Abstract: A retractor extension clip deployment system for use with a surgical retractor includes at least an extension clip adapted for engagement with the surgical retractor, the extension clip having proximal and distal ends, a deployment instrument, and a fluid transport assembly adapted to be affixed to the surgical retractor and comprising one or more tubes for transporting fluid including smoke removal.

Abstract: 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.

Abstract: A surgical guidance device is cannulated for passage of a guidewire or pin and includes a hand grip and differential control assembly for driving the guidewire or pin and differentially driving a screw, such as but not limited to a pedicle screw, into bone. The differential control assembly resides in a housing, and includes a differential control assembly for gripping and locking or releasing the guidewire or pin and effecting directional movement (relative to the user holding the surgical guidance device) either distally into the bone or proximally away from bone to thereby drive or retract the guidewire. The differential control assembly also allows distal or proximal drive of a screw, such that one or both the guidewire and screw can be passed proximally or distally alone or together.

Abstract: An implantable modular plate system for stabilizing adjacent vertebral bodies in a cervical spine includes at least two plate segments aligned or connected together so as to form a connection at and along adjacent ends. At least one of the plate segments includes a flange at an engagement end and at least one of the plate segments including a flange recess at an engagement end, the flange being configured for overlay engagement with the flange recess when the at least two plate segments are engaged. The plate segments are pivotable out of plane with one another at a common axis of rotation traversing overlapping portions of the adjacent ends and are constrained from rotation by the flanges such that the rotation of each plate segment is limited to up to 90 degrees of rotation away from the contact surfaces of the flange and flange recess.

Abstract: A tubular retractor securement frame is disclosed including a mounting bracket, two flexor arms, and a device emplacement oriented to receive and hold in-place a surgical tool. The mounting bracket includes an elastically deformable plate, rails extending about orthogonal from the elastically deformable plate and about parallel to one another, and receptacles facing one another in the rails which are arranged to receive a retractor arm extending from a tubular retractor at a fixed angle. The flexor arms extend from the mounting bracket adjacent to the rails. The flexor arms are positioned so as not to occlude visualization through the tubular retractor and such that applying pressure to flex the flexor arms toward one another shifts the rails to accept or remove the retractor arm into or from the receptacles, and releasing the pressure reverts the rails so as to inhibit the retractor arm from being inserted or removed.

Abstract: An adapter for an electrosurgical instrument includes a socket and a stabilizer extending from the socket. The socket includes a mounting surface having a geometry arranged and disposed to accept a distal end of the electrosurgical instrument, and at least one retaining surface, which arranged and disposed to interact with a conformation of the electrosurgical instrument when the socket is mounted onto the electrosurgical instrument such that the socket mounts non-rotatably.

Abstract: An illuminated translucent endoscopic probe system includes a handle and rigid elongate body for passage into and through hard and/or bony tissue and includes an integrated camera and light source positioned distally from the handle and adjacent a distal tip that includes a transparent driving head. The system provides real time visualization at the distal end as it passes into and through tissue.

Abstract: The invention is directed in various aspects to a system including anchors, anchor components, and anchor assemblies and subassemblies that are adapted for attachment to a bony structure of a clinical subject. For example, two or more such anchors in the form of screws may be affixed to bones, for example, vertebral structures such as the pedicle, and each anchor is connected to a stabilizer such as a surgical rod that is inserted between the anchors. The anchors and assemblies are novel in many respects owing to their modular nature, which in contrast to conventional systems, allows the anchors to be provided to a surgeon in modular, subassembly and fully assembled form to enable a broad array of choices in devising the optimal plane for surgical bone fixation.
