Electro-Hydraulic Surgical Tools Small Enough to Widen Scope of Minimally Invasive Surgery (VIDEO)

This has been a limitation that has made it impossible to perform certain operations in a minimally invasive fashion. To overcome this, a team from the Department of Mechanical and Materials Engineering, University of Nebraska Lincoln and Center for Advanced Surgical Technology (CAST) at University of Nebraska Medical Center has developed a tiny multi-instrument robotic surgical tool that can be delivered to a challenging surgical site using a flexible snake.

The electro-hydraulic manipulator, reported on in the Journal of Medical Devices, has four instruments within its body, each of which can be pulled out and used independently. In practice, multiple of these manipulators can be attached to the end of a flexible snake that would deliver the instruments into the body through a natural orifice or an incision. Here’s a video showing off the impressive capabilities of the technology:

GE’s Discovery IGS 740 Angiography System Cleared by FDA (VIDEO)

GE's Discovery IGS 740 Angiography System Cleared by FDA (VIDEO)

GE Healthcare received FDA clearance for its Discovery IGS 740, a mobile angiography designed for hybrid operating rooms. The system rides on floor and can position itself in just about any state, moving to-and-fro the patient as may be necessary. A spinning laser atop the imaging unit keeps an eye on markers placed along the surgical suite’s ceiling, which provides accurate real-time position information to the device and permits it to return to the exact same state it took previously.

The system features a large 41″ x 41″ (104 cm x 104 cm) detector, bedside controls, and imaging capabilities such as 3D visualization, live 3D guidance, and needle tracking.

GE’s Revolution CT, An All Purpose High-End Scanner FDA Cleared

GE's Revolution CT, An All Purpose High-End Scanner FDA Cleared

GE has received FDA clearance and is introducing its Revolution CT scanner to the U.S. market. The device can be used for just about all clinical applications, and features capabilities such as whole heart scans even in patients with a high heart rate, low-dose whole organ (16 cm) scans using dynamic acquisition modes, and whole brain perfusion and dynamic CT angiography at low dose for stroke assessment.

The scanner is able to do some of the things that it does thanks to a high speed gantry that can do revolutions within .28 seconds and is ready to spin as fast as .2 seconds per revolution for future applications.

Intuitive’s New da Vinci Xi Robotic Surgical System Unveiled (VIDEO)

Intuitive's New da Vinci Xi Robotic Surgical System Unveiled (VIDEO)

Intuitive Surgical, the behemoth of robotic-assisted surgery that has in many ways revolutionized minimally invasive surgery, just received FDA clearance for its new da Vinci Xi system. The company has invested considerable effort to expanding the capabilities of the da Vinci, hopefully opening new applications for the technology in thoracic, cardiac, and other surgical areas.

“Our goal is to develop technology that enhances surgical performance,” said Gary Guthart, Intuitive Surgical President and Chief Executive Officer in the announcement. “The da Vinci Xi System’s new overhead architecture means that multi-quadrant surgery can be performed without repositioning the system, an innovation long sought by surgeons who perform complex procedures. We strive to provide the most advanced, least invasive option for surgery, and we are working hard to make minimally invasive surgery the standard of care.”

Telelap ALF-X Endoscopic Robotic Surgical System

Telelap ALF-X Endoscopic Robotic Surgical System

Intuitive Surgical is the dominant player in robotic surgery, having developed the now famous da Vinci System that turned traditional endoscopy into a futuristic endeavor. Now we learn of a system being developed by SOFAR, an Italian pharmaceutical firm, that looks set to compete with the da Vinci.

The Telelap ALF-X features haptic feedback, allowing the surgeon to indirectly “feel” the tissues that are being manipulated. This can lead to improved safety and allow certain maneuvers to be performed with greater confidence. The system also tracks the surgeon’s eye movements, positioning the camera so the field of view is centered where the eyes are looking. The system is highly adjustable for an optimal ergonomic experience. Here are a few video previews of the system in action:

Medrobotics’ New Flex System for Snake-Like Surgical Endoscopy Cleared in Europe

Medrobotics' New Flex System for Snake-Like Surgical Endoscopy Cleared in Europe

Surgical endoscopy has been hailed as the route to an end to open surgical procedures, but many relatively simple operations still have to be done with a scalpel. Enter the Flex System from Medrobotics (Raynham, Massachusetts), the first surgical endoscopy device with snake-like abilities that allow it to reach places that straight instruments simply can’t.

The technology behind the Flex was originally developed at the Carnegie Mellon Robotics Lab and developed further by Farm, a medical device product development firm. It involves flexible concentric components that can be made to be stiff or go limp as necessary, together acting like a snake that can be positioned around obstacles. The tip of the snake can accept a variety of instruments through the multiple channels within the endoscope, and also hosts a forward looking high definition video camera.

Evoked Potential Assessment Device Prevents Arms and Legs from Falling Asleep During Surgery

Evoked Potential Assessment Device Prevents Arms and Legs from Falling Asleep During Surgery

All of us have fallen asleep on an arm or sat too long on a twisted leg only to get up and feel like the limb itself has fallen asleep. Nerves can get stretched and compressed, and blood vessels squeezed, and, if a person’s position is not corrected soon enough, it can lead to permanent tissue damage, compartment syndrome and such . This scenario can happen during surgery, but since the patient is anesthetized and can’t feel, the situation usually goes undetected and can lead to significant damage. A new product from SafeOp, a company out of Hunt Valley, Maryland has received FDA clearance for “positioning effect” monitoring without having a dedicated nneurophysiological monitoring team.

The Evoked Potential Assessment Device (EPAD) uses SSEPs (somatosensory evoked potentials) to detect abnormal nerve signaling that is indicative of poor patient positioning. The output of the device is sent wirelessly via Bluetooth to a tablet that can be hung beside the patient to allow a live view of the positioning effect so that clinicians can move the patient and prevent intra-op damage.

CareFusion’s V. Mueller New Line of Bipolar Electrosurgical Tools

CareFusion's V. Mueller New Line of Bipolar Electrosurgical Tools

CareFusion is releasing a new line of customized bipolar electrosurgical devices that include a variety of forceps and scissors. The V. Mueller branded tools can be selected by surgeons to be non-stick, be made of titanium, and have irrigation capabilities.

The bipolar energy delivery to the instrument through a single cord allows for less damage to nearby  tissue while preventing cords from tangling around each other and allowing surgeons easier access around the surgical site.
