Description
Technical field
The utility model relates to the field of medical instrument technology, in particular to intra-ocular foreign body grabbing device.
Background technique
Since the usage degree of employment security publicity and safeguard is not high, eye traumas is still the main blinding eye in China
One of disease.It is shown according to epidemiologic data, provincial hospital eye traumas patient accounts for the 15.5% of ophthalmology inpatient, in prefecture-level
Heart hospital, eye traumas account for the 34.7% of same period ophthalmology inpatient.Intra-ocular foreign body type is also varied, in addition to iron, cobalt, nickel,
The metallic foreign bodies such as copper, lead, aluminium, zinc, gold, platinum, mercury, there are also the artificial-synthetic compounds such as the minerals such as stone-coal residue, glass plastic,
The animalities foreign matters such as vegetalitas, the nail sclerotin such as branch bamboo thorn.
There are mainly three types of traditional Extraction of intraocular foreignbody devices: magnet, claw foreign body forceps, duck-beak type foreign body forceps.Magnet master
It is used to be sucked out intraocular magnetic foreign body, duck-beak type foreign body forceps are mainly used for extracing retina or wall of eyeball foreign matter, claw foreign body forceps
Bite force is good, is current using wider foreign body forceps type, but existing foreign body forceps is cutting-edge structure for the ease of crawl front end
Or tweezer pawl clamps lateral surface additional cuts sword structure, operation easily injures eye inner tissue in art.
When Extraction of intraocular foreignbody, mainly there is two o'clock requirement to foreign body forceps: clamping is firm, and foreign matter or clast are not easy to fall.When
Foreign matter surface is round and smooth, small volume is not easy to clamp or quality is more crisp frangible, and when small volume quantity is more, traditional is intraocular different
Object withdrawing device is often not easy to take only, falls flat.In foreign body process art, since it is expected that stretching out incision length
Deficiency, when needing to expand the notch secondary stretching of progress, traditional Extraction of intraocular foreignbody device is also possible to loosely lead because of crawl
Causing foreign matter to fall off causes retina secondary damage or foreign matter smaller, is also easy to happen and falls off in clamping process, may cause view
Nethike embrane secondary damage is such as cleared up not exclusively, can lead to the serious diseases complication such as entophthamia, retinal detachment, metal hemachromatosis.
Utility model content
The purpose of the utility model is to provide a kind of structure is simple, easy to operate, foreign body grabbing is firm, is not easy to fall foreign matter
Clast, convenient for improving the intra-ocular foreign body grabbing device of success rate of operation.
To achieve the goals above, the technical solution of the utility model is:
Intra-ocular foreign body grabbing device, including handle portion and clamping part, the handle portion are tube-shaped structure closed at one end,
Offer kidney slot on the outer wall of handle portion, the truncated cone-shaped that the leading portion of handle portion is diametrically gradually reduced, handle portion front end towards
Metal sleeve is laid in outer extension, and clamping part is laid in the inner cavity of handle portion, and the clamping part includes button, fixed link, three metals
Lasso trick and elastic film, one end of the button is protruded into from kidney slot is connected to fixed link side wall, adjacent two metal lasso tricks it
Between angle it is equal, the flexible film of inside stickers lining at the half of metal lasso trick front end, the elastic film is in hollow
Semielliptical shape, every metal lasso trick includes curved bend tune and straight bar section, and the end face of the straight bar section of the metal lasso trick is solid
The fixed front end face to fixed link, the inner cavity of handle portion and the inner cavity of metal sleeve are moved forward and backward for metal lasso trick, metal lasso trick
Curved bend tune is stretched out from the nozzle of metal sleeve and the extension end of three metal lasso tricks is connected to a fixed, the stretching, extension of metal lasso trick
When its curved bend tune mid diameter be greater than metal sleeve diameter.
Further, the kidney slot is located at the front end of handle portion.
Further, the length of the metal lasso trick is less than the length of handle portion.
Further, the metal lasso trick is elastic material；The front end of metal lasso trick is passivity structure.
Further, the button includes interconnecting piece and fixed part, and the interconnecting piece is cylindrical, and one end of interconnecting piece is certainly
Kidney slot protrudes into and is connected to fixed link side wall, the other end is located at the outside of handle portion, the fixed position in the outside of handle portion,
It is threadedly coupled between fixed part and interconnecting piece.
Further, array offers circular antiskid groove on the front end outer side wall of the handle portion.
The utility model has the following beneficial effects:
The front end of the utility model intra-ocular foreign body grabbing device be three metal lasso tricks, tighten lasso trick when can secure lock grab
Taking foreign body；Button, which slides back and forth, can drive metal lasso trick to be adjusted to need size, and the fixed part of button can be stretched in metal lasso trick
It is fixed out or after retracting, is convenient for operation, while avoiding protecting metal lasso trick in metal lasso trick free movement；
The elastic film of metal lasso trick front end setting, can tightly wrap up foreign matter prevents foreign matter or clast from falling, and reduces intraocular
The foreign matter secondary risk for falling damage intraocular structure when foreign body grabbing device exits, it is safe and reliable take out intraocular different shape,
Different size, all kinds of foreign matters of different nature avoid leading to entophthamia, retinal detachment, metal hemachromatosis because foreign matter is fallen
Etc. serious diseases complication；And elastic film accounts for the half of metal lasso trick arc-shaped bend section, does not influence grabbing for metal lasso trick
It is taken as industry.
The front end of metal lasso trick is passivity structure, and relatively existing foreign body forceps front end is that cutting-edge structure or tweezer pawl pincers lateral surface are attached
Add cutting edge structure safer, operation is not easy to injure eye inner tissue in art；
Array is laid with antiskid groove on the front end outer side wall of handle portion, and antiskid groove plays the role of anti-skidding, facilitates crawl
Operation；And in art, because hand is pinched in the front end of handle portion, therefore antiskid groove only is laid in the front end of handle portion more, reduce and add
Work technique.
The utility model structure is simple, and success rate of operation can be improved, and easy to operate, foreign body grabbing is firm, is not easy to fall
Foreign matter clast, convenient for improving success rate of operation, application easy to spread.
