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 ʻoki 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 nui 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 haʻalulu 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 hoʻopaʻa ʻia me ka ʻole o ka hopena i ka hemo 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. ʻO kēlā heleuma biostable—he polyetherketone (PEEK) polymer—ua loaʻa ma ka dialkylation o nā paʻakai bisphenol)

Hoʻohana nui ʻia ka PEEK i nā ʻāpana tribological ma muli o kāna hana maikaʻi loa. Ua hōʻike nā mea PEEK i ka ikaika kiʻekiʻe, nā waiwai mechanical ikaika, ka ʻaʻahu maikaʻi a me ke kūpaʻa wela, a me ke kūpaʻa kemika a me ke olaola maikaʻi. No laila, he nui nā noi 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, ʻo ka pilikia nui me PEEK ua hōʻike ʻia ʻo ka osseointegration maikaʻi ʻole. ʻO ka holoʻokoʻa, akā naʻe, ʻo ka hoʻomohala ʻana o ka heleuma PEEK ua alakaʻi i ka lawe 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 e hoʻopiha i nā hemahema o ka iwi no ka mea (1) loaʻa iā ia kahi ʻano mineral e like me ko ka iwi kanaka, (2) kona macro-porosity a me micro-porosity he osteoconductive, a (3) maikaʻi loa kona biocompatibility a me ka mechanical resistance. ʻAʻole like me ka β-TCP, ʻo ka hydroxyapatite he mea mineral maoli me ka pili i nā iwi a he biocompatible loa ia no ka mea ua like ia me ka 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 maʻamau he lima a i ʻole ka 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), ma laila e mālama ai i ka iwi a me ka hypothetically e ʻae ai no 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 loaʻa kahi heleuma, hiki ke hōʻemi ʻia ka pōʻino hui ma muli o ke kino heleuma palupalu.)

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

Inā ʻoe e ʻimi nei i kahi mea hiki ke hāʻawi i ka ikaika kiʻekiʻe, ka paʻakikī, a me ke kūpaʻa kemika, ʻo PEEK (polyetheretherketone) ke koho kūpono loa. ʻO PEEK kahi polymer hana kiʻekiʻe i lilo i mea kaulana i nā ʻoihana he nui ma muli o kāna mau waiwai mechanical 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 ka PEEK Anchors?

ʻO nā heleuma PEEK nā mea hoʻopaʻa i hana ʻia me ka mea PEEK i hoʻolālā ʻia e hāʻawi i ka heleuma ikaika a hilinaʻi i nā noi 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 haʻahaʻa kiʻekiʻe, hoʻololi i ka mahana, a me nā wahi paʻakikī.

Na waiwai o na heleuma PEEK

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

Ka ikaika kiʻekiʻe a me ka paʻakikī

Loaʻa i nā heleuma PEEK ka ikaika tensile kiʻekiʻe a me ka paʻakikī, e hoʻolilo iā lākou i mea kūpono 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

Paʻa loa nā heleuma PEEK 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

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

Biocompatibility

ʻO nā heleuma PEEK he biocompatible, e mālama pono iā lākou no ka hoʻohana ʻana i nā noi olakino a me nā niho. He mea ʻawaʻawa ʻole lākou a ʻaʻohe carcinogenic, e hoʻolilo iā lākou i kahi koho pili kaiapuni.

Noi o PEEK heleuma

Loaʻa i nā heleuma PEEK ka nui o nā noi, me:

Lapaau Lapaau a me Niho

Hoʻohana maʻamau ʻia nā heleuma PEEK i nā noi lapaʻau a me nā niho, e like me nā implants orthopedic, implants dental, a me nā implants spinal. 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, avionics, a me nā ʻāpana 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 aila a me ke kinoea ma muli o ko lākou kūʻē ʻana i ke kaomi kiʻekiʻe, nā hoʻololi o ka mahana, a me nā kemika. Hoʻohana mau ʻia lākou i nā mea hana downhole, valves, a me nā pamu.

ʻO nā pono o nā heleuma PEEK

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

Māmā

He māmā nā heleuma PEEK i ka hoʻohālikelike ʻia me nā metala ʻē aʻe, e hoʻolilo iā lākou i mea kūpono no nā noi kahi e hopohopo ai ke kaumaha.

Lakiō kiʻekiʻe o ka ikaika a me ke kaumaha

Loaʻa i nā heleuma PEEK kahi lākiō kiʻekiʻe o ka ikaika-a-kaumaha, i mea kūpono no nā noi kahi e koi ʻia ai ka ikaika kiʻekiʻe akā pono e mālama ʻia ke kaumaha i ka liʻiliʻi.

Pale ʻino

Paʻa loa nā heleuma PEEK i ka corrosion, no laila kūpono lākou no ka hoʻohana ʻana i nā wahi ʻino.

ʻAʻahu Kūʻē

Kūleʻa loa nā heleuma PEEK i ka ʻaʻahu, no laila kūpono lākou no ka hoʻohana ʻana i nā noi kahi e hopohopo ai ka abrasion.

Māmā i ka Mīkini

He mea maʻalahi nā heleuma PEEK i ka mīkini, e hoʻolilo iā lākou i koho kūpono no nā noi he nui.

Ka hopena

ʻO nā heleuma PEEK kahi koho hoʻopaʻa paʻa kiʻekiʻe a 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 i ka aerospace a me nā ʻāpana automotive, hāʻawi nā heleuma PEEK i ka hilinaʻi a me ka ikaika o ka heleuma me nā waiwai maikaʻi e kū ai lākou mai nā mea ʻē aʻe.
