Qhov Kev Xav Tau Tshiab Ntawm Txoj Kab Ntsig Tsav Los Ntawm Miniaturization, Kev Txawj Ntse, Thiab Kev Sib Koom Ua Ke

Raws li kev phais me me tau nce mus rau "scarless phais" thiab "single-incision laparoscopy," tus qauv ntawm Veress rab koob tau dhau los ua kev hloov pauv ntsiag to. Txoj kab uas hla, qhov tseem ceeb tshaj plaws ntawm lub cev tsis muaj zog, yog imbued nrog tag nrho cov ntsiab lus tshiab.

Miniaturization Wave: Marching Hauv qab 2 hli

Cov tswv yim pom zoo tau hais tias qhov tsawg kawg nkaus sab nraud txoj kab uas hla (OD) rau Veress koob yog 2.5 hli. Txawm li cas los xij, kev txhim kho tsis ntev los no hauv Laparo-Endoscopic Single-Site (LESS) kev phais thiab Natural Orifice Transluminal Endoscopic Surgery (NOTES) tau ua rau lub tswv yim ntawm "micro-needle." Piv txwv li, Olympus (Nyiv) tau qhia "Nano Veress koob," nrog OD tsuas yog 1.8 hli thiab ID ntawm 1.2 hli, tshwj xeeb tsim rau cov menyuam mos thiab cov menyuam mos yug ntxov. Cov koob no yuav tsum tau siv lub zog me me, tso cai yooj yim phau ntawv nce qib nrog tus ntiv tes, thiab tshem tawm qhov xav tau ntawm suturing tom qab phais. Txawm li cas los xij, nws qhov insufflation flow rate yog qeeb heev, yuav tsum muaj siab -frequency pulse insufflators kom tswj tau qhov kev ua haujlwm zoo. Tsis tas li ntawd, vim yog cov phab ntsa nyias nyias (0.3 hli), cov ntaub ntawv yuav tsum tau hloov kho rau cobalt-chromium alloys lossis nitinol, nce nqi ntau. Nws tau kwv yees tias nyob rau hauv tsib xyoos tom ntej no, Veress koob nrog ODs qis dua 2 hli yuav pom maj mam txais yuav hauv kev phais menyuam yaus thiab kho kom zoo nkauj.

Intelligent Integration: Qhov Kev Sib Tw Diameter rau Sensors thiab Actuators

Tom ntej no - tiam Veress koob tsis yog ib qho yooj yim hlau raj tab sis ib tug multifunctional platform integrating siab sensors, kub sensors, micro- koob yees duab, thiab txawm radiofrequency electrodes. Tag nrho cov khoom no yuav tsum tau ntim rau hauv qhov txwv radial qhov chaw. Piv txwv li, ib tus qauv embeds ib tug MEMS siab nti rau hauv lub koob taub hau bevel los ntsuas cov ntaub so ntswg impedance nyob rau hauv lub sij hawm, qhov txawv ntawm cov rog, nqaij, thiab peritoneum. Lub nti ntsuas tsuas yog 0.5 × 0.5 × 0.2 hli; suav nrog txhuas thiab ntim, tag nrho cov tuab yog tswj kom tsawg dua 0.3 hli, tawm hauv OD tsis hloov. Lwm tus tsim faus cov fibers kho qhov muag nyob rau hauv lub ncej kom paub cov ntshav los yog cov kua tsib ntawm kev tsom xam spectral, ceeb toom tawm tsam qhov tsis raug. Cov khoom siv ntse no muaj kev nkag siab zoo rau cov kev txwv radial -txhua 0.1 hli nce hauv cov khoom tuab tuaj yeem yuam kom nce 0.5 hli hauv OD. Yog li, kev sib tw yav tom ntej yuav nyob hauv "yuav ua li cas koom ua ke cov haujlwm feem ntau hauv 3 hli OD."

Multifunctional Integration: Los ntawm Puncture rau Hemostasis

Kev lig kev cai, Veress koob tsuas yog tsim pneumoperitoneum, tom qab ntawd nws tau pauv rau trocar. Novel "multifunctional Veress koob" lub hom phiaj ua kom tiav ob qho tib si hauv ib kauj ruam: raws li kev ua tiav, lub cev rab koob siv peb lub caj npab, tsim ib qho me me ua hauj lwm channel rau cov twj tso kua mis ncaj qha. Qhov no ua rau cov kev xav tau nruj ntawm txoj kab uas hla- thawj OD yuav tsum tsawg dua lossis sib npaug li 4 hli rau kev nyab xeeb, tab sis qhov nthuav dav sab hauv yuav tsum siab dua lossis sib npaug li 5 hli kom haum rau cov twj paj nruag. Cov kev daws teeb meem suav nrog kev siv cov duab nco alloys (SMA) rau cov pob txha pob txha uas rov ua dua nws cov duab preset thaum hluav taws xob cua sov. Thaum tseem nyob hauv chav kuaj, cov cuab yeej no cog lus tias yuav hloov pauv kev nkag mus rau laparoscopic yog tias matured.

Standardization thiab Personalization Coexisting

Txawm hais tias muaj kev hloov pauv mus rau miniaturization thiab kev txawj ntse, standardization tseem yog lub hauv paus ntawm kev nyab xeeb kev kho mob. Cov qauv thoob ntiaj teb xws li ISO 7151 thiab ASTM F2082 qhia meej meej txog txoj kab uas hla, kev ntsuas qhov ntse, thiab tawg siab ntawm Veress koob. Saib tom ntej, peb yuav pom "modular Veress koob tshuab": cov kws phais tuaj yeem hloov cov koob ntawm cov kab sib txawv (2.5 mm / 3.5 mm / 4.5 mm) ntawm -qhov chaw raws li tus neeg mob lub plab phab ntsa tuab, thaum tus kov thiab cov ntsuas ntsuas nyob twj ywm universal. Qhov kev tsim no khaws cov txheej txheem interfaces thaum ua kom muaj kev xaiv tus kheej.

Xaus

Hauv cov ntsiab lus, evolutionary keeb kwm ntawm Veress koob txoj kab uas hla yog ib tug microcosm ntawm kev kawm nyob rau hauv minimally invasive phais tshuab. Los ntawm ib lub raj hlau yooj yim mus rau cov cuab yeej ntse ua ke nrog kev paub, kev ua haujlwm, thiab kev ntsuas, txhua millimeter txo embodies lub ingenuity ntawm engineers thiab kws phais. Peb muaj txhua qhov laj thawj los ntseeg tias yav tom ntej, Veress koob nrog txoj kab uas hla tsawg dua 2 hli yuav muaj kev nyab xeeb thiab muaj txiaj ntsig qhib lub qhov rooj rau yuav luag txhua cov txheej txheem laparoscopic.
