主权项

1. A sterilized, integrated, one time use disposable visualization needle, comprising:
an elongate tubular needle, extending along a longitudinal axis between a proximal end affixed to a handpiece and a distal end having a sharpened tip; an elongate optical element extending through the needle; wherein an outer diameter of the distal end of the elongate optical element is configured to have a bias against an inner diameter of a point of the sharpened tip of the needle, the bias configured to press the distal end of the elongate optical element against the distal end of the elongate tubular needle to provide blunting of the tubular needle.
