A dilator (10) formed with a truss (16) with a pair of spaced-apart end surfaces (20, 22) that provides a restoring force therebetween if forced toward one another, this restoring force provided by a resilient band (30a) extending between the opposite ends (70a, 706) of the truss (16) with a plurality of notches (43a, 43b, 43c) at each end thereof. The notches (43a, 43b, 43c) exceed at least a third of the thickness of the band (30a). A second and similar band (30a) may also be provided in the truss (16).

Ecarteur (10) doté d'un renfort (16) comportant une paire de surfaces d'extrémité espacées (20, 22) qui produisent une force de rappel si on applique sur elles une force tendant à les rapprocher l'une de l'autre, cette force de rappel étant obtenue grâce à une bande élastique (30a) s'étendant entre les extrémités opposées (70a, 70b) du renfort (16) et présentant des entailles (43a, 43b, 43c) à chaque extrémité. Ces entailles (43a, 43b, 43c) dépassent au moins un tiers de l'épaisseur de la bande (30a). Une deuxième bande similaire (30a) peut également être placée sur le renfort (16).
