Repeated use trocar-needle insertion instrument and loading tool
First Claim
1. A repeated use trocar-needle insertion gun (RUTI) operating in association with a loading tool, comprising:
- a needle portion of the RUTI being configured for gripping a trocar-needle before insertion into a bone, and for release of the trocar-needle upon insertion into the bone,a front portion of the RUTI being configured for adjusting insertion-depth of the trocar-needle into the bone, and for protecting the trocar-needle prior to release,a rear portion of the RUTI having a shooting mechanism operative for shooting the trocar-needle, and a catch adapted for retaining the shooting mechanism, and for releasing the shooting mechanism when triggered for shooting, and the front portion being releasably coupled to the rear portion, the rear portion comprising;
a housing having a housing inside, a housing outside and a housing bottom,at least one spring disposed inside the housing and residing in a first compressed condition associated with a loaded state of the RUTI before shooting the trocar-needle, and in a second released condition associated with a spent state of the RUTI after shooting the trocar-needle,at least one open loading opening being accommodated in the bottom of the housing of the RUTI to provide access therethrough, from the outside to the inside, for coupling the loading tool with the at least one spring, anda loading tool configured for coupling with and operative for reloading the RUTI in situ from the spent state to the loaded state via the at least one loading opening.

Abstract
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.
