Summary of the invention
This utility model provides a kind of crystal core splitting hook that is used for ophthalmologic operation that can finish the emulsifying sucking-off of nucleus lentis for solving the technical problem that exists in the known technology safety quickly.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is: a kind of crystal core splitting hook that is used for ophthalmologic operation, comprise the gib head that is used to split nuclear, described gib head is the round shovel shape, and the edge of described round shovel shape gib head is set to from inside to outside the blade of attenuate gradually.
Advantage and the good effect that the utlity model has are: gib head is set to the round shovel shape, and the edge of shovel shape gib head is provided with from inside to outside the shear blade and the side edge of attenuate gradually, helps splitting in the nuclear; By upwards obviously thickening of bottom, just as axe, the nuclear that helps riving fully separates during use; Rounding off between shear blade and the side edge is compared with common core splitting device, has reduced the disruptive danger of back cyst membrane; The gib head back side is that flat shovel is planar, and it is long-pending also to have increased the stop surface of exerting oneself to the side when splitting nuclear, effectively improves and splits nuclear efficient.And this utility model split nuclear thoroughly, grab nuclear firmly, can make and all operate in lesser ring of Merkel and carry out, super newborn syringe needle is relatively away from cornea, iris, back cyst membrane and continuous curvilinear capsulotomy mouth edge, the patient can use higher relatively ultrasonic energy emulsifying nuclear piece safely under direct-view, finish the emulsifying sucking-off of nucleus lentis safety quickly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, shovel shape gib head, 1-1, side edge, 1-2, shear blade.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of crystal core splitting hook that is used for ophthalmologic operation of this utility model comprises the gib head 1 that is used to split nuclear, and described gib head 1 is the round shovel shape, and the edge of described round shovel shape gib head 1 is set to from inside to outside the blade of attenuate gradually, that is, and and shear blade 1-1, side edge 1-2.The length of gib head 1 is 1.3mm in the present embodiment, and width is 0.6mm, and round shovel shape circumferential thickness is: 0.08mm.
The kernel method of splitting of the present utility model:
In the super newborn attraction of optical axis district high negative pressure, the ultrasonic emulsification syringe needle is deep into the center of nucleus lentis and nucleus lentis is fixed, this utility model is thrust nucleus lentis vertically downward in ultrasonic emulsification syringe needle front side, and core splitting hook and ultrasonic emulsification syringe needle are respectively to the both sides nucleus lentis of slowly riving.Again with ultrasonic emulsification syringe needle inclined-plane towards 1/2 cross section nuclear central part, the emulsifying syringe needle is imbedded in the nuclear, the rotation nucleus lentis its ambitus is exposed to lesser ring of Merkel, utilize side edge of the present utility model to examine and progressively split broken emulsifying sucking-off.
Superiority of the present utility model is:
(1) safety:
A, need not cutting and the rotation nucleus lentis, reduce tractive to Suspensory ligament and back cyst membrane;
B, whole operation are all carried out under lesser ring of Merkel is visual, and super nipple is relatively away from cornea, iris, back cyst membrane and continuous curvilinear capsulotomy mouth edge;
Even the c core splitting hook contacts with the back cyst membrane, because impetus is a wire cross section, but not a point (common core splitting hook) has reduced pressure, and is safer relatively to the back cyst membrane;
D, ultrasonic emulsification process be simple and fast more, has shortened ultrasonic energy release time within the eye, reduces complication in the art;
(2) high efficiency:
A, directly split the nuclear ultrasonic emulsification, need not carry out the operation of channeling and rotation nucleus lentis;
B, three exterior rim all can effectively be split nuclear: shear blade is like " axe " when vertically splitting nuclear, and easier wire is split nuclear, and side edge can be split nuclear along the nuclear piece longitudinal axis like " cutter " when handling the nuclear piece; Flat " back-off face " can increase stop surface when splitting nuclear long-pending;
C, when handling soft nuclear, " face " is than " line " the easier soft nucleus lentis of riving;
D, super newborn needle slope easily form complete stifled state towards nuclear piece direction, start peak negative pressure rapidly, and fixedly nucleus lentis is more firm, reduces the operation in the nucleus lentis ambitus.
In a word, this utility model can obviously shorten the ultrasonic emulsification time, alleviates after-operation response, obviously reduces complication in the art, and is particularly more apparent to less, the complicated cataract operation effect of harder nucleus lentis, pupil.
