Patent ID: 8608765

Claim:
A device for minimally invasive tendon sheath release, comprising: a handle having a cavity contained therein; a sheath having a proximal and a distal end wherein the proximal end projects from the cavity and the distal end of the sheath has a top and a bottom portion; a guide probe having a spherical tip attached to the bottom portion of the distal end of the sheath; a dorsal outrigger guide having a spherical tip attached at the top portion of the distal end of the sheath; a cutting blade disposed between the guide probe and the dorsal outrigger guide; a hemi-cannula disposed on the distal end of the sheath further comprising a tubular structure having a proximal end, a distal end, a top portion and a bottom portion wherein distance between the proximal end and the distal end define a longitudinal distance of the tubular structure; a rounded opening disposed in the proximal end adapted to receive a device for minimally invasive tendon sheath release; and a sliding means disposed at the proximal end of the top portion; wherein the top portion of the distal end is downwardly tapered; wherein the bottom portion extends distally from the opening for less than half of the longitudinal distance of the tubular structure, wherein the hemi-cannula may be moved proximally to expose the guide probe or distally to contain the guide probe.
