Control the temperature of knife head for surgical, so that scalpel is stopped blooding in operation process, and doctor need not be concerned about the temperature of knife head for surgical, greatly
The difficulty of operation is reduced on degree.Solve and need doctor actively to adjust asking of knife head for surgical temperature using endotherm knife at present
Topic.Make doctor need not consider, in the physical and mental operation of input patient of the factor of equipment, to improve operation matter in operation process
Amount.
Brief description
Fig. 1 is the intelligent temperature control scalpel schematic diagram of the present invention；
Fig. 2 is the structural representation of the present invention.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
A kind of intelligent temperature control electric heated scalpel, including scalpel 6 and intelligent temperature control equipment 8, scalpel 6 includes cutter head 1, electricity
Thermoconverter 2, critesistor 4, blade holder 3 etc., by electrothermal transducer heated blade head surface temperature, critesistor monitors handss
Art bit interface temperature, temperature signal is transmitted to intelligent temperature control equipment 8 by data wire 5.And intelligence is accepted by data wire 5
The instruction that temperature control device 8 is sent controls the electrical power of electrothermal transducer to play the function of controlling bit interface temperature.
Intelligent temperature control equipment 8 includes single-chip microcomputer, power driving circuit, display device 7 etc..Intelligent temperature control equipment 8 passes through number
Receive the temperature signal that scalpel transmits according to line 5, A/D conversion carries out calculating analysis, if temperature signal downward trend, passes through
Regulation power supply drive circuit, increases the electrical power of electrothermal transducer in scalpel, plays heats, and heating that can be intelligent is performed the operation
Knife surface temperature, controls the bit interface temperature that critesistor detects in threshold range.In the same manner, when critesistor detects
The trend that bit interface temperature rises, then single-chip microcomputer regulation power supply drive circuit, reduces the electrical power of drive circuit, thus reducing
The temperature on knife head for surgical surface, controls the bit interface temperature that critesistor detects in threshold range.And display device
Show the use state of cutter head in real time, point out doctor to use.
As preferred embodiment, because scalpel surface temperature declines naturally and contacts at a temperature of tissue of patient causes
The trend of fall is different.In single-chip microcomputer memory storage insert contacts tissue of patient, the temperature of critesistor reduces variation tendency；
