摘要： A system for insufflating a body cavity comprising a swallowable capsule comprising a chamber (11) containing a fluid capable to generate biocompatible gas or vapour by phase transition or chemical reaction, the chamber (11) being formed with at least one orifice (7) for placing it in communication with the outside. The orifice (7) is blocked by a shutter (4, 6; 26) made of magnetic material and there are provided elastic means (8) able to generate an elastic force sufficient to keep said shutter sealingly engaged in the orifice. The system further comprises magnetic actuating means (12; 34) external to the body cavity for generating a magnetic force having strength sufficient to overcome the elastic force of the elastic means disengaging the shutter from the orifice.

摘要： An endoscopic device of the capsular type that is mobile and that can be oriented inside a body cavity, such as the gastrointestinal tract, through a magnetic coupling of the inner magnetic means (1 1 ) inside said body and means for generating a magnetic field (13) external to the patient, and a system for blowing (4, 5, 6) a gaseous fluid and sucking said fluid and/or material present in the body cavity. The device is designed to avoid both the drawbacks of the conventional flexible endoscopes, by reducing the invasiveness and the pain, thus increasing the patient's compliance, and the drawbacks of the capsular endoscopes, by improving their ability to control the movement and keeping the dimensions small. The endoscopic device further allows to carry out local therapeutic and/or surgical treatments of areas of the inspected gastrointestinal tract.

摘要： Robotic platform for mini-invasive surgery comprising robotic arms (4a, 4b) suitable to be placed in the body of a patient, introduced through a single access port, which are an extension of external robotic manipulators (19). The continuity between external (1) and internal (4a, 4b) robotic arms is guaranteed by means of a trans- abdominal magnetic connection (6) between the internal robotic arm integral with the external one. The trans-abdominal magnetic coupling not only guarantees a stable anchoring, but most of all it transfers degrees of freedom to the internal robotic arms, inducing the motion of internal magnets by means of the automatized motion of external magnets. It is also possible to reposition the internal robotic arms without requiring having to additionally perform incisions on the abdomen. Using the external robotic arms allows translating the internal ones on the entire abdomen thus providing a working space not bound to the point of insertion and theoretically unlimited.
摘要翻译：用于微创手术的机器人平台包括适于放置在患者体内的机器人臂（4a，4b），通过作为外部机器人操纵器（19）的延伸部的单个进入口引入。外部（1）和内部（4a，4b）机械手臂之间的连续性通过与外部机械臂整合的内部机械手臂之间的腹部磁性连接（6）来保证。跨腹磁耦合不仅可以保证稳定的锚固，而且最重要的是将内部机械臂的自由度转移，通过外部磁体的自动化运动来引起内部磁体的运动。也可以重新定位内部机器人手臂，而无需另外在腹部进行切口。使用外部机器人手臂允许翻译整个腹部的内部机器人手臂，从而提供不限于插入点的理论上无限制的工作空间。
