Technical Field

[0001] The invention relates to the medical field, in particular to a device for practicing retinal laser surgery. Background Art

[0002] Retinal laser photocoagulation is a commonly used ophthalmic treatment method that uses the thermal effect of laser to form photocoagulation spots on the retina and is used to treat a variety of fundus diseases.

[0003] The doctor's proficiency in this operation is a key factor in ensuring the treatment effect, and its results directly affect the patient's disease prognosis. At present, after doctors have learned the theoretical knowledge of fundus laser treatment, there is no retinal laser photocoagulation eye model that can be used for practical training. Summary of the invention

[0004] The present invention provides an eyeball model for practicing retinal laser surgery. The technical problem to be solved is: after doctors have mastered theoretical knowledge, how to provide an eyeball model for doctors to practice, so as to improve their practical operation skills.

[0012] Furthermore, the sclera and the lower sclera are respectively fixedly provided with a second rod and a first rod at positions away from the cornea;

[0013] After the sclera and the lower sclera are assembled, a clamping structure is provided on the contact surface of the second rod and the first rod.

[0014] Furthermore, a support frame is included, and the support frame is used to fix the eyeball model;

[0015] The support frame includes a fixed rod and an adjustment bracket;

[0016] The fixing rod is fixedly arranged vertically;

[0017] The adjusting bracket comprises a first locking bolt, an adjusting bracket, a sliding sleeve, a connecting rod, a mounting sleeve, and a second locking bolt;

[0018] The sliding sleeve is slidably inserted into the outer side of the fixed rod;

[0021] The mounting sleeve is used to place the eyeball model.

[0022] The beneficial effects of the present invention are:

[0023] Since the retina 60 is a photosensitive material, doctors can use fundus laser machines to leave laser marks on the photosensitive material, which can assist doctors in practical exercises. Therefore, an eyeball model is provided for doctors to practice, thereby improving their practical skills. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0032] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0033] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] First, a brief introduction to retinal laser surgery: (1) The structure of the eyeball. The outer layer of the eyeball is composed of the cornea and sclera. From the direction of the eyeball receiving light, from the outside to the inside, it is mainly composed of the cornea, iris, ciliary body, vitreous body, and retina; the retina is located between the vitreous body and the sclera. (2) Surgical operation. The laser machine emits lasers of a specific wavelength, which can penetrate the cornea, lens, and vitreous body of the eyeball and be absorbed by the retinal pigment epithelial cells. The thermal effect of the laser denatures and solidifies the retinal tissue protein, thereby achieving the treatment purpose.

[0035] Referring to the accompanying drawings, a device for practicing retinal laser surgery includes an eyeball model; the eyeball model includes a sclera 10, a cornea 20, an iris 30, a lens 40, a vitreous body 50, and a retina 60;

[0036] The shapes and positional relationships of the sclera 10 , cornea 20 , iris 30 , lens 40 , vitreous body 50 , and retina 60 are the same as those of a real eyeball.

[0037] The retina 60 is a photosensitive material. During the retinal laser surgery practice, the fundus laser machine can leave a laser mark on the photosensitive material, thereby assisting the doctor in the practical practice.

[0038] In summary, since the retina 60 is a photosensitive material, doctors can use fundus laser machines to leave laser marks on the photosensitive material, which can assist doctors in practical exercises. Therefore, an eyeball model is provided for doctors to practice, thereby improving their practical skills.

[0039] Furthermore, the photosensitive material is photosensitive paper; in addition, the photosensitive paper marks the shape of blood vessels, the optic disc and the macula. The photosensitive paper is disposable and replaceable, which is convenient for users to draw different lesion marks (representing different diseases) by themselves.

[0040] Furthermore, the sclera 10 is divided into two halves, namely, an upper sclera 12 and a lower sclera 11 .

[0041] Furthermore, the sclera 12 and the lower sclera 11 are respectively fixedly provided with a second rod 121 and a first rod 111 at positions away from the cornea 20;

[0042] After the sclera 12 and the lower sclera 11 are assembled, a clamping structure is provided on the contact surface of the second rod 121 and the first rod 111 .

[0043] In summary, since the sclera 12 and the lower sclera 11 are detachable, the old retina 60 can be taken out and replaced with a new retina 60 .

[0044] Furthermore, a support frame 80 is included, and the support frame is used to fix the eyeball model;

[0045] The support frame 80 includes a fixing rod 81 and an adjusting bracket 82;

[0046] The fixing rod 81 is fixedly arranged vertically.

[0047] The adjusting bracket 82 includes a first locking bolt 821, an adjusting bracket 82, a sliding sleeve 822, a connecting rod 823, a mounting sleeve 824, and a second locking bolt 825;

[0048] The sliding sleeve 822 is slidably sleeved on the outer side of the fixed rod 81;

[0049] The first locking bolt 821 is threadedly connected to the sliding sleeve 822 , and the first locking bolt 821 can tighten the fixing rod 81 .

[0050] One end of the connecting rod 823 is fixedly connected to the sliding sleeve 822; the other end of the connecting rod 823 is fixedly connected to the mounting sleeve 824;

[0051] The eyeball model can be placed in the mounting sleeve 824.

[0052] The position of the eyeball model can be adjusted using the support frame 80 .

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
