Device for reproducable alignment of bodily tissue for programme of external radiotherapy treatment

Positioning tool (200) for assisting treatment of a subject in an external radiotherapy programme comprising two or more external radiotherapy treatment sessions comprising:

• a steering guide (300) having a proximal (40) and distal (20) end comprising:
• a rigid effector shaft (310) at the distal end (20) configured for insertion into a canal (602) of the subject (50), or for attachment to an inserter (204) configured for insertion into a canal (602) of the subject (50), and
• a rigid handle portion (316) disposed at the proximal end (40) in fixed relation to the effector shaft (310) for controlling the position and/or direction of the effector shaft (310), and being configured to couple to an end effector fitting (430) of a robotic arm (400),
• wherein:
• the positioning tool (200) is configured to move and/or fix the canal (602) and the bodily tissue (610) for the external radiotherapy treatment session, and
• the handle portion (316) is provided with a docking beacon (340) configured to provide information as to the position and optionally orientation of the steering guide (300) relative to an end effector fitting (430) of a robotic arm (400).

Positioning tool (200) for assisting treatment of a subject in an external radiotherapy programme comprising two or more external radiotherapy treatment sessions comprising:

• a steering guide (300) having a proximal (40) and distal (20) end comprising:
• a rigid effector shaft (310) disposed at the distal end (20) configured for:
• insertion through an entrance to a canal (602) in connection with bodily tissue (610) of the subject, or
• repeatable removable insertion into an elongated member lumen (214) of an elongated member (210) of an inserter (204) having a proximal (40) and distal (20) end which elongated member (210) is configured for insertion through an entrance to a canal (602) in connection with bodily tissue (610) of the subject,
• and
• a rigid handle portion (316) disposed at the proximal end (40) in fixed relation to the effector shaft (310) for controlling the position and/or direction of the effector shaft (310),
• wherein
• the positioning tool (200) is configured to move and/or fix the canal (602) and the bodily tissue (610) for the external radiotherapy treatment session, and
• the steering guide (300) is provided with an image capture system (360) configured for capture of images from a distal tip (361) of the effector shaft (310) allowing the effector shaft (310) to be inserted into the entrance to the canal (602) or into the elongated member lumen (214) under guidance of the captured images.
