Mu rwego rwo guhahamuka kwa maxillofacial no kwiyubaka, ubunini bwimiterere yamagufwa hamwe nuburyo bwo gupakira bishyira hejuru cyane kubikoresho byo gutunganya imbere. Muri ibyo, isahani ntoya yamagufa-nka Locking Maxillofacial Mini Straight Plate - yabaye igisubizo cyingenzi cyo guhagarika imvune mubice byoroshye byo mumaso.
Iyi ngingo irasesengura udushya twubuhanga muriisahani nto, kwibanda ku guhitamo ibikoresho, gushushanya intera, no gufunga imiterere kunoza imikorere yo kubaga no gutuza igihe kirekire.
Guhanga ibikoresho: Ubukuru bwa Titanium na Titanium Alloys
Guhitamo ibikoresho nibyingenzi mugushushanya sisitemu yo gutunganya amagufwa. Isahani ntoya igomba kugera kuburinganire bwiza bwa biocompatibilité, imbaraga za mashini, kurwanya umunaniro, hamwe na radiografiya. Titanium n'ibiyikomokaho byagaragaye nkibipimo bya zahabu muriki gice.
Ifunga rya Maxillofacial Mini Straight Plate i Shuangyang ikozwe muri titanium yo mu rwego rwo kwa muganga, ikomoka cyane cyane mu bikoresho bya titanium yo mu Budage ZAPP. Ibi bituma biocompatibilité nziza, ingano nziza-ingano, hamwe no kutagira amashusho make-inyungu nyamukuru mubizamini bya CT na MRI nyuma yibikorwa.
Urebye mubuhanga, titanium itanga inyungu nyinshi zingenzi:
Ibinyabuzima bisumba byose:
Titanium isanzwe ikora TiO₂ oxyde itajegajega hejuru yayo, itera osteointegration kandi ikarinda kwangirika mubinyabuzima.
Imbaraga nyinshi no Kurwanya Umunaniro:
Amavuta ya Titanium nka Ti-6Al-4V cyangwa Ti-6Al-7Nb yerekana imbaraga zidasanzwe kandi zihindagurika, bigatuma isahani yamagufa irwanya imbaraga zumukanishi mugihe cyo kwikinisha no gukira.
Guhuza amashusho:
Bitandukanye nicyuma cyangwa cobalt-chromium ibikoresho, titanium itanga ibihangano bike muri scan ya CT cyangwa MRI, bigafasha gusuzuma neza nyuma yibikorwa.
Byongeye kandi, isahani ntoya yerekana uburyo bwo kuvura budasanzwe, bwongera ubukana, kwambara, hamwe no kuramba muri rusange. Urebye kubijyanye na injeniyeri, anodisiyoneri inonosora microstructure ya oxyde, itezimbere kwihanganira umunaniro no kurwanya ruswa.
Mugihe titanium imaze gushingwa neza, haracyakurikiranwa optimizasiyo-cyane cyane mugutunganya microstructure, kugenzura imihangayiko isigaye, no guhindura ubuso-kugirango irusheho kwagura igihe kirekire no kugabanya irekurwa ryicyuma mugihe runaka.
Umwanya wa Hole na Geometrike Igishushanyo: Kuringaniza Ihamye na Anatomy
Uburinganire bwa geometrike isahani ntoya - harimo ubunini bwayo, intera y'umwobo, n'uburebure - bigira uruhare runini mubikorwa byayo bya mashini ndetse no kubaga imiterere yo kubaga.
Gufunga Maxillofacial Mini Straight Plate igaragaramo ibishushanyo byinshi, harimo umwobo 6 (mm 35), umwobo 8 (47 mm), 12-umwobo (71 mm), na 16-mwobo (95 mm), byose bifite uburebure busanzwe bwa mm 1,4. Ihindagurika ryemerera abaganga guhitamo iboneza rikwiye hashingiwe ku bwoko bwavunitse, imiterere yamagufwa, nibisabwa gukosorwa.
Urebye muburyo bwa injeniyeri, intera y'umwobo (intera iri hagati ya santere ya screw) igira ingaruka zitaziguye:
Ikwirakwizwa rya Stress:
Umwanya ukabije urashobora kuganisha ku kunama cyangwa umunaniro mugihe cyo gupakira imikorere, mugihe intera ndende cyane ishobora kugabanya igice cyamagufwa kandi bikongera ibyago byo gukuramo imigozi. Umwanya mwiza uteganijwe kwimura umutwaro umwe hagati yamagufwa na sisitemu yo gukosora.
Amagufa - Imigaragarire:
Umwanya ukwiye uremeza ko buri cyuma kigira uruhare runini mu kwikorera imitwaro nta kubyara impagarara zishobora kwihutisha kunanirwa.
Guhuza n'imihindagurikire y'ikirere:
Isahani igomba guhuza neza nubuso bwamagufwa, cyane cyane muburyo bugoramye bwakarere ka maxillofacial. Umuyoboro wa geometrie hamwe nintera byateguwe neza kugirango byemere guhindagurika byoroshye mugihe wirinze kwivanga hamwe nuburyo bwa anatomique.
