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.

本项目的目的是开发一种新颖的无线手术摄像系统，以加强和改进单切口腹腔镜手术的手术程序。相机系统可以通过切口或手术器械的自然孔插入体腔，从而消除了腹腔镜相机的专用切口和手术器械的共用切口的需要。该可插入式摄像机的关键创新是设计了半球形驱动单元，该驱动单元由特殊设计的具有不同组织绝缘厚度的磁定子驱动。该设计通过将操纵和导航功能优雅地耦合到半球形驱动单元中，解决了在外科手术期间在体腔内锚定和操纵单个或多个相机系统的挑战。本文的研究成果为一种新型无线腹腔镜摄像机提供了技术和理论基础，该摄像机由一个在体转子和一个离体定子组成，用于单切口腹腔镜手术。创新的设计使腹腔镜相机的精确平移和旋转控制，以及手术场景和手眼协调仪器的关键深度信息的估计。更广泛的影响是通过减少不必要的肌肉割伤和疤痕、失血、住院时间、术后疼痛和恢复时间，为患者带来社会效益。该项目还通过创新的教学和项目设计模块，以及在当地K-12学校和青少年夏令营的示范活动，为本科生和研究生提供教育和推广活动。
