Claim:
A device for surgical operations on a prolapse, comprising: a hollow stretcher body having a prevalent development direction along a longitudinal axis and being insertable in an orifice, the stretcher body having a closed front portion and exhibiting a lateral through-window, defining an area of intervention and adapted to realize a communication between an internal cavity of the stretcher body and a portion of a prolapse, a mobile wall defining the through-window in combination with the stretcher body and being slidably associated to the stretcher body in order to open and close the through-window between a configuration of minimum extension and a configuration of maximum extension of the through-window, wherein the mobile wall is movable according to a plurality of intermediate positions corresponding to intermediate configurations of the through window between the minimum and the maximum extensions of the through window; wherein the through window develops along the longitudinal axis of the stretcher body and the mobile wall is movable along the longitudinal axis of the stretcher body in such a way as to vary the extension of the through window in a direction parallel to the longitudinal axis of the stretcher body; wherein the device comprises means for blocking which acts between the mobile wall and the stretcher body in order to maintain the through-window stably in the configuration of minimum extension during insertion of the stretcher body, wherein the blocking means comprises at least one appendage which is elastically associated to the mobile wall and which is insertable and extractable by a snap-fit in a corresponding seating afforded in the stretcher body; wherein the device comprises two guides afforded in the stretcher body and two skates connected to respective opposite sides of the mobile wall and slidable in the guide; the at least one appendage comprising two appendages, each associated to a respective skate, and wherein the device further comprises two seatings, each of which is occupiable by a respective appendage; and wherein each skate comprises a fixed portion which is rigidly connected to the mobile wall and a projecting portion which projects from the fixed portion towards a front end of the stretcher body; each appendage being arranged on the projecting portion.
