Description

IS 25 2 ascending aerta in cerenery artery hypeee surgery, perticuiariy in eerhecceee CABG surgery. A fåret aspect et the invehtien inciudee e vescuiar eneetemeeis etepie. A itret confrgnretien has twe parts: an eneher member, terrning the attaeh~ ment with the target veseei wait and e eeupiing member, terrning the attachment with the hypeee gren veeeei. The anastemesie ie cempieted hy the counting rnenther, with the draft veesei attached, inte the enchor member. A eeeend eeniiguretien combines the function ef the ancher rnenther and the ceuhiing nrernher inte enepiece eneeterneeie stapie.
This device requires that the eenpiing member during the operation hee te he attached te the grett veseei, which might he tirrte censurning. Furthermore the attachment et the counting member te the grett veseei requires iarge preeisien end eidii ironi the eurgenn in erder te niinimize the risk ter ieeking.
US 6 524 322 diseieees en enasterneeis device ter jeining veeseie, in the tiret piece jnining ene end ot e gratt veesei te a target veeeei at en nnening rnede in the wait thereet. The eneetemesie device cdrrrpriees e tu huier body en which en enter iiange, which cernee inte cnntaet with the outside et the wei! ot the target veseei areund the opening, end en inner iienQe, which comes inte contact with the inside et the wait et the target veeeei around the opening, ere errenged. The inner tiertge ie made un nt e number ei errne which ere ehie to rneve frem en extended peeitien, ieceted in the extensien et the tuhtiiar body, under the infiuence of e pre tensien inte e peeition extending in the iaterei direetien with respect to the tuhuiar hardy, efter the pretensien hes been reieaeed, in erder te terrn the inner tienge.
Aten this devirze ineiudee the sten et' etteching the tnhuiar counting body to the graft veseei during the operation end thus enteiie drewheeke ef eirniiar kind es these reiating te US 6 iii 321.
The ohjeet ei the present inventien ie te prevíde en anestomesie device for end te side eneetentnsis hetvreen e grett veeeei end e naturai veeeei in the human hedy which reddcee demands on time and eiriii ef the surgeen es tar es eoeaihie and nvereernes the drewhecirs reieted te prier ert attempts in this respect.
Summary* of invenrinn The object of the inventien is achieved in that an anesternesia device of the kind initieiiy specified insändes the specific features thet et ieeet e tiret et' seid ende ie provided with e ring-Shaped counting unit integrated with the tehuier hedy NJ u: u: Ca 3 and having connectinn means arranged for counting in a compienientary ring- shaped counting unit.
Tha cievice raciicaiiy reducera the nnmhiexšty and time when inining a grnft vessei to a naiiirai hittad væssni ar the titta in cørhparisøri with traditirsnai surgery.
Furtherrrinre a minimum ut pinces are required tor the anastomnsis, oniy hun pinnen ara requireä, narneiy the grått vessei and an attachment :initiera at tha target vesaei. The iirnitefi nunthnr ni pinnen required iteaüs in a very secure and rapid cineration, which makes thre reqtiiremnnt on sitiii and nxpnrienfte ni the sur~ genre tens crucziai. Since the cniipiing unit for attaching the gratt vessei tr: the target vessni is an intngratnri part nt the grait vessei itseii, the need inr attaching the gratt vessæi in a counting unit is eiirninateü whisn further redunes the nnhratinn time and the risii: inr mistakes. As sann as a chmpiernnntary counting unit is attached tt: the target vessei oniy a simpie ping-in sten is requireci. the device is narticiiiariy stiitahie inr nnwtrnsirin anasiontasis but it is in be uncir-:rstonci that it aisn can he anpiiad inr enä-tn-end ahastnrnnsis where a grait vessei is irivnived.
With "sornpierneritary" is meant that the cnupiing units match each nther such thai they tngnther forms a tight counting, ng. the cnuniing units are ut main and fnntaie type, respectiveiy, Accnrding to a preinrrtid ernhndimerii aisn the seccind anti n? the graft vessei is prnvidnd with a secnhti ring-shapnd couniing unit integrated with the ttihutar body anü having nnnnnctinn means arranged inr cnitpiing to a cørnpiemerh tary ririg-snannci cnupišng.
This emhodirnent aiinws a correspnnding simpin and :inte ccnnectinn at both enda nt the gratt vessei with a respective target væssei.
Accnrding in a further preferred nmhndirrient the first and ancoriri counting units are nither iáentinni ar cømpiernentary.
