Sutures Bioresorbable: izinhlobo, isikhathi ephulukisa

Kwezinye izimo, ezifana phakathi nokuhlinzwa, kanye ngemva kokuzalwa edingekayo ukunqunywa sutures resorbable. Ngenxa yalesi material ekhethekile isetshenziswa. Kukhona izinhlobonhlobo eziningi sutures absorbable. Ukuphulukisa eside yamanxeba enjalo kuxhomeke ezicini eziningi. Ngakho sutures njengoba bioresorbable chaza?

Izinhlobonhlobo eyinhloko yaseZimbabwe

Ukuze siphendule lo mbuzo, kubalulekile ukucacisa yiziphi izinhlobo eyinhloko emalungeni khona. Ngokuvamile, kuba:

1. Langaphakathi. ezivuzayo ezinjalo esikhulu ukulimala okubangelwa umthelela lokukhanda. Ukuze yokuxhuma izicubu ngesikhathi ukwa ukusebenzisa izinhlobo ezithile kwezicubu. Lezi sutures bioresorbable ukuphulukisa ngokushesha ngokwanele. Avame isetshenziswa abesifazane emva kokubeletha wesibeletho. Kulokhu, izinzwa kungadingeki, njengoba le ngxenye umthondo elingenalo ukuzwela.
2. Yangaphandle. Zingase futhi waphonsa usebenzisa izinto resorbable. Ngemva kokubeletha, wenze ezivuzayo enjalo ikhefu noma ngesikhathi asike izidumbu zabantu we perineum, kanye nangemva kokuhlinzwa. Uma usebenzisa i material abavamile, kuyadingeka ukuze uyisuse izinsuku 5-7 emva kokuhlinzwa.

Kuyaphawuleka ukuthi sutures bioresorbable angashintsha ngemva kwamasonto ambalwa. Konke kuncike ezihlukahlukene zezinto ezibonakalayo nezingokomoya ngezithako zawo.

Kuyini sutures absorbable

sutures Bioresorbable cishe njalo kuyenzeka ihlangane. It is kuyaqabukela isetshenziselwe isilonda sisheshe siphole impahla kuhlinzwa emelanayo hydrolysis. Kubhekwe sutures absorbable, okuyinto amandla akhe kakade at amahora 60. Ukuqedwa kwayo ngenxa ukuchayeka:

1. Enzyme abakhona emisipheni yomzimba womuntu. Ngamanye amazwi, amaphrotheyini ezilawula futhi ukusheshisa zamakhemikhali.
2. Amanzi. Cishe le ndlela yokusabela chemical libizwa hydrolysis. Kulesi ngentambo ubhujiswe amanzi, okuyinto ekhona emzimbeni womuntu.

Zokwenziwa Ababazi bakha polyglycolide ngentambo "MedPGA"

Analogs izinto ezinjalo kuhlinzwa kukhona "Safil", "Polisorb", "Vicryl".

sutures Bioresorbable emva kokuhlinzwa noma ngemuva kokubeletha kungase zenqane lokuluhlaza "MedPGA". Lokhu kwaziswa kuhlinzwa senziwa okusekelwe poligidroksiatsetilovoy acid. Ngo ezinjalo sesigcilikisha camera ka-polymer resorbable. Lokhu kuyadingeka ukuze kuncishiswe futhi intambo yefilakisi capillarity, futhi ukunciphisa umphumela sawing kubangelwa abathwele impahla ngokusebenzisa izicubu.

Bangaki kuxazululwa ngentambo "MedPGA"

sutures Bioresorbable okuyinto ayebekelwe usebenzisa intambo "MedPGA" bayothola nokucekelwa hydrolytic, okuyinto lilawulwa. Kuyaphawuleka ukuthi izinto ezinjalo kuba ngokwanele. Emva kwezinsuku 18 lokuluhlaza ukugcina up 50% amandla izici.

