Ultrasound Echogenicity Enhancement Technology Rau EBUS -TBNA Koob

Vim li cas Laser-Etched Texturing yog qhov tseem ceeb rau kev nyab xeeb thiab meej Ultrasound kev taw qhia

EBUS (convex sojntsuam, feem ntau 7.5 MHz los yog 5-12 MHz variable zaus) ua kom muaj tseeb -lub sij hawm intraoperative visualization ntawm cov hlab cua phab ntsa, hlab ntsha, lymph nodes, thiab koob txoj hauj lwm. Txawm li cas los xij, cov hlau du nto cuam tshuam txog ultrasound yuav luag tag nrho, tsuas yog ua rau cov plaub hau hyperechoic artifact. Qhov no ua rau pom qhov tseeb ntawm rab koob qhov chaw thiab lub taub hau txoj kev nyuaj-tshwj xeeb tshaj yog thaum punncturing tob lymph nodes los yog thaum lub koob ncej aligns ntawm ntiav kaum rau lub ultrasound beam ("koob taub hau"), elevating txaus ntshai ntawm vascular raug mob los yog dhau - nkag. Yog li ntawd, niaj hnub EBUS-TBNA koob yuav tsum tau tswj qhov chaw micro-structuring kom ua tau raws li kev txhim khu kev qha ultrasound echo li (echogenicity li).

Physical Principple:​ Thaum ultrasound ntsib ib tug hlau nto qauv nrog ib ntus micro-grooves los yog protrusions, nws ua ntau tawg ntho echoes nrog rau specular xav. Cov kab tawg tawg no tshwm sim ntawm B- hom duab raws li qhov dav, ci ntsa iab hyperechoic band piv rau qhov chaw du. Cov neeg ua haujlwm tuaj yeem taug qab qhov ci ntsa iab artifact thiab proximal ncej kawm. Microstructure qhov tob, qhov sib nrug, thiab kev npaj txiav txim siab qhov kev siv zog thiab kev taw qhia- qhov tob tsis txaus ua rau muaj kev txhim kho tsis muaj zog, qhov tob tob ua rau muaj kev ntxhov siab los yog muaj cov kab mob sib kis.

Txoj Kev Ua Haujlwm Tseem Ceeb:

• Laser Etching / Marking:​ Nanosecond/picosecond fiber ntau lasers ablate helical grooves, annular dot matrices, los yog cross-hatched grids mus rau lub koob ncej ze ntawm lub ntsis. Helical grooves muab kev pom zoo ib yam tsis hais txog kev hloov pauv, sawv cev rau cov kev daws teeb meem zoo tshaj plaws rau koob EBUS koob (xws li ViziShot2 series). Tsib -axis lasers ua tiav qhov sib txawv -pitch helices nrog ± 0.01mm precision.
• Micro-Sandblasting + Chemical Etching Combinations:Sandblasting tsim thawj roughness, ua raws li lub zos laser npav rau qhov tob gauging thiab xwm txheej echogenicity. Tus nqi qis dua tab sis tsis sib haum xeeb.
• Echogenic txheej (tsis tshua muaj):​ Plasma-txhaj tshuaj titanium oxide tsim ib qho chaw roughened, tab sis txheej delamination txaus ntshai txwv daim ntawv thov hauv cov khoom siv pov tseg.
• Clinical tseem ceeb:Kev ua haujlwm zoo echogenic cim txhawb cov neeg ua haujlwm kom paub meej: ① kev ua tiav transmural puncture (kev cuam tshuam ntawm cov phab ntsa ci ntsa iab echo los ntawm kev nce qib koob tshuaj tiv thaiv); ② intranodal koob taub txoj hauj lwm (ci ntsa iab artifact encased nyob rau hauv lub hypoechoic lymph node); ③ tsim nyog qhov tob thiab lub kaum sab xis (kwv yees qhov ntev ntawm rab koob hauv cov ntaub so ntswg). Qhov no ua pov thawj tshwj xeeb yog qhov tseem ceeb rau kev ua kom luv luv txoj kev kawm ntawm cov neeg ua haujlwm tshiab thiab tsim cov kauj ruam ua pov thawj pom tseeb thaum lub sijhawm FDA / CE sau npe -feem ntau yuav tsum tau pom qhov pom tseeb ntawm rab koob thiab ntau dua lossis sib npaug li 5 hli ntawm cov ncej hla ntau qhov xwm txheej kaum (30℃/ 45℃/ 60℃/ 90℃} ) tommic cov ntaub so ntswg.

Thaum lub sij hawm yuav khoom, thov cov chaw tsim tshuaj paus -muab ultrasound phantom imaging qhia tus qauv echogenicity yog advisable. Tsom ntsoov rau qhov ntev ntawm thaj chaw cim (feem ntau yog 10-20mm nyob ze ntawm lub ntsis) thiab seb cov lus qhia tau hais meej npaum li cas ultrasound zaus. Tus nqi qis tshaj cov koob uas tsis muaj qhov zoo etching lossis cia siab rau ntawm tus lej cim (uas yog sonolucent) ua rau muaj kev nyab xeeb tseem ceeb thiab tsis tsim nyog rau kev siv tshuaj kho mob.
