A system and method for applying energy, particularly high-frequency (HF) energy, such as radiofrequency (RF) electrical energy, to a living body can include a cannula hub.

Electrosurgical system

Electrosurgical generator

A spinal implant provides supplemental and dynamic fixation and/or stabilization of the spine via connection to one or more existing or new spinal fixation and/or stabilization spinal constructs. The supplementary spinal fixation/stabilization implant has a first attachment device configured to couple to an existing or new spinal fixation/stabilization construct and a second attachment device configured to couple to the existing or new spinal fixation/stabilization construct at a second location. The first and second attachment devices are joined to each other via a resilient connector that allows dynamic movement between the first and second attachment devices.

Spinal rod connector

A spinal rod guide and/or guide assembly is provided for mounting a spinal rod onto a spinal rod holder/connector of a vertebral bone screw. The spinal rod guide is configured to extend between an opening in a patient's body and the spinal rod holder of the vertebral bone screw assembly, to receive a spinal rod therein, and thereafter accurately guide the spinal rod into the spinal rod holder. The spinal rod guide is defined by a first elongated arc portion and a second elongated arc portion to define a guide tube for the introduction and placement of additional spinal rod components onto the spinal rod connector, particularly, but not necessarily, for securing the spinal rod into the spinal rod connector. The elongated arc portions are mountable or initially attached onto a top of a spinal rod holder of a spinal rod bone screw assembly. The elongated arc portions (tube) define first and second longitudinal slots extending from a top of the elongated arc portions to a bottom of the elongated arc portions. The two longitudinal slots are situated such as to be diametrically opposite one another. Each longitudinal slot aligns with a spinal rod slot of the spinal rod holder to thereby allow easy placement of the spinal rod into the spinal rod holder. Thereafter, the defined elongated tube provides direct communication and alignment with the top of the spinal rod holder in order to receive a spinal rod connector drive screw for securing the spinal rod into the spinal rod holder.

Spinal rod guide for a vertebral screw spinal rod connector assembly

A guide assembly includes a spinal screw assembly having a bone screw and a spinal rod holder; and a spinal rod guide having first and second elongated arc portions defining a pair of longitudinal slots extending along the first and second arc portions, each of the first and second arc portions further defining at least one recess extending transversely from each of the longitudinal slots, the at least one recess configured to receive at least a portion of a reduction tool to enable reduction of a spinal rod received within the spinal rod holder.
