Covlaparoscopic cannula(tseem hu ua Trocar lub tes tsho lossis trocar cannula) yog cov cuab yeej siv tseem ceeb hauv kev phais laparoscopic minimally invasive laparoscopic los tsim cov kab mob plab plab, qhia txog endoscopes thiab cov cuab yeej phais mob (grasping forceps, electrosurgical txiab, ultrasonic scalpels, thiab lwm yam), thiab tswj kev ua haujlwm. Tus qauv cannula muaj obturator (nrog rau lub ntsej muag ntse lossis lub ntsej muag), lub cev cannula, lub kaw lus kaw lus (nrog rau lub kaw lus thiab ntsuas ntsuas), thiab cov cuab yeej kho (xov lossis zais pa). Nws lub hauv paus ntsiab lus ua haujlwm yog: tom qab pneumoperitoneum raug tsim, tus kws phais tau ntxig obturator ua ke nrog cov cannula rau hauv lub plab kab noj hniav; Thaum lub obturator raug tshem tawm, lub cannula tseem nyob rau hauv lub plab phab ntsa raws li ib tug channel rau cov twj paj nruag nkag thiab tawm. Ua tau -nyob rau hauv silicone los yog polyurethane sealing li qub tuav airtightness thaum cov twj paj nruag raug muab tso thiab cia li kaw thaum tshem tawm kom tsis txhob poob ntawm pneumoperitoneum.
Los ntawm kev saib xyuas tus nqi saib xyuas, laparoscopic cannula ncaj qha txiav txim siab txog kev nyab xeeb ntawm qhov chaw nkag hauv kev phais me me. Piv nrog rau cov tsoos qhib incisions ntsuas 10-15 cm, tus qauv cannulas tsuas yog 3-12 hli apertures, txo qhov mob tom qab phais, txo qhov tshwm sim ntawm incisional hernias, shortening tsev kho mob nyob ntawm 2-4 hnub, thiab ua tau raws li cov kev xav tau ntawm cov tshuaj pleev ib ce. Cov khoom lag luam tseem ceeb raug cais los ntawm cov qauv tsim rau hauv: bladed trocars (txiav cov ntaub so ntswg rau kev nkag), bladeless / dilating trocars (blunt sib cais ntawm fascial txheej rau nkag, txo vascular raug mob), kho qhov muag trocars (tsim-} nyob rau hauv laparoscope channel tso cai rau ncaj qha pom ntawm cov txheej txheem puncture, txo cov kev pheej hmoo loj ntawm cov neeg mob thiab raug mob. Kev phais mob plab ua ntej), thiab Hasson- hom trocars (qhib qhov chaw, siv rau kev rov ua haujlwm lossis rooj plaub uas xav tias muaj adhesions).
In terms of specifications, cannula diameter (Trocar Size) is a key metric for procurement classification: 3mm/5mm sizes are mostly used for auxiliary ports (e.g., channels for dissecting forceps and grasping forceps), accounting for approximately 40%–45% of total sales volume; 10mm serves as the main operating port (accommodating 30° laparoscopes), accounting for about 30%–35%; 12mm is used for introducing linear cutting staplers or specimen extraction, accounting for about 15%–20%; 15mm and above are used for bariatric surgery or extraction of large specimens. Cannula lengths are typically 70–110 mm (adult standard), short-type 50 mm (pediatric/thin patients), and extended 120–150 mm (obese patients with BMI >35). Hais txog cov ntaub ntawv, cov khoom siv rov siv tau feem ntau yog siv kev kho mob - qib 316L stainless hlau lossis titanium alloy, muaj peev xwm tiv taus siab - kub thiab siab - siab ua kom tsis muaj menyuam (134℃, tshaj 200 cycles); Cov khoom siv pov tseg siv kev kho mob- qib polycarbonate (PC), ABS, lossis PEEK polymers, ua ntej-sterilized ntawm lub Hoobkas (EO lossis irradiation), tshem tawm txoj kev pheej hmoo ntawm kev sib kis - kis.
Kev lag luam laparoscopic cannula thoob ntiaj teb tau muaj nuj nqis kwv yees li ntawm 870millionto1.8 billion hauv 2025 (nrog rau tag nrho cov khoom lag luam trocar), nrog rau kwv yees li CAGR ntawm 5.5% -12.3% txij xyoo 2030 txog 2035. Nyob rau hauv qhov no, cov khoom siv polymer pov tseg tau loj hlob sai dua ib xyoos ib zaug, kev tswj hwm cov kab mob hauv ntiaj teb tau nce zuj zus. 6% -8% hauv cov txheej txheem laparoscopic ntim. Hauv Suav teb, tus naj npawb ntawm kev phais laparoscopic tau tshaj 8 lab hauv 2025, thiab "Txheej Lub Tuam Txhab Project" tau txhawb nqa lub peev xwm laparoscopic hauv lub nroog- cov tsev kho mob theem, tsav tsheb txhua xyoo kev thov tshiab rau cannulas rau ntau tshaj 100,000 teeb, nrog rau cov khoom siv hauv tsev nkag mus txog 60%. Thaum cov khoom no zoo li yooj yim, nws yog qhov yuav tsum tau ua, siab tshaj - ntim khoom siv tau thiab muaj kev nyab xeeb tseem ceeb hauv txhua txoj kev laparoscopic. Nws txoj kev ruaj ntseg sealing, los tiv thaiv- qauv tsim, thiab kev ruaj ntseg puncture yog peb qhov kev cuam tshuam loj hauv kev sib tw ua lag luam.
