Eye marker: Cannula protective cap with integrated eye marker ''AB-Marker"

Abstract

Medical cannula (Fig 1-3), characterized in that the protective cap (1) has a handle on a cannula (2), a conical tip (3) and a marker attached to the tip (4), which marks and indicates the orientation of the cannula tip with respect to an anatomical structure, in particular the eye.

Description

Technical area:

[0001] The invention relates to a cannula protective cap ( Fig. 1-3) with integrated marker (4) for fixing or marking the surgical area (eye marking) for medical use. State of the art:

[0002] Numerous medical cannulas are known in the state of the art, but a combination device is lacking that allows the physician to visually and immediately determine the cannula's alignment—for example, with regard to the correct puncture direction or position relative to sensitive anatomical structures such as the eye. Especially for injections in the facial area (e.g., in aesthetic treatments), millimeter-precise alignment is crucial to avoid injuries. Object of the invention:

[0003] The invention has the task of providing a cannula ( Fig. 1-3) with an integrated eye marker (4) to facilitate safe and visually supported alignment for marking - puncturing the face or eye, enabling the insertion of the syringe in the second step. This is to be achieved through a simple, cost-effective, environmentally friendly solution that can be integrated into existing production processes. Solution:

[0004] This task is performed by a cannula ( Fig. 1-3) with an integrated eye marker (4) which is placed on the cannula or the cannula hub with two tips (4) (e.g. two tip bodies or one round body, see Fig. 1 and Fig. 2) is attached so that the physician can mark the eye marker / cannula tip relative to the anatomical orientation (on the eye). Special features: • The eye marker has two tips (4) on the cannula ( Fig. 1 - 3) or the cannula attachment. • The marker (4) is designed as a single unit (cannula and marker) made of plastic / metal. • The marker ( Fig. 1-3) marks the exact positioning of the syringe on the eye. • The two tips of the marker (4) on the cannula ( Fig. 1-3) have a precisely defined distance (e.g. 3.0 mm - 4.0 mm) from each other to ensure the mark on the eye so that the tip can be positioned. Advantages of the invention: • Reduces one step for the physician when marking and injecting intravitreal material into the eye. • Reduces the patient’s time on the couch • Simplified marking of the eye for injections near the eye. • Better control and orientation for medical staff. • The combination of cannula and marker results in low manufacturing costs. • More environmentally friendly - The combination reduces a large amount of raw materials (CO2 reduction) Example:

[0005] The cannula protective cap with integrated marker (eye marker) ( Fig. 1-3) for intravitreal injection into the eye are equipped with tips. The physician places the needle cap with a marker on the eye, thus marking the position of the intravitreal injection. He then removes the needle cap with the marker and administers the injection into the eye at the marked location.
