Sutures Bioresorbable: iintlobo, ixesha ephilisa

Kwezinye iimeko, ezifana ngexesha utyando, kwakunye emva kokuzalwa efunekayo nokubekwa sutures resorbable. Ngenxa yale nto eyodwa iyasetyenziswa. Kukho iintlobo ezininzi sutures absorbable. Ukuphilisa elithi amanxeba ezinjalo kuxhomekeke kwizinto ezininzi. Ngoko sutures njengokuba bioresorbable ukunyibilika?

Eyona engundoqo iintlobo ze yaseZimbabwe

Ukuze siphendule lo mbuzo, kufuneka ukucacisa ziziphi iintlobo eziphambili namalungu apho. Ngokuqhelekileyo, oko:

1. Internal. ezivuzayo ezinjalo enyanzeliswa phezu ukonzakala ezibangelwa impembelelo ngoomatshini. Loqhakamshelwano umcu kwi ezinjengokwaphuka asebenzise iintlobo ezithile izicwili. Ezi sutures bioresorbable aphilise ngokukhawuleza ngokwaneleyo. Ngokufuthi isicelo abafazi kokuba luzelwe wesibeleko. Kulo mzekelo, zomzimba asifuneki, ekubeni le nxalenye esini akanalo uvakalelo.
2. Yangaphandle. Basenokuba kulahlwa kusetyenziswa izinto resorbable. Emva kokuziswa kwekhithi, yenza beentanda enjalo ikhefu okanye ngexesha asike le perineum, ngokunjalo emva kotyando. Ukuba usebenzisa izinto zesiqhelo, kufuneka ukususa iintsuku 5-7 emva kotyando.

Kubangel 'umdla ukwazi ukuba sutures bioresorbable na onokukuphilisa emva kweeveki ezimbalwa. Konke kuxhomekeke ezahlukeneyo zokufunda nokubunjwa kwayo.

Yintoni na sutures absorbable

sutures Bioresorbable yabaxhasi isoloko ayangenana. Oku kunqabile isetyenziselwa izinto steel ukuphiliswa nxeba leyo iyamelana haydrolisis. Izincomo sutures absorbable, leyo baphelelwe ngamandla abo sele iiyure eziyi-60. Ukunyibilika kwayo ngenxa yokuba sesichengeni:

1. Enzyme aba bakhoyo apha nezihlunu umzimba womntu. Ngamanye amazwi, iiproteni elawula isantya abasabela imichiza.
2. Amanzi. Le yokusabela chemical kuthiwa haydrolisis. Elikulomsonto iginya ngamanzi, akhoyo emzimbeni womntu.

eziethe Synthetic polyglycolide ngomsonto "MedPGA"

Analogs ezinjalo izinto steel zinto "Safil", "Polisorb", "Vicryl".

sutures Bioresorbable emva utyando okanye emva zokubeleka kungenzeka ne ngemisonto "MedPGA". Le izinto steel wenziwa ngokusekelwe poligidroksiatsetilovoy acid. Xa zixhobo ezinjalo camera ye Polymer resorbable. Oku kuyafuneka ukuze kuncitshiswe kwaye umsonto capillarity, kwaye kananjalo ukunciphisa isiphumo sawing ezibangelwa bephethe umbandela ngokusebenzisa kwithishyu.

Bangaphi usombulula ngomsonto "MedPGA"

sutures Bioresorbable abesetwe usebenzisa umsonto "MedPGA" baye ukuthotywa hydrolytic, nto leyo makulawulwe ngokungqongqo. Kubalulekile ukuphawula ukuba ezinjalo izinto lomelele ngokwaneleyo. Emva kweentsuku 18 ngemisonto kugcina ukuya kwiipropati amandla-50%.

Zalisa ukufakwa kwezinto steel kwenzeka kwiintsuku nje emva 60-90. Indlela abasabela ngayo kwinyama komzimba "MedPGA" intambo ayinamsebenzi.

Kubalulekile ukuphawula ukuba izinto steel olunjalo esisetyenziswa ngokubanzi yokuvalwa zonke izicwili, ngaphandle kwabo baphantsi kwempixano, kwakunye ixesha elide akuthethi aphilise. Kudla "MedPGA" ngentambo esetyenziswayo kutyando thoracic kwaye esiswini, izifo, nomchamo, uqhaqho iplastiki kunye amathambo. Nangona kunjalo, akukho awusebenzi ancedisana Wayesoyika sentliziyo.

eziethe Synthetic polyglycolide kumsonto "MedPGA-R"

Analogs ezinjalo izinto steel zinto "Safil Quick", "Vicryl Rapid".

"MedPGA-R" - a vulu zokwenziwa ngokusekelwe poligliglaktina-910. Ezo zinto steel resorbable wambu Polymer. Oku kunciphisa ukuxabana ngexesha indlela vulu ngenxa yenyama yomzimba kunye kunciphisa i nomsonto kunye capillarity. Ngale nto steel kanga sutures bioresorbable.

Zingaphi suture absorbable "MedPGA-R"

"MedPGA-R" - material okuyinto bangenwe yokubola hydrolytic. Ezi imicu ibingenamongo ngokwaneleyo. Emva kweentsuku ezintlanu igcinwe-50% iimpawu zazo namandla. Zalisa Absorption kwenzeka kuphela ngosuku 40-50. Kubalulekile ukuphawula ukuba ijwabu sokusabela umbandela steel "MedPGA-P" ayinamsebenzi. Ukongeza, iintsinga musa ukuba komzimba.

