Method, device, and system for bone fixation

The presently disclosed invention relates to devices and methods for conducting bone surgery on an animal using a bone surgery tool comprising a base, a fixed arm fixed to the base, the fixed arm including a shoulder and a jaw, a sliding arm releasably fixable to the base, the sliding arm including a head that receives an implant and a cartridge in a slot, the method comprising hooking the bone with the jaw, moving the head toward the jaw capturing the bone, accessing the bone with a drill through cartridge bores in the cartridge, and drilling holes, accessing the bone with a self-shearing screw attached to a screw driver through cartridge bores in the cartridge, and attaching the implant to the bone, and moving the head away from the jaw releasing the bone.

Tool system for removing prosthetic cement from a bone of a patient undergoing a joint prosthesis replacement operation

A method for providing a tool system for removing prosthetic cement from a bone of a patient undergoing a joint prosthesis replacement operation includes scanning the patient in the area of the joint prosthesis to obtain a profile of a line of intersection of a prosthetic cement/bone interface at its intersection with a longitudinally pre-selected plane; providing a guide member shaped as a stem of the prosthesis in a prosthetic cavity located in said prosthetic cement; and providing a cutting tool for forming a running cut through the prosthetic cement along the line of intersection. A stem of the cutting tool includes two protrusions along the length thereof. A guide member includes two grooves which each engage one of said protrusions. Grooves are profiled so the outer end of the stem is forced to follow a path corresponding to the profile of the line of intersection of the cement/bone interface.

ORTHOPAEDIC SURGICAL SAW ASSEMBLY FOR REMOVING AN IMPLANTED GLENOID COMPONENT AND METHOD OF USING THE SAME

A surgical instrument for removing an implanted glenoid component from the glenoid of a patient includes a protective cannula and a flexible wire saw. The flexible wire saw is positioned in the protective cannula such that both ends of the flexible wire saw extend out of one end of the protective cannula, with a portion of the middle section of the wire saw forming a loop that extends out of the other end of the protective cannula. Surgical methods for the use of such a surgical instrument are also disclosed.

Nondestructive autograft extracting device for autologous osteochondral transplantation

Systems and methods for harvesting tissue from a donor site include first and second conduits through which a flexible saw component is guided. Certain embodiments include a mechanism which facilitates insertion of a flexible cutting member component parallel to a transverse plane and slicing a graft parallel to the coronal plane to extract the graft.

Devices and methods for treating tissue

Described herein are devices, systems and methods for treating target tissue in a patient's spine. In general, the methods include the steps of advancing a wire into the patient from a first location, through a neural foramen, and out of the patient from a second location; connecting a tissue modification device to the wire; positioning the tissue modification device through the neural foramen using the wire; modifying target tissue in the spine by moving the tissue modification device against the target tissue; and delivering an agent to modified target tissue, wherein the agent is configured to inhibit blood flow from the modified target tissue. In some embodiments, the step of modifying target tissue comprises removing target tissue located ventral to the superior articular process while avoiding non-target tissue located lateral to the superior articular process.

Orthopaedic surgical saw assembly for removing an implanted glenoid component and method of using the same

A surgical instrument for removing an implanted glenoid component from the glenoid of a patient includes a protective cannula and a flexible wire saw. The flexible wire saw is positioned in the protective cannula such that both ends of the flexible wire saw extend out of one end of the protective cannula, with a portion of the middle section of the wire saw forming a loop that extends out of the other end of the protective cannula. Surgical methods for the use of such a surgical instrument are also disclosed.

CUTTING GUIDE SYSTEMS AND METHODS

Cutting guide systems for adjusting and stabilizing cutting devices are disclosed. Example cutting guide systems may be used in orthopedic surgery. In some examples, a cutting guide system comprises a support mount, a joint, and a cutting instrument support, wherein the joint permits the cutting instrument support to be adjusted with respect to the support mount. The joint may permit the cutting instrument support to be rotated about at least two axes. The joint may be lockable to hold the position of the cutting instrument support. A cutting instrument may be pivotable and/or movable in a longitudinal direction with respect to the cutting instrument support. In some examples, a cutting guide system comprises a track, wherein a cutting instrument support is connected to the track in a manner that permits the cutting instrument support to move along a path. Methods of using cutting guide systems are also disclosed.

Surgical saw with sensing technology for determining cut through of bone and depth of the saw blade during surgery

Sensing technology methods related thereto for determining cut through of bone and a depth of penetration of a working portion of a surgical instrument (e.g., an oscillating saw blade in a cut). A first sensor outputs a first signal representative of a displacement of the cutting edge of the saw blade in the cut. A second sensor outputs a second signal representative of a force applied to the cutting edge of the saw blade. As such, monitoring the first and/or second sensor may allow for the saw to be stopped upon completion of a cut (e.g., when the saw passes completely through a medium to be cut or upon reaching a predetermined depth for the cut).

Decortication Instrumentation for Posterior Sacroiliac Joint Fusion
20220071644 · 2022-03-10 · ·

A drill-less method of stabilizing a sacroiliac joint using a multimodal abrading device to create a rich environment for bony fusion. The unique decortication instrument includes an integral slap hammer assembly joined with a rasp-box osteotome tooling head to simultaneously remove cartilage from the joint while preparing the sacrum and ilium down to bleeding bone. Subsequent to joint preparation, an implant with a large bone graft window may be implanted into the prepared SI joint through a specially designed access cannula.
