Description
Technical field
This utility model relates to a kind of ophthalmology operating theater instruments commonly used, particularly a kind of corneal foreign body hook.
Background technology
Corneal foreign body is one of modal ocular injury of ophthalmology outpatient service, and is wherein common with the ferrous metal foreign body, and according to the document newspaper, the highest more than 90% of outpatient service corneal foreign body patient that accounts for is mainly in the builder, decoration worker, metal processor etc.The processing of shallow-layer corneal foreign body mainly uses disposable syringe syringe needle or corneal foreign body to hook up out to give anterior corneal surface anesthesia back in outpatient service.
The method of extensive use is to use the 1ml syringe needle to carry out the foreign body taking-up clinically at present.The method has the following advantages: 1, draws materials conveniently, and with low cost.2, the disposable use of apparatus, strict aseptic, the risk of reduction cornea secondary infection.But also have following shortcoming simultaneously: 1, syringe needle is extremely sharp, and patient's eyeball causes corneal injury easily when rotating; 2, corneal foreign body usually is attached to anterior corneal surface after rejecting, and directly takes out difficulty with syringe needle, damages normal cornea easily; Often need this moment to dip in out with aseptic wet cotton swab in addition; If the patient blinks, foreign body may be transferred to other positions of conjunctival sac, even lose, cause and take out difficulty; 3, cornea rust ring strikes off inconvenience with syringe needle, causes the normal cornea epithelial damage easily.Traditional corneal foreign body hook can overcome above-mentioned 1 shortcoming, but still can not overcome above-mentioned 2,3 described shortcomings.
The corneal foreign body hook that for this reason has the author also to design to have magnetic, even some corneal foreign body hook also self has power supply, light source and magnifier.These designs have solved above-mentioned shortcoming to a certain extent, have made things convenient for ophthalmologist's operation.But the develop rapidly of ophthalmology has in recent years brought new challenge for again the application of this type of corneal foreign body hook, mainly show as: 1, along with the microscopical popularization and application of ophthalmology, ophthalmology operation and operation have entered the micro-epoch, and ophthalmology out-patient department of basic unit also generally is equipped with the ophthalmology slit lamp microscope.Itself promptly has good illumination and enlarging function ophthalmology slit lamp microscope and operating microscope, so the foreign body hook that self has power supply, light source and a magnifier promptly seems unnecessary.2, aseptic requirement improves, and some design complicated, have movable part, is unfavorable for cleaning with the corneal foreign body hook use that can not tolerate high-temperature sterilization repeatedly being restricted.3, bigger with ophthalmic operating set difference at present commonly used in appearance, be not easy to practical clinical.
Therefore need a kind of simple in structurely as tradition cornea foreign body hook clinically, any surface finish and tolerate high-temperature sterilization repeatedly can cooperate ophthalmology slit lamp microscope or operating microscope to use, and can adsorb the magnetic corneal foreign body of iron foreign body.
The utility model content
The purpose of this utility model provides a kind of magnetic cornea foreign body hook, the technical problem that solution just can be rejected shallow-layer irony corneal foreign body with simple tool and be struck off cornea rust ring and foreign body or the absorption of rust ring are taken out, and solve simultaneously be convenient to clean with high-temperature sterilization after the problem that can use repeatedly.
For achieving the above object, this utility model adopts following technical scheme:
A kind of magnetic cornea foreign body hook, comprise the shank that is used to hand, be used for the head that foreign body takes out and connect this two-part cervical region, it is characterized in that: the material of described shank and cervical region is the material with magnetic, the material of described head is a permanent magnet material, and described head has opposite hook end of direction and shovel end, and it is sharp keen hook-shaped that the hook end is, hook is towards shank curved, the shovel end is spatula-like, and the edge of shovel is positioned at the upper edge of head one end, and the surface between described hook end and the shovel end is a smooth surface.
Can there be parallel scrobicula line on the surface of described shank so that hand-held.
The blade sideline of described spatula is 1/6～1/4 circular arc.
The length of described shank can be 80～120mm, and diameter is 4mm.
The length of described cervical region can be 25～35mm, and diameter is 1～1.5mm.
The diameter of part can be 1.0～1.5mm between the hook of described head, the shovel two ends, and hook end length is 3mm.
The coupling part, two places of described shank and cervical region and cervical region and head is and seamlessly transits curved surface, and there is chromium coating on the surface of described head.
This utility model is compared with syringe needle or traditional cornea foreign body hook has following characteristics and effective effect:
1, having increased head has hook end and spatula end, and an end is used for rejecting and drawing the irony corneal foreign body, and the other end is used to strike off and draws the cornea rust and encircle.Striking off of cornea rust ring can be carried out easily, and the risk of damage normal cornea can be reduced.
2, head is by making than strong permanent magnet material, realized the rejecting corneal foreign body or strikes off cornea rust ring and take out a step with absorption and finish, and makes operation more simple and convenient.
3, shank is elongated, can cooperate ophthalmology slit lamp microscope or operating microscope to use, and adapts to the requirement that present ophthalmology operation and operation have entered the micro-epoch.
4, no activeness parts, whole process smoothing processing is eliminated the dead angle and is given chromium plating and handle to guarantee any surface finish, is convenient to cleanse and disinfect.
5, head is made by having more ferromagnetic material, can realize rejecting or strike off and draw a step and finish, and is therefore very convenient, safe, effective, and simple in structure.
6, the surface of head and cervical region is a smooth surface, has eliminated the dead angle, is convenient to cleaning and sterilization; No activeness parts are easy to safeguard the use of can sterilizing repeatedly.
Simultaneously, this utility model also good complete operation when handling non iron shallow-layer corneal foreign body, using method is similar with traditional non magnetic corneal foreign body, cooperate ophthalmology slit lamp microscope or operating microscope can be used for the taking-up of various common shallow-layer corneal foreign bodys, be specially adapted to the taking-up of shallow-layer irony corneal foreign body and rust ring.
