I-Stapler sesona sityalo sokuqala emhlabeni, esiye sasetyenziselwa i-anastomosis yesisu malunga nenkulungwane.Kuze kube yi-1978, i-tubular stapler yayisetyenziswa ngokubanzi kutyando lwesisu.Ngokuqhelekileyo yahlulahlulwe kwi-staplers elahlayo okanye esetyenziselwa izinto ezininzi, ezisuka kumazwe angaphandle okanye zasekhaya.Sisixhobo esisetyenziselwa amayeza ukutshintsha i-suture ye-manual yendabuko.Ngenxa yophuhliso lwenzululwazi yale mihla kunye nobuchwepheshe kunye nokuphuculwa kobugcisa bokuvelisa, i-stapler esetyenziswa kuqheliselo lwezonyango ineengenelo zomgangatho othembekileyo, ukusetyenziswa ngokufanelekileyo, ukuqina kunye nokuqina okufanelekileyo.Ngokukodwa, ineenzuzo ze-suture ekhawulezayo, ukusebenza okulula kunye nemiphumo embalwa kunye neengxaki zotyando.Ikwavumela ukuba kugxilwe kuqhaqho lotyando lwethumba olungachaswanga kwixesha elidlulileyo.
Intshayelelo kwi-stapler
I-Stapler sisixhobo esisetyenziselwa amayeza ukutshintsha i-suture manual.Umgaqo wayo oyintloko wokusebenza kukusebenzisa izikhonkwane ze-titanium ukuqhawula okanye izicubu ze-anastomose, ezifana ne-stapler.Ngokutsho kobubanzi obuhlukeneyo besicelo, inokohlulwa ibe yi-stapler yesikhumba, i-digestive tract (umqalanzo, i-gastrointestinal, njl.) .
Xa kuthelekiswa nomthungo wesandla oqhelekileyo, isixhobo sokuthunga sesixhobo sineenzuzo ezilandelayo:
Ukusebenza kulula kwaye kulula, ukonga ixesha lokusebenza.
Ukusetyenziswa okukodwa, kunqande usulelo olunqamlezayo.
Sebenzisa izikhonkwane ze-titanium okanye iinzipho zensimbi ezingenasici (i-skin stapler) ukuthunga ngokuqinileyo kunye nokuqina okuphakathi.
Ineziphumo ebezingalindelekanga ezimbalwa kwaye inciphisa ngempumelelo iingxaki zotyando.
I-stapler yesikhumba inezi mpawu zilandelayo eziphawulekayo: ukusebenza okulula kunye ne-suture esheshayo;Ukunciphisa ixesha lokusebenza kunye nokuphucula izinga lokuguqulwa kwegumbi lokusebenza;Inxeba lincinci kwaye inxeba lihle;Isikhonkwane sokuthunga esikhethekileyo, esilungele inxeba loxinzelelo, ukuhambelana kakuhle kwe-histocompatibility, ukuphendula kwentloko engenazingcingo;Akukho ukunamathela kunye ne-scab yegazi, kwaye intlungu yokutshintsha ukugqoka kunye nokususwa kwezipikili zincinci;Akukho ukuncamathela kunye nokutsiba, ukusebenza okuzinzileyo.
Iimpawu ze-prepuce cutting stapler: ukusebenza okulula kunye nexesha elifutshane lokusebenza;Ukopha okuncinci kunye neentlungu ezincinci;I-edema ye-postoperative yayincinci;I-staples yawa ngokuzenzekelayo emva kokuhlinzwa, kwaye kwakungekho mfuneko yokubuyela esibhedlele ukususa i-stitches kunye namakhonkco;Uqhaqho lotyando luqhelekile kwaye luhle emva kokuphiliswa.
Iimpawu ze-purse string stapler: ukulahla ukuphepha ukusuleleka kwintsholongwane;Ngocingo lwesikhwama olwakhelwe ngaphakathi kunye nesikhonkwane se-titanium, isikhwama similiselwe ngokuzenzekelayo ngaphandle kwentambo, ekhawulezayo kwaye ilungele ngakumbi Ukusebenza kulula kwaye ixesha lokusebenza lifutshane.
Iimpawu ze-stapler ezilahlwayo ezilahlwayo: indlela yokumisa ilula kwaye ilungile, kwaye ixesha lokusebenza lifutshane;Imiqolo emithathu yezikhonkwane ze-suture zicwangciswe ngokudibeneyo ukuthintela ukopha;Ucingo lwe-titanium oluphuma kumazwe angaphandle lusetyenziselwa ukunika amandla angcono kunye namandla okuqina;Inaliti yokumisa edibeneyo ingasebenza ngesandla okanye ngokuzenzekelayo, ekulungele ukulungelelanisa izicubu ze-anastomotic.
