Design and Evaluation of a Novel Rotatable One-Element Snake Bone for NOTES
(The American Society of Mechanical Engineers (ASME), 2018)The distal head of the natural orifice transluminal endoscopic surgery (NOTES) platform commonly uses the structure of a snake bone, which cannot rotate, and the manufacturing is often time-consuming. A novel rotatable, ... -
Optimizing Design With Extensive Simulation Data: A Case Study of Designing a Vacuum-Assisted Biopsy Tool
(The American Society of Mechanical Engineers (ASME), 2018)Design by Dragging (DBD) [1] is a virtual design tool, which displays three-dimensional (3D) visualizations of many simulation results obtained by sampling a large design space and ties this visual display together with a ... -
Magnetic Chest Tube Positioning System
(The American Society of Mechanical Engineers (ASME), 2018)Tube thoracostomy (TT) insertion can serve as a life-saving adjunct for thoracic trauma. Unfortunately, suboptimal positioning using the open, standard of care technique is associated with complications resulting in impaired ... -
Development and Feasibility of a Robotic Laparoscopic Clipping Tool for Wound Closure and Anastomosis
(The American Society of Mechanical Engineers (ASME), 2018)This paper reports the design, development, and initial evaluation of a robotic laparoscopic clipping tool for single manipulator wound closure and anastomosis (tubular reconnection). The tool deploys biodegradable clips ... -
A Novel Graft Fixation Technique for Anterior Cruciate Ligament Reconstruction Using Hamstring Tendon Grafts
(The American Society of Mechanical Engineers (ASME), 2018)This study evaluated the biomechanical efficacy of single-tunnel double-bundle anterior cruciate ligament (ACL) reconstruction technique. The graft construct is achieved using a novel fixation device that splits an ACL ... -
Electrokinetic Behavior of Heat-Treated Mycobacterium Bacillus Calmette-Guérin Cells
(The American Society of Mechanical Engineers (ASME), 2018)Dielectrophoresis (DEP) can be an effective tool to show the physiological change of bacterial cells. The behavior of bacterial cells under an electric field is complicated due to the combined effects of electrokinetic ... -
Advances in Diagnostic Methods for Zika Virus Infection
(The American Society of Mechanical Engineers (ASME), 2018)The Zika virus (ZIKV) is one of the most infamous mosquito-borne flavivirus on recent memory due to its potential association with high mortality rates in fetuses, microcephaly and neurological impairments in neonates, and ... -
Optimization of an Endoscopic Radiofrequency Ablation Electrode
(The American Society of Mechanical Engineers (ASME), 2018)Radiofrequency ablation (RFA) is an increasingly used, minimally invasive, cancer treatment modality for patients who are unwilling or unable to undergo a major resective surgery. There is a need for RFA electrodes that ... -
Development of an Alveolar Transbronchial Catheter for Concurrent Fiber Optics-Based Imaging and Fluid Delivery
(The American Society of Mechanical Engineers (ASME), 2018)Optical molecular imaging is an emerging field, and high-resolution optical imaging of the distal lung parenchyma has been made possible with the advent of clinically approved fiber-based imaging modalities. However, ... -
Effect of the Bowl Structure in an Automated Cell-Isolation Device on Stromal Vascular Fraction's Isolation Yield
(The American Society of Mechanical Engineers (ASME), 2018)The enzymatic digestion of lipoaspirate is used to isolate the heterogeneous stromal vascular fraction (SVF) that contains the adipose-derived stromal cells (ASCs). Several automated SVF isolation systems are used to operate ... -
New Adjustable Unloader Knee Brace and Its Effectiveness
(The American Society of Mechanical Engineers (ASME), 2018)Unloader knee braces are prescribed for patients with unicompartmental osteoarthritis of the knee. These braces aim to reduce pain in patients by applying a coronal moment to the knee to unload the symptomatic knee ... -
Creating a Small Anchor to Eliminate Large Knots in Mesh and Tape Suture
(The American Society of Mechanical Engineers (ASME), 2018)Wide mesh or tape sutures are used to close high-tension wounds such as in hernia or tendon repair. However, wide sutures produce large knots that are susceptible to increased palpability, infection, and foreign body ... -
Estimation of the Two Degrees-of-Freedom Time-Varying Impedance of the Human Ankle
(The American Society of Mechanical Engineers (ASME), 2018)An understanding of the time-varying mechanical impedance of the ankle during walking is fundamental in the design of active ankle-foot prostheses and lower extremity rehabilitation devices. This paper describes the ... -
Endoscopic Closure of Large Defects With a Novel Clipping Device and a 4S-Modified Roeder Slipknot
(The American Society of Mechanical Engineers (ASME), 2018)Endoscopic closure is an essential procedure in gastrointestinal (GI) surgery, but currently it is difficult to close large defects endoscopically because of the lack of an appropriate device. Previously, we developed an ... -
Vibration-Assisted Slicing of Soft Tissue for Biopsy Procedures
(The American Society of Mechanical Engineers (ASME), 2018)Skin cancer represents one of the most common forms of cancer in the U.S. This and other skin disorders can be effectively diagnosed by performing a punch biopsy to obtain full-thickness skin specimens. Their quality depends ... -
A Novel Macroscale Acoustic Device for Blood Filtration
(The American Society of Mechanical Engineers (ASME), 2018)Retransfusion of a patient's own shed blood during cardiac surgery is attractive since it reduces the need for allogeneic transfusion, minimizes cost, and decreases transfusion related morbidity. Evidence suggests that ... -
Engineering Evaluation of the Performance of an Automatic Peripheral Oxygen Controller Using a Neonatal Respiratory Model
(The American Society of Mechanical Engineers (ASME), 2018)Premature infants often require respiratory support with a varying concentration of the fraction of inspired oxygen FiO2 to keep the arterial oxygen saturation typically measured using a peripheral sensor (SpO2) within the ... -
