#1
Jie Cao, Canhui Lu, Jian Zhuang, Manxiao Liu, Xinxing Zhang, Yanmei Yu, Qingchuan Tao
Despite its widespread use in signal collection, flexible sensor has been rarely used in human-machine interaction due to its indistinguishable signal, poor reliability and stability when suffered from unavoidable scratches and/or mechanical cuts. Here, we demonstrate a highly sensitive and self-healing sensor enabled by multiple hydrogen bonding network and nanostructured conductive network. The nanostructured supramolecular sensor displays extremely fast (~15 s) and repeatable self-healing ability with high healing efficiency (93% after the 3rd healing process)...

Robotic surgery has become the standard of care for many procedures outside of otolaryngology and now is gaining momentum within our specialty. The da Vinci (Intuitive Surgical, Sunnyvale, CA) robot has several advantages to human hands, including removal of tremor and better access to lesions because of increased degree of movement of the articulated instruments. The glottis has rarely been addressed using robotic surgery because access was previously thought to be difficult because of the limitations of currently used retractors, which include poor base of tongue and oral commissure retraction resulting in lack of exposure of the glottis in many patients and lack of space for the robotic instruments to occupy...

T J Gal, Brian Hixon, Paul Zhang
This case report describes the use of trans-oral robotic surgery (TORS) for the excision of a combined laryngocele. Mixed or combined laryngoceles extend from the supraglottic larynx through the thyrohyoid membrane into the neck. Surgical excision for these benign lesions often requires combined external (transcervical) and internal (transoral endoscopic) approaches which carry significant morbidity. We present the case of a 37-year-old male who was diagnosed with a large laryngopyocele and was subsequently managed with a transoral excision using the da Vinci Si surgical robot system...
