Description

Technical Field

[0001] This invention relates to the field of medical ophthalmic instruments, and in particular to an eyelid opener that can be fixed to an ophthalmic examination instrument and its application. Background Technology

[0002] In ophthalmological clinical examinations, many core procedures, such as slit-lamp examination, intraocular pressure measurement, corneal topography, and fundus photography, require patients to keep their eyes open throughout the examination to obtain clear images and accurate test data. However, for subjects with low cooperation levels, such as those with eye sensitivities, dry eye syndrome, photophobia, and young children, maintaining an open-eyed state for extended periods is extremely difficult.

[0003] In clinical practice, for the above-mentioned groups, it is often necessary to wait for the patient to adjust their state repeatedly and try multiple times to complete the examination. This not only significantly prolongs the examination time for a single patient and reduces the efficiency of ophthalmology clinic visits, but also makes it very easy for the instrument to make mistakes in the detection data and blur the image due to the patient blinking or moving their eyeballs during the examination. Multiple examinations are required to obtain valid results.

[0004] CN200920155789.2 discloses an eyelid speculum, including a support with a protrusion that can be placed flat beside the eye without being affected by the bridge of the nose. The support has a reinforcing ring for further stability. The support has a spring for fixing a tube and a button spring at one end in a U-shaped section below a bushing. The bushing contains a connecting rod with an eyelid-pulling hook. The connecting rod has a V-shaped protrusion that can open the eyelid at any time, but the button spring must be pressed to close the eyelid. The end of the connecting rod has a screw and nut for fixing the rectus muscle suture, and the rectus muscle fixing suture can be clamped between two layers of nuts. Accessories include an eyeball fixation bracket, a corneal lens bracket, and a panretinal lens bracket. Fixed to the eyelid speculum bracket, it can fix the eyeball and place a corneal lens or panretinal lens. However, the structure is complex and cannot be integrated with examination instruments.

[0005] Current clinically used eyelid openers are mostly forceps-like structures with hand handles, requiring medical staff to manually hold and hold the patient's eyelids open. However, this type of structure has significant technical drawbacks: firstly, hand-held operation is easily affected by hand tremors, and the protruding handle structure is prone to spatial interference with the detection end of ophthalmic examination instruments. It is also severely limited by instrument size and examination distance, making it impossible to stably maintain the eyelid open state while the instrument is being used for examination. Secondly, hand-held operation requires medical staff to maintain a fixed posture throughout the process, significantly increasing the workload and making it impossible to synchronize with the instrument examination process, thus failing to fundamentally solve the problems of low examination efficiency and repetitive operations. Therefore, there is an urgent need to develop an eyelid opener that overcomes the above-mentioned defects, is compatible with ophthalmic examination instruments, and can stably open the eyelids during examination, thereby improving the efficiency of ophthalmic examinations and patient comfort. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects of the prior art and provide an eyelid opener that can be fixed to an ophthalmic examination instrument and its application, thereby improving examination efficiency and ease of operation, with strong adaptability, high safety and simple structure.

[0007] The objective of this invention can be achieved through the following technical solutions: This invention provides an eyelid opener that can be fixed to an ophthalmic examination instrument, comprising an eyelid opening component and an instrument fixing component that are connected to each other; The eyelid opening assembly is used to open the patient's upper and lower eyelids; the eyelid opening assembly includes an upper eyelid hook, a lower eyelid hook, and an elastic adjustment element, the elastic adjustment element being used to connect the upper eyelid hook and the lower eyelid hook; One end of the instrument fixing component is detachably connected to the ophthalmic examination instrument, and the other end of the instrument fixing component is connected to the eyelid opening component via a telescopic rod; the center of the eyelid opening component is coaxial with the center of the detection optical path of the ophthalmic examination instrument.

[0008] Furthermore, the ends of both the upper and lower eyelid hooks are rounded arc-shaped structures.

[0009] Furthermore, the elastic adjustment element is used to adjust the opening amplitude according to the patient's palpebral fissure width.

