Using Smartphones for Clinical Assessment in Cervical Spondylotic Myelopathy a Feasibility Study
(The American Society of Mechanical Engineers (ASME), 2021)Degenerative cervical myelopathy (DCM) is characterized by a progressive deterioration in spinal cord function. Its evaluation requires subjective clinical examination with wide interobserver variability. Objective ... -
Design of Low-Cost Endoscope Based on Novel Wire-Driven Rotary Valve and Water-Jet Mechanism
(The American Society of Mechanical Engineers (ASME), 2021)To improve the prevalence of screening for gastric cancer in low-income areas, a low-cost endoscope based on a novel wire-driven rotary valve and water-jet mechanism is proposed. The primary component of this endoscope is ... -
Design of a Surgical Pen-Type Probe for Real-Time Indocyanine Green Fluorescence Emission Diagnosis
(The American Society of Mechanical Engineers (ASME), 2021)The advantage of handheld type surgical microscope is that the size of the probe is small and light, and that both the working distance (15–30 cm) and field of view (30 deg) can be adjusted. The shortness working distance ... -
A New Test Method for In Vitro Evaluation of Pedicle Screw Loosening Potential
(The American Society of Mechanical Engineers (ASME), 2021)This paper proposes a new test method based on the toggle effect under transverse loads (cranial–caudal) to investigate the loosening potential of pedicle screw designs. A three-step in vitro testing procedure was developed ... -
Characterization and Validation of Fatigue Strains for Superelastic Nitinol Using Digital Image Correlation
(The American Society of Mechanical Engineers (ASME), 2021)Fatigue is a major challenge encountered in cardiovascular implant design. While the properly heat-treated Nitinol can exhibit up to 6–7% recoverable strains allowing for minimally invasive transcatheter delivery of ... -
Apparatus for In Vivo Knee Laxity Assessment Using High-Speed Stereo Radiography
(The American Society of Mechanical Engineers (ASME), 2021)Computational modeling is of growing importance in orthopedics and biomechanics as a tool to understand differences in pathology and predict outcomes from surgical interventions. However, the computational models of the ... -
Functional Evaluation of a Personalized Orthosis for Knee Osteoarthritis: A Motion Capture Analysis
(The American Society of Mechanical Engineers (ASME), 2021)Orthotic treatments for knee osteoarthritis (OA) typically rely on simple mechanisms such as three-point bending straps and single-pin hinges. These commonly prescribed braces cannot treat bicompartmental knee OA, do not ... -
Preliminary Evaluation of Hydraulic Needle Delivery System for Magnetic Resonance Imaging-Guided Prostate Biopsy Procedures
(The American Society of Mechanical Engineers (ASME), 2021)In clinical routine, the prostate biopsy procedure is performed with the guidance of transrectal ultrasound (TRUS) imaging to diagnose prostate cancer. However, the TRUS-guided prostate biopsy brings reliability concerns ... -
A New Medical Device Modeling Framework for Predicting the Performance of Indwelling Continence Care Devices and Improving Patient Care
(The American Society of Mechanical Engineers (ASME), 2021)A computational model of the human torso has been developed to study the stability of implanted leads that are part of a sacral nerve stimulation system. The model was built using presegmented anatomies that were themselves ... -
Literature Review on Endoscopic Robotic Systems in Ear and Sinus Surgery
(The American Society of Mechanical Engineers (ASME), 2021)In otolaryngologic surgery, endoscopy is increasingly used to provide a better view of hard-to-reach areas and to promote minimally invasive surgery. However, the need to manipulate the endoscope limits the surgeon's ability ... -
A Systematic Review of Compliant Mechanisms as Orthopedic Implants
(The American Society of Mechanical Engineers (ASME), 2021)Currently available motion-preserving orthopedic implants offer many advantages but have several limitations to their use, including short device lifetime, high part count, loss of natural kinematics, and wear-induced ... -
Design and Performance Testing of a Novel In Vivo Laparoscope Lens Cleaning Device
(The American Society of Mechanical Engineers (ASME), 2021)A common tool for diagnosis and treatment of gastrointestinal, gynecologic, and other anatomical pathologies is a form of minimally invasive surgery known as laparoscopy. Roughly 4 × 106 laparoscopic surgeries are performed ... -
A Low-Cost Visual Grasp Aid for Neuropathy Patients Using Flexible Three-Dimensional Printed Tactile Sensors
(The American Society of Mechanical Engineers (ASME), 2021)Neuropathy is a nerve-damaging disease that causes those affected to lose feeling in their otherwise functional limbs. It can cause permanent numbing to the peripheral limb of a patient such as a hand or foot. In this ... -
A Vibratory, Subresonant Diagnostic Device to Measure Dental Implant Stability Via Angular Stiffness
(The American Society of Mechanical Engineers (ASME), 2021)Stability of a dental implant reflects quality of osseointegration between the implant and its surrounding bone. While many methods have been proposed to characterize implant stability, angular stiffness at the neck of the ... -
Monocular Vision-Based Retinal Membrane Peeling With a Handheld Robot
