Description
Technical Field
The utility model discloses a two switch circuit of two power amplifiers of high frequency electrotome belongs to medical electrotome control circuit's technical field.
Background
The high-frequency electric knife is a point surgical instrument for replacing a mechanical scalpel to cut tissues, and the high-frequency (usually 200kHz to 3MHz) high-voltage current generated by the tip of an effective electrode is used for heating the tissues when contacting with a body, so that the separation and coagulation of the body tissues are realized, and the aims of cutting and stopping bleeding are fulfilled.
In the technical field, the conventional high-frequency electrotome surgical device has a single function, namely only a single knife pen can be used, and the current clinical requirements are difficult to meet.
In contrast, the art also discloses many relevant patent documents, such as:
chinese patent documents: CN205831903U a surgical energy platform system provides a surgical energy platform system comprising: a plurality of surgical instruments; an energy supply device; a power controller; the power controller has a plurality of energizing modes for causing the energizing means to energize one of the plurality of surgical instruments in different energizing modes; the display control unit is used for displaying the current energy supply mode and energy supply mode information of the power controller; the control switch is used for switching the energy supply mode of the power controller; and is used for sending a switching signal; and the control system is used for receiving the switching signal and controlling and switching the energy supply mode of the power controller according to the switching signal. It can be seen that this patent document is only for the purpose of switching between the use of a plurality of functional instruments, and therefore only uses a control switch for switching the functional mode of the power controller, however, the apparatus still uses a power supply device for only a single surgical instrument. Many medical institutions with scale often purchase multiple high-frequency electrotome surgical devices to prevent unnecessary medical accidents caused by sudden failure of a single device during surgery. However, in the basic medical institution, it is difficult to purchase a plurality of spare units at the same time because of the great equipment value.
U.S. patent document publication US4188927A discloses a multi-source electrosurgical generator in which one source may be optimized for desiccation of patient tissue, another source may be optimized for electrocautery thereof, and a third source may be optimized for cutting. All sources operate in a common output circuit and may be driven individually or in combination. The source may also be operated in only dry, electrocautery and cutting modes of operation. The different operating modes may be selected from a hand-held electrosurgical instrument. Insulated, split patient electrodes may be used with the generator in cases where the frequency of operation of the drying source may be higher than the frequency of operation of the arc or cutting source. The spark detection circuit may also be used to (a) ensure electrocautery when the active electrode is a needle, (b) prevent neuromuscular stimulation, and (c) ensure continuity of the patient's circuit when electrocautery is run with low levels of current. Therefore, although the patent document has a plurality of function modules, each function module only corresponds to a single source, and the function of outputting a plurality of sources simultaneously is realized, because the function modules correspond to the sources one to one, when one function module is damaged, the corresponding function source fails, and a doctor can only use two sources for outputting simultaneously at most one by one hand, so that the added function modules greatly increase the equipment cost. And since the functional module cannot switch outputs in the case of using a single source, its lifetime is reduced.
Because the traditional knife pen can only treat a single part by using a single functional mode, different functional modes can be required to be used for treatment simultaneously under a double-part injury mode to achieve the operation effect. The single working mode is adopted, and the injured parts cannot be treated simultaneously, so that the treatment of the patient is possibly delayed, and the patient cannot achieve the optimal treatment effect. Even if two machines are working at the same time, a single main physician cannot operate the machines alone and the use cost and the indoor space are increased.
In view of this, in the technical field, how to improve the high-frequency electrotome, so that a single device can output multiple frequencies and functions simultaneously, and the technical problem to be solved in the field is to switch a normal working unit in time to realize safe replacement work when a single unit fails.