Usebenza a ezibonakalayo ukuze suture ye inwebu yangaphakathi, ulusu, izihlunu ethambileyo, kwakunye kwiimeko xa ufuna inkxaso elifutshane elide inxeba. Nangona kunjalo, kukho ukuxolelwa. nemisonto ezinjalo ayisetyenziselwa kwi inyama Wayesoyika sentliziyo.

eziethe Synthetic polyglycolide kumsonto "MedPGA-910"

Analogue izinto steel abanjalo "Safil", "Polisorb", "Vicryl".

"MedPGA-910" i suture absorbable abunjiiweyo ukusuka poligliglaktina-910. Le nkcazelo steel kananjalo iphathwa kunye ukutyabeka eyodwa kunciphisa "sawing" isiphumo ngexesha sicatshulwa izinto ngokusebenzisa izihlunu, nokunciphisa capillarity kunye nomsonto.

Imihla resorption "MedPGA-910"

Ngoko xa wendele sutures bioresorbable, "MedPGA-910 'enyanzeliswa phezu kwethu izinto steel? nemisonto abanjalo amandla eliphezulu. Noko ke, zibuye ekwehleni hydrolytic. Emva kweentsuku 18 umbandela steel kungonga ukuya kwiipropati amandla 75% emva kweentsuku ezingama-21 - ukuya kutsho kuma-50% emva kweentsuku ezingama-30 - ukuya kutsho kuma-25%, kwaye emva kweentsuku ezingama-70 kukho resorption ngokupheleleyo kwayo.

Le mveliso isetyenziselwa kuvalwa ancedisana ezithambileyo ezingekho phantsi kwempixano, kwakunye nezo aphilisayo ngokukhawuleza, ngeplastiki, thoracic kunye notyando esiswini, izifo, nomchamo kunye amathambo. Awukwazi ukusebenzisa "MedPGA-910" ngenxa suturing le luvo kunye inyama sentliziyo.

Monononit "PDO"

Nucleoside ezinjalo izinto steel azikho kangako. Oku "Biosyns" kwakunye PDS II. zixhobo enjalo ebonakala ngamazinga aphezulu zebhayoloji isibonisi inetrtnosti, nefitilny kunye noncapillary, hydrophobic, musa ukulimaza esikule ngexesha sicatshulwa therethrough, luvela, eqinile, kakuhle ezinithiweyo ubambe node.

Zingaphi ukuzimisela monofilament

Monofilament "PDO" bangenwe haydrolisis. Ngenxa yale nkqubo wavelisa digidroksietoksiuksusnaya acid, excretes ngokupheleleyo. kwiiveki ezi-2 emva kokuba umbandela suture steel igcina ukuya kwi 75% amandla. Zalisa ngamanyala kwenzeka kwisithuba ngemisonto iintsuku 180-210.

Ngokumalunga nesicelo, izinto steel "PDO" lisetyenziswa xa suturing kunye kwizihlunu ezithambileyo uqhagamshelo nawuphi na uhlobo, kuquka ukuze umnqamlezo-ukuhlanganisa izihlunu zomzimba umntwana sentliziyo yakhe, nto leyo kuxhomekeke nokukhula. Nangona kunjalo, kukho ukuxolelwa. Monofilaments ayifanelekanga ukuba isetyenziselwe suturing izihlunu, amanxeba ezifuna inkxaso ukuze iiveki ukuya ku-6, kwakunye abo phantsi layisha phezulu. Awukwazi ukusebenzisa le suture xa ufaka implants, iivelufa intliziyo ngumntu, kwakunye zitho zokwenziwa nemithambo.

Kubaluleke kangakanani iya kuba sutures absorbable?

Okulandelayo, khangela onke ukuba yintoni eyenza sutures bioresorbable emva kokuzalwa, xa wendele, nokuba nkathalo. Musa ukulibala ukuba izinto ezininzi ezichaphazela ixesha lokuphiliswa enxebeni zanyamalala ngokupheleleyo kwayo. Okokuqala kufuneka wazi, koko izinto ngezinto yotyando. Kwiimeko ezininzi, ezi imisonto baqala ukunyibilikisa kwiintsuku 7-14 emva suturing. Ukuze kukhawuleziswe inkqubo, emva kokuba ukuphiliswa ngumboneleli amanxeba angasusa maqhuqhuva. Ukuze siqonde ixesha ukufunxeka imisonto kufuneka icaciswe ngugqirha:

1. Ziziphi athungwe.
2. Ziziphi izinto zaye zaveliswa vulu.
3. ixesha nokonakala engumzekelo le suture.

Ekupheleni

nemisonto Bioresorbable adla ngokusetyenziswa xa suturing manxeba yokusebenza, apho ibekwe ingxenye yaso kwithishyu, kwakunye kumphezulu esikhumbeni. Ngokomzekelo, xa nokufakelwa amalungu omzimba.

Le nkcazelo efanayo ngotyando lusetyenziswayo xa suturing amanxeba kunye Ukophuka ifunyenwe ngethuba lokubeleka. Kulo mzekelo, zininzi izifundo ziye zaqhutywa. iziphumo zabo yabonisa ukuba suture eyenziwe polyglycolic acid, liyalahleka ngokupheleleyo kwiinyanga nje ezine, yaye umbandela ngokusekelwe polyglactin - ezintathu. Ngoko sutures bioresorbable liza kubamba imiphetho inxeba phambi ukugqiba impiliso, uze emva koko ngokuthe ngcembe ukuqala ukwaphula phantsi. Ukuba umsonto ixesha elide bayasindiswa akhulule ukungakhululeki, kufuneka ufune uncedo kugqirha okanye ukuya gqirha.
