Abstract
This utility model relates to a kind of cyst membrane mouth shaping device, can be convenient and ostomy to anterior capsule safely.Sickle is the close ring of the good plastics quality of toughness, the annulus bottom profile of tooth projection that is equally spaced.Filler ring is the hollow circular ring of the good plastics quality of toughness, can hold sickle, and match with it, and sickle can freely rotate 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, can connecting rod be pushed to sleeve by handle container by promoting push rod,, via connecting rod, filler ring is released in sleeve meanwhile.Respectively there is a hole sleeve and handle container top, and pulling rope passes through in space.Pulling rope one end is fixed in a profile of tooth projection of sickle, and the other end is outside handle container, and end is connected with a rope pendant, and rope pendant diameter is greater than handle container top hole bore.Release filler ring, pull pulling rope, sickle streaks at anterior capsule, completes ostomy moulding.
Description
Technical field
This utility model relates to a kind of instrument that is applied to cataract operation, convenient and ostomy to anterior capsule safely.
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 directly determines the success or failure of cataract operation to a great extent.Cyst membrane mouth is made well, cataract operation just success a greater part of-this is in the field of business is to know together widely, the importance of this step this fully shows.Currently used method has three kinds: method one, continuous curvilinear capsulotomy---use Tweezers for eye surgery capsulorhexis.This needs sizable skill and proficiency, through zoopery and clinical accumulation many times, just can reach certain degree, is at present both at home and abroad to the most basic content of examination of cataract patient.In addition, even if the most experienced cataract operation doctor can not have absolute belief to successful capsulorhexis yet, because different patients, the fragility of cyst membrane, toughness are different, and the Maturity of crystal, the situation that whether liquefies etc., all can have influence on capsulorhexis.In clinical, usually there is the complication such as cyst membrane splits, cyst membrane mouth is bigger than normal or less than normal.Cyst membrane splits and can directly cause operative failure; Meeting bigger than normal causes artificial intraocular lenses to clamp, and meeting less than normal reduces intraocular lens optic district effective utilization, affects the inspection to optical fundus simultaneously.So also there is huge risk, insecurity in the method.Method two, can opening formula are cut capsule---and use discission needle one pin one pin and mark Nang Kou.It requires slightly low compared with the former to skill, but also needs suitable proficiency level, equally also because of the diversity of cyst membrane, product body, has huge risk; What is more important the method is ostomy not round and smooth, affects postoperative visual quality.The method is only for the doctor who does not possess continuous curvilinear capsulotomy method, or special circumstances cataract (as unstable in Suspensory ligament etc.), just can use.Method three, some apparatus are ostomy.By these apparatuses, also can realize cyst membrane ostomy, but the cyst membrane mouth of making is imperfect, easily forms gap, when anterior chamber's pressure increases, causes that cyst membrane splits, operative failure.
Summary of the invention
In order to reduce the great risk of the ostomy method of existing cyst membrane and to be difficult for the property grasped, this utility model provides a kind of cyst membrane mouth shaping device, except farthest reducing or even eliminate the ostomy risk of cyst membrane, can also, completely according to patient's situation, to the size of cyst membrane mouth, accomplish the control of individuation simultaneously.
This utility model solves the technical scheme that its technical problem adopts: include sickle, filler ring, pulling rope, connecting rod, sleeve, handle container, push rod.Sickle is the close ring of the good plastics quality of toughness, and there is a sharp keen profile of tooth projection annulus bottom at interval of 2mm.Filler ring is the hollow circular ring of the good plastics quality of toughness, can hold sickle, and match with it, and sickle can freely rotate 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 divided a word with a hyphen at the end of a line as connecting rod, is connected with push rod, can connecting rod be pushed to sleeve by handle container by promoting push rod,, via connecting rod, filler ring is released in sleeve meanwhile.Respectively there is a hole connecting rod and handle container top, and pulling rope passes through in hole.Pulling rope one end is fixed in a profile of tooth projection of sickle, and the other end is outside handle container, and end is connected with a rope pendant, and rope pendant diameter is greater than handle container top hole bore.Pulling rope traveling in filler ring tail end and connecting rod.Release filler ring, pull rope pendant, sickle streaks at anterior capsule, completes ostomy moulding.This utensil can be done disposable use, also can be repeatedly used through fumigation.
The beneficial effects of the utility model are: (1) does not need to expand corneal incision.(2) with fixed model, anterior capsule is carried out to disposable incision molding, method safety, simple, quick.Do not need complicated practicing completely, do not have conventional method to be difficult to the skill of grasping yet.(3) cyst membrane mouth is complete, continuous, without gap.
Accompanying drawing explanation
Accompanying drawing is side view of the present utility model and upward view.
Fig. 1 is side view of the present utility model (releasing before filler ring and sickle).
Fig. 2 is upward view of the present utility model (releasing after filler ring and sickle).
1. the 2. 3. 4. 5. 6. 7. 8. 9. connecting rod pendant of 10. restricting of connecting rod top hole of handle container top hole of pulling rope of handle container of profile of tooth projection (one of them projection is connected with pulling rope) of sickle of filler ring of sleeve
push rod
The specific embodiment
The most advanced and sophisticated opening of sleeve is put into anterior chamber by corneal incision, promote push rod, the filler ring and the sickle that are arranged in sleeve are pushed forward.The filler ring of releasing can revert to annular automatically.Handle container front end is slightly to pressing down, and the sickle that makes to release in filler ring is pressed on cyst membrane.Pull rope pendant traction pulling rope, drive sickle rotation, the profile of tooth projection of sickle below can mark anterior capsule a complete circular incision.After having cut, back pull push rod, with the filler ring outside moving sleeve, diminish gradually, until all regain in container sleeve, from anterior chamber, withdraw from, complete this operation.
Claims (1)
1. a cyst membrane mouth shaping device, include sickle, filler ring, pulling rope, connecting rod, sleeve, handle container, push rod, release filler ring, pull pulling rope, sickle is drawn capsule, it is characterized in that: sickle is the close ring of the good plastics quality of toughness, there is a sharp keen profile of tooth projection annulus bottom at interval of 2mm, and filler ring is the hollow circular ring of the good plastics quality of toughness, can hold sickle, and match with it, sickle can freely rotate 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, can connecting rod be pushed to sleeve by handle container by promoting push rod, meanwhile, via connecting rod, filler ring is released in sleeve, respectively there is a hole sleeve and handle container top, pulling rope passes through in space, and pulling rope one end is fixed in a profile of tooth projection of sickle, and the other end is outside handle container, end is connected with a rope pendant, and rope pendant diameter is greater than handle container top hole bore.
