Los ntawm cov cuab yeej mus rau cov txheej txheem-Cov kev soj ntsuam logic ntawm koob cov ntaub ntawv xaiv nyob rau hauv lub mis Biopsy

https://www.mayoclinic.org/tests-procedures/breast-biopsy/about/pac-20384812

Hauvlub mis biopsycov txheej txheem, rab koob tsis yog tsuas yog ib qho cuab yeej rau kev tau txais cov ntaub so ntswg kuaj tab sis kuj yog ib qho tseem ceeb sib txawv ntawm kev txiav txim siab qhov tseeb thiab kev nyab xeeb ntawm kev ua haujlwm. Nrog rau kev nce ntxiv ntawm kev kho mob tsawg kawg nkaus, lub mis biopsy tau dhau los ua txoj kev nyiam rau kev sib txawv ntawm cov kab mob benign thiab malignant. Kev xaiv ntawm cov khoom siv koob ncaj qha cuam tshuam rau cov qauv kev ncaj ncees, tus neeg mob kev nplij siab, thiab qhov tshwm sim ntawm cov teeb meem tom qab phais.

Tam sim no, cov ntaub ntawv tseem ceeb ntawm lub mis biopsy koob siv kho mob poob rau hauv peb pawg tseem ceeb: stainless hlau, titanium alloy, thiab kho mob- qib polymers. Txhua yam khoom muaj nws qhov kev thov tshwj xeeb thiab qhov zoo / qhov tsis zoo.

Stainless hlau: Ib qho kev xaiv Classic, muaj zog thiab ntseeg tau

Stainless hlau, vim nws zoo heev txhua yam muaj zog, corrosion kuj, thiab biocompatibility, tau ntev lawm cov khoom nyiam rau reusable koob. Nyob rau hauv cov txheej txheem biopsy ntawm lub mis, cov koob stainless hlau muaj qhov zoo rigidity thiab sharpness tuav, ua rau lawv tshwj xeeb tshaj yog haum rau cov xwm txheej uas yuav tsum tau ntau punctures los yog sampling ntawm cov ntaub so ntswg nyuaj. Lawv cov nqi kuj tseem tswj tau, lawv yooj yim los tua kab mob thiab rov siv dua hauv tsev kho mob, thiab lawv ua raws li cov txheej txheem kho mob ib txwm muaj. However, stainless steel has a high density, which may increase hand fatigue for doctors during prolonged operation; Tsis tas li ntawd, kev ua kom tsis muaj menyuam tsis tiav ua rau muaj kev pheej hmoo ntawm kev sib kis -. Yog li ntawd, niaj hnub no txoj kev nce zuj zus mus rau ib leeg - siv, nws daim ntawv thov tau maj mam txo qis rau qee qhov xwm txheej.

Titanium Alloy: Lub teeb yuag, siab -Performance Rising Force

Titanium alloys, nrog lub zog nce mus txog ntawm cov hlau tsis muaj steel tab sis hnyav tsuas yog 60% ntawm nws, tab tom tau txais kev tuav pov hwm hauv siab - kawg ntawm lub mis biopsy cov txheej txheem. Lawv superior corrosion kuj tsis tsuas yog ncua sij hawm ntsuas lub neej tab sis, tseem ceeb tshaj, txo qhov kev pheej hmoo ntawm hlau ion tso rau hauv tus neeg mob lub cev, txhim kho biosafety. Rau stereotactic lossis MRI-kev coj noj coj ua uas xav tau siab- qhov tseeb qhov chaw thiab ua haujlwm ntev, titanium alloy puncture koob zoo txo ​​tus kws kho mob cov haujlwm thiab txhim kho cov lus pom zoo. Txawm hais tias tus nqi siab dua, nws tus nqi -kev ua tau zoo yog rov qab los- soj ntsuam nyob rau hauv ib puag ncig kev kho mob niaj hnub uas yog qhov tseem ceeb ntawm kev ua haujlwm siab tshaj plaws thiab kev nyab xeeb ntawm tus neeg mob.

Kev Kho Mob Polymers: Ib qho Kev Ntsuas Kev Nyab Xeeb rau Ib Leeg -Siv Era

Nrog rau cov kev xav tau nce ntxiv rau kev tswj hwm kab mob hauv tsev kho mob, "ib zaug-siv" tau dhau los ua ib qho tseem ceeb hauv cov txheej txheem biopsy ntawm lub mis. Kev kho mob- qib plastics lossis polymers (xws li polycarbonate thiab PEEK) tshem tawm tag nrho cov kev pheej hmoo ntawm kev hla- kis kab mob thiab tshem tawm qhov xav tau ntawm cov txheej txheem ntxuav thiab tshuaj tua kab mob, txhim kho kev ua haujlwm zoo heev. Cov ntaub ntawv no feem ntau yog pob tshab, ua kom yooj yim rau kev soj ntsuam cov ntshav rov qab los yog cov ntaub so ntswg txhaws; lawv cov kev ntxhib los mos kuj txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov hlab ntsha thiab cov hlab ntsha. However, their lower rigidity makes them unsuitable for extremely dense fibrotic breast tissue, and they are prone to deformation under high-temperature, high-pressure sterilization, therefore strictly limited to single-use.

Kev xaiv cov ntaub ntawv cuam tshuam li cas rau txoj kev biopsy?

Nyob rau hauv cov txheej txheem biopsy ntawm lub mis tiag tiag, kev xaiv cov khoom siv yuav tsum ua tib zoo xav txog qhov xwm txheej ntawm qhov txhab, cov txheej txheem kev coj ua, thiab qhov sib txawv ntawm tus neeg mob. Piv txwv li, rau qhov chaw biopsies ntawm qhov sib sib zog nqus, me me calcifications, lub teeb yuag ntawm titanium alloy koob pab txhim kho maneuver precision; Thaum lub sij hawm aspiration ntawm cov hlwv nyob sab nraud, qhov yooj ntawm cov koob tshuaj polymer yog qhov zoo dua. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tsis hais txog ntawm cov khoom siv, lub koob tip tsim yuav tsum yog ergonomically tsim los txo cov ntaub so ntswg tearing thiab xyuas kom meej cov qauv kev ncaj ncees.

Nyob rau hauv lub neej yav tom ntej, nrog rau kev loj hlob ntawm cov khoom siv technology, tshiab puncture koob combining lub zog ntawm hlau thiab lub biocompatibility ntawm polymers yuav ntxiv revolutionize lub mis biopsy cov txheej txheem. Thaum txiav txim siab txog kev yuav khoom, cov tsev kho mob yuav tsum txav mus dhau qhov kev sib piv tus nqi yooj yim thiab ntsuas los ntawm ntau qhov ntev, suav nrog tag nrho lub neej- tus nqi ntawm lub voj voog, cov txiaj ntsig kev tiv thaiv kab mob, thiab kev kho mob tau zoo, thaum kawg ua rau cov neeg mob tau txais txiaj ntsig zoo tshaj plaws.
