Lub evolution ntawm lublub mis biopsy koobyog keeb kwm ntawm kev tsim kho tshiab txuas ntxiv uas tau tsav los ntawm kev nrhiav kev siab dua, kev raug mob qis dua, thiab txhim kho kev ua haujlwm. Los ntawm phau ntawv txiav mus rau kev pab lub tshuab nqus tsev, thiab los ntawm cov qauv yooj yim mus rau kev kuaj mob sib xyaw, koob tshuab tau nce mus rau kev txawj ntse, miniaturization, thiab multifunctionality.

Thawj Tiam: Tus Leap ntawm Phau Ntawv rau Tsis Siv Neeg

Thaum ntxov biopsies tso siab rau kev phais qhib lossis phau ntawv txiav, uas tau cuam tshuam nrog kev raug mob siab thiab tsis muaj qhov tseeb. Lub advent ntawm lub caij nplooj ntoos hlav- loaded tsis siv neeg biopsy rab phom nyob rau hauv lub xyoo 1980s tso cai rau cov stylet nkag mus rau cov ntaub so ntswg ntawm tsis tshua muaj siab ceev, ua tiav cov txheej txheem txiav thiab retrieval instantaneously. Qhov no tau txhim kho cov qauv zoo thiab cov neeg mob tolerability. Tom qab ntawd, qhov tshwm sim ntawm Lub Tshuab Nqus Tsev-Assisted Biopsy (VAB) systems tau kos npe rau lwm qhov kev hloov pauv: siv lub siab tsis zoo txuas ntxiv mus rub cov ntaub so ntswg rau hauv qhov chaw nres nkoj sab ua ntej kev txiav, cov tshuab no tuaj yeem sau ntau cov qauv sib txuas nrog ib qho kev ntxig. Qhov no ua rau lawv tshwj xeeb tshaj yog tsim nyog rau cov txheej txheem minimally invasive excisional aimed ntawm tshem tawm cov duab txawv txav kiag li.

Thib Ob Tiam: Duab Fusion thiab Navigation Technology

Tam sim no cov thev naus laus zis hotspots tsom mus rau kev sib sib zog nqus ntawm cov koob tshuaj biopsy nrog cov duab siab heev -kev taw qhia. Piv txwv li, electromagnetic navigation systems yuav haum nrog me me sensors ntawm lub koob, qhia nws tiag - lub sij hawm txoj hauj lwm nyob rau hauv 3D qhov chaw overlaid rau ua ntej -operative MRI los yog PET- CT duab, ua rau "qhov koj pom yog dab tsi koj tau txais" precision targeting. Qhov no yog tshwj xeeb tshaj yog zoo rau cov kab mob nyob sib sib zog nqus nyob rau hauv lub mis, nyob ib sab ntawm lub hauv siab phab ntsa, los yog nrog irregular morphology. Tsis tas li ntawd, photoacoustic imaging thev naus laus zis tab tom tshawb nrhiav rau kev koom ua ke rau hauv koob; los ntawm kev siv laser-induced ultrasound los muab lub sijhawm tiag tiag - tawm tswv yim ntawm cov tsis xws li cov ntshav oxygen saturation thiab collagen cov ntsiab lus nyob ib ncig ntawm rab koob, nws pab kom paub qhov txawv ntawm cov qog nqaij hlav ntawm cov nqaij mos.

Thib Peb: Kev Txawj Ntse thiab Molecular Sensing

Cov koob tshuaj biopsy yav tom ntej tuaj yeem muaj peev xwm "kev nkag siab". Cov kws tshawb nrhiav tab tom tsim cov koob nrog micro-spectrometers lossis Raman sojntsuam muaj peev xwm txheeb xyuas cov ntaub so ntswg spectral ntiv tes tiag tiag- lub sijhawm thaum lub sijhawm nkag mus rau qhov ua ntej txiav txim siab muaj cov qog nqaij hlav cancer- ua tiav "kev kuaj mob- ntawm -- mus." Mus ntxiv, rab koob nto tuaj yeem hloov kho nrog cov tshuaj tiv thaiv tshwj xeeb lossis nucleic acid aptamers uas tsim cov fluorescence lossis electrochemical signals thaum sib cuag nrog cov qog hlwb, ntes microscopic molecular anomalies txawm ua ntej macroscopic kev hloov pauv tshwm sim. Qhov no "smart needle" cog lus tias yuav txhim kho biopsies los ntawm cov qauv passive mus rau kev tshawb nrhiav nquag.

Plaub tiam: Kev koom ua ke ntawm kev kho mob thiab kev kuaj mob

"Theragnostics" (Kev Kho Mob + Diagnostics) sawv cev rau lwm qhov kev taw qhia loj. Thaum tau txais cov ntaub so ntswg, rab koob tuaj yeem xa cov tshuaj loog hauv zos, cov neeg ua haujlwm hemostatic, lossis cov kab mob radioactive (xws li cov siv rau cov qog nqaij hlav qog nqaij hlav). Hauv qee qhov kev tsim, koob nws tus kheej ua raws li ablation electrode; raws li kev lees paub qhov kev ua tau zoo, nws tuaj yeem ua tau tam sim radiofrequency lossis cryoablation ntawm cov kab mob me me, ua tiav "kev kuaj mob thiab kev kho mob hauv ib zaug" thiab txo qhov kev xav tau rov mus xyuas hauv tsev kho mob. Lub tswv yim no tshwj xeeb tshaj yog siv tau rau kev kho mob tsawg kawg nkaus rau kev mob qog noj ntshav thaum ntxov -.

Txawm hais tias muaj kev cia siab zoo, cov thev naus laus zis tshiab no yuav tsum kov yeej cov teeb meem xws li cov nqi siab, nce kev ua haujlwm nyuaj, thiab cov txheej txheem kev pom zoo nruj. Saib tom ntej, nrog rau kev nce qib ntawm Micro-Electro-Mechanical Systems (MEMS) thiab nanotechnology, peb muaj txhua qhov laj thawj los ntseeg tias koob txhaj tshuaj ntawm lub mis yuav hloov zuj zus los ntawm ib qho "sampling tool" mus rau hauv lub platform ntse sib koom ua ke kev kuaj mob, saib xyuas, thiab kev kho mob, ua rau kev tswj mob qog noj ntshav ntawm tus kheej ntau dua.
