Description
Technical field
The present invention relates to a kind of medical instruments, are perfused more particularly to one kind for ophthalmic lens subluxation surgical pocket
Device.
Background technique
In ophthalmic lens operation, the stability of crystalline lens itself Lens capsular for forward and backward atrial pressure power maintenance especially
It is important.Cyst membrane it is unstable, be easy to appear perfusion liquid and enter back room, make back room pressure rise, Prevention and treatment enters anterior chamber, draws
Anterior chamber's vitreous hernia is played, intraocular pressure is high, and intraocular lens are difficult to be satisfactorily implanted in pouch.It is tough due to hanging for subluxation of lens
The relaxation or fracture of band, pouch ambitus and rear capsule are unstable, and perfusion liquid is easy to appear in art and enters back room, back room pressure liter
Height, vitreum overflow into anterior chamber, Lens capsular shrinkage occur, displacement, even rupture, operating difficulty is caused to increase.
Currently, clinically reach stable pouch often with capsular retractors or the fixed anterior lens capsule of iris hooks.But pouch
Capsule partial region before pull hook or iris hooks are only fixed, belongs to point-to-point support and fixes, equal for pouch ambitus and rear capsule
In vain, in zonular breaking or larger loose zone, Lens capsular is easier to pour in anterior chamber, causes anterior chamber unstable.
Summary of the invention
The purpose of the present invention is to provide a kind of ophthalmic lens subluxation surgical pockets that is used for that operation is simple and reliable to fill
Infuse device.
To achieve the above object, the technical solution of the invention is as follows:
The present invention is a kind of for ophthalmic lens subluxation surgical pocket syringe；Including head, body portion, tail portion；Described
Head, body portion, tail portion are sequentially connected, and head and body portion are all hollow tube made of metal material；The tail portion is infusion apparatus
Bayonet is connect with body portion；The body portion inner end is connect with tail portion, and the outer end in body portion is connect with head, and the outer end in body portion is downward
Reversed bending again, forms one section of reflexed section after bending；The head is the intrusion pipe being arc-shaped, the whole opposite tail of intrusion pipe
Portion is diagonally downward.
The head is the intrusion pipe in 120~270 ° of arcs.
Offer multiple thin through-holes being connected to hollow lumen on the tube wall on the head, multiple thin through-hole is equidistant,
Interval setting.
After adopting the above scheme, since head of the invention is hollow arc intrusion pipe, cambered design, end round blunt is close
It closes, the multiple thin through-holes of arc-like inner band band, perfusion liquid is easy to flow out from hole, and body portion is connection reflexed pipe, and tail end is standard bayonet, outside
Connect infusion apparatus.The pouch syringe is entered in lens capsule bag by 1mm cut-out of limbus corneae, and cambered design enables the syringe
It coincide with lens capsule bag ambitus, maintains the stabilization of cyst membrane in art, fine-meshed in camber circle is easy to make lens capsule bag equator
Cortex water separation in portion's facilitates and absorbs remaining cortex of lens in art, and pouch perfusion body portion is fixed by corneal incision, maintains capsule
Bag achievees the purpose that pouch position is constant, has the advantages that operation is simple and reliable in a plane.
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.
Detailed description of the invention
Fig. 1 is top view of the invention；
Fig. 2 is front view of the invention；
Fig. 3 is usage state diagram of the invention.
Specific embodiment
As shown in Figure 1 and Figure 2, the present invention is a kind of for ophthalmic lens subluxation surgical pocket syringe；Including head
1, body portion 2, tail portion 3.
The head 1, body portion 2, tail portion 3 are sequentially connected, and head 1 and body portion 2 are all hollow tube made of metal material；
The tail portion 3 is infusion apparatus bayonet, is connect with body portion 2；2 inner end of body portion is connect with tail portion 3, the outer end in body portion 2 with
Head 1 connects, and the outer end in body portion 2 bends downward rear and reversed bending, forms one section of reflexed section, which is in " door " font.
The head 1 is in 120~270 ° of arc-shaped intrusion pipes, and intrusion pipe is tilted towards for whole opposite tail portion 3
Under.Offer multiple thin through-holes 11 being connected to hollow lumen on the tube wall on the head 1, multiple thin through-hole 11 is equidistant,
Interval setting.
A concrete structure design of the invention is as follows:
As shown in Figure 1-Figure 3, the pipe outside diameter 0.5mm on the head 1, bore 0.3mm, edge have a diameter every 30 °
For the thin through-hole of 0.2mm, entire arc intrusion pipe opens up multiple thin through-holes, arc intrusion pipe constitute big ring diameter D be 7~
10mm。
The body portion 2 is a connection reflexed pipe, and pipe outside diameter 0.5mm, bore 0.3mm, length L1 is 10mm, invagination
Height H is 1.5mm, and reflexed extending length L2 is 2mm, is connected with head 1.
The infusion apparatus bayonet tube overall diameter 6.8mm of the tail portion 3, pipe interior diameter 4mm, long 17mm.
Application method of the invention:
Pouch syringe is entered in lens capsule bag 10 by 1mm cut-out of limbus corneae, and the design of 1 arc intrusion pipe of head makes the filling
Infusing device can coincide with 10 ambitus of lens capsule bag, maintain the stabilization of cyst membrane in art, and the thin through-hole 11 on head 1 is easy to make crystalline substance
The separation of shape somatocyst bag ambitus cortex water facilitates and absorbs remaining cortex of lens in art, and pouch perfusion body portion is cut by cornea
Mouth is fixed, maintains pouch in a plane, achievees the purpose that pouch position is constant.
The above is only the preferred embodiment of the present invention, therefore cannot be limited the scope of implementation of the present invention with this, i.e., according to
Equivalent changes and modifications made by scope of the present invention patent and description should still belong to the model that the invention patent covers
In enclosing.
