Hoʻohana ʻia kēia pūnaewele e hoʻokahi a ʻoi aku paha nā ʻoihana a Informa PLC a na lākou nā kuleana kope a pau. ʻO ke keʻena i hoʻopaʻa inoa ʻia ʻo Informa PLC ʻo 5 Howick Place, London SW1P 1WG.Registered in England and Wales.No. 8860726.
I kēia lā, kokoke i ka ʻoki ʻoki ʻana i nā metala a me nā mea ʻole i hana ʻia me ka hoʻohana ʻana i nā mea hana i lako me nā laser fiber a i ʻole nā ​​lasers ultrashort pulse (USP), a i kekahi manawa ʻelua. ka paipu, me ka hoʻohana 'ana i nā mīkini e hoʻokomo i ka fiber lasers. Motion Dynamics manufactures subassemblies, e like me "huki uwea" hui mua i hoʻohana 'ia i loko o neurology, utilizing i ka mīkini e komo ana i ka USP femtosecond laser a me kekahi o ka hou hybrid nenoai me ka femtosecond a me ka fiber lasers no ka maʻalahi a me ka Versatility.
No nā makahiki he nui, ua hana ʻia ka hapa nui o ka laser micromachining me ka hoʻohana ʻana i nā lasers nanosecond solid-state i kapa ʻia he lasers DPSS. Akā naʻe, ua hoʻololi loa kēia i kēia manawa i ka hoʻomohala ʻana o ʻelua ʻokoʻa like ʻole, a no laila hoʻohui ʻia, nā ʻano laser. ʻO kēia ka hopena i nā lasers i paʻa, hilinaʻi nui, a maʻalahi hoʻi e hoʻohui i nā mīkini kūikawā, a hāʻawi maʻamau i ke kumukūʻai haʻahaʻa o ka ʻona ma mua o nā ʻano laser kahiko. ʻO ka mea nui no ka micromachining, hiki ke hoʻopili ʻia ka beam puka i kahi wahi liʻiliʻi, maʻemaʻe o nā microns wale nō ke anawaena, no laila ua kūpono lākou no ka ʻoki kiʻekiʻe, wili a me ka drilling. 170 kHz. Me ka mana scalable, kākoʻo kēia i ka ʻoki wikiwiki a me ka wili.
Eia naʻe, ʻo kahi pōʻino o nā laser fiber i ka micromachining ʻo ia ka mīkini ʻana i nā hiʻohiʻona liʻiliʻi a / a i ʻole nā ​​ʻāpana palupalu. nā pulupulu—hoʻopau i ka pilikia HAZ.
Me nā lasers USP, lawe ʻia ka hapa nui o ka wela hou e pili ana i ka ʻoki ʻana a i ʻole ke kaʻina hana ʻana i ka ʻōpala i hoʻokuʻu ʻia ma mua o ka manawa e hoʻopuehu ai i loko o nā mea a puni. ʻO ka conductivity a me ka liʻiliʻi liʻiliʻi ʻo ia ka picosecond lasers ʻaʻole i hāʻawi mau i nā hopena i hoʻomaikaʻi ʻia e hōʻoia i ka hoʻonui ʻia o ke kumukūʻai o nā lasers USP mua. nā mea hana, me ke kila kila, platinum, gula, magnesium, cobalt-chromium, titanium, a me nā mea ʻē aʻe, a me nā metala ʻole. ʻOiai ka hui pū ʻana o ka manawa pulse pōkole a me ka ikehu pulse haʻahaʻa e pale ai i ka pōʻino wela (HAZ), ʻo ke kiʻekiʻe (MHz) repetition rate e hōʻoia i ka wikiwiki throughput kumu kūʻai no nā mea lapaʻau kiʻekiʻe.
ʻOiaʻiʻo, ʻaneʻane ʻaʻohe mea o kā mākou ʻoihana e pono ai i hoʻokahi laser. Akā, pono lākou i ka mīkini laser-based, a i kēia manawa he nui nā mīkini kūikawā i hoʻopaʻa ʻia no ka ʻoki ʻana a me ka ʻeli ʻana i nā mea lapaʻau.
