Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmology, in particular to an eyeball rotation measuring device. Background Art

[0002] When the human body changes from a sitting position to a lying position, the eye rotation caused by physiological activities such as vestibular reflex is called static eye rotation compensation; the eye rotation that occurs during laser cutting is called dynamic eye rotation compensation. Femtosecond laser small incision corneal stromal lens extraction, namely SMILE surgery, is currently the mainstream corneal refractive surgery method. However, SMILE surgery cannot control and measure eye rotation, in order to understand the situation of eye rotation. Therefore, it is necessary to design an eye rotation meter to measure whether the eye rotates in the lying position and sitting position during surgery, the direction and amount of rotation, and reduce the impact of eye rotation on SMILE surgery.

[0003] At the same time, in SMILE surgery, an incision with accurate positioning and size needs to be made on the cornea. Therefore, it is necessary to integrate the functions of positioning the incision and measuring the size of the incision on the eyeball rotation meter.

[0004] For example, the Chinese patent with publication number CN112043235A discloses a portable eyeball static rotation measuring instrument, which includes a high-definition infrared camera, an image processing module, an image acquisition button, an infrared light source and a visible light source, a test window and a wearable helmet. The high-definition infrared camera, image processing module, image acquisition button, infrared light source and visible light source, and test window are all arranged on the wearable helmet. The wearable helmet is arranged in the longitudinal direction, and the wearable helmet can be movably and detachably arranged in front of the user's eyes. The high-definition infrared camera is symmetrically arranged in the horizontal direction and arranged in the wearable helmet. The high-definition infrared camera can simultaneously capture the iris images of both eyes; an infrared light source and a visible light source are arranged between the two high-definition infrared cameras. However, the patent has a complex structure and is a wearable helmet. It is impossible to perform surgical operations when measuring eyeball rotation, and it is impossible to locate the incision and measure the size of the incision. Therefore, it is not suitable for SMILE surgery. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-5 As shown, an eye rotation measuring device is characterized in that it includes a frame 1, a ruler 2, a handle 3 and a marking point 4; the frame 1 is connected to the handle 3, the ruler 2 is fixed in the frame 1, and the marking point 4 is set on the frame 1.

[0028] The frame 1 is in the shape of a ring, and the inner diameter of the ring is 8 to 16 mm.

[0029] In this embodiment, the inner diameter of the frame 1 is 12 mm, which is suitable for most eyeballs.

[0030] The length of the ruler 2 is 1-3 mm.

[0031] Place the frame around the eyeball and use Ruler 2 to locate the desired incision for the SMILE procedure and Ruler 2 to measure the length of the incision.

[0032] In this embodiment, the ruler 2 is 2 mm long and is cut at a 90° angle on the cornea, with a length of 2 mm.

[0033] The length of the handle 3 is 6 to 15 cm.

[0034] According to the practice of the operator, the handle 3 can be selected to have a suitable length to effectively improve the efficiency of the operation. In this embodiment, the handle is 12 cm long.

[0035] The handle 3 and the ruler 2 are spaced 90 degrees apart along the arc of the frame 1 .

[0036] The handle 3 and the ruler 2 are arranged to be perpendicular to each other to prevent the handle 3 from blocking the user's sight when using the eyeball rotation measuring device, and thus preventing the ruler 2 from being used for accurate measurement. At the same time, it is also more in line with the user's grasping habits.

[0037] The handle 3 is provided with anti-slip textures.

[0038] The anti-slip texture enhances friction, making the eyeball rotation meter more stable and reliable.

[0039] The ruler 2 is provided with scale lines.

[0040] By measuring the incision length through the scale line, the incision can be cut smaller according to the actual situation.

[0041] The marking point 4 is V-shaped and is arranged below the frame 1 .

[0042] Medical ink is applied to the mark point 4. When the frame 1 is used to align the eyeball, the eyeball rotation measuring device is gently pressed down, and the mark point 4 will be marked on the cornea.

[0043] The marking points 4 include a first marking point and an angle marking point. The first marking point is arranged below the frame 1 where the ruler 2 is fixed, and the angle marking points are arranged on both sides of the first marking point.

[0044] In this embodiment, the ruler is aligned with the cornea at 90° to make an incision, and the first marking point will also be marked at 90° of the cornea.

[0045] When the eyeball rotates, the cornea is driven to rotate, and the mark also rotates. By comparing the mark with the original position, it can be known whether the eyeball has rotated, and the direction and amount of rotation.

[0046] The plurality of angle marking points are arranged at both sides of the first marking point at intervals of 10 to 90 degrees.

[0047] In this embodiment, there are two angle marking points, which are spaced 90° apart on both sides of the first marking point, that is, the angle marking points are marked at 0° and 180° of the cornea, and the first marking point is marked at 90° of the cornea.

[0048] The setting of angle marking points is helpful to determine the positive and negative directions of the marking points and assist in measuring eye rotation.

[0049] The utility model determines the incision position required in the SMILE operation by means of a frame and a ruler, and marks the cornea with marking points at the same time, and can measure whether the eyeball rotates according to the marks, thereby realizing the function of detecting eyeball rotation.

[0050] The handle is provided with anti-skid patterns to enhance friction, making the eyeball rotation measuring device more stable and reliable when used; the structural dimensions of each component are reasonably set, making it easy to use and making the measurement data simpler; the structure is simple and the cost is low.
