Abstract
The invention discloses a kind of tunnel implanted circle cutting cystoma devices for cataract operation, it is characterized in that, round cut after capsule ring folds is packed into or is pre-loaded into an injector conical nose reequiped, it is connected with cataract tunnel incision, it is sent into intraocular by injecting bar, so that the round capsule ring that cuts is unfolded, before the circle of crystalline lens central portion discharge by pressing fixed diameter after Nang Kou, bar is injected in taking-up, is recycled anterior chamber's hook that circle is cut capsule ring twice-folded and is taken out.
Description
Technical field
The present invention relates to a kind of instruments of ophthalmologic operation, can be accurately in anterior lens capsule in cataract extraction
The upper rounded sac mouth for forming fixed diameter, alternative manual continuous curvilinear capsulotomy (CCC) avoid capsulorhexis cracking in operation or tear
Capsule mouth is non-round.
Background technology
Currently, in cataract extraction, especially in excusing from death emulsification phacoerysis, continuous curvilinear capsulotomy (CCC) is
One crucial step, a high quality CCC can ensure that operation safety and surgical effect are in close relations.But presently mainly
Method by hand carries out CCC, this technology requires doctor to have skilled operation skill and abundant clinical experience, such as slightly
It is big or too small etc. unexpected that mishap will occur that capsulorhexis mouth cracking, capsulorhexis mouth is non-round, capsulorhexis mouth is not placed in the middle, capsulorhexis is made a slip of the tongue.This feelings
Condition can increase complication postoperative in operation risk and art (such as Poster capsulorhexis, suspensorium fracture, Prevention and treatment etc.)；Or it is planting
It cannot be implanted into when entering Multifocal intraocular lens (needing diameter 6.5-7mm circulars and the preceding Nang Kou of position between two parties).Therefore by hand
Implementing CCC, there are larger risks, but there is no the surgical instrument for being precisely accomplished CCC at present.CCC can be precisely accomplished at present only to tie
The femtosecond laser for leading portion positioning system of sleeping, but femtosecond laser is expensive (appraisal is 10,000,000 or so), so it is difficult to general
And.
Invention content
The drawback present in capsulorhexis is carried out for using Tweezers for eye surgery or capsulorhexis needle, the present invention provides one kind can
With help doctor accurately make it is placed in the middle, meet needed for diameter circular before Nang Kou cataract excusing from death emulsification crystalline lens inhale
Go out art instrument.
To achieve the above objectives, the present invention, which adopts the following technical scheme that, is achieved：
A kind of tunnel implanted circle cutting cystoma device for cataract operation, including injector, which is characterized in that this is injected
Device injects bar by a conical nose, a body portion, one and anterior chamber's hook forms, wherein conical nose front end and cataract
The main notch of cataract surgery matches, conical nose rear end fixture body front end, injects bar and is inserted into from body portion rear end, by one
Cutting after capsule ring pushes to anterior chamber by deformation of conical nose for positive round is extracted out；Anterior chamber's hook is inserted into from body portion rear end, is led to
Crossing conical nose will tick after section secondary deformation of capsule ring for entering anterior chamber's recovery positive round；
In said program, the connection of the conical nose rear end and body portion front end is detachable connection.In the connection side
Under formula, the advance deformation of described section of capsule ring is placed in conical nose to be connect with body portion again.
The capsule ring that cuts of the positive round is made of shape memory high molecule material or Ni-Ti memorial alloys, and a section capsule part is
Continuously arranged sharp small tooth is provided below in entire ring.
It is an advantage of the invention that the uncertainty of manual CCC can be avoided in cataract operation, in designated position shape
At the circular Nang Kou of designated diameter, operating difficulty is reduced, improves operation safety, postoperative complication is reduced, avoids performing the operation
Risk.
Description of the drawings
Below in conjunction with the accompanying drawings and specific implementation mode invention is further described in detail.
Fig. 1, Fig. 2 are implanted circle cutting cystoma device structural schematic diagrams of the present invention.Wherein Fig. 1 is to be packed into cut capsule ring (folding)
Injector；Fig. 2 is the injector for being packed into anterior chamber's hook.Fig. 3 is section capsule ring structure schematic diagram pre-installed in Fig. 1.Wherein：A figures are vertical
Body figure；B figures are side view；C figures are vertical view；D figures are folding picture.
In Fig. 1-Fig. 3:1, capsule ring (opening) is cut, 1 ', cut capsule ring (folding)；2, injector；3, conical nose；4, body portion,
5, bar is injected；6. anterior chamber's hook；7, dentalation.
Specific implementation mode
With reference to figure 1, Fig. 2, a kind of tunnel implanted circle cutting cystoma device for cataract operation, including cut capsule ring 1, inject
Device 2 and anterior chamber's hook 6.It is 6.5-7mm to cut capsule ring diameter, can be made of shape-memory polymer SMPs, such as biological base shape memory
Polyurethane (Shape Memory Polyurethane, SMPU)；Also Ni-Ti memorial alloys can be used.Cut below capsule ring is dentation knot
Structure 7 (Fig. 3), for continuously arranged sharp small tooth.Injector can be now packed into during operation by cutting capsule ring, can also be pre-loaded into injector
In conical nose.Injector includes conical nose 3, body portion 4, injects bar 5, and conical nose rear end fixture body front end is (removable
Unload), conical nose point diameter is 3.0-3.2mm, is matched with the main notch of phacoemulsification；It injects bar and is located at body
It (is inserted into from body portion rear end) in portion, forms piston structure.Anterior chamber's hook 6 be an injector outside auxiliary component, one end be it is hook-shaped,
Diameter can pass through the conical nose of injector.After bar is injected for capsule ring feeding anterior chamber will to be cut, extracted out from body portion；Anterior chamber's hook is used for
The capsule ring that cuts for cutting capsule task will be completed to take out.
The operation principle of apparatus of the present invention is as follows：
When needing to carry out CCC in cataract operation, the first step：It is packed into injector conical nose after folding and cuts capsule
Conical nose is connected with body portion, and is packed into push rod 5 (Fig. 1) by ring 1 ' (strip) and viscoelastic agent；Do cataract tunnel incision and
Auxiliary incision injects viscoelastic agent in anterior chamber, and tunnel incision is inserted into injector conical nose front end, injects strip by push rod
Sample cuts capsule ring 1 ' and enters anterior chamber；Second step：It allows section capsule ring 1 ' to be slowly launched into round section of capsule ring 1 in anterior chamber center, withdraws from and inject
Device, respectively enters Tweezers for eye surgery in tunnel incision and auxiliary incision and auxiliary hooks, mobile central position before cutting capsule ring 1 to crystalline lens
It sets, pressing cuts capsule ring 1, oppresses anterior lens capsule with dentalation 7 below, forms Nang Kou before the circle of designated diameter；
Third walks：Tweezers for eye surgery picks up preceding operculum, gently lifts and cuts capsule ring, withdraws from Tweezers for eye surgery and auxiliary hooks, again in tunnel incision interpolation
Enter injector, at this point, injector will inject bar 5 has changed anterior chamber's hook 6 (Fig. 2) into, anterior chamber is hooked into light by crook after anterior chamber
Light trigger cuts capsule ring 1, is slowly exited by injector conical nose, is withdrawn in injector after reverse folded, withdraws from injector, shape
At circular anterior lens capsule mouth, operating procedure is completed.
