Device for radiation therapy of rectal cancer

A device for pushing a scar in a perineal region of a patient whose rectum and anus have previously been surgical removed, so that the scar can be optimally positioned during radiation treatment of a rectal area of the patient, said device comprising

• a base that is positioned beneath a patient's legs as the patient lies supine or prone on a radiation therapy support platform;
• a guide and support member extending upwardly from said base so that said guide and support member positioned between thighs of the patient;
• a slide member supported by said guide and support member, said slide member being constrained to slide back and forth along the guide and support member in a direction substantially parallel to the patient's legs so that pressure exerted on the patient's perineum by a leading end of the slide member can be adjusted;
• means for manually moving the slide member in its movement relative to said guide and support member;
• and
• means for retaining said slide member in any selected position along the movement of said slide member relative to said guide and support member,
• whereby the slide member can be manually moved toward the patient's perineum so that the leading end of the slide member pushes the perineal scar cephalad, and then holds the scar in proper position during subsequent radiation therapy of the rectal area of the patient.
