Description
Technical field
The present invention relates to medical instruments field, relate in particular to electric medical apparatus and instruments.
Background technology
At present, electric medical apparatus and instruments has obtained using widely at medical field.The electricity medical apparatus and instruments generally includes main frame and the adnexa that is connected with main frame, and wherein, main frame is used for providing electric flux output, and adnexa can be therapeutic device (for example, electric knife head, electric clamp etc.), also can be other functional parts (for example, manual switch etc.).A main frame can connect the adnexa of number of different types usually, for fear of the wrong adnexa of user grafting, often need main frame can identify the type of the adnexa of pegging graft, can carry out alarm with the apparatus main frame that mistake is pegged graft, whether the type that perhaps shows institute's grafting adnexa for user is the adnexa of oneself thinking usefulness so that user is understood what peg graft.
The method that known identification electricity medical apparatus and instruments is attached the part type has multiple.A kind of mode is to have placed nonvolatile memory (EEPROM) in the therapeutic device plug, has preserved the information of apparatus type in memorizer, and apparatus is with after main frame is connected, and main frame reads the EEPROM internal information can distinguish the apparatus type.But it has three subject matters: at first, main frame must be supplied working power to memorizer during to the read operation of EEPROM, in addition, also data connecting line will be arranged, and it is many therefore to connect the additional connecting line of socket; The second, when main frame output high-frequency energy, the data that read of EEPROM are easy to be subjected to high frequency radiation and disturb and make a mistake, and are difficult to correctly confirm and identification apparatus information.
Another kind of mode is to utilize the magnetic encoding and decoding technique, makes at plug to have the magnetic powder material of magnetic property, and the host socket place arranges the magnetic stripe reading device, can read the magnetic stripe encoding information.The problem of this mode is: on the one hand, the read operation of magnetic information is subject to the strong high frequency output radiation influence of main frame and produces mistake; On the other hand, high frequency radiation magnetic field can make the magnetic powder material remagnetize, causes this information permanent error; In addition, beyond thought problem also can be caused in magnetic field in uncertain working environment or the storage environment, makes the application of this technology in electrosurgery unit also very difficult.
Also having a kind of mode is to utilize optical principle, optical transmitting set and optical receiver are set in the socket of main frame, normal condition, receptor can receive the emission light beam of emitter, when the apparatus plug insertion socket, whether light path is cut off, and receptor can't receive light beam, differentiate socket successively and insert.The problem of this mode is: at first, can only simply realize the differentiation whether plug inserts, can't realize the apparatus type identification; The second, on the structural design, need strict guiding frame for movement, the making of interface acquires a certain degree of difficulty.
Also having a kind of mode is to utilize radio transmission to receive principle, configuration information memorizer and transmit receive antenna in plug, and when receiving the electric wave of main frame emission, plug postbacks electromagnetic wave by this electric wave energy and gives main frame, and storage information is sent.Similarly, when main frame output high-frequency energy, can produce strong frequency electromagnetic waves, therefore disturb the radio communication effect between plug and main frame, perhaps can not read the information of apparatus, perhaps read information errors.
Some method has the encoding and decoding treatment technology of more tight signal processing and safety, reads information and generally can not make a mistake.Though utilized the digital conversion technology, obviously, very sensitive receiving device makes the communication electromagnetic wave still very easily be subjected to the high-frequency electromagnetic wave interference of main frame output, the minimizing of error probability, cost be can't sense information probability can increase greatly.It also is not suitable for the application of the electrosurgery unit of high-frequency energy output.
Also having a kind of mode is the photoelectric coding technology, is provided with the sensor of infrared transmitter and receptor at the socket of master controller.Optical sensor one side at the close socket of apparatus plug is printed on corresponding black coded markings, each coded markings position receives path over against corresponding light emission, if this position does not have labelling, then the light beam of luminous tube emission produces reflection herein, be subjected to optical sensor can receive reflected light, there is density bullet then can absorb the infrared beam of luminous tube, is subjected to optical sensor will not receive folded light beam.So just formed one " 0 " and " 1 " digital coding, dispose manyly to such sensor, then formed multidigit and encode.The encoding and decoding of obvious this photoelectric technology need many to the photoelectricity photoelectric sensor, and the structure more complicated has limited its application on armarium.
On the other hand, user needs also to know whether adnexa is intact with being connected of main frame, for example, perhaps can exert oneself during operation excessive plug to be pulled out and Offhost, therefore needs the main frame connection status of detection accessory and main frame in time.
And the electric medical apparatus and instruments that has need be in operation process be controlled the level of electric flux output, and these controls usually will be at the enterprising line operate of main frame, if but can realize in the therapeutic device drilling, will provide great facility for user.
