Raws li lub ntiaj teb ua lag luam ntawm cov khoom siv phais mob me me, peb tau nthuav tawm cov kev daws teeb meem dav dav rau cov khoom siv ntawm laparoscopic trocars. Peb tau ua tiav cov khoom tiav matrix npog austenitic stainless hlau (304/316L), kev kho mob qib titanium alloy (TC4) thiab cov khoom siv kho mob tshwj xeeb. Los ntawm kev soj ntsuam lom neeg nruj heev thiab kev hloov kho cov txheej txheem, peb tau ua tiav tag nrho cov kev pab cuam los ntawm high-end reusable cov khoom mus rau cov nqi siv tau zoo dua. Qhov no txhais tau hais tias peb daim ntawv thov ntawm cov khoom siv tseem ceeb tau nce siab los ntawm tsuas yog ua tau raws li cov qauv kev tswj hwm mus rau qhov tseem ceeb ntawm cov ntsiab lus ntawm kev kho mob.

R&D keeb kwm yav dhau thiab cov ntsiab lus tseem ceeb mob

Raws li txawv teb chaws-lub cev channel indwelling nyob rau hauv cov neeg mob rau lub sij hawm ntev, laparoscopic trocars cia siab rau kev xaiv cov ntaub ntawv raws li lub hauv paus thiab tseem ceeb tshaj kev tiv thaiv kev nyab xeeb. Cov kev daws teeb meem ib leeg ib leeg raug kev txom nyem los ntawm cov kev txwv tseem ceeb: kev ua tsis tiav stainless hlau muaj kev pheej hmoo ntawm nickel ion leaching thiab hypersensitivity; titanium alloy nta cov nqi siab thiab kev ua haujlwm nyuaj; Thaum ntxov-tiam polymers tsis ua raws li qhov xav tau ntawm cov kev phais nyuaj raws li lub zog, nruj thiab nkag siab tsis kam.Qhov kev sib tw tseem ceeb nyob rau hauv yuav ua li cas los lav cov biosafety (non-cytotoxicity, non-sensitization, non-carcinogenicity) thaum ua tau raws li cov kev xav tau ntawm cov khoom siv xws li cov khoom siv zog, corrosion resistance, torsion resistance thiab clear intraoperative. Kev ua lag luam xav tau hierarchical, customizable cov ntaub ntawv kev tshawb fawb daws teeb meem tsim los ntawm qhov tob soj ntsuam kev pom.

Core Technological Innovations

Peb qhov kev tsim kho tshiab yog tsim kom muaj peb-dimensional mapping database thiab xaiv cov qauv txuas nrog cov xwm txheej kho mob, cov khoom siv thiab cov txheej txheem siv. Tsis yog ib qho yooj yim muab tso ua ke ntawm cov ntaub ntawv, nws yog lub culmination ntawm systematic engineering:

• Stainless hlau Trocars: Peb txais yuav ultra-low-carbon 316L austenitic stainless hlau. Los ntawm kev kho tus kheej lub tshuab nqus tsev kho kom zoo thiab cov txheej txheem electrolytic polishing, peb txhim kho qhov ntom ntom thiab sib xws ntawm qhov chaw passivation zaj duab xis, txwv kev hnyav-hlau ion leaching mus rau qib ib-billion (ppb), deb tshaj qhov yuav tsum tau ntawm ISO 10993 tus qauv.
• Titanium Alloy Trocars: Peb tau kov yeej cov kev tsis sib haum xeeb hauv kev sib sib zog nqus-qhov machining thiab txias-hardening tswj rau precision nyias-walled titanium alloy raj. Siv cov cuab yeej tshwj xeeb txiav thiab cov txheej txheem txias, peb ua tiav daim iav-qib sab hauv phab ntsa tiav. Muab tag nrho cov kev ua si rau nws qhov zoo ntawm lub zog tshwj xeeb, zoo heev biocompatibility (sib haum nrog tib neeg cov pob txha cov ntaub so ntswg) thiab tsis-magnetic cuam tshuam, titanium alloy trocars tshwj xeeb yog tsim los rau high-end, ntev-lub sij hawm los yog imaging-tshaj kev phais.
• Polymer Trocars: Kev koom tes nrog cov tuam txhab tshuaj lom neeg sab saum toj, peb tau tsim kev cai iav-fiber-reinforced kho mob-qib PEEK (polyetheretherketone) thiab tshwj xeeb polycarbonate composites. Los ntawm kev hloov kho molecular thiab ntxiv dag zog, cov polymers no muaj qhov pom tseeb ntawm X-ray, lub teeb yuag thiab kev tswj tus nqi, thaum xa cov hlau sib piv bending kuj thiab qhov ntev stability. Lawv muab cov kev ua tau zoo, raug nqi zoo rau kev lag luam khoom siv pov tseg.

