Rubber sheath ntawm endoscope yog ib qho tseem ceeb ntawm cov khoom siv endoscopic. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv cov khoom siv kho qhov muag thiab cov khoom siv hluav taws xob hauv qhov endoscope, thaum ua kom cov khoom siv tau yooj yim thiab ruaj khov thaum siv. Yog xav paub ntxiv txog cov khoom lag luam ntawm cov khoom tau hais los saum toj no, thov nyem rau hauv qab no.
Cov roj hmab no feem ntau yog ua los ntawm cov khoom siv elastomer siab, xws li thermoplastic elastomers (TPE), thermoplastic roj hmab (TPR), lossis thermoplastic vulcanizates (TPV). Cov ntaub ntawv no muaj cov elasticity zoo heev, kev puas tsuaj, tshuaj lom neeg corrosion, thiab biocompatibility zoo, ua rau lawv zoo tagnrho rau kev siv hauv kev kho mob.
Los ntawm txoj kev xav, tus tsim ntawm endoscope roj hmab sheath yuav tsum xav txog cov complex txav ntawm lub endoscope thaum siv, xws li khoov thiab twisting. Yog li ntawd, cov khoom yuav tsum muaj txaus elasticity thiab yooj los xyuas kom meej tias lub endoscope yuav smoothly nkag mus rau tib neeg lub cev rau kev soj ntsuam los yog kev kho mob. Nyob rau tib lub sijhawm, cov ntaub qhwv kuj yuav tsum muaj cov khoom sib khi zoo los tiv thaiv lub cev los yog lwm yam khoom los ntawm kev nkag mus rau hauv qhov endoscope thiab ua rau muaj kev puas tsuaj lossis kev sib kis.
