Abstract
The present invention is a kind of instrument being applied to cataract operation, conveniently and safely ostomy to anterior capsule.Sickle is the close ring of the good plastic material of toughness, and annulus bottom is equally spaced profile of tooth projection.Filler ring is the hollow circular ring of the good plastic material of toughness, can accommodate sickle, and matched, and sickle can be freely rotatable in filler ring；There is the open zone of wide about 1.5mm filler ring bottom, and the profile of tooth projection of sickle bottom annular array is positioned at this open zone；Filler ring tail end is connected with push rod by connecting rod, by promoting push rod, by handle reservoir, connecting rod can be pushed sleeve, meanwhile, via connecting rod, be released by filler ring in sleeve.Being respectively arranged with a hole above sleeve and handle reservoir, pulling rope is passed through by space.Pulling rope one end is fixed in a profile of tooth projection of sickle, and the other end is outside handle reservoir, and end and a rope pendant are connected, and rope pendant diameter is more than hole bore above handle reservoir.Release filler ring, pull pulling rope, sickle to streak at anterior capsule, complete ostomy moulding.
Description
Technical field
The present invention relates to a kind of instrument being applied to cataract operation, conveniently and safely ostomy to anterior capsule.
Background technology
Anterior capsule is ostomy is a necessary step in cataract operation (the outer method of most widely used capsule), and its success or not is very
The success or failure of cataract operation are directly determined in big degree.Cyst membrane mouth is made well, cataract operation just success a greater part of this in industry
It is inside to know together widely, it is sufficient to seem the importance of this step.Currently used method has three kinds: method one, continuous circular shape
Capsulorhexis one uses Tweezers for eye surgery capsulorhexis.This needs sizable skill and proficiency, through zoopery many times and clinical accumulation
Just can reach certain degree, be the content of examination the most most basic to cataract patient.Even if it addition, have most through
The cataract operation doctor tested, also will not have absolute belief to success capsulorhexis, because different patients, the fragility of cyst membrane, toughness
Difference, the Maturity of crystal, whether liquefy etc. situation, all can have influence on capsulorhexis.Clinic usually occurs cyst membrane split, capsule
The complication such as film mouth is bigger than normal or less than normal.Cyst membrane splits and can directly contribute operative failure；Meeting bigger than normal causes artificial intraocular lenses to clamp,
Less than normal can reduce intraocular lens optic district effective utilization, affect the inspection to optical fundus simultaneously.There is also huge wind in this way
Dangerous, insecurity.Method two, can-opener capsulotomy mark Nang Kou with using discission needle one pin one pin.It is to skill requirement
Slightly lower compared with the former, it also requires suitable proficiency level, the most also there is huge risk because of cyst membrane, the diversity of crystal；
What is more important the method is ostomy the roundest and the most smooth, affects postoperative visual quality.The method is only for not possessing continuous curvilinear capsulotomy side
The doctor of method, or special circumstances cataract (as unstable in Suspensory ligament etc.), just can use.Method three, some apparatus are ostomy.
Also can realize cyst membrane by these apparatuses ostomy, but the cyst membrane mouth made is imperfect, easily forms gap, increase at anterior chamber pressure
Time cause cyst membrane to split, operative failure.
Summary of the invention
In order to reduce the great risk of existing cyst membrane ostomy method and be difficult to the property grasped, the present invention provides a kind of cyst membrane mouth moulding
Device, except can farthest reduce, even eliminates the risk that cyst membrane is ostomy, can also be based entirely on patient profiles simultaneously, right
The size of cyst membrane mouth accomplishes the control of individuation.
The technical solution adopted for the present invention to solve the technical problems is: include sickle, filler ring, pulling rope, connecting rod,
Sleeve, handle reservoir, push rod.Sickle is the close ring of the good plastic material of toughness, and annulus bottom is equally spaced
Profile of tooth projection.Filler ring is the hollow circular ring of the good plastic material of toughness, can accommodate sickle, and matched, cuts
Cutter can be freely rotatable in filler ring；There is the open zone of wide about 1.5mm filler ring bottom, and the profile of tooth of sickle bottom annular array is dashed forward
Rise and be positioned at this open zone；Filler ring tail end is divided a word with a hyphen at the end of a line as connecting rod, is connected with push rod, can by promote push rod and by connecting rod by handle
Container pushes sleeve, via connecting rod, is released by filler ring in sleeve meanwhile.One it is respectively arranged with above connecting rod and handle reservoir
Hole, pulling rope is passed through by hole.Pulling rope one end is fixed in a profile of tooth projection of sickle, and the other end holds at handle
Outside device, end and a rope pendant are connected, and rope pendant diameter is more than hole bore above handle reservoir.Pulling rope is in filler ring tail end and connection
Traveling in bar.Releasing filler ring, pull rope pendant, sickle streaks at anterior capsule, completes ostomy moulding.This utensil can be made disposably
Use, it is possible to repeatedly use through fumigation.
The invention has the beneficial effects as follows: (1) is not required to expand corneal incision.(2) with fixed model, anterior capsule is disposably cut
It is split into type, method safety, simple, quickly.Practice completely without complicated, also do not have conventional method to be difficult to the skill grasped.
(3) cyst membrane mouth is complete, continuous, without gap.
Accompanying drawing explanation
Accompanying drawing is side view and the top view of the present invention.
Fig. 1 is the side view (before releasing filler ring and sickle) of the present invention.
Fig. 2 is the top view (after releasing filler ring and sickle) of the present invention.

Detailed description of the invention
By corneal incision, the tip inlets of sleeve being put into anterior chamber, promotes push rod, the filler ring being positioned in sleeve and sickle are by forward
Promote.The filler ring released can revert to annular automatically.Handle reservoir front end is slightly pressed downward against, and makes the sickle pressure in release filler ring
On cyst membrane.Pulling rope pendant traction pulling rope, drive sickle to rotate, anterior capsule can be marked by the profile of tooth projection below sickle
One complete circular incision.After having cut, push rod, the filler ring outside band moving sleeve is back pulled to taper into, until all
Regain in container sleeve, withdraw from from anterior chamber, complete this operation.
Claims (1)
1. a cyst membrane mouth shaping device, includes sickle, filler ring, pulling rope, connecting rod, sleeve, handle reservoir, push rod, releases
Filler ring, pulls pulling rope, sickle to draw capsule, it is characterized in that: sickle is the close ring of the good plastic material of toughness,
Annulus bottom is equally spaced profile of tooth projection, and filler ring is the hollow circular ring of the good plastic material of toughness, can accommodate sickle,
And matched, sickle can be freely rotatable in filler ring；There are the open zone of wide about 1.5mm, sickle bottom in filler ring bottom
The profile of tooth projection of annular array is positioned at this open zone；Filler ring tail end is connected with push rod by connecting rod, can by promotion push rod incite somebody to action
Connecting rod is pushed sleeve by handle reservoir, via connecting rod, is released by filler ring in sleeve, on sleeve and handle reservoir meanwhile
Side is respectively arranged with a hole, and pulling rope is passed through by space, and pulling rope one end is fixed in a profile of tooth projection of sickle, another
End is outside handle reservoir, and end and a rope pendant are connected, and rope pendant diameter is more than hole bore above handle reservoir.
