This disclosure includes an expansion driver for adjusting expandable implants, the expansion driver including an input shaft operably connected to at least one bevel gear, the at least one bevel gear configured to engage each of a first gear and a second gear; the first gear connected to a first output shaft, the first output shaft terminating in a first driver configured to communicate with a first actuator of an expandable implant; the second gear connected to a second output shaft, the second output shaft annularly disposed around at least a portion of the first output shaft; and at least one pinion configured to transfer a torque from the second output shaft to a second driver extending parallel to the first driver and configured to communicate with a second actuator of the expandable implant. Upon a rotation of the input shaft, a torque is applied to at least one of the first driver and the second driver.

Expansion driver

An expandable implant includes: a first endplate, a second endplate, a first translating member moveably coupled to a first actuator, and a second translating member moveably coupled to a second actuator. The first translating member may be configured to move independently from the second translating member, and the first translating member and the second translating member may be configured to change a spatial relationship between the first endplate and the second endplate. The change in spatial relationship may change a resulting height, length, width, angle of lordosis, or other dimension of the expandable implant.

Expandable implants

Assemblies, systems, and methods are directed at a neuromonitoring bone drill bit. The assembly may include a surgical bone drill bit, a neuromonitoring connection in electrical communication with the drill bit, and a shield extending over a distal end of the drill bit. The shield may be configured to withdraw proximally as the drill bit is advanced into a subject's bone. The assembly may be connected to a surgical drill and used in a surgical spinal procedure. In operation, the assembly may be advanced to a subject's bone at a surgical site and the drill bit may rotate into the subject's bone. In response, the shield may engage the bone and the drill bit may be advanced with respect to the shield. The shield may electrically insulate tissue from electrical current passing through the drill bit as it is inserted at the surgical site.

Implants and instruments for providing an ideal trajectory for the insertion of instruments and screws during implantation of an interbody implant in a spinal surgery are disclosed.

Interfixated vertebral body replacement and insertion methods

This disclosure includes an expansion driver for adjusting expandable implants, the expansion driver including: a first driver having a first gear disposed at a first end thereof; and a second driver having a second gear disposed at a first end of the second driver; and a handle operably connected to the first driver and the second driver, the handle having at least one bevel gear rotatably attached thereto, the at least one bevel gear engaging each of the first gear and the second gear; wherein upon a rotation of the handle a torque is applied to at least one of the first driver or the second driver.

Expandable implant expansion driver

Systems, assemblies, devices, and methods for positioning surgical devices at surgical sites are disclosed. An adjustment assembly may include a first connector configured to connect to a surgical articulating arm and a second connector configured to connect to a tool, such as a surgical access tube. A joint assembly may be coupled to the first connector and an elongated assembly may be coupled to the joint assembly and the second connector. An actuator may be coupled to the joint assembly and may be adjusted to secure the elongated assembly in a desired position. One or more clips may be utilized with a surgical access tube to secure a surgical tool within a surgical access tube. The clip may have a single port or more than one port.

Surgical systems

A surgical fixation system including a base plate, a plurality of anchors and a locking element. The base plate has at least a pair of fixation apertures configured to receive at least a portion of the anchors therethrough. The fixation apertures are located within the base plate such that upon proper placement of the base plate within a surgical target site, one of the fixation apertures is positioned over a first bone segment (e.g., a first vertebral body), and the other fixation aperture is positioned over a second bone segment (e.g., a second vertebral body).
