A treatment system includes: an absorbent member which is arranged to be discharged into the biological tissues as the fusion targets from the first jaw, thermally deformed when the thermal energy is applied thereto; a first energy discharge portion which is configured to discharge the absorbent member toward the second holding surface, and which is configured to supply the high-frequency energy and the thermal energy to the biological tissues; a second energy discharge portion which is configured to come into contact with at least a part of the absorbent member when the absorbent member is discharged, and which is configured to supply the high-frequency energy and the thermal energy to the biological tissues; and a control unit which is configured to control the energy source to supply the thermal energy after discharging the absorbent member to the biological tissues.

A surgical device which is configured to apply energy to living tissue and to be used to perform a surgical procedure includes a grasping portion, an incising portion, an introduction portion and a treatment portion. The grasping portion grasps the living tissue having a first surface and a second surface. The incising portion is movable forward and backward with respect to the living tissue and incises the living tissue. The introduction portion is movable forward and backward with respect to the living tissue and introduces a biocompatible material, which is chemically bound with the living tissue, to a space between the first surface and the second surface. The treatment portion is configured to apply high-frequency energy and thermal energy to the living tissue.

Treatment device and treatment method

Regardless of the type of biological tissue, a sufficient joining force can be quickly obtained; the problem of an adhesive bonding biological tissue other than the target biological tissue can be prevented; and the adhesive can be prevented from becoming impossible to apply due to curing. There is provided a biological-tissue joining apparatus including an energy supplying part that clamps, with pressure, biological tissue to be joined and melts protein in the clamped biological tissue by supplying energy to the biological tissue; and an adhesive supplying part that supplies an adhesive to the biological tissue, wherein the adhesive supplying part includes a discharge port that discharges the adhesive to a contact surface of the energy supplying part in contact with the biological tissue.
