I-Stapler sisixhobo sokuqala se-suture emhlabeni, esiye sasetyenziselwa i-anastomosis yesisu malunga nenkulungwane.Kwakungekho kude kube ngo-1978 ukuba i-tubular stapler yayisetyenziswa ngokubanzi kwi-gastrointestinal operation.Ngokuqhelekileyo yahlulahlulwe ibe yi-staplers yexesha elinye okanye ezininzi, ezithathwe kwamanye amazwe okanye zasekhaya.Isetyenziselwa ezinye iindlela zonyango kwizixhobo zemveli ze-suture manual, ngenxa yophuhliso lwenzululwazi yanamhlanje kunye nobuchwepheshe kunye nokuphuculwa kobugcisa bokuvelisa, ukusetyenziswa kwekliniki yomgangatho we-stapling inokwethenjelwa, kulula ukuyisebenzisa, iqinile, i-elastic, ilungile ngokukodwa i-suture iyakhawuleza, umsebenzi olula kunye neziphumo ebezingalindelekanga ezimbalwa kunye neengxaki ezifana iingenelo, kwakhona yenza elidlulileyo ayinakususwa ukuba isilonda resection utyando ithumba.
I-stapling, kubandakanywa nendlu, intonga yeziko kunye netyhubhu, intonga ephakathi kwityhubhu yokutyhala, indawo ephambili yangaphambili ixhotyiswe nge-screw cap, isiphelo sangasemva ngokusebenzisa iqhosha lokulungelelanisa ekupheleni kwesikrufu sokudibanisa kunye neqokobhe, iqokobhe langaphandle liphefumlelwe isibambo, phefumlela umqheba woqhagamshelo olusebenzayo ngehenjisi kunye neqokobhe, elinophawu olu: oluchazwayo lwe-stapling ngekhonkco, Iintonga ezintathu zokuqhagamshela ziqhagamshelwe ngokulandelelana komqheba wokuvuselela, udonga lwangaphakathi lweqokobhe kunye netyhubhu yokutyhala, kunye nesinye isiphelo sentonga ezintathu ezidibanisayo. idityaniswe nehenjisi enye eshukumayo;Iintambo ezintathu zokudibanisa zendlela yokudibanisa zibandakanya intonga yamandla, intonga yokuxhasa kunye nentonga ehambayo;Intonga yamandla kunye nesiphatho sokuvuselela sixhomekeke;Ihinge eshukumayo idityaniswe phakathi kwentonga exhasayo kunye negobolondo;Ihinge eshukumayo idityaniswe phakathi kwentonga eshukumayo kunye netyhubhu yokutyhala.I-stapler yemodeli esebenzayo ineenzuzo zesakhiwo esilula, ukusebenza kakuhle kunye nokuzinza okuqinileyo.
Ubume be-stapler
I-Digestive tract anastomat push rod edityaniswe kwisakhiwo somsiki we-annular, kubandakanywa intonga yokutyhala, kunye nentonga yokutyhala esisigxina yemela elisetyhula, echazwe umda wangaphandle weseti yemela ejikelezayo ibe nolwalathiso olungaphezulu kwesinye lucwangciswe kunye nomjikelezo we-ejector pin, kuchazwa enye isiphelo intonga push yimela setyhula ezizinzisiweyo, ngenxa intonga push zimiliselwe ngesiphelo esinye sesetyhula imela, ngoko imela setyhula kunye concentricity eliphezulu intonga push, kwinkqubo yokusika umbutho, Imela umsesane ungahlala. embindini ngokutyibilikayo kwaye izinga lempumelelo yokusebenza liphezulu.
I-Digestive tract anastomat ejector pin yesixhobo, kubandakanywa i-ontology ye-6 ye-nail warehouse, i-ejector pin 1 ye-ontology, i-ejector pin 1 ye-ontology, icala lokuqala lomngxuma 5 isikhonkwane isitora 7 kwiziphelo zombini zesebe kunye nodonga lokuqala lwesikhokelo 9 ngokulandelelana, udonga lwecala lesibini 8 Iziphelo zombini zeSebe zinodonga lwesikhokelo sesibini esili-10 ngokulandelelanayo, ngokufanayo udonga lwesikhokelo sokuqala 9, i-10 yesibini yodonga lwesikhokelo sokuhlangana kunye ne-arc transition, Isikhokelo sokuqala sodonga lwe-9 kunye nodonga lwesibini lwesikhokelo i-10 kwisiphelo esifanayo zicwangciswe kwindawo enye. isikali esilinganiselweyo;Xa kukho utshintsho oluncinci kwijometri yokuthunga, inokufumaneka ngokukhuselekileyo emngxunyeni womgqomo wokuthunga ngendima yodonga lwesikhokelo, ukuqinisekisa ukuba ububanzi beshiti le-nail sheet bukhulu kunobubanzi be-nail sheet. isithsaba sokuthunga, ukwenzela ukuba imilo yokuthunga ilungile.
Isakhiwo sokudibanisa i-cone ye-puncture kunye nesihlalo sesikhonkwane se-stapler digestive tract sibandakanya isihlalo sesikhonkwane kunye ne-puncture cone.Isihlalo sesikhonkwane sigxininiswe nge-clamp spring, kunye ne-puncture cone ifakwe phakathi kwemithombo ye-clamp, kwaye i-clamp spring ibamba i-cone ye-puncture.Ngokuxhomekeke kwi-spring clamping force ye-clamping spring, isihlalo sezikhonkwane sinokudibaniswa ngokuthembekileyo okanye sahlulwe kwi-cone ye-puncture, ekhuselekileyo ukuyisebenzisa kwaye ikulungele ukuyifaka.
Umgudu wokugaya ukutya kwe-anastomat isixhobo sokulawula isantya esiphindwe kabini, kuqukwa ne-ontology yestapling, kwaye ichaze i-ontology yokumisela inokujika ukuze idibanise i-ontology yokutshintsha, i-ontology kunye neqhina elichaziweyo eliqhagamshelwe ngomsonto ojijwayo, iplagi ye-screw ye-ontology yokucofa ichazwe kwigumbi elingaphakathi, umphambili we-ontology. intonga Screw idityaniswe stapling kulo mgodi kumbindi womzimba, Isikrufu sinecandelo lokuqala intambo kunye icandelo intambo yesibini edityanisiweyo, kwaye pitch yecandelo intambo yokuqala mkhulu kunaleyo icandelo intambo yesibini.Inganciphisa ngokukhawuleza umgama phakathi komgqomo wesikhonkwane kunye nesihlalo sezikhonkwane, kwaye icandelo lesibini lentambo yesilayidi lihambelana nomzimba we-knob, okwenza ukuba i-screw ihambe kancinane xa iqhosha lijikeleza, eliluncedo ekusebenzeni kwendlela yokugaya.
