Description
Technical field
The utility model relates to training aids, specifically a kind of external suitable for the elderly and ptosis patient
Eye speculum.
Background technique
Eye speculum is essential medical instrument in a kind of ophthalmologic operation and eye operation, and working principle is similar to outer
Indispensable tool --- the drag hook of section's operation plays the role of expanding eyelid, exposure visual area, so referred to as eye speculum.
In the inspection of ophthalmology retinal disease and treatment, examiner is high to the fitness requirement of patient.Usually need
It opens eyes wide, sufficiently exposes pupil, so as to doctor's observing eye bottom overall picture or acquisition is complete and clearly eye fundus image.It encounters
On patient's fissura palpebrae is too small, the young fitness of patient is poor, the sagging or Patients With Myasthenia Gravis of the larger upper eyelid relaxation of patient age has
When ptosis situation, doctor can only do it yourself that patient is helped sufficiently to expose pupil.But it needs to grasp on the other hand when oculist checks
The other hand need to hold preset lens when making slit-lamp, and checking eyeground, it is sometimes desirable to eye speculum auxiliary.In addition, on many eyeground
Check, such as micro- visual field, optical coherence tomography, fluorescence fundus angiography need for a long time sufficiently exposure pupil, with shoot
Eye ground or alignment eyeground a part carry out functional assessment, require height to the abundant degree of exposure of patient s pupil, and exposure duration is long,
And usually across huge instrument and equipment between operator and patient, patient is helped to cause larger difficulty operator, and patient
How self-service I and family members are often ignorant of.Strut upper and lower eyelid by force even with eye speculum, it also can be because transferring to make to examine on eyeball
Looking into light source can not inject intraocularly, be unable to complete inspection, or inspection is interrupted because of ophthalmic uncomfortable.Therefore it usually needs to be equipped with another doctor
Business personnel auxiliary, causes the waste of human resources.
Current clinically used eyelid mode of opening has two kinds: one is metal eye speculums, including the common spring of outpatient service to open
The spiral eye speculum of fissura palpebrae openness is commonly adjusted in eyelid device and operating room.Its advantage is that easy to operate, time saving.Drawback is main
Have the following aspects: 1. both belong to built-in eye speculum, need to be placed in eye speculum both ends in the upper palpebra inferior of patient, use
Before need local anaesthesia, and while being placed in, may be resisted, relatively time consuming；2. spring eye speculum is unstable, can be resisted because of patient
And it automatically springs open；3. after opening eyelid, patient's eyeball easily because hide light source or open eyelid it is excessive due to go up turn, especially spring is opened
Eyelid device to open eyelid degree larger and fixed, cause to be unable to fully light source of being checked；4. lower eyelid is softened on, the review time compared with
When long, patient can not twinkle, and the rupture of corneal exposure overlong time tear film is easy to cause corneal injury, cause patient uncomfortable.5. this
It needs to carry out autoclaving sterilization processing after two kinds of metal eye speculum uses, cross-infection is avoided, if examiner is more to be faced
The predicament of eye speculum insufficient supply.Another kind is that suture opens eyelid, but complicated for operation, time-consuming, and fissura palpebrae hour also needs to make outer to adjoin incision
Art.
With the propulsion of aging of population process, the rising of age related retinopathy disease incidence and people want visual function
The increasingly raising asked, ophthalmology outpatient service need to more and more carry out the elderly of eyeground coherence check by welcoming.Therefore it urgently improves
A kind of eye speculum suitable for the elderly and ptosis patient out, the medical experience and doctor for improving such crowd are such people
The efficiency that group checks.
