Abstract: A micro retractor for tissue retraction during surgery has a head with an opening extending from an upper surface of the head to a lower surface of the head with a first leg fixed to a first side of the head opening and extending downward relative to the lower surface, and a second leg fixed to a member movable in the head opening and extending downward relative to the lower surface, together defining a channel allowing various medical instruments to be inserted therein during retraction. A distal first leg end and a distal second leg end meet, forming a pivot point wherein the dimension of the channel remains nearly fixed and tissue retraction at the pivot point remains constant, while the proximal second leg end is movable via the member to vary the dimension of the channel opening which also varies the dimension of the channel opening and the channel.

Abstract: A method for decorticating a vertebral endplate material from spinal vertebrae using a decorticating tool having height adjustable blades at a distal end of a shaft assembly, translates axial movement of a control rod of a shaft assembly of the vertebral endplate preparation tool with height adjustable blades into radial blade height change (extension and retraction) through a controller of a handle assembly. The blades may also be configured for collecting and removing shaven vertebral endplate material. The blades controllably move outward radially from the distal end of the shaft assembly and controllably move inward radially into the distal end of the shaft assembly upon manipulation of the controller. Radial blade extension and retraction from the distal end is accomplished via mutual angled dovetail features of the blades and the distal end, or via pins of the distal end of the shaft assembly situated in angled slots of the blades.

Abstract: A vertebral endplate preparation (decorticating) tool has height adjustable blades at a distal end of a shaft assembly for decorticating/shaving vertebral endplate material from spinal vertebrae, translates axial movement of a control rod o the shaft assembly of the vertebral endplate preparation tool with height adjustable blades into radial blade height change (extension and retraction) through a controller of a handle assembly.

The blades controllably move outward radially from the distal end of the shaft assembly and controllably move inward radially into the distal end of the shaft assembly upon manipulation of the controller. Radial blade extension and retraction from the distal end may be accomplished via mutual angled dovetail features of the blades and the distal end, or via pins of the distal end of the shaft assembly situated in angled slots of the blades.

Abstract: A medical instrument for collecting spinal disc material from outside a perimeter of a tube has a handle, a shaft assembly defining a proximal end extending from the handle, a distal end, and a longitudinal axis, and an articulated scoop assembly at the distal end of the shaft assembly that provides for swiveling movement of a scoop of the scoop assembly relative to the longitudinal axis of the shaft assembly to provide movement of the scoop beyond the perimeter of the tube.

The handle is formed by a handgrip portion configured to receive a palm of a user and a lever portion with a loop configured to receive one or more fingers of the user. The handle is biased so the scoop is normally coaxial with the shaft assembly.

Abstract: Systems and methods for detecting regions of interests (ROIs) in biomedical images are described herein. A computing system may identify a biomedical image having an ROI. The computer system may apply an object detection model to the biomedical image. The object detection model may generate a feature map using the biomedical image. The object detection model may generate an anchor box corresponding to a portion of the pixels in the feature map. The computing system may apply an instance segmentation model to identify a segment of the biomedical image within the anchor box corresponding to the ROI. The computer system may provide an output based on the segment to identify the ROI in the biomedical image.
