Abstract
The utility model relates to a magnetic foreign body extractor from eyes, which is composed of a body part and a probe part which are tightly connected. The body part comprises an aluminium-material casing in which an iron, boron and neodymium rare earth magnetic core is arranged. The probe part is made into a hockey stick shape or a cylindrical shape. The utility model can be extended into the eyes under a direct vision and magnetic foreign bodies maintained in the eyes can be directly absorbed. The trauma resulted from the process of taking out the magnetic foreign bodies can be decreased furthest, and tThereby, the happening of complication can be reduced. In addition, the utility model has the advantages of good directivity, small size, portability and easy operation.
Description
This utility model relates to a kind of magnetic intraocular foreign body extractor.
Intraocular foreign body is a kind of common but severe ocular injury, most of intraocular foreign bodys are magnetic foreign body, the magnetic foreign body that volume is bigger generally takes out by the outer electric magnet apparatus of eye, its shortcoming can not be used for microsurgery for this apparatus, the little magnetic foreign body of ophthalmic then can not got (the particularly little magnetic foreign body at close optic nerve place), and damage is big in the operation process.The little foreign body of ophthalmic magnetic is generally taken the photograph son by ophthalmic and is taken out, and its shortcoming is an inconvenient operation, easy damaged ophthalmic surrounding tissue in the operating process.
The purpose of this utility model is to provide a kind of ophthalmic size magnetic foreign body, directionality of conveniently taking out to, magnetic intraocular foreign body extractor that volume is little.
This utility model is achieved in that this product is made of body and probe portion, and body closely is connected with probe portion, and body comprises an aluminum shell, is provided with a ferrum, boron, neodymium rare earth magnetic core in the aluminum shell; Probe portion is the hockey clavate or is cylindric, it by the higher glass of permeability not alloy constituted.
Below in conjunction with drawings and Examples this utility model is described in detail.
Fig. 1 is the section of structure of hockey clavate for this utility model probe portion.
Fig. 2 is cylindric section of structure for this utility model probe portion.
Consult shown in Figure 1, this utility model is made of body and probe portion, body closely is connected with probe portion, and body comprises an aluminum shell (1), is provided with a ferrum, boron, neodymium rare earth magnetic core (2) in the aluminum shell (1), probe portion (3) is the hockey clavate, by glass not alloy constituted, end is duckbill, long 40mm, wide 2mm, magnetism intensity are that 25～35 millis are special.
Consult shown in Figure 2ly, this product structure is identical with Fig. 1, and just probe portion (4) be cylindric, and long 40mm, diameter are 1.5mm, and magnetism intensity is 20～50 spies in the least.
This utility model is applicable to anterior chamber's foreign body, muddy crystal foreign body, vitreous body and retina have the vitreous chamber floating foreign body of obvious damage, be positioned at a back segment retinal surface or the part be embedded in ball wall foreign body and look the nipple Superficial Foreign Body, can under direct-view, stretch into ophthalmic, directly will be trapped in the magnetic foreign body sucking-off of ophthalmic.This orientating products is good, and volume is little, and is light, easy to operate, sucking-off foreign body gently in the magnetic foreign body removal surgery within the eye causes further damage to eye inner tissue thereby avoid foreign body to break away on ball wall and the foreign body passage from back to front, thereby reduces the generation of complication.
