The present invention relates to a micro-robot control apparatus. An electromagnetic module for focusing magnetic field and a micro-robot control apparatus comprising the electromagnetic module, according to the present invention, focus the magnetic field in an area of interest where focusing of same is desired to allow a micro-robot to be controlled, and, the apparatus having been simplified, allow efficient setup and operation in the surgery area. Moreover, the number of electromagnets is reduced to thus reduce the number of sources of power, thereby resulting in efficient operation of the apparatus with lowered power consumption. Additionally, by means of a magnetic induction frequency signal reception coil of the micro-robot and the external micro-robot control apparatus equipped with a magnetic induction transmission coil, the micro-robot control apparatus can both generate power wirelessly for the micro-robot, and implementation location recognition of same due to the efficiency of the generated power.

Micro-robot control apparatus

A micro-robot operating system using an ultrasonic transducer according to an embodiment of the present invention may comprise: a micro-robot moving in an inspection object; and a micro-robot operating device for controlling the location of the micro-robot. A micro-robot operating device using an ultrasonic transducer may comprise: an ultrasonic transducer unit including a plurality of ultrasonic transducers; and a control unit for controlling the plurality of ultrasonic transducers, wherein the plurality of ultrasonic transducers are arranged to form a curved surface toward a particular location in a space.

The present invention relates to a capsule-type endoscope assembly which can be assembled or disassembled in a digestive organ of an examinee, and a capsule-type endoscope system using the same. A capsule-type endoscope of the present invention can be actively operated by the application of an external magnetic field. In addition, according to the present invention, after an examinee has separately swallowed various diagnosis and treatment devices modularized according to a purpose of diagnosis and treatment, the diagnosis and treatment devices can be assembled in a digestive organ of the examinee. Therefore, a function of a capsule-type endoscope can be extended to various diagnosis and treatment areas conventionally covered by a conventional general endoscope.

Magnetically actuated articular cartilage regeneration system

Disclosed herein are an adjustable-bending stiffness steerable needle, a buckling-preventing steerable needle, and a steerable needle system including the same. The adjustable-bending stiffness steerable needle includes a cylindrical core wire, a tip portion, a needle shaft, a compression spring, and a rigid shaft. The tip portion has a bevel shape, and is connected to the front end of the core wire. The needle shaft is disposed such that one end thereof is separable from the tip portion and the needle shaft surrounds the core wire. The compression spring is fastened to the other end of the needle shaft, and is configured such that the core wire passes therethrough. The rigid shaft is connected to the core wire having passed through the compression spring, and is also connected to the compression spring. The needle shaft includes a plurality of hollow tube elements that is separable from each other.
