Explanation is further elaborated to a preferred embodiment of the present invention with reference to the accompanying drawing, in the preferred implementation side
In formula, two channels are only included.It should be noted that it is only for for example, the present invention is not limited thereto.
The invention discloses a kind of double channels microwave ablation systems, support two ablation needles while being melted.The microwave
Ablation system is made of microwave generator and microwave ablation attachment.Microwave generator by two groups of microwave power units, power module,
The composition such as main control unit, display unit, fan system, cooling water pump, external interface, as shown in Figure 1.
As shown in Fig. 2, each microwave power unit includes signal source, voltage-controlled attenuator circuit, power amplification link, power coupling
Clutch, circulator, temperature detection, sub-control unit, power-sensing circuit, sub- communication unit etc..Low-power is generated by signal source

Power-sensing circuit can detecte the power of microwave power unit output and the relative value of port reflection power.Sub-control unit
Bias voltage is generated by automated power control algorithm, is loaded on voltage-controlled attenuator, makes microwave power output unit output work
Rate is consistent with user setting.Its specific algorithm is shown in Fig. 3.
Wherein, the variable that sub-control unit can control includes:
1. power relative value P1(being obtained by power-sensing circuit)；
2. user sets performance number P0(being obtained by sub- communication unit)；
3. calibration of power coefficient f1(being obtained by subsystem memory)；
4. the bias voltage V of voltage-controlled attenuatorp(being generated by sub-control unit).
The process that the sub-control unit automatically controls is as follows:
The power relative value P that sub-control unit is obtained based on power-sensing circuit1, and it is single from control by sub- communication unit
The user obtained at member sets performance number P0To calculate Δ P, calculation formula are as follows:
Δ P=P0-P1×f1；
Wherein, f1The calibration of power coefficient f obtained for subsystem memory1。
Value based on Δ P is greater than, equal to being also less than 0, and sub-control unit generates the biasing of corresponding voltage-controlled attenuator
Voltage Vp, and be fed back to voltage-controlled attenuator and pad value is adjusted.

Microwave power unit is also equipped with power monitoring and temperature-monitoring function.When power monitoring circuit or temperature monitoring unit
When monitoring reflection power or internal temperature exception, sub- communication unit feeds back to main control unit, and main control unit stops immediately
Microwave output, and issue the user with prompt or alarm.
Main control unit can make each microwave power unit send out of phase with each microwave power unit of coordinated control
Constant amplitude microwave power.Using the principle of interference of electromagnetic wave, electromagnetic wave can be focused on to feature region, carry out relevant ablation.
As shown in figure 4, working as the pi/2 more advanced than 1 phase of microwave power unit of microwave power unit 2 (1/4 period), and corresponding two ablations
When antenna distance is λ/4 (λ is the wavelength that microwave is propagated in the tissue), the electromagnetic wave that two ablation antennas emit is in left side
Region opposite in phase, coherent subtraction are cancelled out each other；It is concerned with and increases in right area electromagnetic wave phase identical (difference number of cycles)
By force, it is overlapped mutually.Therefore microwave energy focuses on right area.If right area is melted using traditional single needle, due to list
Needle zone of ablation is symmetrical relative to ablation needle, then entering pin position will certainly be close from diagram blood vessel, is easy to pierce blood vessel；And it is double
The method of the relevant ablation of needle can then avoid blood vessel.Using multichannel, connects more microwave melt needles and carry out the relevant of N number of unit

Cooling water circulates in dynamic cooling water pipe.Under single pin mode, the cooling water connector 3 of microwave needle is directly connected to cooling water pipe
On；Under dual pin mode, cooling water pipe is connected by two threeway adapters with two ablation needles 1, and (two 1 water routes of ablation needle are simultaneously
Connection), as shown in Figure 6.Compared with water route series system shown in Fig. 7, water route parallel way more can effectively cool down two ablations
Needle 1.Because first, cooling water is heated in first ablation needle 1 and enters back into second ablation needle 1 in the series system of water route,
It is poor to will lead to second 1 ablation effect of ablation needle, temperature is high；Second, water route parallel way is smaller than the resistance of water route series system,
Flow is big.
Under dual pin mode, after setting the power in a channel, when resetting the power in another channel, microwave generator
Main control unit can be settable according to the power automatic limiting routing in channel one maximum power two, to guarantee the output of two channels
The sum of power is no more than the power limit of safety.
Inside ablation needle and outer surface is respectively equipped with a thermocouple, separately detects internal cooling water temperature and outside organization
Temperature accesses microwave generator by signaling interface (Fig. 5,6), and microwave generator main control unit is according to collected temperature pair
Ablation needle carries out protection and temperature control.When cooling water recirculation system exception, when causing ablation needle internal temperature excessively high, microwave generator
It can stop microwave output immediately, and alarm.Before surgery ablation temperature can be arranged, when disappearing according to patient tumors situation in user
Be ablated to during melting after tissue temperature reaches set temperature, microwave generator can adjust automatically output power, make tissue temperature
Stablize in set temperature.In this way, ablation system can guarantee that ablation procedure is safe, controllable.
In addition, the above-mentioned definition to each element and method is not limited in the various specific structures mentioned in embodiment, shape
Shape or mode, those of ordinary skill in the art simply can be changed or be replaced to it, such as:
(1) the water route connection under dual pin mode can also be connected using series connection water route shown in Fig. 7, it is preferred to use Fig. 6 institute
