Bone nail with smooth trailing end

摘要

A bone nail has a shaft with a leading section and a trailing section, wherein the trailing section includes an end surface having at least one depressed portion and at least one elevated portion. The transition between one of the depressed portions and the adjacent elevated portion is smooth. The end surface is formed so as to transmit rotational forces as well as translational forces from a medical device to the shaft of the bone nail, when the medical device is coupled at the end surface to the trailing section of the bone nail.

主权项

1. A bone nail comprising:
a shaft extending along a longitudinal axis with a leading section adapted to be introduced first into a body during an implantation of the bone nail, and a trailing section adapted to be introduced last into the body during an implantation of the bone nail, the trailing end section terminating in an outwardly facing end face defined by a circumferential surface extending transverse to the longitudinal axis; wherein the trailing section circumferential surface is continuously curved in a direction parallel to the longitudinal axis, the surfaces transverse to the longitudinal axis describe a sinusoidal-like waveform along the circumferential surface, having a depressed portion and an elevated portion in the direction parallel to the longitudinal axis, wherein a transition between the depressed portion and the elevated portion is a smooth transition.
