The iris fixing device and the iris fixing method can effectively expand a pupil and reduce damages to eye tissues during a surgery process.
Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of iris fixture and iris fixing means.
Background technology
In ophthalmic diagnosis and treatment, need to operate the visual field fully, especially for cataractopiesis or the ophthalmology such as the vitrectomy operation relating to optical fundus, loose large pupil and stable iris are to provide sufficient surgical field of view, complete the necessary guarantee of ophtalmic treatments smoothly, but, pathologic microcoria or synechia usually be there will be for the patient with diseases such as iridocyclitis, glaucoma, diabetes, are difficult to fall apart large pupil with medicine; Relax for iris the patient of syndrome, and iris waves in anterior chamber, affects operation technique, easily accidentally injures ophthalmic normal structure, cause serious complication, the clinical efficacy of impact treatment.
Mainly contain for the method expanding pupil and fixing iris at present: in anterior chamber, inject that viscoelastic agent directly expands pupil, iris tension force cuts, multiple spot iris sphincter muscle cuts off, existing method expands the limited use of pupil and fixing iris, and easily cause bleeding and inflammatory reaction, cause pupil owe circle and sphincter pupillae tear, cause postoperative pupil shape irregular or be tension-free state.
Also someone adopts elasticity iris hooks to expand pupil, but iris hooks also has the following disadvantages: 1, iris hooks is to the single-point tractive of iris edge, that pulls open is limited in scope, and drag hook must accurately be positioned on orthogonal warp respectively, could form comparatively ideal pupil shape like this, otherwise by the shape of distortions such as being rectangle, trapezoidal, cause unnecessary sphincter pupillae damage, effectively cannot expand surgical field of view.2, need to place at the cut-out of limbus corneae of different azimuth that 3-4 iris hooks is even more just can be completed, the time both having extended operation turn increases the damage of operative incision source property.
Summary of the invention
Based on this, the invention reside in the defect overcoming prior art, provide a kind of iris fixture and iris fixing means, the present invention effectively can expand pupil, reduces the damage to part tissue of eye in operation process.
Its technical scheme is as follows:
A kind of iris fixture, comprise shank, slide core and fixed part, in shank, there is sliding cavity, what slide core was slided is arranged in sliding cavity, fixed position is in the front end of slide core, and curved round, fixed part has first end and the second end, at least first end is connected with the front end of slide core, and the outside of fixed part has the stationary plane of indent.
Its further technical scheme is:
Second end of described fixed part is unsettled.
Or the second end of described fixed part is connected with the front end of described slide core simultaneously.
Or the second end of described fixed part is connected with the front end of described shank.
The inner side of described fixed part is also provided with the stationary plane of indent.
In described fixed part, be provided with the fluid passage communicated with outside, described fixed part is provided with the liquid outlet communicated with fluid passage.
A kind of iris fixing means, the method comprises the steps:
A, shank is pushed iris pupil edge;
B, by slide core relative to shank forward end advance, fixed part opens, and iris struts by the stationary plane of fixed part;
C, carry out operated eye, perform the operation complete, slide core slipped in sliding cavity, fixed part folds rear taking-up.
In the step C, infusion liquid or visco-elastic material is inputted by the fluid passage of fixed part to eye.
Below the advantage of preceding solution or principle are described:
1, before the procedure, slide core is slided to the back-end relative to shank, and fixed part shrinks in sliding cavity, during operation, shank is pushed iris pupil edge, then slide core is advanced relative to shank forward end, and fixed part is opened, iris struts by the stationary plane of fixed part, surgical field of view is open, decreases the damage to part tissue of eye, performs the operation complete, slip in sliding cavity by slide core again, fixed part folds rear taking-up.
2, the structure of fixed part can be following three kinds: the second end of described fixed part is unsettled, or the second end of described fixed part is connected with the front end of described slide core simultaneously, or the second end of described fixed part is connected with the front end of described shank.
3, in described fixed part, be provided with the fluid passage communicated with outside, infusion liquid or visco-elastic material can be inputted to eye by this fluid passage, without the need to repeatedly entering anterior chamber from main otch, thus make anterior chamber and pouch more stable, reduce the traction force to apparatus suspensorius lentis.

Detailed description of the invention
Below embodiments of the invention are described in detail:
Embodiment one
As shown in Figure 1 and Figure 2, a kind of iris fixture, comprise shank 10, slide core 20 and fixed part 30, have sliding cavity in shank 10, what slide core 20 was slided is arranged in sliding cavity, and fixed part 30 is positioned at the front end of slide core 20, and curved round, fixed part 30 has first end and the second end, and first end is connected with the front end of slide core 20, and the outside of fixed part 30 has the stationary plane 31 of indent.
Wherein, the second end of described fixed part 30 is unsettled, is provided with the fluid passage 32 communicated with outside in described fixed part 30, and described fixed part 30 is provided with the liquid outlet 33 communicated with fluid passage 32.
The iris fixing means that the present embodiment adopts comprises the steps:
