Abstract

The utility model provides a nucleus crushing plier with a crystalline lens. The structure of the nucleus crushing plier consists of an upper plier handle, a lower plier handle, an upper plier tip and a lower plier mouth, the right ends of the upper plies handle and the lower plier handle are connected with each other by a hinge, the left ends of the upper plier handle and the lower plier handle are inserted together through a primary-secondary interface, and the upper plier tip and the lower plier mouth are respectively arranged on the rightmost ends of the upper plier handle and the lower plier handle. Compared with the prior art, the nucleus crushing plier with the crystalline lens has the characteristics of rational design, simple structure, safety and reliability, convenient use, good operation stability, high success ratio of operation and the like, thereby having good promotion and use value.

Description

Crystalline lens fragmentation nucleus pincers

1, technical field

This utility model relates to a kind of medical apparatus and instruments, the cataractous crystalline lens fragmentation nucleus pincers of specifically a kind of treatment.

2, background technology

Cataract is main in the world diseases causing blindness, 2,000 ten thousand people is probably arranged now in the world owing to the cataract blinding, and other has 100,000,000 needs of patients surgery recovery visions, and in most of Africa and Asian countries, the cataract patient accounts for half of blind person at least.Along with the growth and the aging of world population, cataractous sickness rate will be more and more higher.Worldwide treat cataractous measure at present and still be the means of mainly recovering lost eyesight with operation or implantable artificial crystal.The main mode of operation is that ultrasonic emulsification associating artificial intraocular lenses implants, but because the costliness of surgical apparatus and surgery cost has limited its use at basic hospital.Traditional ECCE operation, otch is near limbus of corneae, though be beneficial to giving birth to of crystal nuclear in the art, but because otch is big, need to sew up the 5-7 pin, the pulling force of otch suture can cause the cornea of vertical incision direction warp precipitous, produces the expendable astigmatism that cornea exists in the tangible postoperative long period, and the tightness of each suture and pin spacing also are to cause big and the factor of irregular astigmatism, thereby have a strong impact on Postoperative visual acuity.Therefore for basic hospital, carry out small incision cataract surgery, proper.If do not carry out the ophthalmic fragmentation nucleus, the length of little otch at least should be at 7-8mm, if fragmentation nucleus within the eye then makes the length of otch shorten half at least, thereby reduced the postoperative patient astigmatism on the great achievement degree very much.Present cataract operation fragmentation nucleus, mostly be bimanualness, two handss are operated respectively and are cut nuclear cutter and two operating theater instruments of backing plate, owing to be bimanualness, be unfavorable for the stable of anterior chamber, corneal endothelium and posterior lens capsule film cause damage and cause corneal endothelium to lose compensatory and vitreous body such as deviates from complication easily simultaneously.Good solution is not also arranged at present.

3, summary of the invention

The novel purpose of this use is to overcome existing deficiency in the prior art, and a kind of crystalline lens fragmentation nucleus pincers for the treatment of the one-hand operation of cataract ophthalmic are provided.

The purpose of this utility model realizes in the following manner, this crystalline lens fragmentation nucleus pincers by upper plier handle, lower plier handle, go up the pincers point and down pincers chew and form, the right-hand member of upper plier handle and lower plier handle is connected through the hinge, the left end of upper plier handle and lower plier handle is plugged on together by the primary and secondary interface, last pincers point is chewed the low order end that is separately positioned on upper and lower pincers handle with clamping down, and last pincers point and following pincers are chewed merging and are

Word.

The capable advantage of this heart on probation is that simple in structure, easy to operate, the strong and accuracy height of one-handed performance stability can improve operation quality and success rate greatly.

5, the specific embodiment

With reference to Figure of description crystalline lens fragmentation nucleus pincers of the present utility model are done following detailed explanation.

Crystalline lens fragmentation nucleus pincers of the present utility model, its structure by upper plier handle 2, lower plier handle 3, go up pincers point 5 and down pincers chew 6 and form, the right-hand member of upper plier handle 2 and lower plier handle 3 is connected by hinge 4, the left end of upper plier handle 2 and lower plier handle 3 is plugged on together by primary and secondary interface 1, last pincers point 5 and down pincers chew 6 low order ends that are separately positioned on upper and

lower pincers handle

2,3.

Last pincers point 5 and following pincers are chewed 6 merging and are

Word, following pincers are chewed 6 and are annular or oval ring.

It is circular or oval-shaped thin slice that following pincers chew 6.

Following pincers are chewed 6 integral body and are reclinate curved surface.

Embodiment

Cataract operation carries out otch 3-4mm routinely, will go up pincers points and down pincers chew to inject in the otch and clamp nucleus, merge gently go up the pincers point and down pincers chew and nucleus pressed from both sides broken, will press from both sides the taking-up one by one from otch of broken nucleus at last.

Claims

1, crystalline lens fragmentation nucleus pincers, it is characterized in that by upper plier handle, lower plier handle, go up the pincers point and down pincers chew and form, the right-hand member of upper plier handle and lower plier handle is connected through the hinge, the left end of upper plier handle and lower plier handle is plugged on together by the primary and secondary interface, and last pincers point and following pincers are chewed the low order end that is separately positioned on upper and lower pincers handle.

2, crystalline lens fragmentation nucleus pincers according to claim 1 is characterized in that, last pincers point and following pincers are chewed to merge and are
