Article Abstract

This study fabricated a two-dimensional pneumatic servomechanism-based mask sewing platform. The platform has a simple structure, operates quickly, and is energy-efficient. SOLIDWORKS was used to design the platform, which comprises two rod-less pneumatic cylinders, one auxiliary cylinder, and a fabric-clamping mechanism. These parts are integrated with a sewing machine. The mask sewing platform has two degrees of freedom, as indicated by a mobility analysis of its mechanism. To control the highly nonlinear and time variant pneumatic system, a mathematical model for the pneumatic servo control system was developed and then analyzed in analytical form. An intelligent parameter adjustment feature with a sliding-mode controller was formulated to control the mask sewing platform. An experimental mask sewing platform was then designed and constructed. Finally, a personal computer-based system was developed using MATLAB Simulink for real-time control of the platform. The hybrid and fifth-order paths were successfully implemented in the test rig, and this study's platform was experimentally verified as being capable of automatically producing masks.

Background: Esophagogastric anastomosis is a critical step of esophagectomy. We aimed to develop a novel robotic esophagectomy simulator with high rates of fidelity and educational value for trainee surgeons to advance these skills in a low-risk setting.

Methods: A porcine esophagus-stomach block was secured on a platform resembling the anatomy during an esophagectomy, and a da Vinci Xi (Intuitive Surgical) robotic system was docked above it.

Introduction: The aim of this study was to evaluate the impact of the thoracic robotic approach in a high-volume center regarding procedures and clinical outcomes after 1,000 procedures.

Methods: In a single-center subset of the Epithor® database, a prospective cohort database of French thoracic surgery, we analyzed procedural characteristics and clinical outcomes from February 2014 to April 2023. A surgical technique for lung surgery was conducted with a four-arm closed chest with the port access approach and vascular sewing and knotting were preferred over stapling.

Tracheobronchoplasty for tracheobronchomalacia.

J Vis Surg

Department of Surgery, Lifespan Health System Hospitals, Warren Alpert Medical School, Brown University, Providence, RI, USA.

Tracheobronchoplasty (TBP) consists of splinting of the posterior membranous wall of the central airways with the goal of restoring a normal configuration and preventing excessive collapse in patients with tracheobronchomalacia (TBM). Despite some variation in technique, it consists of sewing a mesh on the posterior membranous wall of the trachea and both main stem bronchi. Traditionally performed through a right posterolateral thoracotomy, it should be reserved for cases of severe TBM.

After the first laparoscopic Roux-en-Y gastric bypass (RYGB) in 1994 by Wittgrove, the introduction of robot-assisted procedures was the next step in the surgical race to reduce invasiveness. This breakthrough allowed us to perform bariatric surgery with less surgical trauma in obese patients with metabolic disorders, producing an exponential increase in procedures performed. This is a retrospective cohort study of a prospective database for patients who underwent RYGB during a 7-year period through two different approaches, laparoscopic and robotic.

The emerging personal healthcare has significantly propelled the development of advanced wearable electronics with novel functions of providing diagnostic information and point-of-care therapies for specific diseases. However, it is still challenging to simultaneously achieve high sensitivity for health biomonitoring and multifunction integration for point-of-care therapies in a one single flexible, lightweight yet robust fiber-based device. Here, a knittable and sewable spandex yarn with conductive nacre-mimetic composite coating has been developed through an alternant dip-coating method employing MXene nanosheets as the "brick" and polydopamine (PDA)/Ni as the "mortar".
