20100038402 | Hollow Tissue Inosculation Apparatus - A hollow tissue inosculation apparatus is to inosculate two hollow tissues to each other with a staple having a plurality of elastically deformable bent staple pins. The hollow tissue inosculation apparatus includes a staple holder to hold the staple, a curvature control mechanism to control curvature of the staple pins of the staple held in the staple holder, and a gap control mechanism to control gaps of the hollow tissues with respect to the staple holder. The curvature control mechanism substantially straightens the staple pins. The gap control mechanism reduces the gaps to cause the substantially straightened staple pins to penetrate through the hollow tissues. The hollow tissue inosculation apparatus also includes a detector to detect the staple pins of the staple that have penetrated through the hollow tissue. | 02-18-2010 |
20100072249 | HOLLOW TISSUE INOSCULATION APPARATUS - A hollow tissue inosculation apparatus is to inosculate two hollow tissues to each other with a staple having a plurality of elastically deformable bent staple pins. The hollow tissue inosculation apparatus includes a staple holder to hold the staple, a curvature control mechanism to control curvature of the staple pins of the staple held in the staple holder, an incision mechanism to incise the hollow tissues, and a gap control mechanism to control gaps between the staple holder and the hollow tissues. The curvature control mechanism substantially straightens the staple pins. The gap control mechanism reduces the gaps to cause the substantially straightened staple pins to penetrate through the hollow tissues. The staple holder prevents the ring member of the staple from expanding at least until the incision of the hollow tissues is completed. | 03-25-2010 |
20100072250 | HOLLOW TISSUE INOSCULATION APPARATUS - A hollow tissue inosculation apparatus is to inosculate two hollow tissues to each other with a staple having a plurality of elastically deformable bent staple pins. The hollow tissue inosculation apparatus includes a staple holder to hold the staple, a curvature control mechanism to control curvature of the staple pins of the staple held in the staple holder, an incision mechanism to incise the hollow tissues, and a gap control mechanism to control gaps between the staple holder and the hollow tissues. The curvature control mechanism substantially straightens the staple pins. The gap control mechanism reduces the gaps to cause the substantially straightened staple pins to penetrate through the hollow tissues. The incision mechanism includes two cutters to incise the hollow tissues, respectively. The staple holder holds the staple so that the blades of the cutters do not come into contact with the staple. | 03-25-2010 |
20100076466 | HOLLOW TISSUE INOSCULATION APPARATUS - A hollow tissue inosculation apparatus is to inosculate two hollow tissues to each other with a staple having a plurality of elastically deformable bent staple pins. The inosculation apparatus includes a staple holder to hold the staple, a curvature control mechanism to control curvature of the staple pins of the staple held in the staple holder, an incision mechanism to incise the hollow tissues, and a gap control mechanism to control gaps between the staple holder and the hollow tissues. The curvature control mechanism straightens the staple pins. The gap control mechanism reduces the gaps to cause the straightened staple pins to penetrate through the hollow tissues. The inosculation apparatus further includes a stenosis detecting element to detect a stenosis part of one of the hollow tissues. The stenosis detecting element is located at a position spaced apart from the staple held in the staple holder. | 03-25-2010 |
20100076467 | STAPLE TO INOSCULATE HOLLOW TISSUES - A staple is to inosculate two hollow tissues to each other. The staple includes an elastically deformable ring member and elastically deformable pins fixed to the ring member. The pins are bent toward the inside of the ring member. | 03-25-2010 |
20100076468 | HOLLOW TISSUE INOSCULATION APPARATUS - A hollow tissue inosculation apparatus is to inosculate two hollow tissues to each other with a staple having a plurality of elastically deformable bent staple pins. The hollow tissue inosculation apparatus includes a staple holder to hold the staple, a curvature control mechanism to control curvature of the staple pins of the staple held in the staple holder, an incision mechanism to incise the hollow tissues, and a gap control mechanism to control gaps between the staple holder and the hollow tissues. The curvature control mechanism substantially straightens the staple pins The gap control mechanism reduces the gaps to cause the substantially straightened staple pins to penetrate through the hollow tissues. The incision mechanism includes two cutters to incise the hollow tissues, respectively, and locates the blades of the cutters between the hollow tissues to incise them from their outside. | 03-25-2010 |
20100076469 | HOLLOW TISSUE INOSCULATION APPARATUS - A hollow tissue inosculation apparatus inosculate two hollow tissues with a staple having elastically deformable pins. The inosculation apparatus includes a holder to hold the staple, a curvature control mechanism to control curvature of the pins of the staple held in the holder so as to straighten the pins, and a gap control mechanism to control gaps between the holder and the hollow tissues so as to reduce the gaps to cause the straightened pins to penetrate through the hollow tissues. The gap control mechanism includes two support mechanisms to support the hollow tissues and a mechanism to move the support mechanisms with respect to the holder. The support mechanisms include supports to support the hollow tissues when the pins are stuck into the hollow tissues. Contact parts of the supports with the hollow tissues are spaced apart from positions where the pins penetrate through the hollow tissue. | 03-25-2010 |
20100181363 | HOLLOW TISSUE INOSCULATION APPARATUS - A hollow tissue inosculation apparatus is to inosculate two hollow tissues to each other with a staple having a plurality of elastically deformable bent staple pins. The hollow tissue inosculation apparatus includes a staple holder to hold the staple, a curvature control mechanism to control curvature of the staple pins of the staple held in the staple holder, and a gap control mechanism to control gaps of the hollow tissues with respect to the staple holder. The curvature control mechanism substantially straightens the staple pins. The gap control mechanism reduces the gaps to cause the substantially straightened staple pins to penetrate the hollow tissues. The curvature control mechanism and the gap control mechanism are independent from each other. | 07-22-2010 |
20100245846 | OPTICAL ENCODER, BENDING OPERATION SYSTEM, AND METHOD OF DETECTING DISPLACEMENT OF LINEAR POWER TRANSMISSION MEMBER - An optical encoder includes a linear power transmission member which moves longitudinally, a reflector which is provided on an outer peripheral surface of the linear power transmission member and which is longitudinally movable integrally with the linear power transmission member, the reflector including two kinds of reflecting portions different in reflectance are longitudinally arranged, and a light source which radiates light. Further, the optical encoder includes a linear light transmitter which guides the light from the light source to the reflector and to which reflection light reflected from the reflector is guided, and a calculation mechanism configured to calculate a longitudinal displacement of the reflector on the basis of an intensity of the reflection light from the reflector which is guided via the linear light transmitter. | 09-30-2010 |
