Description

Uprawniony z patentu: Aesculap-Werke A^l^gesellschaft, Vormals Jet- ler-und Scheerer, 1?§£tlingen (Republika Federal¬ na Niemiec) Kleszcze chirurgiczne Przedmiotem wynalazku sa kleszcze chirurgicz¬ ne, zwlaszcza do celów medycznych, z dwoma ra¬ mionami, które sa polaczone ze soba na osi ob¬ rotowo.Zname sa kleszcze tego rodzaju, w których do polaczenia obu ramion stosowana jest przetyczka w formie niftu lub sruby, sluzaca jednoczesnie jako os obrotowa. Przetyczka znajduje sie w po¬ krywajacych sie osiowo otworach scianek wpustu i czesci przelykowej i polaczona jest, z doklad¬ nym pasowaniem, ze szlifowanym ramieniem kle¬ szczy. To uksztaltowanie kleszczy z zamkiem prze- tykowym ma, w szczególnosci w kleszczach sluza¬ cych jako instrument chirurgiczny, znaczne wady.Kleszcze chirurgiczne takie jak na przyklad za¬ ciski tetnicze, szczypce do usuwania polipów, szczypczyki, kleszcze do kamieni nerkowych, kle¬ szcze zoladkowe, kleszcze jelitowe korncangi, pin¬ cety do tamponów, pincety do przemywania, za¬ ciski do tkanin, kleszcze do klamer, klemy bron- choskopowe, kleszcze anastezyjne, kleszcze zweza¬ jace, kleszczyki Halsteda, kleszcze preparacy.jne, kleszcze do podwiazywania naczyn i podobne kle¬ szcze chwytne, szczypce dentystyczne, szczypce techniczno-denlystyczne, imadla, kleszcze przebi- jakowe, kleszcze do odlamków kosci, nalezy pod¬ dawac w czasie wytwarzania hartowaniu, w za¬ leznosci od rodzaju materialów i musza oprócz tego sprostac zwiekszonym wymaganiom z powodu 10 15 20 25 30 wygotowywania, sterylizacji na goraco i parowej po kazdym ich stosowaniu.Ta obróbka cieplna materialów moze prowa¬ dzic do tego, ze powstaja na kleszczach, w szcze¬ gólnosci na sciankach wpustu wychodzace od ot¬ woru lub w ich kierunku, rysy w materiale, które powoduja nieprzydatnosc kleszczy. Jezeli jako przetyczka polaczeniowa przewidziany jest nit, to przy nitowaniu moga wystapic w tych samych miejscach napiecia, które prowadza pózniej do powstawania rys.Wytwarzanie znanych kleszczy z zamkiem prze¬ lykowym jest równiez stosunkowo skomplikowa¬ ne, poniewaz przetyczka polaczeniowa uksztalto¬ wana jako nit lub sruba musi byc zanitowana wzglednie wkrecona w pokrywajace sie ze soba otwory w sciankach wpustu i w czesci przelyko¬ wej. Celem wynalazku jest skonstruowanie kle¬ szczy do celów medycznych, w których ramiona kleszczy polaczone sa ze soba w znany sposób za pomoca zamku przelykowego. Pod slowem zamek przetykowy rozumie sie polaczenie pomiedzy obu ramionami kleszczy, przy którym w czasie mon¬ tazu kleszczy jedno ich ramie przetykane jest przez drugie za pomoca rozszerzonego polaczenia na wpust.Cel ten zostal osiagniety w ten sposób, ze za¬ miast znanej przetyczki polaczeniowej co najmniej na jednej wewnetrznej powierzchni scianki wpu- 83 36683 366 * 3 stu jest wystep jako czesc laczaca, która stanowi ze scianka wpustu jedna calosc i wchodzi w wy¬ branie lozyskowe czesci przetykowej. Osiaga sie przez to wzmocnienie scianek wpustu przez za¬ stosowanie wystepu, a nie oslabienie ich z powodu otworów. Równiez unika sie niebezpieczenstwa korozji kontaktowej i z powodu tworzenia sie rys na sciankach wpustu i na czesci laczacej, ponie¬ waz stanowi ona jedna calosc ze scianka wpustu.Podczas gdy w znanych kleszczach celem uni¬ kniecia rys na sciankach wpustu nalezy wybierac mozliwie mala srednice otworów i tym samym mala srednice przetyczki polaczeniowej, to zgod¬ nie z wynalazkiem srednica ta moze byc dowolnie duza. Mozna równiez zamiast przetyczki polacze¬ niowej stc^^anej w znanych szczypcach zasto¬ sowac wystep, -odpowiadajacy swoja funkcja wy¬ stepowi czopowemu, w postaci zebra pierscienio¬ wego, które wchodzi w uksztaltowane jako rowek pierscieniowy wybranie lozyskowe. Dzieki temu mozna utworzyc przy minimalnym oslabieniu czesci przetykowej przez rowek pierscieniowy, bardzo mocne polaczenie pomiedzy obu ramiona¬ mi kleszczy.Przedmiot wynalazku przestawiony zostal w przy¬ kladzie wykonania na rysunku, na którym fig. 1 przedstawia kleszcze w widoku z góry, fig. 2 — w powiekszenia ich przekrój po linii II-II z fig 1, fig. 3 — element nieobrobiony ramienia kleszczy z fig. 1 i 2 w wiidclku bocznym czolowym, fig. 4—5 — element nieobrobiony zwpustami po ich wykonaniu wzglednie po rozszerzeniu wpustów, w powiekszo¬ nym widoku