Abstract
The utility model relates to an extracting forceps for the nonmagnetic extraneous matter in eyes, two claws at the clamping position at the front end of the extracting forceps are buckled with each other to form a scoop structure. The inner concave surface of the claws is provided with antiskid lines. Because the front end of the claws are designed into a bucked scoop structure, the picked extraneous matter in eyes is bucked and can't be pulled away, therefore the utility model can pick the nonmagnetic extraneous matters of any size in eyes conveniently and reliably. Besides, the bucked scoop structure has sphere outer surface, which is hard to hurt the tissues in eyes and is safer. The utility model has simple design and unique structure, which can improve the success rate of the operation, and the operation is very convenient and reliable, is easy for promotion and application.
Description
Technical field
This utility model relates to a kind of intraocular nonmagnetic foreign body taking-up tweezer that is used to win any size diameter non-magnetic foreign body of ophthalmic, belongs to medical apparatus.
Background technology
In the medical treatment, it is a kind of serious ocular injury that ophthalmic enters foreign body, the foreign body that takes out ophthalmic be this class ocular injury of treatment the most basic also be a most key link, because eye inner tissue is very meticulous and complicated, in order to preserve vision to greatest extent, seek out in the process of foreign body and can not cause any new damage, so very high the requirement of operating theater instruments to eye inner tissue.Generally in operation, can pass through direct sucking-off of Magnet or the sucking-off of bar magnet relay method to winning of magnetic foreign body; The apparatuses such as then mainly using foreign body forceps, foreign body forceps, foreign body pawl of winning for non-magnetic foreign body.At present, to the foreign body forceps of winning clinical practice of non-magnetic foreign body (pincers, pawl) all exist opening less, can't the larger-diameter non-magnetic foreign body of gripping, do not have shortcomings such as preventing foreign body slippage function, the success rate of operation is very low, has all brought a lot of troubles in the operating process patient and doctor.
The content of utility model
The purpose of this utility model is to provide a kind of ophthalmic of can winning safely and effectively big or take out tweezer than the intraocular nonmagnetic foreign body of minor diameter non-magnetic foreign body.
In order to achieve the above object, this utility model has adopted a kind of intraocular nonmagnetic foreign body to take out tweezer, and two tweezer pawls of the front end retaining part of this taking-up tweezer are the spoon shape structure of mutual make-up.
Because the Front-end Design of tweezer pawl is the spoon shape structure of mutual make-up, can not deviate from after intraocular foreign body is dipped, fastens, and can make things convenient for, win reliably the ophthalmic non-magnetic foreign body of size arbitrarily when operation.In addition, it is the spherical outer surface that spoon shape structure fastens the back, is difficult for injuring eye inner tissue during operation, relatively safety.This utility model simplicity of design, the structure uniqueness can improve the success rate of operation, and it is convenient and reliable to operate, and is easy to apply.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Intraocular nonmagnetic foreign body as shown in Figure 1 takes out tweezer, is made up of the tweezer pawl 3 of handle 1, rotating shaft 2 and handle front end, and handle 1 is for rigid material is made, and two tweezer pawls of the front end retaining part of tweezer are the spoon shape structure of mutual make-up.In the present embodiment, the length of tweezer pawl 3 is 24mm, and the diameter at the place, maximum cross-section of spoon shape structure is 1.2mm, and the tweezer pawl 3 of two handles 1 and handle front end rotates by rotating shaft 2 and is assembled together.
Claims (1)
1, a kind of intraocular nonmagnetic foreign body takes out tweezer, it is characterized in that: two tweezer pawls of the front end retaining part of this taking-up tweezer are the spoon shape structure of mutual make-up.
