Abstract
A method for moulding an elongate articulated bending section body (4) for a medical device including a number of segments (7) interconnected via a number of hinge members (8). The method includes the use of a mould having a first number of sub-cavities where each of the sub-cavities has at least one external fluid inlet through which a liquified plastic material is injected into the mould. The sub-cavities are so distributed that each sub-cavity is separated from another sub-cavity by an odd number of sub-cavities without an external fluid inlet.
Claims14
A method for molding a bending section body for a medical device, the method comprising:
- injecting a liquified plastic material through fluid inlets of a mold to form segments and hinges of the bending section body, the hinges formed in passages of the mold, and the segments formed in sub-cavities of the mold, the segments being interconnected by the hinges,
- wherein the sub-cavities are positioned parallel to each other and along a length of the mold and comprise fluid-inlet sub-cavities and inlet-free sub-cavities, each of the fluid-inlet sub-cavities being separated from another of the fluid-inlet sub-cavities by one of the inlet-free sub-cavities,
- wherein said injecting comprises injecting the liquified plastic material into the fluid-inlet sub-cavities solely through the fluid inlets and into the inlet-free sub-cavities through the passages,
- wherein a longitudinal center plane traverses the sub-cavities, and
- wherein the fluid inlets are offset in alternating directions from the longitudinal center plane.
