Abstract
This utility model discloses a kind of microscopic intra-ocular magnetic foreign body extractor, it is by magnetic conductive pole, strong magnetic iron prop, sleeve and hold handle and form, magnetic conductive pole and its base adopt stronger martensite or the ferrite type stainless steel material of magnetic property to make, the magnetic force of strong magnetic iron prop can be conducted to well to the tip of magnetic conductive pole, solved the problem of double requirements of this microscopic intra-ocular magnetic foreign body extractor to magnetic conductive pole mechanical strength and magnetic conductive pole tip magnetism intensity, simple in structure, easy to use, medical worker is hand-held can directly extend into magnetic conductive pole the wounded's ophthalmic, approach after foreign body foreign body sucking-off, during due to foreign body, eyeball is not caused to any pressure, in the process of taking out foreign body, can there is not the situation that foreign body comes off, thereby can not cause further wound to retina, can reduce the generation of postoperative complication, shorten operating time, good through result of use.Range of application: 1, vitreous-body-retina magnetic foreign body takes out; 2, in crystalline lens, magnetic foreign body takes out.
Description
Technical field
This utility model relates to a kind of remover for foreign body in eye tool, specifically a kind of microscopic intra-ocular magnetic foreign body extractor.
Background technology
Intraocular foreign body is a kind of common severe ocular trauma.Enter the foreign body of ophthalmic, generally need the operation of vitreous excision associating Extraction of intraocular foreignbody, in operation, with foreign body forceps, the foreign body that enters ophthalmic is pressed from both sides out, during foreign matter clamping, a little accidentally will cause further wound to retina, even cause retinal hole and cause serious complication; During foreign body, also easily come off and again damage retina.According to clinical statistics analysis, the foreign body that enters ophthalmic more than 80% has magnetic, for this class foreign body, adopts the mode of magnetic-adsorption to take out in operation, more can overcome the many deficiencies that exist with foreign body forceps gripping, has carried out long research for this reason.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiency that above-mentioned prior art adopts foreign body forceps gripping intraocular foreign body to exist, and a kind of microscopic intra-ocular magnetic foreign body extractor that takes out intraocular foreign body in vitrectomy by the mode of magnetic-adsorption is provided.
The technical scheme in the invention for solving the technical problem is: a kind of microscopic intra-ocular magnetic foreign body extractor, it is by magnetic conductive pole, strong magnetic iron prop, sleeve and hold handle and form, described barrel forward end closes up, rear portion arranges female thread, and holds handle and all with metal material, manufacture; Described magnetic conductive pole is made with martensite or ferrite type stainless steel material, and rear portion arranges the base identical with strong magnets column section; Described magnetic conductive pole base and strong magnetic iron prop are contained in sleeve from front to back successively, by threaded engagement spinning, at the handle of holding of sleeve rear end, fix, and magnetic conductive pole is stretched out by the front port of sleeve.
This remover for foreign body in eye tool provided by the utility model, magnetic conductive pole and its base adopt stronger martensite or the ferrite type stainless steel material of magnetic property to make, the magnetic force of strong magnetic iron prop can be conducted to well to the tip of magnetic conductive pole, solved the problem of double requirements of this microscopic intra-ocular magnetic foreign body extractor to magnetic conductive pole mechanical strength and magnetic conductive pole tip magnetism intensity, simple in structure, easy to use, medical worker is hand-held can directly extend into magnetic conductive pole the wounded's ophthalmic, approach after foreign body foreign body sucking-off, during due to foreign body, eyeball is not caused to any pressure, in the process of taking out foreign body, can there is not the situation that foreign body comes off, thereby can not cause further wound to retina, can reduce the generation of postoperative complication, shorten operating time, good through result of use.
Range of application:
1, vitreous-body-retina magnetic foreign body takes out: during vitrectomy, find after magnetic foreign body it is fully free, hand-held microscopic intra-ocular magnetic foreign body extractor then, directly stretches into magnetic conductive pole the wounded's ophthalmic, approaches after foreign body its sucking-off;
2, in crystalline lens, magnetic foreign body takes out: when carrying out traumatic cataract surgery, the magnetic conductive pole of microscopic intra-ocular magnetic foreign body extractor is directly extend in crystalline lens foreign body sucking-off.
Accompanying drawing explanation
The structural representation of the microscopic intra-ocular magnetic foreign body extractor that Fig. 1 provides for this utility model embodiment;
Labelling in figure: 1, magnetic conductive pole, 2, strong magnetic iron prop, 3, sleeve, 4, hold handle, 5, the base at magnetic conductive pole rear portion.
The specific embodiment
For this utility model is described better, enumerate following instance, but protection domain of the present utility model is not limited only to this, its claimed scope is recorded in the claim of claim.
With reference to accompanying drawing, this microscopic intra-ocular magnetic foreign body extractor that this utility model embodiment provides, it is by magnetic conductive pole 1, rubidium ferrum boron strong magnetic iron prop 2, sleeve 3 and hold handle 4 and form, described sleeve 3 front ends close up, rear portion arranges female thread, and holds handle 4 and all use the manufacture of Austenitic stainless steel material; Described magnetic conductive pole 1 use martensite or ferrite type stainless steel material are made, and rear portion arranges the base identical with cylindrical rubidium ferrum boron strong magnetic iron prop 2 cross sections; Described magnetic conductive pole base 5 and rubidium ferrum boron strong magnetic iron prop 2 are contained in sleeve 3 from front to back successively, by threaded engagement spinning, at the handle 4 of holding of sleeve 3 rear ends, fix, and magnetic conductive pole 1 is stretched out by the front port of sleeve 3.
