A hybrid radiolucent screw having radiopaque components and radiolucent components, which collaboratively define a tip of the screw and a head of the screw. In this manner, distortion is minimized during fluoroscopy or radiography of the screw while visualization of the screw and surrounding area is enhanced.

A system and method for reducing spondylolisthesis. The system includes a bracket comprising a first opening and a second opening, a first and second rod, and a first and second knob. The system may be placed onto a patient's back, the rods may be inserted through the first opening and the second opening and further into a first vertebral part and a second vertebral part. Tightening of a first knob and a second knob on the first and second rod allow for repositioning of the vertebra. Once repositioned, an interspinous implant may be inserted into the interspinous process space, connecting the vertebrae.

A puncture-resistant radiolucent operating surface apparatus includes a flat radiolucent and puncture-resistant surface configured to cover the detector of an intraoperative imaging machine, and downwardly extending sidewall flanges that are connected to said flat surface and that conform to the sides of said detector.

A head-holder support for attaching a medical head-holder to a patient table is provided that has a rigid base body, an adjustable and lockable head-holder interface at the base body, which is adapted to adjustably couple the head-holder to the base body by providing at least three degrees of freedom for the spatial relative position between the head-holder and the base body, wherein the at least three degrees of freedom are lockable so as to establish a rigid coupling between the head-holder and the base body, and at least one robotic arm interface at the base body, which is adapted to provide a rigid coupling between a robotic arm and the base body.

A location pad includes multiple field-generators and a frame. The multiple field-generators are configured to generate respective magnetic fields in a region-of-interest of a patient organ, so as to measure a position of a medical instrument in the region-of-interest. The frame is transparent to an X-ray radiation, and is configured to fix the multiple field-generators at respective positions surrounding the region-of-interest.

The present disclosure relates generally to the field of medical devices and establishing access to the renal capsule. In particular, the present disclosure relates to devices and methods for performing a percutaneous nephrolithotomy (PCNL) procedure accurately and efficiently while minimizing exposure of the medical professional to harmful radiation.

A surgical instrument assembly includes a support frame system, and a surgical tool engageable with the support frame system. The support frame system is adapted for providing a surgical tool attachment and articulation locus that is maintained during the course of a surgical procedure to direct a fixed and repeatable delivery path for introduction and manipulation of one or more surgical instruments and implants at a surgical site in or on the patient's anatomy. The delivery path can be substantially curvilinear along an arc that is defined by a radius of curvature and length defined by the surgical tool, and a predetermined range of articulation of the tool at the articulation locus.

A radiolucent, 3-D printed soft tissue retractor includes an elongate, curved support body having a long central axis that exceeds the length of a short, transverse axis. A bone engaging concavity is provided on a first side of the body. A concave soft tissue retracting surface is provided on a second side of the body. An inflection point is provided on the body in between the bone engaging concavity and the soft tissue retracting surface. The soft tissue retractor is configured to cooperate with a second soft tissue retractor and a backing plate to retract tissue and stabilize bones during a surgical distal radius fracture repair.

The biocompatible lattice structures and implants disclosed herein have an increased or optimized lucency, even when constructed from a metallic material. The lattice structures can also provide an increased or optimized lucency in a material that is not generally considered to be radiolucent. Lucency can include disparity, maximum variation in lucency properties across a structure, or dispersion, minimum variation in lucency properties across a structure. The implants and lattice structures disclosed herein may be optimized for disparity or dispersion in any desired direction. A desired direction with respect to lucency can include the anticipated x-ray viewing direction of an implant in the expected implantation orientation.

A surgical retractor including a blade molded from a polymer having at least a predetermined flexural strength, a handle, and a deepened portion connecting a proximal end of the blade to the handle, wherein the deepened portion increases in depth from the proximal end of the blade toward the handle, and wherein the blade, being molded from the polymer, and the deepened portion are configured such that the blade deforms less than 10 mm under 15 lbs of force applied thereto
