Description

Device set for bone bonding {OSTEOSYNTHESIS PLATE SET}

The present invention relates to a set of devices for bone joining, and more particularly, to a set of devices for bone joining implemented to increase convenience of use and product stability through structural improvement.

In general, a bone plate is a fixing plate used to stabilize bone fractures or injuries, and weakened bone parts.

These bone plates have a structure in which holes having certain shapes are formed to accommodate fixing elements such as bone screws that are fixed to target portions of bones.

In particular, the fibula is a thin and long bone parallel to the outside of the tibia (tibia). It plays a role in stabilizing the joint), but fractures may occur due to an accident or impact during exercise, and by fixing the bone plate using a fixing element such as a bone screw on the surface of the fibula at the fracture site, preventing the fractured bone from escaping. and enable osteosynthesis.

However, in using the conventional bone plate, there was inconvenience in that the user could not use the bone fixing elements in various ways and forms using specific holes of the bone plate in specific situations, and improvement is required. .

On the other hand, the above-mentioned background art is technical information that the inventor possessed for derivation of the present invention or acquired in the process of derivation of the present invention, and cannot necessarily be said to be known art disclosed to the general public prior to filing the present invention. .
