The specific embodiment
The transportation container of this example is made up of the pedestal 10 with lens platform 15, cover 40 and lens maintaining part 50 with a pair of lens handle part 54.A pair of lens handle part 54 relatively is configured on the pedestal 10 between the portion that sows discord 60 that sows discord with the interval that can control IOL1.
In addition, keep stablize holding section 46 outstanding being provided with of interior side from covering 40 inner face, the front end of holding section 46 is stablized in above-mentioned maintenance, becomes R shape or coniform by chamfer machining, with delimitation introduction part 46a.
On the lens platform 15, and after 54 of lens handle parts have disposed IOL1, when cover 40 is stuck close on the pedestal 10, because the bight, side and the side 51 of introduction part 46a contact lens maintaining part 50, and dwindle into the interval that to control IOL1 slightly sowing discord portion 60, so IOL1 can not oppressed, and can not come off in fact and keeping from lens platform 15 and/or lens handle part 54.
In addition, pedestal 10 has guide hole 31, and cover 40 has cover pedestal holding section 44.Pedestal 10 possesses for being highlighted the projection 44N that is arranged to claw-like with front end in cover pedestal holding section 44 and engages the guide hole 31 that wears.By projection 44N is embedded in the guide hole 31, cover 40 pedestal 10 relatively engages slidably.Here, if the bight chamfer machining of cover pedestal holding section 44 is become the R shape, the resistance in the time of then can reducing to cover pedestal holding section 44 and insert has and can prevent the advantage of being out of shape.In addition, as other example, also can be, either party possesses guide hole 31 and cover pedestal holding section 44 and is highlighted the projection of being arranged to claw-like, and the opposing party possesses the hole for fastening and wear with above-mentioned projection, thereby both sides are engaging slidably.
In addition, when guide rail introduction part 32, the initial front face side that engages with projection 44N is roomy, and the words (with reference to Fig. 3) of the coniform 32a that side narrows down inside being configured as, so because the resistance can reduce that cover 40 inserted guide holes 31 time, can prevent pedestal 10 distortion so have, and the cover 40 that the is mounted advantage that is difficult for falling down.
Here, guide hole 31, though the place corresponding with cover pedestal holding section 44 represented two in the drawings, guide hole 31 promptly can be 2, also can be more than 3, and is identical with corresponding cover pedestal holding section 44 quantity, also can.
In addition, on cover 40, be provided with cam contact site 45, on lens maintaining part 50, be provided with cam surface 52. Cam contact site 45,40 inner face is outstanding to be arranged on interior side from covering.Cam surface 52 is arranged on the part of side 51 of lens maintaining part 50, by engaging slidably with cam contact site 45, the power that applies as the relative motion of covering 40 relative pedestals 10, act on the direction of dwindling at the interval that makes the portion of sowing discord 60, to be transformed on the said lens platform 15 and the power that bends of the optic 2 of the IOL1 of 54 configurations of lens handle part.In addition, cam surface 52 when cover 40 almost rotates with constant angular velocity, in order to control the bending speed of IOL1 to a certain extent, has been made level and smooth shape to it.
In addition, the intersection of narrow 33 on above-mentioned guide rail introduction part 32 and guide rail outstanding being provided with to slide prevent projection 36.Like this, slide and prevent projection 36 and projection 44N to interfere, can prevent the slip of cover 40 relative pedestals 10.
Use in the container in the transportation of this example, in turning left (counterclockwise), cover 40 makes the words of its counter-rotating (clockwise direction), the expansion that so relative lens handle part 54 is sowed discord portion 60, the optic 2 of the IOL1 that is bent does not catch up with recovery, in order to prevent that IOL1 from coming off from lens handle part 54, maintaining part fixed part 16 on pedestal 10 upper tongues is set as monolateral support overarm shape, and the free end side of above-mentioned maintaining part fixed part 16 forms the otch 16a more than 1 at least.Have again, only deposit gap SP between the free end of above-mentioned maintaining part fixed part 16 and the bottom surface, resettlement section 21.On the other hand, the bottom of the side 51 of lens maintaining part 50 is provided with maintaining part fixed projection 52P.That is to say, cover 40 is inserted in the pedestal 10, keep stablizing holding section 46 reducing glass maintaining parts 50, the otch 16a of maintaining part fixed part 16 (the 1st section otch) goes up and embeds maintaining part fixed projection 52P.Like this, lens handle part 54 is fixed on the pedestal 10 with the interval that can control IOL1.Cover 40 is turned left, cam contact site 45 compression lens maintaining parts 50, maintaining part fixed projection 52P moves by the free end of maintaining part fixed part 16, and among the gap SP between embedding and the bottom surface, resettlement section 21 (the 2nd section otch).At this moment, even reverse, maintaining part fixed projection 52P can not fall down from gap SP yet, so the state that lens handle part 54 can be kept reduced.Like this, can prevent that IOL1 from resetting into original shape.
