Non-invasive surgery through the skull - 0 views

    "The surgery helmet integrates magnetic resonance imaging (MRI) and high intensity focused ultrasound to provide a non-invasive, image-guided personalized treatment of brain disorders through an intact skull with no ionizing radiation."

Robot's Gentle Touch Aids Delicate Cancer Surgery - 0 views

  • Surgeons have developed new minimally invasive surgery (MIS) techniques and instruments so that procedures that would previously have required a large incision can now be performed through a tiny 10mm cut.
  • University of Western Ontario and Canadian Surgical Technologies and Advanced Robotics (CSTAR) in London, Ontario
  • The researchers used a torque sensor to measure the force of the palpations.
  • ...2 more annotations...
  • Using tactile MIS sensing instruments under robotic control reduces the maximum force applied to the tissue by over 35% compared to a human controlling the same instrument. Accuracy in detecting the tumours was also far greater with the robot - between 59 and 90% depending on the robot control method used for palpation.
  • If developed further, the authors suggest that this type of instrument would particularly benefit surgeons performing lung tumour resection, where tissue often shifts significantly.

      that's why a sensor is required !

      Right man! It's interesting to see that these instruments are also needed to almost all robot-assisted surgery procedures. So it's more than just brain manual surgery.

A Robust Uniaxial Force Sensor for Minimally Invasive Surgery - 0 views

  • miniature uniaxial force sensor for use within a beating heart during mitral valve annuloplasty
  • provides a hollow core to pass instrumentation
  • Fiber optic transduction eliminates electrical circuitry within the heart, and acetal components minimize ultrasound-imaging artifacts
  • ...4 more annotations...
  • 0–4-N force range
  • errors of 0.13 N (<3.2%)
  • MINIMALLY invasive surgery (MIS)
  • surgeons lose the critical sense of touch during MIS because instruments are passed through ports that mask the surgeon's feel of the internal operating environment.

Stretchable electronics to simplify heart surgery? - 0 views

  • Currently this catheter method requires the use of three different devices, which are inserted into the heart in succession: one to map the heart's signals and detect the problem area, a second to control positions of therapeutic actuators and their contact with the epicardium, and a third to burn the tissue away.
  • The device is designed to deliver critical, high quality information - such as temperature, mechanical force, and blood flow - to the surgeon in real time.

Nanotubes make 'exceptional' strain sensor - 0 views

  • Affixed to the chest as a respiration monitor, the team suggest it might help prevent sudden infant death syndrome (SIDS) but Hata's favourite application is the "data glove", which senses the movement of each finger. The group's glove sensed the motions of typing, but they say a version could be used to guide robots which perform surgery.  Hata also has more fun applications in mind, such as game controllers and virtual reality systems.
