ORTHOPEDIC PIN FOR OPTICALLY ANALYZING A BONE REGION
An orthopedic pin (100) for optically analyzing a bone region (110) includes an elongate shaft (101) and at least one optical fiber (105). The elongate shaft has a circular outer cross section with a first diameter (D1), a distal end (102) for insertion into bone, a proximal end (103), and an optica...

description | An orthopedic pin (100) for optically analyzing a bone region (110) includes an elongate shaft (101) and at least one optical fiber (105). The elongate shaft has a circular outer cross section with a first diameter (D1), a distal end (102) for insertion into bone, a proximal end (103), and an optical connector portion (104) disposed towards the proximal end (103). The at least one optical fiber (105) extends within the elongate shaft (101) between the optical connector portion (104), and the distal end (102) for transmitting optical radiation between the optical connector portion (104) and the bone region (110) when the distal end (102) is inserted into the bone region (110). The optical connector portion (104) comprises a reduced-diameter portion (106). The reduced-diameter portion (106) extends along at least a portion of the elongate shaft (101), and has an outer cross section comprising a width (Drd) perpendicularly with respect to the elongate shaft (101). The width (Drd) is less than the first diameter (D1). |
