A surgical system includes a robotic device, and a surgical tool coupled to the robotic device and comprising a distal end. The system further includes a neural monitor configured to generate an electrical signal and apply the electrical signal to the distal end of the surgical tool, wherein the electrical signal causes innervation of a first portion of a patient's anatomy which generates an electromyographic signal, and a sensor configured to measure the electromyographic signal. The neural monitor is configured to determine a distance between the distal end of the surgical tool and a portion of nervous tissue based on the electrical signal and the electromyographic signal, and cause feedback to be provided to a user based on the distance.

An attachment apparatus is disclosed to secure a medical alignment device to align a tool. The attachment apparatus may include a base wall providing a base alignment surface for abutting or positioned adjacent a first portion or first surface of the medical alignment device. The medical alignment device operable to provide an alignment of a tool, such as a three-dimensional alignment angle of the tool, and to provide a notification when the medical alignment device aligned with the tool as desired. The attachment apparatus may include a first side wall providing a side alignment surface for abutting or adjacent a second portion or surface of the medical alignment device; and an alignment support configured to align with a portion of the tool. A method is disclosed for aligning a tool or object using an attachment apparatus.

A device for safely approaching vertebral disc space utilizing stereotactic guidance, clearing material from the disc space, a device for expanding the disc space, stereotactic methods for implant planning and monitoring articulating instrument end effectors and a device for implantation into the disc space for the purpose of fusion or disc replacement.

A surgical treatment system comprises a drill bit extending along a proximo-distal drill bit axis suitable for drilling a hole in the pedicle of a vertebra when the bit is rotated. The bit includes, successively along the drill bit axis, a distal end, a cylindrical drill centred on the drill bit axis for drilling the hole by cutting into and removing bone material from the pedicle to give a distal end portion of the hole a cylindrical shape, and a milling cutter for cutting bone material from the pedicle of the vertebra to give a proximal end portion of the hole a funnel shape gradually widening from the distal end portion of the hole. A pedicle screw extends along a proximo-distal screw axis and is designed to be screwed into the hole by being rotated after the drill bit has drilled the hole and has been removed from this hole.

A surgical instrument comprises a first member extending between a proximal end and a distal end configured for fixation with tissue. A second member defines a longitudinal passageway and is connected with a navigation component such that the distal end is disposable with the passageway at a selected distance from the navigation component. The navigation component is positioned relative to a sensor to communicate a signal representative of an orientation of the first member. A third member extends between a proximal end and a distal end. The third member is mountable with the first member along the orientation such that the distal end of the third member is engageable with the tissue. Systems, spinal implants, constructs and methods are disclosed.

The present disclosure in one aspect provides an adjustable depth drill guide comprising a trigger assembly further comprising a trigger and a primary actuating element and a telescopic rotational assembly which abuts the primary actuating element and further comprises an intermediate actuating element. The drill guide described herein allows a surgeon to adjust the depth of the drill guide using only one hand while in-situ.

A surgical system may include a conductive stylet with a distal end advanceable into bone material and a proximal end coupled to a stylet hub. A handle is non-removably attached to the stylet hub, and removably attachable to an insulative cannula hub. The cannula hub is non-removably attached to a conductive cannula that surrounds the stylet when the handle is attached to the proximal end of the insulative cannula hub. An outer insulative sheath is slideably engaged to insulative cannula hub, and has a radio-opaque distal tip. An electrical signal source may be applied to the stylet hub to conduct a pedicle integrity assessment. The handle and stylet may be removed from the cannula assembly, leaving the cannula assembly in place at the surgical site.

The invention relates to a system (8) for assisting a user in placing a penetrating device in tissue like a pedicle screw (7) in a vertebra’s pedicle. The system generates a virtual view (20) from a penetrating device tip perspective within the tissue in the direction of a path (21) through a model of the tissue. The virtual view is generated based on tracking information indicating a pose of the penetrating device, the model and the path, wherein the virtual view is configured such that it indicates a direction in which the user should move the penetrating device while placing it in the tissue. For instance, it can show a virtual tunnel (801) which is arranged along the path. If a user like a surgeon is provided with such a virtual view, the user can position the penetrating device along the path with a significantly increased accuracy.

A surgical spinal screw apparatus configured to facilitate safer spinal surgery and reconstruction via a pivoting tip. The apparatus is equipped with a tip which is configured to pivot about a pivot point which facilitates minor redirection of the apparatus when driven through bone such as a vertebra. The apparatus is geared towards finding a path of least resistance through the bone. As such, the tip is configured to pivot towards less dense pockets of bone as the screw is placed during surgery. A pedicle finder, a companion apparatus, is configured to facilitate placement of the spinal screw, and is similarly equipped with a pivoting tip. The spinal screw is threaded and is equipped with a hollow core to facilitate the passage of a guide wire to assist in placement and tension of the pivoting tip as needed.

A universal drill guide system includes a universal drill guide, interchangeable drill tubes, and interchangeable drill bits. Each interchangeable drill tube corresponds to one of the interchangeable drill bits, and can be detachably coupled to the universal drill guide. A cannulated drill with K-wire retention features a drill bit with a retention mechanism that prevents axial advancement of a K-wire during drilling. A drill removal tool includes a drill remover that can be placed around a drill bit to remove it from bone after a hole is drilled, while leaving a K-wire in place in the bone. A bone screw driver with K-wire retention includes a shaft that can be passed over a K-wire, a distal end for attachment to a cannulated bone screw, and a K-wire retention module for preventing advancement of the K-wire as the screw driver drives the cannulated bone screw into bone.
