PEEK Nangula

Kodi anchoring suture ndi chiyani?

Nangula wa suture amagwiritsidwa ntchito kwambiri kulumikiza minofu yofewa (mwachitsanzo, ma tendon, ligaments, ndi meniscus) ku fupa ndipo zakhala zida zofunika kwambiri pamankhwala azamasewera komanso panthawi ya opaleshoni ya arthroscopic. Pamene kugwiritsiridwa ntchito kwa nangula kwa suture kukuchulukirachulukira, ubwino ndi zovuta zosiyanasiyana zakuthupi zanenedwa. Zotsatira zake, anangula a suture akusintha mosalekeza kuti akhale otetezeka komanso ogwira mtima. M'malo omwe akusintha nthawi zonse, ndikofunikira kuti dokotala amvetsetse zofunikira za nangula zomwe zilipo mokwanira.

Kugwiritsiridwa ntchito kwa anangula a suture kwasintha opaleshoni ya mafupa chifukwa kumapangitsa kuti minofu yofewa ikhale yosavuta komanso yogwira mtima (mwachitsanzo, tendons ndi ligaments) ku fupa pa opaleshoni yotseguka ndi ya arthroscopic kuzungulira phewa, chigongono, dzanja, ndi ziwalo zapansi.) Opaleshoni yapaphewa makamaka yasintha kwambiri mtundu wa njira zomwe zimagwiritsidwa ntchito pogwiritsa ntchito makina otsegula, zitsulo zotchinga ndi labrus. transosseous sutures, ndi zofunika kukonza arthroscopic pogwiritsa ntchito nangula wa suture.

Ntchito yayikulu ya nangula wa suture ndikuyika minofu pamalo oyenera ndikusunga malo ake popanda kumasula kapena kupsinjika kwambiri mpaka machiritso a physiologic akwaniritsidwa. Nangula yabwino ya suture ndi yosavuta kugwiritsira ntchito, imakhala ndi mphamvu zokwanira zokoka, imalepheretsa kuphulika kwa suture, ndipo imatha kuyamwa popanda kuchititsa kuti zinthu ziwonongeke.

Polyetherketone

Chifukwa chakuti anangula ena owonongeka amatha kuyamwa mwachangu kwambiri, kukonza ma nangula a biostable kunayambika. Nangula wotere wa biostable-polyetheretherketone ( PEEK ) polima-amapezeka mwa dialkylation ya mchere wa bisphenol)

PEEK ikugwiritsidwa ntchito kwambiri m'magawo a tribological chifukwa chakuchita bwino kwambiri. PEEK zida zidawonetsa mphamvu zambiri, zida zamakina amphamvu, zowoneka bwino komanso zosagwira kutentha, komanso kukana kwamankhwala komanso kwachilengedwe. Choncho, ili ndi ntchito zina zambiri mu engineering ndi mankhwala.) PEEK imaperekanso ubwino, monga kujambula bwino pambuyo pa opaleshoni ndi kukonza kokhazikika, ndipo palibe zovuta zokhudzana ndi kuwonongeka kwa polima. Chofunika kwambiri, vuto lalikulu ndi PEEK lasonyezedwa kuti silinagwirizane bwino ndi osseointegration. Komabe, kukula kwa PEEK nangula kwapangitsa kuti pakhale zopangira biocomposite zomwe zingathandize osteoconductive ingrowth.)

BIOCOMPOSITE SUTURE ANCHOR

Nangula wa biocomposite suture amapangidwa ndi zinthu zonse zomwe zimatha kuwonongeka ndi polima komanso fupa lomwe limalimbikitsa bioceramic. Bioceramic yomwe imagwiritsidwa ntchito kwambiri ndi beta-tricalcium phosphate (β-TCP); zina zimaphatikizapo hydroxyapatite, calcium sulfate, ndi calcium carbonate.) TCP imagwiritsidwa ntchito kwambiri pa opaleshoni ya mafupa kuti idzaze zofooka za mafupa chifukwa (1) ili ndi mchere wofanana ndi mafupa a munthu, (2) macro-porosity ndi micro-porosity ndi osteoconductive, ndipo (3) ali ndi biocompatibility yabwino kwambiri komanso kukana makina. Mosiyana ndi β-TCP, hydroxyapatite ndi mchere wachilengedwe womwe umakhala wogwirizana ndi mafupa ndipo umagwirizana kwambiri ndi biocompatible chifukwa ndi ofanana ndi chigawo cha mchere cha mano ndi mafupa a nyama zoyamwitsa.) Kawirikawiri, hydroxyapatite-based bone mmalo mwa mafupa amaonedwa kuti ndi osagwiritsidwa ntchito kapena ali ndi ziwopsezo zochepa kwambiri kuposa β-TCP (Fig).

