Abstract

Medical or engineering instrument, such as an injection needle, for feeding a solution through a pipe into a desired location. The instrument comprises a pipe (1) into which a partition strip (2) is inserted. At the top end of the pipe, the extremity of the partition strip has a sharp cutting edge, so as to prevent the damage usually caused by the walls of a bevelled pipe making up an injection needle. This partitioned pipe is applied to a medical instrument such as an injection needle or trocar.