Isesengura ryibintu bitagira ingano (FEA) kubisahani bisa namagufa byagaragaje ko intera itanoze neza ishobora kwongera imbaraga za von Mises ihangayikishije imbaraga ziva kuri titanium, bikagabanya ubuzima bwumunaniro. Kubwibyo, intera itomoye hamwe nu mwobo wa geometrike ihamye nibyingenzi byingenzi byubuhanga mubikorwa bya plaque.
Gufunga Mikoranike Itezimbere: Kuva Passive Fixation to Stable Stabilite
Isahani gakondo idafunga yishingikiriza ku guterana hagati yisahani hamwe nubuso bwamagufwa kugirango bihamye. Nubwo bimeze bityo ariko, muburyo bugaragara kandi butangaje bwibidukikije byo mumaso, ubu bwoko bwo gukosora burashobora guhinduka cyangwa kunyerera.
Gufunga mini ya kijyambere-nkibiri muri sisitemu yo gufunga Maxillofacial-ihuza uburyo bwo gufunga imashini hagati yumutwe wa plaque hamwe nisahani, bigakora imiterere imwe, ihuriweho. Ubu bushya bugaragaza intambwe ikomeye mu gutera imbere no gutuza.
Uburyo bwo gufunga bukoreshwa muri Locking Maxillofacial Mini Straight Plate ibiranga:
Tekinoroji yo gufunga ikora neza ituma abantu bakora cyane.
Gukoresha inshuro ebyiri gushushanya, bihujwe no gufunga no kudafunga imigozi, bitanga ihinduka ryinshi mugihe cyo kubagwa.
Ibyiza byubwubatsi bwa sisitemu yo gufunga harimo:
Kongera imbaraga no gushikama:
Imigozi ifunze ya plaque-plaque ikora nkimbere yimbere-inguni yubaka, kunoza ikwirakwizwa ryumutwaro no kugabanya micromotion kumwanya wavunitse.
Kugabanya amagufwa:
Kubera ko isahani itagiterwa no guterana hejuru yamagufwa, irinda kwikanyiza cyane kuri periosteum, kurinda amaraso no guteza imbere amagufwa byihuse.
Kunanirwa kunanirwa kunanirwa:
Mugukumira micro-kunyerera hagati yumutwe wa screw nu mwobo wa plaque, interineti ifunga igabanya imihangayiko yimitsi kandi ikongerera ubuzima bwa serivisi.
Iterambere risaba kwihanganira gutunganya neza, cyane cyane muguhuza no gutondekanya imigozi ya plaque. Gukora neza birerekana ubwubatsi bwa sisitemu igezweho.
Inzira zizaza: Kugana Ubwenge Bwinshi na Sisitemu Yihariye yo Gukosora
Igisekuru kizaza cyibikoresho byo gukosora bigenda byerekeza kumikorere yo hejuru, kwimenyekanisha gukomeye, hamwe no kongera ibisubizo byibinyabuzima. Udushya dushya turimo:
Amavuta mashya ya Titanium:
Gutezimbere β -cyiciro na Ti-Mo-Fe ibinyobwa bitanga imbaraga nyinshi hamwe na moderi yo hasi ya elastike yo hasi, kugabanya gukingira no kunoza imihindagurikire yigihe kirekire.
Icyapa cya 3D cyacapwe:
Inganda ziyongera zituma abaganga bashushanya amasahani yihariye y’abarwayi ahuye neza n’amagufwa, kugabanya kunama hagati yimikorere no guhitamo kwimura imitwaro.
Imikorere ya Surface:
Harashakishwa uburyo nka nano-texturing, antimicrobial coatings, cyangwa bioactive surface yo kuvura kugirango byihute osseointegration no kugabanya ingaruka zandura.
Gukoresha Igishushanyo Cyiza:
Icyitegererezo cya Element Modeling (FEM) kirimo gukoreshwa muburyo bwiza bwa geometrike, uburebure bwa plaque, hamwe no kugabanuka, bigatuma igabanywa rimwe hamwe nubuzima bwumunaniro.
Umwanzuro
Kuva guhitamo ibikoresho no gutandukanya umwobo kugeza uburyo bwo gufunga imashini, ibyuma bigezweho bya magufa ya kijyambere yo kubaga maxillofacial bikubiyemo guhuza byimazeyo ibikenerwa mu mavuriro no guhanga udushya.
Gufunga Maxillofacial Mini Igororotse
irerekana iterambere ryayo hamwe nubwubatsi bwa titanium yo mu rwego rwubuvuzi, hejuru ya anodize, geometrie itomoye, hamwe nigishushanyo mbonera cyo gufunga - guha abaganga kubisubizo byizewe, bihuza, kandi bikoreshwa muburyo bwa biomehanike.
Mugihe siyanse yibikoresho hamwe nubusobanuro bwuzuye bikomeje kugenda bitera imbere, igisekuru kizaza cya plaque yamagufa azazana imbaraga nyinshi, guhuza anatomique, hamwe nibikorwa bya biologiya, bifasha kubaga kubaga kugera kubuzima bwihuse no kunoza umusaruro mukwiyubaka kwa maxillofacial.
