Problems solved by technology
[0004] The present invention is to solve the inconvenient operation and low flexibility of the existing hand-controlled minimally invasive surgical instruments. The rotation and yaw motions do not have self-locking properties. The introduction of human-like wrist joints makes the end effector kinematically coupled. Can not be quickly replaced and other problems, and then propose a hand-controlled flexible minimally invasive surgical instrument with self-locking and quick replacement functions

The invention discloses a manually-controlled flexible minimally-invasive surgical instrument with self-locking and quick replacement functions, and relates to the technical field of minimally-invasive surgical medical equipment for thoracic and abdominal cavities. The instrument solves the problems that existing manually-controlled minimally-invasive surgical instruments are inconvenient to operate and low in flexibility and do not have the self-locking function during rotation and deflection motion, motion coupling exists in end executors through introduction of imitated human wrist joints,and the end executors cannot be quickly replaced. The instrument comprises an end executor, an operating rod, a motion control device and an instrument shell; the end executor comprises a first end small claw quick replacement connector, a second end small claw quick replacement connector, a flexible joint connector, an end small claw rotation shaft, a flexible joint and two end small claws; the motion control device comprises a rotation motion locking mechanism, a deflection motion locking mechanism, an opening and closing motion control mechanism, a base and a steel wire guiding wheel set. The instrument is used for minimally invasive surgery of the thoracic and abdominal cavities.
Description
technical field [0001] The invention relates to the technical field of medical equipment for minimally invasive surgery in the thoracoabdominal cavity, in particular to a hand-controlled flexible minimally invasive surgical instrument with self-locking and quick replacement functions, which assists an assistant in pulling tissue. Background technique [0002] Minimally Invasive Surgery (MIS) represented by laparoscopy is known as one of the important contributions of medical science to human civilization in the 20th century. Its application makes some surgical operations bid farewell to the traditional open surgery mode. Minimally invasive surgery means that the surgeon cuts 2-4 small incisions of 5-10mm on the patient's body surface, inserts surgical instruments into the human body through the patient's tiny incisions, and uses visual monitoring equipment and dexterous surgical instruments to treat the lesion. site for diagnosis or treatment. Surgical instruments, as the e...
