A retractor for surgery according to various implementations comprises a handle, an operating portion, and a curved body. In a side view, the handle, the curved body, and the operating portion each define a mean line, wherein:

Retractor

Joint prosthesis () with removal device comprising a first portion () suitable to be implanted in a bone structure and suitable to couple with a second portion (), characterised in that said second portion () houses within it a removal element () suitable to interact with at least one of said first and second portions () and in that said removal element (), is configured to be operated in translation with respect to the second portion (), and to generate a detachment force such as to uncouple the first portion () from the second portion () of the joint prosthesis ().

Joint prosthesis with removal device

Prosthesis for joint shoulder reconstruction comprising a joint head shaped to provide a spherical type coupling with a concave joint element of a glenoid component. The joint head includes a metallic core and a joint cap made of a plastic material provided with a cavity insertable on an insertion element of the core along a longitudinal direction. The insertion element and the cavity are configured to define shape-coupling means operating by elastic deformation such as to secure the joint cap to the core along the longitudinal direction. A plurality of penetration elements are arranged between a plate of the core and a coupling surface of the joint cap to define an anti-rotation mechanism of the joint cap on the core.
