Abstract
The invention discloses a microwave ablation system. The microwave ablation system is mainly characterized in that by utilizing a phased array technology, microwave is focused in a specific position in vivo so as to cause coagulative necrosis of a tumor tissue or a pathological change tissue within short time. Compared with other microwave ablation systems at home and abroad, the microwave ablation system has a noinvasive characteristic. The whole system consists of an upper control computer, a communication bus, a multi-channel microwave transmitter and a transmitting antenna array.
Description
Technical field
The present invention relates to a kind of micro-wave therapeutic instrument, relate in particular to a kind of microwave ablation system based on phased-array technique.
Background technology
In the bio-tissue, microwave energy makes biological tissue's Semi-polarity molecule and ion produce heat energy by frictional impact in alternating electric field.Can use microwave to treat tumor based on this principle people.Microwave ablation technology treatment tumor is a kind of less invasive techniques of rising the nineties.It is under image (ultrasonic, CT etc.) guiding, the micro-wave therapeutic pin is accurately inserted in body tumor tissue or the pathological tissues, by the micro-wave therapeutic pin microwave energy is sent in the tissue, produce the high temperature of 60-120 degree Celsius, make tumor tissues or pathological tissues produce coagulation necrosis at short notice, thereby reach therapeutic purposes.But this microwave ablation method, the micro-wave therapeutic pin that must place some at the pathological tissues place is a microwave antenna, the quantity of placement is by the decision of tumor tissues size.
Summary of the invention
The objective of the invention is is providing a kind of micro-wave therapeutic pin of not placing, the microwave energy of certain intensity also can a certain in vivo position be provided, makes tumor tissues or pathological tissues produce a kind of microwave ablation system of coagulation necrosis at short notice based on phased array.
This system adopts beam-forming technology based on phased-array technique, realizes that ad-hoc location focuses in vivo.The frequency of each the radiating circuit passage in this system, amplitude and phase place are controlled respectively, have higher emission effciency, and each interchannel high conformity.
The technical solution used in the present invention is as follows:
Whole system has comprised control host computer, communication bus, multichannel microwave transmitter and launching antenna array composition.
The present invention compares with the traditional microwave ablation system, owing to adopt beam-forming technology, realizes that ad-hoc location focuses in vivo.Avoid the contact pin operation of traditional method, avoided the possibility of postoperative infection.
Description of drawings
Fig. 1 is a structure chart of the present invention
Fig. 2 is the Pareto diagram of the described aerial array among the present invention
Among the figure: the 1-host computer, the 2-communication bus, 3-multichannel microwave transmitter, the 4-launching antenna array, the 5-transmitting antenna is described further below in conjunction with embodiment and accompanying drawing thereof.
Embodiment
As shown in Figure 1, native system is by host computer 1, communication bus 2, multichannel microwave transmitter 3, and launching antenna array 4 constitutes, and it is characterized in that:
Described transmitting antenna array 4 comprises MxN transmitting antenna, wherein recommends 32 of 4x in the present embodiment.Described transmitter comprises MxN,, wherein recommend 32 of 4x in the present embodiment.Port number can be many in the system, and the many more infringements to other normal structure of passage are more little, but the control corresponding complexity increases.
Work process of the present invention is as follows: at first by the Medical Imaging mode, as nuclear magnetic resonance, obtain tumor tissues or pathological tissues in the intravital position of sufferer, and set different electrical parameters according to the different tissue in cross section, obtain each passage emission parameter at last.
Set the parameter of each transmission channel in host computer 1, as frequency, phase contrast, amplitude etc., by communication bus 2 these parameters are sent to multichannel microwave transmitter 3, microwave transmitter 3 sends to launching antenna array 4 to energy.Each transmitting antenna is realized focusing on according to the Phase delay that configures, and makes the tumor tissues of focal spot or pathological tissues produce coagulation necrosis at short notice.
The present invention is not limited in the foregoing description, and providing under the technical conceive in claim to have multiple structural change, can be designed to as launching antenna array 4 square, be convenient to the design.
Claims (3)
