ROBOT ARM APPARATUS Russian patent published in 2015 - IPC A61B17/64 A61B17/66 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. A device for treating bone fractures comprises a number of levers, a number of joint elements, a mechanical device, a controller and a frame. Each of the levers extends from a proximal end to a distal end and is movable in the three-dimensional space. The proximal end of each lever is connected to the frame. Each of the joint elements is connected to the distal end of the respective lever, wherein the joint element encloses and blocks a bone fixation element attached to the respective bone fragment so that each of the levers is connected to the respective bone fragment. The mechanical device makes the lever move for advance each of the levers in relation to the frame. The controller obtains data respective to a desired final position of the bone fragments in relation to each other and controls the mechanical device to advance the levers in relation to each other for achieving the desired final position of the bone fragments in relation to each other. The frame comprises a long element with a number of levers attached thereto. The long element is configured rotatable to rotate a number of levers in relation to the frame. A method of treating the bone fractures involves: attaching a first bone fragment to a first bone fixation element and a second bone element to a second bone fixation element; connecting a distal end of the first lever with the first bone fixation element and a distal end of the second lever with the second bone fixation element; each of the first and second levers extends between the distal end and proximal end connected to the frame; the frame comprises a long element with a number of levers attached thereto; the long element is configured rotatable to rotate the first and second levers in relation to the frame; obtaining the data corresponding to the desired final position of the first and second bone fragments in relation to each other; and controlling the mechanical device to advance the first and second levers in relation to each other to achieve the desired final position of the bone fragments.

EFFECT: inventions enables calculating and controlling the force, direction and rate of the process.
