Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an eyeball positioning device and an ultrasonic biological microscope. Background Technology

[0002] Ultrasonic biomicroscopy (UBM) is an ultra-high frequency two-dimensional imaging method that can clearly display the structural features of the anterior segment and measure relevant parameters. It can provide quantitative analysis of changes in the anterior chamber angle morphology and help with changes in the anterior segment morphology before and after endoscopic eye surgery. Currently, in clinical application of UBM, the operator needs to hold the UBM probe in one hand and fix the eye cup placed in the patient's eye with the other, ensuring no leakage of fluid from the eye cup. However, some patients are unable to move their eyes independently, requiring the operator to release the probe and guide the patient's positioning using gestures or other methods, resulting in significant time and effort expenditure and increased patient discomfort. In clinical practice, besides patients who cannot accurately locate the 3, 6, 9, and 12 o'clock positions with their eyes, there are also patients with special reasons such as trauma who need to locate all 12 points, especially those with only light perception, who may not even be able to move their eyes according to the operator's guidance, making UBM measurements even more difficult. When the patient's eyes are constantly moving and unable to fixate on the positioning points, the operational difficulties for medical staff are greatly increased. Therefore, in order to meet clinical needs, this utility model aims to provide an eyeball positioning device to solve the above-mentioned technical problems. Utility Model Content

[0025] The technical solution of this embodiment will be clearly and completely described below with reference to the accompanying drawings. The embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Therefore, it should be understood that various modifications and changes can be made to this embodiment without departing from the scope of protection of this utility model.

[0026] In the description of this invention, unless otherwise expressly specified and limited, the term "and / or" includes any and all combinations of one or more of the associated listed items. Unless otherwise specified or stated, the terms "connection," "fixed," etc., should be interpreted broadly; for example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] Furthermore, in the description of this utility model, it should be understood that the directional terms described in this embodiment are used to describe the angles shown in the accompanying drawings and should not be construed as limiting this embodiment. It should also be understood that, in the context, when an element or feature is mentioned as being connected to another element (one or more), it can be connected not only directly to the other element (one or more) but also indirectly to the other element (one or more) through an intermediate element.

[0028] Before introducing the technical solution of this utility model, it is necessary to explain the background of its creation: Ultrasonic biological microscopy (UBM) is an ultra-high frequency two-dimensional imaging method that can clearly display the structural characteristics of the anterior segment and measure relevant parameters. It can provide quantitative analysis of changes in the morphology of the anterior chamber angle and help with changes in the morphology of the anterior segment before and after intraocular lens implantation surgery. Currently, in the clinical application of UBM, the operator needs to hold the UBM probe in one hand and fix the eye cup placed in the patient's eye with the other hand, while ensuring that the liquid in the eye cup does not leak. However, some patients are unable to cooperate in moving their eyeballs, so the operator has to release the probe and use gestures or other methods to guide the patient in positioning, which consumes a lot of time and energy and also increases the patient's pain. In clinical work, in addition to patients who cannot accurately locate the 3, 6, 9, and 12 o'clock positions with their eyes, there are also patients who need to locate all 12 positions with their eyes due to special reasons such as trauma, especially patients with only light perception, who may not even be able to move their eyeballs according to the operator's guidance, making UBM measurement work even more difficult. When the patient's eyeballs are constantly moving and they cannot fixate on the positioning points, it will also greatly increase the difficulty of operation for medical staff.

[0029] Please see Figures 1 to 3An exemplary embodiment of this utility model provides an eye positioning device. The eye positioning device of this utility model, installed on an ultrasonic biomicroscope probe, includes a fixing ring and a positioning ring. The fixing ring includes a fixing part 1 tightly fitted to the side wall of the ultrasonic biomicroscope probe, and a mounting part 11 located at the bottom end of the fixing part 1. The positioning ring includes an inner ring 2 securely connected to the mounting part 11, and an outer ring 3 rotatably connected to the inner ring 2. The surface of the outer ring 3 has a 12-point scale 4 along its circumference. Additionally, the surface of the fixing part 1 is provided with an indicator pin 5 for guiding the rotation of the patient's eyeball. It should be noted that the fixing part 1 is a rubber ring structure that is wider at the top and narrower at the bottom. This structure allows the fixing part 1 to fit tightly onto the ultrasonic biological microscope probe, and the fixing part 1 is elastic enough to be suitable for ultrasonic biological microscope probes of different sizes, effectively improving the applicability of this eye positioning device. The fixing part 1 and the mounting part 11 are designed as separate structures. For example, the fixing ring can be connected to the mounting part 11 by adhesive to form a fixing ring. The mounting part 11 is bolted to the inner ring 2 to achieve the connection between the fixing ring and the inner ring 2 of the positioning ring. The inner ring 2 rotates synchronously with the fixing ring and the ultrasonic biological microscope probe along the center of the outer ring 3. The indicator needle 5 will rotate with the fixing ring. The operator can use the 12 o'clock scale 4 on the outer ring 3 of the positioning ring for positioning, or perform more precise positioning description.