In addition, pedestal 10 has the maintaining part resettlement section 20 of accommodating lens maintaining part 50, possesses the maintaining part holding section 23 that fastens with lens maintaining part 50 on the bottom surface, resettlement section 21 of maintaining part resettlement section 20, the projection of the claw-like of the pedestal holding section 59 of sagging and outstanding setting fastens with maintaining part holding section 23 below lens maintaining part 50.Maintaining part holding section 23, the front face side of the protrusion engagement of initial and pedestal holding section 59 is roomy, and be configured as the cone shape words that the inside side narrows down, so because the resistance can reduce lens maintaining part 50 insertion maintaining part holding sections 23 time, can prevent 10 distortion of lens maintaining part 50 and pedestal so have, and the lens maintaining part 50 that the is mounted advantage that is difficult for falling down.
In addition, as other examples, also can be, either party be the projection of the outstanding claw-like that is provided with for above-mentioned maintaining part holding section 23 and pedestal holding section 59, and the opposing party accepts above-mentioned projection and the shape that engages.Like this, for lens maintaining part 50 relative pedestals 10 can not drop in fact, pedestal holding section 59 is stuck close on the maintaining part holding section 23 slidably.
Also has the outstanding stable pin 24 of maintenance that is provided with maintaining part holding section 23, lens maintaining part 50 location and stable usefulness on bottom surface, above-mentioned resettlement section 21.Here, the stable pin 24 of maintaining part from bottom surface, resettlement section 21, up, is stablized outstanding setting the on 46 hands-off positions, holding section and the height at cover 40 cam contact sites 45 and maintaining part.For this reason, the stable pin 24 of maintaining part, the guide rail effect that the position is offset when having played the positioning action when lens maintaining part 50 is contained in pedestal 10 maintaining part resettlement sections 20 and having prevented 2 bendings of IOL1 optic, thereby the position that can stablize lens maintaining part 50.Here, in order to stablize the position of lens maintaining part 50, keep stable pin 24 preferably to have about 2～4, they preferably are located on the position that does not hinder the tweezers insertion.
Have, lens platform 15 is owing to reaching the openings 15P of lower aperture, so can import and discharge ethylene oxide gas and inject the visco-elastic material that the IOL1 implant surgery is used above having again.And then 1 ditch 15G can be set at least on the top of lens platform 15.Like this, ditch 15G is set on lens platform 15, does not bend IOL1 and can be easy to insert tweezers when it is taken out.Here, because IOL1 is the width that can be easy to and stably be configured, so the diameter of lens platform, the external diameter that cans be compared to IOL1 optic 2 most is big fully, and the diameter of openings, and the external diameter that cans be compared to IOL1 optic 2 most is fully little.
And then, near guide rail introduction part 32, with guide rail introduction part 32 concentric shapes worn circular-arc perforate 35.Like this, perforate 35 is set, cover 40 when being installed on the pedestal 10, near the guide rail introduction part 32 of pedestal 10 strains is being taken place, thus the resistance can reduce that cover 40 inserted guide rail introduction parts 32 time, so can prevent the distortion of pedestal 10.In order to improve the effect of spring, the length of perforate 35 is preferably 1～3 times of guide rail introduction part 32 length, be 1.5～3 times then better.
In addition, a pair of lens handle part 54 is linking integratedly between the elastomeric spring frame 53 with elastomeric spring structure.Here, above-mentioned elastomeric spring frame 53 has the elastomeric spring structure, is sowed discord on the direction of portion 60 in expansion so lens maintaining part 50 can energize.Like this, cover 40 is stuck close on the pedestal 10, and the bight, side of introduction part 46a contact lens maintaining part 50 and side 51 when dwindling the interval of the portion of sowing discord 60 slightly, then can maintain on the interval that can control IOL1 sowing discord portion 60.
