A bone repair system, kit and method for percutaneous repair of a bone segment containing a first bone segment and a second bone segment in a patient, each bone segment having a drill hole. The system comprises a longitudinal member configured to contact the first bone segment and the second bone segment and having at least one opening and cleats on the side adapted to contact the first bone segment and the second bone segment; a first fastener assembly configured to be disposed through the opening of the longitudinal member to hold the longitudinal member in place through the opening and the hole in the first bone segment; and a second fastener assembly configured to be disposed through the opening of the longitudinal member to hold the longitudinal member in place through the opening and the hole in the second bone segment.

An osseous anchoring implant with facilitated extraction having: an expandable sleeve extending between a proximal portion, and a distal portion, defining a longitudinal axis, a screw extending between a proximal portion and a distal portion on an axis collinear with the axis, having an external profile complementary to the internal profile of said expandable sleeve, the screw comprising at least one distance marker to visualize the moment when the screwing of the screw in the expandable sleeve must be carried out in the opposite direction to the screwing of the expandable sleeve. The implant switches from a folded rest position to a deployed position by the penetration of the screw in the expandable sleeve. The distal portion including self-tapping notches. The distal portion includes a self-milling head.

A cylindrical shaft may be gripped with an apparatus including a housing having an axis and an inner surface with multiple asymmetric cam surfaces, a proximal end including a means to rotate the housing, and a distal end having an opening configured to receive the cylindrical shaft, at least two cylindrical gripping members configured to grip the cylindrical shaft, where each cylindrical gripping member contacts a corresponding asymmetric cam surface at a first rest position, and a rotatable frame which holds each pair of cylindrical gripping members at a fixed angular orientation relative to each other. The rotatable frame is configured to rotate upon insertion of the cylindrical shaft into a space defined by the gripping members so that each gripping member moves away from the axis of the housing along a first portion of the corresponding asymmetric cam surface. After insertion of the cylindrical shaft, the housing is configured to rotate so as to cause each gripping member to move toward the axis of the housing along the corresponding asymmetric cam surface.

A chuck assembly for a medical device is provided. The chuck assembly includes a mounting base structured to couple to a tool; a housing coupled to the mounting base; and a cam sleeve within the housing and movable with respect to the housing between a locked position and an unlocked position, the cam sleeve having an annular base, an arm extending from the annular base, and a cam extending laterally from the arm.

Systems, instruments, and methods for operating a surgical instrument are disclosed. The instrument may include a drive shaft axially aligned with a central axis of the surgical instrument. The drive shaft may include a first mating end and be rotatably supported within a drive housing having a contoured interior supporting the first mating end. The instrument may include an outer shaft having an outer receiver interface configured to selectively couple and uncouple to a connecting portion of a receiver. The instrument may also include a plunger that is axially aligned with the central axis and having a second mating end disposed within the contoured interior of the drive housing. In various embodiments, the second mating end may be axially aligned with and in contact with the first mating end. In various embodiments, the plunger may be configured to linearly translate along the central axis upon rotation of the drive shaft.

Systems, instruments, and methods for operating a surgical instrument. The methods comprising: receiving at least a portion of an external object in a recess of a hollow shank; rotating a first shaft disposed within the hollow shank; using rotation of the first shaft to cause translational movement of a second shaft of the surgical instrument in a first direction away from the first shaft and along a central axis of the surgical instrument; applying a pushing force on the external object using the second shaft that is experiencing the translational movement; and causing translational movement of the second shaft in a second direction opposed from the first direction after the pushing force has been applied to the external object.

Various implant holding systems are provided herein that include an outer tube, an inner tube, and a holder. The implant holding systems can be designed to hold various implants, such as bone anchors used in spinal operations. For example, one embodiment of an implant holding system can have an outer tube, an inner tube that can be disposed within the outer tube, and an implant holder that can be disposed within the inner tube. An individual bone anchor that has various configurations and sizes can be disposed within the holder, and the holder can engage the bone anchor to assist in maintaining an orientation of the bone anchor relative to the holder.

Disclosed is a system and method for tracking an instrument. The instrument may be tracked with one or more trackable members. The trackable members may be held relative to a handle to which the instrument is attached.

The disclosure relates to medical devices and methods of manufacturing medical devices. An orthopedic screw includes a shaft having a proximal end, a distal end, a body extending between the proximal end and the distal end, and a longitudinal axis. A distal thread on an external surface of the shaft extends around the longitudinal axis. A head portion includes a series of cutting teeth that lie on a plane that is perpendicular to the longitudinal axis of the shaft. A distal tip portion defines a cutting edge.
