PREFERRED EMBODIMENT OF THE INVENTION

[0064] Some particular examples of devices according to the present invention are described below, making reference to the attached figures wherein the different parts that composed it can be observed.

FIRST EXAMPLE

[0065] FIGS. 1a and 1b show a first example of a metallic ring (2) according to the invention which has a rectangular cross section. As can be seen, the rectangle constituting the cross section has a certain inclination, in such a way that the upper surface of the metallic ring (2) has a conical surface. This configuration is necessary for a good coupling with the coupling ring (32), as will be explained later. The dimensions of this metallic ring (2) can range from 11 mm to 24 mm.

[0066] FIGS. 2a and 2b show the locking element (3) which consists of the lens (31) and the coupling ring (32). The lens (3) has a convex shape similar to the lenses commonly used in this field. The coupling ring (32), on the other hand, has an essentially rectangular cross sectional shape with a cavity (321) on the lower side, which also has a rectangular shape which is complementary to the rectangular shape of the metallic ring (2) described above. In other words, the cavity (321) forms a rectangular-shaped recessed channel that runs along the entire circumference of the lower side of the coupling ring (32). As can be seen, the curvature of the lens (3) causes the channel formed by the cavity (321) of the coupling ring (32) to be oriented with a certain inward inclination. In addition, the coupling ring (32) has magnetic properties.

[0067] FIGS. 3a and 3b show the process of coupling the locking element (3) to the metallic ring (2). It can be observed that the metallic ring (2) fits perfectly into the channel formed on the bottom surface of the coupling ring (32). The magnetism of the coupling ring (32) attracts the metallic ring (2), thus preventing it from being unintentionally uncoupled.

SECOND EXAMPLE

[0068] FIGS. 4a and 4b show a second example of a metallic ring (2) according to the invention which has a circular cross section. It would therefore be a ring (2) very similar to the well-known Flieringa ring.

[0069] FIGS. 5a and 5b show a second example of the locking element (3) wherein the coupling ring (32) has a semicircular cross section cavity (321). Therefore, in this case, the lower surface of the coupling ring (32) has a semicircular channel that runs along its entire circumference. Also, in this example, the semicircular channel formed by the cavity (321) of the coupling ring (32) is oriented with a certain inward inclination, a consequence of the very curvature of the lens (31) to which it is fixed. As in the first example, the coupling ring (32) has magnetic properties. Finally, FIGS. 6a and 6b show the coupling of the locking element (3) on the metallic ring (2) of this second example of the device (1) according to the invention.

THIRD EXAMPLE

[0070] FIG. 9 shows a third example of a device of the invention, with a metallic ring (2) and a locking element (3), in which the connection between these components is a sealed connection.

[0071] The sealed connection consists of connection by means of a material of elastomeric nature of the coupling ring (32) with the metallic ring (2). For this purpose, the coupling ring (32) is made of an elastomer material, preferably medical silicone or polyurethane.

FOURTH EXAMPLE

[0072] FIG. 12 shows an example of a device of the invention with a metallic ring (2) and a locking element (3), in which the joint between these components is a mechanical connection. In this example, the metallic ring (2) has grooves (40) and the coupling ring (32) has protrusions (41), in such a way that the metallic ring (2) can be fixed and/or sealed with the coupling ring (32).

FIFTH EXAMPLE

[0073] FIG. 13 shows an example of a device of the invention with a metallic ring (2) and a locking element (3), in which the connection between these components is a magnetic connection as described above.

SIXTH EXAMPLE

[0074] FIGS. 16 and 17 show an example of a coupling ring (32) of a locking element (3) of a device of the invention to which a surgical lens (50) has been adapted. FIGS. 14 and 15 show only the coupling ring (32) from FIGS. 16 and 17, which can be fitted with various types of surgical lenses.
