The robotic device can accurately steer needles and catheters into tiny blood vessels with minimal supervision. When nearby blood vessels are inaccessible, more invasive approaches such as central venous or arterial access are often required. Bleeding complications can arise when major adjacent arteries, nerves or internal organs are punctured, and the risk of complication rises significantly with multiple attempts. In these groups, the first-stick accuracy rate is below 50 percent and at least five attempts are often needed, leading to delays in treatment. The timeliness of procedures can be critical, but gaining access to blood vessels in many people can be quite challenging.įailures occur in an estimated 20 percent of procedures, and difficulties increase in people with small, twisted, rolling or collapsed blood vessels, which are common in pediatric, elderly, chronically ill and trauma patients, the study says. They include drawing blood, administering fluids and medications, introducing devices such as stents and monitoring health. Getting access to veins, arteries and other blood vessels is a critical first step in many diagnostic and therapeutic procedures.

This would allow health care professionals to focus more on other critical aspects of medical care and enable emergency medical providers to bring advanced interventions and resuscitation efforts to remote and resource-limited areas. Medical robots could reduce injuries and improve the efficiency and outcomes of procedures, as well as carry out tasks with minimal supervision when resources are limited. Their most recent research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on some complex medical tasks.

Digital artists, using AxiDraw to plot their artwork.As a "handwriting" machine for various purposes.As a signature machine for checks, diplomas, headshots, etc.In order to keep the weight light where it matters, the moving Y-axis of the AxiDraw SE/A3 uses the same stiff and light custom aluminum extrusion found on the AxiDraw V3/A3.īeyond this, the central beam and X-axis of the AxiDraw SE/A3 feature an all-new geometry for the rolling wheels, which provides more stable and uniform motion along the axis. This design adds mass exactly where you want it: to the non-moving base that forms the X-axis of the machine. This heavy, rigid structure - it's a solid block of metal! - provides dramatically better straightness and stiffness, even compared to the already-stiff AxiDraw V3/A3. In place of the central extrusion that makes up the body of that machine, the AxiDraw SE/A3 has a central beam that is CNC machined from a solid billet of 6061-T6 aluminum, and then anodized to a sleek black finish. It has the same extended plotting area as the AxiDraw V3/A3. The AxiDraw SE/A3 Personal Writing & Drawing Robot is a simple, modern, precise, and versatile pen plotter.
