Shabakaddan waxa maamusha hal ama in ka badan oo ganacsi oo ay leedahay Informa PLC dhammaan xuquuqaha daabacaadana iyagaa iska leh.Xafiiska ka diwaan gashan ee Informa PLC waa 5 Howick Place, London SW1P 1WG. Ka diwaangashan England iyo Wales. Maya. 8860726.
Maanta, ku dhawaad ​​dhammaan goynta laser saxda ah ee biraha iyo kuwa aan biraha ahayn waxaa lagu sameeyaa iyadoo la adeegsanayo qalabka lagu qalabeeyay laser fiber ama ultrashort pulse (USP) lasers, ama mararka qaarkood labada. tubbada dabacsan, iyadoo la isticmaalayo mishiinada ku jira laser-fiber.
Sannado badan, inta badan micromachining laser ayaa la sameeyay iyadoo la isticmaalayo lasers nanosecond adag-state loo yaqaan lasers DPSS.Si kastaba ha ahaatee, tani hadda si buuxda u bedelay mahad horumarinta laba gebi ahaanba kala duwan, oo sidaas daraaddeed dhameystir, noocyada laser.Originally horumariyo isgaarsiinta, laser fiber ayaa qaan galay qalab workhorse processing lasers in warshado badan, inta badan at sababo u dhow-infrared ay ku guulaysto dhismaha. scalability awood toos ah.This natiijada in lasers in ay yihiin is haysta, aad loo isku halleyn karo, oo ay fududahay in la dhexgalo mashiinada gaarka ah, iyo guud ahaan bixiyaan qiimo hoose ee lahaanshaha ka badan noocyada laser ka weyn. Muhiimad u ah micromachining, laydhka wax soo saarka waxaa lagu diiradda saari karaa meel yar oo nadiif ah oo kaliya dhowr microns dhexroor, sidaas darteed waxay ku habboon yihiin goynta-xalinta sare, alxanka iyo wax soo saarka aad u dabacsan yihiin. Heerarka u dhexeeya hal tallaal ilaa 170 kHz. Iyada oo ay la socoto awoodda la cabbiri karo, tani waxay taageertaa goynta degdega ah iyo qodista.
Si kastaba ha noqotee, faa'iido darrooyinka suurtagalka ah ee laser-ka fiber-ka ee micromachining waa mashiinnada sifooyin yaryar iyo / ama qaybo khafiif ah, qaybo jilicsan garaaca garaaca femtosecond-ka tirtir dhibaatada HAZ.
Iyada oo leysarka USP, inta badan kulaylka dheeraadka ah ee la xidhiidha goynta ama geeddi-socodka qodista waxaa lagu qaadaa qashinka la saaray ka hor inta aan la helin wakhti lagu faafiyo walxaha ku hareeraysan. USP lasers oo leh wax soo saarka picosecond ayaa muddo dheer loo isticmaalay codsiyada micromachining ee ku lug leh balaastikada, semiconductors, ceramics, iyo biraha qaarkood (picoseconds = 10ts ee biraha birta ah ee birta ah ee birta ah ee birta ah ee birta ah). heerkulka sare ee kulaylka sare iyo cabbirka yar waxay ka dhigan tahay in lasers picosecond had iyo jeer ma bixiyaan natiijooyinka la hagaajiyay ee caddaynaya kharashka korodhka ah ee lasers USP hore. Tani hadda way isbedeshay iyadoo la raacayo imaanshaha heerka warshadaha femtosecond lasers (femtosecond = 10-15 seconds) tusaale ahaan Coherent Inc.'s Monaco ee taxanaha lasers, waxay ka dhigan tahay wax soo saarkoodu waa laydhka oo dhan. biraha loo isticmaalo qalabka caafimaadka, oo ay ku jiraan birta, platinum, dahab, magnesium, cobalt-chromium, titanium, iyo in ka badan, iyo sidoo kale non-metals. Halka isku dhafka muddada gaaban ee garaaca wadnaha iyo tamarta hoose ee garaaca wadnaha ay ka hortagto waxyeelada kulaylka (HAZ), heerka sare (MHz) celceliska heerka celceliska wuxuu hubinayaa xawaaraha wax-soo-saarka qiimaha-wax-ku-ool ah ee qalabyo badan oo qiimo sare leh.
