Abstract
The invention belongs to an irido-pupillary sphincter clamping ring used in an ophthalmic surgery and an application method thereof. The problems to be solved in the background art are that a plurality of points are penetrated through the cornea, damage is large, and aphakic eyes and pseudophakic eyes can be subjected to the ophthalmic surgery only. The used technical scheme comprises: an elastic clamping ring is not enclosed and is provided with an opening, at least one end of the opening is provided with a fixation hook, a plurality of clamping jaws with tops having bayonets are arranged in the ring of the elastic clamping ring, and a space included angle inclined towards the ring is formed by the plane in which the clamping jaws are and the plane in which the elastic clamping ring is. When the clamping ring is used, the fixation hook is used for hooking the clamping jaws at corresponding positions to determine a diameter adapted to the size of the pupil of an eyeball, the fixation hook is caused to approach the iris tissues of the eyeball so that a plurality of clamping jaws are in contact with the iris tissues, and a plurality of parts of the iris tissues are put into the bayonets at the tops of the clamping jaws at corresponding positions so as to achieve the purpose of decreasing the pupil. The irido-pupillary sphincter clamping ring can be applied to the therapy for paralytic mydriasis of sphincter pupillae, and has the advantages that the surgical wound is free and the operation is simple and convenient.
Description
Technical field: the invention belongs to apparatus and application process thereof that ophthalmologic operation uses, Irido-pupillary sphincter clamping ring and application process thereof 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: purpose of the present invention is exactly to propose a kind of Irido-pupillary sphincter clamping ring of ophthalmologic operation use and the technical scheme of application process thereof, 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.Its employed material is polymethyl methacrylate (PMMA), has suitable biocompatibility, elasticity, rigidity and smoothness.The plane, place of gripper jaw and the plane, place of resilient clamp ring form the space angle A that tilts in ring be 45 degree, and effective like this holding ring of having avoided contacts with the extensive of iris tissue, reduces the iris tissue damage.
A kind of method of using the Irido-pupillary sphincter clamping ring that uses as above-mentioned a kind of ophthalmologic operation, during application 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 pupil 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 the present invention 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 the present invention.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.Its employed material is polymethyl methacrylate (PMMA).The plane, place of gripper jaw 3 and the plane, place of resilient clamp ring 1 form the space angle that tilts in ring be 45 degree.
Use the method for the Irido-pupillary sphincter clamping ring that uses as above-mentioned a kind of ophthalmologic operation, during application according to the size of patient's eyeball, 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 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.
