Title:
MULTIPLE-DEGREE-OF-FREEDOM PORTABLE MINIMALLY INVASIVE SURGERY ROBOTIC ARM
Document Type and Number:
WIPO Patent Application WO/2023/024600
Kind Code:
A1
Abstract:
A multiple-degree-of-freedom portable minimally invasive surgery robotic arm. A grip joint assembly is used for movably mounting a shaft portion (8) of a grip (5); the grip joint assembly is provided with a first rotational axis (14) and a second rotational axis that are perpendicular to each other, so as to allow the shaft portion (8) to respectively rotate around the first rotational axis (14) and the second rotational axis; the first rotational axis (14) coincides with the axis of the shaft portion (8), and the second rotational axis is perpendicular to an arm component (3); a control mechanism connects the shaft portion (8) and a pull rope joint assembly (12), and is used for transmitting the motion of the grip (5) to the pull rope joint assembly (12); the control mechanism comprises a four-linkage mechanism; the four-linkage mechanism comprises an input member, two push rods (11), and an output member; the two push rods (11) are respectively connected to the input member and the output member; and the input member receives the output motion of the shaft portion (8), and the output member is a part of the pull rope joint assembly (12). A user can control a cutter head joint assembly (2) by means of a wrist joint action of a grip hand, thereby avoiding two-hand operation, and simplifying an operation method.
