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 ingirabuzimafatizo zoroheje (urugero, imitsi na ligaments) kumagufwa haba kubaga no gufungura arthroscopique kubagwa ku rutugu, inkokora, ukuboko, hamwe ningingo zo hepfo.) Kubaga ibitugu byumwihariko byahindutse muburyo bwubuhanga bwakoreshwaga mu gusana ibyuma bya rotate, shobora, hamwe na laboratoire. gusana arthroscopique ukoresheje ibyuma bya suture.

Igikorwa cyibanze cya suture ni uguhuza ingirangingo ahabigenewe no gukomeza umwanya wacyo nta kugabanuka cyangwa guhagarika umutima kugeza igihe 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 mbonera byahindutse mugihe cyimyaka icumi kugirango bigaragaze neza 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 bya tribologiya kubera imikorere yayo myiza. Ibikoresho bya PEEK byerekanaga imbaraga nyinshi, ubukanishi bukomeye, kwambara neza no kurwanya ubushyuhe, hamwe n’imiti myiza n’ibinyabuzima. 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 na PEEK cyerekanwe ko ari osseointegration mbi. Muri rusange ariko, iterambere rya ankeri ya PEEK ryatumye hafatwa ibikoresho biocomposite ishobora 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 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 hamwe no kurwanya imashini. Bitandukanye na β-TCP, hydroxyapatite ni imyunyu ngugu isanzwe ifitanye isano n'amagufwa kandi ntishobora kubangikanya cyane kubera ko isa na minerval igizwe n'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 byagaragaye ko bihagije mugukomeza imitwaro ya physiologique kumubiri woroshye kugeza kumagufwa. Mubisanzwe, ibyo byuma byubwoko bukomeye bikenera gutegurwa kubagwa byikirenge (decortication, punching, cyangwa dring) bishobora gutera amagufwa kubera ubwinshi 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 kurema 'umupira ' ukora nk'inanga. Iremera inanga ya suture gushyirwa mumurongo ufite diameter ntoya (mm 1-3), bityo ikabika amagufwa kandi ikanatanga hypothetike ituma amagufwa menshi abungabungwa, bishobora kugirira akamaro cyane cyane kubera amagufwa make kuri glenoid rim cyangwa acetabulum. Na none, niyo byananirana inanga, ibyangiritse bishobora kugabanuka kubera umubiri woroshye.)

Ubuyobozi buhebuje kuri PEEK Anchors: Ibyiza, Porogaramu, nibyiza

Niba ushaka ibikoresho bishobora gutanga imbaraga zisumba izindi, gukomera, hamwe no kurwanya imiti, PEEK (polyetheretherketone) nuguhitamo neza. PEEK ni polymer ikora cyane yamenyekanye cyane munganda nyinshi kubera imiterere yubukorikori idasanzwe, ibinyabuzima, hamwe nubushyuhe bwumuriro. Muri iyi ngingo, tuzaganira ku byuma bya PEEK, imiterere yabyo, porogaramu, nibyiza.

PEEK Anchors ni iki?

PEEK inanga ni ibifunga bikozwe mubikoresho bya PEEK byashizweho kugirango bitange inanga ikomeye kandi yizewe mubikorwa bitandukanye. Bakunze gukoreshwa mubuvuzi, ikirere, ibinyabiziga, na peteroli na gaze, nibindi. PEEK inanga izwiho ubushobozi bwo kwihanganira imitwaro myinshi, ihinduka ryubushyuhe, hamwe nibidukikije bikaze.

Ibyiza bya PEEK

PEEK inanga ifite 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 mubikorwa bisaba inanga ikomeye kandi yizewe. Barashobora kwihanganira imizigo myinshi ningaruka badasenyutse cyangwa ngo bahindure.

Kurwanya imiti

PEEK inanga irwanya cyane imiti myinshi, harimo acide, base, hamwe na solge organic. Ibi bituma biba byiza mubisabwa aho biteganijwe guhura n’imiti ikaze.

Ubushyuhe bwumuriro

PEEK inanga zifite ubushyuhe buhebuje, 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, ituma itekanwa kugirango ikoreshwe mubuvuzi n amenyo. Ntabwo kandi ari uburozi kandi butari kanseri, bigatuma bahitamo ibidukikije.

Porogaramu ya PEEK Anchors

PEEK inanga ifite intera nini ya porogaramu, harimo:

Ubuvuzi n'amenyo

PEEK inanga zikoreshwa muburyo bwo kuvura no kuvura amenyo, nko gutera amagufwa, gutera amenyo, no gutera umugongo. 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 bitewe no kurwanya 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, hamwe n’imiti. Bikunze gukoreshwa mubikoresho byo hasi, valve, na pompe.

Ibyiza bya Anchors ya PEEK

PEEK inanga zitanga inyungu nyinshi kurenza ibindi bikoresho, harimo:

Umucyo

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

Ikigereranyo Cyinshi-Kuri-Ibipimo

PEEK inanga ifite imbaraga nyinshi-z-uburemere, bigatuma iba nziza kubisabwa aho imbaraga nyinshi zisabwa ariko uburemere bugomba kubikwa byibuze.

Kurwanya ruswa

PEEK inanga irwanya cyane kwangirika, bigatuma iba nziza yo gukoresha ahantu habi.

Kwambara Kurwanya

PEEK inanga irwanya cyane kwambara, bigatuma iba nziza yo gukoreshwa mubisabwa aho abrasion iteye impungenge.

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 nibigize amamodoka, inanga ya PEEK itanga inanga yizewe kandi ikomeye ifite imitungo isumba iyindi ituma bagaragara mubindi bikoresho.
