Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.

A bone drill guiding device including a drill entry part comprising a cannula having a distal end portion and sized to receive a bone drill, a drill exit part comprising a fixation tip portion and a coupling that rigidly couples the drill entry part and the drill exit part so that longitudinal axes of the cannula distal portion and the fixation tip portion are arranged on a single mutual axis. In some embodiments, the coupling is a linear sliding coupling that parallels the single mutual axis.

Guide tools for installation of fixation devices. At least one example embodiment includes: a delivery tube, the delivery tube defines a slot that runs from the distal end to the proximal end; a guide tube coupled to the delivery tube; and a handle coupled to the proximal end of the delivery tube and coupled to the proximal end of the guide tube. The handle may include a first channel into an interior of the delivery tube through the slot, and a receptacle in operational relationship to the delivery tube and the first channel.

Various exemplary methods, systems, and devices for instability repair are provided. In general, a surgical device can be configured to drill a hole in bone and to deliver a suture anchor into the hole. In this way, a single surgical device can drill the hole and deliver the anchor into the hole for securing soft tissue to the bone. The anchor can be configured to allow the soft tissue to be secured to the bone using a suture coupled to a suture anchor without the need to knot or otherwise tie the suture to secure the soft tissue in place relative to the bone.

Devices, systems, and methods are provided for ligament repair procedures, and can be used to establish a location and trajectory for forming a bone tunnel in bone. One exemplary embodiment of a surgical guide for using in a ligament repair procedure includes a guide arm and a carriage that can be selectively locked along the guide arm to define an angle of the bone tunnel. The guide arm also defines a location of a distal end of the bone tunnel. In some embodiments the carriage is configured to have a bullet side-loaded into it, and the bullet can be used to define a location of a proximal end of the bone tunnel. The present disclosure also provides for a gage that limits the distance a drill pin that drills the bone tunnel can travel. A variety of other, devices, systems, and methods are also provided.

A fixation device. At least one example embodiment is a bone anchor comprising: a proximal head; a bollard coupled to the proximal head; a first barb coupled to the bollard, the first barb extends outward a first distance measured perpendicularly from an anchor central axis, the first distance greater than half the transverse dimension of the bollard, and the first barb extends outward at a first radial from the anchor central axis; and a second barb coupled to the first barb, the second barb extends outward a second distance measured perpendicularly from the anchor central axis, the second distance greater than half the transverse dimension of the bollard, and the second barb extends outward at a second radial from the anchor central axis, the second radial at a second rotational orientation at least 36 angular degrees from the first radial.

Apparatus for locating an attachment position for a reconstructed anterior cruciate ligament on an attachment surface of a bone comprises locating means 51, 61 arranged to locate at least one reference surface 4 of the bone and guide means 53, 54 arranged to define the attachment position in two dimensions on the attachment surface relative to the reference surface.

An apparatus for indicating the position and length of a bone tunnel, including a first member configured to couple with a drill guide; and a second member in spaced relation to the first member, the second member comprising an indicator configured to provide an indication of thickness of a boney member with the first member disposed on a first side of the boney member and the second member disposed on a second side of the boney member.

The present invention provides a drill guide for orthopedic surgery. The drill guide is configured to facilitate drilling of a bone tunnel with a correct and repeatable placement. The drill guide is designed for drilling of the femoral bone during knee surgery. More particularly, in certain embodiments the drill guide is designed for ACL repair and replacement surgery. In a preferred embodiment of the present invention, the guide has 5 members: a center rail, a side rail, an anteromedial slider, a femoral slider, and a center pin.
