The invention relates to a surgical staple having two movable arms (1, 2) connected by a transverse connection area (3). Each one of said arms (1, 2) has a pinching area (15, 25) and a fastening end (11, 21) and is characterised in that said transverse connection area (3) is deformable to allow said movable arms (1, 2) to be moved together by bending around the axis of said transverse connection area (3).
摘要:
System and methods for an automatic multimodal real-time tracking of moving instruments for image plane alignment inside a MRI scanner. The used system (1) is suitable for tracking a moving marker, stand alone or fixed on an instrument, a holding system or a body of a subject. It comprises: • - an MRI scanner (2), • - an MRI multi-plane pulse sequence generating means allowing to interactively modify the position and orientation of one or several image planes in real-time, • - one or several external optical sensors (3) with high frame rate, preferably a RGB-D sensor or an other similar camera system like a stereovision systems, • - a multimodal marker (4) comprising at least one MR visible feature and one visual feature able to be tracked by both the MRI scanner (2) and the at least one external optical sensor (3), • - a computer (5) able to process in real-time the images from both MRI and optical sensor in order to fuse the detected marker position and orientation or pose from both modalities, and predict the next image plane position and orientation based on the estimated motion of the moving marker (4), in order to automatically track said marker and automatically align the image planes with respect to the marker, or to a hoding system or body location it is fixed on.
摘要:
This invention concerns a method for automatically detecting a clinically relevant leak and/or inadequate closure following a medical procedure, in a hollow organ (2) residing in the interior volume (4') of a body cavity (4). Wherein said test method comprises the steps of: injecting, via adapted injection means (3) a specific test gas or a gas mixture containing at least one test gas, into said organ(s) (2), analyzing the gas mixture and measuring the concentration of test gas in the interior volume (4') of the body cavity (4) via adapted detection means (5) and at least during a measurement window, evaluating the likelihood of the presence of a leak and its degree of severity, by comparing stored data and realtime data with each other, said test method being characterized in that the pressure difference between the interior of the hollow organ(s) (2) and the interior volume (4') of the body cavity (4) is controlled or mastered at least at a given moment during at least one measurement window, and preferably maintained constant during said window.