This emhndirnent further sitnpiifies the device and the operatiøn when æappiying it, dun in the uniinrrn cnnstructioh. 'thus the attachment stieps when attaching the enda of the gratt vessei in a respacztive target vessei wiii ha :airnnst the same.
Acrznrdihg in a further enfihridirrrent the tuhuiar hndy inciucies at iæast hivo separate tuhiriar snctinns and at ienst finn intercnnneciion device, each iniercøw necticin device having a first and second ring-shaped counting part, each being 220 h.) 1.:: Ii Ü 4 intngratnü with a respective tubuiar unit, and the twr: ring-shaped cøupiing parts of the intercønnecišon device being ræieasabiy intercnnnncind.
The iengih required inr the grait vessei is diifnrent inr diiinrent kinds of appiications in the hurnnn hndy ann rnay aisn van; inr the same kind nt operation 'ironi nnn parsnn in another. The iength e? the graft vessei thus is to bn adapted in the actuai cnnditinn. With a grått vessæi huiit up by a piurniity oi seetions accørding in this enihødirnent a vnry sirnpie way ni anapting the iengih is friterad, The surgeøn rnereiy has to ttisnngagn the ræinasabie intercnnnnction ánvice in have a shnrtær gran vessei, thnrehy any need tr: cut the gran vessei inte the appropriate iength in eiirninatnd.
Accnrtiing to a further preterreci enibodiment tha first ring~shaped part ni the intnrconnnctiøn device is icienticni to the ring-shnpnd unit attached ts said first and and in that the secnnn ring-Shaped part ni the intercnnnæciinn device is identi- cat in the ringæhapntai unit attached in said sncnnd anti.
This ærnbndimnnt has the advantage that ii the surgnnn finans in shnrten the grnit vessei hy saparating a portion thnrnni this portion witi have its tina nncis irïenticai in the czcirnpintn grait vessai.
Arzcøráing tr: a ttirther preferred ernbndiment the cnnnectinn means ni each ring-stannad counting unit is either rnaie connectinn means cr temnin cnnnectiøn means, the main cnnnnctinn nia-rann inrziutiing at inast ivrn axiniiy extnnding members, each member having n tree enn, and the tranaain cznnnectiøn means insättning at iaast tvvn axiaiiy directeri recaiving ønenings, the axiaiiy riiirected recniving npenings ut a ientaie cnnnectinn means being arranges før axiaiiy receiving the free enda of the axiaiiy extending members n? a main sanne-ar:- iinn means, each axiaiiy extending member being arranged in he ahie in Snap inte: a tracking position in nne ni said ræcnšving :meningar nt a ternaie cnnnectinn means, By nrnvitziing the cntiniing means as a main or 'ir-irnain cnupiing means in this way the cnnnectinn ni the gran vessei in the target vessei having a campin- rrinntary counting unit can ha sinne very easy, rapid anti with ntirttrnizeti risk inr ršefauit. When the members have snappeü intn the ræceiving upenings the nxiaiiy Banking eiírninnins the risk thai the grait vessei wiii innsen irnrn the nnupiing unit of tha gran væssei.
Accorfiing tn a further preferred ernhndimnnt nt the inventitin an anastit» rnnsis systern inniuáes a gratt vassa! according in the inventinn, in narticuiar in 15 26 5 any nt the preferred eniboniments thereet, which systern further ineiudes n Sena» rate ršng-shened ceupiing unit having cnrinection means that is nnmpiementary in the ringnnened ceuniing unit ef the grett veesei.
Therehy a cernniete systern inr the cnrinectinn et a gratt vessei in n target iressei is provided. Prnviding n system incitiöing hnth the cnmpnnenie eiiminates any risk for rnienfiatch between the nnuniing unit et the grntt veesei and the ring» shened unit to which it ie te he cenneeted.
Actzerding in a further preferred emhedirraent the invented systern ineiutzies that the separate ringehapeü cnnpiing unit inciuties ræenetratien means arranged te nenetrnte the wait et n vessei for atiaching the separate ring~ehanen counting unit to the vessei. this way of attaehing the eenarete ring-shared cnuniing unit is time effective and eiiews n very secure attachment.
Actzerding ie a further preterreri embeciiment the nenetretinn means insändes n veesei receiving surface inciuciing en area having e rnnghneee with a inrge number nt srnaii share nrnjeeišnne errahged tn nartiy nerietrate the wait et said veesei withnut teaching thrnugh said wait.
Since the nrnietztinns tic net cnrnnieteiy reach iiireugh the wait they ifviii not reach the inside of the connecteti vessei enci there wiii he ne onening tecing the interier of the veseei that cnuid cause inieetien nr the iiite.
