A soft-tip medical instrument (10, 10 ', 10 ", 10' '') for ophthalmic surgical procedures, comprising: an elongated part (100) comprising a cannula or needle having a distal end (105) and defines a first step (115); and a soft tip (130) defining a second step (134) adapted to engage the distal end of the elongate portion at a coupling site (150); the coupling site (150) is defined between a surface (106) at the distal end of the elongated part and a surface at the proximal end (131) of the soft tip, wherein said surfaces are adapted to abut when the soft tip is coupled to the elongated part; where the coupling site (150) has a surface area (151) greater than a cross-sectional area of the elongated part (100) and is adapted to provide a tongue and groove interlocking connection (120, 121) between the elongated part and the soft tip, characterized in that, the d The diameter of the first step (115) and the second step (134) are the same along the coupling site (150); and the outer diameter of the elongated part and the outer diameter of the soft tip are the same along the coupling site (150). |
