Description
Technical field
The utility model relates to ophthalmic medical instrument technical fields, specifically, being ophthalmostat in a kind of art, are used for
Fixation during ophthalmologic surgical procedures to eyeball, avoid because in art eyeball rotation due to caused by operating difficulties and operating time prolong
It is long.
Background technique
Eyeball is the important organs of vision of human body, is contacted by orbital fasciae, ligament and socket of the eye wall.Have six eyes on wall of eyeball
The rotary moveable of eyeball is adjusted in outer flesh.Peribulbar has Orbitalis fat pad, therefore, in terms of dissection level, due to eyeball and socket of the eye
Special structural relation between wall, eyeball, without fixed supporting point, are equivalent to " suspension " state in eye socket.The mobility and view of eyeball
Wild size is closely related, and mobility is bigger, and the visual field is bigger.Therefore, it is the requirement for meeting its visual performance, makes it have biggish
Mobility, the achievable multi-direction rotation of wide-angle.
In numerous ophthalmologic operations, if foreign body on cornea takes out, corneal lamellar operation, cataract operation, intraocular surgery etc.,
Corresponding operating need to be carried out in ocular or through ocular.As cataract operation makes scleral tunnel or deep lamellar keratoplasty plate layer point
From in the process, in the unlocked situation of eyeball, due to the activity of eyeball, and patient lacks fixed pivot, the eyeball in force
It can be rotated with force direction and cause operating difficulties.At present in ophthalmologic operation, ophthalmology tweezer is mainly used for the fixation of eyeball
The method for holding opposite side conjunctiva.This method has the disadvantage that 1. eye conjunctiva organizational slacks, and ocular movemeut degree is larger, due to eye
Section's tweezer clamping range is smaller, therefore this method can not fix eyeball very well, smaller for the auxiliaring effect of surgical procedure； 2.
Eye conjunctiva soft texture, brittleness is big, in ophthalmic surgical procedures, since ophthalmic tweezers are the sharp instrument of point, and fixes pursuing
The dynamics that eye conjunctiva is torn in clamping certainly will need to be increased in the case where effect.Therefore the eyeball fixing means easily damages eye conjunctiva,
Cause additional injuries.
Chinese patent CN201710373U discloses a kind of ophthalmostat, including elastic fastening belt and two eyeball covers,
Oblique clamp arm is equipped with clamp platform, and eyeball cover side is equipped with perforative opening, and elastic fastening belt runs through two by opening side by side
Eyeball cover, elastic fastening belt both ends are equipped with tightening device, and what which solved that patient's eyeball in CT scan do not rotate independently asks
Topic, using the tightening device of elastic fastening belt, can be adjusted, eyeball cover can be in elastic fastening belt according to patient head size
Upper sliding adjusts the distance of two eyeball covers according to the size of patient's interpupillary distance.When the ophthalmostat is regained consciousness mainly for patient
Eyeball does not rotate independently, to the fixation of eyeball when suitable for certain eye examinations, is not used in surgical procedure to eyeball
It is fixed.
Chinese patent CN103310681A discloses a kind of in-vitro eyeball fixator, including ice chest, irrigation drainage tube, rectus
Fixing piece, the groove for being set in the ice chest and matching with eyeball shape to be placed are equipped with conduction hole in bottom portion of groove, described
Irrigation drainage tube one end is connected to the conduction hole, and the other end is pierced by from ice chest bottom, the rectus fixing piece with it is to be placed
The rectus distributing position of eyeball is correspondingly set to the outside of the groove notch edges, and make rectus fixing piece with it is to be placed
The attachment point of the rectus of eyeball is consistent with the horizontal plane of the in-vitro eyeball fixator.The in-vitro eyeball fixator be suitable for from
Body eyeball, for not being available in body eyeball.
Currently, clinically there are no can be individually used for the instrument that eyeball is fixed in art.Therefore, difficult to reduce surgical procedure
Degree shortens operation time, needs exploitation and designs a kind of instrument that can be used in ophthalmologic operation being auxiliarily fixed eyeball, and current
It is had not been reported about this instrument.
