Abstract

The invention relates to a mechanical arm which comprises an upper arm and a front arm. The upper arm and the front arm are hinged together through the first joint structure; the second joint structure is arranged at the end part of the upper arm and / or the front arm; the first driving mechanism is arranged in the upper arm; the second driving mechanism is arranged in the front arm; wherein the first joint structure comprises a first force releasing device and a first locking piece, the second joint structure comprises a second force releasing device and a second locking piece, and the first driving mechanism and the second driving mechanism apply acting force to the first locking piece and / or the second locking piece through the first force releasing device and / or the second force releasing device. According to the mechanical arm, the force releasing device is arranged in the joint structure, the locking force is amplified, and the mechanical arm can meet the large-load application requirement under the miniature condition.

Description

technical field [0001] The invention belongs to the field of medical technology, and relates to a mechanical arm for surgery. Background technique [0002] In recent years, with the continuous development of medical robotics at home and abroad, medical robotics has become an important branch of the field of robotics, and it is also an important research direction in the field of biomedical engineering. In the medical field, especially in the field of surgical robots, surgical robots can perform some complex surgical actions by precisely controlling the operation of the robotic arm. In addition, in the medical field, there is also a demand for fixed holding of limbs and surgical tools, and the demand for holding force is high. Therefore, different passive arms are designed for existing medical devices according to different holding needs. Whether it is an active manipulator or a passive manipulator, it usually has multiple joints, so that it can realize multi-degree-of-freed...
