Interlocking two-part sewing needle for double loop stitching

An interlocking two-part sewing needle comprising:

• a first needle portion formed from a hollow tube with an internal bore that extends from a leading end of the first needle portion to a trailing end of the first needle portion to provide open ends;
• a channel located at the trailing end of the first needle portion and including a bottom located between a pair of shoulders that are separated from one another by a first space;
• and a needle tip provided at the leading end of the first needle portion;
• a second needle portion configured to be removably connected together with the first needle portion by inserting a leading end of the second needle portion into the internal bore via the trailing end of the first needle portion and then sliding the second needle portion at least partially through the internal bore;
• a channel crimp provided in a portion of the channel wherein a portion of the shoulders located at the channel crimp are separated by a second space that is smaller than the first space such that the shoulders contact the second needle portion at the channel crimp and align the second needle portion with the internal bore;
• and
• a stop crimp that constricts the internal bore and exerts a compressive force on the second needle portion for resisting movement of the second needle portion through the internal bore beyond the stop crimp.

A method of using a needle comprising the steps of:

• providing a two-part sewing needle comprised by a first needle portion having a needle tip;
• a second needle portion configured to be inserted into the first needle portion for removably connecting the first needle portion and the second needle portion together;
• and a needle receiver formed in the first needle portion and configured to receive the second needle portion when the second needle portion is inserted into the first needle portion, the needle receiver including:
• one or more non-resistance sections, each configured to exert only a friction force on the second needle portion when the second needle portion is inserted into the needle receiver;
• and a needle interlock having one or more resistance sections, each configured to exert a compressive force on the second needle portion when the second needle portion is inserted into the needle receiver;
• removably connecting the first needle portion and the second needle portion together by inserting the second needle portion into the needle receiver such that a friction force is exerted onto the second needle portion by one of the one or more non-resistance sections;
• and
• with one of the one or more resistance sections, exerting a first compressive force on the second needle portion that is greater than the friction force exerted on the second needle portion.
