A segment for a holding arm for positioning a medical instrument or a medical appliance, comprising:
- several node structures;
- a strut that rigidly connects two of the several node structures to each other;
- the strut having flat structures that are joined to one another;
- wherein at least two of the flat structures are joined to each other with a form fit;
- and
- wherein one of the flat structures has a tenon, which engages in a corresponding recess in another of the flat structures.
A segment for a holding arm for positioning a medical instrument or a medical appliance, comprising:
- several node structures;
- a strut that rigidly connects two of the several node structures to each other;
- the strut having flat structures that are joined to one another;
- wherein the flat structures each have a narrow and elongate shape;
- wherein the flat structures comprise an inner structure, an outer structure, and a connecting web;
- wherein a first lengthwise edge of the connecting web is joined to the inner structure, and a second lengthwise edge of the connecting web is joined to the outer structure;
- and
- wherein the inner structure, the connecting web, and the outer structure together form an I-shaped cross section of the strut, or the inner structure, the connecting web, a second connecting web, and the outer structure together form a quadrilateral cross section of the strut.
A segment for a holding arm for positioning a medical instrument or a medical appliance, comprising:
- several node structures;
- a strut that rigidly connects two of the several node structures to each other;
- the strut having flat structures that are joined to one another;
- wherein the node structures are each substantially ring-shaped and have grooves on their outer circumference, each of the grooves are configured to receive an end of one of the flat structures.
A segment for a holding arm for positioning a medical instrument or a medical appliance, comprising:
- several node structures;
- several struts each rigidly connecting two of the several node structures to each other;
- at least one of the several struts having a first flat structure extending from a first of the several node structures to a second of the several node structures, and a second flat structure extending from the first of the several node structures to the second of the several node structures;
- and
- the first flat structure is joined to the second flat structure by a connecting structure extending substantially from a first end of the first and second flat structures to a second end of the first and second flat structures;
- wherein at least one of the first flat structure and the second flat structure has a shape of a cutout of a lateral surface of a cylinder or a cone.
