Devices, systems, and methods for transvaginal, ultrasound guided hysteroscopic surgical procedures

A hysteroscopic surgical system, comprising:

• a hysteroscope including a handle and a shaft extending distally from the handle;
• and
• an ultrasound device, including:
• a collar defining a longitudinal lumen configured to receive the shaft for slidably positioning the collar about the shaft;
• a body depending from the collar and protruding distally relative to the collar;
• an ultrasound sensor assembly disposed within the body, the ultrasound sensor assembly configured for ultrasound imaging, wherein the collar and the body are configured for positioning within a vaginal canal of a human patient for positioning the longitudinal lumen of the collar in substantial alignment with a cervix of the human patient to enable the shaft to extend through the cervix and into a uterus of the human patient;
• and
• a drive assembly disposed within at least one of the collar or the body, the drive assembly configured to receive an actuation input and to drive movement of the body relative to the collar in response to receipt of the actuation input.
