Description

Cornea marker

Technical Field

The embodiment of the utility model provides a relate to medical equipment technical field, concretely relates to cornea marker.

Background

At present, a large number of patients with corneal blindness exist nationwide, the patients are the main blinding eye diseases, and corneal transplantation is one of the most effective treatment methods. In the corneal transplantation operation, a corneal marker is used for determining the range of focus of surgical excision and the position of suture. The cornea marker used in clinic at present is a regular circle with different diameters, is suitable for focus in the center and the lateral center of the cornea, and is not suitable for lesions of other anatomical parts of the cornea, such as marginal corneal degeneration and expansion, marginal corneal ulcer, sericultural corneal ulcer, peripheral corneal tumor and the like. At present, doctors do free-hand demarcation during the operation of the diseases, the shape is not easy to control, irregular astigmatism is caused after the operation, and the operation time is long.

SUMMERY OF THE UTILITY MODEL

Therefore, the embodiment of the utility model provides a cornea marker to solve among the prior art because when the doctor demarcated patient's focus position through bare-handed, the difficult shape of controlling and lead to the problem of postoperative irregular astigmatism.

In order to achieve the above object, the embodiment of the present invention provides the following technical solutions:

according to the utility model discloses an aspect a cornea marker, including inner ring piece and outer ring piece, be fixed with a plurality of radial connection wings that are on the outer wall of inner ring piece, a plurality of connection wing circumference equipartitions are to the inner ring piece, every the lower extreme of connecting the wing is fixed respectively to the edge of outer loop on, still be fixed with the connection handle on the outer wall of inner ring piece.

Furthermore, the connecting wing is of an arc-shaped sheet structure.

Further, eight connecting wings are arranged.

Furthermore, the diameter of the inner ring piece is 7.5mm, 6.5mm or 5mm, the diameter of the outer ring piece is 12.5mm, and the ring width is 2.5mm, 3mm or 3.5 mm.

Further, an alloy gripping handle is arranged at the end part of the connecting handle.

The embodiment of the utility model provides a have following advantage: through the setting of inner ring piece, outer ring piece, connection wing and connection handle, can be according to the state of an illness during the use, including the coating of marking fluid on the edge of ring piece and outer ring piece and the edge of connection wing, later handheld connection handle, slightly press the focus position of inner ring piece and outer ring piece orientation eye, just so can clearly show the peripheral focus that the operation needs to be amputated, it transplants the operation into regular peripheral cornea with irregular cornea, the operation in the doctor's art of being convenient for, in addition through the setting of the inner ring piece and the outer ring piece of different kinds of specifications, can treat the patient of eye focus variation in size.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below. It should be apparent that the drawings in the following description are merely exemplary, and that other embodiments can be derived from the drawings provided by those of ordinary skill in the art without inventive effort.

Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

A cornea marker is shown in figures 1 and 2 and comprises an inner ring piece 1 and an outer ring piece 2, wherein the inner ring piece 1 is positioned above the outer ring piece 2, a plurality of connecting wings 3 which are radial are fixedly connected to the outer wall of the inner ring piece 1, each connecting wing 3 is fixed to the lower end of the outer wall of the inner ring piece 1, the plurality of connecting wings 3 are uniformly distributed on the outer wall of the inner ring piece 1 in a circumferential mode, the lower end of each connecting wing 3 is fixed to the edge of an outer ring respectively, and a connecting handle 4 is fixedly connected to the outer surface of the inner ring piece 1.

When the cornea grafting instrument is used, marking liquid can be coated on the edges of the inner ring piece 1 and the outer ring piece 2 and the edges of the connecting wings 3, then the connecting handle 4 is held by hands, the inner ring piece 1 and the outer ring piece 2 are lightly pressed towards the focus part of the eye, so that the peripheral focus needing to be cut off in the operation can be clearly displayed, irregular cornea transplantation is converted into regular peripheral cornea transplantation operation, the operation in the doctor operation is facilitated, the operation time is greatly shortened, the operation incision is more regular, and the postoperative vision is better improved.

The connecting wing 3 is in an arc-shaped sheet structure, so that the shape of the connecting wing 3 is relatively fit with the shape of the focus part of the eye, and after the connecting wing is pressed on the focus part, marking can be conveniently carried out according to various disease conditions involving different peripheral corneas. In addition, the eight connecting wings 3 are arranged, so that the focus part can be fully divided into a plurality of areas for marking through the arrangement of the eight connecting wings 3, and the treatment difficulty is relatively reduced.

The diameter of the inner ring piece 1 is 7.5mm, 6.5mm or 5mm, the diameter of the outer ring piece 2 is 12.5mm, the ring width of the outer ring piece 2 is 2.5mm, 3mm or 3.5mm, wherein the ring width is a value obtained by subtracting the inner circle radius from the outer circle radius of the outer ring piece 2, and the corneal markers of different specifications can be used for marking when focal parts of patients with different eyes are pressed.

Wherein the end part of the connecting handle 4 is fixedly connected with an alloy gripping handle 5, and the arrangement of the alloy gripping handle 5 is convenient for the medical staff to grasp the cornea marker stably, so as to avoid the cornea marker from sliding to a certain extent on the handle to cause certain damage to the eyes of the patient.

The utility model discloses an inner ring piece 1, outer ring piece 2, connect wing 3 and connection handle 4's setting, can be according to the state of an illness with mark liquid coating at the edge of inner ring piece 1 and outer ring piece 2 and connect wing 3's edge during the use, later handheld connection handle 4, gently press inner ring piece 1 and outer ring piece 2 towards the focus position of eye, just so can clearly show the peripheral focus that the operation needs to be amputated, transplant irregular cornea and change into regular peripheral cornea and transplant the operation, operate in the doctor's art of being convenient for, in addition through the inner ring piece 1 of different kinds of specifications and outer ring piece 2's setting, can treat the patient of eye focus variation in size.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
