Abstract

The invention discloses a driving support for a robot used for aiding minimally invasive surgery, wherein a base part comprises a frame and an upright post; a connecting surface which is provided with an opening is arranged on one side of the upright post; the upright post is connected with a rectilinear motion module; a lead screw and a slide seat are connected to the rectilinear motion module; an adjusting frame part comprises an adjusting frame, a guide rail seat, a first sliding guide rail which is connected to the guide rail seat, and a slider; the lower part of the guide rail seat is provided with a three-step lug boss; a bearing structure and the adjusting frame are sleeved on the central lug boss in turn; one end of the adjusting frame is inserted into the opening of the connecting surface; a beam part comprises a beam; one side of the beam is connected with the slide seat, and an input wheel and an output wheel the upper part of which is provided with a cylindrical lug boss are arranged on the other side of the beam; the first slider is fastened and fixedly connected with the input wheel; a telescopic body part comprises a telescopic seat; the bottom of the telescopic seat is provided with a hole; and the cylindrical lug boss is inserted into the hole at the bottom of the telescopic seat. The driving support guarantees the motion precision, the system rigidity and the safety of the robot.

Description

Technical field [0001] The invention relates to a medical device in the field of minimally invasive surgery, which can assist surgeons in performing minimally invasive surgery operations, in particular to a robotic active support for assisted minimally invasive surgery suitable for minimally invasive surgery operations in the thoracic cavity and abdominal cavity . Background technique [0002] Minimally invasive surgery represented by laparoscopy is known as one of the important contributions of medical science to human civilization in the 20th century. Minimally invasive surgery refers to the use of slender surgical tools to penetrate into the body through tiny incisions on the surface of the body to perform operations. Operational. Compared with traditional open surgery, it has the advantages of small surgical incision, less bleeding, less postoperative scars, and faster recovery time, which greatly reduces the pain suffered by patients; therefore, minimally invasive surgery is...
