More Information
Summary:The present invention relates to an asymmetric rolling joint device for a surgical tool and, more specifically, to an asymmetric rolling joint device for a surgical tool, which asymmetrically forms contact rolling surfaces of joint links facing each other to increase traction force. To this end, the asymmetric rolling joint device for surgical tool comprises: a first joint link part forming a joint of a surgical tool; and a second joint link part in rolling contact with the first joint link part. The contact rolling surface, in which the first joint link part and the second joint link part are in rolling contact with each other, is formed asymmetrically, thereby increasing traction force in comparison with a symmetric manner. 본 발명은 수술도구의 비대칭 구름 관절 장치에 관한 것으로서, 보다 상세하게는 서로 마주보는 관절 링크의 접촉 구름면을 비대칭으로 형성시킴으로써 견인력을 증대시키는 수술도구의 비대칭 구름 관절 장치에 관한 것이다. 이를 위해 수술도구의 관절을 형성하는 제1 관절 링크부, 제1 관절 링크부와 구름 접촉하는 제2 관절 링크부를 포함하며, 제1 관절 링크부와 제2 관절 링크부가 서로 구름 접촉하는 접촉 구름면이 비대칭으로 형성됨으로써 대칭에 비해 상대적으로 견인력을 증가시키는 것을 특징으로 하는 수술도구의 비대칭 구름 관절 장치가 개시된다.
