Ezi ziindaba ezimnandi kwizigulane ze-hip!
Le yimbali yempumelelo kwintsimi yamalungu okwenziwa eTshayina!
Olu luhlaselo lohlaselo olwaphula ukulawulwa kobuchwephesha bangaphandle!
Kutshanje, kwiSibhedlele saseMzantsi seYunivesithi yezoNyango yaseMazantsi, uGqr Wang Jian, uSekela Mlawuli weSebe lezoNyango oluHlangeneyo kunye noNyango lwamathambo, wafaka isigulane esineminyaka engama-44 ubudala esine-spondylitis ye-ankylosing kunye ne-domestic all-ceramic artificial hip joint usebenzisa ubuchwepheshe obutsha. isisombululo, apho indebe ye-acetabular eprintiweyo ye-3D kunye ne-bone trabeculae yakhethwa kwicala le-acetabular kunye ne-tantalum yokuqala yasekhaya ehlanganiswe ne-femoral stem ye-femoral side.
Igama elithi "i-tantalum-coated femoral stem" libuchwephesha kangangokuba libe ngaphaya kwe-ken ye-layman ephakathi, kodwa abo basesimini baya kuqonda ubunkokeli bayo obukhethekileyo bobuchwepheshe.Itekhnoloji yokugquma iTantalum yalawulwa yiUnited States ngaphambili.Namhlanje, i-China iye yatyhoboza kobu buxhakaxhaka betekhnoloji kwaye yaba lilizwe lesibini emhlabeni elinokwenza i-tantalum coated femoral stem.
Utyando olwenziwa nguDkt Wang Jian, iSekela likaGqirha oyiNtloko liphumelele.Akukuphela nje ukuba indebe ye-acetabular ye-trabecular inikeze ugqirha ngokuzinza okuqinileyo kokuqala, kodwa i-tantalum-coated femoral stem, eyokuqala yohlobo lwayo e-China, nayo yabonisa ukungqubuzana okungenakulinganiswa kunye nokuzinza okuchasene nokujikeleza.Ukufakelwa kwesi sinqe sokwenziwa kwe-ceramic kulindeleke ukuba sihlale ubomi bonke.
Impumelelo yalo msebenzi ikwabhengeza ukuba obu buchwephesha bemeko yobugcisa kunye nesiqu sokuqala se-tantalum metal-coated femur e-China enamalungelo azimeleyo epropathi enomgangatho ophezulu wokuqonda ziye zaziswa ngempumelelo eklinikhi, eziya kunceda kakhulu izigulane kwaye zibe nethemba elingenamkhawulo. .
Le teknoloji yokwambathisa tantalum kunye patent ezizodwa No. ZL 2016 2 1197203.5 yoyiswa China yi LDK.Esi siqu se-femoral esisigxina sibonelela ngojongano oluhle kakhulu lwe-tantalum yesinyithi.Inomklamo we-wedge osicaba, ovumela ukugcinwa kwamathambo okwaneleyo kwaye iququzelele ukukhula kwethambo lethambo kwisakhiwo se-tantalum, eqinisekisa ukuzinza kwexesha elide.I-prosthesis ikhuselekile ngokwebhayoloji, ineempawu ezinamandla zoomatshini kunye nokuhambelana ne-biocompatibility engcono, ukumelana nokubola kunye neempawu zokulwa ne-antibacterial.
Phambili ekutshintsheni okudibeneyo, i-prosthesis "yeTrabecular Acetabular Cup + Tantalum Femoral Stem + Full Ceramic Wear Interface" yiprosthesis eyaziwa ngamazwe ngamazwe "igolide".Kuyaphawuleka ngokukodwa kuba ijongene neemfuno ezintathu eziphambili zezigulane ezincinci ezine-ankylosing spondylitis: ukusetyenziswa kwexesha elide, ukuzinza kokuqala kunye nokudibanisa ngokukhawuleza kwe-bone-prosthesis interface.
I-LDK's tantalum femoral stem (i-STH Stem) inomphezulu oguquliweyo wecoat eyilelwe ukuba rhabaxa kwaye inike uzinzo olukhulu xa kuthelekiswa nobuchwepheshe base-US.Ukongeza, isiqu luyilo lwemilo ekhoyo ngoku olulungele utyando olungephi, ngaloo ndlela kuncitshiswa ukulahleka kwethambo le-iatrogenic kunye nokwenza lula ukuchacha kwesigulana ngokukhawuleza.
Sidibanisa ubuchwephesha bamazwe ngamazwe, izakhono ezigqwesileyo zotyando kunye noluvo loxanduva lokunika sonke isigulana esitshintshwayo esidibeneyo amava agqibeleleyo.
Njengogqirha wezonyango, usekela mlawuli wezolawulo, usekela ugqirha oyintloko kunye nomphathi wesidanga senkosi, uWang Jian weSibhedlele saseMazantsi seYunivesithi yezoNyango yaseMazantsi ube ngowokuqala ukwenza utyando lokutshintshwa kwenyonga kunye ne-OCM kwindawo ethe tye e-China, ekhokela uphuhliso lolawulo lweperioperative olungenazintlungu kunye nokuvuselelwa ngokukhawuleza kuqhaqho oludibeneyo eMzantsi China, kwaye uye wafumana udumo lokubonelela izigulana ngezisombululo zamva nje kwintsimi yamathambo amaxesha amaninzi.
I-LDK yenze impumelelo engazange ibonwe ngaphambili kwitekhnoloji ye-tantalum yokwambathisa, ukwaphula imeko ekhoyo ngoku ye-monopoly eqhubekayo kule ntsimi ngamazwe angaphandle.Isiqu sokuqala sasekhaya se-tantalum femur, esikwayi-tantalum yokuqala egqunywe i-femur stem eyenzelwe utyando olungenabungozi kwihlabathi, ifakwe ngempumelelo kwizigulana.U-Wang Jian, usekela ugqirha oyintloko, uye waba ngumntu wokuqala ukusebenzisa le prosthesis ukwenzela utyando lokutshintshwa kwe-hip.Ibonisa ixesha le-tantalum ehlanganiswe ne-femur stem ngamalungelo azimeleyo epropathi yobukrelekrele e-China ifikile, kwaye ixesha elitsha lokudibanisa okwenziweyo e-China. ivulwe njalo.
