Abstract
A guiding system (1, 101) for guiding the insertion of a needle (2) and a catheter (6) for medical use in a biological tissue, the guiding system (1, 101) comprising: —the needle (2) —the catheter (6) inserted into the needle (2); —an optical fiber (8) provided with at least one optical sensor (10) and inserted into the catheter (6), —a first blocking device (12, 112) for firmly blocking the catheter (6) inside the needle (2).
Claims18
A guiding system for guiding the insertion of a needle and a catheter for medical use in a biological tissue or compartment, the guiding system comprising:
- the needle, which is hollow and is provided with an end portion having an edge delimiting an opening of the needle,
- said opening having a geometric center,
- and said edge comprising a pointed end of the needle;
- the catheter inserted into the needle;
- an optical fiber provided with at least one optical sensor and inserted into the catheter,
- a first locking device for firmly blocking the catheter inside the needle,
- wherein the catheter is provided with an end proximal to the pointed end,
- wherein the optical fiber is in abutment with said end of the catheter,
- wherein the optical sensor is spaced from said end of the catheter by a distance less than or equal to 50 mm,
- wherein the position of the catheter with respect to the needle is such that said end of the catheter is between
- a first position in which the end of the catheter is at the geometric center of the opening of the needle, and
- a second position in which the end of the catheter is at the pointed end of the needle,
- whereby any deformations of the catheter are detected by the optical fiber and the optical sensor during the insertion of the needle, and wherein the first locking device comprises locking means for locking the catheter, and adjustment means adapted to adjust the position of the catheter in a controlled manner with respect the needle, said adjustment means being distinct from the locking means.