Dabcan, ku dhawaad ​​ma jiro qof ka mid ah warshadeena u baahan hal laser. Halkii, waxay u baahan yihiin mishiin ku salaysan laysarka, waxaana hadda jira mashiinno badan oo khaas ah oo loogu talagalay goynta iyo qodista aaladaha caafimaadka.Tusaale ahaan waa Coherent's StarCut Tube series, kaas oo loo isticmaali karo lasers fiber, lasers femtosecond, ama sida nooc isku dhafan oo lagu daro labada nooc ee laser.
Maxaa loola jeedaa takhasuska qalabka caafimaadka Mashiinka isku midka ah waa inuu qabtaa labadaba si loo kordhiyo qiimaha. Baahiyahan waxaa badanaa la buuxiyaa iyadoo la siinayo dhidibo badan oo CNC ah oo la xakameeyey (xyz iyo rotary) dhaqdhaqaaqa iyo HMI-ga isticmaala-saaxiibtinimo ee barnaamijka fudud iyo kantaroolka.In the case of StarCut Tube, tube tube tube cusub doorasho yimaado la majaladda loading dhinaca (loo yaqaan StarFeed) ee tuubooyinka ilaa 3 m ee dhererka iyo wax soo saarka si buuxda u gooyay alaabta.
Debacsanaanta habka mishiinada kuwan waxaa sii wanaajiyey by taageerada goynta qoyan iyo qalalan iyo si fudud la hagaajin karo nozzles bixinta hababka u baahan gargaar gaas.Spatial xallinta ayaa sidoo kale si gaar ah muhiim u ah machining qaybo aad u yar, taas oo macnaheedu yahay in xasiloonida thermomechanical baabi'iyo saamaynta gariirka inta badan la kulmaan in dukaamada mishiinka.The StarCut Tube kala duwan buuxin baahida this by dhismaha oo dhan goynta sagxad ah granate.
NPX Medical waa soo saaraha qandaraas cusub oo cadaalad ah oo bixiya naqshadeynta, injineernimada iyo adeegyada goynta laser-ka saxda ah ee soosaarayaasha qalabka caafimaadka.Founded in 2019, shirkaddu waxay dhistay sumcad xagga warshadaha ee alaabada tayada leh iyo jawaab celinta, taageeridda aalado kala duwan oo ay ka mid yihiin stent, implants, stents valve iyo tuubooyinka gaarsiinta dabacsan ee qalliinnada isku midka ah ee kala duwan, hababka qalliinka laf-dhabarka, xididdada wadnaha Qalliinka lafaha, haweenka, iyo caloosha iyo mindhicirka. Its cutter laser ugu weyn waa StarCut Tube 2 + 2Â oo leh StarFiber 320FC oo leh celcelis ahaan awoodda 200 watts.Mike Brenzel, mid ka mid ah aasaasayaasha NPX, ayaa sharxay in "aasaasayaashu ay keenaan sanado hore oo qalab caafimaad iyo khibrad wax soo saar leh - in ka badan 90 sano oo khibrad leh oo laser ah" shaqadu waxay ku lug leedahay goynta Nitinol waxaanan horayba u ognahay in laser-ka fiber-ku uu bixin karo xawaaraha iyo tayada aan u baahanahay. Qalabka sida tuubooyinka dhumucdiisuna waxay u baahan yihiin xawaalad, iyo laser USP wuxuu noqon karaa mid aad u gaabis ah baahidayada marka lagu daro amarrada wax-soo-saarka mugga sare - waxaan ku takhasusay qaybo yaryar oo qaybo ah - kaliya inta u dhaxaysa 5 iyo 150 - hadafkeenu waa in la dhamaystiro kuwan yar yar, samaynta qaabaynta qaabaynta maalmo yar, oo ay ku jiraan qaybo yar oo naqshadeyn ah, oo ay ku jiraan dhawr maalmood oo barnaamijka naqshadeynta ah, oo ay ku jiraan dhowr maalmood oo barnaamijka naqshadeynta ah, oo ay ku jiraan qaybo yaryar dib-u-habaynta iyo kormeerka, marka la barbardhigo toddobaadyada ka dib markii la dalbado shirkadaha waaweyn. "Marka laga soo tago xawaaraha, Brenzel wuxuu xusay kalsoonida mashiinka faa'iido weyn, oo aan u baahnayn hal adeeg oo wac ah bilihii 18 ee la soo dhaafay ee hawlgalka joogtada ah.
