Abstract: An upper limb restraint device 1 comprises a base 2 placed on the top surface of an upper limb rest 51, an upper limb rest engagement part 3 provided at an end of the base 2 close to the wrist joint 104 of an upper limb 100, an elbow joint supporting part 4 provided at the other end of the base 2 close to the elbow joint 102, and two strings 5 and 6. The upper limb rest engagement part 3 is formed in the shape of a pocket capable of receiving an end of the upper limb rest 51. The elbow joint supporting part 4 is formed to cover the elbow joint 102 of the upper limb 100 laid on the upper limb rest 51. The root ends of the strings 5 and 6 are attached to the elbow joint supporting part 4. The strings 5 and 6 are bound around the upper limb rest 51 with the elbow joint supporting part 4 covering the elbow joint 102.

Abstract: A bloodstream dilating device 1 is composed of an elastic member 2 extending in a direction of blood flow in a true lumen 115. The elastic member 2 pushes the inner wall of the true lumen 15 outward to dilate the bloodstream. An aortic dissection treating device includes an obturator and a fixing member for fixing the obturator to the inner layer of an aorta. The obturator is inserted up to the point that it can cover an entry port formed in the aorta. The obturator is deformed along the periphery of the entry port in the inner layer by blood pressure to occlude the entry port.

Abstract: A puncturing member 2 including a puncturing part 2a for puncturing a vein in which a varicosis is formed is formed of a conductor. A counter electrode plate 5 to be allowed to be in contact with the surface of an organism and a foot switch 18 are connected to an apparatus main body 4. An inverter circuit for generating high frequency power is provided in the apparatus main body 4. After the end part of a cylinder member 3 is allowed to puncture skin, the puncturing member 2 is inserted into the cylinder member 3 so that the puncturing part 2a punctures the vein in which the varicosis is formed. The high frequency power generated at the inverter circuit is supplied to the puncturing part 2a. Heat generated at the puncturing part 2a cauterizes the vein to block the bloodstream, thereby degenerating the vein.
