Prototype Design of Robotic Surgical Instrument for Minimally Invasive Robot Surgeryharacteristics of the instrument, it has been designed on the basis of 3-DOF (degrees of freedom) parallel robot mechanism with three identical PSR (Prismatic-Spherical-Revolute)- serial chains. Further, for the forceps grasp and axial rotational motions, it has one additional center leg. With this

Polarizing Beam Splitter Endoscope for Simultaneously Observing Front and Lateral Viewnt and lateral view with single lens system. A polarizing beam splitter (PBS) mounted at its distal end guides the rays from the two FOVs to relay lenses in orthogonal linear polarizations, and the other PBS mounted at its base separates them at eye lens systems. However, the images of the two views

A Laser Steering Endoscope with High Laser Transmission Efficiencynt of twin-to-twin transfusion syndrome. The miniaturized endoscope has an external diameter of 3.5 mm expect for illumination and also improved on the laser transmission efficiency by using a GRIN rod lens as a relay lens. The experiment showed the laser transmission efficiency on the unit of the o

High-Quality Intra-operative Ultrasound Reconstruction Based on Catheter Pathcted by extracting all colored pixels of 2D Doppler images. After center line was computed, cross sections of vessel were sampled and segmented by a modified region growing combining intensity distribution, curvature and area threshold. An ellipse was estimated based on the segmented contour. Finall

Nonlinear Reaction Force Analysis for Characterization of Breast Tissuesast tissue. Then, the measured reaction force is used to estimate the parameters of nonlinear elasticity, which enables the identification of tissue type, such as fat, muscle, mammary gland or tumor. Here, we present the basic concept of our study and preliminary experimental and simulation results
