In this embodiment, the surface of the hook 2 is a continuous smooth curved surface.
Specifically, since the hook portion 2 directly contacts the iris 9, the hook portion 2 has a sharp portion, which is extremely likely to cause damage to the eye, and thus the hook portion 2 needs to have a continuous and smooth curved surface.
In this embodiment, the sum of the lengths of the spike 1 and the inclined portion 3 is 2 to 6mm.
Specifically, when the sum of the lengths of the spike 1 and the inclined portion 3 is greater than 2mm, the spike 1 can pass out of the cornea 8 from the anterior chamber 11 of the eye, but when the lengths of the spike 1 and the inclined portion 3 are greater than 6mm, it may cause difficulty in manipulation in the anterior chamber 11 of the eye.
Preferably, the sum of the lengths of the spike 1 and the inclined part 3 is 3.5-4.5 mm.
Specifically, in this length range, particularly at 4mm, the pupil expansion effect is optimal, since the cornea 8 can be effectively penetrated out without affecting the operation of placing the pupil expansion hook needle in the anterior chamber 11 of the eye, and the spike 1 is held by the tool.
Example 3
Referring to fig. 4, in order to provide an embodiment 3 of a pupil-expanding hook needle according to the present application, the difference between the present embodiment and the embodiment 1 is that the pupil-expanding hook needle further includes a first flat needle portion 5 and a second flat needle portion 6, where the first flat needle portion 5 and the second flat needle portion 6 are respectively connected with two ends of the hook portion 2; the first needle flat part 5 and the second needle flat part 6 are parallel; the spike 1 is connected with the first flat needle 5, and a second included angle 7 is formed between the spike 1 and the first flat needle 5.
Specifically, the length of the first flattened portion 5 is greater than the length of the second flattened portion 6. After the hook part 2 hooks the iris 9, in order not to damage the cornea 8 of the eye when the pupil expanding hook needle is pulled, the spike part 1 needs to obliquely puncture the cornea 8 of the eye, so that the spike part 1 is pulled directly along the direction that the spike part 1 penetrates out of the cornea 8 of the eye, the hook part 2 can pull the iris 9 apart, and the perforation of the cornea 8 of the eye cannot be enlarged; through having second contained angle 7 between spike portion 1 and the first needle flat portion 5 for have certain contained angle between spike portion 1 and the crotch portion 2, when crotch portion 2 catches on iris 9, can directly make spike portion 1 impale the cornea 8 of eye, because spike portion 1 has had the contained angle with crotch portion 2, consequently need not to look for the suitable angle that spike portion 1 worn out the cornea 8 of eye again, directly pull spike portion 1 at this moment can make crotch portion 2 pull apart iris 9, through setting up second needle flat portion 6, can prevent crotch portion 2 from catching iris 9 after pulling iris 9, crotch portion 2 is deviate from iris 9, and first needle flat portion 5 and second needle flat portion 6 parallel arrangement, when operating crotch portion 2 catches on iris 9, when first needle flat portion 5 and iris 9 parallel, can confirm that second needle flat portion 6 has stablized iris 9 inboard, ensure crotch portion 2 can stably pull iris 9.
In this embodiment, the second included angle 7 between the spike 1 and the first flat portion 5 is 110 ° to 150 °.
Preferably, the first included angle 4 is 120 ° to 130 °, in which range the spike 1 does not obstruct the pupil 12, and the operator can pull the iris 9 apart with a small force to dilate the pupil. In particular, the first angle 4 is 125 ° and works optimally.
In this embodiment, the length of the first flattened portion 5 is 0.5 to 1.5mm.
Specifically, if the length of the first flattened portion 5 is too long, a large force needs to be applied when pulling the spike portion 1 to achieve a good pupil expansion effect. If the length of the first flattened portion 5 is too short, a high requirement is placed on the force applied by the operator, and if the force applied by the operator is slightly large, the iris 9 is easily pulled excessively, and the eyes are damaged. Therefore, the length of 0.5 to 1.5mm is preferably in the range of the first needle flat portion 5.
Preferably, the length of the first flat needle portion 5 is 0.8-1.2 mm, especially when the length of the first flat needle portion 5 is 1mm, the expected pupil expansion effect can be achieved without applying excessive force, the requirement on force-applying operators is not high, meanwhile, the pupil expansion speed can be ensured not to be too fast, and the possibility of damaging the iris 9 of the patient in the operation process is reduced.
