Kev lag luam Pain PointsIb txwm qhib lub plab nkag mus thiab blunt trocar nkag tau muaj qhov cuam tshuam txog kev cuam tshuam tsawg kawg nkaus. Qhib nkag yuav tsum tau loj lub plab phab ntsa incision, loj kev puas tsuaj rau daim tawv nqaij, fascia thiab cov leeg nqaij txheej, loj intraoperative los ntshav, ntev postoperative rov ua hauj lwm lub sij hawm thiab pom tseeb phais caws pliav, tsis ua raws li cov neeg mob 'xav tau rau minimally invasive thiab sai rehabilitation. Cov tsoos blunt trocar dig muag puncture tsis muaj txheej txheej nkag mus ua haujlwm, uas yooj yim nruj rau hauv- plab hnyuv plab, ua rau plab hnyuv contusion thiab vascular rupture. Cov qauv nruj ib leeg tsis tuaj yeem cuam tshuam qhov quab yuam, ua rau muaj kev puas tsuaj rau lub plab phab ntsa ntau dhau, mob hnyav tom qab phais thiab muaj qhov tshwm sim siab ntawm qhov ua rau adhesion. Tsis tas li ntawd, cov txheej txheem nkag tsis tuaj yeem tsim kom muaj kev ruaj ntseg pneumoperitoneum ua ntej, ua rau pom kev phais nqaim, kev ua haujlwm nyuaj tom qab thiab kev phais mob ntxiv, uas txwv tsis pub muaj kev nrov nrov thiab txhim kho kev phais laparoscopic tsawg kawg nkaus.

Txoj Cai Ua HaujlwmLub hauv paus ntsiab lus tsawg tsawg ntawm Veress koob nkag cov txheej txheem yog txheej txheem nkag mus thiab tsis muaj kev nyab xeeb nkag, paub txog cov ntaub so ntswg tsawg tsawg los ntawm cov qauv tsim kho tshiab thiab kev ua haujlwm zoo. Cov qauv tapered conical slender cannula qauv ntawm Veress koob paub gradual tho ntawm daim tawv nqaij, cov ntaub so ntswg subcutaneous, plab fascia thiab peritoneum txheej los ntawm txheej, tsis txhob nruj extrusion thiab tearing ntawm tsoos blunt instruments rau plab phab ntsa ntaub so ntswg. Kev tsim- nyob rau hauv lub caij nplooj ntoos hlav tiv thaiv txheej txheem yog tus yuam sij rau kev nyab xeeb tsawg kawg nkaus: lub ntsej muag rab koob ntse nkag mus rau phab ntsa plab, thiab cov blunt puab cores cia li tshwm sim tom qab nkag mus rau qhov qis -siab plab kab noj hniav, npog cov koob ntse ntse kom tiv thaiv khawb intra- plab thiab cov hlab ntsha hauv plab. Through the tiny lumen, low-flow uniform carbon dioxide is injected in advance to lift the abdominal wall, form a safe operation space, separate visceral organs from the abdominal wall, and avoid secondary injury caused by subsequent trocar placement. Tag nrho cov txheej txheem nkag tau paub meej, tswj tau thiab buffered tsawg kawg nkaus kev raug mob, uas yog txawv kiag li ntawm qhov kev puas tsuaj loj ntawm cov txheej txheem nkag.

Kev faib khoom sivRaws li minimally invasive qauv tsim thiab kev tiv thaiv kev ua tau zoo,Veress koobmuab faib ua peb hom kev. Ua ntej, yooj yim minimally invasive Veress koob, nrog cov qauv tapered cannula thiab cov qauv kev tiv thaiv lub caij nplooj ntoos hlav, haum rau niaj hnub kev phais laparoscopic tsis yooj yim, paub txog qhov kev raug mob tsawg thiab kev nyab xeeb, nrog rau kev ua haujlwm siab. Qhov thib ob, txhim kho cov koob Veress tsawg kawg nkaus, nrog kev ua kom zoo tshaj plaws ultra- cov lus sib dhos zoo thiab txhim kho lub caij nplooj ntoo hlav tsis zoo, qhov kev txiav me me thiab lub zog nkag mus rau softer, tsim nyog rau kev phais cov ntaub so ntswg thiab cov xwm txheej uas yuav tsum tau ua kom zoo nkauj, nrog cov nyhuv me me zoo dua. Thib peb, siab -kev nyab xeeb tiv thaiv Veress koob, nrog dual tiv thaiv -txoj kev thiab tiv thaiv- cov qauv khawb, txhim kho lub siab thiab ruaj khov, tshwj xeeb tshaj yog siv rau cov kev phais nyuaj xws li plab adhesion, rov phais dua thiab kev phais neeg mob rog, ua kom tsis txhob muaj kev raug mob visceral.

