Abstract: A bag for use in a laparoscopic surgery, having at its one end an opening through which extracted internal organ is put in and drawn from, and having at its other end a tubular organ storage portion with a closed bottom, of which bore diameter is smaller than that of the opening. The bag is characterized by being made of a soft synthetic resin, and its way part extending from the opening to the tubular organ storage portion being curved in a manner it intersects with the direction in which extracted internal organ is put in and drawn from at said opening.

Abstract: A tissue excision and cutting apparatus used by being inserted into a trocar for cutting off a part of tissue as a sample piece for such a diagnosis in a laparoscopic surgery or the like. The apparatus comprises a resection blade having an inner hollow cylinder with a cutting blade at its tip end, and a forceps having at its tip end a clamp having a movable jaw capable of opening and closing which is joined to a fixed jaw with a chopping block piece, open-close mechanism having an operation part for opening and closing the movable jaw, and a longitudinal penetrating passage into which the resection blade is inserted and moves back and forth therein.

Abstract: A laparoscope apparatus for use in laparoscopic surgery or the like comprises a cannula with an inner hollow having therein a light guide for introducing light to its tip end for illuminating the object to be observed, and an endoscope which is capable of being pulled into and out from the inner hollow of the cannula. The cannula is airtightly sealed with a transparent member at its tip end, while the endoscope has therein an image pick-up with a wide-angle lens, and the image pick-up is housed in the cannula close to the transparent member.

Abstract: The panoramic radiographic apparatus of the present invention has a cassette holder capable of accommodating both a conventional film cassette and a digital sensor cassette loaded with an electric X-ray image detector, one at a time, in a rotary arm, wherein when a film cassette is mounted, the cassette holder is mechanically moved in accordance with the rotation of the rotary arm so as to carry out panoramic radiographing, and when a digital sensor cassette is mounted, without moving the cassette holder, the electric X-ray image detector is driven by supplying control signals corresponding to the rotation of the rotary arm to the digital sensor cassette to obtain image signals required for generating a panoramic X-ray image. Therefore, both the film cassette and the digital sensor cassette can easily be mounted, one at a time, whereby required panoramic X-ray images can be obtained by fully using the features of each type of cassette.
