Laparoscopic tubal oocyte hloov yog ib qho txheej txheem kev phais heev uas vam khom rau kev ua haujlwm zoo. Txhua kauj ruam tus txheej txheem yog ze ze nrog rau qhov kev tso kawm thiab kev siv laparoscopic trocars. Ib qho kev nkag siab hauv - qhov tob tob ntawm cov txheej txheem no qhia tau hais tias cov cuab yeej cuam tshuam tsawg kawg nkaus txhawb nqa cov txheej txheem kev phais kev ua me nyuam me.

Kauj Ruam 1: Tsim Pneumoperitoneum thiab Muab Qhov Chaw Saib Xyuas Chaw Nres Tsheb TrocarTus neeg mob tau muab tso rau hauv txoj hauj lwm Trendelenburg, tso cai rau lub plab hnyuv hloov mus rau sab saud thiab nthuav tawm tag nrho cov kab noj hniav hauv plab. Ib qho 10-millimeter me me incision yog ua nyob rau sab sauv lossis sab ntug ntawm lub umbilicus. Ib rab koob Veress tau muab tso rau hauv lub plab kab noj hniav, thiab cov pa roj carbon dioxide yog insufflated los tsim ib qho pneumoperitoneum ruaj khov. Cov koob Veress yog tom qab ntawd tshem tawm, thiab thawj thiab loj tshaj plaws trocar (feem ntau 10/12 hli) yog ntxig los ntawm tib qhov kev txiav. Ua haujlwm raws li tuschaw nres nkoj tseem ceeb, lub trocar no haum rau lub laparoscope, uas xa cov duab meej ntawm lub plab kab noj hniav mus rau qhov screen zaub kom tiav kev phais navigation thiab qhov chaw.

Kauj Ruam 2: Qhov Chaw Pabcuam Ua Haujlwm Chaw Ua Haujlwm TrocarsRaws li kev pom ncaj qha laparoscopic, 2 mus rau 3 qhov chaw puncture raug xaiv ntawm ob sab ntawm lub plab plab thaum zam cov hlab ntsha . 5-mm trocars feem ntau siv ntawm no. Cov chaw nres nkoj no ua raws li cov ntsiab lus nkag rau cov cuab yeej phais, los ntawm kev siv cov cuab yeej atraumatic forceps, dissecting forceps, suction- dej catheters thiab lwm yam khoom siv tau qhia.

Thaum lub sij hawm hloov tubal oocyte, cov twj paj nruag los ntawm ib qho chaw nres nkoj maj mam tuav thiab nthuav tawm cov mesosalpinx kom stabilize lub ampulla ntawm cov hlab ntsha fallopian. Cov cuab yeej los ntawm lwm qhov chaw nres nkoj tshem tawm me me ntawm effusion lossis ntshav hauv lub plab kab noj hniav kom tswj tau qhov chaw phais kom meej. Lub airtight li qub ntawm lub trocars ua lub luag haujlwm tseem ceeb ntawm theem no: lawv txhawb nqa lub zog pneumoperitoneal ruaj khov thaum lub sij hawm ntsuas ntsuas thiab tshem tawm thiab tiv thaiv kev tawg ntawm kev phais saib.

Kauj Ruam 3: Ua Tubal Oocyte Hloov - Cov Txheej Txheem Txheej TxheemNov yog kauj ruam tseem ceeb ua haujlwm. Lub laparoscope ntawm qhov chaw soj ntsuam tseem ceeb yuav raug hloov nrog tus qauv uas muaj lub siab ua haujlwm channel, lossis ultra-zoo, hloov pauv hloov catheter ncaj qha los ntawm qhov chaw nres nkoj no. Nrog kev pabcuam ruaj khov ntawm cov cuab yeej pabcuam ntawm ob sab, coj los ntawm kev nthuav dav tiag tiag - lub sijhawm cov duab ntawm lub vijtsam, lub hau catheter tau raug muab tso rau hauv ob peb centimeters rau hauv tubal lumen ntawm fimbria ntawm lub raj mis los yog ib qho me me incision ua rau ntawm lub ampulla.

Tom qab ntawd, siab -zoo embryo ncua kev kawm ntawv npaj nyob rau hauv lub laboratory yog infused rau hauv lub ampulla nyob rau hauv ultra- meej ntim tswj - qhov chaw ntawm fertilization.

Kauj Ruam 4: Kev tshem tawm cov cuab yeej thiab qhov txhab kawThaum ua tiav cov txheej txheem, tag nrho cov cuab yeej raug rho tawm los ntawm lawv cov trocars. Lub pneumoperitoneum yog deflated nyob rau hauv lub zeem muag laparoscopic, thiab tag nrho cov trocars raug tshem tawm. Cov incisions me me raug kaw nrog intradermal sutures los yog cov ntaub so ntswg nplaum, tawm hauv qhov pom tsis tshua pom.

Thoob plaws hauv tag nrho cov txheej txheem, lub trocar system tsim ib qho chaw ruaj khov, meej ua haujlwm uas tso cai rau kev sib koom tes ntawm ntau yam twj paj nruag. Zoo li zoo-tsim chaw nres nkoj, cov trocars ua rau "lub nkoj ntawm lub neej" - embryos - xa mus rau qhov chaw nyab xeeb thiab raug rau hauv "sov dej" - lub raj dej, nyob rau hauv ib qho ze tshaj plaws rau lub tswv yim ntuj.

