Kuwe ophishekela ubuhle, ubuhle bezokwelapha intambo ye-pdo ingase ibe yigama eliyinqaba nelikhangayo. Namuhla, ake sembule imfihlakalo yayo futhi sibe nokuqonda okujulile kwendima nomgomo wentambo ye-pdo yobuhle bezokwelapha.
1. Iyini intambo ye-pdo yobuhle bezokwelapha?
Ubuhle bezokwelapha intambo ye-pdo, ngamagama alula, iwucingo olukhethekile olusetshenziswa emkhakheni wobuhle bezokwelapha. Ivamise ukwenziwa ngezinto ezimuncayo, njenge-PDO (i-polydioxanone), njll., enokuhambisana okuhle kwe-biocompatibility kanye nokuwohloka. Lezi zintambo zenzelwe ukuba zibe zincane kakhulu futhi zingangena kalula ezicutshini zesikhumba ngaphandle kokubangela ukuhlukumezeka okusobala.
2. Indima yobuhle bezokwelapha intambo ye-pdo
(1) Ukuqinisa nokuphakamisa
Ngokukhula, isikhumba kancane kancane silahlekelwa ukunwebeka futhi siyaxega futhi sinyakaze. Intambo yobuhle bezokwelapha i-pdo ingakwazi ukuphakamisa kahle izicubu zesikhumba ezixegayo futhi yenze ubuso bobuso buqine futhi bucace ngokungena esikhunjeni futhi bakhe isakhiwo sokusekela ezingxenyeni ezithile. Lo mphumela wokuphakamisa uwukuthi
ngokushesha, futhi njengoba ucingo lungena kancane kancane, izicubu zesikhumba zizokhiqiza i-collagen entsha ngaphansi kokuvuselela kwayo, ngaleyo ndlela ifinyelele umphumela wokuqinisa isikhathi eside.
(2) Khuthaza ukukhiqizwa kabusha kwe-collagen
Lapho intambo yobuhle bezokwelapha i-pdo ifakwe esikhumbeni, izogqugquzela izicubu zesikhumba ukuthi zikhiqize impendulo yokuzivikela komzimba njengomzimba wangaphandle. Le mpendulo yokuzivikela komzimba izokhuthaza amangqamuzana esikhumba ukuthi akhiphe i-collagen eyengeziwe nemicu yokunwebeka, ngaleyo ndlela athuthukise ukuthungwa kwesikhumba futhi asenze sibe bushelelezi futhi sintekenteke. Ukuvuselelwa kwe-collagen akukwazi nje ukuthuthukisa ukuqina nokuqina kwesikhumba, kodwa futhi kufiphale imigqa emihle nemibimbi, okwenza isikhumba sikhanye ngokukhazimula kobusha.
(3) Thuthukisa ikhwalithi yesikhumba
Ngaphezu kokuqinisa nokuphakamisa kanye nokuvuselela ukuvuselelwa kwe-collagen, intambo yobuhle bezokwelapha i-pdo ingabuye ithuthukise ikhwalithi yesikhumba ngokugqugquzela ukujikeleza kwegazi kanye nokujikeleza kwe-lymphatic. Lapho ucingo lwakha isakhiwo esifana nenethiwekhi esikhumbeni, singashukumisa ukwanda kwemithambo yegazi ezungezile kanye nemithambo ye-lymphatic, ngaleyo ndlela kusheshise ukugeleza kwegazi ne-lymph. Lokhu akusizi nje ukukhipha ubuthi kanye nemfucuza esikhumbeni, kodwa futhi kunikeza ukudla okunomsoco kanye nomoya-mpilo esikhumbeni, okwenza isikhumba sibe nempilo futhi sibe namandla.
3. Isifaniso empilweni
Ukuze uqonde kangcono indima ye-pdo thread, singayiqhathanisa nokusekelwa kwesihlahla. Lapho isihlahla sikhula sifinyelele ukuphakama okuthile, ukuze sigcine ukuzinza kwaso, kudingeka sakhe isisekelo esizungeze isiqu ukuze sisisekele. Ngokufanayo, lapho isikhumba sethu sixega futhi siwohloka, imicu ye-pdo yobuhle bezokwelapha ifana nama-stents angabonakali angasekela izicubu zesikhumba ezixegayo futhi abuyisele ukuqina nokunwebeka kwaso.
4. Izinyathelo zokuphepha
Yize imicu ye-pdo inezinzuzo eziningi, usadinga ukunaka amaphuzu alandelayo lapho uthola ukwelashwa okufanele:
· Khetha isikhungo sezokwelapha esivamile kanye nodokotela ozomhlinza;
· Qonda inqubo yokwelashwa kanye nezingozi ezingaba khona ngokuningiliziwe ngaphambi kokwelashwa;
• Naka ukunakekelwa kwesikhumba nokuvikelwa elangeni ngemva kokwelashwa;
· Landela iseluleko sikadokotela ukuze uhlolwe njalo futhi ulandelelwe.
5. Isiphetho
Njengendlela yobuhle ephephile nephumelelayo, imicu ye-PDO kancane kancane iba yinketho yabafuna ubuhle abaningi. Ngokuqonda isimiso sayo sokusebenza nezinyathelo zokuphepha, singabuka lobu buchwepheshe ngokunengqondo ngokwengeziwe futhi sifeze amaphupho ethu amahle ngaphansi kokuqondisa kodokotela abangochwepheshe. Ngethemba ukuthi le khophi yesayensi ethandwayo ingakusiza uqonde kangcono imicu ye-pdo yobuhle bezokwelapha futhi ikwenze uzethembe ngokwengeziwe futhi uzole endleleni eya ebuhleni.
