Apparatus and method to permit selective cutting and coagulation required in fine and delicate surgical procedures. The apparatus includes two body members having proximal ends and distal ends with jaw members located adjacent the body member's distal ends. The body members are joined at a pivot located adjacent to the first and second jaw members joining the first and second body members where the body members' rotation about the pivot defines a plane of rotation. The scissors are adapted for selective application of energy to at least one jaw member by a switch located in the plane of rotation.

Methods and devices are disclosed for inhibiting proximal junctional failure in a patient having posterior spinal instrumentation. One or more tension bands can be threaded through transverse bores in a spinous process of a vertebral body of a spine, superior and adjacent an uppermost instrumented vertebral body. Tension is applied to bias the spinous processes together and also in an inferior direction. The tension band is locked with respect to the spine, to maintain tension.

Some implementations of the disclosure are directed to single portal surgical systems. In one implementation, an apparatus includes first, second, and third cannulas. Fluid flows through a proximal opening of the first cannula. The second cannula couples within the first cannula such that an outer wall of the second cannula contacts an inner wall of the first cannula. The second cannula includes a first distal opening and a first slot longitudinally extending along the second cannula. Fluid entering the proximal opening flows through the first slot and exits at a distal end of the. The third cannula couples within the second cannula such that an outer wall of the third cannula is in touching relation with an inner wall of the second cannula. The third cannula includes a second distal opening that rotationally interacts with the first distal opening during tissue debridement.

A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.
