ORTHOPEDIC PLATE, ORTHOPEDIC DEVICE, METHOD OF COUPLING BONE SEGMENTS, AND METHOD OF ASSEMBLING AN ORTHOPEDIC PLATE
An orthopedic plate comprising a frame portion having a longitudinal body defining a longitudinal axis. The longitudinal body having at least one side arm extending from the longitudinal body transverse to the longitudinal axis. The frame portion also having a bearing rotatably coupled with the at least one side arm, wherein the bearing defines an opening configured to receive a fastener for fastening the orthopedic plate to a body. The bearing includes an outer surface that is eccentric to the opening such that a position of the opening with respect to the frame portion is adjustable as the bearing rotates.
METHODS AND APPARATUS FOR DEPLOYING SHEET-LIKE MATERIALS
Implant delivery systems for delivering sheet-like implants include a delivery shaft, an implant expander, a sheath, and a sheet-like implant. In some embodiments, the delivery shaft has a proximal end and a distal end. The implant expander is mounted to the distal end of the delivery shaft. The implant expander includes a central portion and a plurality of leg portions radiating from the central portion. The implant expander is evertable between an unstressed configuration in which a distal surface of the implant expander defines a concave surface, and a first compact configuration in which the distal surface of the implant expander defines a convex surface. The implant expander has a first lateral extent when the implant expander is free to assume the unstressed configuration. The sheath defines a lumen having a lumen diameter. At least a portion of the delivery shaft is slidably disposed in the lumen. The lumen diameter is smaller than the first lateral extent of the implant expander so that the sheath holds the implant expander in the first compact configuration when slidably disposed therein. The sheet-like implant overlays at least a portion of the distal surface of the implant expander with portions of the sheet-like implant extending between the leg portions of the implant expander and the sheath. Methods of treating a rotator cuff of a shoulder are also disclosed.
Variable angle blade plate system and method
A bone fixation system having a plate with an axle and a blade or “beam” configured to engage with the axle and reside proximate to a subchondral fragment of bone in upon installation of the plate. The beam is operable to rotate about the axle on the plate and reposition the subchondral fragment of bone.
Orthopedic implant and methods of implanting and removing same
Illustrative embodiments of orthopedic implants and methods for surgically repairing hammertoe are disclosed. According to at least one illustrative embodiment, an orthopedic implant includes a proximal segment comprising a number of spring arms forming an anchored barb at a first end of the implant, a distal segment extending between the proximal segment and a second end of the implant, and a central segment disposed between the proximal and distal segment.
Systems, devices, and methods for joint fusion
The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.
Orthopedic anchor assembly
An orthopedic assembly is described that comprises an orthopedic device, an anchor, and a locking mechanism. The orthopedic device can be a plate member having an aperture that is configured to receive the anchor. The anchor can include a head, neck and shank portion. The head portion can include a plurality of arms separated by grooves that are capable of splaying. The assembly is configured such that when the locking mechanism is inserted into the head portion, this causes expansion of the arms of the head. This expansion locks and secures the anchor to the orthopedic device. Various instruments are provided that can deliver the locking mechanism to the anchor, and can provide impact to lock functionality.
Combination reamer/drill bit for shoulder arthoplasty
An instrumentation kit for use in preparing a shoulder to receive a glenoid component in one embodiment includes at least one combination device, the combination device including a boring section configured to form a first bore in a glenoid, a drive section operably connected to the boring section, a reaming section positioned proximally from the boring section and operably connected to the drive section, the reaming section configured to ream a portion of the glenoid, and at least one drill guide configured to guide a drill bit and positioned so as to guide the drill bit to form a second bore at a location spaced apart from the first bore, wherein the reaming section and the boring section are positioned with respect to each other such that the boring section forms the first bore and the reaming section simultaneously reams a portion of the glenoid adjacent to the first bore.
INSERTION TOOL FOR FLIP ANCHOR CABLE SYSTEM INSERTION
An insertion tool for deploying a flip anchor cable, including: a mechanism having a safety button and a slider, wherein the mechanism is configured to apply a clamping force on a portion of the flip anchor cable when the mechanism is in a first position; an inner tube having a proximal end connected to the mechanism configured to house a second portion of the flip anchor cable; a handle including a safety button opening and a slider opening, wherein the handle is configured to enclose a portion of the mechanism; and an outer tube having a proximal end connected to the handle configured to receive the inner tube; wherein the mechanism is configured to decrease the clamping force on the flip anchor cable when the mechanism is in a second position and to deploy a flip anchor of the flip anchor cable in the second position.
Hammertoe implant and instrument
A bone implant comprising an elongate body having a first end and a second end coupled by a shaft is disclosed. The first portion is configured to couple to a first bone. The second portion comprises a first expandable section comprising at least one expandable feature. The first expandable section is configured to be received within a reverse countersink in a second bone in a collapsed state and to expand within the reverse countersink. The expandable feature couples to a bearing surface of the reverse countersink. A surgical tool comprising a shaft and at least one expandable cutting edge is disclosed. The shaft is sized and configured to be received within a canal formed in a bone. The expandable cutting edge is formed integrally with the shaft. The expandable cutting edge is configured to expand from a collapsed position to an expanded position for forming a reverse countersink.
SURGICAL APPARATUS, SURGICAL SYSTEM AND METHOD OF SETTING UP A SURGICAL APPARATUS
A surgical apparatus generates energy that is input onto an appliance. The appliance is one of an implant to be implanted in human or animal bone tissue by the input of the energy, and of a tool being an ultrasonic bone cutting and/or punching tool for cutting and/or punching living human or animal bone tissue by input of energy onto the implant in a surgical operation. The apparatus includes a control device and at least one handpiece, the handpiece being equipped to be held by a surgeon during the operation and to couple the energy into the appliance. The apparatus further includes a reading device equipped to read out, from an appliance data carrier, appliance data dedicated to the appliance. The control device checks, depending on the appliance data, whether the handpiece is suitable for the appliance and chooses operating parameters depending on the appliance data.
