Description
Technical field
The utility model relates to medical apparatus technical field, specially a kind of operation of ophthalmology vitreous chamber infusion art is dedicated
Syringe and injection needle.
Background technique
The development of ophthalmology vitreous chamber infusion art is very fast, has become one of most common treatment method of ophthalmology, so far
Until still not dedicated for the injection special syringe and injection needle of ophthalmology vitreous chamber infusion art, in eye procedures
In, due to injecting the very small 0.05ml-0.1ml of amount of drug, so the requirement to syringe is high, it is desirable that injection dosage will be very
Accurately, traditional syringe can not be carried out using and not suturing after injecting, it is desirable that injection needle is very thin, tradition
Common 1ml empty needle syringe needle is thicker, and postoperative eyeball airtightness cannot be guaranteed, increase the risk of infection, and simultaneously injected drug gold is expensive,
It involves a need to separate and with drug, needs syringe needle few to drug waste, the cavity between traditional injection and syringe needle
It is larger, the dosage of drug is increased, treatment cost is improved, in addition injection operation inserting needle position is located at the outer 3.5mm- of corneal limbus
4mm, injection needs assistant to measure level with a yardstick to set at present, operator can inserting needle, this just needs the cooperation of two people, and requires ruler
Precisely, human input is increased, while in injection process, the use of conventional apparatus lacks reference unit, the depth of syringe needle injection
Degree is by artificial control of operating, and the depth that syringe needle enters is not capable of fixing unification, and during medicine injection, syringe needle more holds
Easy depth variation, practicability is lower, therefore needs the operation special syringe and injection needle of a kind of ophthalmology vitreous chamber infusion art
Head.

Compared with prior art, the utility model has the beneficial effects that the operation of the ophthalmology vitreous chamber infusion art is dedicated
Syringe and injection needle are equipped with injection needle, and are provided in the place apart from needle point 3.5mm one small rectangular convex
Block, the front end of convex block is apart from needle point 3.5mm, and rear is apart from needle point 4mm so that in surgical procedure, using convex block can precisely into
Pin position reduces operation link, is not required to the position that assistant measures inserting needle, reduce human input, and do not need with special
Ophthalmology gage avoids improving operation precision because the precision problem of gage leads to inserting needle position deviation, meanwhile, utilize convex block
Can accurate depth of needle, avoid leading to depth of needle disunity because of human factor, inserting needle is too shallow, infusion of medicine eyeball parietal layer
Between, the too deep risk for haveing damage crystal again of depth of needle improves the practicability of device, injection needle 29G-30G specification is set
It sets, so that wound is small after injection, postoperative good leak tightness reduces the risk infected in ball, and injection needle and syringe lumen are solid
Fixed connection, reduces the remaining void of coupling part, and be used cooperatively with the first rubber pushing block of the second rubber pushing block side, makes
Drug waste it is few, medication amount is accurate, reduces treatment cost.
