Raws li cov cuab yeej cuam tshuam ncaj qha nkag mus thiab sib cuag tib neeg lub mis mos cov ntaub so ntswg, cov qog subcutaneous, thiab cov kua dej hauv lub cev, biocompatibility, corrosion resistance, mechanical zog, thiab sterility assurance ntawm raw cov ntaub ntawv uas siv nyob rau hauv lub mis biopsy koob yog ib qho tseem ceeb ntawm kev txiav txim cov txheej txheem kev nyab xeeb, postoperative mob zoo zoo, thiab ntev- Tsis yog -kev kho mob- qib lossis cov khoom siv tsis tau zoo tuaj yeem ua rau cov ntaub so ntswg tsis lees paub, kev tsis haum tshuaj, cov hlau ion leaching, lossis txawm tias muaj xwm txheej kho mob hnyav vim yog cov khoom siv qaug zog. Yog li ntawd, cov kws tshaj lij kev lag luam ntawm cov koob txhaj tshuaj ntawm lub mis kho cov khoom siv kev nyab xeeb raws li cov kab liab kiag li, nruj me ntsis kom tsis txhob muaj nqi tsawg - cov ntaub ntawv nyoos xws li cov khoom siv rov ua dua tshiab thiab tsis yog - cov khoom siv tsis zoo. Lawv tau tsim ib qho kev tshawb fawb thiab nruj peb -tier xaiv cov ntaub ntawv thiab kev siv cov txheej txheem raws li cov hlau tsis muaj steel, titanium alloy, thiab kev kho mob-qib polymer composites, txhawb nqa los ntawm cov nqi sib tw- ntawm-cov ntaub ntawv (BOM) cov ntaub ntawv thiab cov ntaub ntawv pov thawj thib peb-cov ntaub ntawv pov thawj. Qhov no tso cai rau tag nrho - saw kaw- lub voj traceability tswj los ntawm cov khoom siv raw khoom kom tiav cov khoom tso tawm, tshem tawm ntau yam kev nyab xeeb kev nyab xeeb- xws li rhiab heev, corrosion, particle shedding, thiab teeb meem tshuaj leaching{17}} hauv paus hauv cov khoom tsis xws luag ntawm qhov chaw.

Qib 1: Kev kho mob-qib Reinforced Stainless Steel Substrate

Ib tug txhim khu kev qha thiab check reusable tov. Cov khoom siv no yog tsim tshwj xeeb rau cov koob tshuaj biopsy uas yuav tsum tau ua kom nquag plias, tsim kho thiab ua kom tsis muaj menyuam hauv tsev kho mob Central Sterile Supply Departments (CSSD). Cov neeg tsim khoom nruj me ntsis xaiv kev kho mob- qib zaub mov- cov ntaub ntawv tsis zoo stainless hlau xws li 304 thiab 316L, ua raws li cov qauv suav nrog GB/T 4234.1. Cov ntaub ntawv nyoos no tau ua kom huv huv los ntawm cov txheej txheem xws li lub tshuab nqus tsev thiab cov electroslag remelting, tshem tawm cov impurities xws li sulfur thiab phosphorus. Special heat treatment further refines the grain structure, resulting in a dense, uniform microstructure free of pores, inclusions, or microscopic cracks. Cov hlau tsis muaj cov khoom siv biocompatibility zoo heev, nrog hnyav hlau ion leaching (xws li npib tsib xee thiab chromium) tswj nruj me ntsis nyob rau hauv kev nyab xeeb txwv, txo qhov kev pheej hmoo ntawm liab, tsis haum tshuaj, los yog sterile o thaum sib cuag nrog cov ntaub so ntswg ntawm lub mis thiab lub cev kua. Tsis tas li ntawd, nws ua rau pom kev tiv thaiv corrosion zoo heev, muaj peev xwm ua rau lub sijhawm ntev rau hauv cov tshuaj tua kab mob xws li povidone-iodine, cawv, thiab ntsev. Txawm hais tias tom qab rov ua dua ntawm qhov siab -kub chav ua kom tsis muaj menyuam thiab qis -kub plasma sterilization, cov khoom tswj xyuas cov khoom siv zoo tshaj - khaws nws cov qauv qub, tiv thaiv xeb, thiab khaws cia puncture rigidity. Qhov no ua kom lub sijhawm ntev -lub sij hawm, ruaj khov reusability, txo cov tuam tsev ua haujlwm ntev - lub sij hawm siv tau thiab cov nqi tu.

