Disclosed herein are systems and methods for graft delivery with accurate dispensing. For example, a device for delivering graft material to a target site includes an actuation mechanism and a tube. The tube defines a lumen and an open end and is configured to receive graft material through the open end. The tube includes a pressure relief opening and a dosage window. The pressure relief opening is disposed in a wall of the tube, defining a pressure chamber between the open end and the pressure relief opening. The device further includes a plunger positioned within the lumen of the tube and coupled to the actuation mechanism such that at least a portion of the plunger (or the actuation mechanism) is visible through the dosage window. The actuation mechanism is configured to advance the plunger toward the open end to deliver graft material through the open end.

Methods and systems for performing a preliminary registration is provided. Image data corresponding to an image depicting a tracking device and an anatomical element may be received. Robot positional data corresponding to a position of a robot may also be received. The robot and the anatomical element may be located in a common three-dimensional coordinate system based on the image data and the positional data to yield a preliminary registration. A suggested robot position may be determined based on the preliminary registration and a dimensional reach of a robot arm of the robot.

System and method for preliminary registration

Surgical retractor

A surgical retractor comprises at least one blade including a first arm and a second arm spaced apart from the first arm. The at least one blade further including a member being disposed with the arms to support at least one surgical instrument in a selected orientation relative to a surgical site. Surgical systems, instruments, constructs, implants and methods are disclosed.

Surgical retractor and method

A surgical instrument comprises a first arm including a first closed loop engageable with a first spinal implant disposed with a first vertebral surface. A second arm is movable relative to the first arm and includes a second closed loop engageable with a second spinal implant disposed with a second vertebral surface. Surgical systems, constructs, implants and methods are disclosed.
