This invention relates to a locking pin that constitutes an improvement over those currently existing on the market. This pin has a novel form of insertion that no other pin in the world has, this being combined with the fact that the two most recent models do not require sophisticated equipment in order to be locked since they are self-locking. The subject matter of this invention is to provide a certain type of pin that is easier to insert in the femur and tibia bones in order to reduce operating times in surgery and the number of pieces required for fitting them, such that patients can obtain a lower-cost product that is less hazardous to their health as they do not have to remain in the operating theatre for extended periods of time. To conclude, the aim of creating the most recent model suggested is to publicise a type of pin that is totally different from those that currently exist on the market by virtue of a novel internal construction, which enables the pin to be locked via the inside of the bone without any special external addition. The only instruments required are an impactor, a de-arming device and two sleeves connected by a tube.