Qedela ukumuncwa impahla kuhlinzwa kwenzeka kuphela ngemuva kwezinsuku ezingu 60-90. Basabela kanjani ezicutshini zomzimba kuya "MedPGA" ngentambo azinakwa.

Kuyaphawuleka ukuthi impahla kuhlinzwa esinjalo kabanzi kuvalwe zonke izicubu, ngaphandle kwalawo bangaphansi ukungezwani, kanye isikhathi eside ingaluqedi. Ngokuvamile "MedPGA" ngentambo ezisetshenziswayo ekuhlinzeni thoracic futhi besisu, ukusebenza kwayo nezifo zabesifazane, Urology, ukuhlinzwa kokulungisa ukubukeka kanye amathambo. Nokho, asisebenzi kwezicubu sezinzwa futhi senhliziyo.

Zokwenziwa Ababazi bakha polyglycolide ngentambo "MedPGA-R"

Analogs izinto ezinjalo kuhlinzwa kukhona "Safil Quick", "Vicryl Rapid".

"MedPGA-R" - a ntambo zokwenziwa wenza ngesisekelo poligliglaktina-910. Okubalulekile okunjalo kuhlinzwa resorbable embozwe polymer. Lokhu kunciphisa ukuxabana phakathi ukudlula ntambo ngokusebenzisa izicubu zomzimba futhi kunciphisa ntambo futhi capillarity. Ngalesi impahla kuhlinzwa zingasetshenziswa sutures bioresorbable.

Bangaki suture absorbable "MedPGA-R"

"MedPGA-R" - material okuyinto ukungenwa noqhekeko hydrolytic. Lezi imicu uqine ngokwanele. Ngemva kwezinsuku ezinhlanu agcinwayo 50% bezikhwepha zabo izakhiwo. Qedela ukumuncwa kwenzeka kuphela ngosuku 40-50. Kuyaphawuleka ukuthi izigaxana yokusabela kuya impahla kuhlinzwa "MedPGA-P" azinakwa. Ngaphezu kwalokho, imicu musa abangele komzimba.

Lusebenza material for the suture ka nolwelwesi lwamafinyila, isikhumba, izicubu zomzimba ezithambile, kanye ezimweni lapho udinga ukusekelwa yesikhashana isilonda. Nokho, kunokuningi okungakhulunywanga ngakho. lokuluhlaza ezinjalo azisetshenziswa ku izicubu sezinzwa futhi senhliziyo.

Zokwenziwa Ababazi bakha polyglycolide ngentambo "MedPGA-910"

Analogue ukwaziswa okunjalo kuhlinzwa kukhona "Safil", "Polisorb", "Vicryl".

"MedPGA-910" kuyinto suture absorbable bhila kusukela poligliglaktina-910. Indaba kuhlinzwa nayo ziphathwe enamathela ekhethekile esehlisa "sawing" umphumela phakathi ukudlula impahla ngokusebenzisa izicubu, nokwehlisa capillarity futhi intambo yefilakisi.

Izinsuku resorption "MedPGA-910"

Ngakho lapho matasa sutures bioresorbable, "MedPGA-910" ngaphezulu kakhulu indwangu kuhlinzwa? lokuluhlaza ezinjalo amandla aphezulu. Nokho, kunjalo futhi kuncike nokucekelwa hydrolytic. Emva kwezinsuku 18 okokusebenza kuhlinzwa Ungagcina kuze ku-75% amandla izakhiwo emva kwezinsuku 21 - 50% ngemuva kwezinsuku ezingu-30 - kufike ku-25%, kanye ngemva kwezinsuku 70 kukhona resorption okuphelele kwayo.

Lo mkhiqizo isetshenziselwa kuvalwe kwezicubu ezithambile ukuthi awekho ngaphansi kwadambisa isimo esasishubile, kanye nalabo aphilisayo ngokushesha, ipulasitiki, thoracic nokuhlinzwa besisu, ukusebenza kwayo nezifo zabesifazane, Urology kanye amathambo. Awukwazi ukusebenzisa "MedPGA-910" ngenxa suturing emsipheni nezicubu zenhliziyo.

