Pain PointsCov khoom tsis xws luag thiab tsis ruaj tsis khov kev ua kom tsis muaj menyuam yog qhov tseem ceeb zais kev phom sij cuam tshuam rau kev nyab xeeb ntawm laparoscopic nkag tshuab. Qee cov khoom siv tsis yog-tus qauv puncture siv cov khoom siv qis- qib alloy nrog cov tsis zoo corrosion kuj, uas ua rau xeb, burrs thiab degradation nto tom qab rov ua dua siab dua - kub kom tsis muaj menyuam. Rough koob nto ua rau cov ntaub so ntswg sib txhuam thaum lub plab phab ntsa nkag mus rau hauv lub plab, ua rau muaj kev raug mob ntau dua, los ntshav thiab mob tom qab phais. Tsis yog- kho mob- cov ntaub ntawv qib siab kuj tseem tuaj yeem ua rau cov ntaub so ntswg khaus hauv zos, cov tshuaj tiv thaiv kab mob thiab kev kho qhov txhab qeeb. Tsis tas li ntawd, kev ua haujlwm tsis zoo tuaj yeem ua rau rab koob khoov lossis txawm tias pob txha tawg thaum lub plab phab ntsa tuab, tsim kom muaj kev phais mob hnyav thiab muaj kev pheej hmoo ntawm lub cev txawv teb chaws. Cov khoom siv no-cov teeb meem cuam tshuam tsis yog tsuas yog txo cov cuab yeej siv zog xwb tab sis kuj cuam tshuam ncaj qha rau cov neeg mob kev nyab xeeb thiab kev ua haujlwm ntawm kev phais.
Txoj Cai Ua HaujlwmKev ua tau zoo heev ntawmVeress koobyog tsim los ntawm kev kho mob stainless hlau khoom siv tshuab. Kev kho mob stainless hlau yog dav siv hauv cov cuab yeej phais vim nws siab biocompatibility, corrosion kuj thiab txhua yam muaj zog. Nws tuaj yeem tiv taus qhov siab dua - siab ua kom tsis muaj menyuam yam tsis muaj kev hloov pauv loj hauv qhov chaw zoo, hardness lossis kev ntseeg ruaj khov. Cov khoom siv polished nto yuav txo tau kev sib txhuam coefficient, ua kom tsawg - tiv thaiv txheej nkag los ntawm daim tawv nqaij, fascia thiab peritoneum. Nws lub siab rigidity kom ntseeg tau tias lub cev rab koob lub cev tseem ncaj thiab ruaj khov txawm tias nkag mus rau hauv cov ntaub so ntswg ntawm lub plab. Nyob rau tib lub sijhawm, stainless hlau cov tshuaj lom neeg ruaj khov txo qhov kev pheej hmoo ntawm cov ntaub so ntswg tshem tawm, o thiab hla - kab mob, ua rau nws tsim nyog rau cov cuab yeej siv kho mob rov siv tau thiab ua kom tsis muaj menyuam.
Kev faib khoom sivRaws li cov ntaub ntawv qib thiab cov txheej txheem txheej txheem, Veress koob tuaj yeem muab faib ua peb pawg. Ua ntej, tus qauv kev kho mob stainless hlau qauv, uas yog cov khoom siv dav tshaj plaws hauv kev kho mob, muab kev sib npaug rigidity, corrosion kuj thiab nqi ua haujlwm. Thib ob, siab -precision polished stainless hlau qauv, uas dhau mus ntxiv electrolytic polishing kom ua tiav ib qho ultra- du sab hauv thiab sab nrauv, txo cov ntaub so ntswg puas thiab txhim kho kev xa khoom roj. Thib peb, ntxiv dag zog rau corrosion- cov qauv tiv thaiv, tsim rau cov tsev kho mob uas muaj siab - zaus ua kom tsis muaj menyuam thiab siv sijhawm ntev- rov siv dua, muaj kev txhim kho los tiv thaiv - oxidation thiab tiv thaiv - hnav cov khoom. Txhua pawg ua raws li qhov yooj yim qhov ntev ntawm 80-150 mm nyob rau hauv ntev, 2.5-5 mm nyob rau hauv lub cheeb txoj kab uas hla thiab 1.5-3 mm nyob rau hauv puab lumen, kom ntseeg tau kev kho mob compatibility nrog cov txheej txheem laparoscopic.
