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.

A medical treatment system (1, 20, 40) including an endoscope (100), a treatment tool (50, 70, 71,72) that is inserted in a channel (29, 30, 81A, 81B, 81C,102, 103) of the endoscope, and a holder (2, 21, 41, 45) that holds the treatment tool in a manner that enables a user who operates the endoscope to move the treatment tool forward and backward and rotate the treatment tool, with the treatment tool having a treatment portion (51) that performs treatment on a living body; a wire (52) for operating the treatment portion whose distal end is connected to the treatment portion; a sheath portion (53) that has a first sheath (57) that is formed with a coil and in which the wire is inserted in a manner capable of moving forward and backward in the axial direction, and a second sheath (58) that is formed with a coil of a plurality of layers and provided on the outside of the first sheath; and an operating portion (55) to which the base end of the wire is connected and enables forward/backward and rotation operation of the wire; and with the holder holding the operating portion so as to be in a predetermined positional relation with respect to the endoscope.
摘要:
A medical manipulator (1) which includes: a plurality of arms (10,11) formed in a cylindrical shape a distal end portion (3) of which is made of a rigid member having a bending portion (10A,11A) capable of bending; an insertion portion (2) made of a rigid member having a plurality of channels in which base ends of the plurality of arms are connected to a distal end of the insertion portion so as to connect lumens of the arms to the plurality of channels; a photographic device (5) provided at the distal end of the insertion portion; an operation portion (14A,15A) that operates the bending portion; and a transmission member (30) that connects the bending portion and the operation portion, in which the bending portion has: a first bending portion that is capable of bending in a predetermined direction by an operation of the operation portion, and a second bending portion provided in a base end than the first bending portion that is capable of fixing the plurality of arms in a bent state so as to mutually separate, and the transmission portion has: a first region (30A) which is flexible, and a second region (30B) which is rigid and connected to a base end portion of the first region.