ALL-SOFT SUTURE ANCHOR

Nangula zamtundu wokhazikika (mwachitsanzo, zitsulo ndi polima) zaphunziridwa mozama ndipo zapezeka kuti ndizokwanira kusunga katundu wa physiologic pa minofu yofewa kupita kumagulu a mafupa. Nthawi zambiri, anangula amtundu woterewa amafunikira kukonza maopaleshoni am'mbali mwa mafupa (kukongoletsa, kubowola, kapena kubowola) komwe kungayambitse mafupa chifukwa cha kuchuluka kwa chidutswacho.)

All-soft suture anchors (ASAs) adapangidwa kuti achepetse zovuta komanso zowononga zokhudzana ndi kugwiritsa ntchito anangula amtundu wolimba. Ma ASAwa amakhala ndi ma sutures omwe ali ndi polyethylene (UHMWPE) imodzi kapena zingapo.

Ma ASA nthawi zambiri amakhala ndi manja kapena tepi yopangidwa ndi suture yomwe imalukidwa ndi UHMWPE wokhala ndi suture. Makina okonzera awa amasiyana poyerekeza ndi anangula amtundu wa screw suture. Pamene ASA imalowetsedwa mu fupa ndipo suture yoyamba imakokedwa, mkono kapena tepiyo imadulidwa kuti ipanikizike ndi fupa la cortical lomwe limapanga 'mpira' yomwe imagwira ntchito ngati nangula. Zimalola kuti nangula wa suture aikidwe mumsewu wokhala ndi mainchesi ang'onoang'ono (1-3 mm), potero kusunga fupa ndi kuganiza mozama kuti mafupa asungidwe, zomwe zingakhale zopindulitsa kwambiri chifukwa cha kuchepa kwa mafupa pamphepete mwa glenoid kapena acetabulum. Ndiponso, ngakhale kulephera kwa nangula kunachitika, kuwonongeka kwa mafupa kungachepe chifukwa cha thupi lofewa la nangula.)

Ultimate Guide to PEEK Nangula: Katundu, Ntchito, ndi Ubwino

Ngati mukuyang'ana zinthu zomwe zingapereke mphamvu zapamwamba, zolimba, ndi kukana mankhwala, PEEK (polyetheretherketone) ndiye chisankho chabwino kwambiri. PEEK ndi polima yochita bwino kwambiri yomwe yadziwika bwino m'mafakitale ambiri chifukwa cha makina ake apamwamba, kuyanjana kwachilengedwe, komanso kukhazikika kwamafuta. M'nkhaniyi, tikambirana za PEEK nangula, katundu wawo, ntchito, ndi ubwino wake.

Kodi PEEK Nangula ndi chiyani?

PEEK anangula ndi zomangira zopangidwa ndi PEEK zinthu zomwe zimapangidwa kuti zizipereka zolimba komanso zodalirika pamapulogalamu osiyanasiyana. Amagwiritsidwa ntchito kwambiri m'mafakitale azachipatala, zakuthambo, zamagalimoto, ndi mafuta ndi gasi, pakati pa ena. PEEK anangula amadziwika ndi kuthekera kwawo kupirira katundu wambiri, kusintha kwa kutentha, komanso malo ovuta.

Katundu wa PEEK Nangula

PEEK anangula ali ndi zinthu zambiri zomwe zimawapangitsa kukhala apamwamba kuposa zida zina. Zina mwazodziwika bwino za nangula za PEEK ndi:
