Abstract
A treatment device is disclosed, which includes a dissecting section main body which is configured to dissect tissue in a living body when inserted into the living body along a blood vessel, and which has a slit permitting a branch vessel branched from the blood vessel to enter into the slit, a stanching section which is disposed at the slit and which presses and cauterizes the branch vessel introduced into the slit, and a cutting section which is disposed at the slit and which cuts the cauterized branch vessel.

A treatment device comprising:
- a dissecting section main body which is configured to dissect tissue in a living body when inserted into the living body along a blood vessel, and which has a slit permitting a branch vessel branched from the blood vessel to enter into the slit;
- a stanching section which is disposed at the slit and which presses and cauterizes the branch vessel introduced into the slit, at least a part of the stanching section configured to be displaceable in a separating direction of a first inner surface and a second inner surface, wherein the first inner surface and the second inner surface face each other and define the slit, and the stanching section includes a stationary section fixed on one of the first inner surface and the second inner surface, and a pressing section disposed between the first inner surface and the second inner surface and which constitutes a free end on a proximal side of the stationary section, and wherein the free end on the proximal side of the stationary section is configured to contact the blood vessel;
- and
- a cutting section which is disposed at the slit and which cuts the cauterized branch vessel.

- a stanching section which is disposed at the slit and which presses and cauterizes the branch vessel introduced into the slit, wherein at least a part of the stanching section is configured to be displaceable in a separating direction of a first inner surface and a second inner surface, wherein the first inner surface and the second inner surface face each other and define the slit, and wherein the stanching section includes a first electrode and a second electrode which constitute bipolar electrodes, and wherein the stanching section includes a stationary section fixed on one of the first inner surface and the second inner surface, and a pressing section disposed between the first inner surface and the second inner surface and having a free end on a proximal side of the stationary section and configured to contact the blood vessel;
- and
- a cutting section which is disposed at the slit and which cuts the cauterized branch vessel.
A method for dissecting tissue, the method comprising:
- introducing a dissecting device having a dissecting section main body which is configured to dissect tissue into a living body along a blood vessel, the dissecting device having a slit, which permits a branch vessel branched from the blood vessel to enter into the slit;
- cauterizing the branch vessel introduced into the slit in a stanching section which is disposed at the slit, and wherein at least a part of the stanching section is configured to be displaceable in a separating direction of a first inner surface and a second inner surface, wherein the first inner surface and the second inner surface face each other and define the slit, the stanching section including a stationary section fixed on one of the first inner surface and the second inner surface;
- contacting the blood vessel with a pressing section disposed between the first inner surface and the second inner surface and which constitutes a free end on a proximal side of the stationary section;
- and
- cutting the cauterized branch vessel with a cutting section which is disposed at the slit.