He aha ka manaʻo o ka hoʻonaʻauao kūikawā? ʻO ka hapa nui o kēia mau mea hana i hana ʻia i nā ʻāpana liʻiliʻi e pili ana i nā hoʻolālā maʻamau. Pono ka mīkini hoʻokahi e lawelawe i nā mea ʻelua e hoʻonui i kona waiwai. Hoʻokō pinepine ʻia kēia mau pono ma ka hāʻawi ʻana i ka neʻe multi-axis CNC mana (xyz a rotary) a me ka HMI hoʻohana-aloha no ka hoʻonohonoho maʻalahi a me ka control.
Hoʻonui hou ʻia ke kaʻina hana o kēia mau mīkini e ke kākoʻo no ka ʻoki ʻana a me ka maloʻo a me ka maʻalahi o ka hoʻouna ʻana i nā nozzles no nā kaʻina e pono ai ke kōkua gas.
ʻO ka NPX Medical kahi mea hana aelike hou e hāʻawi ana i ka hoʻolālā, ʻenekinia a me nā lawelawe ʻoki laser precision i nā mea hana lāʻau lapaʻau. gynecological, and gastrointestinal surgery.Its major laser cutter is the StarCut Tube 2+2Â with a StarFiber 320FC with a average power of 200 watts. Mike Brenzel, one of NPX's founders, explained that "ka mea hookumu e lawe mai i na makahiki o ka hoʻolālā lāʻau lapaʻau a me ka 'ike hana - 'oi aku ma mua o 90 mau makahiki i ka huina", me ka 'ike mua me ka mīkini Nitino. ʻoki a ua ʻike mākou ua hiki i nā laser fiber ke hāʻawi i ka wikiwiki a me ka maikaʻi a mākou e pono ai. No nā mea like me nā paipu paʻa paʻa a me nā puʻuwai puʻuwai, pono mākou i ka wikiwiki, a lohi paha ka USP laser no kā mākou mau pono. ka nānā ʻana, hoʻohālikelike ʻia me nā pule ma hope o ke kau ʻana i kahi kauoha no nā ʻoihana nui.
Hōʻike 2. Hāʻawi ʻo NPX i nā ʻano koho post-processing. ʻO ka mea i hōʻike ʻia ma ʻaneʻi ʻo T316 stainless steel me ka mānoanoa pā 5mm OD a me 0.254mm. Ua ʻoki ʻia ka ʻaoʻao hema / microblasted a ua electropolished ka ʻaoʻao ʻākau.
Ma waho aʻe o nā ʻāpana nitinol, hoʻohana nui ka hui i nā ʻāpana cobalt-chromium, nā ʻāpana tantalum, nā ʻāpana titanium a me nā ʻano ʻano he nui o nā mea kila stainless. ʻO kekahi o kēia mau paipu he 0.012 ″ ID wale nō, a ʻo ka ratio kiʻekiʻe o ka mana kiʻekiʻe i ka mana awelika o nā laser fiber hou e hoʻonui i kā mākou wikiwiki ʻoki ʻoiai e hāʻawi ana i ka maikaʻi o ka ʻaoʻao i makemake ʻia.
Ma waho aʻe o ka ʻoki pololei a me ka pane wikiwiki, hāʻawi pū ʻo NPX i kahi ʻenehana holoʻokoʻa holoʻokoʻa, a me nā lawelawe hoʻolālā holoʻokoʻa e hoʻohana ai i kāna ʻike nui i ka ʻoihana. i ʻōlelo ʻia, "e hilinaʻi maʻamau inā mākou e kamaʻilio e pili ana i kahi noi haʻahaʻa haʻahaʻa a i ʻole ka luhi. Ma ke ʻano o ka ʻike hoʻolālā, wehewehe ʻo Brenzel, aia i kēia manawa e like me ʻEkolu hapahā o nā mea kūʻai aku e hoʻohana i kā lākou lawelawe hoʻolālā e hoʻohana i ke kōkua a me nā mākau o NPX i ka loaʻa ʻana o ka ʻae FDA.
ʻO ka Motion Dynamics (Fruitport, MI) he mea hana i nā puna wai liʻiliʻi, nā coils olakino a me nā hui uea nona ka misionari e hoʻoponopono i nā pilikia o ka mea kūʻai aku, ʻaʻohe mea paʻakikī a ʻike ʻole ʻia paha, i ka manawa pōkole loa. na anaina.
