As shown in figure (23), for example, a preferred embodiment of the gauge (301) includes a body (302) with a plumb bob (303) mounted to the body (302). The plumb bob (303) hangs from the body (302) under the influence of a local gravitational field. More particularly, the plumb bob (303) is rotatable relative to the body (302) in both a first plane and a second plane, said planes being orthogonal to each other. In use, a connector (322) allows the gauge (301) to be connected to various surgical implements. The position of the indicator needle (315) on the plumb bob (303) is noted with reference to two sets of markings (316 and 317) on the body (302) to allow a surgeon to determine a first angle in a first plane and a second angle in a second plane. In one exemplary application of the invention, the first and second angles are anatomical angles associated with the surgical insertion of prosthetic components.

Dans la forme de réalisation préférée de l'invention, représentée par la figure 23, par exemple, la jauge (301) comprend un corps (302) auquel est fixé un disque (303) de plomb. Le disque (303) de plomb pend par rapport au corps (302) sous l'action d'un champ de gravitation local. Plus particulièrement, le disque (303) de plomb peut tourner par rapport au corps (302) dans un premier et un second plan orthogonaux. A l'utilisation, un connecteur (322) permet de relier la jauge (301) à divers instruments chirurgicaux. La position de l'aiguille indicatrice (315) sur le disque de plomb (303), établie par rapport à deux ensembles de marques (316 et 317) prévues sur le corps (302), permet au chirurgien de déterminer un premier angle dans un premier plan, et un second angle dans un second plan. Dans une forme de réalisation exemplaire, les premier et second angles sont des angles anatomiques associés à l'insertion chirurgicale d'éléments de prothèse.
