A single shot trocar-needle insertion instrument is configured for repeated use. The repeated use trocar-needle insertion gun (RUTI) operates in association with a loading tool, which for reloading, is coupled with the RUTI via a loading opening. The loading tool reloads the RUTI without requiring disassembly of the shooting mechanism. The loading opening is provided either ready open, or closed but openable in situ, where the insertion of the trocar-needle is administered. It is possible to implement a RUTI by entering a loading opening in an existing single shot trocar-needle insertion instrument (SSTI). After reloading the RUTI by help of the loading tool, a catch is operated, and, after mounting a trocar-needle and a front portion, the RUTI is returned to operative condition.
