[0023]

[0024] First, the treatment system 10 of the first embodiment will be described.

[0025] Such as figure 1 As shown, the treatment system 10 includes a treatment instrument 11 , a power supply unit 12 , and a foot switch 13 . The treatment system 10 uses the power supply unit 12 to switchably apply high-frequency electric energy and thermal energy to living tissue grasped by the pair of jaws 36 a and 36 b of the treatment instrument 11 . In addition, hereinafter, the high-frequency power is simply referred to as "HF", and the power for heat generation is simply referred to as "TH". For example, high-frequency electric energy is called HF energy.

[0026] The treatment instrument 11 is connected to the power supply unit 12 via HF lines 22a, 22b and a TH line 23 . In addition, the HF lines 22a, 22b, the TH line 23, and the like each have two wirings, but are represented by one. The foot switch 13 is connected to the power supply unit 12 via a switch wire 21 .

no. 2 approach

[0102] Next, a treatment system 10A according to a second embodiment will be described. Since the treatment system 10A is similar to the treatment system 10 , the components having the same functions are denoted by the same reference numerals and description thereof will be omitted.

[0103] Such as Figure 8 As shown, in the treatment system 10A, in the TH energy application mode, the TH control unit 84 repeatedly performs the first control mode and the second control mode, and the first control mode is during the first control mode set time (tAset) A mode in which the temperature of the heater member 53 becomes the first temperature TA is controlled, and the second control mode is a mode in which the heating power source 83 is controlled to suspend the heating power (TH) during the second control mode set time (tCset). output such that the heater member 53 becomes a mode lower than the first temperature TA.

[0104] The temperature T of the heater member 53 increases in th...

[0108] Next, a treatment system 10B according to a third embodiment will be described. Since the treatment system 10B is similar to the treatment system 10 and the like, the same reference numerals are used to attach the same reference numerals to components having the same functions, and description thereof will be omitted.

[0109] Such as Figure 9 As shown, in the treatment system 10B, similarly to the treatment systems 10 and 10A, in the TH energy application mode, the TH control unit 84 repeatedly performs the first control mode and the second control mode. The first control mode is to control the heater unit 53 to The temperature becomes a mode of the first temperature TA, and the second control mode is a mode of controlling the heater member 53 to become a temperature lower than the first temperature TA.

[0110] Furthermore, in the treatment system 10B, when the temperature of the heater member 53 reaches the predetermined second temperature TD in the second control ...

Abstract

A treatment system 10 includes a high-frequency power source 73 which outputs high-frequency power, a power source 83 for heat generation which outputs power for heat generation, one pair of jaws 36a, 36b having one pair of electric conductors 52a, 52b which are disposed at respective grasping surfaces and a heater member 53 which is disposed at at least one of the jaws, and a control section 94 which performs control to start application of the thermal energy after application of the high-frequency power energy ends, repeats a first control mode of performing control such that the heater member 53 reaches a first temperature and a second control mode of performing control such that a temperature of the heater member 53 becomes lower than the first temperature, and controls the power source 83 for heat generation according to a temperature change parameter based on change in temperature of the heater member 53 so as to end application of the thermal energy.

Description

technical field [0001] Embodiments of the present invention relate to a treatment system including a pair of grasping members that sequentially apply high-frequency electric energy and thermal energy to grasped living tissue, and a control method of the above-mentioned treatment system. Background technique [0002] U.S. Patent Application Publication No. 2009 / 076506 discloses a treatment system, which includes: a pair of holding parts, which apply high-frequency electric energy and heat energy to the held biological tissue; high-frequency power supply, whose output is used for high-frequency power for applying high-frequency electric energy; a heat generating power supply that outputs heat generating power for applying heat energy; and a control unit that controls the high-frequency power supply and the heat generating power supply to switch between application of high-frequency electric energy and application of heat energy. [0003] In addition, US Patent Application Publ...
