A handheld microscope for direct, optical viewing of surgical sites. The system includes an illumination system, as well as viewing optics contained in a housing, the housing being configured for coupling to a proximal end of an access port. In some embodiments, the access port houses a light probe coupled to a source of the illumination system for irradiation of the surgical area. The system may include aspiration capability for clearing debris from the surgical site.

Handheld microscope for cannulated surgical systems

A spinal implant system includes an inserter that passes through a spinal implant for attachment to a distal end of the spinal implant. By this arrangement, stability of the implant system is enhanced for placement of the spinal implant while reducing local stresses imparted at the attachment. The disclosed spinal implant system may include an access tube that is coupled to a proximal end of the spinal implant. After placement of the spinal implant, the inserter may be removed from the spinal implant and access tube, providing access via the access tube to an interior of the spinal implant and the corresponding space between the vertebral endplates.

Spinal fusion implant system and method

An anchoring system for a spinal support rod. The anchoring system includes a self-tapping orthopedic fastener that is bored through the ilium via a lateral incision and a mounting receiver that is positioned to receive the orthopedic fastener via a posterior incision. The orthopedic fastener may be implanted from a lateral approach or a posterolateral approach. The mounting receiver may be implanted from a posterior or superior posterior approach.

Iliac anchor system

A cannulated plunger assembly for setting a tether with anchors on both ends to extend between adjacent vertebrae. The cannulated form enables minimally invasive access to an evacuated space between the vertebral endplates. Each of the anchors are coupled to a respective one of a pair of plunger arms, the plunger arms being configured to deploy the anchors beyond an outer radius of a tubular housing. In some embodiments, in a retracted configuration, the pair of plunger arms are surrounded by the housing, and in a deployed configuration, the pair of plunger arms extend through an open distal end of and beyond an outer radius of the housing to drive the anchors into the vertebral end plates.
