SYSTEMS AND METHODS FOR MEASURING CERVICAL DILATION

摘要

Systems and methods for measuring cervical dilation are provided that include two biocompatible fasteners affixed to opposing cervical or vaginal walls, and a biocompatible string coupled to the fasteners, yet free to slide between the fasteners. The string has ends extending outside the vaginal opening of the patient, so that changes in cervical dilation can be measured by monitoring the relative movements of the string ends The heads of the screws are preferably concave, with a loop attached thereon, so that the string can be coupled to the screws by running the string therethrough Further, the tips of the screws are preferably blunt, to minimize loss of blood and the possible risk of HIV infections.
