Abstract
The invention relates to strabismus corrector and application thereof. The corrector is a metal closed ring which is enclosed by four arc sections which comprise two long arc sections and two short arc sections, and the two long arc sections and the two short arc sections of the closed ring symmetrically form an cambered surface shape in pairs; the cambered surface of the closed ring is anastomotic with the radian of each eyeball, and thimbles are arranged on the long arc sections. Both ends and the middle position of each long arc section are respectively provided with a thimble or three thimbles are uniformly arranged on the long arc sections. The thimbles of the long arc sections are stitching grooves. The invention is applied to correct strabismus and correct residual strabismus after an operation to achieve complete normotopia, has simple structure and accurate adjustment, is easy for postoperation adjustment and carries out stepless fine adjustment on eye positions; a patient has less pain, and the residual strabismus can reach complete normotopia after diorthosis, thereby the invention can improve the curing rate of the strabismus and reducing amblyopia generation; the adjusting amplitude on a single side eye can reach 10 degrees at maximum; if the strabismus corrector is used by double-side eyes, the adjustable range reaches more than 20 degrees.
Description
Technical field
The present invention relates to a kind of ophthalmic medical device and application thereof, particularly a kind of strabismus corrector and application thereof.
Background technology
Stravismus is a kind of common vision disease, accounts for 3～4% of total population, and operative treatment is the most frequently used therapeutic scheme.But, the rectification degree of accuracy of traditional operation is very low, repeatedly after the operation, only there is 20% patient to reach basic normotopia and function and curing, all the other patients of 80% develop into permanent visual impairment in various degree, i.e. amblyopia and stereopsis forfeiture, and the effect of beauty treatment is only played in operation, What is more, and congenital esotropia has only 1% function and curing rate.Why very low the rectification degree of accuracy of traditional operation is, be because in traditional operation, the minimum that every shortening 1mm extraocular muscles can be proofreaied and correct stravismus is 3～5 degree, so 5 degree with interior stravismus or postoperative remnants stravismus skin ulcer clinically, basically abandon further operative treatment, because of precision is limit, operation caused strong most probably or owed strong once more.
Summary of the invention
The purpose of this invention is to provide a kind of strabismus corrector and application thereof, to remedy the above-mentioned deficiency of prior art.
The present invention mainly is the device that is used with traditional operation, and rectifiable postoperative residue stravismus reaches complete normotopia, thereby improves the function and curing rate of stravismus, reduces amblyopia and takes place.
Strabismus corrector of the present invention, it is characterized in that this appliance is the metallic closed ring that four arcs of two long arc sections and two short arc segments surround, and two long arc sections and two symmetrical in twos arc surfaceds that are of short arc segments of closed hoop, the cambered surface of this closed hoop and the radian of eyeball match, and above-mentioned long arc section is provided with thimble.Be applied to correct stravismus and postoperative and correct remaining stravismus to reach complete normotopia.
The thimble of above-mentioned long arc section also can be the suture groove, promptly substitutes thimble with the suture groove, to simplify processing technology.
Of the present invention simple in structure, with low cost, easy to operate, can outside conjunctiva, operate, postoperative adjustment easily, and adjust accurately, patient's misery is little, the remaining stravismus of postoperative straightening can reach complete normotopia, thereby improve the function and curing rate of stravismus, reduce amblyopia and take place, with the traditional suture adjusted relatively, the latter also need open conjunctival incision and directly operate on wound, and a lot of adults can't tolerate.

Wherein, 1, the long arc section, 2, short arc segments, 3, thimble, 4, the suture groove, 5, eyeball, 6, extraocular muscles, 7, the not-go-end of extraocular muscles, 8, pupil, A, closed hoop.
The specific embodiment
As shown in Figure 1 and Figure 2, technical scheme of the present invention is a metallic closed ring A of four arcs of two long arc sections 1 and two short arc segments 2, and two long arc sections 1 and two symmetrical in twos arc surfaceds that are of short arc segments 2 of closed hoop A; Fig. 3 represents that the cambered surface of this closed hoop A and the radian of eyeball 5 match; Above-mentioned long arc section 1 is provided with thimble 3.Can respectively be provided with a thimble 3 as two ends in long arc section 1; In addition, also can be provided with a thimble 3, promptly be provided with three thimbles 3 equably on this long arc section 1, thereby more help fine setting in the centre position of long arc section 1.Can certainly as required position and number thimble 3 be set.
Consider that to make process structure simple, the thimble 3 of above-mentioned long arc section 1 can be a suture groove 4, and as shown in Figure 2, promptly this suture groove 4 is equivalent to the groove structure on the long arc section 1, and the present invention that is more convenient for is integrative-structure.
In addition, above-mentioned closed hoop A and thimble 3 can be one also, so that the molding on the one-time process.
The length of above-mentioned long arc section 1 is 8-12mm, and diameter is between 0.5-1.0mm.
The length of above-mentioned short arc segments 2 is 6-10mm, and diameter is between 0.25-0.75mm.
In case of necessity, the diameter of above-mentioned long arc section 1 and short arc segments 2 can be identical, as about 0.6mm, thereby makes the present invention more brief on technology.The length of obvious above-mentioned long arc section 1 and short arc segments 2 is selected should be suitable with eyeball 5.
The present invention is made by histocompatibility fabulous gold and alloy material thereof, and promptly above-mentioned metallic closed ring A and thimble 3 are that gold and alloy material thereof are made.
The present invention is applied to the orthpia operation, adjusts the size of appliance closed hoop by postoperative and corrects remaining stravismus to reach the purpose of the complete normotopia of eyes.Promptly this strabismus corrector is applied to postoperative adjustment and postoperative and corrects remaining stravismus to reach complete normotopia.
As Fig. 4 and Fig. 5, the use of the present invention in the orthpia operation: when this strabismus corrector retreats extraocular muscles 6 in the orthpia operation, the present invention can be linked to each other with medial rectus by thimble 3 or suture groove 4 on its long arc section 1, the thimble 3 of opposite side or suture groove 4 are fixed on the original stop of medial rectus, thereby correct stravismus.The adult can carry out under local anaesthesia, can carry out under of short duration general anesthesia the child.After the operation, utilize the plasticity of closed hoop A of the present invention, the distance of adjusting between two long arc sections 1 of closed hoop A with medical fine setting pincers or vascular forceps reaches normotopia to adjust the squinting eye position.And adjust closed hoop A and can outside conjunctiva, carry out, need not to open conjunctival incision.
Experimental result shows that the present invention can do stepless meticulous adjusting to the eye position, can reach 10 degree to one-sided amplitude of accommodation maximum, if bilateral uses adjustable range to reach more than 20 degree.
