Description

Vynález sa týká kanyly s bočným otvorom na odběr vzorky tkaniva tuku a svalu zo živého zvieraťa v množstve potrebnom na jeho fyzikálně a chemické vyšetrenie.The invention relates to a cannula with a lateral opening for collecting a sample of fat and muscle tissue from a living animal in an amount necessary for its physical and chemical examination.

Doterajšie běžné metody biopsie nesplňajú požiadavky, pretože vyžadujú fixáciu zvieraťa, připadne celková alebo lokálnu anestéziu, čo značné zvyšuje ich náklad a znižuje rýchlosť prevedenia.Current conventional biopsy methods do not meet the requirements because they require fixation of the animal, or general or local anesthesia, which greatly increases their cost and reduces the rate of transposition.

Strielací přístroj, použitý v NDR vyžaduje vhodná kanylu, ktorá umožňuje vlastný odběr.The firing device used in the GDR requires a suitable cannula to allow self-collection.

Doterajšie spósoby riešenia kanýl použitých v NDR a CSSR podlá АО 190 282 umožňovali sice cdber dostatočného množstva tuku a svalového tkaniva potřebného na jeho fyzikálně a chemické vyšetrenie, vyznačovali sa róznym stupňom náročnosti riešenia funkčnej časti. Tieto kanyly pozostávajá z nosnej časti s odvzdušňovacími otvormi, alebo medzičlánku, ktorým sá rozoberateTne upevněné na strieTacie zariadenie. Ďalej tieto kanyly sá vytvořené z nerezovej rárky, ktorá má v prednej časti skosená predná hranu a má vo vnútri rárky záchytné zariadenie. Tieto kanyly po odbere vzorky vyžadovali vždy odkrátenie kanyly zo strieracieho prístroja a vytlačenie odobratej vzorky. Odskrutkovávanie kanyly zo strieTacieho prístroja po odbere vzorky predlžovalo čas manipulácie a vytláčanie vzorky z kanyly mohlo viesť к porušeniu tukového a svalového tkaniva.The current methods of solving cannulas used in the GDR and CSSR according to АО 190 282 allowed the cdber sufficient fat and muscle tissue needed for its physical and chemical examination, they were characterized by different degrees of difficulty in solving the functional part. These cannulae consist of a carrier part with venting holes, or an intermediate piece, by means of which they can be detachably fastened to the spray device. Furthermore, these cannulae are formed of a stainless steel tube having a bevelled front edge at the front and having a retaining device inside the tube. These cannulae, after sampling, always required to cut the cannula from the wiper and to dispense the collected sample. Unscrewing the cannula from the sprayer after sample collection has prolonged handling time and displacement of the sample from the cannula could result in disruption of adipose and muscle tissue.

Uvedené nedostatky odstraňuje kanyla s bočným otvorom na odběr vzorky tkaniva, tuku a svalu zo živého zvieraťa, ktorá je priamo nosnou častou, alebo medzičlánkom rozoberatelne upevněná na striefacie zariadenie a je vytvořená z nerezovej rárky, ktorá má v nosnej časti odvzdušňovacie otvory a upevňovacie zariadenie, pričom predná časť nerezovej rárky má skosená predná hranu. Podstata kanyly podlá vynálezu je v tom, že v nerezovej rurke je od jej středu směrem к jej prednej časti vytvarovaný pozdížny otvor dlžky 1/4 až 2/5 celkovej dlžky nerezovej rárky a šířky 1/2 až 2/2 vonkajšieho priemeru nerezovej rárky, pričom v prednej časti nerezovej rárky je na jej vnútornej straně uchytená pružná lístková ružica, ktorej počet pružných lístkov je tri až sedem.These drawbacks are eliminated by a cannula with a lateral opening for the collection of tissue, fat and muscle from a live animal, which is detachably attached to the shearing device by means of a carrier or intermediate element, and is formed of a stainless steel tube. wherein the front of the stainless steel tube has a bevelled front edge. The essence of the cannula according to the invention is that in the stainless steel tube, a longitudinal bore of 1/4 to 2/5 of the total length of the stainless steel tube and a width of 1/2 to 2/2 of the external diameter of the stainless steel tube is formed from its center towards its front. wherein, in the front part of the stainless steel tube, a flexible leaf petal having a number of flexible leafs of three to seven is mounted on its inner side.

