A system for dilating tissue includes a retractor having a pair of retractor blades that are movable towards and away from each other to retract tissue of a patient. The retractor blades have longitudinal guide channels. A first pin is attachable to a first vertebra. The system also includes an interbody spacer insertion device that has a guide channel for slidably engaging the longitudinal channel guide and is releasably attachable to an interbody spacer. The interbody spacer insertion device is configured to guide the interbody spacer into a space between adjacent vertebrae. A method for using the system includes advancing the retractor blades towards first and second vertebrae. The first retractor blade is attached to the first vertebra using the first pin and the retractor blades are moved away from each other. The interbody spacer insertion device is translated towards the vertebrae to position the interbody spacer between the vertebrae.

A surgical retractor tool includes a handle and a blade extending transversely from a front end of the handle. The blade includes a proximal portion and a distal portion with respective proximal and distal tissue engaging surfaces. The distal tissue engaging surface may be skewed relative to the proximal tissue engaging surface such that the handle may be angled relative to a direction of retraction when the surgical retractor tool is used. A distal tip of the retractor may include a curved tongue that may be curved in a direction opposite the direction of retraction.

A lumbar interbody fusion device includes a first wing, a second wing, and a bridge. The bridge has an arcuate resting shape and include a first end connected to the first wing, a second end connected to the second wing, and at least one aperture extending through the bridge in a radial direction relative to the arcuate resting shape of the bridge. The bridge is elastically deformable such that a distance between the first wing and the second wing may vary according to elastic deformation of the bridge.

In some embodiments, the present disclosure relates to a system that includes an insertion tool and a drill guide. The insertion tool includes a body with a distal portion and a distal end. The body has a first engagement feature extending longitudinally along the distal portion and two arms extending longitudinally from the distal end of the body. The drill guide includes two bores and an open faced channel therebetween. The open faced channel includes a second engagement feature slidably engageable with the first engagement feature on the body of the insertion tool. The two bores are adapted for the disposal of a fastener driver tool therethrough.

A surgical instrument to implant spinal implants including a shaft, a sleeve, and a handle assembly. The shaft defining a longitudinal axis and having a slotted portion with first slots and second slots. The sleeve rotatably disposed around the slotted portion. The handle assembly pivotably attached to the sleeve by a pivot pin, the handle assembly having a positioning tip sized to be received in the first and second slots of the slotted portion. The handle assembly can pivot about the pivot pin between a first position and a second position. In the first position, the positioning tip engages one of the first slots, while in the second position, the positioning tip engages one of the second slots.

A tool for creating an incision at a surgical site includes a body for use with a robotic end effector having a proximal end and a distal end, and a blade positioned at the distal end of the body, the blade having a proximal end and a distal end, the blade having a cutting edge defining a first portion extending outwardly from or adjacent to the proximal end to a maximum width and a second portion extending inwardly from the maximum width to a sharp distal tip.

A spinal fixation device includes an outer housing and an end plate assembly coupled with the outer housing. The outer housing defines an aperture and a longitudinal axis. At least a portion of the end plate assembly is slidably received within the outer housing. The end plate assembly includes a first end plate configured to engage a vertebral body, wherein the end plate assembly is selectively movable between a first position in which the first end plate is spaced apart from the outer housing and a second position in which the first end plate is adjacent the outer housing. Further, the first end plate is selectively adjustable to an angular orientation of a plurality of angular orientations with respect to the longitudinal axis of the outer housing.

Systems, devices, and associated methods for correcting spinal column deformities that help minimize a number of attachment anchors utilized for correction, facilitate use of straight or contoured rods, and/or help promote a more natural, physiologic motion of the spinal column.

A fixation device includes a head, a tapered body coupled to the head and extending along a central longitudinal axis, and a flexible tail extending distally from the tapered body and defining a central bore therethrough. The flexible tail is movable from an initial configuration aligned with the central longitudinal axis to a deflected configuration that extends away from the central longitudinal axis when a force is applied to the flexible tail.

In one embodiment, the present disclosure relates to a system that includes a plate holder and an awl. The plate holder has a first end and a second end with an engagement feature at the second end that is engageable with a bone plate. The awl is releasably engaged to the plate holder and includes a locking mechanism adjustable from a first setting to a second setting and a tip. When the locking mechanism is in the first setting, the awl is fixed relative to the plate holder and the tip is disposed within the plate holder. When the locking mechanism is in the second setting, the awl is axially translatable relative to the plate holder such that the tip of the awl extends out of the second end of the plate holder.
