Abstract
The utility model relates to the technical field of medical apparatus and instruments, in particular to a corneal foreign body removing device used for treating corneal foreign bodies, especially for treating corneal siderosis; the corneal foreign body removing device includes a disposable skin-test needle (1), an elastic water storage bag (2) and a connecting pipe (3); the needle point part of the disposable skin-test needle (1) is in slant shape, the tip at the front end of the needle point part is in extrophia hook shape, and the disposable skin-test needle (1) is communicated with the elastic water storage bag (2) through the connecting pipe (3). The elastic water storage bag (2) is a globose water storage sag made from silica gel material. An angle of 80 DEG is formed between the tip of the needle point with the extrophia hook shape and a needle bar. The corneal foreign body removing device is characterized by simple structure, convenient operation, little damage to the corneal tissue, and so on, and can remove corneal foreign bodies and carry out washing, cleaning and preventing infection simultaneously.
Description
Technical field
This utility model relates to a kind of technical field of medical instruments, and specifically a kind of corneal foreign body that is used for the treatment of is particularly treated the corneal foreign body extractor of cornea rust calmness.
Background technology
In the taking-up treatment of corneal foreign body, mainly use disposable skin-test needle, when taking foreign body at present, the outside picking of needle point, bigger to normal tissue injury, and at the picking foreign body simultaneously, longer because of pintle, one-handed performance is dumb, can not wash foreign body and cleaning wound surface simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to operate, can wash and clean when taking out corneal foreign body, reduces the corneal foreign body extractor of cornea tissue damage.
The technical solution adopted in the utility model is: a kind of corneal foreign body extractor, it is characterized in that: comprise disposable skin-test needle, elasticity water reservoir, connection tube, the needle tip of described disposable skin-test needle is skewed, the tip of its front end is hook-shaped for turning up, and disposable skin-test needle is communicated with the elasticity water reservoir by connection tube.
The spherical water reservoir that described elasticity water reservoir is made for the silica gel material.
Described needle point tip of turning up hook-shaped and shank are 80 degree angles.
Since this utility model with the needle point of disposable skin-test needle make turn up hook-shaped, just be not easy to damage circumcorneal tissue when utilizing needle point to hook up corneal foreign body like this, disposable skin-test needle is connected with the elasticity water reservoir by connection tube, just can when getting corneal foreign body, washes and clean.
Description of drawings
Fig. 1 is a sketch map of the present utility model
The specific embodiment
Fig. 1 is a kind of embodiment of the present utility model, comprise disposable skin-test needle 1, elasticity water reservoir 2, connection tube 3, the needle tip of described disposable skin-test needle 1 is skewed, its needle point tip foremost is turns up hook-shapedly, and needle point tip of turning up hook-shaped of the present utility model is general to be 80 with shank and to spend about angles.Disposable skin-test needle 1 is communicated with elasticity water reservoir 2 by connection tube 3.Described elasticity water reservoir 2 can be the spherical water reservoir 2 that the silica gel material is made, and also can make for other elastic material.Elasticity water reservoir 2 interior can pack into normal saline, antibiotic or anaesthetics use for patient's different situations.
When using this utility model, generally be under slit lamp microscope, to operate, extruding elasticity water reservoir 2 when rejecting patient's corneal foreign body, liquid in the water reservoir 2 is flowed out from the needle point of disposable skin-test needle 1 affected part is washed and sterilized, can also prevent bitot's patches and infection simultaneously.
Thus or see, the utlity model has simple in structurely, easy to operate, characteristics such as easy damaged cornea tissue not can be washed when taking out corneal foreign body, cleaning and prevention infection.
Claims (3)
