Cutting Edge Spine sacral-iliac (SI) joint fusion system, EVOL-SI, is available to the market. It features surface modification to improve osseointegration through optimized hydrophilicity and surface chemistry, mediating bioactivity and influencing tissue regeneration to yield early bone formation, improved mechanical stability, with faster fusion and stronger fixation.
4WEB Medicalcan begin marketing its Cervical Spine Truss System-Stand Alone (CSTS-SA) interbody fusion device. It has an open architecture, Advanced Structural Design that incorporates the company’s Truss Implant Technology to simulate cellular activity at the surgical site. 4WEB Medical’s manufacturing process creates a hierarchical surface roughness with features that span from the macro to nano scale. In-vitro testing has shown that stem cells attached to 4WEB’s titanium implant surface exhibited increased gene expression of certain osteogenic markers when compared to smooth titanium and PEEK.
OrthoPediatrics Corp.’s pediatric-specific system to treat fractures and deformities of the foot and ankle, PediFoot Deformity Correction System, is the company’s first system to incorporate the StarLoc variable angle locking technology, featuring a star-shaped design to offer five points of fixation. Consisting of implants and instrumentation to increase procedure throughput, PediFoot features the thinnest plates in its portfolio.

Automatic focus, fast inspection; Updated control panel; CAD/CAM suite offers smoother surfaces; Swiss-type automatic lathe
Haimer's Microset UNO Autofocus automatically focuses on the cutting edge for quick measurement, delivering ±2µm repeatability and 2µm spindle runout. The system includes 4° x 90° and 3° x 120° motor-driven indexing, Edgefinder, release-by-touch, spindle brake, vacuum clamp, a cabinet with storage for 6 adapters, and a 10-point touch screen.
Eldorado gundrilling machine’s control panels feature improved hardware and software. The larger screen provides for larger graphics and easier-to-read menus, and touchscreen capabilities improve menu navigation. A keypad replaces pushbuttons, making the panel more durable and easier to use in a shop floor setting.
The control also features CNC G-Code programming capability so customers can write their own programs, improving machine flexibility with variable feeds & speeds, drilling peck cycles, and dwell times. An external keyboard connects via USB.
The control is available as a retrofit for existing Eldorado gundrilling machines.
hyperMILL 2019.2 updates improve high-precision 3D finishing, 5-axis tangent machining, high-performance turning, and CAD-for-CAM technologies.
The 3D shape Z-level finishing cycle offers a high precision surface mode option for ultra-smooth surfaces with tolerances in the micron range. A smooth overlap function manages transition regions for steep and shallow machining with a small overlap, including a slightly lifted cutter, resulting in perfect finishes.
The hyperCAD-S global fitting function integrates directly into the CAM strategy for 5-axis tangent machining and multiple faces can combine into one with a controlled ISO orientation. Dedicated CAD utilities streamline CAM programming and provide tested, proven methodologies.
The SX-38’s Swiss-type, slant-bed, automatic lathe delivers rigidity for turret-mounted tooling. The servo-driven B-axis is for positioning or surfacing difficult- to-generate designs, while axis-unit support on both ends enables heavier cuts with fine finishes. When a part doesn’t require a guide bushing, it can be removed to allow for a maximum machining diameter of 42mm.
Swiss researchers have developed a new method for producing malleable microstructures – enabling vascular stents that are 40x smaller than previously possible. Such stents could be used to help widen life-threatening constrictions of the urinary tract of gestating fetuses.
Approximately 1 in every 1,000 children develop a urethral stricture, sometimes when they are still in the womb. To prevent life-threatening levels of urine from accumulating in the bladder, pediatric surgeons have to surgically remove the affected section of the urethra and sew the open ends of the tube back together. A stent inserted to widen the constriction would be less damaging to the kidneys while the fetus is still in utero.
Stents successfully treat blocked coronary vessels, but a fetus’ urinary tract is much narrower in comparison. Conventional methods couldn’t produce stents with small enough dimensions, which is why Kantonsspital Aarau pediatric surgeon Gaston De Bernardis approached the Multi-Scale Robotics Lab at ETH Zurich. The lab’s researchers have developed a method that produces highly detailed structures measuring less than 100µm in diameter.
Indirect 4D printing
“We’ve printed the world’s smallest stent with features 40x smaller than any produced to date,” says Carmela De Marco, lead author of the study and Marie Sklodowska-Curie fellow in Bradley Nelson’s research group.
The researchers use heat from a laser beam to cut a three-dimensional template – 3D negative – into a micro-mold layer that can be dissolved with a solvent. They then fill the negative with a shape-memory polymer and set the structure using ultraviolet (UV) light. Finally, they dissolve the template in a solvent bath and the three-dimensional stent is finished.
It’s the stent’s shape-memory properties that give it its fourth dimension. Even if the material is deformed, it remembers its original shape and returns to this shape when warm. The extra dimension generated the process’ name – indirect 4D printing.
“The shape-memory polymer is suitable for treating urethral strictures. When compressed, the stent can be pushed through the affected area. Once in place, it returns to its original shape and widens the constricted area of the urinary tract,” De Bernardis explains.
These stents are still a long way from finding real-world application. Before human studies can be conducted, the stents must first be tested in animal models.
Initial findings are promising, “We firmly believe that our results can open the door to the development of new tools for minimally invasive surgery,” De Marco concludes.
DGST pneumatic mini slides offer a small footprint, high feed force, precision operation, and ease of installation for precision handling, press fitting, pick and place, and electronic and light assembly applications.
A backlash-free piston rod/yoke connection extends the slide’s service life. Maintenance-free twin-piston drives and high force capacity recirculating ball bearing guides provide the DGST with 2x the power of other slides – from 7.6 lbf to 132.6 lbf (34N to 590N) at 6 bar.
Cushioning and proximity sensors do not extend beyond the slide’s footprint. Three cushioning options are available. Two slides can be piggybacked in minutes by bolting the units together – adaptor plates are not needed. Locating port connections, end-position sensing, and precision end-position adjustment on one side contributes to ease of installation.
“This reorganization will ensure that Faulhaber Micromo can flourish and grow as a Faulhaber family-owned company for generations to come with one name and one vision which will enhance the benefit to our high-tech customers,” says Micromo President Ping Faulhaber.
The division remains under family ownership, including Ping Faulhaber, as a 100% subsidiary of Faulhaber Drive Systems, headquartered in Schönaich near Stuttgart, Germany.

On-board security includes a built-in firewall and virtual private network (VPN) to help users address cyber-attacks. All panels have future-ready Linux operating systems and support HTML5 technology.
Each touch panel features an energy-saving standby function, integrated sensors for automatic brightness adjustment, and an easy-to-mount design.
Mikron’s VX high-precision rotary transfer machine is a flexible production system for cost-efficient manufacturing of various batch sizes. The machine can pre-machine directly on wire or bar stock before cut-off and subsequently clamp on pre-machined surfaces. Subsequent operations can then be performed unattended, producing ready-to- assemble components. Maximum workpiece dimensions are 40mm x 40mm x 80mm (40mm x 40mm x 160mm, optional).
