Description

The utility model relates to medicine, namely ophthalmology, and can be used to practice gonioscopy skills by resident doctors.

Today, the leading cause of blindness in the world is glaucoma; for the correct diagnosis and interpretation of the pathology of the anterior chamber angle, many demands are placed on ophthalmologists.

Unfortunately, the skill of mastering the gonioscopy technique is difficult to master, and the situation of joint training “on each other” may not always be appropriate, since after using a viscous substance, the assistant may notice temporary blurred vision, so his further work is difficult.

The applicant does not know the closest analogues of devices for practicing gonioscopy skills.

The objective of the invention is to create a device for practicing gonioscopy skills.

The technical result is the acquisition of gonioscopy skills with interpretation of the study results by resident doctors.

The technical result is achieved by the fact that the device for practicing gonioscopy skills is a transparent hemisphere, hollow inside, with a flat base with a diameter of 11 mm (1), a height of 3 mm (2). On the base, on the inside of the device, there is a schematic image of the iris (3), and in the center there is an image of the pupil (4). Schematically, along the circumference of the base on the inside of the device, the following areas are depicted: from 12 o'clock to 3 o'clock - the open angle of the anterior chamber, where 5 - Schwalbe's line, 6 - trabecula, 7 - Schlemm's canal, 8 - scleral spur, 9 - processes of the iris; from 3 o'clock to 6 o'clock - closed angle of the anterior chamber (10); from 6 a.m. to 9 a.m. - stage 4 pigmentation of the anterior chamber angle (11); from 9 a.m. to 12 p.m. - coagulates on the trabecula after laser trabeculoplasty (12). The thickness of the walls of the device is 1 mm, the device is made of polyvinyl chloride.

The utility model is illustrated in Fig. 1-6. In fig. Figure 1 schematically shows a device for practicing gonioscopy skills. In fig. 2 schematically shows the inner side of the base. In fig. Figure 3 schematically shows the open angle of the anterior chamber. In fig. Figure 4 schematically shows the closed angle of the anterior chamber. In fig. Figure 5 schematically shows the 4th degree of pigmentation of the anterior chamber angle. In fig. Figure 6 shows coagulates on the trabecula after laser trabeculoplasty.

Operation of the device is illustrated by the following example. The training procedure takes place in a darkened room. The examination is performed using a slit lamp and a gonioscopy lens. A viscous substance, carbomer gel, is placed on the inner surface of the lens, no more than half the plane. The device is located at the eye level of the intended patient, at the level of the slit lamp head support, with the base facing the assistant. The assistant holds the device for practicing the gonioscopy skill motionless. The lower part of the lens is placed on the device, then quickly and carefully pressed against the device to fully practice the gonioscopy skill. The gonioscopy lens is positioned so that its smaller convex mirror is located at 12 o'clock. The student, having received a binocular image, centers his gaze on the small convex mirror in the gonioscopy lens. Next, the width of the slit beam is set to 2 mm, and the beam axis is positioned at a right angle. The gonioscopy lens is then rotated clockwise. The study results are being interpreted.

This device allows you to practice gonioscopy skills.
