Transferable Deep Reinforcement Learning With Edge‐Contour‐Depth Fusion for Autonomous Wireless Capsule Endoscopy Navigation

Advanced Science, EarlyView.
This study presents an anatomical landmark‐guided DRL framework for autonomous wireless capsule endoscopy navigation. Using a lightweight edge‐contour‐depth fusion module, it achieves over 97% coverage across diverse gastric anatomies. To ensure reliability, a two‐stage sim‐to‐real pipeline with an adaptive dynamic programming controller mitigates ...

Bronchoscopy Robot with Enhanced Flexibility and Stability via Multi‐Segment Variable Stiffness Catheter

Advanced Intelligent Systems, EarlyView.
This work presents a magnetic bronchoscopy robot with a novel multi‐segment variable stiffness catheter. This catheter can not only move flexibly in the narrow bronchi but also harden according to the need to provide support. Combined with remote wireless magnetic field drive, it provides a more precise and effective solution for biopsy of deep lung ...

Intra‐articular Proximal Biceps Tenotomy With Extra‐articular Transfer: A Technique to Repair Full‐thickness Rotator Cuff Tears

Arthroscopy Techniques, EarlyView.
Abstract The long head of the biceps tendon (LHBT), as a tendinous structure adjacent to the rotator cuff, can be easily used to repair the rotator cuff. Currently, there are many different surgical procedures for the LHBT. Direct severance of the LHBT is simple but may result in pain and deformity, and fixation of the LHBT wastes the tendinous tissue ...

Additional lateral meniscus centralization reduces residual anterolateral rotatory instability after anterior cruciate ligament reconstruction and lateral meniscus repair

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study aimed to examine the effects of lateral meniscus (LM) centralization on anterolateral rotational stability in patients with anterior cruciate ligament (ACL) and LM injuries. The hypothesis was that performing LM repair and centralization on knees with LM lesions would control anterolateral rotatory instability (ALRI ...

Endoscopic‐Assisted Transcervical Excision of Second Branchial Cleft Anomalies in Young Children

The Laryngoscope, EarlyView.
We describe an endoscopic‐assisted transcervical technique for excision of second branchial cleft anomalies in young children. In three cases (ages 2–8), this approach allowed safe identification and ligation of the tracts while providing improved visualization and allowing smaller incisions.
