Abstract: A medical instrument for percutaneous release procedures, especially on upper or lower limbs, including percutaneous carpal tunnel release or percutaneous A1 pulley release. The medical instrument includes a handle portion to allow handling, orientation and manipulation of the medical instrument by a surgeon, and an elongated rod member secured to the handle portion and extending substantially within a defined plane. A first portion of the elongated rod member extends substantially along a first direction within the defined plane away from the handle portion, and a second portion of the elongated rod member is curved and/or bent within the defined plane. A free end of the elongated rod member, at a terminal end of the second portion, may be shaped as a beveled end including a beveled surface, which beveled end acts as a cutting device to severe tissue, and the beveled surface being inclined with respect to the defined plane.
