Abstract:
A surgical system for sealing a hollow organ, the surgical system including: a pair of electrodes; a memory storing data which include patterns corresponding to predetermined burst pressure value; an electrosurgical generator configured to generate a high frequency current for sealing the hollow organ; and one or more processors configured to: perform the sealing by application of the high frequency current through the hollow organ; measure impedance of the hollow organ between the pair of electrodes with time during the performing the sealing; subsequent to performing the sealing, classify parameters related to the impedance as one of patterns corresponding to predetermined burst pressure value according to the data; and estimate the burst pressure value of the hollow organ based on the one of patterns.
Abstract:
A living tissue bonding system includes a treatment instrument having a heating element which applies thermal energy to living tissue, an element temperature measuring section configured to measure an element temperature T1 of the heating element, a power source configured to generate power, a first calculating section configured to estimate a temperature difference ΔT between the element temperature T1 and a temperature T2 of the living tissue using a table or an equation stored beforehand in order to estimate the temperature difference ΔT based on an output value of the power source, a second calculating section configured to estimate the tissue temperature T2 from the element temperature T1 and the temperature difference ΔT estimated by the first calculating section, and a control section configured to control the power source based on the tissue temperature T2 estimated by the second calculating section.
Abstract:
A heating treatment apparatus to treat a living tissue by heating the living tissue includes a first holding member and a second holding member, a first heat generating element provided on the first holding member, a second heat generating element provided on the second holding member, a power supply unit supplying electric power to cause the first heat generating element and the second heat generating element to generate heat, and a control unit controlling operations of the power supply unit. The control unit switches a mode between a first mode and a second mode during treatment of the living tissue. Temperatures of the first heat generating element and the second heat generating element are controlled to the same temperature in the first mode and to different temperatures in the second mode.
Abstract:
