MEDICAL TREATMENT APPARATUS AND CONTROL METHOD OF MEDICAL TREATMENT APPARATUS
A medical treatment device to treat and join body tissues, includes at least a pair of holding members which is configured to hold the body tissues to be treated, an energy output portion provided in at least one of the pair of holding members and connected to an energy source to form a joined portion by supplying energy to the body tissues held by the pair of holding members to join the body tissues, and a discharge portion which is configured to discharge a substance to cover a surface layer of the joined portion of the body tissues with the substance which prevents infiltration of a fluid into the joined portion after the joined portion is formed.
1 . A medical treatment apparatus to treat and join body tissues, the medical treatment apparatus comprising:
at least a pair of holding members which is configured to hold the body tissues to be treated;
an energy output portion which is provided in at connected to an energy source and which is configured to supply energy to the body tissues held by the pair of holding members and configured to form a joined portion of the body tissues;
a discharge portion which is configured to discharge a substance which prevents invasion of a into the joined portion so as to cover a surface layer of the joined portion of the body tissues with the substance after the joined portion is formed; and
a controller which is configured to verify the output state of the energy from the energy output portion and which is configured to control the discharge portion to discharge the substance from the discharge portion after verifying the output state from the energy.
2 . The medical treatment apparatus according to claim 1 , wherein the substance which prevents the invasion of the fluid contains the substance which invades from the surface layer of the joined portion of the body tissues toward joined surfaces.
3 . The medical treatment apparatus according to claim 1 , wherein the discharge portion includes at least an opening provided on the holding members.
4 . The medical treatment apparatus according t claim 1 , wherein the discharge portion includes an auxiliary treatment device which is configured to discharge the substance which prevents the invasion to the fluid to the body tissues to be treated.
5 . A medical treatment apparatus according to claim 1 , further comprising the energy source configured to supply energy to the body tissues.
6 . The medical treatment apparatus according to claim 1 , further comprising a fluid source configured to store a substance which prevents invasion of a fluid into the body tissues to be treated and configured to discharge the substance from the discharge portion.
7 . The medical treatment apparatus according to claim 1 , wherein the energy source is configured to output at least one of a high-frequency wave, microwave, a heater, laser light, and ultrasonic energy through the energy output portion in such a way that energy is given to the body tissues to heat the body tissues.
8 . A control method of a medical treatment apparatus to treat and join body tissues, comprising:
supplying energy to an energy output portion, which is provided in a holding member to hold the body tissues, from an energy source so as to form a joined portion in the body tissues;
judging the supplying the energy with controller; and
controlling discharge of a substance which prevents invasion of a fluid into the joined portion, from a surface layer to a joined surface of the joined portion with the controller, depending on result of the judging the supplying the energy, so as to cover the joined portion with the substance which prevents the invasion of the fluid.
9 . The control method according to claim further comprising moving a cutter so as to cut the joined portion of the body tissues, depending on the result of the judging.
