Dab tsi yog qhov rov pib dua (Cocking / Loading) Kev Ua Haujlwm Ntawm Lub Mis Biopsy Koob

Cov Ntsiab Cai thiab Cov Txheej Txheem Ua Haujlwm rau Semi - Tsis Siv Neeg thiab Tsis Siv Neeg Siv Tshuaj Siv Tshuaj Txhuam

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

Hauv minimally invasivekuaj mob lub mis-txawm yog Ultrasound-Guided Core Needle Biopsy (CNB) lossis Stereotactic/Vacuum-Assisted Biopsy (VAB)-the"Reset" lossis "Cocking" (Loading) ua haujlwmyog lub hauv paus, rov ua dua. Tsuas yog muab tso rau, tom qab lub tshuab biopsy tua hluav taws thiab txiav cov ntaub so ntswg, cov txheej txheem rov pib siv phau ntawv lossis hluav taws xob txhais tau tias rov- compress lub caij nplooj ntoos hlav firing(s), thim rov qab cov stylet sab hauv kom nthuav tawm cov qauv notch, thiab tshem tawm sab nraud txiav cannula rau nws qhov chaw pib muaj kev nyab xeeb. Qhov no xa rov qab cov cuab yeej mus rau "npaj-rau-hluav taws" xeev. Nws tsis yog tsuas yog ib qho khoom siv rov qab; nws yog qhov yuav tsum tau ua ua ntej rau tus qauv ua tau zoo tom ntej thiab rau kev nyab xeeb ntawm tus neeg mob.

1. Dual-Action Reset Mechanism of Semi- Tsis Siv Neeg Biopsy Koob

Qhov feem ntau siv semi-automatic core biopsy koob siv ib tug precision dual- caij nplooj ntoos hlav firing system. Cov txheej txheem rov pib dua yog qhov txawv ntawm ob -theem:

• Thawj rub (Stylet Retraction / Cocking):Tus neeg teb xov tooj rub rov qab rov qab tua swb / pas nrig kom txog thaum pom tseeb"nias"hnov thiab hnov. Qhov no compresses lub caij nplooj ntoos hlav puab thiab retracts lub puab stylet, tag nrho exposing lubsampling notch (cov ntaub so ntswg groove)sab nraum lub cannula sab nraud.Qhov no yog qhov tseem ceeb rov pib dua theem.Kev ua tsis tiav ntawm kev rub tag nrho ua rau "qhov hluav taws kub dawb paug" (qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khawm).
• Kev tua hluav taws:Nrog rau qhov kev ceeb toom nthuav tawm thiab tso rau hauv lub hom phiaj, tus txhais tau nyem. Lub puab stylet pops rau pem hauv ntej rau thauj tog rau nkoj cov ntaub so ntswg, ua raws li tam sim ntawd los ntawm lub sab nrauv cannula tsav los ntawm lub thib ob caij nplooj ntoos hlav, uas severs lub core.
• Rov pib dua thib ob (Cycle Preparation):​ Tshaj tawm - txiav, qhov hluav taws xob swb yuav tsum tau rub rov qab los rau re- compress springs, tshem tawm cov cannula sab nraud, thiab rov- nthuav tawm qhov thais rau qhov dhau mus. Hauvtxheej txheem coaxial, cov txheej txheem qhia tawm sab nraud tseem nyobhauv qhov; tsuas yog cov stylet sab hauv- koob yog rho tawm, rov pib dua, thiab rov ua dua los ntawm lub plhaub rau ntau cov qauv ntawm ib qho tawv nqaij.

2. Push-Ntaub Reset of Fully Automatic Disposable Biopsy Needles

Cov koob txhaj tshuaj tsis siv neeg puv puv ua kom yooj yim rau qhov kev txiav txim nrog ob qhov sib txawv cocking nyees khawm. Tom qab tua hluav taws, ob sab hauv stylet thiab sab nrauv cannula tseem txuas ntxiv. Rov pib dua yuav tsum tau ua kom ua ntu zus:

• Nias lubSab nrauv Cannula Cocking Khawm→ Lub raj sab nraud rov qab mus rau qhov chaw pib.
• Nias lubSab hauv Stylet Cocking Khawm→ puab stylet retracts, exposing lub thais.
• Ob qhov tseeb "nias" qhia tau hais tias rov pib dua. Qhov kev tsim no txo ​​qis kev tuav tes rub quab yuam thiab txo qis qis dua - ua tsis tiav vim yog tes qaug zog.

3. Electronic "homing / Initialization" hauv Nqus Tsev-Assisted Biopsy (VAB) Systems

Rau VAB systems (piv txwv li, Mammotome®, ATEC®), "reset" encompasses electronic initialization. Tom qab kev sojntsuam ntxig rau hauv lub tes tsho, lub kaw lus muaj zog thiab ua haujlwmHoming / Initialization​ sequence- lub cev muaj zog tsav lub tshuab txiav tawm mus rau qhov kaw - qhov chaw hauv tsev. Qhov no yog lub tshuab hluav taws xob rov pib dua. Nyob nruab nrab ntawm cov qauv, lub cutter txiav retracts (Recocking) tom qab txhua txiav. Ua ntej kev sojntsuam tshem tawm, lub"Retract / Tsev"tus yuam sij yuav tsum tau nias kom paub meej tias lub tshuab txiav tau raug tshem tawm tag nrho hauv cov lus tiv thaivua ntejtshem tawm, tiv thaiv inadvertent laceration ntawm lub mis cov ntaub so ntswg los yog pectoral leeg.

4. Cov ntsiab lus ntawm tus qauv pib dua SOP

Txawm li cas los xij ntawm cov cuab yeej siv, kev rov pib tsim nyog suav nrog:

• Positive Locking Sensation:​Audible "nias" THIAB tactile poob hauv kev tiv thaiv paub meej tias kev koom tes ua tiav.
• Visual Confirmation:Thaum twg ua tau, visually txheeb xyuas qhov sampling notch yognthuav tawm tag nrhothiab sab nraud cannula yog tag nrho retracted.
• Positional Stability:Tshwj tsis yog hloov qhov tob / lub kaum sab xis, tswj cov koob taw qhia hauv cov ntaub so ntswg thaum rov pib dua kom tsis txhob raug mob.

Hauv cov ntsiab lus, qhov rov pib ua haujlwm yog tus choj ntawm cov qauv siv tau zoo. Kev nkag siab txog nws lub hauv paus kev siv tshuab thiab ua raws li cov txheej txheem rov pib dua cov txheej txheem ncaj qha txo qis - cov nqi tseem ceeb, txhim kho cov txiaj ntsig kev kuaj mob, thiab tiv thaiv tus neeg mob. Cov neeg ua haujlwm tshiab yuav tsum xyaum rov pib xav txog kev simulation phantoms kom txog thaum nws dhau los ua cov leeg nqaij.