And then, on the side, resettlement section 22 of maintaining part resettlement section 20, be provided with a pair of elastomeric spring frame stacker portion 25, the part of the elastomeric spring frame 53 by supporting lens maintaining part 50 slidably, the substance of lens maintaining part 50 moves in the time of can stoping the IOL1 bending.For this example, on the side, resettlement section 22 of above-mentioned maintaining part resettlement section 20, a pair of elastomeric spring frame stacker portion 25, be arranged on the direction that the overbending direction of relative IOL1 optic 2 keeps straight on, the part of the elastomeric spring frame 53 of lens maintaining part 50, by intercalation in elastomeric spring frame stacker portion 25, thereby can support the part of elastomeric spring frame 53 slidably, so can stop the rotation of lens maintaining part 50.Factors such as thickness when considering these elastomeric spring frame stacker portion 25 employed resins and molding, the thickness that it has preferably can prevent warpage.
In addition, lens maintaining part 50, possessing the 1st engaged claw 57 near the front end to the outstanding support sector's supporting pillar 55 of the interior direction of the sowing discord portion 60 lens handle part 54, near the front end that clips support sector's supporting pillar 55 of portion of sowing discord 60 and the 1st engaged claw relative localization relative lens handle part 54 possesses the 2nd engaged claw 58.Like this, it is reduced to sow discord portion 60, and the 1st engaged claw 57 and the 2nd engaged claw 58 fasten, so can keep the state that IOL1 is bent.Here, for the 1st engaged claw 57 carries out strain easily with the 2nd engaged claw 58 support sector's supporting pillar 55 when contacting and engage, on the part of support sector's supporting pillar 55, be provided with recess 57R.Here, recess 57R also can be located at any side in the left and right sides of support sector's supporting pillar 55.
For this example, support sector's reinforcement 56 be located at support sector's supporting pillar 55 above.Support sector's reinforcement 56 is located at the words of the base end side of support sector's supporting pillar 55, the interference of the above-below direction when the 1st engaged claw 57 and 58 engagings of the 2nd engaged claw will improve, except cover 40 rotation become level and smooth, when it being taken out, also can be easy to insert tweezers not bending IOL1.In addition, this example, support sector's reinforcement 56 are provided with two, accommodate the support sector 3 of IOL1 between 2 support sector's reinforcements 56, so can prevent the rotation of IOL1.Like this, IOL1 can positively bend on desirable position.In addition, as other examples, by on the 1st engaged claw 57 support sector's reinforcement 56 being set, the support sector 3 of IOL1 can be by 56 tyings of support sector's reinforcement.
The inboard shape of the lens handle part 54 in this example has been made into towards the cone shape of sowing discord portion's 60 directions expansion, and the R shape is processed in its end chamfering.For this reason, bending IOL1 when taking out IOL1 with tweezers, can not damage the optic 2 of IOL1.
For the portion that sows discord 60 of lens handle part 54 and since its lens handle part 54 front ends between the interval make identical slightly with the external diameter of IOL1 optic, perhaps than its smaller opening; Interval between the side 54b of the opposing party's lens handle part 54, make identical slightly with the external diameter of IOL1 optic 2, perhaps than its bigger interval, so it has been made into the formation that IOL1 can be easy to be configured in 54 of lens handle parts.
In addition, in other examples, can form the ditch shape to lens handle part 54.At this moment, lens platform 15 is set, also can controls IOL1 even on pedestal 10, do not give prominence to.
The section of lens handle part 54, above forming 54c still below 54d all gentle dip become cone shape ditch shape, so even during the IOL1 bending, IOL1 can not eject from the lens handle part yet.That is to say that IOL1 optic 2 can bend definitely.The inclination angle γ of following 54d generally preferably is about 0～7 degree, be then better about 5 degree, when using biconvex lens, near the curved surface tangent slope approximately equal of the IOL1 optic 2 the position that joins with the following 54d of IOL1 optic 2 and lens maintaining part 54 is best.On the other hand, above the inclination angle δ of 54c be preferably 5～35 degree, be then better about 15～25 degree.
In addition, overlook cover 40, its profile approximate circle shape, but such profile is not limited to toroidal, also can do the shape that quadrangularly, hexagon and octagon etc. make cover 40 rotations easily, is not particularly limited.In addition, cover 40 is not defined as the motion of relative pedestal 10 rotational slides.That is to say that the slip of cover 40 relative pedestals 10 of the present invention not necessarily just rotatablely moves, also can be the motion that rectilinear motion etc. constitutes other motions.
