Abstract
A kind of microwave radiometer that is suitable in the use of narrow positions such as human oral cavity, its radiation head adopts needle-like radiation head, can produce " 8 " around radiation head, and the microwave radiation energy of font directional diagram has characteristics simple in structure, that therapeutic effect is good.
Description
The present invention relates to a kind of device that is used to radiate treatment, particularly relate to the microwave radiometer that usefulness is disposed in a kind of near field.
China's utility application discloses a kind of Y type microwave radiator uterine cavity for No. 89210596.8, this irradiator is made up of the signal input connector, coaxial line and the radiation head that join with the microwave therapy apparatus signal source, the two ends of coaxial line are connected with radiation head with signal input connector respectively, its radiation head is the Y-shaped radiation head with expansion circlip, is convenient to use in the human body uterine cavity.But at the more tiny narrow position of human body, as human oral cavity, above-mentioned Y-shaped radiation head obviously is inapplicable.In addition, in some oral disease of treatment, during as periapicalitis, both require radiation head can insert in the root canal, required in tip of a root surrounding tissue to form the suitable microwave radiation space of intensity that the concentration of local and the degree of depth should not dark excessively (crossing the dark normal structure that then can influence the deep) again.In such cases, above-mentioned existing irradiator more can not satisfy the treatment requirement.Therefore, for micro-wave therapeutic is implemented at the tiny position of human body, having to have to provide a kind of new microwave radiometer.
The objective of the invention is the radiation head of above-mentioned existing irradiator is improved, a kind of oral cavity microwave radiator of being convenient to treat oral disease is provided.
Oral cavity microwave radiator of the present invention has signal input connector, coaxial inner and outer conductor and radiation head, has insulator between the coaxial inner and outer conductor, and outer conductor is provided with opening, and the inner wire end is connected by this opening conduction with radiation head.In the present invention, especially the shape of radiation head is chosen to be needle-like.The needle-like radiation head not only is convenient to insert the tiny narrow position of human body and is used, and it can constitute the microwave radiation space of figure of eight directional diagram, and can not produce stronger microwave energy on the needle point direction when work around the needle-like radiation head.This point requires the unsuitable excessive occasion of the penetration depth of microwave on the radiation head direction of insertion again for both requiring radiation head to insert, and the treatment as periapicalitis has more special significance.Clinical Practice proves that in the microwave radiation space of figure of eight directional diagram, the heat effect of microwave energy and non-thermal effect have the excellent treatment effect to the human lesion tissue around the needle-like radiation head, are particularly useful for using in human oral cavity.
Oral cavity microwave radiator of the present invention is compared with above-mentioned existing Y type microwave radiator uterine cavity, has characteristics simple in structure, as to be convenient to use in narrow positions, can produce pathological tissues around the needle-like radiation head better curative effect.
Content of the present invention further illustrates with the following Examples, but content of the present invention is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of oral cavity microwave radiator among the embodiment.
As shown in Figure 1, the oral cavity microwave radiator in the present embodiment has coaxial line 1, column inner wire 3, insulated handle 7 and needle-like radiation head 11.Have the insulating barrier 5 that is made of politef between the inner wire 2 of coaxial line and the outer conductor 4, coaxial line 1 is fixed on the handle 7 by screw 8 and briquetting 9.One end of coaxial line is a signal input connector 6, and the other end of coaxial line is a signal output part.At the signal output part of coaxial line, coaxial inner conductor 2 stops at one segment distance place, distance outer conductor 4 ends, and is connected with the end conduction of column inner wire 3.The other end of column inner wire 3 is the link with needle-like radiation head 11.In the present embodiment, coaxial inner conductor 2 and column inner wire 3 common formation irradiator inner wires.For satisfying the requirement of impedance matching, outer conductor 4 has the gradually section of opening near the junction point of coaxial inner conductor 2 and column inner wire 3.Outer conductor 4 stops in the radiation head link place of column inner wire 3, and column inner wire 2 promptly realizes that by the opening of outer conductor end conduction is connected with needle-like radiation head 11.For ease of in use radiation head being changed and disinfected, the present invention is provided with the radiation head connecting interface that matches with needle-like radiation head afterbody at the radiation head link of column inner wire.Connecting interface in the present embodiment also is correspondingly provided with the helicitic texture that matches with this hickey for the interface 10 that is threaded, radiation head afterbody.Screw-type interface 10 among the embodiment is also available realizes that with the radiation head afterbody friction tight plug-in type interface replaces.In order to obtain better therapeutic effect, the length of needle-like radiation head adopts λ/4 in the present embodiment.Herein, λ is for leading interior wavelength.
Irradiator in the present embodiment has been done the clinic trial of treatment periapicalitis at Stomatology Medicine College, Huaxi Medical Univ.Irradiator is when treating work, and the voltage standing wave(VSW) coefficient that records from signal input connector 6 is less than 2.5.When irradiator in treatment during work, its voltage standing wave(VSW) coefficient is further less than 2.Show promptly and controlling under the dental phenomenon that irradiator can send out microwave energy effectively to needle-like radiation head surrounding space, produce heat effect and non-thermal effect, reach bactericidal anti-inflammatory effect preferably at the tooth tip of a root.In clinic trial, through the patient of micro-wave therapeutic periapicalitis totally 30 examples, wherein in the 18 routine root pipes exudate is arranged, through 1-2 micro-wave therapeutic, promptly there is not exudate.Other 12 examples are kowtowed pain disappearance person 6 examples for kowtowing pain apex of root of tooth week after treatment once, other 6 examples are kowtowed pain in the second time and disappeared behind the micro-wave therapeutic.Above situation shows, the treatment of oral cavity microwave radiator of the present invention, sterilization, antiinflammatory effect are remarkable, can shorten the healing course of treatment of dental disorder significantly.