Iimpawu zesakhiwo se-stapler
I-stapler ibandakanya igobolondo, intonga ephakathi kunye netyhubhu yokutyhala.Intonga ephakathi ibekwe kwityhubhu yokutyhala.Isiphelo sangaphambili sentonga ephakathi sixhotyiswe ngekhava yesikhonkwane, kwaye isiphelo sangasemva sidibaniswe ne-knob yokulungelelanisa ekupheleni kwegobolondo nge-screw.Umphezulu wangaphandle weqokobhe uxhotyiswe ngesiphatho sokuvuselela, esidityaniswa ngokushukumayo kunye neqokobhe ngehinge.Isici sayo kukuba: i-stapler ixhotyiswe ngesixhobo sokudibanisa intonga, kwaye iintonga ezintathu ezidibanisayo zidibene ngokulandelelana kunye nesiphatho sokuvuselela, udonga lwangaphakathi lwegobolondo kunye netyhubhu yokutyhala, Kwaye enye isiphelo sentonga ezintathu ezidibanisayo zixhunyiwe. ihenjisi efanayo eshukumayo;Iintonga ezintathu zokudibanisa zendlela yokudibanisa ziquka intonga yamandla, intonga yokuxhasa kunye nentonga eshukumayo;Intonga yamandla ixhonywe ngesiphatho sokuvuselela;Intonga yenkxaso kunye negobolondo idibaniswe yihinge ehambayo;Intonga ehambayo idityaniswe netyhubhu yokutyhala ngehenjisi eshukumayo.I-stapler yemodeli esebenzayo ineenzuzo zesakhiwo esilula, ukusebenza kakuhle kunye nokuzinza okuqinileyo.
Isakhiwo sokudibanisa phakathi kwentonga yokutyhala kunye ne-annular knife ye-digestive tract stapler ibandakanya intonga yokutyhala kunye ne-annular knife edibeneyo ngokusisigxina kunye ne-push rod.Ubuninzi bezikhonkwane ezityhalayo ezicwangciswe ecaleni kwesangqa zicwangciswe kumphandle wemela ye-annular.Esinye isiphelo semela ye-annular sifakwe kwi-push rod.Ngenxa yokuba isiphelo esinye semela ye-annular sifakwe kwi-push rod, i-concentricity ye-annular knife kunye ne-push rod iphezulu.Kwinkqubo yokusika izicubu, imela ye-annular inokuhlala phakathi kakuhle, Ukuphumelela kokuphumelela komsebenzi kuphezulu.
Isixhobo sokutyhala isikhonkwane se-stapler digestive tract sibandakanya umgqomo we-nail 6 kunye ne-nail pushing sheet sheet 1. Iziphelo ezimbini zodonga lwecala lokuqala 7 lomngxuma we-nail bin 5 ngokulandelelana zibonelelwe ngodonga lokuqala lwesikhokelo 9, kunye ne iziphelo ezimbini zodonga lwesibini lwecala le-8 ngokulandelanayo zibonelelwe ngodonga lwesibini lwesikhokelo 10. Udonga lokuqala lwesikhokelo 9 kunye nodonga lwesibini lwesikhokelo se-10 kwisiphelo esifanayo kunye ne-arc inguqu kwi-intersection.Isikhokelo sokuqala sodonga lwe-9 kunye nodonga lwesibini lwesikhokelo se-10 kwinqanaba elifanayo zicwangciswe ngokulinganayo;Xa kukho utshintsho oluncinci kubungakanani bejometri yestaple, inokuthi ibekwe ngokuzinzileyo kumngxuma we-staple bin ngomsebenzi wodonga lwesikhokelo, ukuze kuqinisekiswe ukuba ububanzi bepini yokutyhala inkulu kunobubanzi isithsaba sesigxina, ukwenzela ukuba i-staple yenziwe kakuhle.
Isakhiwo sokudibanisa phakathi kwe-cone ye-puncture kunye nesiseko sesikhonkwane se-stapler digestive tract sibandakanya isiseko sesikhonkwane kunye ne-puncture cone.Isiseko sesikhonkwane sigxininiswe nge-snap spring, i-cone ye-puncture ifakwe phakathi kwemithombo ye-snap, kwaye i-snap spring ibamba i-cone ye-puncture.Ukuxhomekeka kwi-spring clamping force ye-snap spring, isihlalo sezikhonkwane sinokudibaniswa ngokuthembekileyo okanye sahlulwe kwi-cone ye-puncture, ekhuselekileyo ukuyisebenzisa kwaye ikulungele ukuyifaka.
