Design, Fabrication, and Testing of a Flexible Three-Dimensional Printed Percutaneous Needle With Embedded Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Percutaneous needle-based procedures have replaced open surgeries in cancer treatments to perform the tasks with minimal invasiveness to the tissue. Precise placement of the needle at target positions in cancer diagnostic ...
Finite Element Studies of Needle–Tissue Interactions for Percutaneous Procedures1
Publisher: The American Society of Mechanical Engineers (ASME)
Shape Memory Alloy Actuators in an Active Needle—Modeling, Precise Assembly, and Performance Evaluation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Today, several medical diagnosis and therapeutic cancer interventions are performed using needles via percutaneous surgical procedures. The success of these procedures highly depends on accurate placement of the needle tip ...
A Model to Predict Deflection of an Active Tendon-Driven Notched Needle Inside Soft Tissue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The last decade has witnessed major progress in the field of minimally invasive and robotic-assisted surgeries. Needle insertion, a minimally invasive technique, has proven its efficacy in procedures such as brachytherapy, ...
Feasibility of Shape Memory Alloy Wire Actuation for an Active Steerable Cannula
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Needle insertion is used in many diagnostic and therapeutic percutaneous medical procedures such as brachytherapy, thermal ablations, and breast biopsy. Insufficient accuracy using conventional surgical cannulas motivated ...
