I-12V DC stepper motor ehlanganisa i-8mm micro motor, i-encoder enezigaba ezi-4 kanye ne-gearbox yokunciphisa isilinganiso esingu-546:1isetshenziswe ngokusemthethweni kusistimu ye-stapler actuator. Lobu buchwepheshe, ngokudluliswa kwe-ultra-high-nemba kanye nokulawula okuhlakaniphile, kukhulisa kakhulu ukuzinza nokuphepha kwe-anastomosis yokuhlinzwa, kusetha ibhentshimakhi yemboni entsha yemisebenzi yokuhlinza ehlasela kancane.
Le motor ishaya ibhalansi ephelele phakathi kwe-miniaturization ne-torque ephezulu. Iyinjini engu-8mm ultra-miniature motor: enomklamo we-rotor ongena core, yehlisa ivolumu ngo-30% uma iqhathaniswa nesizukulwane sangaphambili ngenkathi iqinisekisa idrayivu ye-voltage ephansi engu-12V, iyenze ifaneleke kakhulu indawo yokusebenza encane yama-endoscopic staplers. Isishumeki esinembayo esiphezulu sezinga elingu-4: Ngokulungiswa okungu-0.09°, singanikeza impendulo yesikhathi sangempela ngesivinini semoto nendawo, iqinisekise ukuthi iphutha lebanga ngalinye lokuthunga phakathi nenqubo yokuthunga lilawulwa ngaphakathi kuka-±0.1mm, kugwenywe ubungozi bokungahambi kahle kwezicubu noma ukopha. 546:1 Ibhokisi legiya lezigaba eziningi: Ngesakhiwo sokunciphisa amagiya eplanethi esinezigaba ezi-4, i-torque ye-stepper motor iyakhuphuka ibe ngu-5.2N·m (umthwalo olinganiselwe). Khonamanjalo, amagiya enziwe ngensimbi engagqwali yezinga lezokwelapha, enciphisa izinga lokuguga ngo-60% nokuqinisekisa ukuphila kwemijikelezo engaphezu kuka-500,000.
Ngemva kokuhlolwa komtholampilo, uguquko olusuka ku-"mechanical suture" ukuya ku-"intelligent anastomosis" lufinyelelwe. Ekuhlolweni kwezilwane, i-stapler ehlakaniphile efakwe le moto yabonisa izinzuzo ezibalulekile: Isivinini sokuphendula esithuthukisiwe: Ngenxa yokulawulwa kwe-loop evaliwe yesishumeki, isikhathi sokuqalisa imoto safinyezwa saba ngu-10ms, futhi amandla e-suture angalungiswa ngokushesha phakathi nokusebenza. Idizayini yokuncishiswa kwesilinganiso esingu-546 yenza injini ikwazi ukugcina ukuphuma kahle ngesivinini esiphansi, inciphisa ukusetshenziswa kwamandla okusebenza okukodwa ngo-22%. Isekela iphrothokholi yokuxhumana yebhasi ye-CAN futhi ingahlanganiswa ngaphandle komthungo nesistimu yokulawula yerobhothi elihlinzayo ukuze kuzuzwe ukusebenza okukude nokunembayo.
Lesi sixazululo sedrayivu esididiyelwe kakhulu asisebenzi kuma-staplers kuphela, kodwa singanwetshwa kumishini yezokwelapha enemvamisa ephezulu efana nama-endoscope namaphampu omjovo esikhathini esizayo. Ngokuzayo, izinjini ezihlakaniphile ezinezilinganiso eziphezulu zokunciphisa nomsindo ophansi zizogxila emncintiswaneni.
