Description

The intraocular surgery syringe

One, technical field

This utility model belongs to the medical device technical field, is a kind of a kind of synchronous notes, suction formula glass intraocular surgery syringe when being used for hospital and making intraocular surgery for patient specifically.

Two, background technology:

As everyone knows, the ocular tissue of human body is very tender and lovely, thereby to do the requirement of intraocular surgery also higher for the ophthalmic patient: the cataract capsule extracts outward, and hyphema amasss the dense and dense liquid art etc. of changing of vitreous body inner product accumulation of blood.Original single function syringe is easy to each tissue in the harmed eye to ophthalmic suction focus singlely; Can take out eyeball flat when serious; And single ground inwardly also can slightly greatly also directly influence surgical effect because of the too little pressure of eyeball volume during the eye liquid medicine injection, produces complication or sequela.

At present; There are employing in some external and domestic large hospitals such as provincial or indivedual city-level hospital " vitreous cutter " accomplish these intraocular surgeries; But the price comparison of this instrument is expensive; Also need several people compounding practice together during operation, volume is big, in use often ends operation because of machinery or the regular fault of electronic unit.

The utility model provides a kind of novel synchronization and annotate, inhale the formula syringe, promptly adopt special interior plug structure, in a syringe, synchronously accomplish simultaneously and annotate, inhale two antipodal functions of effect, thereby remain the intraocular pressure equilibrium of forces.

Three, summary of the invention

The purpose of this utility model provides a kind of inwardly ocular tissue's liquid medicine injection and carries out synchronously to keep the equilibrated novel intraocular surgery syringe of intraocular pressure with the suction focus.

For achieving the above object, the described a kind of intraocular surgery syringe of this utility model comprises injection tube (1) and injection needle (9); And with one heart, wherein piston head (2) and piston rod (3) be for being fixedly connected, and piston handle (4) and piston boit (5) are for being fixedly connected; And can move up and down, it is characterized in that:

Described injection tube (1) is a double pipe structure, constitute by outer tube (6) and interior pipe (7), wherein in pipe (7) be enclosed within the outer tube (6);

Both sides, described outer tube (6) upper end respectively are provided with a displacement slot (12), and piston handle (4) moves up and down in groove;

The described injection tube (1) that is meant with one heart; With the piston head (2), the piston rod (3) that are arranged in the interior pipe (7); And be arranged on piston handle (4), piston boit (5) in the space (8) between outer tube (6) and the interior pipe (7), same injection needle (9) is on the identical axis, and is arranged in order placement;

Described moving is meant in interior pipe (7) by a piston rod (3) is arranged, in the interior intracavity propelling flexibly up and down of interior pipe (7); Between outer tube (6) and interior pipe (7), have certain space (8), piston boit (5) advances up and down in this space (8) flexibly;

Described injection needle (9) is a double pipe structure, is made up of outer suction pipe (10) and interior comb (11).

Compared with prior art have:

1, simple in structure, easy to use;

2, in injectable drug, can aspirate the balance that can keep intraocular pressure, reduce the risk of performing the operation widely focus;

3, made things convenient for the medical personnel.

Four, description of drawings

Accompanying drawing 1 is the overall structure sketch map of this utility model;

Accompanying drawing 2 is vertical views of this utility model;

Accompanying drawing 3 is this utility model displacement slot structural representations.

Wherein: 1, injection tube 2, piston head 3, piston rod 4, piston handle

5, piston boit 6, outer tube 7, interior pipe 8, space

9, injection needle 10, outer suction pipe 11, interior comb 12, displacement slot

Five, the specific embodiment

In conjunction with accompanying drawing 1, Fig. 2, Fig. 3 embodiment is done further description, present embodiment is used for explaining this utility model, rather than this utility model is carried out any restriction.

The described a kind of intraocular surgery syringe of this utility model comprises injection tube 1 and injection needle 9, and with one heart, and wherein piston head 2 and piston rod 3 be for being fixedly connected, and piston handle 4 and piston boit 5 be for being fixedly connected, and can move up and down, and it is characterized in that:

Described injection tube 1 is a double pipe structure, constitute by outer tube 6 and interior pipe 7, wherein in pipe 7 be enclosed within the outer tube 6;

Both sides, described outer tube 6 upper end respectively are provided with a displacement slot 12, and piston handle 4 moves up and down in groove;

Described be meant injection tube 1 with one heart and be arranged in piston head 2, the piston rod 3 of pipe in 7, and be arranged on interior piston handle 4, the piston boit 5 in space 8 between outer tube 6 and the interior pipe 7, be on the identical axis with injection needle 9, and be arranged in order placement;

Described moving is meant in interior pipe 7 by a piston rod 3 is arranged, in the interior intracavity propelling flexibly up and down of interior pipe 7; Between outer tube 6 and interior pipe 7, have certain space 8, piston boit 5 advances up and down in this space 8 flexibly;

Described injection needle 9 is a double pipe structure, is made up of outer suction pipe 10 and interior comb 11.

Concrete operations are following:

Because this syringe has been taked above-mentioned sealed special interior plug structure; Thereby work as thumb and pressing piston head 2; When pushing away piston rod 3 and moving down, then in comb 11 accomplished the function of " notes ", the piston handle 4 that while forefinger and middle finger are colluding outer tube 6 outer wall both sides is in displacement slot 12; When hauling piston boit 5 and moving up, then outer suction pipe 10 has been accomplished the function of " suction ";

And when moving down piston handle 4 post-tensioning piston boits 5, then outer suction pipe 10 has been accomplished the function of " notes ", ought haul piston head 2 simultaneously, when pushing away piston rod 3 and moving up, then in comb 11 accomplished the function of " suction ".

So this utility model has reached application target simply, easily.

This utility model embodiment: when the doctor makes intraocular surgery to eye disease patient; Douche and injection when the cortex pin when example is made the wonderful enucleation of crystalline lens is inhaled flushing and hyphema empyema adopts this intraocular surgery syringe, make injection needle 9 get in the eye suitable position; With piston boit 5 post-tensioning slowly; Focus liquid gets into 8 li in outer tube 6 and the space between the interior pipe 7 of injection tubes 1 through outer suction pipe 10, and medicinal liquid then presses down from the piston rod 3 of injection tube 1, eye in flowing into through interior comb 11;

In like manner according to the needs of operation, outer 10 in suction pipe can inject when piston advanced, 11 of interior combs can suck, and made operation to the intraocular pressure balance, thereby used this syringe to reach the expection surgical effect of synchronous notes, suction dual-functional.

Operation time has not only been shortened in the independent operation freely of operator; To the stimulation of eye inner tissue, reduce postoperative complication when also having alleviated operation, thereby further improved the treatment rate of operation; This syringe volume is little; Low price, flexible and convenient to use, can be widely applied to basic hospitals at different levels.
