Problems solved by technology

For the slender robotic arm with multiple connecting arms in series, this torsional deformation will generate a large error accumulation at the end, thereby reducing the end accuracy of the surgical robot.
[0005] In addition, the structure of this connecting arm also brings some difficulties to the maintenance of the flexible transmission assembly

Abstract

The invention discloses a mechanical arm and a robot with the same. The mechanical arm comprises at least one connecting arm; the connecting arm is in a rod shape and is provided with an inner cavity extending in the length direction of the connecting arm, wherein the section, perpendicular to the length direction, of the inner cavity is at least partially of a closed structure. According to the mechanical arm, due to the fact that the section of the inner cavity of the connecting arm is at least partially of the closed structure, smooth transmission of force flow and continuity of force can be guaranteed, and the connecting arm can meet the requirements for rigidity and torque only through the relatively small wall thickness and the relatively simple structure.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a mechanical arm and a robot with the same. Background technique [0002] Medical and surgical micro-instruments have the advantages of accurate positioning, stable operation, strong dexterity, large working range, and are not afraid of radiation and infection, and are widely used in various operations. Surgical robot is one of the medical surgical instruments. During the operation, the medical staff pushes the patient's bed to the surgical robot. The multiple robotic arms of the surgical robot move to the patient's body through control, and pass through the patient's skin. Set the small hole to complete the corresponding operation. During the operation, the robotic arm can be rotated and inserted around the preset small hole on the patient, and the rotation point of the robotic arm around the fixed axis is called the RCM (Remotecenter of motion) point. [0003] Previous su...
