Eye surgery training simulator

Abstract

The invention provides an eye surgery training simulator. The eye surgery training simulator is advantageous in that the learning costs can be reduced, the simulation is closer to the real state of the eyes, the practice of the performer can be facilitated, and the surgery success rate can be increased. The surgery training simulator comprises a seat body provided with an accommodation groove body; a hollow ball body, which is disposed in the accommodation groove body, is provided with a penetrating hole in the central part of the top end, and is capable of simulating rotation of an eyeball; a thin film sheet body, which is disposed on the penetrating hole in the hollow ball body in a covered manner, and is capable of simulating a front anterior capsule; a positioning sheet body, which is attached to the top surface of the hollow ball body, is disposed on the thin film sheet body in a covered manner at the same time, is provided with a hole corresponding to the penetrating hole, and can be attached repeatedly; a positioning inserting member, which is disposed next to the penetrating hole, and is capable of limiting displacement of capsule tearing tweezers; and at least one elastic assembly, which is used to simulate the eyeball muscle, is used for the traction of the hollow ball body, and is used to reset the hollow ball body after the rotation.

Description

technical field [0001] The invention relates to an eye surgery training simulator, in particular to a simulator that enables ophthalmologists to practice continuous circular capsulorhexis surgery. Background technique [0002] The function of the eye is to provide vision by transmitting light through a transparent exterior called the cornea, and focusing the image onto the retina by a crystalline lens; the quality of the focused image is affected by many factors, including the size and shape of the eye, And the transparency of the cornea and lens; when the lens becomes cloudy or even hardened and less transparent due to aging, ultraviolet damage or other factors, it will prevent light and images from being transmitted to the retina, resulting in blurred vision, which means suffering from cataracts. [0003] The reason that causes cataract is multiple, can't be treated with single liquid medicine, can only delay the speed that cataract carries out at best, so far, operation i...

Problems solved by technology

[0004] Clinically, it is difficult to distinguish the edge of the capsulorhexis in the operation of mature and overmature senile cataract and some congenital cataracts, traumatic cataracts, nuclear cataracts, etc., so it is quite difficult to complete a standard CCC. Difficulty, this is because during cataract surgery, an incision will be made on one side of the transparent cornea for subsequent operations. With the continuous advancement of medical technology, the position of the incision has shifted from the sclera to the cornea. The size has gradually shrunk from the previous 12mm, 6mm, 3 to 3.5mm to the current 1.8 to 2.2mm, and it is difficult to perform CCC actions in such a small range.

[0005] Therefore, operators must often carry out simulation training of cataract surgery, so as to improve the success rate of CCC surgery, and the current simulation training method is mainly to perform operation training on artificial eyes or animal eyes, but this training method Not only is the cost high and the operation is inconvenient, but it also takes a long time to train to the level of being able to perform operations on patients. More importantly, after the training is completed, repeated practice and exposure are still
