Stereotacticlub mis biopsyTam sim no yog ib txoj hauv kev tseem ceeb rau kev kuaj mob tsis yog -palpable me me qhov txhab, tshwj xeeb tshaj yog tsim rau microcalcifications thiab cov kab mob sib txawv uas pom tau los ntawm mammography. Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv nws "kev pom, qhov tseeb, thiab kev raug mob tsawg heev," uas tso siab rau kev sib koom tes ntawm kev siv lub siab -txoj kev ntsuas qhov tseeb thiab rab koob tshwj xeeb.

I. Imaging Basis ntawm Stereotactic Technology

Stereotactic systems feem ntau siv digital mammography (DBT) lossis cov khoom siv mammography ib txwm muaj kom tau txais cov duab los ntawm ob qhov sib txawv (feem ntau ± 15 degree) los tsim peb - qhov chaw ntawm qhov chaw ntawm qhov txhab. Lub khoos phis tawj txiav txim siab txog qhov nkag ntawm daim tawv nqaij, qhov tob tob, thiab lub kaum ntse ntse, coj cov koob tshuaj biopsy kom meej rau thaj chaw lub hom phiaj. Piv nrog rau ultrasound-kev coj noj coj ua, kev siv tshuab stereotactic yog qhov tsim nyog rau lub mis tuab thiab cov kab mob thaum ntxov uas tsuas yog tshwm sim raws li calcifications.

II. Cov qauv thiab cov ntsiab lus tseem ceeb ntawm Biopsy koob

Nyob rau hauv cov txheej txheem no, lub mis biopsy koob tsis yog tsuas yog ib qho piv txwv tab sis kuj yog ib qho tseem ceeb consumable txiav txim siab qhov tseeb ntawm kev kuaj mob.

- Ntev: Nyob ntawm lub mis tuab thiab tus neeg mob txoj hauj lwm, qhov ntev siv feem ntau yog 5-10 cm. luv luv ib rab koob yuav tsis ncav cuag cov kab mob sib sib zog nqus, thaum ntev ntev ib rab koob yuav ua rau muaj kev pheej hmoo ntawm cov ntaub so ntswg puas.

- Diameter (Gauge): Clinically, 14G, 16G, thiab 18G feem ntau siv. Ntawm lawv, 14G yog qhov kev xav tau tshwj xeeb rau stereotactic biopsy vim nws cov ntaub so ntswg txaus thiab cov teeb meem tswj tau. Nws yog ib qho tsim nyog sau cia tias qhov ntsuas me me ntawm tus nqi, qhov loj ntawm lub taub sab nraud ntawm rab koob, thiab qhov kev ua haujlwm zoo dua qub, tab sis qhov kev pheej hmoo ntawm kev puas tsuaj rau cov ducts mammary thiab cov hlab ntsha kuj nce ntxiv.

- Koob Tip Design: Ib rab koob beveled los yog daim duab peb sab yuav pab txo tau qhov mob thiab txhim kho tus neeg mob kev nplij siab.

III. Kev sib piv ntawm Mainstream Khoom yam ntxwv

Khoom siv|Yam ntxwv|Siv tau Scenarios

Stainless hlau|Siab zog, corrosion kuj, nruab nrab nqi|Reusable biopsy rab koob

Titanium Alloy|Tsawg ceev, hnav, zoo biocompatibility|High -koob pov tseg biopsy koob

Cov ntaub ntawv kho mob Polymer|Tsis muaj hlau artifacts, kiag li pov tseg|Kev tshawb fawb siv los yog kev tshuaj ntsuam xyuas tshwj xeeb

Hauv stereotactic biopsy, stainless hlau tseem yog qhov kev xaiv tseem ceeb, tab sis titanium alloy koob tau maj mam nce qib hauv qhov tseeb qhov xwm txheej vim lawv qhov hnyav thiab kev tuav zoo.

IV. Cov cuab yeej sib koom ua ke thaum ua haujlwm

Ib qho kev ua tiav stereotactic puncture yuav tsum muaj kev sib koom tes siab ntawm cov koob tshuaj biopsy, daim phiaj txoj haujlwm, cov phaj compression, thiab cov duab kos duab. Tom qab kaw qhov kev sib koom ua ke, tus kws kho mob tau nce lub koob txhaj tshuaj raws li cov lus qhia groove, siv lub hauv paus ntsiab lus ntawm rab koob txiav kom tau txais cov qauv ntawm cov ntaub so ntswg. Tag nrho cov txheej txheem feem ntau ua tiav nyob rau hauv cov tshuaj loog hauv zos thiab siv sijhawm li 20-30 feeb.

V. Kev txwv thiab kev loj hlob Trends

Txawm hais tias stereotactic biopsy muaj qhov raug siab, nws tseem raug txwv los ntawm ntau yam xws li kev faib tawm ntawm cov calcifications thiab tus neeg mob tsis muaj peev xwm zam lub sijhawm ntev. Nyob rau hauv xyoo tas los no, kev qhia txog lub tshuab nqus tsev-pab biopsy (VAB) cov tshuab tau ua kom cov ntaub so ntswg tau txais ib rab koob thiab txo qis tus nqi tsis zoo. Nyob rau hauv lub neej yav tom ntej, nrog rau kev siv AI- pab txoj kev muab tso rau algorithms thiab tshiab cov ntaub ntawv sib xyaw koob, stereotactic mis biopsy yuav ua tiav kev sib tw ntxiv ntawm qhov raug thiab kev nyab xeeb.
