Abstract
The utility model relates to a non-magnetic intraocular foreign body aspirator for snapping the foreign body with a small diameter in the eyes, which is composed of a cannula and a push-and-pull rod assembled in the cannula in a sliding way. The bottom end of the cannula forms a seal cavity by a sealing end cap, and the side wall of the bottom of the cannula is provided with a suction port. The side wall of the push-and-pull rod is equipped with an axial suction groove, and the side wall on the top of the cannula is provided with a suction nozzle corresponding with the suction groove on the push-and-pull rod. A sealing ring is arranged between the cannula and the push-and-pull rod. Because the direction of the sealing end cap on the bottom of the cannula is parallel with the retina of human eyes and the bottom of the cannula is provided with a cambered bottom surface, which can not hurt the retina when the foreign body is snapped. The bottom of the push-and-pull rod and the corresponding end part of the cannula form a semi-closed seal cavity, making the foreign body not slip easily after sucked into the seal cavity and compressed, which greatly enhances the surgical accuracy and makes the operation convenient.
Description
Technical field
This utility model relates to a kind of intraocular nonmagnetic foreign body aspirator of ophthalmic than the minor diameter non-magnetic foreign body that be used to win, and belongs to medical apparatus.
Background technology
In the ocular injury operation, magnetic foreign body can take out by the magnetic attraction device, and non-magnetic foreign body is generally won with the non-magnetic foreign body pincers.Used non-magnetic foreign body pincers are made up of the push-pull bar of the end band pawl type folder that is slidingly installed in a sleeve pipe and the sleeve pipe in the ophthalmologic operation now, though this kind foreign body forceps can be won out with the non-magnetic foreign body of ophthalmic, but because the pawl type of push-pull bar front end folder is the narrow shape structure in preceding expansion back, foreign body comes off from pawl type folder easily, and the less non-magnetic foreign body of diameter is easier to come off from pawl type folder.The pawl type of push-pull bar folder so just is easy to injure retinal tissue directly towards retina when operating in addition, and it is very dangerous to operate, and the accuracy rate of operation is not high yet.
The utility model content
The purpose of this utility model is to provide a kind of intraocular nonmagnetic foreign body aspirator, safely and effectively the non-magnetic foreign body than minor diameter in the eyes is won out.
In order to achieve the above object, the technical solution of the utility model is to have adopted a kind of intraocular nonmagnetic foreign body aspirator, by sleeve pipe with and the push-pull bar of slides within assembling form, casing shoe forms annular seal space by an end cover, one pump orifice is arranged on the sleeve bottom sidewall, the sidewall of push-pull bar is provided with an axial suction socket, and sleeve pipe top sidewall and the corresponding suction nozzle with battery unit that is provided with of suction socket on the push-pull bar are provided with sealing ring between the sleeve pipe at sleeve pipe top and the push-pull bar.
The bottom surface of the end cover of described casing shoe is a circular arc.
Casing shoe of the present utility model forms annular seal space by an end cover, one pump orifice is arranged on the sleeve bottom sidewall, the sidewall of push-pull bar is provided with an axial suction socket, sleeve pipe top sidewall and the corresponding suction nozzle with battery unit that is provided with of suction socket on the push-pull bar, be provided with sealing ring between the sleeve pipe at sleeve pipe top and the push-pull bar, formation is by pump orifice, suction socket, the suction channel that suction nozzle with battery unit constitutes, the less foreign body of ophthalmic can be earlier by the negative pressure device that docks on the suction nozzle with battery unit the less foreign body suction seal of ophthalmic chamber, push push-pull bar again and compress foreign body, can take out foreign body from ophthalmic by this aspirator.Since parallel in the end cover direction of casing shoe with the retina in the eye, and be provided with the circular arc bottom surface, just be difficult for injuring retina when winning foreign body like this; Push-pull bar bottom and telescopic respective end form semiclosed annular seal space, foreign body be inhaled into annular seal space and compacted after be difficult for slippage, improved the accuracy of operation widely, it is convenient and swift to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, this intraocular nonmagnetic foreign body aspirator, by sleeve pipe 2 with and the push-pull bar 6 of slides within assembling form, sleeve pipe 2 bottoms form annular seal space by an end cover 4, the bottom surface of end cover 4 is a circular arc, on the sleeve pipe 2 bottom sidewalls pump orifice 5 is arranged, and the sidewall of push-pull bar 6 is provided with an axial suction socket 3, the suction socket 3 corresponding suction nozzle with battery unit 1 that are provided with on sleeve pipe 2 top sidewalls and the push-pull bar are provided with sealing ring 7 between the inwall at sleeve pipe 2 tops and the push-pull bar 6.Be connected with the suction nozzle with battery unit 1 that is provided with on a syringe and the sleeve pipe during operation, the formed negative pressure of the syringe non-magnetic foreign body that diameter is less sucks in the annular seal space of aspirator, at this moment depress push-pull bar 6 gently, non-magnetic foreign body is clipped in the cavity firmly, foreign body is taken out from ophthalmic by this aspirator.
Claims (2)
1, a kind of intraocular nonmagnetic foreign body aspirator, by sleeve pipe with and the push-pull bar of slides within assembling form, it is characterized in that: casing shoe forms annular seal space by an end cover, one pump orifice is arranged on the sleeve bottom sidewall, the sidewall of push-pull bar is provided with an axial suction socket, sleeve pipe top sidewall and the corresponding suction nozzle with battery unit that is provided with of suction socket on the push-pull bar are provided with sealing ring between the sleeve pipe at sleeve pipe top and the push-pull bar.
