Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of ophthalmosyringe.
Background technology
The current intravitreal drug conveyer device eyelash not having retinal tissue by eyes
Vitreous body is delivered to medicine in shape body par, to avoid complication, such as retina shedding, it is desirable to
Bigger pars plana incision (such as 1-5mm), in order to implant.
Licensing to United States Patent (USP) No.4 of Bucalo, 030,499 proposes a kind of syringe, should
Syringe comprises the implant under solid state.This syringe includes being positioned at injection tube outside or note
Heating coil in shooting cylinder and relevant pin, for planting solid before being expelled to bodily tissue
Enter body and be changed into liquid.But, this coil design may cause manufacturing cost to increase and potential
Integrity problem.United States Patent (USP) No.6,488,659 licensing to Rosenman discloses
A kind of catheter with heat transfer fluid channels, for being injected into a kind of heat-sensitive gel material
Apogee in patient body.By syringe, heat-sensitive gel material is transported to catheter.Drain
Pipe makes heat-sensitive gel material keep liquid, until flowing to destination organization.But, catheter type
Medicine conveying is unsuitable for ophthalmic applications.
Some disease of ocular region is threaten vision always.Age-related macular degeneration
(ARMD), choroidal neovascularization (CNV), retinal degeneration are (such as diabetic retinopathy
Property, vitreoretinopathy), retinitis is (such as cytomegalovirus (CMV) property retina
Scorching), uveitis, macular edema, glaucoma and sacred disease be exactly some examples.Therefore
Existing and improve the needs that the medicine of ocular region carries, this improvement is not by present apparatus
Above-mentioned restriction.
But the above-mentioned operation carrying out medicine conveying in vitreous body is cumbersome, it is impossible to carry out simultaneously
Other some auxiliary operations, and give syringe more renew dosage form time be very trouble, time-consuming
Arduously.
Summary of the invention
For above-mentioned problems of the prior art, it is desirable to provide one is easy to operate,
Time saving and energy saving ophthalmosyringe.
To achieve these goals, the present invention adopts the following technical scheme that:
A kind of ophthalmosyringe, including body, protecgulum, bonnet, syringe needle, calandria, pushes away
Bar and battery.Described body front end outer side is provided with external screw thread, and described protecgulum rear inside wall sets
Female thread, described female thread and described external screw thread is had to match, so that protecgulum is dismountable close
Envelope is connected to the front end of body.Described bonnet is dismountable is located at body rear end.
Described syringe needle is self sealss rustless steel syringe needles, is provided with flow control outside described syringe needle rear end
Device processed.The rear inside of described syringe needle is provided with chuck, and the front portion of described protecgulum is provided with boss.
Described boss matches with described chuck, so that before described syringe needle is located at protecgulum securely
End.
Being provided with dividing plate in described inner body wall, chamber body is divided into calandria by described dividing plate
Chamber, pushrod chamber and battery cavities.Described calandria is located at described calandria intracavity；Described push rod can
It is located at slidably in described pushrod chamber；Described battery is located in described battery cavities.
The rear end of described push rod is provided with slide block, and described upper end of slide block is provided with push button.Described push away
Being provided with slide block slot on the sidewall of bar chamber, described slide block is arranged in slide block slot, and described push button is positioned at
Outside slide block slot, being provided with dosage form chamber in described calandria, the rear end of described calandria is provided with push rod
Hole, described push-rod hole is connected with dosage form chamber, and dosage form is stretched into through push-rod hole in described push rod front end
Intracavity.The front end of described push rod is provided with piston, can carry when described push rod slides in pushrod chamber
Dynamic piston moves at the dosage form intracavity of calandria.Dosage form is placed on the front of dosage form intracavity piston,
Including the medicine treating ophthalmic in dosage form, dosage form is low melting point dosage form, and it can carry with liquid
To eyes, and so that the amount of sustained release can be controlled drug delivery to impact point, solid at impact point
Change.
Described outer body wall is provided with temperature controller and switch, and described calandria passes through wire
It is connected with battery, temperature controller and switch.Described calandria can be to the agent of dosage form intracavity
Type heats, and makes dosage form melt for liquid, and described temperature controller is used for controlling liquid after dosage form fusing
The temperature of body dosage form.
During use, the dosage form with medicine being positioned over dosage form intracavity, open switch, switch is certainly
Dynamic connecting calandria and battery, the dosage form of dosage form intracavity is heated by calandria, makes the dosage form hot melt be
Liquid, temperature controller senses the temperature of the dosage form in controlling agent die cavity automatically, when the liquid of dosage form
When temperature arrives the maximum set, it is automatically stopped heating.
Then promote forward push button with hands, push button band movable slider moves forward in slide block slot, from
And making push rod drive piston to move forward, the liquid forms in piston then push agent die cavity is to reach
Dynamic, then by syringe needle by drug delivery to the vitreous body of ocular region, due to the length of pin
Short and self-packing character, syringe needle can be inserted into glass in the place beyond orbiculus ciliaris
In body, the least to the probability of retinal tissue large area interference.The dosage form of liquefaction is through pin
Head flows into destination organization, and starts controlledly sustained release liquid medicine dosage form entrance tissue,
After arriving destination organization, the dosage form of liquid solidifies on the target tissue.Medical personnel are from vitreous body
After taking out syringe needle, the opening self sealss that syringe needle causes.Medical personnel can be by syringe needle simultaneously
Flow controller the transporting velocity of liquid medicine dosage form is control effectively, prevent drug delivery speed
Spend fast or cross slow and make patient do not feel like oneself.
The invention have the benefit that simple in construction, easy to operate, in vitreous body, carry medicine
The whole operating process of product dosage form can be completed by a hands, and the another hands of doctor can be same
Other operation of Shi Jinhang, thus improve work efficiency.
