Abstract

The utility model belongs to an iris pupilla constrictor retaining ring for ophthalmologic operation, which aims at solving the problems that in the background technology, as multiple-point punchthrough of a cornea has great damage, a non-crystal eye or a manual crystal eye can be conducted on only. The main points of the adopted technical scheme are as follows: the elastic retaining ring is in a shape of a non-closed opening; at least one end of the opening position is provided with a fixing hook; the elastic retaining ring is internally provided with a plurality of retaining jaws with the top ends being provided with clamping ports; and the plane where the retaining jaws are positioned forms a space included angle inclining towards the inside of the ring with the plane where the elastic retaining ring is positioned. When in use, the fixing hook is used for hooking the retaining jaws at corresponding positions so as to determine the diameter adaptive to the size of a eyeball pupilla, retaining ring is close to the iris tissue of the eyeball to lead the plurality of the retaining jaws to be contacted with the iris tissue, and then a plurality of parts of the iris tissue are placed into the clamping ports at the top ends of the corresponding positions of the clamping jaws, thus realizing the purpose of reducing the pupilla. The iris pupilla constrictor retaining ring can be applied to the treatment on the paralysis mydriasis of the pupilla constrictor, and has the advantages of no surgical wound, simple and convenient operation and the like.

Description

The Irido-pupillary sphincter clamping ring that a kind of ophthalmologic operation uses

Technical field: this utility model belongs to the apparatus that ophthalmologic operation uses, the Irido-pupillary sphincter clamping ring that particularly a kind of ophthalmologic operation uses.

Background technology: make the contracted pupil of eye disease patient in the existing ophthalmologic operation if desired, the general method of sewing up that adopts is sewed up iris tissue, and term is called " purse string suture ".The open defect one that this modus operandi exists is to need the break-through of corneal multiple spot, and tissue injury is big, sews up loaded down with trivial details; The 2nd, can only implement aphakia or artificial intraocular lenses's eye, and to there being the crystal eye to implement.

Summary of the invention: the purpose of this utility model is exactly the technical scheme that proposes a kind of Irido-pupillary sphincter clamping ring of ophthalmologic operation use, and exist with the solution background technology: need the break-through of corneal multiple spot, tissue injury is big, sews up loaded down with trivial details; And can only implement aphakia or artificial intraocular lenses's eye, and to there being the crystal eye to implement.Solving this technical problem the technical scheme that is adopted is: the Irido-pupillary sphincter clamping ring that a kind of ophthalmologic operation uses, it is characterized in that the resilient clamp ring is not closed opening shape, at least one end of opening part is provided with fixation hook, some tops band bayonet socket gripper jaw is set in the ring of resilient clamp ring, and the plane, place of gripper jaw and the plane, place of resilient clamp ring form the space angle of inclination in ring.Diameter when wherein, scale being set on the resilient clamp ring determining that the resilient clamp ring uses.

During use according to the size of patient's eyeball pupil, the gripper jaw that catches on the relevant position with fixation hook is determined and the adapt diameter of resilient clamp ring of eyeball size, make some gripper jaws contact iris tissues the iris tissue of the close eyeball of this Irido-pupillary sphincter clamping ring, again the several portions of iris tissue is inserted within the top bayonet socket of gripper jaw of relevant position, thereby realize miotic purpose.

The beneficial effect that this utility model is had compared with the prior art is: owing to adopt technique scheme, use the apparatus clamping just can realize miotic purpose, iris tissue does not have operation wound, easy to operation, to being arranged, also can implement the crystal eye, thoroughly exempt the loaded down with trivial details of background technology stitching, significantly improved operation efficient and quality.Be suitable for the sphincter pupillae that a variety of causes causes and benumb mydriatic treatment, be particularly suited for still not having the transparent platycoria of effective Therapeutic Method crystal at present, and wound, neural paralysis, glaucoma etc.

Description of drawings: Fig. 1 is the structural representation of the Irido-pupillary sphincter clamping ring of a kind of ophthalmologic operation use of this utility model.Fig. 2 is the structural representation that the plane, place of the plane, place of gripper jaw and resilient clamp ring forms the space angle of inclination in ring.

The specific embodiment: with reference to figure 1, Fig. 2, the Irido-pupillary sphincter clamping ring that a kind of ophthalmologic operation uses, it is characterized in that resilient clamp ring 1 is not closed opening shape, at least one end of opening part is provided with fixation hook 4, some tops band bayonet socket gripper jaw 3 is set in the ring of resilient clamp ring 1, and the plane, place of gripper jaw 3 and the plane, place of resilient clamp ring 1 form the space angle of inclination in ring.Diameter when scale 2 being set on the resilient clamp ring 1 determining that resilient clamp ring 1 uses.During use according to the size of patient's eyeball pupil, the gripper jaw 3 that catches on the relevant position with fixation hook 4 is determined and the adapt diameter of resilient clamp ring 1 of eyeball pupil size, make some gripper jaws 3 contact iris tissues the iris tissue of the close eyeball of this Irido-pupillary sphincter clamping ring, again the several portions of iris tissue is inserted within the top bayonet socket of gripper jaw 3 of relevant position, thereby realize miotic purpose.
