A treatment system includes an energy source, a pair of holding portions, an output portion and a cooling section. To hold a living tissue of a treatment target, at least one of the pair of the holding portions relatively moves with respect to the other holding portion. The output portion is disposed on at least one of the holding portions and connected with the energy source. Moreover, the output portion thermally denatures the living tissue, when the energy is supplied from the energy source. The cooling section inhibits the thermal spread in a direction away from the output portion.
What is claimed is: 1. A treatment system which applies energy to a living tissue to perform a treatment, comprising: an energy source which supplies the energy; a pair of holding portions which hold the living tissue, at least one of the holding portions being configured to relatively move with re

The treatment system according to claim 1, wherein the cooling section includes a heat radiation member which is disposed at a position adjacent to the output portion and which suppresses the spread of the heat from the living tissue denatured by the heat to a surrounding area thereof. 3. The treatment system according to claim 1, further comprising: at least one fluid passage which is disposed at a position close to the output portion and which passes a fluid, the fluid passage being configured to pass the fluid including a gas and/or a liquid generated from the living tissue at a time when the living tissue is thermally denatured. 4. The treatment system according to claim 1, further comprising: at least one barrier portion disposed at a position adjacent to the output portion, wherein the barrier portion is disposed between the output portion and the cooling section. 5. The treatment system according to claim 4, wherein the cooling section is disposed at a height equal to that of the barrier portion or at a position lower than that of the barrier portion. 6. The treatment system according to claim 1, wherein the plurality of output portions are arranged on at least one of the holding portions. 7. A medical treatment method for a living tissue by use of the treatment system according to claim 1, comprising: holding the living tissue with holding portions; supplying the energy to the held living tissue from an energy source through an output portion thereof; directing a fluid, including a gas and/or a liquid generated from the living tissue to which the energy has been supplied, to discharge in a predetermined direction set by the holding portions; and cooling the fluid being discharged in the predetermined direction using a cooling section. 8. The medical treatment method according to claim 7, wherein the discharging of the fluid in the predetermined direction is carried out such as to substantially avoid influencing the living tissue. 9. A medical treatment method for a living tissue by use of the treatment system according to claim 1, comprising: holding the living tissue with holding portions; supplying the energy to the held living tissue to denature the living tissue from an energy source through an output portion thereof, to which the energy has been supplied; and discharging a fluid including a gas and/or a liquid generated from the denatured living tissue in a predetermined direction associated with the holding portion; and cooling a surrounding area of the denatured living tissue by using a cooling section, in order to prevent the thermal spread from the held living tissue to the surrounding area of the held living tissue. 10. The medical treatment method according to claim 9, wherein the discharging of the fluid in the predetermined direction is carried out such as to substantially avoid influencing the living tissue. 11. A treatment device which applies energy to a living tissue, comprising: a holding section which holds the living tissue, the holding section including: first and second holding portions which relatively move with respect to each other; an output portion disposed on at least one of the first holding portion and the second holding portion and connected with an energy source, the output portion being configured to thermally denature the living tissue by the energy supplied from the energy source at a time when the living tissue is held between the first holding portion and the second holding portion; and a cooling section which inhibits the spread of heat from the denatured living tissue to a surrounding area thereof; wherein the cooling section includes a first channel which is provided on the side of a holding surface for guiding a fluid containing a gas and/or a liquid generated from the living tissue denatured by the energy, and a conduit for circulating the fluid in at least one of the first holding portion and the second holding portion provided in the vicinity of the first channel. 12. The treatment device according to claim 11, wherein the cooling section further includes a cooling plate which comes into contact with the living tissue as well as the conduit. 13. The treatment device according to claim 12, wherein the cooling plate includes a barrier portion brought into close contact with the living tissue to prevent the fluid generated from the living tissue by the output portion from leaking outwardly from the holding section through a gap between the cooling plate and the living tissue. 14. The treatment device according to claim 12, wherein the cooling plate includes a fluid passage to pass a fluid which is disposed between the cooling plate and the output portion and which discharges, from the holding section, the fluid including a gas and/or a liquid generated from the living tissue. 15. The treatment device according to claim 11, wherein the cooling section includes a heat radiation member which radiates the heat spread from the denatured living tissue. 16. The treatment device according to claim 11, wherein the cooling section includes a cooling plate disposed on at least a holding portion provided with the output portion in the first and second holding portions, and cooling means for cooling the cooling plate. 17. The treatment device according to claim 16, wherein the cooling means includes a space to pass a fluid which cools the cooling plate between the cooling plate and the holding portion provided with the output portion in the first and second holding portions. 18.