Phau Ntawv Qhia Txog Kev Ua HaujlwmTxhawm rau kom ua tiav qhov zoo tshaj plaws ntawm qhov tsis txaus ntseeg ntawm Veress koob nkag cov txheej txheem, cov txheej txheem ua haujlwm qis - raug mob yuav tsum ua raws. Ua ntej ua haujlwm, xaiv qhov sib piv cov koob txhaj tshuaj tsawg kawg nkaus raws li kev phais mob nyuaj thiab tus neeg mob lub cev, thiab ua rau cov kab mob me me me me dua li rab koob txheej kab uas hla kom nruj nruj thiab raug mob tsawg. Intraoperatively, txais yuav qeeb cov kev quab yuam kev nce qib kom paub txog txheej txheej nkag mus ntawm lub plab phab ntsa ntaub so ntswg, hnov ​​​​txog ob qhov kev xav ntawm fascia thiab peritoneum nyob rau hauv lem, thiab tsis txhob nce mus sai sai tom qab qhov thib ob breakthrough kom tsis txhob muaj qhov tob tob. Tom qab cov tub ntxhais sab hauv pops tuaj yeem, paub meej tias qhov kev nyab xeeb intraperitoneal txoj haujlwm los ntawm kev ntsuas kev poob qis thiab kev ntsuas siab. Txais yuav tsawg- ntws thiab qis- siab graded gas txhaj tshuaj, maj mam nthuav lub plab kab noj hniav, tsis txhob ceev ceev siab - cov pa roj txhaj ua rau visceral compression raug mob. Tom qab ua tiav kev tsim pneumoperitoneum, tshem lub koob maj mam raws tus thawj txoj kev kom tsis txhob muaj cov ntaub so ntswg tearing, paub txog tag nrho cov txheej txheem ntawm kev nkag mus tsawg tsawg.

Kev paub txog kev lag luamCov ntaub ntawv kho mob tsawg kawg nkaus ua rau pom tau tias Veress koob nkag cov txheej txheem txo cov kab mob plab phab ntsa puas los ntawm ntau dua 80% piv nrog cov tsoos qhib nkag, thiab txo qis qhov mob tom qab phais thiab qhov chaw caws pliav loj heev. Lub caij nplooj ntoos hlav tsis siv neeg tiv thaiv qauv ua tiav xoom ntse khawb kev raug mob ntawm intra- plab hnyuv siab raum hauv kev ua haujlwm tau zoo, txhim kho kev phais kev nyab xeeb zoo heev. Ua ntej-pneumoperitoneum tsim tau zoo cais cov phab ntsa hauv plab thiab lub qhov ncauj, zam kev raug mob trocar extrusion, thiab txo qhov tshwm sim ntawm cov teeb meem intraoperative ntau dua 60%. Qhov me me incision nkag hom paub qhov mob sai sai, txo cov neeg mob tom qab lub sijhawm mus pw hauv tsev kho mob li 1-2 hnub, thiab txhim kho kev kho mob sai sai. Txhim kho cov koob txhaj tshuaj me me qhia tau zoo dua cov tshuaj pleev ib ce thiab kho kom zoo nkauj hauv cov tshuaj pleev ib ce minimally invasive phais thiab cov tub ntxhais hluas cov neeg mob phais, uas tau lees paub dav hauv kev kho mob.

Summary thiab SublimationVeress koob nkag cov txheej txheem sawv cev rau qhov kev nkag mus tau yooj yim siv thev naus laus zis ntawm kev phais laparoscopic niaj hnub, ua kom tshem tawm cov kev raug mob loj heev ntawm cov txheej txheem qhib thiab blunt nkag. Relying ntawm lub txheej txheej txheej nkag mus rau lub caij nplooj ntoos hlav thiab lub caij nplooj ntoos hlav tiv thaiv kev ruaj ntseg tsim, nws paub txog cov organic sib koom ua ke ntawm tsawg kawg nkaus kev raug mob, kev ua hauj lwm muaj kev ruaj ntseg thiab sai sai postoperative rehabilitation. Lub hierarchical minimally invasive khoom system npog cov xwm txheej niaj hnub thiab kev phais mob, ua tau raws li qhov sib txawv me me invasive thiab siab -kev nyab xeeb xav tau ntawm kev phais kho mob niaj hnub no. Raws li cov tub ntxhais nkag tshuab ntawm laparoscopic minimally invasive phais, nws tsis tsuas yog txhim kho kev phais mob, tab sis kuj txhawb kev hloov pauv ntawm kev phais plab los ntawm kev qhib kev raug mob mus rau qhov kev cuam tshuam tsawg heev, ua rau txoj kev loj hlob ntawm kev phais me me niaj hnub no.

Cov lus qhia txog kev txhim kho yav tom ntejYav tom ntej minimally invasive technology upgrading of Veress entry will focus on ultra-invasion minimal invasion and intelligent protection. Ua ntej, ua kom zoo dua ntawm rab koob tip taper tsim kom paub txog ultra- txheej txheej nkag mus zoo thiab txo qis plab phab ntsa incision. Thib ob, txhim kho qhov ntse lub caij nplooj ntoos hlav sensing qauv, paub qhov tob tsis siv neeg ceeb toom ntxov thiab kev tiv thaiv overload, thiab txhim kho kev nyab xeeb kev ua haujlwm. Thib peb, ua kom zoo dua cov roj txhaj tshuaj lumen kom paub ntau yam zoo thiab ruaj khov pneumoperitoneum tsim thiab txo cov visceral siab fluctuation. Thib plaub, sau cov kev paub ua haujlwm tsawg kawg nkaus los tsim cov txheej txheem ua haujlwm kom zoo, ntxiv cov txheej txheem tag nrho - txheej txheem kev ua haujlwm tsawg kawg nkaus ntawm Veress nkag cov txheej txheem, thiab txhawb kev nthuav dav dav ntawm qib siab -tus qauv kev nkag mus rau hauv plab me me.