Monononit "PDO"

Analogue izinto ezinjalo kuhlinzwa akuzona okungaka. Lokhu "Biosyns" kanye PDS II. sesigcilikisha okunjalo zinezikhathi okusezingeni eliphezulu begazi inkomba inetrtnosti, nefitilny futhi noncapillary, hydrophobic, musa ona ijwabu ngesikhathi ndima therethrough, bakwazi ukubhekana nokuhlupheka, eqinile ngempela, kahle wathungela bese ubamba engeyokuqala.

Bangaki ukuzimisela monofilament

Monofilament "PDO" ukungenwa hydrolysis. Ngenxa yalokho yale nqubo ekhiqizwa digidroksietoksiuksusnaya acid, excretes ngokugcwele. 2 amaviki emva kuhlinzwa suture impahla azigcina 75% amandla. Qedela nokonakala kwenzeka ngaphakathi lokuluhlaza izinsuku 180-210.

Ngokuphathelene isicelo, indaba kuhlinzwa "PDO" isetshenziselwa suturing futhi izicubu zomzimba ezithambile uxhumano kwanoma yiluphi uhlobo, kuhlanganise i-cross-ngokuxhumanisa ezicutshini zomzimba senhliziyo yengane, okuyinto angaphansi sokwanda okwengeziwe. Nokho, kunokuningi okungakhulunywanga ngakho. Monofilaments ayifanele suturing izicubu, izilonda ezidinga usekelo-6 amasonto, kanye nalezo babhekana imithwalo eliphezulu. Awukwazi ukusebenzisa i-suture uma ufaka izimila, yokufakelwa inhliziyo valve, kanye zokwenziwa lokufakelwa kwezitho semithambo.

Kubaluleke kangakanani-ke kuyoba sutures absorbable?

Okulandelayo, sibheke bonke ngokuthi kuyini a sutures bioresorbable emva kokubelethwa, uma amuncwa umzimba, ukuthi anakekele. Ungakhohlwa ukuthi izici eziningi ezithinta isikhathi isilonda sisheshe siphole futhi ukunyamalala okuphelele kwayo. Okokuqala odinga ukukwazi, kulokho izinto ezenziwe impahla kuhlinzwa. Ezimweni eziningi, imicu uqale ukuncibilikisa izinsuku 7-14 emva suturing. Ukuze zihambisane inqubo, ngemva ukuphulukiswa amanxeba umhlinzeki Ungasusa ngamaqhubu. Ukuze sithole inkathi ukumuncwa sendikimba kufanele licaciswe udokotela:

1. Yini yaseZimbabwe babe.
2. Yini impahla zavezwa ntambo.
3. Okuyisibonelo nokonakala nesikhathi suture.

Ekupheleni

lokuluhlaza Bioresorbable avame ukusetshenziswa suturing izilonda ku yokusebenza, okuyinto zitholakala izingqimba ezijulile izicubu, kanye phezu kwesikhumba. Ngokwesibonelo, e isitho Ukufakelwa.

Lesi sihloko esifanayo kuhlinzwa esetshenziselwa suturing amanxeba kanye waphuka etholwe ngesikhathi sokubeletha. Kulokhu, eziningi izifundo sezenziwe. Imiphumela ababeziphethe ngayo yayibonisa ukuthi suture eyenziwe polyglycolic acid, ubalekela endaweni ngokuphelele kwezinyanga ezine nje, futhi impahla ngesisekelo polyglactin - ezintathu. Ngakho sutures bioresorbable izobamba emaphethelweni isilonda ngaphambi ukuqedela ukuphulukisa, bese kancane kancane uqale ziwohloke. Uma intambo isikhathi eside bayasindiswa futhi ukuletha ukungakhululeki, kufanele ufune usizo kusuka udokotela ohlinzayo noma ukuya kudokotela.
