摘要:
A blunt dissector (11) for separating a blood vessel from surrounding tissues in a body comprises a longitudinal rod (16) having a proximal end, a distal end, and an internal passage for conducting insufflation gas between the proximal and distal ends. An interior sleeve (23) is mounted within the longitudinal rod (16) for receiving an endoscope (10) at the proximal end. A transparent tip (18) is mounted to the distal end of the longitudinal rod (16). A handle (17) is mounted to the proximal end of the longitudinal rod (16). The longitudinal rod (16) has an outer surface along substantially all of the longitudinal rod (16) between the proximal and distal ends consisting essentially of a fluoropolymer.

摘要:
There is disclosed a living tissue harvesting apparatus according to one aspect of the present invention, comprising a sheath (10) which can be inserted in a body through a cut skin portion, an endoscope (4) inserted through the sheath, a cutting device (18) which is disposed at the sheath (10) and which can cut a living tissue, and a holder (21) which is disposed at the sheath (10) to hold a harvesting object tissue in the body and which includes a press discharge portion (49) to press-discharge the harvesting object tissue in a direction detached from the cutting device (18), wherein the holder (21) includes a hook portion (55) to catch the living tissue in a position disposed opposite to the cutting device (18), and the cutting device (18) and hook portion (55) can move with respect to each other.
