Abstract
The utility model discloses a lenticular discission needle, and is mainly used for the lenticular anterior capsule incision in an eye cataract phacoemulsification extraction surgery. The lenticular discission needle comprises a handle, a needle bed, a needle body and a needle head which are connected into a whole in sequence, and is characterized in that the whole needle is made of a high-temperature and high-pressure resistant metal material, the handle takes the shape of a round column, the corresponding arc-shaped sink on the handle is a needle holding mark. The needle bed takes the shape of a taper. The needle body takes the shape of a line, the part of the needle body two-thirds distance from the needle bed takes the shape of a bend of 130 degrees to 140 degrees, and the far end of the bend takes the shape of an arc. The needle head takes the shape of a double-blade inverted triangle, a knife edge is sharp, and a knife head and a knife body takes the angle of 90 degrees. The utility model is the special instrument for cutting the anterior capsule prior to the cataract phacoemulsification, has simple structure, low cost, easy manufacture, safe and reliable operation, and can be used repeatedly after disinfection.
Description
Technical field:
This utility model relates to a kind of ophthalmologic operation medical apparatus and instruments.Be a kind of ophthalmology scalpel, be exclusively used in cataract ultrasonic emulsification enucleation cutting anterior lens capsule film, create good conditions for lens capsule bag is implanted into the artificial intraocular lenses.
Background technology:
At present, in the cataract ultrasonic emulsification excising operation, anterior lens capsule film incision process has the capsule method of cutting and tears the capsule method.Cut the capsule method, promptly cut broken dozens of point hole with discission needle in anterior lens capsule film upper edge annular, the side edge of using the discission needle head then removes the annular anterior capsule of scratching with Tweezers for eye surgery then at standardized toroid between points.Tear the capsule method, carry out curvilinear capsulorhexis with the cyst membrane tweezers exactly.Present discission needle used in cataract procedure, great majority are that interim quick test point head with the 1ml disposable syringe is made in operation,, and operation all needs to make at every turn, and more loaded down with trivial details, time-consuming.Existing crystalline lens cutting the hydatoncus and blade scalpel manufacturing complexity, and be difficult to operation in the limited space of anterior chamber, viscoelastic agent overflows and makes obliteratio camerae anterior in the as easy as rolling off a log anterior chamber of causing, and the damage corneal endothelial layer influences surgical effect.
The utility model content:
The deficiency that used apparatus exists when cutting capsule in order to solve the cataract ultrasonic emulsification crystalline lens that exists in the above-mentioned background technology, this utility model just provides a kind of crystalline lens discission needle of special use.Make simply, easy to operate, reusable, and shorten operating time, safe and reliable.
The technical solution of the utility model is to realize in the following manner:
A kind of crystalline lens discission needle comprises handle, needle stand, needle body and syringe needle etc.It is characterized in that: integral body is made for the high temperature high voltage resistant metal material, it is cylindric that handle is, corresponding arc-shaped recess is to hold the pin mark note on the handle, handle one end cone is a needle stand, it is linear that needle body is, be 130 °～140 ° bendings at distance needle stand 2/3 place, the bending far-end is curved, and the anterior convexity of radian and crystalline lens is close.Syringe needle is the twolip del, and blade is sharp, and cutter head and cutter hub are 90 °.
Good effect of the present utility model:
1, this apparatus is whole makes for the high temperature high voltage resistant metal material, can repeat autoclave sterilization and use.
2, this apparatus structure is simple, and is easy to make, with low cost.
3, this apparatus is that crystalline lens cuts the capsule special equipment, promptly shortens operating time, alleviates the patient suffering.
4, the pin mark note is held at handle one end distance needle stand 1/3 place, and favourable patient confirms syringe needle blade direction and quiet run.
5, this apparatus needle body one end distance needle stand 2/3 place is 130 °～140 ° bendings, and the bending far-end is curved, and the anterior convexity of radian and crystalline lens matches, and it is dark excessively both to have avoided entering the anterior chamber, and handled easily is safe and reliable again.

Fig. 4 is that A of the present utility model is to view
The specific embodiment:
Below in conjunction with accompanying drawing utility model is described further: at Fig. 1,2,3,4 concrete structure of crystalline lens discission needle as can be seen: a kind of crystalline lens discission needle comprises handle (1), needle stand (3), needle body (4) and syringe needle (5).It is characterized in that: handle is cylindric, and pin mark note (2) is held at handle one end distance needle stand 1/3 place, and needle stand (3) is coniform, and needle body (4) is wire, and needle body is 130 °～140 ° bendings apart from needle stand 2/3 place, and the bending far-end is curved.Syringe needle (5) is the twolip del, and blade is sharp, and cutter head and cutter hub are 90 °.
In the cataract ultrasonic emulsification excising operation, after the incision anterior chamber injects viscoelastic agent anterior chamber recovery, crystalline lens discission needle level is entered the anterior chamber, when syringe needle arrives before the crystalline lens with it vertically downward, annular is cut broken dozens of point hole in anterior lens capsule film upper edge, the side edge of using the discission needle head then according to the size of checking nucleus lentis before the art, withdraws from the anterior chamber at standardized toroid between points after cutting annular incision that an about diameter is 5～6mm on the anterior lens capsule film.Tear capsule with Tweezers for eye surgery then.Both avoided cyst membrane to tear to the ambitus that damage apparatus suspensorius lentis portion cyst membrane causes cyst membrane to be torn making the intraocular lens implant difficulty and intraocular lens's off normal complication takes place, easy to operate again, safe and reliable, can also reuse.
Claims (3)
1. crystalline lens discission needle, comprise handle (1), needle stand (3), needle body (4) and syringe needle (5), it is characterized in that: handle is cylindric, symmetric arc-shaped recess is to hold pin mark note (2) on the handle, and handle one end cone is needle stand (3), and needle body (4) is linear, be 130 °～140 ° bendings at distance needle stand 2/3 place, the bending far-end is curved, and syringe needle (5) is the twolip del, and cutter head and cutter hub are 90 °.
