Abstract: Clip forceps have a pair of clamp members each having a clamp portion and a handle portion extending from the clamp portion. The pair of clamp members cross each other so as to have an X-shaped configuration and are pivotally coupled together at their point of intersection. Grip portions extend from the respective handle portions so that the clamp portions can be moved toward and away from each other by moving the grip portions. Each of the grip portions is curved inwardly, has a semi-oval cross section and has a plurality of projections which provide the outer surface thereof.

Abstract: A surgical clip has projections on its load-bearing portion. Also, a forceps used with the surgical clip is formed with depressions or small holes to receive the projections on the surgical clip.

Abstract: A pair of bipolar diathermy forceps used for surgery having two arms electrically insulated from each other and adapted to keep opening their tips usually, comprising a tube which extends toward the inside tips of the arms and which is mounted along a groove, the said groove is provided on either or both of the arms, an elongate section which follows the said groove, an operational section inserted between two arms whereby a hole of the tube is open, when the said arms are closed and is closed when they are open, and a pouring section of physiological saline which is connected to the end of the tube. Irrigation is started when the arms are closed and is stopped when they are open automatically. When the tissue is held by the tips of arms and supplied with the current, the coagulation is caused by the high frequency conducted, whereby the control of hemorrhage is completed. The frequent saline irrigation of the work area in microsurgery and the dilution of a little bleeding can be obtained.

Abstract: An aid for molding a filling material used in the cranioplasty to fill in a defective part of the skull. The aid allows a quick, efficient molding. It includes a bar made of an elastic material and being of a substantially L-shape section and a core member embedded therein to maintain the aid in a desired position.
