Abstract
This utility model is a kind of angle, viscoelastic agent room detachable needle being used for the treatment of angle closure glaucoma, it comprises pintle and pin stalk, one end of described pintle is link, the other end is connected, and pin obstructs, described pintle and pin stalk all arrange interior fluid apertures and are interconnected, be characterized in: also comprise needle point, described needle point and pin obstruct and are fixed with one, and the working end of needle point is spherical, the sphere of spherical work end arranges several flowing holes, several flowing holes obstruct with pin respectively arrange in fluid apertures be communicated with.During use, the joint first pinhead sleeve of the present utility model being connected on syringe outfan is connected, then extracts viscoelastic agent.There is the advantage that structure is simple, practical and convenient, with low cost, result of use is good.
Description
Technical field
This utility model relates to medical apparatus and instruments, is a kind of angle, viscoelastic agent room detachable needle being used for the treatment of angle closure glaucoma.
Background technology
Glaucoma is ophthalmology common disease, comprise primary glaucoma, secondary glaucoma, congenital glaucoma and mixed glaucoma, primary glaucoma is divided into again angle closure glaucoma and open angle glaucoma according to the width at angle, room, when angle-closure glaucoma ocular operation, the separation of angle, room can be carried out with injection viscoelastic agent during operation and reach the effect opened at angle, room, current Problems existing is: though the syringe needle of injection viscoelastic agent is indenting ball, but side is still sharper keen, may corneal damage endothelium or anterior lens capsule during operation, and viscoelastic agent is when being expelled to angle, room, the diffusion of viscoelastic agent is comparatively limited to, speed is slower, be unfavorable for fully expanding angle, room
.
Summary of the invention
Technical problem to be solved in the utility model is: the shortcoming overcoming prior art, the viscoelastic agent syringe needle be separated for angle-closure glaucoma eye-chamber angle that a kind of working end of needle point circle is blunt, side arranges several flowing holes is provided, corneal damage endothelium or anterior lens capsule can be avoided, accelerate viscoelastic agent diffusion velocity and range, fully expansion angle, room reaches satisfied surgical effect
.
The scheme of this utility model technical solution problem is: a kind of angle, viscoelastic agent room detachable needle being used for the treatment of angle closure glaucoma it comprise pintle and pin stalk, one end of described pintle is link, the other end is connected, and pin obstructs, described pintle and pin stalk all arrange interior fluid apertures and are interconnected, it is characterized in that: also comprise needle point, described needle point and pin obstruct and are fixed with one, the working end of needle point is spherical, the sphere of spherical work end arranges several flowing holes, several flowing holes obstruct with pin respectively arrange in fluid apertures be communicated with.
There is between described needle point and pin obstruct the angle of 130 ° ~ 140 °.
This utility model is used for the treatment of angle, the viscoelastic agent room detachable needle of angle closure glaucoma
,the spherical structure of its needle point working end can avoid corneal damage endothelium or anterior lens capsule, and several flowing holes that sphere is arranged can simultaneously to several directions injection viscoelastic agent, accelerate diffusion velocity and the range of viscoelastic agent, the angle of angle relative to original 160 ° ~ 170 ° between needle point and pin obstruct with 130 ° ~ 140 ° is more conducive to patient and operates, thus carry out the separation of angle, room more widely, reach best surgical effect, reduce the misery of patient.During use, the joint first pinhead sleeve of the present utility model being connected on syringe outfan is connected, then extracts viscoelastic agent.There is the advantage that structure is simple, practical and convenient, with low cost, result of use is good.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation being used for the treatment of angle, the viscoelastic agent room detachable needle of angle closure glaucoma of this utility model;
Fig. 2 is the close-up schematic view of Fig. 1;
Fig. 3 is the structural representation of embodiment.
In figure: 1 flowing hole, 2 needle points, fluid apertures in 3,4 pin stalks, 5 pintles, 6 joints, 7 syringes.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
With reference to Fig. 1 ~ Fig. 3, a kind of angle, viscoelastic agent room detachable needle being used for the treatment of angle closure glaucoma of this utility model, it comprises pintle 5 and pin stalk 4, one end of described pintle 5 is link, the other end is connected, and pin obstructs 4, described pintle 5 and pin stalk 4 all arrange interior fluid apertures 3 and are interconnected, also comprise needle point 2, described needle point 2 obstructs 4 with pin and is fixed with one, the working end of needle point 2 is spherical, the sphere of spherical work end arranges several flowing holes 1, several flowing holes 1 obstruct with pin respectively 4 arrange in fluid apertures 3 be communicated with.Described needle point 2 and pin obstruct the angle between 4 with 130 ° ~ 140 °.This utility model adopts prior art manufacture, and described syringe 7 is the commercially available prod of prior art.
When the present embodiment uses, the joint 6 first pinhead sleeve of the present utility model being connected on syringe 7 outfan is connected, then extracts viscoelastic agent.
This utility model is not limited to this detailed description of the invention, and to those skilled in the art, simple copy and improvement without creative work all belong to the scope that this utility model claim is protected.
