Description
Technical field
The present invention relates to ophthalmologic operation equipment technology field, in particular to a crowd can reduce the iris of corneal incision wound
Extension fixture.
Background technique
In art in order to minimize cataract extraction initiation and postoperative complications, surgeon must be as optimally as possible
Observe eye inner tissue.May exist and encounter the occasion of microcoria, such as strip off, posterior synechia, using miotic or grape
In the case that film is scorching.For cataract extraction, if cannot suitably expand pupil, there are following risks: iris
Damage, the incomplete suction of lens fragments and cortical material, rear capsule damage, capsulorhexis of trading off, Prevention and treatment and core fall
Enter in vitreous chamber.
As shown in figure 4, expansion iris needs cut 4 corneal incision 3-1b on cornea 3b in the prior art, cornea is cut
Mouth wound is larger.
Therefore, it is necessary to be improved to solve the above technical problems to the prior art.
Summary of the invention
In view of this, the purpose of the present invention is to provide the iris extension fixture that one kind can reduce corneal incision wound, it can
The wound of corneal incision when reducing iris expansion.It is realized in particular by following technical scheme:
The iris extension fixture for reducing corneal incision wound of the invention, including the side n shape closed loop, n >=4 and n are integer；It is described
It is mutually hinged between all adjacent both sides of the side n shape closed loop, the side n shape closed loop is deformed into convenient for by corneal incision
Contraction state or the expansion state that iris can be expanded.
It further include for being sleeved on the movable sleeve being in outside the side the n shape closed loop of contraction state in optimal technical scheme
Pipe.
In optimal technical scheme, the side the n shape closed loop is the equal quadrangle closed loop of each edge.
In optimal technical scheme, the adjacent both sides of the quadrangle closed loop are hinged by articulated shaft and hinge hole, articulated shaft
Mutually matched axial raised line and groove are provided between hinge hole.
In optimal technical scheme, the articulated shaft and hinge hole are made of polyacrylate material.
It is flat convenient for what is avoided mutually when contraction state in optimal technical scheme, on the inside of each edge of the quadrangle closed loop
Face shape.
In optimal technical scheme, cross section is convenient for the concave surface of fixed iris edge on the outside of each edge of the quadrangle closed loop
" C " type inwardly.
In optimal technical scheme, on the outside of each edge of the quadrangle closed loop in optimal technical scheme, the drag hook hole is set
Set the outer middle side part in each edge of the quadrangle closed loop.
Beneficial effects of the present invention: the iris extension fixture for reducing corneal incision wound of the invention uses Shi Kezhi
The main corneal incision that must be done in the operation of diameter about 3mm on cornea was connected, it is one that the side n shape closed loop, which is in contraction state,
A diamond shape, cut into cornea from cornea be deformed into expansion state become square, iris can be expanded.Relative to
Conventional iris extension fixture cannot be used for the main corneal incision that must be done in operation, and need additionally to do 4 corneas during surgery
For notch, corneal wound is less, and safer.
Other beneficial effects of the invention will be further detailed in conjunction with embodiment in detail below.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of contraction state of the present invention；
Fig. 2 is the structural schematic diagram of expansion state of the present invention；
Fig. 3 is the structural schematic diagram on quadrangle closed loop wherein one side；
Fig. 4 is the right view of Fig. 3；
Fig. 5 is the corneal incision structural schematic diagram that expansion iris needs in the prior art.
Specific embodiment
The iris extension fixture for reducing corneal incision wound in the present embodiment, including the side n shape closed loop, n >=4 and n is
Integer；It is mutually hinged between all adjacent both sides of the side n shape closed loop, the side n shape closed loop is deformed into convenient for passing through
The contraction state 1 of corneal incision 3-1 or the expansion state 1a that iris can be expanded.
The present invention using when the main corneal incision 3- that can must do in the operation directly by diameter about 3mm on cornea
It is a diamond shape that 1, n side shape closed loop, which is in contraction state 1, enters in cornea 3 from corneal incision 3-1 and is deformed into expansion state 1a
Become square, iris can be expanded.It cannot be used for the master that must be done in operation relative to conventional iris extension fixture
Corneal incision is wanted, and is needed for being additionally 4 corneal incision 3-1b during surgery, corneal incision wound is smaller.
It further include for being sleeved on the moving casing 3 being in outside the side the n shape closed loop of contraction state 1 in the present embodiment.
When the shape closed loop contraction state 1 of the side n be set with moving casing 3 enter in cornea from corneal incision 3-1, when the side n shape closed loop completely into
Afterwards, moving casing 3 is extracted out.
In the present embodiment, the side the n shape closed loop is the equal quadrangle closed loop of each edge.Equilateral quadrangle closed loop is convenient for behaviour
Make, number of edges is not allowed easy to operate too much.
In the present embodiment, the adjacent both sides of the quadrangle closed loop are hinged by articulated shaft 1-1 and hinge hole 1-5, hingedly
It is provided with mutually matched axial raised line between axis 1-1 and hinge hole 1-5 and groove, hinge hole 1-5 are arranged on trunnion 1-4.
Cooperated by raised line and groove so that quadrangle form has certain stability, when being particularly in expansion state 1a, four sides
Shape closed loop by the reaction force of iris have the tendency that deforming back to contraction state and may, raised line and groove prevent nature from becoming
Shape, so that quadrangle closed loop can just deform in the case where power drive only outside manual operation.
In the present embodiment, the articulated shaft and hinge hole are made of polyacrylate material.It can certainly be used
Allogene is compatible and sterilizable material, flexible and flexible using polyacrylate, can reduce articulated shaft relative to hinged
The resistance of raised line and groove when hole rotates, operates more convenient.
It is the planar shaped convenient for being avoided mutually when contraction state on the inside of each edge of the quadrangle closed loop in the present embodiment
Shape 1-2.Overall width when contraction state is smaller, can reduce the diameter of corneal incision 3-1, smaller to the injury of cornea.
In the present embodiment, cross section is convenient for fixing the concave surface of iris edge inwardly on the outside of each edge of the quadrangle closed loop
" C " type.
In the present embodiment, it is provided on the outside of each edge of the quadrangle closed loop convenient for the drag hook of drag hook operational transformation state
Hole 1-3.Drag hook hole 1-3 can be through-hole, as long as iris hooks are inserted into being operated.
In the present embodiment, the outer middle side part of each edge of the quadrangle closed loop is arranged in the drag hook hole 1-3.Setting exists
Outer middle side part contraction state width does not increase, if the hinged place of end is arranged in, will lead to the increase of contraction state width, leads
The cornea major incisions diameter needed is caused to increase.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
