A surgical hammer that includes a handle, a shaft extending from the handle and a hammer head connected to the shaft. The hammer head includes a slot extending through the hammer head and in fluid communication with a distal end of the hammer head, a first internal cavity within the hammer head spaced laterally from the slot, and a second internal cavity within the hammer head spaced laterally from the slot.

A bi-directional fixating transvertebral (BDFT) screw/cage apparatus is provided. The BDFT apparatus includes an intervertebral cage including a plurality of internal angled screw guides, a plurality of screw members, and a cage indentation adjacent to the screw guides that independently or supplemented by other screw locking mechanisms prevents the screw members from pulling out of the internal angled screw guides. The internal angled screw guides orient a first screw member superiorly and a second screw member inferiorly. The intervertebral cage is adapted for posterior lumbar intervertebral placement, anterior lumbar intervertebral placement, anterio-lateral thoracic intervertebral placement, or anterior cervical intervertebral placement.

A tool for manipulating the position of an implantable medical device. In some embodiments the tool includes a readily releasable grasping feature that securely couples the implant to the tool while the implant is being manipulated. Preferably, the user can simply release the implant from the tool. The tool in other embodiments includes an internal pathway for accommodating non-linear implants, such as curved rods, wires, or nails. In yet other embodiments the tool has multiple handles, each handle being adapted and configured to permit manipulation of the implant in a single predetermined orientation, but with alternative handles for grasping in different hand orientations. Still further embodiments pertain to a kit having a tool and a plurality of collets, each collet being adapted and configured to grasp a different size of implant, but each collet having identical tool coupling features such that any collet in the kit can be used with the single tool. Still further, yet other embodiments pertain to tools having quick release mechanisms for the acceptance or removal of a collet, and some include external features for preventing inadvertent release of the collet when coupled to an implant.

An osteotome is provided that is designed for implanting and extracting medical device implants. The osteotome includes a handle, a blade attachment assembly about a first end of the handle for receiving a blade, and a wing assembly about a second end of the handle opposite the first end. The wing assembly further includes a wing extending outwardly from the handle.

A guide sleeve for use in anchoring a fixation member to an intramedullary nail and to bone includes a sleeve body that is elongate along a central axis and has an internal surface that defines a bore extending along the central axis to a distal end of the sleeve body. The sleeve body also defines a plurality of guide channels that are each recessed radially outwardly from the internal surface and each include a helical proximal portion and a linear distal portion that extends from the helical proximal portion toward the distal end. The linear distal portion is parallel with the central axis. The guide channels are configured to receive respective complimentary followers of an instrument for driving the fixation member through the bore and subsequently through the intramedullary nail and into the bone.

A force-limiting and damping device has a body, a tapping element, a shock-absorbing element, and a limiting module. The body has a connecting segment and a holding segment. The tapping element is connected to the body to move relative to the connecting segment and has a mounting segment, a tapping segment, and a fixing segment. The mounting segment is movably connected to the connecting segment. The tapping segment is disposed on an end of the mounting segment below the connecting segment. The fixing segment is connected to the mounting segment and abuts the connecting segment. The shock-absorbing element is mounted on the mounting segment and abuts the connecting segment and the tapping segment. The limiting module is mounted between the body and the tapping element and has a force-limiting element mounted between the mounting segment and the connecting segment to provide a force-limiting reminder effect and a damping effect.

A method for performing an efficient and thorough percutaneous discectomy includes making into the patient a percutaneous incision, which is a small stab wound, no more than approximately 10 mm in length. A stimulated combination neuro-monitoring dilating probe is passed through an approximately 10 mm or less skin incision and into a patient's disc space to establish a safe path and trajectory through Kambin's Triangle. Once a neuro-monitoring dilating probe is in the disc space, a second dilator is placed over the neuro-monitoring dilating probe and impacted into the disc space. Neuro-monitoring dilating probe may then be removed. An access portal optionally combined with a force dissipation device may then be placed over the second dilator and into the disc space. The second dilator is removed and then discectomy instruments may be placed through the access portal to perform the discectomy.

A microfracture impactor tool including a housing defining a central axis, the housing can include a proximal portion and an opposite distal portion. A handle can be connected to the distal portion of the housing and can extend outward therefrom. The impactor tool can include a grip that is pivotably connected to the proximal portion of the body near the handle. The impactor tool can include an impactor wire configured to impact bone, and a guide tube connected to the distal portion of the housing that is configured to retain the impactor wire.

A multimodal abrading device for preparing a sacroiliac joint (SI Joint) to receive a graft implant. The abrading device comprises an abrading head having abrading surfaces on a first pair of opposing sides, the abrading surfaces configured for decorticating the cortical bone of the SI Joint. The abrading head further comprises an open tip having a cutting edge configured to cut bone tissue in the SI Joint. The abrading device further comprises a slide hammer assembly at a proximal end of the abrading device, the slide hammer assembly having a released position that enables operation of the slide hammer assembly, and a locked position that prohibits operation of the slide hammer assembly.

An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, an impacting element, an anvil element, and a broach adapter. The compression piston may cause the impacting element to apply controlled force on a broach adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The tool may further comprise a detent for holding the impacting element in a position until a sufficient pressure is applied to release the impacting element. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool.
