Description
Technical field
The utility model belongs to technical field of medical instruments, specifically a kind of time saving and energy saving room corner separator.
Background technology
Anterior chamber angle has very important function, it be aqueous humor outflow path, if room angle is inaccessible, will make aqueous humor flow out by
Resistance, intraocular pressure is raised because of the accumulation of aqueous humor, ultimately results in the generation of glaucoma.
For glaucoma patient, it is necessary to implement room angle separating operation to it.At present, medical institutions use Syringe needle Irrigator through angle
Otch on film enters anterior chamber, is then aligned with room subscript and penetrates viscoelastic agent, but room angle is rounded, it is necessary to be turned around along the rotation of room angle
Viscoelastic agent is injected, is wasted time and energy when being injected using Syringe needle Irrigator, and is possible to omit some positions at room angle, it is right
Some positions at room angle can not be efficiently separated.
Utility model content
The technical problem existed for prior art, it is a kind of time saving and energy saving that the utility model is provided, and room angle can be entered again
The room corner separator that row is efficiently separated.
The purpose of this utility model realized by such technical scheme, and it includes the first syringe, injection head and the
Two syringes, the first syringe front end is provided with needle tubing, is in smooth arc-shaped transition between the needle tubing and the first syringe, described
Injection head is arranged in first syringe, and the injection head is in annular shape, and the injection head is made up of elastomeric material, and described the
Two syringes enter after the first syringe from the rear end of the first syringe, are fixedly connected with the outward flange of the injection head, the injection head
Outward flange be provided with multiple holes, the pore size distribution is on the whole outward flange of injection head, each syringes of Kong Junyu second
Inner chamber connection, be provided with piston in second syringe, the rear end of the piston is provided with tightening latch, and second syringe is in work
Interior intracavitary in front of plug is loaded with viscoelastic agent.
Further, the external diameter of the injection head is 8mm-10mm.
Further, the external diameter of the needle tubing is 2mm.
Further, first back end of syringe, the second back end of syringe and tightening latch rear end are provided with draw back plate.
Further, the forward end of the side wall of the needle tubing passes through arc process.
In summary, the beneficial effects of the utility model are：
1st, it is close in the cornea of patient first when the room corner separator provided using the utility model enters the separation of having sexual intercourse angle
The position at room angle carries out otch, then that needle tubing insertion otch is a bit of, pushes ahead the second syringe, the second syringe promotes injection
Head, due to being in smooth arc-shaped transition between needle tubing and the first syringe, and injection head is made up of elastomeric material, and injection head is pressed
Force deformation, can easily pass through needle tubing into intraocular anterior chamber position, injection head is annular shape, and is made up of elastomeric material,
Injection head before entry in room after can Automatic-expanding in annular shape.Then tightening latch is promoted, viscoelastic agent was entered and is distributed in injection head
Hole on outward flange is injected to room angle, so as to be separated to room angle.
Without being injected around the circle of room angle one in separation process, tightening latch is pushed directly on, a shot is with regard to that can separate one
The room angle of circle, it is time saving and energy saving；Pore size distribution on injection head will not be omitted, to room in the whole outward flange of injection head in separation
One circle at angle can be effectively separated.
2nd, the external diameter of the injection head is 8mm-10mm.Corneal diameter 11-12mm, because room angle is just in the margin location of cornea
Put, the diameter for the circle that room angle is formed also is 11-12mm, and injection head external diameter is 8mm-10mm, and room can be efficiently separated during injection
Angle, will not damage room angle because of too big again.
3rd, the external diameter of the needle tubing is 2mm.Doctor is when corneal carries out otch, and the size of general otch is 2.5mm, pin
Pipe diameter 2mm, will not both expand otch, and patient is damaged, and can conveniently operate again.
4th, first back end of syringe, the second back end of syringe and tightening latch rear end are provided with draw back plate.Draw back plate is set,
More facilitate when promoting the second syringe and tightening latch.
5th, the forward end of the side wall of the needle tubing passes through arc process.Avoid corner angle and secondary wound is caused to patient's eye
Evil.
