Lub raum Cannula

Pain Point

Hauv urology, cov txheej txheem xws li percutaneous nephrolithotomy (PCNL), ureterorenoscopy, thiab nephrostomy yuav tsum tau nkag mus rau lub raum khaws cov kab ke- ib puag ncig uas muaj cov pob zeb tawg, ntshav, zis, siab- nrawm irrigation, thiab tawg, hemorrhage{2. Lub raum cannulas uas twb muaj lawm ntsib cov kev txwv loj heev: cov raj polymer feem ntau kink nyob rau hauv dej siab, tsis pom kev thiab impeding ntsuas txav; rigid stainless hlau tubes muaj feem yuav mucosal laceration los yog perforation thaum navigating mob raum cov ces kaum; braided hlab tsim cov duab kos duab hauv qab fluoroscopy, cuam tshuam nrog pob zeb hauv zos. Urologists xav tau ib tug cannula uas tswj siab - dej ntws, lem los ntawm sharply angulated calyces, resists corrosion los ntawm cov zis chemistry, thiab tseem radiolucent txaus kom pom cov pob zeb tsis muaj kev cuam tshuam.

Txoj Cai

Cov qauv tsim ntawm lub raum cannula yoglub fusion ntawm cov dej dynamics thiab structural mechanics. Siv 316L stainless hlau rau nws superior tiv thaiv chloride thiab uric acid corrosion, laser txiav tsimsab -slotslos yogcuam ​​tshuam spiralsntawm lub cev phab ntsa. Sab-slots tso cai rau cov kua dej nkag los ntawm ntau qhov kev qhia, ua rau muaj kev kub ntxhov uas ntws cov pob zeb khib nyiab thaum tiv thaiv kev ua tiav cov mucosal adhesion ntawm lub ntsis. Kev cuam tshuam kauv txiav impart kev ua raws cai rau navigating nqaim infundibula thiab calyceal caj dab. Txiav ceev precisely tswj bending txhav thiab torque kis tau tus mob. Lub 0.012 hli kerf yields exceptionally smooth qhov npoo, txo cov ntaub so ntswg snagging. Tsis tas li ntawd, kev sib koom ua ke ntawm radiopaque micro-bridges ncaj qha rau hauv cov qauv txiav tshem tawm qhov xav tau ntawm cov cim cim cais, khaws cia qhov qis - profile sab nraud thiab zam pob zeb- pom kev cuam tshuam hauv fluoroscopy.

Kev faib khoom siv

• Ureterorenoscope Cannula: ~ 3.5 hli txoj kab uas hla, 316L nrog distal sab -slots rau saj zawg zog ureteroscopy nkag thiab irrigation.
• PCNL Access Cannula: Loj-dhau (F24–F30), txhav qhov sib thooj kom tiv thaiv fascial tsis kam, hloov pauv qhov chaw seem rau lub raum lub raum hloov pauv.
• Nephrostomy Drain Cannula: 316L sab-slot design for post-operative long-term drainage, xav tau biocompatibility zoo heev thiab anti-encrustation zog.
• Saj zawg zog Renal Navigation Cannula: Nitinol distal ntu rau nkag mus rau qhov nyuaj qis dua -ncej calyces thiab calyceal diverticula.
• Bespoke Stone-Retrieval Cannula: Integrate pob tawb ports thiab aspiration side-slots rau ib txhij "suav thiab suction" pob zeb tshem tawm.

Phau Ntawv Qhia

1. Flow Over ID: Tsis txhob nrhiav qhov siab tshaj plaws sab hauv ib leeg. xamthaj chaw irrigation zoo. Nce sab-slot suav thiab optimizing cov duab tuaj yeem ua tau ntau dua qhov tseeb ntws ntawm tib txoj kab uas hla sab nraud thaum txo cov phab ntsa tuab.
2. Kev Tiv Thaiv Distal: Txhua sab - cov npoo yuav tsum tau radiused los tiv thaiv mucosal laceration. Lub ntsiab lus ntawm qhov distal yuav tsum siv cov kev txiav radial los faib cov bending zog sib npaug, tsis txhob muaj kev cuam tshuam nyuaj.
3. Integrated Radiopacity: Tsim 2–3 radiopaque micro-bridges nyob rau hauv 5 mm ntawm lub distal kawg. Cov choj no tau pom meej meej hauv X-ray tab sis tsis protrude zoo li cov kab kos ib txwm muaj.
4. Simulated Pob Zeb Xeem: Siv cov porcine ob lub raum los yog hluavtaws phantoms infused nrog simulated pob zeb tawg thiab cov ntshav los ntsuam xyuas cov tawg tawg efficiency nyob rau hauv aspiration thiab irrigation hom.
5. Nto Passivation: Tag nrho cov 316L cannulas yuav tsum tau ua nruj me ntsis passivation thiab electropolishing los ua ib tug chromium - nplua oxide txheej, tiv thaiv chloride thiab uric acid corrosion thoob plaws hauv lub neej ntawm cov cuab yeej.

Tiag -Kev Paub Txog Ntiaj Teb

Hauv kev sib piv PCNL txoj kev tshawb fawb, cov kws phais siv cov pa PVC sheaths feem ntau xav tau ntau qhov kev tshem tawm kom tshem cov pob zeb khib nyiab, thiab cov dej tsis zoo rov qab los ua rau tsis pom kev tsis pom kev. Hloov mus rau lub laser-txiav 316L sab-slot cannula txo qhov kev sib pauv hloov pauv, txo lub sijhawm ua haujlwm luv luv los ntawm 25%, thiab txo qis kev pheej hmoo los ntshav vim yog sab- cov slots tiv thaiv kev ua tiav cov lus nplaum rau mucosa. Qhov kev paub no qhia tau tiasoptimizing kua txoj kev outperforms tsuas yog loj lumen txoj kab uas hlahauv kev txhim kho kev phais kom zoo.

Xaus

Lub raum cannula ua haujlwm nyob rau hauv ib qho ntawm cov tshuaj cuam tshuam qhov chaw hnyav tshaj plaws - tawm tsam nrog pob zeb, ntshav, tso zis, thiab siab - dej siab ib txhij. Nws txoj kev vam meej yog nyob ntawm tsis yog tsuas yog ntawm corrosion- cov ntaub ntawv tiv taus thiab hloov pauv tau yooj yim tab sis kuj tseem nkag siab tob txog cov dej dynamics. Laser txiav elevates lub raum cannula los ntawm ib tug passive raj mus rau ib tug active surgical pab, ncaj qha txhim kho pob zeb - tus nqi pub dawb thiab cov txheej txheem kev nyab xeeb.

Outlook & Cov Lus Pom Zoo

Yav tom ntej lub raum cannulas yuav suav nroganti- pob zeb txheej(piv txwv li, hydrophilic / hydrophobic alternating txheej) kom txo tau fragment adhesion thiab tej zaum yuav integrateUltrasonic lithotripsy sojntsuam channel. Urology OEMs yuav tsum ntsuasfragment kev thauj tus nqithiabirrigation efficiency nyob rau hauv loades tsis yog cia siab rau Fabkis qhov loj me xwb. Kev sib raug zoo ntawm cov tuam ntxhab thiab cov kws kho mob urologist yog qhov tseem ceeb los tsim cov txheej txheem - tshwj xeeb cannulas rau cov pob zeb nyuaj morphologies.
