CLAIMS

1. A universal surgical device capable of locating a neurosurgical site, comprising

a tubular member (110), defining a passageway, having a distal end (101) and a proximal end (102);

an elongated navigation probe (200), which is longer than the tubular member (110) and having a tapering tip (203), configured to collectively slide into the passageway until the tip protrudes from the distal end (101) of the tubular member, that the tubular member (110) and the engaged probe (200) concurrently move to the neurosurgical site under guidance of a navigation system in communication with the tubular member (110), wherein the probe (200) moves out from the passageway and the tubular member (110) is retained at the distal end (101) substantially contacting the neurosurgical site. 2. A universal surgical device according to claim 1 further comprising a handle (104) mounted at the proximal end (102) of the tubular member (110).

3. A universal surgical device according to claim 2, wherein the handle (104) is formed into a substantially E-shape, T-shape, volar-shape or cross-shape.

4. A universal surgical device according to claim 1, wherein the proximal end (102) is having a slot (108) longitudinal to the tubular member (110).

A universal surgical device according to claim 4, wherein the probe (200) comprises a protruding structure (201) engages to the slot (108) to secure the probe (200) to the tubular member (110).

A universal surgical device according to claim 1 , wherein the tubular member (110) is having a distal segment (105) and a proximal segment (106) which are detachably connected in a tip-to-tip fashion substantially defining the 18

passageway.

7. A universal surgical device according to claim 6, wherein the distal segment (105) and the proximal segment (106) are detachably comiected using male and female locking system.

8. A universal surgical device according to claim 7, wherein the male locking system comprises a protruding marking.

9. A universal surgical device according to claim 7, wherein the female locking system comprises an L-shaped groove (107) longitudinal to the proximal segment (106).

10. A universal surgical device according to claim 1, wherein the tubular member (110) is straight or bayonet in shape.

11. A universal surgical device according to claim 1 or 2, wherein the navigation system comprises a plurality of navigation reference units (103) mounted on the handle (104) and/or the tubular member (110).

12. A universal surgical device according to claim 1, wherein the navigation system corresponds to medical images of the neurosurgical site.

13. A universal surgical device capable of locating a neurosurgical site, comprising a tubular member (110) having a proximal end (101) and a distal end (102) configured to receive a probe (200) until the tip (203) of the probe protrudes from the distal end (102) of the tubular member,

wherein the tubular member is having a proximal segment (105) and a distal segment (106) which are detachably connected in a tip-to-tip fashion substantially defining a passageway to receive a probe therethrough, 19

wherein the tubular member (110) moves to the neurosurgical site under guidance of the probe (200) and continues to locate the neurosurgical site upon removal of the probe (200).