czastkowym odpowiadajacym fig. 3., fig. 6 — element nieobrobiony ramienia kleszczy bez wpustów po jego wytworzeniu w widoku cza¬ stkowym odpowiadajacym fig. 3, fig. 7 — inny przyklad wykonania kleszczy w widoku odpowla¬ dajacym fig. 2.. Kleszcze chirurgiczne przedstawione na fig. 1 i 2 maja dwa ramiclia 1, 2 polaczone obrotowo ze soba za pomoca zamka przetykowego 4 na osi 3. Kazde z ramion kleszczy ma szczeke 5 i dzwig¬ nie chwytna 6. Zamek przetykowy 4 znajduje sie; pomiedzy szczekami 5 z jednej strony i dzwignia¬ mi chwytnymi 6 z drugiej strony i utworzony jest w ten sposób, ze w jednym ramieniu 1 kle¬ szczy pomiedzy jego szczeka 5 i dzwignia chwyt¬ na 6 wykonany jest wpust 7 polozony skosnie do osi 3, przez który przechodzi czesc przetykowa 8 utworzona na drugim ramieniu 2 kleszczy : spla¬ szczona. Czesc przetykowa ma otwór koncentry¬ czny z osia 3 sluzacy jako wybranie lozyskowe, którego oba zewnetrzne obrzeza rozszerzone sa na zewnatrz rozbieznie. Jako czesc laczaca po¬ miedzy obu ramionami 1 i 2 wykonane sa kon¬ centryczne czopowe wystepy 11 na obu zwróco¬ nych do siebie wewnetrznych powierzchniach scianek wpustu 7, które wchodza w otwór 9 cze¬ sci przetykowej 8 i tworza os obrotowa 3.Na fig. 7 przedstawiono inny przyklad klesz¬ czy. Czesci tych kleszczy odpowiadajace funkcyj¬ nie poprzedniemu przykladowi wykonania ozna¬ czone symbolami cyfrowymi powiekszonymi o 100, aby je mozna bylo porównac z przykladem 5 wykonania wedlug fig. 1 i 2.Kleszcze wedlug fig. 7 róznia sie od poprzed¬ nich tym, ze jako wybranie lozyskowe zamiast otworu 9 maja na obu stronach czesci przetyko¬ wej 108 po jednym rowku pierscieniowym 169, 10 w który wchodzi jako wystep polaczeniowy ze¬ berko pierscieniowe 111. Zaleta tego przykladu wykonania jest to, ze czesc przetykowa nie jest oslabiona przez otwór przelotowy 9 oraz ze scianki wpu&tu zostaja wzmocnione dodatkowo przez zeberko pierscieniowe 111. Ponadto po¬ wstaja przy tym dwie koncentryczne powierzchnie prowadzace dla zewnetrznej i wewnetrznej po¬ wierzchni pierscieniowej zeberka 111.Niezaleznie od powyzszych przykladów wynala¬ zek mozna zastosowac do kleszczy i instrumen¬ tów w postaci kleszczy lub narzedzi dowolnego rodzaju na przyklad równiez przy wytwarzaniu no¬ zyczek lub podobnych w których dwa ramiona polaczone sa na jednej osi obrotowo za pomoca zamka przetykowego. 15 20 30 PLThe holder of the patent: Aesculap-Werke A ^ l ^ gesellschaft, Vormals Jetler- und Scheerer, 1 ^ § ^ tlingen (Federal Republic of Germany) Surgical forceps The invention relates to surgical forceps, especially for medical purposes, with two arms that are connected to each other in a pivotal axis. ZNAME are pliers of the kind in which a pin in the form of a nift or a screw is used to connect the two arms, simultaneously serving as a pivot axis. The cotter is located in the axially overlapping holes in the walls of the groove and the escutcheon and is connected with a perfect fit to the ground glue arm. This design of the forceps with a throat lock has significant drawbacks, particularly in forceps that serve as a surgical instrument. Surgical forceps such as, for example, arterial clamps, polyp removal forceps, forceps, kidney stone forceps, and sticks. gastric, intestinal forceps, corncobs, tampon forceps, rinsing forceps, cloth clamps, clamp forceps, bronchoscopic clamps, anasthetic forceps, narrowing forceps, Halsted forceps, preparation forceps, ligation forceps Vessels and similar grasping jaws, dental pliers, technical-denlist pliers, vices, piercing forceps, bone fragments forceps, must be tempered during manufacture, depending on the type of materials, and must also cope with the increased requirements due to boiling, hot sterilization and steam sterilization after each use. This heat treatment of the materials can lead to this about the fact that they are formed on the ticks, especially on the walls of the inlet protruding from or towards the opening, scratches in the material that make the ticks unsuitable. If a rivet is provided as a connecting pin, then during riveting, they can occur at the same stress points which later lead to crack formation. The production of known forceps with an eyelet lock is also relatively complicated, since the connecting pin is shaped as a rivet or the bolt