THINK Surgical - ROBODOC relived

We all remember ROBODOC, the first real orthopaedic robot performing human procedures. It has an edifying story from the business point of view--preceding its times by far. Now it's back, alive, and received FDA approval. Meet the THINK Surgical system!
"The TSolution OneTM Surgical System combines two exclusive innovations to produce a revolutionary technology. The system consists of TPLANTM, a 3D pre-surgical planning workstation and TCATTM, a computer assisted tool. Together, these two technologies bring an exceptional degree of accuracy to total joint replacements.
During surgery, the TCATTM tool’s patented software allows for CT surface-based registration of the patient’s distinct anatomy. Rather than identify landmarks, you select points in specified regions of the bony surface.
The registration system allows you to mill the bone precisely according to the pre-surgical plan. You control the TCAT tool through a hand-held pendant.
As an additional safety feature, the TCAT tool detects unintended bone motion after fixation and immediately halts the system. If bone motion occurs, the system is designed to recover the registration, thus allowing you to quickly restart and continue the procedure.
Expert surgeons are our partners. Our goal is to make sure their surgical expertise can be fully leveraged and their surgical plans carried out exactly as defined.
The system today is cleared by the FDA for orthopedic surgical procedures for hip in the U.S. The TSolution One core technology has been used in thousands of successful total joint replacements for both hip and knee worldwide."

AVRA Surgical Robotics

 AVRA has published some images about its versatile robot concept.
"AVRA Surgical Robotics is developing a surgical robotic system of a modular construction which offers a portable lightweight and maneuverable robotic solution not available in any system in hospitals today.     We believe our AVRA Surgical Robotics System (ASRS) is the ‘next generation’ in robotically controlled Minimally Invasive Surgical (MIS) Systems in that it will offer a significantly more adaptable platform with modular design, size and compelling cost comparisons (system, service and tools) to current systems.     In addition, we plan to deliver the system at a price point that we believe will open the market to users who are capital constrained in their medical device budgets. Private and public health insurers around the world are becoming more cost-conscious, forcing hospitals to re-evaluate their capital spending plans but strengthening the case for technologies that can reduce the cost and optimize the outcome of surgical procedures. Our approach to robotic surgery does not stop at the robot alone. The AVRA method is to design the operating room specifically for robotic surgery and to coordinate the design of the operating table, lighting systems and surgical instruments as a single intuitive operating environment for the entire surgical team.   AVRA Surgical Robotics' goal is to design and develop a complete minimally invasive surgical robotics system and training platform to improve the economics, efficiency and patient outcome.   Our company's engineering and design laboratories will ensure the highest quality for manufacturing, distribution and support networks worldwide.   We are collaborating with hospitals and highly experienced robotic surgeons throughout the U.S, South America, Europe, India and Asia to develop surgical procedures and instruments specifically for our medical robotic system."
"Designed by the world’s leading robotic surgeons, the AVRA system offers:   
  • Unprecedented flexibility, mobility, freedom of motion and portability provided by its single or multiple arms which enable the benefits of minimally invasive surgery to be applicable in all surgical procedures.   
  • Portability and lighter weight, with a significantly smaller footprint, enabling use in doctors’ offices, group practices, surgical centers or field operations, as well as in hospital operating rooms.   
  • Digitalized solid-state modular robotic arms. Direct drive (no cables and pulleys) permits the exceptional degree of precision and accuracy required in specialties such as neurosurgery.   
  • An extraordinary level of built-in intelligence including sophisticated algorithms, error avoidance, fault tolerance and vital patient information, providing the ability to model, plan and implement customized surgical strategies.   
  • All surgeons access to the knowledge, experience, judgment and techniques of the world’s master robotic surgeons.   
  • An extremely cost-effective alternative to the high cost and severe limitations of current systems which will open robotic-assisted surgery for all procedures in every part of the world."

CT- and MRI-guided computer-assisted needle placement

Minimally invasive biopsies, drainages and therapies in the soft tissue organs of the thorax and abdomen are typically performed through a needle, which is inserted percutaneously to reach the  target area. The conventional workflow for needle placement employs an iterative freehand  technique. This article provides an overview of needle-placement systems developed to improve this method.
An overview of systems for needle placement was assembled, including those found in scientific publications and patents, as well as those that are commercially available. The systems are categorized by function and tabulated.
Over 40 systems were identified, ranging from simple passive aids to fully actuated robots.
The overview shows a wide variety of developed systems with growing complexity. However, given that only a few systems have reached commercial availability, it is clear that the technical community is struggling to develop solutions that are adopted clinically.
