Fixation forceps for inserting Y / root canal instruments

The subject of the invention is a special brush for insertion of root canal instruments such as serv canal wideners, cat-tail files » Root canal rasps and bearings, root stitches, Bervnadeln, Vvurselfüllnadeln as well as paper and celluloid points.

It is common practice that used for root canal treatments to grasp small spool channel instruments by hand. at the treatment of the back teeth and with a relatively small mouth opening is the introduction of these instruments into the Wursel canal but often difficult and confusing and you have to fumble around for a long time before you succeed in finding the right one Introduce the instrument into the Hiursel Canal.

For the sake of clarity, the small instruments like tweezers. A normal dental Tweezers can be used for this, but unsuitable because the small instrument evades very easily, can jump out of the tweezers and fall into the mouth * without overdoing it, in such cases there is all too easy a risk of swallowing. An anatomical forceps is for this purpose Already more suitable, but not yet so handy for fixing small instruments that you can work with them calmly and safely can. Here, too, the WurEelkanalinstrument deviates slightly out and yet is not as fixed as it should be.

The purpose of the new tweezers is to remove the parts described above to eliminate. The way they work is as follows: The tips (working parts) encompass semicircular grooves that are cross-grooved Killer the shaft of the required Y / root canal instrument from on all sides, not just at two support points as with ordinary tweezers. The tension of the compressed Tweezer branches and their tips causes an immovable Holding the jammed instrument. A springy bracket

PA516672.1a9.ifi J EBRU DER MARTIN -2- (fixing forceps for root canal instruments) with hooks, mounted inside the forceps »automatically locks into a window when the two branches of the forceps are pressed together and with the tension of the forceps tips upright as long as desired. This frees the hands from exerting any pressure in the mouth while working, which is what makes sensitive and relaxed work possible in the first place. After the root canal instrument, clamped in the forceps, has been inserted into the root canal, all that is required is pressure on the hook protruding through the window in the direction of the forceps tip to release the lock and release the clamped root canal instrument. By arranging the grooves in different directions, three different positions of the root canal instruments are possible (see sketch). When treating the root canals, which also run in different directions, this is of practical importance insofar as the forceps do not have to be extremely rotated during use. The new tweezers are shown in the drawing, for example, and are described in more detail below using this.The tweezers consist of two parts, the hand side a with the two handle branches and the working side b, represented by the tweezer tips with grooves £.
