HVS and pap smear testing apparatus

A HVS and pap smear testing devise comprising:

• an external cylinder having a proximal end and a threaded distal end;
• a head disposed at the proximal end of the external cylinder, the head being subdivided into a plurality of petal portions;
• a first internal cylinder slidably disposed within the external cylinder;
• a second internal cylinder slidably disposed within the first internal cylinder;
• a recoil cylinder having at least a portion thereof slidably disposed within the second internal cylinder, the recoil cylinder being provided with an aperture at a proximal end thereof;
• a helical screw having a proximal end rotatably mounted at a proximal end of the second internal cylinder and extending into the recoil cylinder via the aperture, wherein the aperture is sized and shaped so as to cause a rotation of the helical screw when the recoil cylinder is moved relative to the helical screw;
• a tip coupled to the proximal end of the helical screw via an aperture defined at the proximal end of the second internal cylinder;
• wherein the external cylinder, the first internal cylinder, the second internal cylinder, the recoil cylinder, and the helical screw are mounted coaxially to each other;
• wherein, when the recoil cylinder is caused to move along a direction from the distal end of the external cylinder to the proximal end of the external cylinder, the first internal cylinder moves toward the proximal end of the external cylinder, thereby opening the head into an open-petal shape, the second internal cylinder moves toward the proximal end of the first internal cylinder, and the recoil cylinder moves toward the proximal end of the second internal cylinder, thereby rotating the helical screw and the tip.
