Specific embodiment:

In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality It is described in detail with novel.

The embodiments of the present invention is as shown in Figs 1-4, vitreous chamber infusion eyeball fixture, comprising: patch 1, there is the negative camber being bonded with eyeball surface, pupil region 2 is equipped in the middle part of the patch 1；Two eyelid support portions 3, if Be placed in one side opposite with the negative camber on the patch 1, be respectively arranged at the two sides of the pupil region 2, with it is corresponding Eyelid abuts at position；Rib 4 is set between the two eyelids support portion 3, to limit two eyelids to the pupil region 2 It is mobile；Pin hole 5 is opened on the patch 1 other than the pupil region 2.

The fixation device of the utility model is bonded with patient's eyeball when in use, by patch 1, meanwhile, eyelid support portion 3 It is abutted respectively with the eyelid of corresponding position, each eyelid is opened, is fixed, simultaneously as being equipped with muscle between two eyelid support portions 3 Item 4 can be fixed between two eyelid support portions 3 it is possible thereby to be separated by rib 4 between two eyelid support portions 3 Distance, prevent two eyelid support portions 3 from moving inward under the action of eyelid, so prevent eyelid support portion 3 drive patch 1 move It is dynamic；Moreover, patch 1 can be bonded with eyeball surface, especially there is pupil region 2 at middle part, can make patch 1 and eyeball it Between it is relatively fixed, eyelid support portion 3 receive eyelid abutting force effect under, patch 1, eyelid support portion 3 are the same as phase between eyelid To fixation, under the limitation of patch 1, eyeball can be made relatively fixed with eyelid, so as to effectively fix eyeball, this When, doctor can be from injection from reserved pin hole 5.

The fixation device of the utility model can open eyelid and fixed eyeball simultaneously, kill two birds with one stone, and grasp without medical staff Make, reduce the operation difficulty of doctor, can also reduce or without support staff, is conducive to doctor and carries out injection operation,

Also, due to being provided with pin hole 5, it can quickly find injection point accurately in injection in order to doctor, improve injection efficiency And accuracy.

In some preferred embodiments, eyelid crosses eyelid support portion in order to prevent, can also as shown in figure 3, pass through by The upper end of fixed block turns down one bending part 10 of formation outward and pushes down eyelid when in use by bending part 10 and fix.

It should be noted that in the present embodiment, a pin hole 5, pin hole and cornea are only opened up at side position of keeping right Distance is preferably 3.5-4mm between region, this is not restriction of the utility model to pin hole 5 quantity and position, should manage Solution can also open up multiple pin holes 5 in some alternate embodiments, and according to actual injection demand, injection position, The reasonable position for determining pin hole 5.

Moreover, in the present embodiment, patch is set as the shape substantially consistent with each other with human eyeball, replaced some In the embodiment changed, patch can also be arranged to circle.

In the present embodiment, further specifically, the eyelid support portion 3 includes that several are spaced solid Determine block 3a, is equipped with metal support bar 3b in the fixed block 3a.It is possible thereby to each fixed block 3a be arranged by interval, so that this reality It can be suitable for differently contoured eyelid with novel eyelid support portion 3, meanwhile, pass through the metal support bar in each fixed block 3a 3b, can increase the support strength of fixed block 3a, can also can fixed block 3a by adjusting the Adjusting Shape of metal support bar 3b Profile, to adapt to the actual profile of eyelid.

In the present embodiment, it sets altogether and may also set up one or two in some embodiments there are three fixed block 3a Or extra three supporting blocks.

Further optimization place is that the fixed block 3a offers slot 6 away from the side of the patch 1, described Metal support bar 3b is set in the slot 6.It is possible thereby to realize that the separation between metal support bar 3b and fixed block 3a is deposited It puts, in actual use, is conveniently adjusted the shape of metal support bar 3b.It certainly, can also be by metal support bar 3b and fixed block 3a Between be integrally formed setting.

Further optimization place is, the rib 4 include ring be located at 2 outer rim of pupil region ring portion 4a, with Each fixed block 3a connected muscle portion 4b.So that the inner end of each muscle portion 4b is abutted with ring portion 4a, prevent rib 4 diagonal The interference in the region other than diaphragm area 2.

Certainly, rib 4 can be configured as other patterns, such as individual strip, and the both ends of each rib 4 are solid with one respectively Determine block 3a to be connected, alternatively, the end of a rib 4 is connected with two fixed block 3a simultaneously.

In order to improve the intensity of ring portion 4a, in some embodiments, a metal core 4c is equipped in the ring portion 4a.

Correspondingly, being equipped with metal core 4c in the muscle portion 4b.

It is noted that in order to according to the practical eye profile of patient, shape, the length of flexibly adjustment metal core 4c Degree, in the present embodiment, the rib 4 at the position the metal core 4c are equipped with mounting groove 7, are all provided on muscle portion 4b and ring portion 4a There is mounting groove 7.

Certainly, in some embodiments, mounting groove 7 can also be only set on muscle portion 4b.

In order to reduce the sense of discomfort at patient's eyeball, further optimization place is, the institute at the pupil region 2 1 aperture of patch setting is stated, described device further includes the cover plate 8 of the covering ring portion 4a.Pass through the patch at pupil region 2 1 aperture setting, can when being put into the present apparatus, prevent patch 1 directly be bonded at cornea, reduction the present apparatus to patient visual Bring sense of discomfort in upper, tactile can block patient by cover plate 8 in injection by the way that cover plate 8 is arranged on ring portion 4a Sight prevents injection needle from impacting to patients ' psychological, and then prevents the eyeball therefore generated from shaking.

It, can also be so set, specific as shown in figure 3, in the pupil region 2 in some embodiments that can be replaced Two sides be respectively provided with a rib 4, the both ends of the rib 4 are connected with the eyelid support portion 3 of corresponding position respectively.Thus may be used Be supported by two ribs 4 by two eyelid support portions 3 of setting, simplify structure.

It is noted that in order to improve the comfort level of patient's eyeball, while making patch 1 that there is certain intensity, institute Stating patch 1 includes the internal layer 1a being bonded with eyeball, and the outer layer 1b being arranged on the outside of the internal layer 1a, the hardness of the internal layer 1a Less than the hardness of the outer layer 1b.It is specifically that 1 internal layer 1a of patch is the silica gel that intensity is 40, outside is the silicon that intensity is 60 Glue.

In order to further increase the reliability of the utility model, in some preferred embodiments, as shown in figure 4, also Connection structure can be set on patch or rib, be connected by connection structure with extraneous handle 9, when fixed to eyeball, led to The control of the auxiliary of handle 9, fixed eyeball are crossed, ocular movemeut is further prevented.

Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model It protects in range.

Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
