Thoracic drainage is a common procedure to drain fluid, blood, or air from the pleural cavity. Some attempts to develop approaches to new thoracic drainage systems have been made; however, a simple tube is often currently used. The existing drain presupposes that it is placed correctly and that the tip does not require moving after insertion into the thoracic cavity. However, in some cases, the drain is not correctly placed and reinsertion of an additional drain is required, resulting in significant invasiveness to the patient. Therefore, a more effective drainage system is needed. This study aimed to develop and assess a new thoracic drain via a collaboration between medical and engineering personnel. We developed the concept of a controllable drain system using magnetic actuation. A dry laboratory trial and accompanying questionnaire assessment were performed by a group of thoracic and general surgeons. Objective mechanical measurements were obtained. Porcine experiments were also carried out. In a dry laboratory trial, use of the controllable drain required significantly less time than that required by replacing the drain. The average satisfaction score of the new drainage system was 4.07 out of 5, indicating that most of the research participants were satisfied with the quality of the drain with a magnetic actuation. During the porcine experiment, the transfer of the tip of the drain was possible inside the thoracic cavity and abdominal cavity. This controllable thoracic drain could reduce the invasiveness for patients requiring thoracic or abdominal cavity drainage.
胸腔引流是一种从胸腔排出液体、血液或气体的常见操作。人们已尝试开发新的胸腔引流系统；然而，目前通常仍使用简单的导管。现有的引流管假定其放置正确且插入胸腔后尖端无需移动。然而，在某些情况下，引流管放置不正确，需要重新插入额外的引流管，这对患者造成了显著的侵袭性。因此，需要一种更有效的引流系统。本研究旨在通过医学和工程人员的合作开发并评估一种新型胸腔引流管。我们利用磁驱动开发了可控引流系统的概念。一组胸外科和普通外科医生进行了干式实验室试验及伴随的问卷调查评估。获得了客观的力学测量结果。还进行了猪实验。在干式实验室试验中，使用可控引流管所需的时间明显少于更换引流管所需的时间。新引流系统的平均满意度得分为4.07（满分5分），这表明大多数研究参与者对磁驱动引流管的质量感到满意。在猪实验中，引流管尖端在胸腔和腹腔内能够移动。这种可控胸腔引流管可以降低需要胸腔或腹腔引流患者的侵袭性。
