Lub Pinnacle Ntawm Precision Manufacturing: Yug Ntawm Ib Tug Kho Mob Puncture Needle

Ib rab koob zoo li yooj yim kho mob yog tsim los ntawm cov txheej txheem engineering ua tiav ntawm qhov ntsuas micrometer. Cov kev xav tau rau qhov raug, huv thiab sib xws yog piv rau cov kev lag luam aerospace thiab semiconductor. Nrog rau kev siv rau siab - cov txheej txheem tsim khoom tau hais hauv cov ntaub ntawv siv (xws li 5- axis CNC machining, electropolishing thiab nruj zoo soj ntsuam), daim ntawv no tau txheeb xyuas qhov ua tiav thiab nruj tsim kev taug kev ntawm kev ua haujlwm siab kho mob rab koob los ntawm cov ntaub ntawv raw mus rau cov khoom tiav.

Theem I: Kev nruj nruj hauv kev tsim thiab cov khoom siv raw

1. Tsim thiab Simulation

Ua ntej lub cev tsim khoom pib, lub koob lub geometry (lub kaum sab xis, tus naj npawb ntawm bevels, puab kab noj hniav) thiab cov khoom siv kho tshuab (raug quab yuam, rigidity, toughness) yog simulated thiab optimized countless sij hawm ntawm lub computer - pab tsim (CAD) thiab finite element tsom xam (FEA) software. Qhov no ua kom pom cov ntaub so ntswg nkag nrog tsawg kawg nkaus raug mob.

2. Raw Material Control

Kev tsim khoom pib nrog kev soj ntsuam nruj ntawm kev kho mob - qib hlau raj lossis cov xov hlau. Txawm hais tias nws yog 316L stainless hlau tubing lossis nitinol hlau, tag nrho cov khoom siv raw yuav tsum tau nrog cov ntaub ntawv pov thawj ua raws li ASTM lossis ISO cov qauv, thiab rov qab- tshuaj xyuas thaum nkag mus rau hauv lub Hoobkas. Kev tshuaj xyuas suav nrog spectral tsom xam ntawm cov tshuaj muaj pes tsawg leeg, tshuaj ntsuam xyuas cov qauv metallographic thiab cov cuab yeej siv tshuab, kom lav qhov sib xws ntawm purity, grain loj thiab kev ua haujlwm.

Theem II: Ultra-Precision Machining thiab Forming

Qhov no yog theem tseem ceeb uas muab cov koob nrog nws cov duab thiab kev ua haujlwm tseem ceeb, muaj cov kev xav tau siab heev rau cov cuab yeej siv tshuab raug thiab tswj cov txheej txheem.

3. Koob raj tsim thiab txiav

High-precision, nyias-cov phab ntsa stainless hlau raj yog pub rau hauv Swiss- hom tshuab dhos tsis siv neeg lossis ntau-axis CNC tshuab cuab yeej. Cov tshuab no ua tiav ntau yam txheej txheem hauv ib lub clamping, nrog rau sab nraud cylindrical tig, tsau -ntev txiav thiab chaw nres nkoj chamfering, kom ntseeg tau qhov ncaj, roundness thiab qhov ntev ntev ntawm rab koob raj yog tswj ntawm qib micrometer.

4. Needle Tip Geometry forming – Lub hauv paus ntawm Technology

Lub taub hau yog tus ntsuj plig ntawm rab koob, thiab nws txoj kev tsim feem ntau yog ua tiav ntawm ultra- precision CNC sib tsoo tshuab nruab nrog super- pob zeb diamond nyuaj lossis CBN (cubic boron nitride) sib tsoo lub log. Los ntawm complex multi-axis linkage, lub raj kawg yog hauv av rau hauv cov duab geometric uas tau teev tseg los ntawm tus tsim:

- Ntau-bevel Cov Lus Qhia: Cov hom muaj xws li tri- cov lus qhia bevel (nrog peb txoj kev txiav kom raug) thiab penta- cov lus qhia bevel (ntse nrog qhov mob tsawg). Lub kaum sab xis ntawm txhua qhov bevel thiab kev hloov pauv arc yuav tsum tau tswj kom meej.

​

- Cwj mem lus qhia/pob zeb diamond tswv yim: Tsis muaj kev txiav ntug, cov lus qhia no thawb ib sab cov ntaub so ntswg los ntawm blunt expansion. Lawv tau siv rau cov koob tshuaj loog txha caj qaum thiab cov koob epidural kom txo tau txoj kev pheej hmoo ntawm kev txiav cov hlab ntsha thiab cov hlab ntsha.

​

- Cov Lus Qhia Rov Qab Bevel: Ib qho kev pabcuam me me ntxiv rau sab nraub qaum ntawm lub ntsiab txiav bevel kom sib npaug ntawm lub zog sab nraud thaum sib tsoo thiab tiv thaiv lub ntsej muag deflection.

5. Sab Qhov Ncauj thiab Kev Ua Haujlwm Tshwj Xeeb

Rau cov koob txhaj tshuaj biopsy thiab cov koob hauv tsev, cov grooves lossis sab qhov yuav tsum tau ua tiav ntawm phab ntsa ntawm lub koob raj. Precision laser txiav los yog micro- hluav taws xob tawm machining (micro-EDM) feem ntau yog siv los ua kom du, burr- qhib qhib dawb tsis muaj cua sov- thaj chaw cuam tshuam, zam kev cuam tshuam rau cov qauv zoo lossis cov ntaub so ntswg ntxiv.