Pokrok kanyly s bočným otvorom pódia vynálezu je predovšetkým v tom, že umožňuje rýchly odběr vzoriek svalového a tukového tkaniva od zvierat roznej hmotnost nej kategorie, tým, že sa nevyžaduje odskrutkovávanie kanyly zo striefacieho prístroja po odbere vzorky. Odběr vzorky takýmto sposobom umožňuje rýchle a rovnoměrné zmrazenie vzorky tekutým dusíkom, samotná vzorka zostáva neporušená, pretože nie je potřebné ju z kanyly vytláčať.Advantageously, the progress of the side-opening cannula of the invention is that it allows rapid collection of muscle and fat tissue from animals of different weight categories, by not requiring the cannula to be unscrewed from the shaker after sampling. Sampling in such a manner allows rapid and uniform freezing of the sample with liquid nitrogen, the sample itself remains intact as there is no need to push it out of the cannula.

Na priloženom výkrese je znázorněná kanyla s bočným otvorom na odběr vzorky tkaniva tuku a svalu zo živého zvieraťa.The attached drawing shows a cannula with a side opening for the collection of fat and muscle tissue from a live animal.

Kanyla s bočným otvorom podTa vynálezu je vytvořená z nerezovej rárky 1, ktorá má vo svojej nosnej časti 2 vytvořené odvzdušňovacie otvory 3 a upevňovacie zariadenieThe side opening cannula according to the invention is formed of a stainless steel canister 1, which has in its carrier part 2 vent holes 3 and a fastening device

4. Predná časť nerezovej rárky 1 má skosená predná hranu 8 a na jej vnátornej stene je uchytená například pripájkovaním pružná lístková ružica 7. Počet pružných lístkov 6 pružnej lístkovej růžice 7 je 3 až4. The front part of the stainless steel pipe 1 has a bevelled front edge 8 and a flexible leaf rose 7 is attached to its inner wall, for example by soldering. The number of flexible leafs 6 of the flexible leaf rose 7 is 3 to 5.

7. V příklade podlá výkresu je kanyla s piatimi pružnými lístkami 6. Ďalej je od středu nerezovej rárky 1 vytvarovaný pozdlžny otvor 5 dížky 1/4 až 2/5 celkovej dlžky nerezovej rárky 1 a šířky 1/2 až 2/3 vonkajšieho priemeru nerezovej rárky 1.7. In the example according to the drawing, the cannula with five elastic leaves 6. Further, a longitudinal opening 5 of a length of 1/4 to 2/5 of the total length of the stainless tube 1 and a width of 1/2 to 2/3 of the outside diameter of the stainless steel rárky 1.

Funkčný princip prístroja a kanyly s bočným otvorom podlá vynálezu je v tom, že kanyla sa zavedie pomocou výmetnej náplně strielacieho zariadenia do príslušnej híbky svalového tkaniva. Kanyla sa naplní stlpcom tkaniva, pričom stlačený vzduch vychádza cez pozdlžny oválný otvor 5 kanyly a cez odvzdušňovacie otvory 3 kanyly.The functional principle of the side orifice apparatus and cannula of the present invention is that the cannula is inserted into the appropriate muscle tissue depth by means of a propellant cartridge. The cannula is filled with a tissue column, whereby compressed air exits through the elongated oval opening 5 of the cannula and through the vent holes 3 of the cannula.

Rýchly návrat kanyly s bočným otvorom ovplyvňuje pružina a gumové puzdro, ktoré sá uložené v hlavni strielacieho prístroja. Sučasne volné pružiace lístky v kanyle zabezpečia cddelenie příslušného stlpca tkaniva. Po oddělení ochrannej a podpornej rárky je možné bez vyskrutkovania kanyly cez bočný otvor kanyly tkanivo vybrať a za dodržania hygienických zásad odběr zopakovat'.The quick return of the side-opening cannula is influenced by the spring and the rubber sleeve that are housed in the gun barrel. The currently loose spring leaves in the cannula ensure the separation of the respective tissue column. After separation of the protective and support tube, the tissue can be removed without screwing the cannula through the side opening of the cannula and, following hygiene principles, the collection can be repeated.

Získavanie bioptátov svalu dosiahlo význam nielen pre diagnostiku ochorenia svalu, ale aj pre vyšetrenie kvality masa a při sledovaní hygienických parametrov masa — hladina reziduí po bekových prípravkoch.Obtaining muscle biopsy has not only reached importance for the diagnosis of muscle disease, but also for the examination of meat quality and the monitoring of meat hygiene parameters - the level of residues after bee products.

Ukazuje sa, že takýmto odberom vzoriek svalu bude možné získať včasné informácie na očakávaná kvalitu masa, ktoré v chovatelstve umožnia cielene usměrněná selekciu. Pre tento· áčel sa vyžaduje metoda odběru bioptátov rýchlym, spofahlivým spósobom a bez podstatného ovplyvnenia zvieraťa — stresu zvieraťa.It appears that by taking such muscle samples it will be possible to obtain timely information on the expected quality of the meat, which will allow for targeted, selective selection in the farm. For this head, a method of taking biopsies is required in a fast, reliable manner and without substantially affecting the animal - animal stress.
