Definitions
- cannula cuts which can reduce the punching tendency. Usually, these cuts work up to a certain diameter of the cannula. The larger and thinner the cannula, the more difficult it becomes to constructively prevent the punching of particles.
- the cannula tip is bent inwards in the direction of the cannula longitudinal axis or central axis.
- This has the additional advantage that the tip-distant part of the cut is to a certain extent in the shadow of the cannula tip and thus no longer or to a lesser degree cuts into the tissue or into the membrane.
- the above-described angles between the cutting line and the longitudinal axis of the cannula, between the second and third cutting surfaces and between the first cutting surface and the cannula longitudinal axis are to be understood such that the angles are in the state of the unbent cannula.
- Figures 3a and 3b are side views of the embodiments of Figures 2 and 1;
- the second and third cut surfaces intersect in a section line S, which is substantially perpendicular to the cannula longitudinal axis M.
- the angle a which the cutting line S and the cannula longitudinal axis M include, is between 45 ° and 135 °.
- a further advantage of the cannula according to the invention consists, as already explained above, in that the hooking lines of the tip do not run off into a pointed triangle with very thin wall thicknesses (as is the case in the prior art), but to a cutting edge which overhangs the entire cannula wall thickness is sufficient and accordingly extremely stable. This does not result in the cannula according to the invention curling hooking on the cannula tip when the cannula tip impacts the bottom plate of a port.
