Percutaneous introducer, particularly for flexible drainage tubes and with various profiles

A kit for inserting surgical drainage tubes, comprising a percutaneous introducer comprising a main body comprising a longitudinally extended tubular element arranged in the distal portion of said main body, said longitudinally extended tubular element comprising a terminal arranged at a distal end of said longitudinally extended tubular element;

• a sliding body comprising a longitudinally extended obturator arranged in a distal portion of said sliding body, said longitudinally extended obturator being inserted and being movable longitudinally within said longitudinally extended tubular element of said main body, said longitudinally extended obturator comprising a cutting blade arranged and fixed at a distal end of said longitudinally extended obturator;
• and a return and positioning spring adapted to return said cutting blade to a retracted position within its seat, following a controlled exit of said cutting blade through a passage slot arranged in said terminal of said longitudinally extended tubular element, and a longitudinally extended positioning device configured to guide an insertion of a surgical drainage tube through a percutaneous access, wherein said longitudinally extended positioning device is a longitudinally extended monolithic body having a longitudinally extended seat open upward for the accommodation of said surgical drainage tube, said seat comprising a plurality of raised portions arranged along its internal surface, a pair of flexible wings configured to retain said surgical drainage tube within said seat, and a distal terminal configured to facilitate the insertion of said positioning device inside said percutaneous access.

A percutaneous introducer comprising:

• a main body comprising a longitudinally extended tubular element arranged in the distal portion of said main body, said longitudinally extended tubular element comprising a terminal arranged at a distal end of said longitudinally extended tubular element;
• a sliding body comprising a longitudinally extended obturator arranged in a distal portion of said sliding body, said longitudinally extended obturator being inserted and being movable longitudinally within said longitudinally extended tubular element of said main body, said longitudinally extended obturator comprising a cutting blade arranged and fixed at a distal end of said longitudinally extended obturator;
• and
• a return and positioning spring adapted to return said cutting blade to a retracted position within its seat, following a controlled exit of said cutting blade through a passage slot arranged in said terminal of said longitudinally extended tubular element, and further comprising a lid adapted to close a first opening of said main body which is arranged in a proximal face of said main body, and also further comprising a sliding carriage disposed in a second opening of said main body arranged in a distal face of said main body, said sliding carriage being longitudinally movable within said main body, said sliding carriage comprising a rotating mechanism engaged on a rib of said tubular body and is adapted to load and release said sliding body.
