Abstract
A puncture needle for RF therapy features that a RF probe is connected to one end of fine metal rod, whose another end is connected with the RF electrode in telescopic handle, and an operating handle sleeves around the said telescopic handle. Its advantages include great radiation surface for higher curative effect, and low radiation impedance for higher therapeutic energy.
Description
The present invention relates to a kind of medical apparatus and instruments when being used for tumor in the radio frequency interventional therapy human body, particularly relate to a kind of as the anodic puncture needle of radio-frequency transmissions.
At present, in radio frequency interventional therapy field, various puncture needle for RF therapy can form various change procedures.A common radio-frequency (RF) therapy process comprises that implantation, the radio-frequency (RF) energy for the treatment of puncture needle import, tissue is subjected to thermal coagulation and treats withdrawing from of puncture needle.In order to form this process, need a puncture needle for RF therapy as treating anode and a larger area conducting plate at least as the treatment negative electrode, surround point of care thereby set up effective radio frequency electromagnetic field.And the most complex structure of existing various puncture needle for RF therapy, cost is comparatively expensive.
The purpose of this invention is to provide and a kind ofly can effectively overcome above-mentioned defective, rational in infrastructure, the puncture needle for RF therapy that resultant effect is good.
Technical solution of the present invention is, a kind of puncture needle for RF therapy, mainly form by the thin bar of metal, operating grip, telescoping handle, rf probe and radio-frequency electrode, its characteristics are: an end of the thin bar of metal is connected with a rf probe, the other end links to each other with radio-frequency electrode in placing telescoping handle, and telescoping handle is with operating grip outward.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion novel structure of the present invention, be skillfully constructed, formed a very big radiating surface, can surround point of care better thus, and making that the shape of radio frequency electromagnetic field more becomes rationally around the point of care, heats is better; Simultaneously, bigger radiating surface helps reducing radiation impedance, increases the radio-frequency (RF) therapy energy, the tissue of area for treatment that can condense more effectively like this, tool promotional value.
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is a structural representation of the present invention.
Among the figure, the front end of rf probe 1 is made by elastomeric metal material, and front end can be the Flos Chrysanthemi shape to launch, and the other end is welded on an end of the thin bar 2 of metal.The thin bar 2 of this metal provides the effect of radio-frequency current path in addition except that fixed RF probe 1.The metallic whorl brace rod 7 that the other end and of the thin bar 2 of metal has international thread is connected with welding manner.The female thread engagement of the external screw thread of whorl brace rod 7 and radio-frequency electrode 8.The radio-frequency power supply that the radio-frequency power supply device provides is introduced by radio-frequency electrode, is sent to rf probe 1 through above-mentioned parts, to set up the radio frequency electromagnetic field that treatment needs; The rf probe 1 outer metal canula 3 that front end is provided with the puncture acute angle, the metal canula 3 outer plastic bushings 4 that are with of being with.The puncture acute angle of metal canula 3 can pierce through peripheral organizations such as skin, and rf probe 1 is delivered to predetermined area for treatment.And the main uses of plastic bushing 4 is tissues of isolating metal sleeve pipe 3 and non-area for treatment, makes the latter can be not injured because of the heat of contacting metal sleeve pipe 3 and electricity.Wherein, radio-frequency electrode 8 is to be positioned at telescoping handle 6, the telescoping handle 6 outer operating grips 5 that are with.Rf probe 1 is along with telescoping handle 6 moving and open or be hidden in the metal canula 3 in operating grip 5.
Claims (3)
1, a kind of puncture needle for RF therapy, mainly form by the thin bar of metal, operating grip, telescoping handle, rf probe and radio-frequency electrode, it is characterized in that: an end of the thin bar of metal is connected with a rf probe, the other end links to each other with radio-frequency electrode in placing telescoping handle, and telescoping handle is with operating grip outward.
2, by the described a kind of puncture needle for RF therapy of claim 1, it is characterized in that: rf probe is with the metal canula that front end is provided with the puncture acute angle outward, and metal canula is with plastic bushing outward.
