Description

Fracture tension and restoration device for orthopedic surgery {A BONE DRAW AND RESTORATION SYSTEM FOR ORTHOPEDICS}

The present invention relates to a device for tensioning the fractured bone of the human body in the longitudinal direction and to restore it to its original position. In particular, after tensioning the fractured portion, it is easily and safely restored to its original position by adjusting it by moving up and down, back and forth, left and right. It relates to an orthopedic fracture tension and restoration device that can be made.

In general, a lot of accidents that the bones of the human body are fractured by an external impact, etc., in particular, the bones of the arms and legs are often fractured. The primary treatment for fractures of bones is to restore the fractures to their original state, and the restoration of these bones is carried out by a skilled expert using hands.

That is, after pulling the fractured bone by pulling the leg or arm in the fractured state, the fractured part of the hand was moved to the correct position by moving away from the fractured position.

However, in order to tension the fractured bone, this conventional method requires not only a lot of force because the arm or leg needs to be pulled to tension the fractured and displaced area, but also one person cannot tension the fractured bone. There was a hassle to work with.

In addition, because the fractured part is in tension, it is difficult for a professional worker to fit into the right position at once due to the sense of the hand, and not only consumes a lot of work time, but also inadvertently damages bones or nerve tissues due to inadequate working.

In particular, there is a problem in that it is necessary to repeatedly perform the above-mentioned tensioning work and the work to fit in place because the fractured areas can not be fit at a time by the sense of the hand.

In recent years, the left and right end portions of the fractured bones of the arms or legs are fixed to the fixing members, and the fractured portions are tensioned by moving the fixing members on both sides to the outside. This method can simplify the tensioning of the bones, but it is necessary to adjust the bones to the right position after the fractured part is tensioned. The cause was not solved.

The present invention has been researched and developed in order to solve the above problems, the operation of restoring in the tension and the correct position by a control device that is moved and rotated up and down, front and rear, left and right fractured areas of the arm or leg in one device There is a technical problem to be able to execute sequentially.

Another technical problem of the present invention is that by operating a control device without the help of several people when tensioning the bone of the fractured site, there is a technical problem to enable one operator to simply and quickly pull the work.

Another technical problem of the present invention is to tension the bone of the fractured site, and to be able to easily work without safety accidents even if not skilled in the restoration work to fit in place.
