Part be that plastics are made, and incarceration in scleral walls and into intraocular is stainless steel, and such eye is outer and intraocular shape
Into a passage, the internal diameter of silicone tube can be more slightly larger than the intrusion pipe external diameter being exposed at outside eye, thus silicone tube can be buckled in into filling
The outer end of pipe is noted, and is contacted with conjunctivae and selerae, the other end of silicone tube is tightly connected with the nipple 3, formation one is closed
Space, then with nook closing member 4 in portable drawing syringe 1 in order to produce the negative pressure of suction.
Please continue to refer to Fig. 1 to Fig. 3.The rear portion of the syringe 1 is provided with fastener 5.The fastener 5 includes holding section 51
And the bayonet part 52 with the integrally connected of the holding section 51, the shape of the holding section 51 is consistent with the outer wall shape of syringe 1, institute
The outer wall that holding section 51 is sticked in the syringe 1 is stated, the bayonet part 52 is in disc-shaped, and the bayonet part 52 is covered on the pin
At the opening at 1 rear portion of cylinder, the bayonet socket 53 is opened on the bayonet part 52.Have between the holding section 51 and bayonet part 52
Draw-in groove 54, is provided with flange 11 at the opening at the rear portion of syringe 1, the flange 11 be edge from opening along the radial direction of syringe 1 to
Outer to extend what is formed, the flange 11 is sticked in the draw-in groove 54.Fastener of the invention 5 can ensure that it is firmly sticked in
At the opening at the rear portion of syringe 1.
In one embodiment, the internal diameter with diameter greater than the syringe 1 of the bayonet part 52 of disc-shaped.
Fig. 4 is referred to, Fig. 4 is the dimensional structure diagram of nook closing member in Fig. 1.As shown in figure 4, nook closing member of the invention 4 includes
Piston head 41 and the pull bar 42 being connected with the piston head 41, are provided with catch 43 on the pull bar 42.The catch 43
The bayonet socket 53 can be passed through by the lifting of pull bar 42.After the catch 43 passes through the bayonet socket 53, rotating sliding bar 42, institute
State catch 43 and bayonet socket 53 is staggered, catch 43 is stuck at bayonet socket 53.
In one embodiment, the pull bar 42 is solid circles, a diameter of 2-3mm of the pull bar 42.
In this embodiment, the catch 43 is two, and fits in the inwall of the syringe 1 or between the inwall of syringe 1
With interval, the silicone oil amount that the present invention can be extracted as needed adjusts the negative pressure in syringe by corresponding catch position.
The ovalize of the catch 43.In other embodiments, the catch 43 at least two.The shape of the catch can also be
The strip adaptable with the shape of the bayonet socket, such as rectangle etc..
Please continue to refer to Fig. 1, the bayonet socket 53 is bar shaped bayonet socket, and the length of the bayonet socket 53 is equal to or more than syringe 1

Footpath, bayonet socket 53 can be passed through with the catch 43 for ensuring nook closing member 4, and after the rotation of pull bar 42, catch 43 can be firm
Be stuck in outside bayonet socket 53, so as to realize the positioning to nook closing member 4.
As shown in Figures 1 to 4, when silicone oil extraction is carried out, pull bar 42 is lifted, the catch 43 for being protruded passes through the card
Mouth 53 is simultaneously pulled out from bayonet socket 53, has now produced negative pressure in syringe 1, then rotates the direction of the pull bar 42 of nook closing member 4, note
Negative pressure in emitter syringe 1 is intended to suck back nook closing member 4, and the catch 43 that now one or two has been rotated toward is stuck in and packs into just
On the bayonet part 52 of the fastener 5 at the rear portion of injector syringe 1, nook closing member 4 is thus secured, so that ensure will not be by syringe 1
Negative pressure is retracted, it is ensured that constant negative pressure.In the present invention, after catch 43 is pulled out from bayonet socket 53, the angle for rotating nook closing member 4 can
The angle for deviateing bayonet socket 53 is thought, as long as ensure that catch can be sticked in the edge of bayonet socket 53.In order to nook closing member is fixed
More firmly, the anglec of rotation is 90 ° for position.
In one embodiment, the amount of the silicone oil that can be suctioned out as needed sets position of the catch 43 in nook closing member 4, no
Situation about inhaling by mistake can be caused, so as to ensure that operation smoothly, is reliably carried out.
The present invention also provides a kind of operating method of intra-ocular silicon oil aspirator, and methods described comprises the following steps:
Step S1:After the completion of the nipple 3 of silicone tube 2 and syringe 1 is tightly connected, lifts in pull bar 42, syringe 1 and produce
Negative pressure, continues to lift pull bar 42, the catch 43 is passed through bayonet socket 53.
Step S2:Rotating sliding bar 42, makes catch 43 and bayonet socket 53 staggered, and the negative pressure in syringe 1 is by the stabilization of catch 43
Be stuck at bayonet socket 53, in order to produce suction, constant negative pressure, and then realize the extraction to silicone oil.
Step S3:After the completion of suction, rotating sliding bar 42, makes catch 43 and bayonet socket 53 corresponding again, promotes pull bar
42, the catch 43 passes through bayonet socket 53.
The silicone tube of the connection of nipple of the present invention 3 is about 5mm, coordinates minimally invasive sclera sclerotic puncture set clinically used
Pipe, by lifting syringe nook closing member, and can form certain negative pressure.By allowing nook closing member to be stuck on syringe, constant bearing is formed
Pressure, the passage that silicone oil can just be formed by sclerotic puncture sleeve pipe enters in injector syringe from vitreous chamber.
Manual intra-ocular silicon oil withdrawal device of the invention and operating method have the following advantages that:
(1) withdrawal device of the invention, it sets catch on the pull bar of nook closing member, and sets engaging at the rear portion of syringe
Part, when silicone oil is extracted, after the catch on pull bar is drawn out fastener, by rotating the direction of nook closing member, the catch and card
Mouth is staggered, and the negative pressure in injector syringe can produce suction to nook closing member, so that being stuck in card by the catch of direction of rotation
At the bayonet socket of component, nook closing member is thus secured, to ensure to be retracted by the negative pressure in syringe, it is ensured that constant negative pressure.
(2) withdrawal device of the invention, its simple structure is easy to operate, and the negative pressure that can be formed is constant, does not result in what is inhaled by mistake
Situation, so as to ensure that operation smoothly, is reliably carried out.
Described above fully discloses specific embodiment of the invention.It is pointed out that being familiar with the field
