Suture ni iki?

Inanga ya Suture ikoreshwa cyane muguhuza ingirangingo zoroshye (urugero, imitsi, ligaments, na meniscus) kumagufwa kandi byabaye ibikoresho byingenzi mubuvuzi bwa siporo no mugihe cyo kubaga arthroscopique. Nkuko ikoreshwa rya suture ryiyongereye, ibyiza bitandukanye byihariye nibibazo byagaragaye. Nkigisubizo, ibyuma bya suture bihora bihinduka kugirango bibe byiza kandi neza. Muri ibi bidukikije bigenda bihinduka, ni ngombwa mubuvuzi kubaga gusobanukirwa ibintu byingenzi biranga inanga zihagije.

Gukoresha inanga ya suture byahinduye uburyo bwo kubaga amagufwa kuko bituma habaho gukosora byoroshye kandi neza neza ingirangingo zoroshye (urugero, imitsi na ligaments) kumagufwa haba kubaga no gufungura arthroscopique hafi yigitugu, inkokora, ukuboko, hamwe ningingo zo hepfo.) Kubaga ibitugu byahindutse cyane muburyo bwa tekiniki zikoreshwa kuva gusana kumugozi, kwangirika kwa shobora, gusana arthroscopique ukoresheje ibyuma bya suture.

Igikorwa cyibanze cya suture ni uguhuza ingirangingo ahabigenewe no gukomeza umwanya wacyo nta kugabanuka cyangwa guhagarika umutima bikabije kugeza gukira kwa physiologique birangiye. Icyuma cyiza cya suture cyoroshye kubyitwaramo, bikomeza imbaraga zihagije zo gukuramo, birinda gukuramo suture, kandi birashobora gukururwa bitavuyemo ingaruka iyo ari yo yose nkuko ibikoresho bishonga.) Ubwoko butandukanye bwa ankeri bwatejwe imbere, kandi ibishushanyo bya ankeri byahindutse mumyaka icumi ishize kugirango bigaragaze imbaraga zabyo mugukora neza.

Polyetheretherketone

Kuberako ibyuma bimwe na bimwe bishobora kwangirika vuba, iterambere ryikinyabuzima ryakurikiranwe. Iyo nkingi ya biostable-polyetheretherketone ( PEEK ) polymer - iboneka mugukoresha imyunyu ya bispenol)

PEEK iragenda ikoreshwa mubice bigize tribologiya kubera imikorere yayo myiza. PEEK Kubwibyo, ifite izindi porogaramu nyinshi mubuhanga nubuvuzi.) PEEK nayo itanga ibyiza, nkibishusho byiza nyuma yo kubagwa no gukosorwa neza, kandi ntakibazo kijyanye no kwangirika kwa polymer. Icyangombwa, ikibazo gikomeye hamwe na PEEK cyerekanwe ko ari osseointegration mbi. Muri rusange ariko, iterambere rya PEEK inanga ryatumye hafatwa ibikoresho bya biocomposite bishobora gushyigikira ingirabuzimafatizo ya osteoconductive.)

BIOCOMPOSITE SUTURE ANCHOR

Ibinyabuzima bya suture ya biocomposite bigizwe nibintu byombi bishobora kwangirika kandi bigahindura amagufwa ateza imbere bioceramic. Bioceramic ikoreshwa cyane ni beta-tricalcium fosifate (β-TCP); izindi zirimo hydroxyapatite, calcium sulfate, na calcium ya karubone.) TCP ikoreshwa cyane mububaga bwamagufwa kugirango yuzuze inenge yamagufwa kuko (1) ifite imyunyu ngugu isa niy'amagufwa yabantu, (2) macro-porosity na micro-porosity ni osteoconductive, kandi (3) ifite biocompatibilité kandi irwanya ubukanishi. Bitandukanye na β-TCP, hydroxyapatite ni imyunyu ngugu isanzwe ifitanye isano n'amagufwa kandi ntishobora kubangikanya cyane kubera ko isa n'ibigize imyunyu ngugu y'amenyo n'amagufwa y’inyamabere.) Muri rusange, hydroxyapatite ishingiye ku magufwa asimbuza amagufwa afatwa nk'ibidashoboka cyangwa afite igipimo cyo hasi cyane ugereranije na β-TCP (Ishusho 3)).

BYOSE-BYOROSHE BIKURIKIRA

Ubwoko bukomeye bwa suture (urugero, ibyuma na polymer) byakozweho ubushakashatsi bwimbitse kandi bigaragara ko bihagije mugukomeza imitwaro ya physiologique kumubiri woroshye kugeza kumagufwa. Mubisanzwe, ibyo byuma byubwoko bukomeye bikenera kubagwa ahantu hafite ibirenge byamagufwa (decortication, punching, cyangwa dring) bishobora gutera igufwa kubera ubunini bwigice.)

Byose byoroheje bya suture (ASAs) byakozwe kugirango bigabanye ingorane hamwe nigitero kijyanye no gukoresha ibyuma bikomeye. Izi ASA zigizwe na kimwe cyangwa byinshi ultra-high-molecular-uburemere bwa polyethylene (UHMWPE) -bikubiyemo suture.

