yakakwirira kuchena tungsten waya tungsten guidewire scalpel yekurapa
A guidewire mumidziyo yekurapa iwaya yakatetepa, inochinjika inoshandiswa kutungamira uye kuisa midziyo yekurapa, senge catheter, mukati memuviri panguva dzakasiyana dzekurapa. Guidewires anowanzo shandiswa mune zvishoma invasive uye kupindira maitiro ekupfuura nemutsinga dzeropa, arteries, uye zvimwe anatomical zvimiro. Izvo zvakagadzirirwa kuti zvikwanise kuchinjika uye zvinopa tsigiro yekuiswa kwemidziyo yekurapa, kuve nechokwadi chekufamba uye kwakadzora kufamba mukati memuviri. Guidewires inoita basa rakakosha mune rakasiyana siyana rekushandisa kwekurapa, kusanganisira yemoyo, radiology, uye endovascular kuvhiyiwa.
Tungsten inoshandiswa mumashandisirwo akasiyana siyana nekuda kwehunhu hwayo hwakanaka. Inoshandiswa zvakanyanya nekuda kwekunyungudika kwayo kwakakwira, yakanaka thermal conductivity, corrosion resistance uye oxidation kuramba. Izvi zvivakwa zvinoita kuti tungsten inyanyokosha munzvimbo dzekupisa kwepamusoro senge zvinhu zvekudziya, magetsi anobatika uye mavira emaindasitiri. Pamusoro pezvo, simba rayo, density uye biocompatibility inoita kuti ive yakakodzera kushandiswa mumidziyo yekurapa senge waya dzekutungamira uye zviridzwa zvekuvhiya. Iko kusanganiswa kwezvivakwa izvi kunoita kuti tungsten ive inochinja-chinja uye yakakosha zvinhu zvinogona kushandiswa mune dzakasiyana siyana maindasitiri, ekutengesa uye ekurapa zvikumbiro.
Ehe, tungsten haina kunyungudika mumvura, zvinoreva kuti haiite kana kunyungudika mumvura. Ichi chivakwa chinoita kuti tungsten ikwane kushandiswa mumashandisirwo uko kuratidzwa kwemvura kana zvimwe zvinwiwa kuri kutariswa, senge mune mamwe maindasitiri nekugadzira maitiro.
