In addition, blade 32 can be maintained in predetermined temperature range.In this configuration, clinicist is by the temperature upper limit of predetermined temperature range and lower limit input fluid control system 90.Configuration before being similar to, temperature upper limit and lower limit can be preset.When heat of blade galvanic couple 94a determines the temperature of blade 32 close to temperature upper limit, fluid control systems 90 activates pump 92 (or increasing the speed of fluid pumping), thus the temperature of cooling or reduction blade 32.When fluid control systems 90 determines the temperature of blade 32 just close to lowest temperature by the measurement of heat of blade galvanic couple 94c, fluid control systems 90 stops pump 92 (or reducing the speed of fluid pumping), thus stops (or minimizing) through the flowing of the cooling fluid of blade 32.
Additionally or alternatively, blade cooling system 80 can be configured to cool blade 32 after clinicist has activated or stopped blade 32.In this configuration, blade 32 is allowed to heat up when being used to cutting and/or solidified structure, but is not just therefore actively cooled by blade cooling system 10 by use once blade 32.In this configuration, when heat of blade galvanic couple 94a determine the temperature of blade 32 exceed temperature upper limit and activated sensors 94d (or other suitable mechanisms) determine activator button 24 be in unclamp (actuating) position time, fluid control systems 90 activates pump 92.When the temperature of blade 32 reaches lowest temperature, or when activator button 24 be in press down (actuating) position time, fluid control systems 90 stops pump 92.Fluid control systems 90 can also comprise clamp sensor 94b (or other suitable mechanisms) to determine the position of fixture 58, namely opens or closes.When by clamp sensor 94b, fixture 58 determines that temperature that is in an open position and blade 32 exceedes temperature upper limit, fluid control systems 90 activates pump 92.On the other hand, when the temperature of fixture 58 or blade 32 is lower than lowest temperature, fluid control systems 90 stops pump 92.