Lub zog ntawm Cov Khoom Siv Kev Tshawb Fawb: Kev Ua Haujlwm Sib Piv ntawm Laparoscopic Trocars rau Kev Kho Menyuam Yaus Me Me

Laparoscopic tubal oocyte hloov chaw thiab cov kev phais zoo sib xws ua rau muaj kev nruj heev rau cov neeg mob tsis muaj menyuam, cov ntaub so ntswg sib xws thiab kev ua haujlwm tactility. Cov khoom xaiv ntawm cov cuab yeej phais nws tus kheej embodies cov kev xav txawv. Raws li thawj qhov kev phais mob, laparoscopic trocars tau hloov zuj zus los ntawm cov khoom siv hlau ib txwm siv rau cov polymers niaj hnub, ua rau muaj kev sib tw hauv kev ua haujlwm, kev nyab xeeb thiab nqi.

Stainless hlau sawv raws li lub sijhawm -lub hauv paus rau laparoscopic trocars. Nws lub zog ua haujlwm zoo tshaj plaws thiab hnav tsis kam ua kom lub cannula tseem tsis tau zoo thiab tsis muaj cov khib nyiab hlau thaum rov punctures thiab nquag ntsuas. Ultra- siab polishing precision enables smooth insertion thiab extraction ntawm cov twj paj nruag thiab minimizes ua hauj lwm kev co - ib tug tseem ceeb kom zoo dua rau tubal oocyte hloov, uas yuav tsum tau millimeter -scale manipulation nyob rau hauv lub zeem muag.

Tsis tas li ntawd, stainless hlau tuaj yeem rov ua dua siab dua - qhov kub thiab siab - siab kom tsis muaj menyuam, sib piv cov txheej txheem rov ua cov txheej txheem hauv cov chaw ua haujlwm tsis muaj menyuam thiab ua rau nws zoo tagnrho rau cov khoom siv rov qab siv tau. Nws cov teeb meem tseem ceeb suav nrog qhov hnyav hnyav, thiab muaj peev xwm cuam tshuam nrog cov khoom siv hluav taws xob xws li ultrasonic scalpels, uas hu rau kev tiv thaiv kev tiv thaiv nruj.

Titanium alloys sawv cev rau qib hwm ntawm cov khoom siv kho mob hlau. Muab cov khoom sib npaug sib npaug rau cov hlau tsis muaj steel thaum ua kom sib zog, titanium alloys pab txo tus kws kho mob qaug zog thaum ua haujlwm ntev. Nws lub zog tseem ceeb tshaj plaws yog tshwj xeeb biocompatibility thiab corrosion kuj, nrog zero tsis zoo tshwm sim rau tib neeg cov ntaub so ntswg. Nws yog qhov tshwj xeeb tshaj yog rau cov txheej txheem cuam tshuam nrog lub cev txawv teb chaws ib ntus. Nyob rau hauv laparoscopic tubal oocyte hloov mus, titanium alloy trocars ntxiv txo qhov kev pheej hmoo ntawm cov ntaub so ntswg inflammatory teb, tsim kom muaj ib puag ncig zoo rau embryo implantation.

Qhov tshwm sim ntawm cov khoom siv pov tseg uas siv tau los ntawm kev kho mob - qib polymers xws li polycarbonate thiab polyether ether ketone (PEEK) yog ib qhokev nyab xeeb kiv puag ncig. Lawv qhov txiaj ntsig tseem ceeb yog nyob rau hauv kev tshem tawm tag nrho ntawm - kev pheej hmoo kis kab mob. Hom- cov khoom siv tsis muaj menyuam tshiab yog siv rau txhua qhov kev phais, tiv thaiv kev sib kis ntawm cov kab mob xws li prions thiab kab mob siab B los ntawm cov cuab yeej kho mob.

Polymers muaj cov xov tooj cua zoo heev thiab tsis cuam tshuam nrog kev ua haujlwm fluoroscopy. Lub caij no, cov tuam txhab lag luam tuaj yeem koom ua ke sophisticated los tiv thaiv- cov dej ntws tawm thiab nqus dej- cov kav dej rau hauv cov trocars pov tseg kom ua tiav qib siab - kev sib koom ua ke. Txawm li cas los xij, cov khoom lag luam no tseem coj cov teeb meem suav nrog cov pov tseg kho mob, cov nqi sib tw ntau dua rau kev siv sijhawm ntev -, thiab pom tias muaj kev ua haujlwm tsis zoo dua piv nrog cov khoom siv hlau ntawm qee tus kws phais.

Txhawm rau ua tiav, kev xaiv cov khoom siv rau trocars hauv laparoscopic tubal oocyte hloov pauv yuav tsum muaj kev ntsuam xyuas dav. Stainless hlau yog qhov nyiam los ntawm cov neeg ua ntej qhov kev ua haujlwm zoo tshaj plaws thiab kev ua haujlwm ntev -cov nqi siv nyiaj. Titanium alloy yog qhov kev xaiv rau cov kws kho mob uas hais txog biocompatibility thiab lub teeb yuag tsim. Cov tsev kho mob uas muab cov neeg mob muaj kev nyab xeeb tshaj txhua yam nrog cov peev nyiaj txaus yuav ua kom tag nrho cov khoom siv pov tseg polymer trocar. Tom qab tag nrho cov kev xaiv cov ntaub ntawv yog ib lub hom phiaj sib koom: tsim kom muaj kev nkag tau rau lub neej tshiab hauv txoj kev tsis tshua muaj kev cuam tshuam thiab kev nyab xeeb tshaj plaws.
