High frequency electric knife
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of high frequency electric knife.
Background technology
High frequency electric knife from be born till now over more than 80 year; Develop rapidly and of the higher requirement of domestic and international medical profession along with electronic technology to the operating theater instruments proposition; High frequency electric knife develops into functional diversities by function singleness, develops into present work station pattern by functional diversities again.
High frequency electric knife is under the situation of having only simple function or several kinds of functions; For example have only and purely cut, mix and cut; Electricity coagulates, bipolarly purely cut, bipolar mixing when simpler, less pattern such as cutting, and the charactron of traditions of the past, LED luminous tube, fine motion contact button man-machine dialog interface can also satisfy its basic demand.But existed and shown that quantity of information is not enough, demonstration information is difficult for distinguishing, operated complicated loaded down with trivial details problem.
Along with high frequency electric knife is used widely,, more requirement has been proposed for the mode of operation of high frequency electric knife such as the application in Wicresoft fields such as neurosurgery, department of otorhinolaryngology in medical field.
In the face of the higher requirement of renewal that the medical market constantly proposes high frequency electric knife, the charactron of traditions of the past, LED luminous tube, fine motion contact button man-machine dialog interface can not satisfy its basic demand.
Along with the develop rapidly of electronic technology, color LCD screen is applied in medical device product widely.Color LCD screen is owing to various, the rich color of its display graphics, and numeral and literal all can show very flexibly, so can show a large amount of figures and Word message.Color LCD screen is enough to satisfy the requirement of existing high frequency electric knife product for bigger demonstration quantity of information.And also has bigger upgrading space.For the medical market in future provides upgrading space to the higher requirement that high frequency electric knife proposes.
The utility model content
Existing charactron, LED luminous tube, fine motion contact button man-machine dialog interface can't satisfy the upgrading product and the renewal of high frequency electric knife because the quantity of information of its demonstration is little.
And the operation of expectation high frequency electric knife is simple, intuitive more.
Make this utility model in order to address the above problem.A purpose of this utility model is to provide a kind of simple to operate, high frequency electric knife intuitively.
Touch screen combines with its contactless and transparent advantage and liquid crystal display screen and can go intuitively to operate the figure and prompting position that liquid crystal display screen provides, and greatly facilitates operator's operation, has reduced the risk that operation mistake is brought.Its contactless advantage has increased its service life again.
Add the touch screen man-machine dialog interface with liquid crystal display screen and replace original charactron, LED luminous tube, fine motion contact button man-machine dialog interface, can satisfy the higher requirement of renewal that the medical market proposes high frequency electric knife.
Therefore, this utility model mainly adopts following two schemes.
Scheme one: the employing liquid crystal display screen adds touch screen module, is connected with main control circuit through the RS232 serial communication interface to reach interactive purpose.
Scheme two: adopt the touch screen signal line to be directly connected to main control circuit and obtain key information; Liquid crystal display screen is connected to main control circuit through the multiplexing parallel bus of address/data.To realize interactive purpose.
Through above two kinds of improvement projects, after original high frequency electric knife product up-gradation, can increase the market competitiveness that ten kinds of mode of operations have improved existing product.
Particularly, this utility model includes but not limited to following proposal.
A kind of high frequency electric knife, wherein, said high frequency electric knife comprises main control circuit, power module, output circuit, the writing of indictments, appeals, etc. and input and display module,
Said main control circuit is connected with said power module, said output circuit and said input and display module, and said output circuit is connected with the said writing of indictments, appeals, etc., and said input and display module comprise touch screen.
Preferably, said input and display module comprise that liquid crystal display screen adds touch screen module.
Preferably, said input and display module add touch screen module through RS232 standard serial communication interface with said liquid crystal display screen and are connected.
Preferably, said input and display module also comprise liquid crystal display screen.
Preferably, the holding wire of said touch screen is connected directly to said main control circuit.
Preferably, said liquid crystal display screen is connected to said main control circuit through parallel address/data multiplex bus.
Preferably, be connected with observation circuit between said main control circuit and the said output circuit.
Preferably, said power module is that said liquid crystal display screen provides 5V voltage.
This utility model adds the touch screen man-machine dialog interface with liquid crystal display screen and replaces original charactron, LED luminous tube, fine motion contact button man-machine dialog interface, can satisfy the higher requirement of renewal that the medical market proposes high frequency electric knife.