Qib 2: Lub teeb yuag Titanium Alloy Premium Base Khoom

Qhov kev xaiv zoo tshaj plaws rau cov txheej txheem yooj yim thiab meej minimally invasive. Titanium alloy feem ntau yog siv nyob rau hauv siab -kawg biopsy koob qhov twg zoo dua tactile tawm tswv yim, tus neeg mob kev nplij siab, thiab meej piv txwv ntawm qhov tob tob los yog complex lesions yog qhov tseem ceeb. Compared to stainless steel, titanium alloy offers lower density and superior specific strength (strength-to-weight ratio), resulting in a lighter needle that feels more agile and comfortable in the physician's hand. Qhov no ua rau muaj kev tswj xyuas ntau dua thiab zoo ib yam ntawm qhov tob thiab lub kaum ntse ntse, txo qhov kev pheej hmoo ntawm kev raug mob mus rau ib puag ncig cov qog nqaij hlav noj qab haus huv lossis cov hlab ntsha vim kev siv tsis sib xws. Tsis tas li ntawd, titanium alloy muaj qhov zoo dua toughness thiab qaug zog tiv thaiv, zoo tiv thaiv kev ntxhov siab thaum nkag mus rau hauv cov ntaub so ntswg los yog sib sib zog nqus ntawm lub mis, txo qhov muaj peev xwm ntawm rab koob deformation lossis tawg thaum phais. Nrog rau biocompatibility zoo heev thiab corrosion kuj-feem ntau tshaj cov hlau stainless-titanium alloy yog tshwj xeeb tshaj yog haum rau cov poj niam uas muaj tawv nqaij rhiab heev los yog tshwj xeeb physiological mob, nrog rau cov hwm private tsev kho mob leej niam thiab cov chaw zov me nyuam tshwj xeeb uas xav tau cov qauv siab tshaj plaws hauv kev kho mob zoo.

Theem 3: Cov Khoom Siv Kho Mob Pov Tseg Polymer Substrate

Tus qauv ntsuas rau kev tswj kab mob. Tsim tshwj xeeb rau ib leeg - siv cov koob tshuaj tsis muaj menyuam, ua raws li "ib tus neeg, ib qho siv, ib qho pov tseg" txoj cai. Cov neeg tsim khoom ua tib zoo xaiv cov khoom siv kho mob- qib virgin polymer cov ntaub ntawv (xws li cov qib tshwj xeeb ntawm kev kho mob polycarbonate thiab ABS), nruj me ntsis txwv tsis pub ntxiv cov khoom siv rov ua dua tshiab kom ntseeg tau cov khoom siv purity, tsis yog - tshuaj lom, tsis muaj ntxhiab, thiab zoo heev toughness thiab rigidity, txo qhov kev pheej hmoo ntawm kev tawg thaum lub sijhawm ua haujlwm. Ib qho - siv tus qauv tsim los tshem tawm txoj kev pheej hmoo ntawm kev hla - kis kab mob los ntawm kev siv cov cuab yeej rov qab los ntawm cov neeg mob, ua tau raws li cov qauv kev tswj hwm tus kab mob nruj zuj zus hauv cov tsev kho mob niaj hnub no. Rau txhua qib substrate, cov ntaub ntawv ywj pheej thiab cov lej batch traceability tau tsim nyob rau hauv tag nrho cov txheej txheem -los ntawm kev tshuaj xyuas thiab kev tsim khoom mus rau cov khoom tiav. Txhua pawg tuaj nrog cov ntaub ntawv sib xws, suav nrog cov ntaub ntawv txheeb xyuas tshuaj lom neeg, cov txiaj ntsig kev ntsuas kev ua haujlwm, thiab thib peb-cov ntaub ntawv pov thawj thib peb ntawm biocompatibility (xws li, cytotoxicity, rhiab heev, khaus), ua kom muaj kev sib haum xeeb nrog kev soj ntsuam xyuas los ntawm cov kws tswj xyuas tshuaj, kev tswj xyuas kab mob 1 thiab cov khoom pov thawj ntawm kev noj qab haus huv - ua kom muaj kev thaj yeeb nyab xeeb ntawm lub siab thiab ua raws tag nrho rau kev yuav khoom thiab kev siv thoob plaws cov chaw kho mob.
