Abstract

The invention discloses a quick changing device for minimally invasive surgery instruments. The quick changing device comprises an instrument box base, a fastener structure and an isolating assembly, wherein the instrument box base and the fastener structure of a quick changing base of a quick changing body are used for being connected with an instrument box, the isolating assembly is arranged between the instrument box base and the quick changing base, the quick changing base is fixedly connected with one end of a rotating connection shaft by threads, and the other end of the rotating connection shaft is arranged on the tail end of hands of a robot by a bearing in a rotating manner; and a plurality of self-connected driving assemblies and a plurality of instrument transmission assemblies are arranged on the quick changing base. According to the quick changing device, the safety of the robot is enhanced, the disinfection frequency of the robot body is decreased, and the medical cost is lowered.

Description

technical field [0001] The invention relates to a quick replacement device for a minimally invasive surgical instrument, in particular to a quick replacement device for a surgical instrument for a minimally invasive surgical robot in the thoracic and abdominal cavity. Background technique [0002] Minimally invasive surgery refers to a type of surgical operation performed using modern medical equipment such as thoracoscopes and laparoscopes and supporting equipment. It is only in the past ten years that minimally invasive surgery technology has appeared and been widely used in the medical field. Compared with traditional open surgery, minimally invasive surgery pays more attention to the improvement and rehabilitation of the patient's psychology, society, physiology (pain), mental outlook, and quality of life. , less bleeding, less pain, faster recovery and other advantages, it has become the preferred surgical method for doctors and patients. However, in minimally invasive...