Ubusanzwe ASA igizwe nintoki cyangwa kaseti ikozwe mubikoresho byo kudoda unyuzamo UHMWPE irimo suture. Ubu buryo bwo gukosora buratandukanye ugereranije na screw-ubwoko bwa suture. Iyo ASA yinjijwe mumagufwa hanyuma suture yibanze ikururwa, amaboko cyangwa kaseti bifatanyirizwa hamwe kugirango bigabanye amagufwa ya cortical arenga arema 'umupira ' ukora nk'inanga. Iremera inanga ya suture gushyirwa mumurongo ufite diameter ntoya (1-3 mm), bityo ikarinda amagufwa kandi ikanatanga hypothetike ituma amagufwa arinda cyane, ibyo bikaba bishobora kugirira akamaro cyane cyane kubera amagufwa make kuri glenoid rim cyangwa acetabulum. Na none, niyo habaho kunanirwa kwa ankeri, ibyangiritse bishobora kugabanuka kubera umubiri woroshye.)

Ubuyobozi buhebuje kuri PEEK Inanga: Ibyiza, Porogaramu, hamwe ninyungu

Niba ushaka ibikoresho bishobora gutanga imbaraga zisumba izindi, ubukana, hamwe n’imiti irwanya imiti, PEEK (polyetheretherketone) ni amahitamo meza. PEEK Muri iyi ngingo, tuzaganira PEEK inanga, imitungo yabo, porogaramu, nibyiza.

Niki PEEK Inanga?

PEEK PEEK nizifunga zakozwe { Bakunze gukoreshwa mubuvuzi, ikirere, ibinyabiziga, na peteroli na gaze, nibindi. PEEK inanga zizwiho ubushobozi bwo kwihanganira imitwaro myinshi, ihinduka ryubushyuhe, hamwe nibidukikije bikaze.

Ibyiza bya PEEK Inanga

PEEK inanga zifite imitungo myinshi ituma iruta ibindi bikoresho. Bimwe mubintu bizwi cyane bya PEEK inanga zirimo:

Imbaraga Zikomeye no Gukomera

PEEK inanga zifite imbaraga zingana kandi zikomeye, bigatuma biba byiza kubisabwa bisaba inanga ikomeye kandi yizewe. Barashobora kwihanganira imizigo myinshi ningaruka badasenyutse cyangwa ngo bahindure.

Kurwanya imiti

PEEK inanga irwanya cyane imiti myinshi, harimo aside, ibishingwe, hamwe n’umuti ukomoka ku buhinzi. Ibi bituma biba byiza mubisabwa aho biteganijwe guhura n’imiti ikaze.

Ubushyuhe bwumuriro

PEEK inanga zifite ubushyuhe buhebuje bwumuriro, hamwe nubushyuhe bwo hejuru bugera kuri 300 ° C nta gushonga cyangwa gutesha agaciro. Zirwanya kandi ubukonje bukonje, bigatuma biba byiza gukoreshwa muri progaramu ya cryogenic.

Ibinyabuzima

PEEK inanga ni biocompatable, bigatuma itekanwa kugirango ikoreshwe mubuvuzi n amenyo. Ntabwo kandi ari uburozi kandi butari kanseri, bigatuma bahitamo ibidukikije.

Porogaramu ya PEEK Inanga

PEEK inanga zifite uburyo butandukanye bwo gusaba, harimo:

Ubuvuzi n'amenyo

PEEK Ibikoresho byatewe mu magufa Biocompatibilité no kurwanya ruswa no kwambara bituma biba byiza gukoreshwa mumubiri wumuntu.

Ikirere

PEEK inanga zikoreshwa mu nganda zo mu kirere kubera imbaraga zazo nyinshi no guhangana n’imihindagurikire y’ubushyuhe n’imiti. Bikunze gukoreshwa muri moteri yindege, avionics, nibice bigize imiterere.

Porogaramu yimodoka

PEEK inanga zikoreshwa mu nganda z’imodoka kubera ko zirwanya kwambara, ihinduka ry’ubushyuhe, n’imiti. Bikunze gukoreshwa muri moteri, kohereza, hamwe na sisitemu ya lisansi.

Gukoresha Amavuta na Gazi

PEEK inanga zikoreshwa mu nganda za peteroli na gaze kubera guhangana n’umuvuduko mwinshi, ihindagurika ry’ubushyuhe, n’imiti. Bikunze gukoreshwa mubikoresho byo hasi, valve, na pompe.

Ibyiza bya PEEK Inanga

PEEK inanga zitanga inyungu nyinshi kurenza ibindi bikoresho, harimo:

Umucyo

PEEK inanga ziremereye ugereranije nibindi byuma, bigatuma biba byiza mubisabwa aho uburemere buteye impungenge.

Ikigereranyo Cyinshi-Kuri-Ibipimo

PEEK

Kurwanya ruswa

PEEK inanga zirwanya ruswa cyane, bigatuma zikoreshwa neza mubidukikije.

Kwambara Kurwanya

PEEK inanga zirwanya cyane kwambara, bigatuma biba byiza gukoreshwa mubisabwa aho gukuramo ari ikibazo.

Byoroshye Kumashini

PEEK inanga ziroroshye kumashini, bigatuma ihitamo ikiguzi kubikorwa byinshi.

Umwanzuro

PEEK inanga ni ibintu byinshi kandi byihuta-byihuta byihuta kumurongo mugari wa porogaramu. Hamwe nimiterere yabo idasanzwe, ikoreshwa, nibyiza, biragenda byamamara mubikorwa byinshi. Kuva mubuvuzi no kumenyo y amenyo kugeza mubyogajuru hamwe nibigize ibinyabiziga, PEEK inanga zitanga inanga zizewe kandi zikomeye hamwe nibintu byiza cyane bituma zitandukana nibindi bikoresho.
