Abstract: A medical manipulator includes a surgical tool that has an end effector at a distal end and a drive unit that is detachable from a handle of the surgical tool. In a state where the drive unit is mounted on the handle, when a manipulation lever is manipulated, a driving force of a motor is transmitted to the handle, and the end effector is operated. Even in a state where the drive unit is detached from the handle, the surgical tool can be independently used by a manual manipulation.

Abstract: To provide a method and an instrument capable of easily and accurately measuring a size of an affected part present in a body of a patient, there is provided a measuring instrument 1 including at least four sheets of acrylic plates having indices of a substance of X-ray image forming performance of metal balls 2 and 3, metal wires and the like in which sets of two sheets of the acrylic plates are arranged in parallel to each other and a space defined by the sets of acrylic plates arranged in parallel, is provided with an interval capable of receiving a part of a patient to be measured, such as the head or the like.

Abstract: Disclosed is a catheter which is introduced into a blood vessel for the treatment or inspection of a diseased portion in the blood vessel. For facilitating the introducing operation of the catheter, a super-elastic wire is housed in the catheter body in a manner to extend in the longitudinal direction of the catheter body. The super-elastic wire may be fixed within the lumen of the catheter body, may be detachably provided, or may be embedded in a part of the catheter body. The exposed surface of the catheter body or the super-elastic wire may be covered with a layer of a watersoluble high molecular weight material. Also, an X-ray intransmissible material may be applied to the exposed surface of the catheter body or the super-elastic wire.
