PEEK heleuma

He aha ka humuhumu heleuma?

Hoʻohana nui ʻia nā heleuma suture no ka hoʻopili ʻana i nā ʻiʻo palupalu (e laʻa, nā tendons, ligaments, meniscus) i ka iwi a ua lilo i mau mea pono i ka lāʻau lapaʻau haʻuki a i ka wā o ke kaʻina arthroscopic. E like me ka hoʻohana ʻana i nā heleuma suture, ua hōʻike ʻia nā mea pono a me nā pilikia. ʻO ka hopena, ke hoʻololi mau nei nā heleuma suture e lilo i mea palekana a ʻoi aku ka maikaʻi. I loko o kēia kaiapuni e loli mau nei, he mea pono i ke kauka lapaʻau ke hoʻomaopopo pono i nā hiʻohiʻona nui o nā heleuma e kū nei.

ʻO ka hoʻohana ʻana i nā heleuma suture ua hoʻololi i ke kaʻina orthopedic no ka mea e hiki ai ke hoʻopaʻa maʻalahi a maikaʻi hoʻi o nā ʻiʻo palupalu (e laʻa, nā tendons a me nā ligaments) i ka iwi ma ka wehe ʻana a me ke ʻoki arthroscopic a puni ka poʻohiwi, kuʻekuʻe lima, a me nā ami o lalo.) nā humuhumu, a me nā mea koʻikoʻi no ka hoʻoponopono arthroscopic me ka hoʻohana ʻana i nā heleuma suture.

ʻO ka hana mua o ka heleuma suture e hoʻopili i ka ʻiʻo ma ka pūnaewele kūpono a mālama i kona kūlana me ka ʻole o ka wehe ʻana a i ʻole ka ʻeha nui a hiki i ka hoʻōla ʻana o ka physiologic. He mea maʻalahi ka heleuma humuhumu, mālama i ka ikaika huki, pale i ka abrasion suture, a hiki ke komo me ka hopena ʻole i ka hoʻoheheʻe ʻana o ka mea.)

Polyetherketone

Ma muli o ka hikiwawe loa o kekahi mau heleuma biodegradable, ua alualu ʻia ka hoʻomohala ʻana o nā heleuma biostable. Loaʻa ia ʻano heleuma biostable—he polyetherketone ( PEEK ) polymer—ma ka dialkylation o nā paʻakai bisphenol )

Ke hoʻohana nui ʻia nei PEEK i nā ʻāpana tribological ma muli o kāna hana maikaʻi loa. PEEK nā mea i hōʻike i ka ikaika kiʻekiʻe, nā waiwai mekini ikaika, ka ʻaʻahu maikaʻi a me ke kūpaʻa wela, a me ke kūpaʻa maikaʻi loa o ke kemika a me ke olaola. No laila, nui nā mea hoʻohana ʻē aʻe i ka ʻenekinia a me ka lāʻau lapaʻau.) Hāʻawi pū ʻo PEEK i nā mea maikaʻi, e like me ke kiʻi postoperative maikaʻi a me ka hoʻoponopono paʻa, ʻaʻohe pilikia e pili ana i ka degradation polymer. ʻO ka mea nui, ua hōʻike ʻia ka pilikia nui me PEEK ʻaʻole maikaʻi ka osseointegration. ʻO ka holoʻokoʻa naʻe, ʻo ka hoʻomohala ʻana o PEEK heleuma ua alakaʻi i ka hoʻohana ʻana i nā mea biocomposite e kākoʻo i ka osteoconductive ingrowth.)

BIOCOMPOSITE SUTURE ANCHOR

Hoʻokumu ʻia nā heleuma suture Biocomposite me kahi mea polymer biodegradable a me kahi mea bioceramic e hoʻoulu ai i ka iwi. ʻO ka bioceramic i hoʻohana pinepine ʻia he beta-tricalcium phosphate (β-TCP); ʻO nā mea ʻē aʻe he hydroxyapatite, calcium sulfate, a me ka calcium carbonate.) Hoʻohana nui ʻia ʻo TCP i ke kaʻina orthopedic no ka hoʻopiha ʻana i nā hemahema o ka iwi no ka mea (1) loaʻa iā ia kahi ʻano mineral e like me ka iwi kanaka, (2) ʻo kona macro-porosity a me ka micro-porosity he osteoconductive, a (3) maikaʻi loa kona biocompatibility a me ka mechanical resistance. ʻAʻole like me ka β-TCP, hydroxyapatite he mea mineral maoli me ka pili i nā iwi a he biocompatible loa ia no ka mea ua like ia me kahi mea mineral o nā niho a me nā iwi o nā mammals.