E like me ka mea i ʻōlelo mua ʻia, ʻo ke koho ʻana i ka fiber a i ʻole USP laser he mea ia o ka makemake ʻenekinia a me ke ʻano o nā mea hana a me nā kaʻina i kākoʻo ʻia. Ua wehewehe ʻo Chris Witham, Pelekikena o Motion Dynamics: "Ma muli o kahi ʻoihana ʻoihana e nānā nui ʻia i nā huahana neurovascular, hiki iā mākou ke hāʻawi i nā hopena like ʻole i ka hoʻolālā, hoʻokō a me ka lawelawe. ʻAʻole mākou e hāʻawi i ka ʻokiʻoki ʻana i ka laser ma ke ʻano he lawelawe ʻaelike, ʻoi aku ka maikaʻi o ka hana ʻana me nā lasers USP, a no nā makahiki he nui wau i hoʻohana ai i kahi StarCut Tube me kekahi o kēia mau lasers e hele pū me kekahi o nā hiʻohiʻona hou o ka femtosecond USP lasers a me ka fiber lasers Ua hoʻopili pū mākou me kahi StarFeed loader / unloader i hiki iā mākou ke hoʻomaʻamaʻa piha i ka ʻoki ʻana - waiho wale ka mea hoʻohana i ka blank Ua hoʻokomo ʻia ka pahu i loko o ka mea hānai a hoʻomaka ka polokalamu hana polokalamu no ka huahana.
Kiʻi 3. Ua ʻoki ʻia kēia paipu hāʻawi kila kuhili ʻole (e hōʻike ʻia ma ka ʻaoʻao o kahi holoi penikala) me ka laser Monaco femtosecond.
Hoʻohui ʻo Witham ʻoiai lākou e hoʻohana i ka mīkini no ka ʻoki palahalaha, ʻoi aku ma mua o 95 ka nui o ko lākou manawa i hoʻohana ʻia i ka hana ʻana a i ʻole ka hoʻololi ʻana i nā huahana cylindrical no kā lākou mau hui catheter steerable, ʻo ia hoʻi nā hypotubes, coils a me nā spirals, me ka ʻoki ʻana i nā ʻōlelo aʻoaʻo a me nā ʻoki ʻoki. platinum a me ka nitinol.
Kiʻi 4. Hoʻohana nui ka Motion Dynamics i ka welding laser. Ma luna aʻe, ua wili ʻia ka coil i ka ʻoki ʻoki laser.
He aha nā koho laser? Ua wehewehe ʻo Witham he mea koʻikoʻi ka maikaʻi o ka lihi maikaʻi a me nā kerf liʻiliʻi no ka hapa nui o kā lākou mau mea, no laila ua makemake mua lākou i nā lasers USP. Eia kekahi, ʻaʻohe o nā mea a ka hui e hoʻohana ai e hiki ke ʻoki ʻia e kekahi o kēia mau lasers, me nā mea gula liʻiliʻi i hoʻohana ʻia e like me nā hōʻailona radiopaque i kekahi o kāna mau huahana. ʻAʻole kānalua ka hiki i ka fiber optics ke hāʻawi i nā wikiwiki kiʻekiʻe, "i ʻōlelo ai ʻo ia. "Akā, ma muli o kā mākou noi kikoʻī, ʻo ia ka mea maʻamau i kekahi ʻano o ka hoʻomaʻemaʻe ʻana, e like me ka hoʻomaʻemaʻe kemika a me ka hoʻomaʻemaʻe ultrasonic a i ʻole electropolishing. ʻoki wikiwiki me nā laser fiber, a laila e hoʻohana i ka laser femtosecond no ka ʻoki maikaʻi. Manaʻo ʻo ia e hoʻomau ka laser USP i kā lākou koho mua no ka mea ʻo ka hapa nui o kā lākou ʻoki laser e pili ana i ka mānoanoa o ka pā ma waena o 4 a me 6 ʻoe, ʻoiai ke hālāwai nei lākou i nā mānoanoa pā mai ka 1-20 ʻoe. ʻO nā paipu kila ma waena o ʻoe.
I ka hopena, ʻo ka ʻoki ʻana a me ka hoʻoheheʻe ʻana i nā kaʻina hana koʻikoʻi i ka hana ʻana i nā mea lapaʻau like ʻole.
