Lub luag haujlwm tseem ceeb ntawm Kev Kho Mob- Qib 316 Stainless Hlau hauv Precision Biopsy Consumables

Hauv lub ntiaj teb microscopic ntawm kev tsim khoom siv kho mob, kev xaiv cov khoom siv feem ntau hais txog qhov ua tau zoo tshaj plaws thiab kev nyab xeeb ntawm tus neeg mob. RauNqus -Assisted Breast Biopsy (VABB)​​cov koob, uas yuav tsum ua haujlwm siab -load nkaus xws li siab- kev sib hloov ceev, quab yuam txiav, thiab qhov tsis zoo siab aspiration nyob rau hauv complex tib neeg lub cev physiological ib puag ncig, lub cev thiab lom cov khoom ntawm raw cov ntaub ntawv yog nyob rau ze ntawm - cov kev cai nruj. Ntawm ntau yam khoom siv hlau,kho mob -qib 316 stainless hlau (SS316)sawv ua "tus qauv kub" hauv daim teb no vim nws qhov kev ua tau zoo tshaj plaws.

Kev kho mob- qib 316 stainless hlau yog austenitic stainless hlau tshwj xeeb alloyed nrogMolybdenum (hli). Cov ntsiab lus tseem ceeb no ua rau muaj kev tiv thaiv corrosion tsis zoo thiab ua rau cov tshuaj chloride nres. Thaum lub sij hawm biopsy cov txheej txheem, lub koob taub yog nyob rau hauv ntev kev sib cuag nrog tib neeg cov ntaub so ntswg kua, ntshav, thiab lymph- ib puag ncig uas muaj ib tug tseem ceeb electrolyte concentrations. Kev siv cov hlau zoo tib yam yuav ua rau cov cuab yeej raug rau pitting lossis crevice corrosion, ua rau cov hlau ions (xws li npib tsib xee thiab chromium) uas tuaj yeem ua rau lub cev tsis muaj zog lossis mob ntev. Nyob rau hauv sib piv, cov molybdenum nyob rau hauv SS316 pab txoj kev tsim ntawm ib tug ntom, ruaj khov passive zaj duab xis nyob rau hauv steel nto, zoo cais tawm corrosive thiab xyuas kom meej biocompatibility thiab kev nyab xeeb thaum cog. Tsis tas li ntawd, cov khoom muaj ductility zoo heev thiab txhua yam muaj zog, tso cai rau nws rov ua duaautoclaving​ (piv txwv li, siab -kub chav sterilization) yam tsis muaj deformation, yog li lav lub sterile barrier ntawm cov khoom.

Tshaj li tshuaj lom neeg ruaj khov, lub cev thiab lub zog ntawm SS316 yog qhov tseem ceeb sib npaug. Thaum lub sijhawm ua haujlwm, VABB koob yuav tsum nkag mus rau ntawm daim tawv nqaij, cov rog subcutaneous, thiab cov ntaub so ntswg ntawm lub mis. Yog tias rab koob lub cev nruj dhau, kev ua haujlwm nyuaj thiab brittleness nce; Yog hais tias nws yog mos heev, nws yuav txaus ntshai buckling thaum lub sij hawm puncture, ua rau sampling tsis ua hauj lwm los yog puas rau cov ntaub so ntswg. Yog li ntawd, cov qauv kev lag luam nruj me ntsis tswj lub hardness ntawm VABB koob nyob rau hauv lub "golden zone" ntawm70-90 HRB (Rockwell Hardness B Scale). Qhov kev sib tw hardness no ua tiav qhov zoo tshaj plaws txhua yam sib npaug: nws ua kom lub koob ncej tsis tawg nyob rau hauv lub tshuab nqus tsev tsis zoo thaum lav qhov ntse thiab hnav tsis kam ntawm kev txiav ntug. Thaum lub sij hawm siab -kev sib hloov ceev, cov hniav yuav tsum muaj kev ruaj ntseg ntawm ntug heev kom txo qis compression thiab deformation ntawm cov ntaub so ntswg, yog li ua kom muaj siab - cov kab mob zoo. Yuav kom ua tau raws li tus qauv no, cov tuam txhab tsim khoom yuav tsum ua haujlwm siab -kev kos duab txias, kev kho cua sov, thiab cov txheej txheem electropolishing. Txhua rab koob uas tsim nyog muaj peev xwm ua tau zoo ib yam hauv lumen polished rau daim iav tiav kom txo qis kev sib txhuam thaum lub sij hawm kev thauj mus los, thaum lub koob lub kaum sab xis thiab bevel yog precision - hauv av kom ua tau zoo puncture quab yuam thiab cov ntaub so ntswg tsawg heev. Nws tuaj yeem hais tau tias txhua qhov atomic - theem kev kho mob - qib 316 stainless hlau ua haujlwm los tiv thaiv kev nyab xeeb thiab qhov tseeb ntawm kev kho mob phais.