Phau Ntawv Qhia Txog Kev Ua HaujlwmUa ntej siv Veress koob, cov neeg ua haujlwm yuav tsum xub xyuas cov khoom zoo thiab kev ncaj ncees ntawm qhov ntsuas. Koob nrog pom xeb, burrs, dabtsi yog khoov los yog tip passivation yuav tsum muab pov tseg tam sim ntawd kom tsis txhob muaj kev pheej hmoo ntawm kev phais. Standard stainless hlau Veress koob yog haum rau feem ntau niaj hnub kev phais laparoscopic, thaum polished qauv raug pom zoo rau cov txheej txheem ilv, me nyuam cov neeg mob thiab cov neeg mob uas yuav tsum tau tsawg kawg nkaus cov ntaub so ntswg raug mob. Tom qab kev phais, cov cuab yeej yuav tsum tau muab ntxuav, tua kab mob thiab ua kom tsis muaj menyuam raws li cov txheej txheem hauv tsev kho mob. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev ntxuav lub lumen sab hauv, qhov chaw seem ntawm cov ntshav lossis cov ntaub so ntswg tuaj yeem cuam tshuam rau kev xa cov pa roj thiab ua rau muaj kev pheej hmoo kis mob. Kev ziab kom zoo thiab khaws cia yog qhov tsim nyog los tswj kom ntev - cov khoom ruaj khov.
Xyaum xyaumCov ntaub ntawv kho mob qhia tau hais tias siab - zoo stainless hlau Veress koob muaj kev ruaj ntseg txawm tias tom qab ntau lub voj voog ua kom tsis muaj menyuam, tsis muaj qhov nce ntawm qhov roughness lossis teeb meem. Piv nrog rau qis-cov cuab yeej siv hlau sib tsoo, cov koob kho mob stainless hlau txo qis cov ntaub so ntswg puas tsuaj ntau dua 50% thiab txo qhov tshwm sim ntawm qhov mob hauv zos. Polished Veress koob muaj txiaj ntsig tshwj xeeb rau cov neeg mob rog rog thiab rov ua kev phais plab, qhov uas txo qis kev sib txhuam tuaj yeem txhim kho qhov tseeb nkag thiab txo qhov mob tom qab. Tsis tas li ntawd, cov khoom siv tau zoo ua tau zoo pab cov tsev kho mob tsim kom muaj kev tswj xyuas cov cuab yeej txhim khu kev qha, txo cov khoom siv tsis tau npaj txhij thaum phais.
Summary thiab SublimationCov khoom siv thev naus laus zis yog qhov yooj yim lav rau kev nyab xeeb, kav ntev thiab kev kho mob ntawm Veress koob. Kev kho mob stainless hlau muab qhov tsim nyog ua ke ntawm biocompatibility, mechanical zog, corrosion resistance thiab sterilization stability, ua Veress koob txhim khu kev qha cov twj paj nruag rau laparoscopic phais. Qhov chaw du, siab rigidity thiab ruaj khov cov khoom ntawm cov cuab yeej stainless hlau ncaj qha txo qhov kev raug mob ntawm kev phais, kev pheej hmoo kis mob thiab kev ua haujlwm nyuaj. Yog li ntawd, cov khoom zoo yuav tsum tsis txhob suav hais tias yog ib qho tseem ceeb thib ob, tab sis yog ib qho tseem ceeb qhia txog kev nyab xeeb ntawm laparoscopic tag nrho.
Cov lus qhia yav tom ntejCov khoom siv optimization yav tom ntej ntawm Veress koob yuav tsom mus rau peb cov lus qhia. Ua ntej, tsim cov tshuaj tua kab mob stainless hlau txheej los txo cov kab mob microbial thiab kev pheej hmoo kis mob tom qab phais. Thib ob, txhim kho qhov sib npaug ntawm kev nruj thiab yooj yim los tsim cov koob nyias nyias uas muaj lub zog txaus thaum nkag mus. Thib peb, siv cov txheej txheem polishing saum npoo thiab nano- txheej txheej thev naus laus zis los txo cov ntaub so ntswg kev sib txhuam thiab lumen blockage. Cov kev txhim kho no yuav txhim kho kev nyab xeeb thiab kev pabcuam lub neej ntawm Veress koob, txhawb nqa cov qauv siab dua ntawm kev phais me me.