Mechanisms ntawm Action

Cov txheej txheem tseem ceeb ntawm cov ntaub ntawv sib txawv yog nyob rau hauv lawv cov kev sib raug zoo nrog tib neeg lub cev ib puag ncig. 316L stainless hlau tso siab rau nws cov ntom ntom chromium-oxide passivation zaj duab xis los tsim ob lub cev thiab tshuaj tiv thaiv kev tiv thaiv lub cev dej yaig, ua kom muaj kev sib raug zoo nrog tib neeg cov ntaub so ntswg. Kev kho mob qib titanium alloy mus ntxiv: nws cov txheej txheej oxide nthuav qhia kev sib raug zoo nrog cov ntaub so ntswg lom neeg, zoo heev inhibiting non-specific protein adsorption thiab alleviating inflammatory reactions kom paub txog bio-friendliness. Cov polymers tshwj xeeb kho mob tshem tawm kev pheej hmoo ntawm cov hlau ions tag nrho ntawm cov qauv tsim qauv zoo. Lawv cov khoom qis-nto-zog txo cov ntaub so ntswg adhesion, thiab tunable elastic modulus muab kev yooj yim dua piv nrog cov hlau, txo qis siab ntawm qhov chaw ntawm qhov chaw. Peb cov thev naus laus zis ua kom muaj peev xwm ua tau zoo ntawm cov ntaub ntawv no.

Kev txheeb xyuas qhov ua tau zoo

Tag nrho peb cov ntaub ntawv tau dhau los ntawm ISO 10993 kev tshuaj ntsuam xyuas kev lom neeg, suav nrog cytotoxicity, rhiab heev, intracutaneous reactivity thiab mob toxicity. Hauv kev ua kom muaj kev laus sai thiab simulated lub cev ua kua hauv lub cev, cov hlau-ion leaching los ntawm peb cov khoom 316L tsuas yog 30% ntawm qhov nruab nrab ntawm kev lag luam. Titanium alloy trocars qhia tsis muaj pitting corrosion, discoloration los yog degradation nyob rau hauv txhua yam khoom tom qab mus txog 500 cycles ntawm high-pressure chav sterilization. Polymer trocars dhau 12-teev creep resistance test nyob rau hauv simulated intra-abdominal siab siab (20 mmHg) rau cov neeg mob rog, nrog rau deformation tus nqi qis dua 0.5%. Cov ntaub ntawv soj ntsuam kev soj ntsuam pom pom tias muaj qhov tshwm sim tsawg dua ntawm kev hnov ​​​​qab txawv teb chaws lub cev thiab mob ntev ntawm qhov chaw phais rau kev phais siv peb cov titanium alloy thiab qib high-qib stainless hlau trocars.

R&D Strategy thiab Philosophy

Peb ntseeg ruaj khov:Tsis muaj cov khoom siv zoo tshaj plaws, tsuas yog cov khoom tsim nyog tshaj plaws rau kev kho mob scenarios.Peb lub tswv yim R & D tso tseg kev siv tshuab tsis zoo hauv kev xaiv cov khoom siv. Txais yuav qhov kawg-oriented mus kom ze, peb muab cov khoom thiab cov txheej txheem kev daws teeb meem los ntawm cov kev xav tau ntawm kev kho mob tiag tiag, xws li hom kev phais, lub sijhawm, tus neeg mob lub cev thiab cov nqi txiav txim siab. Raws li cov kws tsim khoom siv hauv cov khoom siv kho mob, peb nkag siab tob txog cov yam ntxwv thiab lub peev xwm ntawm txhua yam khoom siv. Los ntawm cov txheej txheem ua kom zoo dua qub, peb ua kom cov ntaub ntawv ua haujlwm ruaj khov, nyab xeeb thiab ntseeg tau thaum lub sijhawm phais, muab cov kws phais nrog ntau txoj kev xaiv.

Yav tom ntej Outlook

Tsiv mus tom ntej, peb yuav tshawb nrhiav cov khoom siv biofunctional rau yav tom ntej. Piv txwv li, peb yuav tshawb fawb cov txheej txheej ntse rau trocars, suav nrog cov tshuaj tua kab mob thiab cov tshuaj tiv thaiv kab mob, cov tshuaj tiv thaiv kev tiv thaiv-tso tawm txheej rau cov tshuaj tiv thaiv adhesion, lossis cov khoom siv hluav taws xob hloov pauv nrog kev ntsuas kub / siab. Lub caij no, peb tab tom ntsuas qhov ua tau ntawm bioabsorbable cov ntaub ntawv sib xyaw rau cov kev phais tshwj xeeb luv luv. Peb lub hom phiaj yog ua kom dhau los ntawm biocompatibility mus rau biofunctionalization, hloov trocars los ntawm kev nkag mus rau hauv cov khoom siv kho mob ntse uas nquag txhim kho cov kev phais microenvironment hauv zos thiab txhawb kev kho qhov txhab.