[0010] Furthermore, the elastic adjustment member includes a slot and a slider that can move in the slot, and the slider can be screwed and fixed in the slot.

[0011] Furthermore, the elastic adjustment element provides an eyelid opening range of 8mm to 18mm.

[0012] Furthermore, the eyelid opening assembly is magnetically connected to the telescopic rod, making it easy to install and remove.

[0013] Furthermore, the instrument fixing assembly includes a clamping component and an adjusting component for fixing the clamping component, the adjusting component being capable of adjusting the radial dimension of the clamping component.

[0014] Furthermore, the adjusting component is a threaded bolt structure provided on the clamping component.

[0015] Furthermore, the instrument fixing assembly can be matched with the detection end of ophthalmic examination instruments with an outer diameter of 15mm to 40mm.

[0016] The present invention also provides an application of an eyelid opener that can be fixed to an ophthalmic examination instrument, which can be used in slit-lamp examinations, non-contact intraocular pressure measurements, corneal topography examinations, or fundus photography examinations that require the patient to keep their eyes open.

[0017] The ophthalmic examination instruments include at least one of the following: slit lamp, non-contact tonometer, corneal topography instrument, and fundus camera.

[0018] The eyelid retractor assembly is made of medical-grade 304 stainless steel or medical-grade polycarbonate. The surface roughness Ra of the eyelid retractor assembly is ≤0.8μm, its biocompatibility meets medical device standards, and it can withstand high-temperature and high-pressure sterilization.

[0019] The preparation method of the eyelid opener includes the following steps: According to the design drawings, the base material including the eyelid opening component and the instrument fixing component is integrally formed by machining, and the end of the eyelid hook of the eyelid opening component is rounded. The processed substrate is finely polished to remove surface burrs and sharp edges; The polished substrate is ultrasonically cleaned and sterilized under high temperature and high pressure to obtain the finished eyelid opener.

[0020] Compared with the prior art, the present invention has the following advantages: (1) Improved examination efficiency and ease of operation. The eyelid opener is directly integrated with ophthalmic examination instruments (such as slit lamps and tonometers) through the instrument fixing component, eliminating the need for medical staff to operate it by hand throughout the process. This completely avoids the problems of hand tremors and spatial interference with the instrument, allowing the eyelid opening operation to be fully synchronized with the examination process, thereby significantly shortening the examination time for a single patient. It solves the pain point of traditional eyelid openers requiring repeated adjustments and resulting in multiple repeated examinations, and improves the efficiency of ophthalmology clinics.

[0021] (2) High adaptability and wide range of applicable scenarios. The instrument's fixing components adopt an adjustable design, which can be adapted to a variety of mainstream ophthalmic examination equipment on the market, including slit lamps, non-contact tonometers, corneal topography instruments, fundus cameras, etc. This wide adaptability enables it to meet the needs of most ophthalmology clinic examination scenarios that require patients to keep their eyes open, realizing "one instrument for multiple uses".

[0022] (3) High safety, meeting clinical medical standards. The eyelid opener is made of medical-grade biocompatible materials (such as 304 stainless steel or polycarbonate). Its structural design (especially the end of the eyelid hook) is smooth and without sharp edges, and the surface is finely polished, which can completely avoid scratching the patient's cornea, eyelids or conjunctiva during the operation. At the same time, the product can withstand routine high temperature and high pressure sterilization treatment in clinical practice, is safe and reliable, and can be reused. It reduces the requirements for patient cooperation and improves the comfort of the examination. The eyelid opening component stably fixes the patient's upper and lower eyelids, so the patient does not need to rely on their own willpower to keep their eyes open for a long time.

[0023] (4) Simple structure, easy to scale up production and promote clinical application. The integrated design eliminates the complex transmission structure and independent handheld components, resulting in a simple and reliable overall structure. This makes its processing and production process relatively simple, production costs controllable, and easy to scale up production. It is suitable for popularization and promotion in ophthalmology clinics, ophthalmology hospitals, and physical examination centers at all levels of hospitals. Attached Figure Description
