Description
The present invention relates to a kind of main treatment tumor treatment instrument, belong to medical equipment.
At present, whole world cancer mortality has accounted for second of dead sum, though various countries utilize modern science and technology to capture cancer, but the most direct for preinvasive cancer from present treatment means, method is recommended excision by general acclaim the most completely, but because tumor is excessive, reasons such as the position is improper only have the sub-fraction cancer can implement excision, and recurrence after operation rate height.Therefore the local treatment of development operation becomes the clinical pressing issues that face.Features such as and now countries in the world are developed in succession and utilized microwave to make therapeutic equipments, utilize the thermal efficiency of microwave good, and heat radiation is uniform and stable cover tumor, and make its coagulation necrosis, kill cancer cell.But there is following defective in existing micro-wave therapeutic instrument: 1. heating-up temperature is difficult to control, when microwave heating burns out cancerous cell good on every side tissue is burnt out; 2. the cancerous issue carbonization of solidifying makes surrounding tissue can not effectively absorb microwave energy; 3. the microwave heating bar stretches into to organize and is prone to the surrounding tissue adhesion in the heating process or forms the phenomenon of sinus tract, the wound that causes suffering and be difficult to heal to patient.
The objective of the invention is to design a kind of temp-controllable microwave radiator of cancers, it is rational in infrastructure, is easy to the controlled microwave heating-up temperature, the adhesion surrounding tissue.
The designed temp-controllable microwave radiator of cancers of the present invention mainly is made of handle, joint, radiation under, have power input seat and thermometric seat on the handle, be connected by joint between handle and the radiation under, coaxial cable is installed in the radiation under, be wound with active antenna in its end, the end of active antenna and coaxial cable is connected, coaxial cable in the radiation under is with the critesistor shielded-plate tube, critesistor wherein is installed, critesistor is connected with the thermometric seat, coaxial cable is connected with power input seat, and the body of rod of radiation under has the politef cover.
The critesistor of the temp-controllable microwave radiator of cancers that the present invention is designed is 5～50mm apart from the distance of radiation under end.
The length range of the active antenna in the designed temp-controllable microwave radiator of cancers of the present invention is at 5～200mm.
Active antenna in the designed temp-controllable microwave radiator of cancers of the present invention is a spiral type, and its spacing is at 0.1～10mm.
The material of the active antenna in the designed temp-controllable microwave radiator of cancers of the present invention is the metal or alloy silk, and the diameter of silk is between 0.05～1mm.
The coaxial cable appearance of the temp-controllable microwave radiator of cancers that the present invention is designed has the teflon insulation cover.
The active antenna of the temp-controllable microwave radiator of cancers that the present invention is designed by resistivity (ρ) between 0.2～2.
The standing-wave ratio of the active antenna in the designed temp-controllable microwave radiator of cancers of the present invention is in 1.4～3 scopes.
The designed temp-controllable microwave radiator of cancers of the present invention is connected radiation under rear portion thermometric seat by microwave cable when using with the temperature control instrument, power is imported and is connected with the power loader.Cancerous tumours inside is inserted in the end of the radiation under of irradiator, and by the outside launched microwave heat temperature raising of microwave antenna, the big as far as possible solidification zone that forms in cancerous tumours makes the cancerous issue necrosis.But, make solidification zone not produce carbonization because its temperature by the temperature control instrument monitoring, therefore can be controlled Heating Zone Temperature effectively.Heat and took out radiation under in about 5 minutes,, do not have adhesion with surrounding tissue because the body of rod of radiation under has the politef cover, when therefore taking out radiation under, the adhesion surrounding tissue, wound is easy to healing.
The advantage of the temp-controllable microwave radiator of cancers that the present invention is designed is:
1. compact conformation, reasonable in design, Controllable Temperature is built in below 69 ℃, from Fig. 4 C figure can find out temperature be elevated to 65 ℃ near the time, therefore the maximum gauge that solidifies does not change with heat time heating time and power, solidifies cancerous tissue in the maximum magnitude under the situation that can not produce carbonization, and can implement multiple spot solidifies, every maximum solidification temperature is in full accord, and every spheric solidification zone size of class is the same, promptly can kill cancerous issue effectively to greatest extent.
2. do not produce adhesion, the designed active antenna input power of the present invention can reach in 30W～40W scope and form the heats that the spherical maximum gauge of class solidifies, can find out by B figure among Fig. 4, input power is big again, its heating-up temperature can not rise yet again, therefore the heat that radiation under distributed is little, and because the radiation under skin is the housing of cohesive material not, can carbonization to organizing not around the body of rod of radiation under, adhesion, misery when reducing patient makes treatment back patient's wound be easy to healing.
3. effective percentage height.
The designed temp-controllable microwave radiator of cancers of the present invention mainly is applicable to organa parenchymatosum's cancerous tumours, also can be used for others.
