centering ring 1 and the outer ring are close to an eyeball by using the handle rod 702, the handle rod 702 cannot cause obstruction, and the operation is convenient. The anti-skid texture is arranged on the handle 703, so that the operation by holding the handle 703 is facilitated. In addition, a groove is arranged on the handle 702, and a level 9 is arranged in the groove.

The inner ring of the centering ring 1 is provided with a ring plate 3, the ring plate 3 is provided with a step through hole, a picture frame 4 is detachably mounted in the step through hole, a convex lens 5 is mounted in the picture frame 4, and an opaque black spot 8 is arranged at the center of the convex lens 5. Rotatable pressing strips 6 are symmetrically arranged on the two sides of the surface of the ring plate 3, which are positioned at the step through holes, and the pressing strips 6 are pressed on the surface of the mirror frame 4.

From the above, the present embodiment discloses a multi-purpose corneal marker for cataract surgery, which is used in the following method:
