DEVICE FOR EXTERNAL ORTHOPEDIC FIXATIONS Russian patent published in 2019 - IPC A61B17/62 A61B17/64 

FIELD: medicine.

SUBSTANCE: device for external orthopedic fixations comprises one or more frames which have a substantially or partially annular shape and are suitable for being arranged around a limb to surround it at least partially. One or more rods are fixed to at least one frame of said one or more frames by means of at least one locking mechanism provided with at least two jaws which, when they are closed, tighten the locking mechanism to a portion of the frame by exerting a prevalently axial force. Said jaws are closed by means of a cam mechanism suitable for being actuated by rotating at least one lever adapted to be pivoted to a first jaw of at least two jaws and provided with one or more cam surfaces cooperating with at least one surface of the second jaw of at least two jaws. Said at least two jaws of the locking mechanism comprise one or more seats for one of said one or more rods, so that when at least two jaws are closed and tightened on the frame, one or more seats are tightened on a portion of the rod, thereby preventing a relative movement of the rod with respect to at least one axis of the locking mechanism.

EFFECT: invention provides a device that is easy to use, permeable to X-rays, speeds up and simplifies the procedures for installation or removal of the device around the limb.
