Abstract
The utility model discloses one kind to be used for ophthalmic lens subluxation surgical pocket syringe；Including head, body portion, tail portion；The 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 bends downward rear and reversed bending, forms one section of reflexed section；The head is the intrusion pipe being arc-shaped, and the whole opposite tail portion of intrusion pipe is diagonally downward.Due to being entered in lens capsule bag by cut-out of limbus corneae for the utility model, cambered design enables the syringe to coincide with lens capsule bag ambitus, maintain the stabilization of cyst membrane in art, fine-meshed in camber circle, it is easy to separate lens capsule bag ambitus cortex water, facilitates and absorb remaining cortex of lens in art, body portion is fixed by corneal incision, it maintains pouch in a plane, has the advantages that operation is simple and reliable.
Description
Technical field
The utility model relates to a kind of medical instruments, are used for ophthalmic lens subluxation surgical pocket more particularly to one kind
Syringe.
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
Operation is simple and reliable performs the operation capsule for ophthalmic lens subluxation the purpose of this utility model is to provide a kind of
Bag syringe.
To achieve the above object, the technical solution of the utility model is:
The utility model is a kind of for ophthalmic lens subluxation surgical pocket syringe；Including head, body portion, tail
Portion；The head, body portion, tail portion are sequentially connected, and head and body portion are all hollow tube made of metal material；The tail portion
For infusion apparatus bayonet, it 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, body portion
Outer end bends downward rear and reversed bending, forms one section of reflexed section；The head is the intrusion pipe being arc-shaped, and intrusion pipe is whole
Body is diagonally downward with respect to tail portion.
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 the head of the utility model is hollow arc intrusion pipe, cambered design, end circle
Blunt closed, 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 card
Mouthful, external infusion apparatus.The pouch syringe is entered in lens capsule bag by 1mm cut-out of limbus corneae, and cambered design makes the perfusion
Device can coincide with lens capsule bag ambitus, maintain the stabilization of cyst membrane in art, and fine-meshed in camber circle is easy to make lens capsule
Bag ambitus cortex water separation facilitates and absorbs remaining cortex of lens in art, and pouch perfusion body portion is fixed by corneal incision,
It maintains pouch in a plane, achievees the purpose that pouch position is constant, have the advantages that operation is simple and reliable.
The utility model is further described in the following with reference to the drawings and specific embodiments.
Detailed description of the invention
Fig. 1 is the top view of the utility model；
Fig. 2 is the front view of the utility model；
Fig. 3 is the usage state diagram of the utility model.
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model 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.
One concrete structure design of the utility model 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 one every 30 °
Diameter is the thin through-hole of 0.2mm, and entire arc intrusion pipe opens up multiple thin through-holes, and it is 7 that arc intrusion pipe, which constitutes big ring diameter D,
~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.
The application method of the utility model:
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 syringe 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
Lens capsule bag ambitus cortex water is separated, facilitates and absorbs remaining cortex of lens in art, pouch perfusion body portion passes through angle
Film notch is fixed, and is maintained pouch in a plane, is achieved the purpose that pouch position is constant.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this
Range should still belong to this reality that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description
In the range of being covered with new patent.
