Abstract: A medical tube includes a connection portion that is removably attached to an end of a catheter including a guide wire lumen through which a guide wire is inserted and a tube main body that includes a lumen through which the guide wire is inserted. The lumen communicates with the guide wire lumen while being attached to the end of the catheter through the connection portion.

Abstract: A medical manipulator includes: a manipulator body that has a handle; a drive unit that can be detachably attached to the handle; and an attachment limiting mechanism that is provided to the handle. When the number of times that the drive unit has been attached to and detached from the handle reaches a set number, the attachment limiting mechanism prevents the mounting of the drive unit to the handle. The attachment limiting mechanism has a counting mechanism and a stopper. The counting mechanism counts the number of times that the drive unit is attached and detached. When the count reaches a set number, the stopper is made to protrude into a mounting hole in the handle so as to prevent the insertion of the drive unit into the mounting hole.

An apparent shape of the solid-state image pickup device viewed from a front surface side of the body mount is a rectangle in which one or more corners are oblique.

Abstract: An accommodation tool is disclosed with which an operator can easily wind and accommodate a flexible medical elongated body. An accommodation tool winds and accommodates the flexible medical elongated body, for example, a guide wire. The accommodation tool has an inner wall, an outer wall, and an interlock wall. The guide wire is wound around the inner wall. The outer wall defines an accommodation space for accommodating the guide wire between the inner wall and the outer wall, and that is disposed further outward in a radial direction from a centroid of the accommodation tool than the inner wall. The interlock wall interlocks one end portion of the inner wall and one end portion of the outer wall with each other.

Abstract: A camera includes: a ring-like body mount having an inside diameter smaller than about 48 millimeters; and a solid-state image pickup device arranged oppositely to the body mount, the solid-state image pickup device having a rectangle light receiving section with a diagonal line length of about 43 millimeters or more. An apparent shape of the solid-state image pickup device viewed from a front surface side of the body mount is a rectangle in which one or more corners are oblique.

Abstract: A diagnostic imaging catheter is disclosed which includes a drive shaft, of which a distal portion is provided with a signal transmitting and receiving unit, and which can be rotated; a sheath including a lumen into which the drive shaft is inserted such that the drive shaft can be moved forward and backward; a communicating hole which is provided in a distal portion of the sheath, and through which the inside and the outside of the sheath communicate with each other; and a valve body capable of opening and closing the communicating hole. The valve body is configured to be capable of switching between a closed state in which the communicating hole is covered and blocked with the valve body and an open state which the valve body enters by being moved to the outside of the sheath from the closed state, and in which the communicating hole is open.

Abstract: A catheter includes a sheath that is inserted into a lumen; a drive shaft that transmits mechanical drive force; a hub that moves the drive shaft; an outer tube that is provided in the sheath on a proximal side and comprises a first connector at a proximal portion; an inner tube that can move inside the outer tube; a second connector that can be connected to and disconnected from the first connector and can receive the inner tube; a sheath connection portion that connects the sheath and the outer tube; and a protective tube that protrudes toward a distal side further than the inner tube, accommodates the drive shaft, can be inserted into the outer tube and the sheath, and can be pulled out of the outer tube together with the hub and the inner tube as the second connector is disconnected from the first connector.

Abstract: A slip ring mechanism for a medical manipulator, the slip ring mechanism including: a rotating rod that rotates together with a drive shaft; rotating terminals that are positioned so as to be coaxial to the rotating rod; conductive members that contact the rotating terminals and are electrically connected to an end effector; holding members that hold the conductive members such that the conductive members are sandwiched between the holding members and the rotating terminals; and contact terminals that contact the rotating terminals so as to be capable of rotating and sliding relative thereto.

Abstract: A switch mechanism for a medical manipulator, the switch mechanism including a moveable switching operation part, moving-side contacts provided to the switching operation part, and fixed-side contacts capable of contacting the moving-side contacts.

Abstract: A medical manipulator wherein a first section provided with a driven coupling is detachably attached to a second section provided with a driving coupling that includes a drive source and is driven by the drive source. The driving coupling and the driven coupling are fitted to each other to transmit the drive force from the drive source to a tip-end operation part. In at least one coupling among the driving coupling and the driven coupling, tooth ends on the side where the fitting of the driving coupling and the driven coupling begins when the first section and the second section are connected become thinner towards the axial-direction end surface.
