Abstract A cervix-to-rectum measuring device to be used in the treatment of cervical cancer which includes a handle and a probe pivotably connected to the handle for insertion in the rectum. The measuring device further includes means for coupling the handle to an intrauterine radiation applicator when the latter is positioned in the uterine cervix and the probe is inserted in the rectum to pivot the handle about the probe. A gear is provided which is adapted to pivot with the probe. A pinion pivotably connected to the handle meshes with the gear. A pointer fixed to the pinion is displaced in response to the pivoting of the handle about the probe, and this displacement can be read from a scale on the handle, providing an indication of the cervix-to-rectum distance.
A device for use with a radiation applicator comprising: a handle, a single probe pivotably connected to said handle and insertable in a rectum, means on said handle for coupling said handle to the applicator, and means on said handle responsive to the displacement of said probe when inserted into a rectum relative to the applicator when inserted into an uterine cervix for indicating the distance between said cervix and rectum.
