A robotic system for use in performing an arthroplasty procedure of a patient is provided. The robotic system includes a robotic mechanism, a cutting tool coupled to the robotic mechanism for resecting a portion of a bone of the patient through an incision in the skin of the patient, and a computer coupled to the robotic mechanism and configured to control the robotic mechanism. The robotic system also includes at least one navigation member positionable into engagement with tissue in the patient, an optical system coupled to the computer, a position sensor configured to provide movement information of the robotic mechanism relative to the bone, and an interface coupled to the computer, the interface configured to operate the computer.

A tool set for preparing a joint, inserting an implant or removing an implant from a joint in an open or less invasive procedure generally comprises a set of nested tools, pin guides, jigs, and/or immobilization elements. The nested tool set comprises at least one pin and at least one cannulated tool. The cannula can comprise tangs that project from the distal end of the cannula. The tangs can be offset such that drilling removes different amounts of bone relative to drilling through a centered drill guide. The cannulated tool kit can comprise at least one tool guide/cannula, drill bits/reamer, syringe, and/or inserter. At least one cannula is positioned over and around the pin position into the joint. The channel of the cannula guides the other tools into the joint.

Devices and methods for preparing a surgical site, and in particular vertebral members, which may include a retractable tool and an actuator. The tool may include distal and proximal members. A distal side of the distal member may be fixed in a longitudinal direction and pivotable at a point of rotation. A proximal side of the proximal member may be pivotably connected to the actuator. In a retracted position, the distal member may be pivotably connected to the proximal member longitudinally in between the point of rotation and the proximal side of the proximal member. Moving the actuator in a distal direction may push the proximal member and the distal member such that the proximal member pivots with respect to the actuator and distal member, the distal member pivots with respect to the proximal member and point of rotation, and the proximal member and distal member move laterally outward.

A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be introduced over the first, advanced along a second longitudinal axis parallel to but offset from the first. A third dilator tube may be introduced over the second, advanced along a third longitudinal axis parallel to but offset from both the first and the second. An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.

A system to provide weight bearing simulation includes a plate; a strap to hold the plate to a foot; and a device configured to mount to the plate and adjust a position of the foot to the plate.

A system comprises an inflatable bone tamp including a plurality of linearly aligned expandable bodies. The system further comprises an elongated tubular shaft extending through the plurality of linearly aligned expandable bodies. The elongated tubular shaft includes a shaft wall and an interior partition structure. The system further comprises a plurality of channels extending through the shaft, each of the channels formed by a segment of the shaft wall and the interior partition structure and each of the channels in communication with the respective one of the plurality of expandable bodies via openings in the shaft. Each of the expandable bodies is independently inflatable.

The invention relates to a method of creating a curvilinear cavity within a vertebral body or other body structure. The invention also relates to devices that may be used to perform the steps to create the curvilinear cavity.

A robotic system for performing an arthroplasty procedure of a patient is provided. The robotic system includes a robotic mechanism including an adaptive arm, an oscillating saw coupled to the robotic mechanism and configured to resect a portion of a bone of the patient. The robotic mechanism is configured to control movement of the saw during the resection. The system also includes a computer coupled to the robotic mechanism which is configured to control the robotic mechanism. The robotic mechanism is configured to position a prosthetic implant relative to the bone. The system also includes an electric motor coupled to the robotic mechanism and the computer. The electric motor is configured to facilitate movement of the robotic mechanism. The system also includes a position sensor configured to provide movement information of the prosthetic implant relative to the bone. The system also includes an adaptive arm interface coupled to the adaptive arm and the computer wherein the adaptive arm interface is configured to operate the computer.

The present invention relates to a series of orthopedic plates for use in repair of a bone. The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and either one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge.

Embodiments include a robotic mechanism that may be utilized to position prosthetic implants in a patient's body. During joint replacement surgery and other surgical procedures, prosthetic implants may be placed in a patient's body. The robotic mechanism may be utilized to control movement of a cutting tool during resection of bone in a patient's body. The robotic mechanism includes a programmable computer which is connected with the force transmitting member by a motor. A force measurement assembly is connected with the force transmitting member and the computer. The output from the force measurement assembly is indicative of a resistance encountered by the force transmitting member. A position sensor is connected with the force transmitting member and the computer. The position sensor has an output indicative of the position of the force transmitting member.
