Abstract: The present invention discloses a steerable guidewire and a method for manufacturing the same, and a steerable catheter and a method for manufacturing the same. According to an aspect of the present invention, a steerable guidewire, which is inserted into a catheter and guides the catheter to a desired blood vessel, may include: a steerable tip part that can be bent in at least two stages due to a stimulus from the outside and that is steered in a predetermined direction; and a non-steerable tip part that is not steerable. The steerable tip part may include: a first steerable tip part having a first length and bent in a first angle with respect to the non-steerable tip part; and a second steerable tip part having one end connected to the first steerable tip part, having a second length, and bent and steered into a second angle with respect to the non-steerable tip part. The first steerable tip part may be positioned farther from the non-steerable tip part than the second steerable tip part. The first length of the first steerable tip part may be smaller than a sum of lengths of steerable tip parts other than the first steerable tip part, and the first angle may be steered so as to be larger than the second angle.

Abstract: Provided is a haptic interface for allowing various information exchange in addition to transmitting accurate force information to an operator, and more particularly, a haptic device capable of transmitting more various kinds of information by transmitting necessary information to an operator by means of different kinds of sensations such as sight sensation, acoustic sensation, smell sensation, taste sensation or the like in addition to tactile sensation.In addition, provided is a haptic device, which may have an input point and an output point in accordance with each other or in discordance from each other, may have various output points to give a feedback to various points desired by an operator, may give a feedback by adjusting intensity of an output instead of outputting simple on/off signals when providing information to an operator by means of a feedback, and allows a feedback output intensity to be calculated in various ways according to an input amount and fed back to the operator when the input amount input through a haptic interface by the operator is adjustable.

Abstract translation: 提供了一种用于允许除了向操作者发送精确的力信息之外的各种信息交换的触觉接口，更具体地，涉及能够通过不同种类的感觉向操作者发送更多种类的信息的触觉装置 例如视觉，听觉，嗅觉，味觉等，除了触觉之外。 此外，提供了可以具有彼此相互依赖或彼此不一致的输入点和输出点的触觉装置，可以具有各种输出点，以向操作者期望的各个点给出反馈，可以给出 通过调整输出的强度而不是在通过反馈向操作者提供信息时输出简单的开/关信号的反馈，并且允许根据输入量以各种方式计算反馈输出强度并反馈到 当由操作者通过触觉界面输入的输入量是可调节的。

Abstract: The present invention relates to a direction-controllable drug injection catheter. According to the present invention, provided is the catheter extending along a central axis “A” including a drug injection part in which a drug injection channel has been formed; a channel opening and closing means which opens and closes the drug injection channel; and a steering structure which is rotationally asymmetric with respect to the central axis “A” and varies according to a pressure change of the drug injection channel for the purpose of steering.
