Abstract
This utility model belongs to medical instruments field, is specifically related to the paracentesis of anterior chamber tapping pin that the operation of a kind of ophthalmology uses.It is made up of syringe needle, stop, rubber stopper, pintle, knob, needle tubing.When carrying out the tapping of ophthalmology paracentesis of anterior chamber, stop can control the degree of depth that syringe needle enters anterior chamber, avoids entering deeply, thus causes the damage of eye inner tissue, and can fix eyeball to a certain extent, is convenient to operate; Manual knob can the discharge of fixing quantity aqueous humor and the rate of outflow, intraocular pressure is slowly declined, is conducive to maintaining the stable of anterior chamber; Airtight system can avoid anterior chamber and extraneous traffic, reduces and infects probability.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to the paracentesis of anterior chamber tapping pin that the operation of a kind of ophthalmology uses.
Background technology
The paracentesis of anterior chamber tapping of eye is the store period that ophthalmology is conventional, by paracentesis of anterior chamber tapping, its objective is reduction intraocular pressure, or collection aqueous humor carries out antibacterial culturing etc.At present the syringe needle of 1ml syringe that adopts carries out this operation more clinically, and the shortcoming of this kind of way is poor patient compliance and in the unskilled situation of operator, very easily causes the damage of eye inner tissue; Discharge and the rate of outflow of aqueous humor are uncontrollable, easily cause the instability of anterior chamber, even cause obliteratio camerae anterior; Anterior chamber and extraneous traffic, easily cause intraocular infection.
Summary of the invention
Main purpose of the present utility model is to provide a kind of paracentesis of anterior chamber tapping pin.This new anterior chamber tap pin can limit the degree of depth that syringe needle enters anterior chamber, and can control discharge and the rate of outflow of aqueous humor, can also avoid anterior chamber and extraneous traffic, reduces and infects probability.
The technical solution of the utility model is: it is made up of syringe needle, stop, rubber stopper, pintle, knob, needle tubing.Wherein, needle tip is an inclined-plane, and 2mm place, rear portion, inclined-plane arranges one perpendicular to the stop of syringe needle, enters the degree of depth of anterior chamber, and can fix eyeball in order to limit needle tip.Be provided with rubber stopper and pintle in needle tubing, be interconnected both it, can in needle tubing slide anteroposterior.Arrange a circular knob in needle tubing side, it is connected with pintle, rotates this knob and can control pintle and rubber stopper slowly slides backward in needle tubing, utilizes vacuum suction to go out liquid in anterior chamber.Indicate scale at the opposite side of needle tubing, the amount of liquid in needle tubing can be measured.
The beneficial effects of the utility model are: when carrying out the tapping of ophthalmology paracentesis of anterior chamber, and stop can control the degree of depth that syringe needle enters anterior chamber, avoid entering deeply, thus cause the damage of eye inner tissue, and can fix eyeball to a certain extent, are convenient to operate; Manual knob can the discharge of fixing quantity aqueous humor and the rate of outflow, intraocular pressure is slowly declined, is conducive to maintaining the stable of anterior chamber; Airtight system can avoid anterior chamber and extraneous traffic, reduces and infects probability.
