APPARATUS FOR CREATING PORTAL SITES USING A BLADE AND NEEDLE

摘要

An apparatus comprises a barrel comprising an interior and an open end. The barrel is configured for engaging a needle along a longitudinal length where the engaged needle extends a distance past the open end. A rod mechanism is disposed within the interior for longitudinal movement and is configured for joining a knife having a blade end where the joined knife is disposed within the interior with the rod mechanism in a retracted position. The blade end extends a distance past the open end with the rod mechanism in an extended position. A spring mechanism engages with the rod mechanism and urges the rod mechanism to be in the retracted position. A plunger device engages with the rod mechanism and applies a force to the rod mechanism to compress the spring mechanism and move the rod mechanism to the extended position.

主权项

1. An apparatus comprising:
a barrel member comprising an interior space and at least one open end, said barrel member being further configured for engaging a needle device along a longitudinal length of said barrel member where the engaged needle device extends a first distance exteriorly past said one open end; a rod mechanism being disposed within said interior space and being configured for longitudinal movement within said barrel member, said rod mechanism being further configured for joining a knife device having a blade end where the joined knife device is disposed within said interior space with the blade end interior to said open end with said rod mechanism in a retracted position, and the blade end extends a second distance exteriorly past said one open end with said rod mechanism in an extended position, said second distance being a portion of said first distance; a compression spring mechanism being in engagement with said rod mechanism, said compression spring mechanism being configured for urging said rod mechanism to be in said retracted position within said barrel member; and a plunger device being in engagement with said rod mechanism, said plunger device being configured for applying a user supplied force to said rod mechanism to compress said compression spring mechanism and move said rod mechanism to said extended position.
