Orthopaedics operation robot

Abstract

The invention discloses an orthopaedics operation robot which structurally comprises six parts including a pedestal, a moving platform, two symmetrical five-linkage mechanisms, a polishing and drilling attitude adjustment mechanism and a polishing and drilling part, wherein the pedestal drives the moving platform to do rectilinear motion in the horizontal direction by virtue of a main component, that is, a screw sliding table; the two five-linkage mechanisms are connected in parallel with the polishing and drilling attitude adjustment mechanism; the polishing and drilling attitude adjustment mechanism and the polishing and drilling part are mounted on universal joints by virtue of a polishing and drilling fixed seat, are connected with the five-linkage mechanisms via shafts, and are driven by an independent EC motor, so that the polishing and drilling part has a front-and-back swing degree of freedom to meet the requirement of high-precision accurate execution of various complex actions. The orthopaedics operation robot is high in precision, flexible to operate, and high in isotropy, has no accumulative errors, and is especially suitable for drilling and polishing in a bone surgical operation.

Description

technical field [0001] The present invention relates to a medical robot, in particular to a minimally invasive orthopedic surgical robot; in particular to a minimally invasive surgical robot for performing drilling and grinding operations in orthopedic surgery. Background technique [0002] In minimally invasive orthopedic surgery, such as pedicle screw internal fixation, percutaneous odontoid process screw internal fixation, femoral and tibial intramedullary nail internal fixation, cervical intervertebral disc replacement, etc., all need to be performed according to the precise path and trajectory for drilling and grinding operations. This type of surgery needs to drill and polish the surgical site at the correct position. The therapeutic effect depends heavily on the surgical accuracy. Improper operation can lead to damage to important nerves and blood vessels of the human body, and millimeter errors will bring catastrophic consequences. In severe cases, the patient can b...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, minimally invasive orthopedic surgery robots have a variety of structures, but due to structural deficiencies, there are more or less shortcomings or imperfections such as flexibility, insufficient degrees of freedom, and low precision for complex actions. or insufficient

[0006] This is exactly why the current orthopedic minimally invasive surgery is labor-intensive and takes a long time during the operation, and the quality of the operation varies from person to person, and the difference is quite large.
