The present invention is a method of treating a wound in a sac-like cavity inside of a subject using negative pressure therapy. In the treatment method, an applicator connected to a negative pressure source and a closing member that closes an opening of the sac-like cavity are inserted to the sac-like cavity. The applicator is placed in the sac-like cavity and the closing member is placed in contact with the edge of an opening section of the sac-like cavity. The negative power source is driven, and a negative pressure of a desired value is applied to the sac-like cavity from the negative pressure source. The negative pressure of the desired value in the sac-like cavity is maintained, and negative pressure therapy is performed.

A tissue capturing device is formed by a substantially circular cylinder-shaped container, a filter member, and a lens member. The filter member is provided with a substantially circular plate-shaped partitioning portion, and a circular column portion that is formed substantially in the shape of a circular column and that is provided coaxially with a top surface of the partitioning portion. Recessed portions that have a sufficient size to enable them to capture biological tissue are formed in a circumferential wall portion of the circular column portion. Tissue capturing surfaces are formed in bottom surfaces of the recessed portions. A plurality of micro through holes that penetrate as far as a bottom surface of the partitioning portion are formed in the tissue capturing surfaces of the recessed portions. A lens member is also mounted on the container. The mounting position of the lens member is a position that faces the tissue capturing surfaces.
摘要:
A suture instrument that is inserted into a body and ejects an elongated anchor to be engaged to tissue, consisting of: an elongated member that extends from a proximal end on a hand side to a remote end that is introduced to tissue and has flexibility; a needle that is provided at the remote end of the elongated member, has at the distal end a sharp tip that is capable of puncturing tissue, is capable of housing a plurality of the anchors inside, and is provided with a side hole through which the anchors are capable of passing; a pusher whose remote end abuts the anchor that is housed in the needle and is disposed in a manner to be capable of moving in the axial direction of the elongated member; and a push-out control portion that is provided in the needle or the pusher and changes the movement direction of the anchor that has been moved to a formation position of the side hole by the pusher from the length-wise direction of the needle to a direction heading toward the side hole.

An ultrasonic endoscope includes an insertion section, an operation section, an optical observation system, and an ultrasonic observation system. The optical observation system is disposed in the insertable section, and has an objective lens located on a face of a distal end of the insertion section. The ultrasonic observing system is disposed in the insertion section, and has an ultrasonic transducer disposed on the face of the distal end of the insertion section or further forward than the distal end.
摘要:
A suture instrument includes a gripping portion that grips a plurality of tissue pieces by sandwiching them, and a suture needle that punctures and sutures the plurality of tissue pieces, the suture needle is supported so as to be able to move forwards or backwards relative to the gripping portion, and a direction of the forward or backward movement of the suture needle is set in a direction that intersects the tissue pieces gripped by the gripping portion.
