Stereotactic device for use in medical procedures

A stereotactic device (100, 200) for use in a medical procedure, the stereotactic device (100, 200) comprising:

• a clamp (102, 202) configured for mounting the stereotactic device (100, 200) on to a rigid part (104) of an operating table;
• a bar (106, 206) comprising a first end (108A, 208A) and a second end (108B, 208B), the first end (108A, 208A) configured for being held by the clamp (102, 202), and the second end (108B, 208B) is located in a y-z plane (116, 216) substantially at a centre of the operating table in the x direction;
• an articulating arm assembly (120, 220) comprising:
• a bottom arm (122, 222) having a first end (124A, 224A) and a second end (124B, 224B), the first end (124A, 224A) being coupled to the second end (108B, 208B) of the bar (106, 206) through a first flexible joint (130, 230);
• a top arm (126, 226) having a first end (128A, 228A) and a second end (128B, 228B), the first end (128A, 228A) coupled to the second end (124B, 224B) of the bottom arm (122, 224) through a second flexible joint (140, 240), for being rotatable in the y-z plane (116, 216);
• a sleeve (150, 250) mounted to the second end (128B, 228B) of the top arm (126, 226) with a third flexible joint (145, 245) and configured for holding the medical device (154);
• wherein the first flexible joint (130, 230), the second flexible joint (140, 240) and the third flexible joint (145, 245) provide three degrees of freedom for moving and positioning the tip (156) of the medical device (154).