Jaantus 2. NPX waxay bixisaa noocyo kala duwan oo kala duwan oo ka-hortagga wax-soo-saarka. Maaddada halkan lagu muujiyey waa T316 bir aan lahayn oo leh 5mm OD iyo dhumucdiisuna tahay 0.254mm. Qaybta bidixda waa la gooyay / microblasted iyo qaybta saxda ah waa koronto.
Marka laga soo tago qaybaha nitinol, shirkadu waxay sidoo kale ka dhigtaa isticmaalka ballaaran ee cobalt-chromium alloys, tantalum alloys, titanium alloys iyo noocyo badan oo birta ah ee caafimaadka ah.Jeff Hansen, Maareeyaha farsamaynta Laser, wuxuu sharxayaa: "Dabacsanaanta mishiinka waa hanti kale oo muhiim ah, taas oo noo ogolaanaysa inaan taageerno jarista qalab aad u kala duwan, oo ay ku jiraan tuubo iyo flatm0. Qaar ka mid ah tuubooyinkan ayaa ah 0.012 ″ oo keliya, iyo saamiga sare ee awoodda ugu sarreysa ee leysarka fiber-ka ee ugu dambeeyay waxay kordhisaa xawaarahayaga goynta iyadoo aan weli bixinno tayada cirifka ee la doonayo.
Marka lagu daro goynta saxda ah iyo jawaab celinta degdega ah, NPX waxay sidoo kale bixisaa tiro balaadhan oo ah tignoolajiyada post-processing, iyo sidoo kale adeegyada design dhamaystiran in ay ka faa'iidaystaan ​​ay waayo-aragnimo ballaaran in industry.These farsamooyinka ka mid ah electropolishing, sandblasting, pickling, alxanka laser, goobta kulaylka, samaynta, passivation, Af heerkulka imtixaanka, iyo daal tijaabin, kuwaas oo dhan kuwaas oo fure u ah si ay u dhamaystiraan qalabaynta Nitinzel ku sheegay in ay dhamaystiraan qalab-Breinzel. "sida caadiga ah waxay kuxirantahay haddii aan ka hadleyno codsi daal sare leh ama daal hooseeya. Tusaale ahaan, qayb ka mid ah daalka sare sida waalka wadnaha ayaa laga yaabaa inuu foorarsado bilyan jeer in ka badan inta uu nool yahay sida ka-shaqeynta ka dib Talaabada, waxaa muhiim ah in la isticmaalo sandblasting si loo kordhiyo radius ee geesaha oo dhan. Laakiin qaybaha hoose ee daalka sida nidaamyada bixinta ama hagaha - inta badan uma baahna boostada ballaaran. " Marka la eego khibradda naqshadeynta, Brenzel wuxuu sharxayaa, hadda waxaa jira ilaa seddex meelood oo macaamiisha ah sidoo kale waxay isticmaalaan adeegyadooda naqshadeynta si ay uga faa'iideystaan ​​​​caawinta iyo xirfadaha NPX si ay u helaan oggolaanshaha FDA. Shirkadu waxay aad ugu fiican tahay inay u rogaan fikradda "sketch napkin" ee badeecada qaabkeeda ugu dambeeya muddo gaaban gudaheed.
Motion Dynamics (Fruitport, MI) waa soo saaraha ilo yar yar oo caado ah, gariiradaha caafimaadka iyo shirarka silig kuwaaso hadafkoodu yahay in la xaliyo mashaakilaadka macaamiisha, iyadoon loo eegin sida adag ama u muuqata mid aan macquul ahayn, wakhtiga ugu gaaban ee suurtogalka ah. golayaasha
Sida hore loo soo sheegay, doorashada fiber ama laser USP waa arrin ka mid ah doorbidida injineernimada iyo sidoo kale nooca qalabka iyo hababka la taageeray. Chris Witham, Madaxweynaha Motion Dynamics, sharaxay: "Iyadoo ku saleysan model ganacsi in uu yahay mid aad diirada u saaran alaabta neurovascular, waxaan bixin karaa natiijooyin kala duwan in design, fulinta iyo adeegga. Waxaan kaliya isticmaali goynta laser si ay u soo saaraan qaybaha aan u isticmaalno gudaha-guriga, noqdaan kuwo gaar ah, si ay u soo saaraan qaybaha sare ee guriga. iyo sumcadda, ma bixinno goynta laser sida adeeg qandaraas ah Waxaan ogaanay in jarista laser-ka ee aan sameyno si fiican loo sameeyo lasers USP, iyo sanado badan waxaan isticmaalayay Tube StarCut oo leh mid ka mid ah laser-yadan, sababtoo ah baahida xooggan ee alaabtayada, waxaan haysanaa laba saacadood oo 8 ah maalintii, mararka qaarkood xitaa saddex isbeddel, iyo 2019 si aan u helno taageerada Tube Mid ka mid ah moodooyinka cusub ee isku-dhafka ah ee femtosecond USP lasers iyo fiber lasers waxaan sidoo kale ku dhejinnay StarFeed loader / loader si aan si buuxda u habeyno goynta - hawlwadeenku si fudud ayuu u dhigayaa meel bannaan Tubada waxaa lagu shubay feederiyaha iyo barnaamijka hawlgalka software ee alaabta ayaa la bilaabay.
