An assembly comprising a drive gear coupled to a shaft and a dial. The drive gear is configured to rotate along a first axis based on movement of the dial. The assembly includes a first linking member located along a second axis and configured to rotate about the second axis based on contact with the drive gear as the drive gear is rotated. The assembly includes a second linking member located along the second axis and configured to rotate about the second axis based on rotation of the drive gear and a coupling between the first linking member and the second linking member. The assembly includes a linking member selector configured to rotate about the first axis and for selecting at least a position corresponding to the first linking member that causes the coupling between the first linking member and the second linking member.

A method for robotic assisted surgery. The method includes capturing a plurality of poses of a surgical tool coupled to a robotic device at a surgical site. The plurality of poses correspond to instances of a final placement of surgical implants at the surgical site. The method also includes determining a plurality of positions of the surgical implants located at the surgical site based on the captured plurality of poses. The method also includes generating a bend curve having a plurality of bend points based on the determined plurality of positions of the surgical implants. The method also includes generating bending instructions for bends to be performed on a linking device configured for attachment to the surgical implants.

An apparatus for inserting implants in a bone comprising a frame having a cartridge receiving chamber and a barrel. A cartridge defining a plurality of chambers is positioned in the cartridge receiving chamber so the chambers are selectively alignable with a longitudinal passage of the barrel. At least one instrument is positioned in one of the chambers, and a plurality of implants is positioned in the other chambers. A drive assembly is engageable with the instrument and the implants. The drive assembly is slidably and rotatably disposed in the frame and is moveable between a retracted position, an engaging position wherein the distal end of the drive assembly is positioned to engage the selected one of the instrument and the implants, and an extended position wherein the drive assembly extends through the chamber to transport the selected one of the instrument or the implant from the chamber to the distal end of the barrel.

A non-intrusive bone anchor for attachment to vertebral laminar processes with a main body which has a lower fixed jaw; a connecting portion to said lower fixed jaw, a bore hole providing basis for an axis from one side of said connecting portion to the other, and a threaded two ring clamp where each ring has an inner threaded surface with a threaded axis; An externally threaded shaft with a first and second end, where said first end has an internal torquing indent and a portion adjacent thereto for a locking mechanism to engage the outer portion of the clamping ring and said first end has a fixation protuberance. An upper jaw that cooperates with said externally threaded shaft and engages bone between said upper jaw and said lower fizzed jaw forming a diagonal across a clamped bone body; and an inter-anchor connector comprising an axis with a first connector end and a second connector end where said first connector end has a rod portion and said second end has a tulip rod fixer portion.

A two-piece suspension pedicle anchor and its system and component-set is disclosed. The two-piece suspension pedicle anchor comprises a proximal piece and a distal piece that can rotate relatively. An external thread is arranged on the outer surface of the proximal piece, and a transverse through hole for an artificial ligament to pass through is arranged at the distal piece. As the two-piece suspension pedicle anchor is rotated and gradually locked into the bone, only the proximal piece is rotated, and the distal piece with the artificial ligament is pushed down but not rotated; in addition, the artificial ligament will be brought into the bone along with the distal piece and sandwiched between the outer surface of the proximal piece and the bone, that is, the artificial ligament will be sandwiched and fixed between the anchor-bone interface without wrapping around the outer surface of the proximal piece.

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. More specifically, the application describes instruments and methods for building a posterior fixation construct across one or more segments of the spinal column in a minimally invasive fashion.

A length adjustable modular screw includes a neck assembly and a shank. The neck assembly has proximal and distal ends and includes an expander component and a collet component that are slidably engagable by insertion of the expander component in a through channel of the collet component along a common axis. The length adjustable modular screw also includes a shank suitable for insertion and retention within a bone, the shank including a threaded portion between proximal and distal ends and a socket adapted to coaxially receive at least a portion of the distal end of the neck assembly. The length adjustable modular screw has a length that is selected by splaying at least a portion of the distal end of the engaged expander and collet components of the neck assembly within the socket of the shank.

A surgical instrument comprises a first member including a drive engageable with a first mating surface of a bone fastener. A second member is rotatable relative to the first member and includes an element engageable with a second mating surface of the bone fastener. An actuator is connected with the second member and includes visual indicia of engagement of the element with the second mating surface. Systems, spinal implants and methods are disclosed.

Embodiments are directed to spinal treatments and, more particularly, to a fenestrated pedicle nail, wherein the pedicle nail performs as an anchored system for pedicle instrument constructs that prevents fracturing from over-compressing of bone of poor quality. Embodiments include a pedicle nail comprising a shank and a nail head. The shank may comprise a proximal end and a distal bone engagement end. The nail head may be disposable on the proximal end of the shank, wherein the nail head may threadably engage the proximal end thereof. The nail head may have external bone threads.

Briefly, the invention relates to a surgical tool and method for forming a pilot bore by inserting a guide wire into bone. The surgical tool is constructed and arranged for use in conjunction with X-ray or ultrasound machines. More particularly, the device includes a cannulated hand grip and driving tool used for the rotation of a bone or pedicle screw into bone. The rear portion of the hand grip includes a slide assembly that is suited to grip a guide wire. The slide assembly includes a user adjustable stop to control the sliding movement of the guide wire. The rear surface of the slide is constructed to be impacted with a hammer or similar device, whereby the stop prevents the guide wire from penetrating the bone further than desired. Should it be desired that the wire be retracted, a jack member is included to allow the wire to be precisely retracted. The hand grip is securable to various surgical driving tools for the purpose of providing the ability to cooperate with various brands of pedicle screws and other surgical implants for spinal procedures.