ANCHOR SUTURE SOFT

Ua aʻo nui ʻia nā heleuma suture ʻano paʻa (e laʻa, metala a me ka polymer) a ua ʻike ʻia ua lawa no ka mālama ʻana i nā ukana physiologic ma nā ʻiʻo palupalu a me nā hui iwi. ʻO ka mea maʻamau, pono kēia mau heleuma ʻano paʻa i ka hoʻomākaukau ʻana i ke kahua o ke kapuaʻi iwi (decortication, kuʻi, a wili ʻana paha) i hiki ke nalowale ka iwi ma muli o ka nui o ka ʻāpana kumu.)

Hoʻokumu ʻia nā heleuma suture palupalu āpau (ASAs) e hōʻemi i nā pilikia a me ka invasiveness e pili ana i ka hoʻohana ʻana i nā heleuma ʻano paʻa. Aia kēia mau ASA i hoʻokahi a ʻoi aʻe paha ka polyethylene ultra-high-molecular-weight polyethylene (UHMWPE).

ʻO ka ASA ka mea maʻamau i kahi lima a i ʻole lipine i hana ʻia me nā mea suture kahi i ulana ʻia ai ka suture i loko o ka UHMWPE. He ʻokoʻa kēia ʻano hoʻoponopono i ka hoʻohālikelike ʻia me nā heleuma suture type screw. Ke hoʻokomo ʻia ka ASA i loko o ka iwi a huki ʻia ka humuhumu mua, hoʻopaʻa ʻia ka lima a i ʻole ka lipine i mea e hoʻopaʻa ai i ka iwi cortical ma luna aʻe e hana ana i 'pōpopo' e hana ma ke ʻano he heleuma. Hiki iā ia ke hoʻokomo i ka heleuma suture i loko o kahi tunnel me ka liʻiliʻi o ke anawaena (1-3 mm), no laila e mālama ai i ka iwi a me ka hypothetically e ʻae ai i ka mālama ʻana i ka iwi, a he mea maikaʻi paha ia ma muli o ka palena o ka iwi iwi ma ka glenoid rim a i ʻole acetabulum. Eia kekahi, ʻoiai inā hiki ʻole ka heleuma, hiki ke hōʻemi ʻia ka pōʻino hui ma muli o ke kino heleuma palupalu.)

ʻO ke alakaʻi hope loa i PEEK nā heleuma: nā waiwai, nā noi, a me nā pono

Inā ʻoe e ʻimi nei i kahi mea hiki ke hāʻawi i ka ikaika ʻoi aku ka ikaika, ka paʻakikī, a me ke kūpaʻa kemika, PEEK (polyetheretherketone) ke koho kūpono loa. ʻO PEEK ka polymer hana kiʻekiʻe i kaulana i nā ʻoihana he nui ma muli o kona mau ʻano mīkini koʻikoʻi, biocompatibility, a me ka paʻa wela. Ma kēia ʻatikala, e kūkākūkā mākou i nā heleuma PEEK , ko lākou mau waiwai, nā noi, a me nā pono.

He aha nā PEEK heleuma?

PEEK nā heleuma he mau mea paʻa i hana ʻia me PEEK mea i hoʻolālā ʻia no ka hāʻawi ʻana i ka heleuma ikaika a hilinaʻi hoʻi i nā hana like ʻole. Hoʻohana pinepine ʻia lākou i ka lāʻau lapaʻau, aerospace, automotive, a me nā ʻoihana ʻaila a me nā kinoea, a me nā mea ʻē aʻe. ʻIke ʻia nā heleuma PEEK no ko lākou hiki ke kū i nā ukana kiʻekiʻe, hoʻololi i ka mahana, a me nā wahi ʻino.

Pono o PEEK heleuma

PEEK nā heleuma he nui nā waiwai i ʻoi aku ka maikaʻi ma mua o nā mea ʻē aʻe. ʻO kekahi o nā waiwai kaulana loa o PEEK heleuma:

Ka ikaika kiʻekiʻe a me ka paʻakikī

PEEK nā heleuma he kiʻekiʻe ka ikaika a me ka paʻakikī, no laila kūpono lākou no nā noi e koi ana i ka heleuma ikaika a hilinaʻi. Hiki iā lākou ke pale aku i nā ukana kiʻekiʻe a me ka hopena me ka ʻole o ka haki ʻana a i ʻole deformation.

