Abstract:
1. A surgical instrument for securing a spinal fixation rod with a first and a second spinal fixation device, the surgical instrument comprising: a driver configured to apply torque to a locking cap of the first spinal fixation device, so as to lock the locking cap against the spinal fixation rod, the driver defining a longitudinal axis, a proximal end, and a distal end opposite the proximal end along the longitudinal axis, such that the driver is elongate along the longitudinal axis, the driver also comprising a driver shaft located between the proximal end and the distal end; the driver shaft located within and extending through a tubular sleeve such that: (i) the shaft of the driver is rotatable with respect to the sleeve about the longitudinal axis and (ii) the sleeve is prevented from translating along the longitudinal axis of the driver; and an actuator comprising (1) a distal end that is configured to fit over the spinal fixation rod, (2) a proximal end opposite the distal end, (3) a proximal body portion located distally of the proximal end, (4) a distal body portion located proximally of the distal end, and (5) an intermediate body portion located between the proximal body portion and the distal body portion, wherein the intermediate body portion defines a recess sized to receive the shaft of the driver such that the shaft of the driver extends through the recess; wherein the distal end, proximal end, proximal body portion, distal body portion, and intermediate body portion of the actuator are integrally formed together, and wherein the actuator pivots, translates, and rotates about shaft of the driver.
