Kubathengi abafuna ii-MOQ eziphantsi kunye neentlobo eziphezulu zeemveliso, ababoneleli be-Multispecialty Suppliers banikezela nge-MOQ ephantsi yokwenza ngokwezifiso, izisombululo ze-mini-to-end logistics, kunye nokuthengwa kweentlobo ezininzi, ezixhaswa lishishini labo elityebileyo kunye namava eenkonzo kunye nokuqonda okuqinileyo kweendlela zemveliso ezivelayo.
I.Yintoni ithambo lokwenziwa endaweni?
I-Synthetic bone substitutes zizinto ezithatha indawo yethambo eziveliswa ngokwenziwa kokwenziwa okanye iindlela zekhemikhali kwaye zisetyenziselwa ukulungisa iziphene zamathambo. Izinto ezingundoqo ziquka i-hydroxyapatite, i-β-tricalcium phosphate, kunye ne-polylactic acid, kwaye inezi mpawu zilandelayo:
Iintlobo zezinto eziphathekayo
Izinto eziphathekayo, ezifana ne-hydroxyapatite (efanayo ekubunjweni kwethambo lomntu) kunye ne-β-tricalcium phosphate, inika izakhiwo ezizinzileyo kunye ne-biocompatibility efanelekileyo.
Izinto zepolymer, ezifana ne-polylactic acid kunye ne-polyethylene, ziyakwazi ukubola kwaye zifakwe ngokuthe ngcembe emzimbeni, zisusa isidingo sokususwa kotyando lwesibini.
Izicelo zeklinikhi
Ngokuqhelekileyo zisetyenziselwa ukugcwalisa iziphene zamathambo okanye ukubonelela ngenkxaso yesakhiwo, njengomgubo wethambo owenziweyo kwi-alveolar bone utyando lokwandisa. Ezi zixhobo kufuneka zikhethwe ngokusekelwe kwiimeko ezithile zesigulane. Umzekelo:
Ukufakelwa kwamazinyo: Izinto ezifana ne-hydroxyapatite zihlala zisetyenziselwa ukuphucula ukuzinza kwethambo le-alveolar.
Ukulungiswa kwe-fracture: Iziphene zizaliswe nge-scaffolds zetsimbi okanye i-bioceramics.
Izinto eziluncedo nezingeloncedo
Izinto eziluncedo ziquka inkqubo yokulungiselela ukulawulwa kunye nokupheliswa kwesidingo sezinto ezongezelelweyo. Izinto ezingeloncedo ziquka ubuthathaka bebhayoloji kunye nesidingo sokudityaniswa nezinye izinto (ezifana nethambo le-autologous) ukomeleza ukusebenza kakuhle.
II.Ikhona uqhaqho-fakelo lwamathambo?
Utyando lwethambo lunokwenzeka. Ukutshintshwa kwethambo yindlela eqhelekileyo yotyando kwiyeza, ngokuyinhloko isetyenziselwa ukulungisa iziphene zamathambo ezibangelwa yintlungu, ukusuleleka, izicubu, okanye iziphene zokuzalwa, kunye nokunceda ukubuyisela ukusebenza kwamathambo. Imithombo yethambo yokutshintshwa ibandakanya ithambo elizenzekelayo (elivela kwamanye amalungu omzimba wesigulane), ithambo le-allogeneic (ithambo elinikezelweyo), kunye nezixhobo zethambo ezenziweyo. Ukhetho oluthile luxhomekeke kwimeko yesigulane.
I. Iintlobo zoTshintsho lwethambo
1. I-Autologous Bone Transplantation
Umgaqo: Ithambo livunwa kumathambo esigulane esingenabunzima (njenge-ilium okanye i-fibula) kwaye ifakwe kwindawo yesiphene.
Izinto eziluncedo: Akukho ukwaliwa, izinga eliphezulu lokuphilisa.
Ukungalungi: Isiza somnikeli sinokuba buhlungu okanye sichaphazeleke, kwaye isitokhwe samathambo silinganiselwe.
2. I-Allogeneic Bone Transplantation
UmGaqo: Ithishu yethambo enikelwe (i-sterilized kunye ne-deimmunized) isetyenziswa.
Isicelo: Iziphene ezinkulu zamathambo okanye ithambo le-autologous elinganelanga.
Imingcipheko: Ukulahlwa okunokwenzeka okanye usulelo lwezifo (kunqabile kakhulu).
3. IiMpahla zamathambo ezenziweyo
Iintlobo zezinto eziphathekayo: I-Hydroxyapatite, i-bioceramics, njl.
II. Ukusetyenziswa koTshintsho lweBone
Ukulungiswa komothuko: Umzekelo, ukuqhekeka okukhulu okukhokelela kwiziphene zamathambo ezingakwazi ukuziphilisa ngokwazo.
I-Bone tumor resection: Ukuzaliswa kwethambo emva kokutshatyalaliswa kwethumba.
Ukudityaniswa komqolo: Ukuphucula ukuzinza kwamathambo emva kotyando lwe-lumbar spine.
Ukulungiswa kokukhubazeka kokuzalwa: Ngokomzekelo, i-pseudarthrosis ye-congenital tibial.
Ixesha lokuposa: Sep-25-2025