Theem III: Kev kho cua sov thiab kev ua haujlwm tau txais txiaj ntsig

6. Kev kho cua sov (Rau Stainless Hlau)

Rau cov koob cores uas yuav tsum tau muaj siab hardness (xws li cov pob txha pob txha puncture koob cores), cov ntaub ntawv xws li 440C los yog 17-4PH hais nyob rau hauv cov ntaub ntawv siv yog siv, thiab undergo meej quenching thiab kub-kub tempering kom ua tau siab hardness thiab txaus toughness. Rau austenitic stainless hlau koob raj, kev kho tshuaj yog nqa tawm kom tshem tawm cov kev ntxhov siab thiab ua kom zoo dua corrosion.

7. Kev Kho Mob Zoo (Rau Nitinol)

Cov koob tsim nitinol yog raug rau cov kev cob qhia thermomechanical hauv ib qho kev sib tw tshwj xeeb, programming preset "memorized" zoo (ncaj los yog cov duab nkhaus) thiab superelasticity rau hauv cov khoom siv microstructure.

Theem IV: Nto Finishing thiab Tu - Qhov Kawg Barrier rau Biocompatibility

8. Electropolishing

Qhov no yog ib kauj ruam tseem ceeb los txhim kho rab koob. Cov koob yog immersed nyob rau hauv ib tug tshwj xeeb electrolyte, thiab microscopic protrusions nyob rau saum npoo yog xaiv yaj los ntawm ib tug electrochemical txheej txheem, uas ua rau ib daim iav - du thiab uniform nto. Cov txheej txheem no tsis tsuas yog tshem tawm tag nrho cov txheej txheem burrs thiab microcracks, txhim kho corrosion kuj zoo heev, tab sis kuj tseem txo qis kev tiv thaiv, nrog rau cov teebmeem zoo dua rau cov tshuab polishing.

9. Coating Deposition (yog tias tsim nyog)

Nyob rau hauv lub tshuab nqus tsev huv heev, lub cev vapor deposition (PVD) tshuab yog siv los tso ultra- tawv thiab lubricated coatings xws li pob zeb diamond-xws li carbon (DLC) los yog titanium nitride (TiN) nrog ib tug tuab ntawm ob peb micrometers ntawm rab koob los yog ncej, ntxiv zog sharpness, hnav tsis kam thiab lubricity.

10. Multi-theem Ultrasonic Ntxuav

Hauv chav tsev 10,000 lossis siab dua, cov koob tau dhau los ntawm ntau lub tshuab ntxhua khaub ncaws ultrasonic nrog cov qauv sib txawv hauv cov kab ke kom tshem tawm polishing residues, roj thiab hais. Thaum kawg, lawv tau yaug nrog dej ultrapure thiab kho mob - qib cawv, thiab tam sim ntawd qhuav kom huv si nrog lim dej kub kom tsis txhob muaj dej stains.

Theem V: Hub los ua ke thiab Qhov kawg Sterilization

11. Hub Moulding thiab Precision Assembly

hubs (feem ntau yog ua los ntawm kev kho mob polycarbonate, ABS, thiab lwm yam) yog molded nyob rau hauv ib tug sterile txhaj molding rhiav. Tom qab ntawd, ntawm ib qho ultra- huv workbench, cov txheej txheem koob raj thiab lub hub tau raug sib sau ua ke los ntawm cov cuab yeej siv hluav taws xob siv laser vuam, kev kho mob cov nplaum nplaum los yog cuam tshuam, kom ntseeg tau tias muaj zog coaxiality thiab kev sib txuas zoo heev.

12. 100% Kev tshuaj xyuas tag nrho thiab kev tswj xyuas txheej txheem

Thaum lub sij hawm tsim cov txheej txheem, ntawm -kab soj ntsuam kab ntsuas qhov ntev ntawm lub sijhawm. Cov koob tiav lawm yuav tsum tau kuaj xyuas 100%, suav nrog kev ntsuas qhov tob tob tob ( ntsuas qhov sib tsoo quab yuam nrog cov qauv silicone ntawv), patency test (dej flow test), kev sib txuas firmness test, rigidity test thiab pom kev nyob rau hauv lub tshuab ntsuas.

13. Terminal Sterilization thiab ntim

Cov khoom no yog sterilized los ntawm nruj validated ethylene oxide (EtO) sterilization los yog gamma ray irradiation kom tsis muaj menyuam. Tom qab ua kom tsis muaj menyuam, lawv raug kaw tam sim ntawd hauv lub hnab ntim khoom ua los ntawm cov khoom siv microbial barrier xws li Tyvek nyob rau hauv aseptic mob. Txhua pob yuav tsum xeem dhau qhov kev xeem kom tsis muaj menyuam.

Xaus

Kev hloov pauv los ntawm lub raj hlau mus rau qhov tsim nyog koob kho mob uas cawm tau txoj sia sawv cev rau qhov ua tiav ntawm cov txheej txheem niaj hnub precision manufacturing technologies. Nws integrates cov ntaub ntawv science, precision mechanical processing, electrochemistry, ultrasonic technology, aseptic ntim tshuab thiab strictest zoo tswj systems. Tom qab txhua rab koob muaj ntau pua tus txheej txheem ua tiav thiab suav tsis txheeb qhov chaw kuaj xyuas zoo, tag nrho rau ib lub hom phiaj: ua tiav xoom- tsis zoo ua haujlwm zoo thaum lub sijhawm nkag mus rau tib neeg lub cev. Qhov no yog qhov zoo tshaj plaws embodiment ntawm "ingenuity" thiab "technology" nyob rau hauv cov khoom siv kho mob manufacturing kev lag luam.
