Nerve Repair

Newrotex develops innovative silk-based medical
solutions for the nervous system.

The answer to “Can you repair nerves?” shouldn’t come with caveats. This is why Newrotex is set to disrupt existing approaches to surgical nerve repair. We’re on track to provide an alternative to autografts, the current gold standard in treatment for nerve injuries. A gold standard that requires sacrificing a healthy nerve from another part of the body. With our patented silk-based technology, we’ll deliver an off-the-shelf solution for surgical repair of the nerve. Without the need for long, complicated operations or using expensive donor tissues, Newrotex makes immediate treatment possible for patients who have suffered nerve injuries due to trauma, medical conditions, or surgical treatments.

million

Annual operations for nerve injuries

Newrotex silk-based nerve products address the shortcomings of the solutions currently available.

Most of the world’s 1.5 million annual operations for nerve injuries are treated with autografts requiring a second injury and long surgery times, along with risking donor site morbidity and infection.

All of the major current solutions – autografts, allografts, and hollow tube conduits – are limited when repairing large gaps in nerves. Read Current Approaches for more about these and other shortcomings with current solutions for peripheral nerve repair.

Newrotex silk nerve products not only shorten procedure times, they are low-cost, simple to use, and effective for long-length nerve repairs.

Why Silk is a Good Choice
for Nerve Repair

Over the past few decades, the potential biomedical applications of silk have been gaining interest at an exponential rate.

The versatility created by silk’s chemical structure allows for the production of fibres, gels, scaffolds, films, membranes, and powders. Silk has shown to have excellent cell affinity, and being biocompatible, with the ability to tailor biodegradation, silk is an ideal candidate for biomedical applications.

In terms of nerve repair, luminal silk fibres inside a vein or conduit guide regenerating axons, while the bioabsorbable, permeable tube allows nutrients to support nerve regeneration. Furthermore, silk products can be stored at room temperature, thereby removing the need for expensive cold storage and transportation.

Our Solution

SilkAxons®

Our first product is a 10cm implant made from bundles of luminal spider silk fibres that can be implanted into a vein or inserted into hollow conduits to support nerve re-growth. Pre-clinical studies have show that SilkAxons® support superior axonal regeneration.

Our second product is an off-the-shelf silk-based peripheral nerve conduit pre-filled with enhancing luminal silk fibres, negating the need to use a vein.

The fibres have proven nerve-regenerating properties and clinical trials show them to be comparable or superior to autografts. And with a porous tubular biocompatible sheath designed to encourage vascularisation, we provide a new and better approach to treating patients with peripheral nerve injuries.

Long-term Vision

Newrotex launched a first-in-human clinical trial in Q3 2025 using SilkAxons® to bridge large nerve gaps of up to 10cm (significantly more than current FDA approved devices). This study will generate foundational data for Newrotex’s global clinical strategy. Our goal is to commence a large study this year culminating in an application for market approval in the USA and UK. We are also developing collaborations in which our silk platform technology may lead to further improvements in patient care, such as Schwann cell delivery and spinal cord injury repair.

Autodesk Autocad Raster Design 2021 May 2026

Manufacturers with long product lifecycles often have legacy machine parts designed on paper. Raster Design enables the conversion of these drawings into vector geometry, which can then be imported into Autodesk Inventor or Fusion 360 for 3D modeling or CNC machining.

You receive a 1970s paper sewer map scanned at 300 DPI. It is yellowed, folded, and slightly skewed.

At its core, Raster Design 2021 is a raster-to-vector conversion and image manipulation engine that lives inside the AutoCAD environment. Unlike standard AutoCAD, which struggles with pixel-based images (treating them as bulky external references), Raster Design allows you to treat scanned drawings as editable geometry.

Released as part of the 2021 Autodesk vertical product suite, this version focuses on performance upgrades and seamless interoperability with AutoCAD 2021. It includes tools for:

It is important to note that Raster Design 2021 is not a standalone program. It functions as a plug-in (or "vertical") that loads a new ribbon tab within the standard AutoCAD 2021 interface.

You have an old county map without geospatial data.

Autodesk AutoCAD Raster Design 2021 is an add-on for AutoCAD and AutoCAD-based products that provides raster-to-vector conversion tools, image cleanup and editing capabilities, and advanced scanning workflows. It’s designed for professionals who need to incorporate scanned drawings, aerial imagery, or raster maps into CAD workflows and convert those images into editable vector data.

An engineering firm is tasked with digitizing a 1980s sewer system map. The map contains thick main lines, thin connection pipes, and handwritten text annotations.

Several excellent resources provide details on Autodesk AutoCAD Raster Design 2021, ranging from technical installation guides to functional overviews. Best Comprehensive Guides

Functional Overview: The OSMRE Technical Innovation page provides a clear summary of what the software does, including scanning, geo-referencing, and converting raster images into DWG objects. autodesk autocad raster design 2021

Official Installation Guide: For step-by-step instructions on setting up the toolset, Autodesk's Learning Portal offers an on-demand tutorial for individual installations.

Critical Technical Advisory: This Autodesk Support Article is essential reading; it details a known dependency on older Microsoft Visual C++ Redistributables that can cause the software to crash if uninstalled. Licensing & Updates

Image Cleaning: Access tools to remove "noise" (speckles) and mirror or touch up scanned drawings.

Raster-to-Vector Conversion: Use standard AutoCAD commands on raster regions and primitives to create lines and polylines from scanned files.

GIS Integration: Geo-reference images to display and analyze them within a GIS project framework.

Here’s an interesting, honest, and slightly unconventional review for Autodesk AutoCAD Raster Design 2021:

In civil engineering, surveys often begin with hand-drawn maps or aerial photography. Raster Design allows engineers to "heads-up digitize," where they trace over raster imagery to create vector objects. Crucially, the software can semi-automate the conversion of parcel maps and topographic contours, drastically reducing the manual digitizing time. Manufacturers with long product lifecycles often have legacy

Autodesk AutoCAD Raster Design 2021 is not a glamorous tool. It doesn't render 4K walkthroughs or generate generative design options. But for the working professional tasked with modernizing a basement full of linen blueprints, it is indispensable.

By providing a seamless raster-to-vector pipeline inside the familiar AutoCAD interface, version 2021 offers a stable, high-performance solution for civil engineers, architects, utility mappers, and historians. If you have ever stared at a scanned drawing and wished you could just "pull" a line, this is the tool you need.

To get started:

Still currently used in 2025 by legacy engineering firms, Autodesk AutoCAD Raster Design 2021 remains the quiet hero of digital twin creation.
