A laminectomy forceps comprising: a handle joined to a fixed beak having a sliding tray defining a cutting end; an actuation lever in opposite position of the handle for actuating the sliding tray; wherein the fixed beak is provided with a cutting backing end corresponding to the cutting end of the tray in order to generate a cutting area; a force multiplier lever mechanism (8, 9, 10); and wherein the actuation lever is adapted to articulate with respect to the tray and is connected thereto by the force multiplier lever mechanism such that the actuation lever determines sliding of said tray; characterised in the force multiplier lever mechanism (8, 9, 10) comprising: a first L-shaped arm hinged to the handle and arranged to be actuated by said lever; a second arm connected to and configured to articulate with respect to the first L-shaped arm; a third L-shaped arm connected to and configured to articulate to the second arm, the third L-shaped arm being hinged to the handle and arranged to actuate the tray; wherein the first L-shaped arm defines a longer portion configured to interact with the actuation lever and a shorter portion connected to said second arm; wherein the third L-shaped arm defines a shorter portion connected to the second arm and a longer portion connected to the tray; and wherein the arms are arranged so that said force multiplier lever mechanism multiply the force exerted by a surgeon on the actuation lever and transmit the multiplied force to the tray. a handle joined to a fixed beak having a sliding tray defining a cutting end; an actuation lever in opposite position of the handle for actuating the sliding tray; wherein the fixed beak is provided with a cutting backing end corresponding to the cutting end of the tray in order to generate a cutting area; a force multiplier lever mechanism (8, 9, 10); and wherein the actuation lever is adapted to articulate with respect to the tray and is connected thereto by the force multiplier lever mechanism such that the actuation lever determines sliding of said tray; characterised in the force multiplier lever mechanism (8, 9, 10) comprising: a first L-shaped arm hinged to the handle and arranged to be actuated by said lever; a second arm connected to and configured to articulate with respect to the first L-shaped arm; a third L-shaped arm connected to and configured to articulate to the second arm, the third L-shaped arm being hinged to the handle and arranged to actuate the tray; wherein the first L-shaped arm defines a longer portion configured to interact with the actuation lever and a shorter portion connected to said second arm; wherein the third L-shaped arm defines a shorter portion connected to the second arm and a longer portion connected to the tray; and wherein the arms are arranged so that said force multiplier lever mechanism multiply the force exerted by a surgeon on the actuation lever and transmit the multiplied force to the tray. a first L-shaped arm hinged to the handle and arranged to be actuated by said lever; a second arm connected to and configured to articulate with respect to the first L-shaped arm; a third L-shaped arm connected to and configured to articulate to the second arm, the third L-shaped arm being hinged to the handle and arranged to actuate the tray; wherein the first L-shaped arm defines a longer portion configured to interact with the actuation lever and a shorter portion connected to said second arm; wherein the third L-shaped arm defines a shorter portion connected to the second arm and a longer portion connected to the tray; and wherein the arms are arranged so that said force multiplier lever mechanism multiply the force exerted by a surgeon on the actuation lever and transmit the multiplied force to the tray.
