Kune vatengi vanotsvaga yakaderera maMOQ uye yakakwira zvigadzirwa zvakasiyana, Multispecialty Suppliers inopa yakaderera MOQ kugadzirisa, kupera-kusvika-kumagumo zvigadziriso zvekugadzirisa, uye akawanda-mapoka ekutenga, achitsigirwa neindasitiri yavo yakapfuma uye ruzivo rwesevhisi uye kunzwisisa kwakasimba kwemafambiro echigadzirwa chiri kubuda.
Ⅰ.Chii chinonzi PEEK screws?
PEEK (polyetheretherketone) screws inogadzirwa kubva kuhunyanzvi hweinjiniya epurasitiki ine yakanakisa insulation, corrosion resistance, high-temperature resistance, uye flame retadancy. Iwo anoshandiswa zvakanyanya mumidziyo yekurapa, midziyo yemagetsi, aerospace, uye mamwe minda.
Material Properties
PEEK ndeye semi-crystalline specialty engineering plastic ine yakanakisa makemikari kuramba pakati peinjiniya mapurasitiki, ichinyungudika chete muyakaomeswa sulfuric acid. Zvimiro zvaro zvemagetsi zvinosanganisira kupisa kupisa (kuenderera kwekushanda tembiricha kusvika ku260 ° C), kupfeka kusagadzikana, kupisa kwemoto (UL94 V-0 flame retardancy), uye hydrolysis kuramba.
Applications
Zvishandiso zvekurapa: Nekuda kweiyo isiri-magnetic, insulating, uye corrosion-resistant zvivakwa, zvakakodzerwa nemidziyo yekuvhiya.
Electronic Devices: Inoshandiswa mune chaiyo zvikamu seIC wafer vatakuri uye LCD kugadzira jigs.
Aerospace: Inowanzo shandiswa mukuda maapplication akadai semidziyo yemagetsi emhepo uye zvisimbiso zvemusuwo wendege.
Marudzi ekuvaka
Mamwe mamodheru anosimbiswa negirazi faibha (semuenzaniso, 30% yegirazi faibha) kuwedzera ma mechanic properties. Iwo anowanzo shandiswa mune akasarudzika-akaumbwa zvimiro senge hermaphroditic screws uye knurled thumb screws.
Ⅱ.Vanoisa screws mumabvi ako kuitira ACL operation?
Zvikumbiro zvinowanzoshandiswa kuchengetedza magraft panguva yekuvhiyiwa kweanterior cruciate ligament (ACL). Panguva yekuvakazve ACL, chiremba anovhiya anoshandisa arthroscopy kuita zviduku zvishoma zvakapoteredza mabvi akabatanidzwa. Mushure mokubvisa ACL yakakuvadzwa, autologous kana allogeneic graft inoiswa mujoini. Screws, anchors, uye mamwe maturusi anoshandiswa kuchengetedza girafu kumubhedha wepfupa kuti ugadzikane.
Chinangwa cheScrews
Screws inonyanya kushandiswa kuchengetedza anchor grafts (senge patellar tendon uye hamstring tendon) kune femur uye tibia, ichidzivirira kuti irege kutsvedza kana kudonha. Rudzi urwu rwekugadzirisa inzira yakajairika panguva yekuvhiyiwa arthroscopic uye inovimbisa kugadzikana kwemabvi mushure mekushanda.
Postoperative Precautions
Mushure mekuvhiyiwa, brace kana madondoro anodiwa kuchengetedza mabvi akabatanidzwa, uye kurapa kwemuviri uye kurovedza muviri kunoitwa. Zvikururu kazhinji hazvidi kubviswa; zvishoma nezvishoma vanova chikamu chebhonzo sezvo mapfupa anobatana.
Ⅲ.Is PEEK sikuruu inogona kudhindwa here?
Polyetheretherketone (PEEK) screws haisi-biodegradable. Nekuda kwezvimiro zvavo zvenyama, havagone kuparara mumuviri wemunhu uye zvinoda kuvhiyiwa kubviswa.
Zvikonzero zveNon-Biodegradability
PEEK (polyetheretherketone) ndeyepamusoro-molecular-huremu hwepolymer inoratidzwa nekusimba kwepamusoro uye kugadzikana. Haikwanise kuderedzwa mumuviri wemunhu kuburikidza nekuora enzymatic kana kuora. Mumashandisirwo emazuva ano ekurapa, PEEK screws inonyanya kushandiswa mu anterior cruciate ligament reconstruction uye majoint fusion surgeries, izvo zvinoda kugadziriswa kwenguva refu kwepfupa kana nyoro. Nokudaro, zvinyorwa zvinofanira kuratidza kugadzikana kwenguva refu.
