Abstract: Provided is a spacer for ionizing radiation therapy, which can be easily disposed in a living body, does not require abdominal surgery for removing the disposed spacer after radiation therapy, and can effectively separate a tissue to be treated from other tissues. The spacer for ionizing radiation therapy includes a fiber assembly obtained by three-dimensionally entangling a fibrous material formed of a biocompatible synthetic polymeric material. Specifically, the spacer has a thickness of 1 mm to 100 mm.

Abstract: The present invention has an object to provide an ocular insert device that can be stably placed under the eyelid without giving a feeling of insertion of a foreign body to a user and that can store a larger volume of drug as compared to a conventional system. The ocular insert device 100 includes a storage main body 1 that is formed to be a seed-shaped piece having a predetermined width so as to be located under an eyelid and that stores a drug. The storage main body 1 has a held portion 1a in which a surface that comes into contact with the eyelid can be held by a tarsal plate 52.

Abstract: A surgical fluid-absorbing instrument to enable absorption of an amount of fluid several times as large as by a conventional surgical sponge system and to substantially decreased the times of changing surgical sponges during surgery. A tip sponge part, a retaining sponge part for absorbing the fluid, provided on a position continued from the tip sponge part, and a tubular handle part in which the tip sponge part is loaded are provided. At least the retaining sponge part is water-absorbing. The water-absorbing sponge may be compressed in one direction and solidified, or the water-absorbing sponge may extended in one direction and swollen.

Abstract: An endoscopic forceps is provided. A movable blade electrode and a fixed blade electrode form a pair of electrodes. The fixed blade electrode is electrically contacted onto an external electric conductor of a coaxial cable in the sheath conduit. A force application point of the movable blade electrode is connected to a center electric conductor of the coaxial cable. A pivot point of the movable blade electrode is provided on the movable blade electrode. The coaxial cable is slid with respect to the sheath conduit so that parallel moving added to the coaxial cable is transmitted to the movable blade electrode as turnable moving about the pivot point via the force application point of the movable blade electrode. A high frequency wave can be applied between the movable blade electrode and the fixed blade electrode via the external electric conductor and the center electric conductor of the coaxial cable.

Abstract: The present invention provides a bipolar needle type microwave operation device, wherein at least one pair of rod-like electrodes are parallel to a center axis of the electrodes in their entirety, an insulator being filled between the paired electrodes. Preferably, at least two pairs of electrodes are alternate so that the electrodes having the same polarity are not adjacent to each other, and the ends of the paired electrodes having the same polarity are bridged with the same material as the electrodes. Preferably, a perpendicular distance between each of the electrodes and the center axis is within 2 mm.

Abstract: An apparatus for separating suspended solids from a liquid includes a tank, a floating bed of granular filter material held at the upper portion of the tank at the time of filtration, a feed pipe for feeding the liquid at a position between a filtering section and a sedimenting section, a hollow member or members which are arranged within the tank at a position below the position of the filter bed but above the position of the feed pipe, an air supply pipe which blows air up through the hollow member or members, thereby creating a turbulence required for effective backwashing, an arrangement for bringing the filter bed down to a position where the lowermost surface of the filter bed is held below a position substantially flush with the top end of the hollow member or members, a means for discharging a filtrate from the tank which is arranged in the top portion thereof, and a means for discharging a deposit of the suspended solids from the tank, which is equipped at the bottom portion thereof.
