A bone graft delivery system can include an elongate tube, a handle having a trigger, and a tip. The trigger is actuated to deliver bone graft material through the tube. The tip has one or more openings to deliver the bone graft material to a desired location and includes a surface suitable to act as a rasp for decorticating bone. A method for delivering bone graft material to a desired surgical location includes providing a bone graft delivery device, positioning the device adjacent the surgical location, decorticating bone, and delivering bone graft material to the surgical location.

A surgical instrument including an articulating region. An outer tube and an inner tube are axially fixed to one another distal to the articulating region and axially movable relative to one another proximal to the articulating region. Relative movement of the inner and outer tubes provides for articulation of the articulating tube assembly to a curved configuration. A working tool may be removably directed through a central cannula defined by the inner tube. The working tool may include a shaft having a flexible region configured to be arranged within the articulating region. The shaft may rotate within the inner tube with the articulating tube assembly in the curved configuration. The working tool may include a housing hub configured to be coupled with a handle to removably position the flexible region within the articulating region. Multiple working tools may be interchangeably directed through the central cannula.

A handheld surgical device with a working portion driven by a motor, wherein the working portion is contained in a concave-shaped portion when it is not activated, and the working portion becomes exposed from the concave-shaped portion when it is activated. The activation of the working portion can be controlled by a switch located at a handle portion of the handheld surgical device. The handheld surgical device includes a concave-shaped portion with a cutting edge, which is not driven by the motor.

A cutting tool has a first annular member at a proximal end portion of the cutting tool, a second annular member at a distal end portion of the cutting tool, and a plurality of curved side panels extending between the first annular member and the second annular member and coupled to the first and second annular members. The curved side panels are arranged about an axis of rotation of the cutting tool to form a hollow, tubular cutting structure, and include a plurality of cutting teeth oriented in a circumferential direction about the axis of rotation.

A system and method for harvesting autologous tissue, mincing it into fragments that are visible and measureable when filtered, and delivering a portion of the tissue back into the patient without the need to directly touch the tissue. During the same surgical procedure, the tissue can be mixed with a biocompatible agent before introduction into the repair site.

Surgical impact driver adaptors may be connected between a powered surgical instrument and a driven surgical device when performing surgical procedures, such as those involving the implantation of a surgical implant into bone, for example. During surgical procedures, the surgical impact driver adaptors may limit a transfer of a rotational force from the powered surgical instrument to the surgical device until a sufficient axial force is applied to the impact driver adaptor from the powered surgical instrument.

The invention concerns a surgical drill bit able to be connected to a surgical tool, comprising a flexible stem. The invention also concerns a corresponding method to produce the surgical drill bit.

A flexible shaft includes a tubular body extending along a central longitudinal axis and having proximal and distal ends opposite one another. The flexible shaft also includes a slot defined by the tubular body and extending along a helical path around and along at least a portion of the body between the proximal and distal ends. The helical path extends around the portion of the body for a plurality of rotations. The slot defines at least two teeth adjacent one another along a direction parallel to the central axis. Each tooth of the two teeth has a feature. In some implementations, a line extending through center points of the features on the two teeth is angularly offset from the central longitudinal axis. In some implementations, a line parallel to the central longitudinal axis intersects a different point on each feature of the two teeth.

A device is disclosed that includes a bone stent positioned within a bony access channel formed within a vertebra. The bony access channel may extends from an outer end of the vertebra through an endplate. The device includes an end cap attached to a proximal end portion of the bone stent and is configured to, post-operatively, open to allow a reintroduction of a material to a spinal intradiscal space or intervertebral disc and to seal access to the spinal intradiscal space or the intervertebral disc after the reintroduction of the material.

A surgical device for cutting bone or tissue in a patient can include a cutting blade having a rigid portion, a flexible portion, and a liner to provide a seal to the flexible portion. The blade has an outer member and an inner member disposed within a lumen of the outer member. The inner member has a rigid portion and a flexible portion. The liner can be disposed within a lumen of the inner member and can engage the rigid portion such as to retain the liner adjacent to the flexible portion of the inner member.
