Abstract
The present invention relates to a new bevel or grinding for a punch-reducing cannula, i.e. a cannula which reduces punching particles, and, in particular, to a punch-reducing cannula having a beveled or ground end as well as to a method for manufacturing a cannula which reduces punching particles.
Claims17
A cannula having a longitudinal cannula axis and a cannula tip with a beveled end which comprises a basic grinding defining a first ground section and further comprises two section grindings, wherein the two section grindings respectively define second and third ground sections which intersect at an intersection line, wherein the intersection line and longitudinal cannula axis include an angle between 70° and 110°.
A method for manufacturing a cannula with a beveled end, in particular a cannula according to any one of the preceding claims, comprising the steps of:
- a) providing a cannula with a longitudinal cannula axis;
- b) adding a basic grinding defining a first ground section;
- and
- c) adding two ground sections which respectively define second and third ground sections;
- wherein the second and third ground sections intersect at an intersection line which is essentially perpendicular to the longitudinal cannula axis and wherein the intersection line and the longitudinal cannula axis include an angle between 70° and 110°.
