external diameter and front eyeball fixed bin 28 through hole closely cooperates, the sealing ring 15 that can be shifted be adjacent to slippage chamber 16 move cause can be shifted sealing ring 15 stretch expand negative pressure lock chamber 27 inner volume produce negative pressure, the animal eye cornea cut is covered on Corneal Contact grid 26 naturally and is tightly adsorbed, intact along with activity suction bracket 14 take out, can be shifted after movable suction bracket 14 is drawn out of that sealing ring 15 recovers shape and negative pressure disappears, just conveniently can obtain the perfect animal eye cornea of neat in edge so that carry out next step cornea scientific research and application afterwards again from Corneal Contact grid 26, repeatedly can repeat batch and cut this operation.
embodiment:
During use, first the large batch of fresh in vitro animal eyeball of experiment is got out, and the electronic quick animal eye corneal ablation device of corresponding size dimension is selected according to applied type of animal, and carry out disinfection in advance and the work in combination that breaks, first upwards tray motor 13 is started, first activity suction bracket 14 is advanced in slippage chamber 16 circular hole bottom front eyeball fixed bin 28, the sealing ring 15 that can be shifted is allowed to be adjacent to slippage chamber 16 good seal, upwards start lifting motor 11 and rear eyeball fixed bin 9 is left front eye fixed bin 28 top, the in vitro animal eyeball selected is put into the circular groove of front eyeball fixed bin 28 downwards, cornea is allowed just in time to be adjacent on Corneal Contact grid 26, and ensure on the cornea line of cut circle of dead knife cylinder positive alignment cornea on Corneal Contact grid 26 and sclera intersection, start lifting motor 11 downwards and rear eyeball fixed bin 9 clamping sleeve is contained in front eye fixed bin 28 top, at this time animal eyeball is substantially firmly fixed and can not rotates or slippage activity in box body, rotating sclerectome 6 has thrust in the sclera of animal eyeball back, starting sclerectome motor 19 drives drivewheel belt 20 to drive rotation sclerectome 6 to rotate according to the blade cut-out direction of sclera point of a knife 24, take advantage of a situation a circle by scleral incision, stop starting sclerectome motor 19, restarting cutter cylinder motor 1 is with moving knife cylinder driving wheel 3 to move downward, corneal ablation cutter 4 is driven and inserts in slippage chamber 16 circular hole on rear eyeball fixed bin 9 top simultaneously, shift sclera upper circular sclera line of cut 21 opening rotating sclerectome 6 incision downwards onto to stretch into, because in the middle of two boxes through one with the circle hole shape slippage chamber 16 of the animal eye cornea equal diameter that will cut, so corneal ablation cutter 4 can along the direction in circular hole slippage chamber 16, penetrating the scleral incision be cut open downwards enters eyeball inside slowly smoothly, eyeball inside is all that the vitreous body diameter in liquid and animal eyeball is less than corneal ablation cutter 4 internal diameter substantially, corneal ablation cutter 4 can not be affected move, when arrival is adjacent to the animal eye cornea place on Corneal Contact grid 26 to corneal ablation cutter 4 smoothly downwards, cutter cylinder motor 1 automatically strengthens strength and moves down corneal ablation cutter 4, there is a circle dead knife cylinder mutually can form shear action with corneal ablation cutter 4 outside Corneal Contact grid 26, sliding fast by animal eye cornea cutting down and just in time falling on Corneal Contact grid 26 along cornea line of cut clarity, now stop starting sclerectome motor 19, then tray motor 13 is started, drive activity suction bracket 14 moves downward, certain resistance is caused because the internal diameter in slippage chamber 16 in can be shifted sealing ring 15 external diameter and front eyeball fixed bin 28 through hole closely cooperates, the sealing ring 15 that makes to be shifted extends, expand the internal volume of negative pressure lock chamber 27 and then cause internal negative pressure to strengthen, naturally the cornea covered on Corneal Contact grid 26 is tightly adsorbed, slippage chamber 16 in the through hole being pulled out front eyeball fixed bin 28 by tray motor 13 along with activity suction bracket 14, the cornea installed in activity suction bracket 14 top is exposed at the moment, now because the sealing ring 15 that can be shifted recovers nature shape, the sealing ring 15 that can be shifted gets off to make the internal volume of negative pressure lock chamber 27 to become original state again owing to not having External Force Acting just naturally to relax, inner without negative pressure, animal eye cornea has just no longer tightly been attached on Corneal Contact grid 26, can be easy to conveniently be taken off gently by from naturally covering on Corneal Contact grid 26, repeat aforesaid operations can continuously carry out animal eye corneal ablation in enormous quantities thus obtain neat in edge perfection, quality is good, profile is uniform and smooth, the animal eye cornea that standard is consistent is so that carry out next step cornea scientific research and application afterwards again.
