Description
Technical field
The utility model is related to medical instrument articles for use, more particularly to a kind of cataract therapy device.
Background technology
Cataract refers to intraocular crystalline lens and muddiness occurs, becomes opaque by transparent, and light is hindered to enter intraocular, to
It affects vision, early stage muddy slight or range does not affect vision when smaller, is then gradually weighed out to and significantly affects eyesight even mistake
It is bright.Currently, phacoemulsification is small with notch, wound is small, restores the features such as fast, becomes the advanced cataract generally acknowledged in the world and control
Treatment method, in two steps when being performed the operation, the first step extract muddy crystal, second step implantable artificial crystal.
The notch for being a 1.8mm-3mm when first step on eyes first, by this small notch, doctor is inserted into one
Crystalline lens that is muddy, being hardened is divided into fritter, is allowed to the shape liquid that chylifies, then pass through vacuum suction by phacoemulsification needle
These fritters are sucked out mode, then inject viscoelastic agent in anterior chamber, pouch are filled, then traditional polisher is stretched by lateral incision
Pouch strikes off the epithelial cell on anterior capsule, uses mechanical friction method on Lens capsular surface, is polished to Lens capsular,
I/A injection aspirator syringe needles are finally stretched by pouch by main notch again, the epithelial cell that will be polished off by way of vacuum suction
It is sucked out with remaining cortex or is directly directly carrying out the polishing under preceding capsule, but this after absorbing remaining cortex with I/A injection aspirators syringe needle
Sample can lead to main notch oedema, and astigmatism is caused to increase.In entire cataract operation, polishing is an extremely important step, is used
In preventing and mitigate inverse position method, when polishing if epithelial cell residual is excessive, it is easy to generate inverse position method.With implantation
The more and more high-end change of artificial lens, such as three focus crystal, electrodeless zoom crystal etc., present cataract operation are not only to go
Except muddy crystalline lens improves eyesight, also emphasize it is postoperative to have better visual quality, therefore polishing is wanted in surgical procedure
It asks also higher and higher, and traditional polisher and first throws the static polishing method inhaled afterwards and also increasingly can not meet people to vision
The requirement of quality.
Invention content
The utility model provides a kind of cataract dynamic polishing absorption device to overcome the shortcomings of background above technology.
The utility model is to be achieved through the following technical solutions：

Two parts are described in detail.
Water filling part includes a water filling syringe needle 2, has a passivity scarf 4 in 2 front end of water filling syringe needle, passivity scarf 4
Design is that water filling syringe needle 2 is easy to stretch into pouch and does not damage pouch from lateral incision for convenience.The socket one of 2 rear end of water filling syringe needle is soft
Pipe 5,5 other end of hose are connect with an infusion device 6, and infusion device 6 is used to convey liquid to water filling syringe needle 2, and infusion device 6 can
Think our common infusion bottles or infusion bag, or other common delivery devices, in the protection of the utility model
In range.
It includes a polishing syringe needle 3 that part is absorbed in polishing, and the polishing fixation of syringe needle 3 is connected on one handle 1, in 1 inside of handle
Sky, both ends open, 1 other end of handle are connect by hose 5 with a vacuum extractor 12, and vacuum extractor 12 is that hospital is common
Medical instrument here no longer repeats vacuum extractor 12.Above-mentioned 3 inner hollow of polishing syringe needle, is divided into straight part 7
With the bending part 8 being folded upward at, and rounding off between straight part 7 and bending part 8, straight part 7 and dogleg section
Between angle it is best between 140 ° -155 °, convenient that preceding capsule and rear capsule are polished, the preferred straight part of the present embodiment 7
Angle between dogleg section is 150 °.The top integrally connected rubbing head 9 of bending part 8, the inner hollow of rubbing head 9,
It is communicated with inside straight part 7 and bending part 8, polishes and also communicated inside syringe needle 3 and hollow handle 1.In the upper table of rubbing head 9
Face sets a trepanning 10, and 10 diameter of trepanning is preferred between 0.2-0.3mm, 10 a diameter of 0.3mm of the present embodiment preferred aperture, polishing
First 9 lower surface is frosting 11.
