A Semi-spherical Magnetic Driven Wireless Camera for Single Incision Laparoscopic Surgery

本项目的目标是开发一种新型的无线手术摄像系统，以增强和改进单切口腹腔镜手术的手术过程。摄像机系统可以通过手术器械的切口或自然开口插入体腔，从而消除了对腹腔镜摄像机专用切口的需要，也消除了手术器械共用切口的需要。可插入式相机的关键创新是设计了一个半球形驱动单元，由一个特殊设计的磁定子外部驱动，具有不同厚度的组织绝缘。该设计通过巧妙地将操作和导航功能耦合到半球形驱动单元中，解决了在外科手术中在体腔内锚定和操纵单个或多个摄像头系统的挑战。智能优势是由活体转子和体外定子组成的新型无线腹腔镜摄像头用于单切口腹腔镜手术的技术和理论基础。创新的设计能够精确地控制腹腔镜摄像机的平移和旋转，并估计手术场景和手眼协调器械的关键深度信息。更广泛的影响是通过减少不必要的肌肉割伤和疤痕、出血、住院时间、术后疼痛和恢复时间为患者带来更广泛的社会效益。该项目还通过创新的教学和项目设计模块向本科生和研究生提供教育和外联活动，以及在当地K-12学校和青年夏令营开展示范活动。

The objective of this program is to develop a novel wireless surgical camera system to enhance and improve surgical procedures for single incision laparoscopic surgery. The camera system can be inserted into a body cavity via an incision or a natural orifice for the operation instruments, which eliminates the need for dedicated incisions for laparoscopic cameras and the shared use of an incision for surgical instruments. The key innovation of the insertable camera is the design of a semi-spherical driving unit driven externally by a specially designed magnetic stator with varying thickness of tissue insulation. The design addresses the challenges in anchoring and manipulating single or multiple camera systems inside body cavities during surgical operations by elegantly coupling manipulation and navigation functions into the semi-spherical driving unit.The intellectual merit is the technological and theoretical bases for a new class of wireless laparoscopic cameras that consist of an in vivo rotor and an ex vivo stator for single incision laparoscopic surgery. The innovative design enables precise translational and rotational control of laparoscopic cameras, and the estimation of critical depth information of the surgical scene and instruments for hand eye coordination.The broader impacts are the societal benefits to patients by reducing unnecessary muscle cuts and scars, blood loss, hospital stay duration, post-operative pain, and recovery time. This project also provides education and outreach activities to undergraduate and graduate students by innovative teaching and project design modules, and demonstration activities at local K-12 schools and youth summer camps.
