In one embodiment, a system for image-guided drainage of abscesses includes a trocar configured to guide a tubular drain toward an abscess within the body of a patient. The trocar includes a joint portion pivotably coupling a proximal portion and a distal portion. The joint portion includes a locking mechanism that when engaged locks the proximal portion in place relative to the distal portion. The joint portion enables the trocar to pivot between an advancement position for advancing the trocar into the body of the patient and an image position for performing a radiology image of a partial advancement of the distal portion within the body of the patient. The image position reduces, relative to the advancement position, the angle between respective central axes of the proximal and distal portions.
