Tactile feedback is completely lost in laparoscopic surgery, which would provide information about tissue compliance, texture, structural features, and foreign bodies. We developed a system with artificial tactile feedback for laparoscopic surgery that consists of a telemetric tactile laparoscopic grasper, a remote PC with customized software, and a commercial video-mixer. A standard, nonsensorized laparoscopic grasper was customized to allow the integration of a tactile sensor and its electronics. The tactile sensor and the electronics module were designed to be detachable from the instrument. These parts are lightweight and wireless, thus not impeding the use of the device as surgical instrument. The remaining system components used to generate visualization of the tactile data do not influence the workflow in the operating room. The overall system design of the described instrumentation allows for easy implementation in an operating room environment. The fabrication of the tactile sensor is relatively easy and the production costs are low. With this telemetric laparoscopic grasper instrument, systematic preclinical studies can be performed in which surgeons execute surgical tasks that are derived from clinical reality. The experience gained from these investigations could then be used to define the requirements for any further development of artificial tactile feedback systems.
在腹腔镜手术中，触觉反馈完全丧失，而触觉反馈本可提供有关组织顺应性、质地、结构特征和异物的信息。我们开发了一种用于腹腔镜手术的具有人工触觉反馈的系统，该系统由一个遥测触觉腹腔镜抓钳、一台装有定制软件的远程个人计算机和一台商用视频混合器组成。对一个标准的、未配备传感器的腹腔镜抓钳进行了定制，以便能够集成触觉传感器及其电子元件。触觉传感器和电子模块设计为可从器械上拆卸。这些部件重量轻且无线，因此不会妨碍该设备作为手术器械的使用。用于生成触觉数据可视化的其余系统组件不会影响手术室的工作流程。所描述器械的整体系统设计便于在手术室环境中实施。触觉传感器的制造相对容易，生产成本较低。使用这种遥测腹腔镜抓钳器械，可以进行系统的临床前研究，让外科医生执行源自临床实际的手术任务。从这些研究中获得的经验随后可用于确定人工触觉反馈系统进一步发展的要求。