[0030] In some embodiments, please refer to Figure 1 and Figure 2 The indicator needle 5 includes a needle holder that is securely connected to the fixing part 1. The needle holder is equipped with indicator lights 54, a power supply 52, a switch 53, and several indicator lights 54 of different colors. The indicator lights 54 are evenly spaced along the length of the needle holder. Specifically, one end of the needle holder has a folded edge 51 for secure connection to the fixing part 1, and the other end of the needle holder extends horizontally away from the fixing part 1. That is, the needle holder is set perpendicular to the fixing part 1, providing an installation basis for the indicator lights 54 to effectively guide the direction and amplitude of the patient's eye movement. The needle holder is installed at the middle height position of the fixing part 1, and the needle holder is connected to the fixing part 1 by bolts. The bolt connection allows the indicator needle 5 to be easily removed for disinfection and storage.

[0031] In some embodiments, please refer to Figure 2The indicator lights 54 are connected in parallel. The operator can adjust the switch 53 of the required indicator light 54 according to the direction and amplitude of the patient's eye movement to guide the eye movement. In the above scheme, the power supply 52 of the indicator light 54 is installed at the bottom of the needle holder. The switch 53 and the indicator lights 54 of different colors are connected in parallel. The indicator lights 54 can illuminate as the patient's fixation point to ensure that the patient's eye does not move after rotating to the appropriate position. As a preferred technical solution, this eye positioning device includes four sets of indicator lights 54 arranged at equal intervals. By having the patient look at different colored lights, the patient's eye can be turned outward. The direction indicated by the pointer 5 is the direction of the patient's eye movement. The distance between the indicator lights 54 of different colors is different, which can change the amplitude of the patient's eye movement in that direction, thereby accurately meeting the examination requirements. Preferably, the colors of the four sets of indicator lights 54 are white, yellow, red, and green, so that the patient can clearly and accurately perform eye movement.

[0032] There are two connection methods for the inner ring 2 and the outer ring 3: In some embodiments, the inner wall of the outer ring 3 has a groove along the circumferential direction, and the outer wall of the inner ring 2 has a snap-fit ​​protrusion that mates with the groove. The outer ring 3 and the inner ring 2 are rotatably connected through the groove and the snap-fit ​​protrusion. In some other embodiments, the outer ring 3 and the inner ring 2 include a ball bearing 6 and a cage, meaning the positioning ring as a whole has a bearing-like structure. Figure 3 As shown, this is to achieve a rotatable connection between the outer ring 3 and the inner ring 2.

[0033] Based on the above-mentioned eye positioning device, this utility model also provides an ultrasonic biological microscope that uses the above-mentioned eye positioning device.

[0034] Reference Figures 1-3 Taking the preferred embodiment above as an example, the application method of this utility model is described as follows: First, the fixing ring is correctly installed on the ultrasonic biological microscope probe to ensure tight installation. The indicator needle 5 is installed in the horizontal opposite direction of the probe's sensing indicator point. During use, the patient looks at the corresponding indicator light 54. The light fixation point is adjusted according to the patient's eyeball abduction amplitude. The operator scans the image at each point according to the scale on the outer ring 3 of the positioning ring to obtain image development. Finally, the results are described based on the image development at different points.

[0035] In summary, the above-mentioned eye positioning device has the following technical advantages: 1. This eye positioning device is mainly for patients who cannot accurately and timely locate the 3, 6, 9, and 12 o'clock positions with their eyes, especially patients who need to locate all 12 positions due to special reasons such as trauma. The indicator needle can assist patients with only light perception in positioning and ensure that the patient's fixation point remains stationary. Different distances and colors of light can change the patient's eye abduction range, which helps the operator guide the patient to perform accurate positioning and examination. In addition, the fixing ring helps the examiner guide the patient to perform accurate positioning and accurate description of the examination results, and the operation is simple; 2. This eye positioning device can not only be used for eye positioning examinations under ultrasonic biological microscopes, but also for other ophthalmological examinations that require eye positioning measurements; 3. The eye positioning device of this invention is simple to install and disassemble, has low wear and tear, and can be wiped and disinfected routinely.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
