Summary of the invention

The purpose of this utility model provides a kind of automaticity height, and reduction is accurate, efficient and make patient's action put in order the bone fixed mount easily.

For achieving the above object, the technical scheme that this utility model adopted is:

A kind of whole bone fixed mount, comprising: stand, body frame, support body and locking pin; Body frame is installed on the stand, and two swivel beckets about body frame is divided into have symmetric eight arcuate sockets on the swivel becket, and support body is installed in the arcuate socket, and locking pin is installed on the support body; Its characteristics are: the swivel becket of the right-hand member in the body frame is connected to form successively by motion ring, vertical motion ring, gear ring, pressure ring four parts, the inwall of motion ring has depression, the vertical motion ring slides up and down with the motion ring in the depression of motion ring and is connected, have symmetric eight arcuate sockets on the gear ring, pressure ring is positioned at the gear ring left end, pressure ring is fixedlyed connected with vertical rotating ring by bolt and gear ring is pressed between pressure ring and the vertical moving rotating ring, have aperture on the pressure ring wall, design has little moving gear and gear ring to be connected with a joggle in the aperture; Body frame is installed on the stand by six universal joints, design has screw in the universal joint, universal joint is installed in the movable block on the stand, have dovetail groove on the movable block, design has dovetail protruding on the swivel becket of body frame, dovetail is protruding to be inserted in the dovetail groove, and the bolt on the stand passes screw, and universal joint is slidingly connected by bolt on the body frame and stand.

In such scheme, stand is divided into left and right sides two parts, and left and right sides two parts stand connects by bolt.

In such scheme, support body is a circular arc.

The utility model has the advantages that: because the body frame in this utility model is installed on the stand by six universal joints, so body frame can arbitrarily be adjusted direction, can realize the function of whole bone, do not need by manpower stretch, para-position, operation tube is single, and strength is big, degree of accuracy is higher, and support body is a circular arc, because volume is little, is fixed on that the patient takes action conveniently on the long bone of extremity.
