Problems solved by technology

For this structure, if full counterweight is required, a large counterweight space is required, resulting in a larger cross-sectional size of the rectangular tube or square tube to be selected.
A ball screw is installed inside a square tube or a rectangular tube as a driving device. The screw nut structure of this mechanism is enclosed inside the square tube. The structure is compact and saves space to a large extent, but it still seems top-heavy The modular screw nut structure is difficult to install, adjust and maintain in the later period. The four directions of the column bear the same moment, without highlighting the key points, and there is still a certain degree of waste

Abstract

The invention discloses a manipulator lifting and rotating connecting structure. The manipulator lifting and rotating connecting structure comprises a standing column, a lifting mechanism and a driving mechanism, the standing column is I-shaped, a sliding groove is formed in the standing column, a connecting block is connected within the sliding groove, the two ends of the connecting block extendout of the sliding groove, one end of the connecting block is connected with the lifting mechanism, and the other end of the connecting block is connected with the driving mechanism. The manipulator lifting and rotating connecting structure achieves the improvement of the rigidity of the system.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a lifting and turning connection structure of a manipulator. Background technique [0002] Minimally invasive surgical robots can reduce the physical labor of doctors during surgery while achieving the purpose of precise surgery. At present, the minimally invasive surgical robots on the market are mainly products of Intuitive Surgical Company of the United States. Its minimally invasive surgical robots are divided into three parts: video cart, surgical trolley and console. The surgical trolley has structures such as bases and columns. In addition, the research and development products of some companies also adopt the form of base and column. Among them, the main structural forms of the column part of the trolley include: closed column and outer drive structure, closed column and counterweight structure, and installation of balls inside square or rectangular tubes. The screw acts...
