Diameter regulator of a device used to extract an element that is inside a cavity and method of use

摘要

A regulator diameter device to extract an element that is inside a cavity, which is introduced together with a flexible sleeve and an applicator, which comprises an adjustment strip of flexible material; and at least of a mean to regulate said diameter, with the adjustment strip open. The means to regulate such strip: a hollow case with a distal end and a proximal end, fixed to one of the traction handles, at least one string passes through this case, in which the distal ends of the at least one string, are fixed to the open ends of the adjustment strip, while the proximal ends of the string are fixed to a pulling system. The method of use of regulator diameter device to extract an element that is inside a cavity comprises the following steps: a. Introduce the combination (regulator device and the applicator) inside the cavity until the applicators' cup makes its first contact with the element to be extracted; b) go on pushing the combination which will open the distal ends of the applicator tentacles; c) once the mayor area of the element to be extracted is passed a first regulation of the adjustment strip is done, pulling the trigger and blocking it in this new position; d) keep on pushing until the final insertion; e) regulate again the adjustment strip until its final measure, being able to measure the diameter of the element to be extracted, which can be read in the pulling system scale; f) inflate the air chamber if the device has one; g) remove the applicator; h) pull the traction handles to extract the element that is inside the cavity.
