Abstract

Ensemble plaque stérile (300), robot chirurgical (104) et système de robot chirurgical (10). L'ensemble plaque stérile (300) comprend une plaque de couverture de plaque stérile supérieure (320) et une plaque de couverture de plaque stérile inférieure (330) ; une zone de connecteur de dégagement (340) est formée par une zone enfermée par des premières parties de fixation (322) et des secondes parties de fixation (323) qui sont disposées sur la plaque de couverture de plaque stérile inférieure (330) ; une ouverture (311) est montée à demeure sur les premières parties de fixation (322) et les secondes parties de fixation (323) après avoir été ouverte au moyen d'une tension, de manière à former un canal de connecteur (350) et un canal d'instrument (360). Le montage peut être achevé uniquement par l'expansion d'un sac stérile (310) au moyen d'une tension, puis le montage à demeure du sac stérile sur la plaque de couverture de plaque stérile inférieure (330), de telle sorte que la commodité et la rapidité sont obtenues, la situation dans laquelle un composant de transmission et d'autres composants de connecteur sont affectés par des rides formées par le sac stérile (310) est évitée, la résistance de transmission aux articulations peut être réduite, des risques de sécurité potentiels provoqués par un enroulement accidentel des rides par un composant mobile sont évités, et le positionnement et le montage d'un instrument chirurgical (203) peuvent être aidés.