must be riveted or threaded into coinciding holes in the walls of the groove and in the esophagus. The object of the invention is to construct clas for medical purposes in which the arms of the forceps are connected to each other in a known manner by means of an esophagus lock. A thru-lock is understood as a connection between the two arms of the ticks, whereby one arm is threaded through the other during the installation of the ticks by means of an extended groove joint. This aim was achieved in such a way that instead of the well-known connecting pin, On at least one inner surface of the groove wall there is a projection as a connecting part, which is one whole with the groove wall and enters the bearing recess of the throat part. This achieves a reinforcement of the groove walls by the provision of a projection, rather than weakening them by the holes. The risk of contact corrosion is also avoided and due to the formation of scratches on the groove walls and on the connecting part, as it forms one whole with the groove wall, while in known pliers, in order to avoid cracks on the groove walls, the diameter of the holes should be chosen as small as possible and thus the small diameter of the connecting pin, the diameter can be as large as desired according to the invention. It is also possible to use a protrusion, corresponding to its function, in the trunnion, in the form of an annular rib, which fits into the bearing cavity shaped as an annular groove, instead of a connecting pin. As a result, with minimal weakening of the throat part by the annular groove, a very strong connection between the two tongs of the forceps can be created. The subject of the invention is illustrated by an example of embodiment in the drawing, in which Fig. 1 shows the forceps in a top view, Fig. 2. - in enlargements, cross-section on the line II-II from fig. 1, fig. 3 - blank element of the forceps arm from fig. 1 and 2 in the side front view, fig. 4-5 - element not machined with grooves after their production or after widening the grooves, in an enlarged partial view corresponding to Figs. 3, Fig. 6 - a blank element of the tongs arm without grooves after its production in a partial view corresponding to Figs. 3, Fig. 7 - another embodiment of the ticks in a view corresponding to Fig. 2. The surgical forceps shown in Figs. 1 and 2 have two arms 1, 2 pivotally connected to each other by means of a thrust lock 4 on axis 3. Each of the forceps arms has a jaw 5 and a gripping lever 6. the plug 4 is located; between the jaws 5 on the one side and the gripping levers 6 on the other side, and is formed in such a way that in one arm 1, between its jaws 5 and the grip lever 6, there is a groove 7 inclined to the axis 3, through which the throat part 8 formed on the other arm 2 of the ticks passes: flattened. The thrust part has a concentric bore with axle 3 serving as a bearing recess, the two outer periphery of which are outwardly flared apart. As a connecting part between the two limbs 1 and 2, concentric spigot projections 11 are provided on the two inner faces of the groove 7 facing each other, which engage in the opening 9 of the throat part 8 and form the rotational axis 3. 7 shows another example of a forceps. The parts of these ticks functionally corresponding to the previous embodiment are marked with numerical symbols increased by 100 so that they can be compared with the embodiment 5 according to Figs. 1 and 2. The ticks according to Fig. 7 differ from the previous ones in that the quality of a bearing recess instead of a hole on both sides of the throat part 108 on both sides of the annular groove 169, into which the ring tooth 111 fits as a connecting projection. The advantage of this embodiment is that the throat part is not weakened by the through hole 9 and that the inlet walls are additionally reinforced by the annular rib 111. In addition, two concentric guide surfaces are created for the outer and inner annular surfaces of the rib 111. Regardless of the above examples, the invention can be applied to forceps and instruments in the form of forceps or tools of any kind, for example also in the manufacture of scissors or the like in which two arms are pivotally connected on one axis by means of a bolt lock. 15 20 30 PL
