Abstract: A print element substrate is absorbed and held by a handling jig to define a predetermined location and position of the print element substrate with respect to the supporting member. In this instance, the handling jig is provided with a convex portion. Therefore, when the print element substrate is joined to the supporting member, the convex portion comes into contact with a surface of the supporting member, so that it is possible to define the height of the print element substrate with respect to the joining surface. This makes it possible to control the amount and height of squash by the print element substrate exerted on the adhesive agent applied on the joining surface. It is possible to prevent the redundant adhesive agent from spilling out in a print liquid flow path.

Abstract: A dissecting device that includes a grasping section and a dissecting member. The grasping section has an insertion lumen that permits an imaging device to be positioned therein. The dissecting member is at the distal portion of the grasping section and is insertable into a living body and movable along a blood vessel to dissect tissue surrounding the blood vessel. The dissecting member includes a base part having a lumen that communicates with the insertion lumen and a dissecting section which extends distally from the base part. The dissecting section is configured to dissect the tissue in the living body when the dissecting member is moved along the blood vessel. The dissecting member includes a blood vessel guide passage that accepts a branch vessel branched from the blood vessel at the distal portion of the dissecting member and guides the branch vessel toward the base part.

Abstract: A vein harvesting device for harvesting a vein in a body comprises: an elongated hollow member possessing a distal end portion and a proximal end portion; and a dissecting member at the distal end portion of the elongated hollow member and configured to dissect tissue in the body surrounding the vein during harvesting of the vein, with the dissecting member possessing a proximal end portion communicating with the elongated hollow member, and the dissecting member also possessing a distal end portion. The distal end portion of the dissecting member is an upturned distal end portion that is upturned toward a distal-most end of the distal end portion, and the upturned distal end portion of the dissecting member contacting tissue surrounding the vein during the harvesting of the vein.

Abstract: A vein harvesting device for harvesting a vein in a living body includes an elongated hollow member possessing a distal end portion and a proximal end portion, and a dissecting member at the distal end portion of the elongated hollow member and configured to dissect tissue in the body surrounding the vein during harvesting of the vein, wherein the dissecting member possessing a proximal end portion communicating with the elongated hollow member. The dissecting member possesses two side portions, with each of the side portions possessing a first end at an end of the side portion farther from the hollow member and a second end at an end of the side portion closer to the hollow member. A projection projects from the first end at each of the side portions of the dissecting member to contact the tissue in the body surrounding the vein during the harvesting of the vein.

Abstract: A predetermined amount of an ink absorber, which is a fiber assembly in which intersections between fibers are not fused together, is charged into a compression and insertion apparatus. A rectangular parallelepiped-shaped insertion block is moved to an upper surface portion of the absorber, and one face of the ink absorber is pushed by a side plate. As such, a part excluding the part of the ink absorber which faces the side plate is compressed and surrounded. In this state, the ink absorber is compressed by the side plate. The ink absorber is inserted into a tank case by making a bottom plate slide, thereby opening the bottom face of the ink absorber and by moving down the insertion block.