Jaantuska 3. Tuubada gudbinta birta ah ee dabacsan (oo lagu ag tusay qalin masar) ayaa lagu gooyay leysarka femtosecond ee Monaco.
Witham waxay ku dartay in halka ay marmar u isticmaalaan mishiinka goynta guri, in ka badan boqolkiiba 95 wakhtigoodu waxay ku kharash gareeyaan abuurista ama wax ka beddelka alaabooyinka cylindrical ee isku xidhka tuubada steerable, kuwaas oo ah hypotubes, gariiradda iyo spirals, oo ay ku jiraan jarida talooyinka profiled iyo Godadka gooyay. Qaybahaas ayaa ugu dambeyntii loo isticmaalaa hababka sida aneurysm-ka ee ka saarista biraha kala duwan oo ay ku jiraan isticmaalka xinjirowga dhiigga. bir, dahab saafi ah, platinum iyo nitinol.
Jaantus 4. Dhaqdhaqaaqa Dhaqdhaqaaqa wuxuu kaloo si aad ah u isticmaalaa alxanka laysarka
Waa maxay fursadaha laysarka?Witham wuxuu sharraxay in tayada cirifka wanaagsan iyo kerfs-yada ugu yar ay muhiim u yihiin inta badan qaybahooda, sidaas darteed waxay markii hore doorbideen lasers USP. Intaa waxaa dheer, mid ka mid ah qalabka shirkadu isticmaasho mid ka mid ah lasers-kaas ma gooyn karo, oo ay ku jiraan qaybaha dahabiga ah ee yar yar ee loo isticmaalo calaamadaha shucaaca ee qaar ka mid ah alaabteeda. Laakiin wuxuu ku daray in fursadaha cusub ee isku-dhafka ah, oo ay ku jiraan xawaaraha laser-ka iyo USPimizing fursadaha. "Shaki kuma jiro in fiber optics ay ku siin karaan xawaare sare," ayuu yiri. "Laakiin sababtoo ah our codsiga gaarka ah diiradda, tani sida caadiga ah ka dhigan tahay nooc ka mid ah post-processing, sida kiimikada iyo ultrasonic nadiifinta ama electropolishing. Sidaa darteed haysashada mishiinka hybrid waxay noo ogolaanaysaa in aan dooran taas guud ahaan habka - USP keligiis ama fiber iyo post-processing maaraynta - ugu fiican ee qayb kasta oo ka mid ah. Waxay noo ogolaanaysaa in ay sahamiyaan dhexroorka machi qayb ka mid ah, gaar ahaan qayb ka mid ah dhumucdiisuna waa weyn ee derbiga. ayaa ku lug leh: xitaa goynta degdega ah ee leysarka fiber-ka, Kadibna u isticmaal laser femtosecond si aad u goyso ganaax. Waxa uu rajaynaya in leysarka USP uu ahaan doono doorkooda kowaad sababtoo ah inta badan goyntooda laysarka waxa ku lug leh dhumucyada gidaarka inta u dhaxaysa 4 iyo 6, in kasta oo ay la kulmaan dhumucyada derbiyada u dhexeeya 1-20 adiga. Dhuumaha birta ah ee dhexdiina
Gabagabadii, goynta laser-ka iyo qodista waa geeddi-socod muhiim ah oo ku saabsan soo-saarka aaladaha caafimaadka ee kala duwan. Maanta, Thanks to horumarka tignoolajiyada laser-ka aasaasiga ah iyo mashiinnada aadka loo hagaajiyay ee loo habeeyey baahiyaha gaarka ah ee warshadaha, geeddi-socodkani way fududahay in la isticmaalo oo keeno natiijooyin ka wanaagsan sidii hore.
