The set of locking and pressurizing connection holes and the set of guide pin positioning holes are all set on the bone plate body. The locking bone plate is easy to install. The locking and pressurizing connection holes on the bone plate body can be used with ordinary bone screws or locking bone screws to fix the bone plate. The guide pin positioning holes at both ends are designed to be used with ball-head fixation pins from a general surgical instrument kit. The ball-head fixation pins can be quickly inserted using a medical electric drill to pre-fix the bone plate. After the locking bone screws are inserted, the fixation pins can be quickly removed with an electric drill, simplifying the installation process of the bone plate. At the same time, the guide pin positioning holes can also be used for binding and ligating complex fractures.

[0004] In existing technologies, after the locking screws are implanted, the fixation pins are quickly removed with an electric drill, which simplifies the installation process of the bone plate. At the same time, complex fractures can be ligated through the guide pin positioning holes. However, existing bone plates cannot be effectively guided and have insufficient stability when drilling.