Palekana Kemika

PEEK paʻa loa nā heleuma i nā kemika he nui, me nā waikawa, nā kumu, a me nā mea hoʻoheheʻe organik. ʻO kēia ka mea kūpono iā lākou no nā noi kahi e manaʻo ʻia ai ka ʻike ʻana i nā kemika paʻakikī.

Paʻa wela

PEEK mau heleuma maikaʻi loa ka wela, kū i nā wela kiʻekiʻe a hiki i 300°C me ka hoʻoheheʻe ʻole ʻana a me ka hoʻohaʻahaʻa ʻole. Kūleʻa pū lākou i nā mahana anuanu, e hoʻolilo iā lākou i mea kūpono no ka hoʻohana ʻana i nā noi cryogenic.

Biocompatibility

PEEK nā heleuma he biocompatible, no laila palekana no ka hoʻohana ʻana i nā lāʻau lapaʻau a me nā noi niho. He mea ʻawaʻawa ʻole lākou a ʻaʻohe carcinogenic, e hoʻolilo iā lākou i kahi koho pili kaiapuni.

Noi o PEEK heleuma

PEEK nā heleuma he ākea ka hoʻohana ʻana, me:

Lapaau Lapaau a me Niho

Hoʻohana mau ʻia nā heleuma PEEK i nā lāʻau lapaʻau a me nā noi niho, e like me Nā mea hoʻokomo orthopedic , nā mea hoʻopaʻa niho, a me nā hoʻokomo ʻana i ke kuamoʻo. ʻO kā lākou biocompatibility a me ke kūpaʻa ʻana i ka corrosion a me ka ʻaʻahu e kūpono iā lākou no ka hoʻohana ʻana i ke kino kanaka.

Nā polokalamu Aerospace

Hoʻohana ʻia nā heleuma PEEK i ka ʻoihana aerospace ma muli o ko lākou ikaika kiʻekiʻe a me ke kūpaʻa ʻana i nā hoʻololi wela a me nā kemika. Hoʻohana pinepine ʻia lākou i nā ʻenekini mokulele, nā avionics, a me nā mea hana.

Noi Kaa

Hoʻohana ʻia nā heleuma PEEK i ka ʻoihana kaʻa ma muli o ko lākou kūʻē ʻana i ka ʻaʻahu, hoʻololi i ka mahana, a me nā kemika. Hoʻohana pinepine ʻia lākou i nā ʻenekini, nā hoʻoili, a me nā ʻōnaehana wahie.

Na Aila a me Gas

Hoʻohana ʻia nā heleuma PEEK i ka ʻoihana ʻaila a me ka ʻea ma muli o ko lākou kūpaʻa ʻana i ke kaomi kiʻekiʻe, hoʻololi i ka mahana, a me nā kemika. Hoʻohana pinepine ʻia lākou i nā mea hana downhole, valves, a me nā pamu.

Pono o PEEK heleuma

Hāʻawi nā heleuma PEEK i nā pono he nui ma mua o nā mea ʻē aʻe, e like me:

Māmā

Maʻalahi nā heleuma PEEK e hoʻohālikelike ʻia me nā metala ʻē aʻe, no laila kūpono ia no nā noi e pili ana i ke kaumaha.

Kiekie ikaika-a-kaumaha ratio

PEEK nā heleuma he kiʻekiʻe ka ikaika-a-kaumaha ratio, no laila kūpono ia no nā noi i koi ʻia ka ikaika kiʻekiʻe akā pono e mālama ʻia ke kaumaha i ka liʻiliʻi.

Pale ʻino

PEEK paʻa loa nā heleuma i ka ʻinoʻino, no laila kūpono ia no ka hoʻohana ʻana i nā wahi ʻino.

ʻAʻahu Kūʻē

PEEK paʻa loa nā heleuma i ka ʻaʻahu ʻana, no laila kūpono ia no ka hoʻohana ʻana i nā noi kahi e pilikia ai ka abrasion.

Māmā i ka Mīkini

PEEK maʻalahi nā heleuma i ka mīkini, e hoʻolilo iā lākou i koho kumu kūʻai no nā noi he nui.

Ka hopena

PEEK nā heleuma he koho hoʻopaʻa paʻa i ka hana kiʻekiʻe no ka nui o nā noi. Me kā lākou mau waiwai kūʻokoʻa, nā noi, a me nā pōmaikaʻi, ke ulu nui nei lākou i nā ʻoihana he nui. Mai nā lāʻau lapaʻau a me nā niho implants a i ka aerospace a me nā ʻāpana kaʻa, PEEK nā heleuma e hāʻawi i ka hilinaʻi a me ka ikaika o ka heleuma me nā waiwai maikaʻi e kū ai lākou mai nā mea ʻē aʻe.
