ί: Injection tweezers under constant tension for

Extraction of the ocular cataract

The invention relates to forceps used for capsule lens extraction of the staring eyes "determined 1st, Yerschie- * The types of forceps used for this operation are known; they differ from each other in terms of the we «· s borrowed by the end of their thighs, γ / elche ab— are flat and blunt * They are all designed so that they can easily grasp the capsule with minimal kissing. Allow driving «. Certain forceps have a double End curvature. " Anfee have an egg on the inner surface of the end of a leg * Sometimes there is also a Stop provided to limit the pressure of which If the risk of injury to the capsule is exceeded, » would interpret ». . -

Compartment an important feature of the invention comprises a pair of tweezers, which is under constant pressure due to the crosswise arrangement of the jaws, fixed with one jaw of the pin * zette-related means for injecting liquid into the anterior chamber of the eye, These means can consist of a thread-like line exist, which is provided in an arm

which opens at the end of a jaw * The line can also, be welded along one leg * It is also possible to attach the line so that it can be removed can be easily removed and reattached «, In the the latter lall can be the end of a jaw, preferably the left cheek, advantageously have a slight thickening with a hole and a sudden expansion to accommodate and hold the end of the line. In each lalle has the tweezers or the wire on the other End an end piece to open a flexible and long duct * - » increase i this "consists of plastic material, such as" B " a synthetic resin, through it the various are in the lukewarm ~ fluids used during the operation introduced *

Further advantages and details of the invention result from the following description of exemplary embodiments using the drawing j in this show: -

Hg * 2 a side view of the same forceps,. "

Pig * 4 a single answer ± .c ± fc of the end part of such Cheek »-

The tweezers usually have two legs in the lorm of strips 1 and 2 on which are stuck at the bottom. are connected to each other and form a leather * The

the legs of the tweezers merge into two at the end Jaws 3 and 4 arranged crosswise so that these two jaws are normally on top of each other in the idle state * Therefore, a slight pressure must be exerted on the thighs in order to open the forceps and to close the To prevent baking. The two jaws are more advantageous Curved way as shown at 5 *

line thread-like line 6 can be _{welded at 7 aa end of a jaw 8 S,} preferably on the left one * It is further welded via an end piece 8 in the lower part of the same jaw aage «. Due to simple friction, a soft, elastic tube can sit on this end piece, through which the various liquids can be introduced. Purpose, the end of a jaw has a somewhat thicker area 9, which is pierced at 15 and is provided with an abrupt extension 14 into which the end of the thread-like line 10 is inserted. A bracket 12 is welded to the lower end of the same jaw and fastened, on which the end piece 11 is arranged "A means for clamping and fastening, the line can consist of a screw 13 or any other suitable element" The tweezers are used as follows: ':

The surgeon grabs the crystal by its lower part .. "" "" End as he did with every other known pair of tweezers .. '. would make so that the pierced end of the forceps located under the iris * Give slight movements

the ability to determine the grasping / on it In this pail, a substance that is able to destroy the hanging «" straps of the lens becomes that A-Ghymo-Trypsin, and then injected a serum, to "eliminate the liquid introduced." The ligament "freed" lens then floats in the anterior chamber, continuing to do so held by the capsule handle of the tweezers, they will then be in accordance with the classic Procedure pulled out after a twist *, So the extraction of the ocular starch is due to the addition the "fluid that destroys the ligaments" is very relieved. The various manipulations are of very short duration they are only made possible by the! tweezers-under constant tension, which prevents finger fatigue »

The above statements are of course only a schematic description of an operation ^ of course however, other injections may be made to the blood or other injections if necessary Eliminate substances such as acecoline Moment with the tweezers held in place, "
