Abstract
The present invention is a biopsy guide for use with a medical ultrasound scanhead of the type used for intravaginal scans and ultrasound guided biopsies. The guide fits over an intravaginal scanhead, and it includes a slot for guiding a biopsy needle. The guide also includes a unique needle cover which is slidably attached to the guide and which encloses a biopsy needle until actual flesh penetration is desired, thereby preventing unnecessary injury to a patient in the course of the examination.
