Abstract

The utility model provides an electrode with a protecting device for an external radio-frequency prostate therapeutical instrument, which is characterized in that the lower protective plate of the electrode is added with protective nails. The positions of the bodies of patients and the electrode can be limited during the processing of long time treatment, so that the skin of the patients can not be in the position approaching to the electrode plate where the high-frequency current density is extremely high and can not be burned. The therapy is more safe and reliable, and the course of therapy is more harmonious and easy to reach better therapeutic effect.

Description

The electrode that is used for external radio-frequency therapy apparatus for prostate gland with protector

This utility model belongs to medical electronic Instrument technology field, particularly external radio-frequency therapy apparatus for prostate gland.

As everyone knows, external radio-frequency therapy apparatus for prostate gland is the new instrument of the treatment person in middle and old age prostatosis that gets up of developed recently, and it is easy to treat, no pain and good effect and welcome by the patient.There are the neat electronic medical instruments factory in east, Shanghai Communications University and University of Electronic Science and Technology etc. in the unit of the external medical apparatus for treating prostatic diseases of domestic existing production; the electrode that they use generally all adopts circular metal plate; its outer baffle that all has insulant to make, and link to each other with the output matching circuit of radio frequency source by plain conductor.During treatment, on, bottom electrode position relative fixed, the patient is in as medium, between the bottom electrode, on, on the bottom electrode aligning patient prostatic, the below, when adding radio-frequency voltage, produce the effect that heat reaches the treatment prostatosis at patient's prostate place, its common treatment time was generally each 30 minutes～2.5 hours, in this long treatment time, though the patient lies on the treatment frame, but on its health is not understood unavoidably, mobile or left down, the right side is stirred, this will make skin of abdomen directly touch top crown, this will be because of near the too high patient skin of burning of the high frequency electric density battery lead plate, and for the patient causes new misery, and operator's thought also is in state at full stretch.

At the problem of therapeutic instrument electrode, the purpose of this utility model is to propose a kind of electrode with protector of new construction, and the skin burn that causes when preventing to treat makes treatment safer, reliable.

The structural representation of the electrode with protector that is exclusively used in external radio-frequency therapy apparatus for prostate gland that this utility model provides as shown in Figure 1.It is that round metal pole plate 1 is placed on the electrode that insulant makes under the baffle 4 and electrode between the baffle 5; entelechy plate 1 links to each other with the match circuit of therapeutic instrument by plain conductor 2; be with sheath rod 3 on the plain conductor 2; and link to each other with baffle 4 on the electrode, at least 1 protection nail 6 of being made ganoid cylinder body shape by insulant is arranged on the baffle 5 under the electrode.

Baffle 5 and sheath rod 3 adopts under baffle 4, the electrode on its electrode insulant should be the high-frequency dielectric loss low such as materials such as polyethylene, politef, polyformaldehyde.

The dielectric constant that its protection nail 6 used insulant should be selected its dielectric constant and air for use close such as politef, polythene material etc., with regard to not influencing upper and lower interelectrode Electric Field Distribution, promptly can not change the treatment temperature like this because having increased the protection nail on the electrode; The length of its protection nail should not worked energetically the treatment distance between electrode and the human body, otherwise therapeutic effect will weaken greatly or just do not had the treatment meaning at all; The diameter of protection nail is not too small, otherwise be not easy to processing, also easily lose, if it is too thick, too many, when it takes under the entire electrode baffle 5, promptly be the thickness that has entirely increased baffle, this is with the weight of excessive increase entire electrode, for electrode fixedly bring difficulty, also increased the cost of electrode simultaneously; The nail body of protection nail should be ganoid cylinder, and such as cylinder, hexagonal prism etc., its protection nail end should be slick such as spheroid, feels comfortable when making the contact human body skin, and the unlikely skin of stabbing; Protection nails on and has groove, to increase the distance of discharge, can prevent the space discharge.

Behind the electrode that external radio-frequency therapy apparatus for prostate gland employing this utility model provides with protector, both made in the long period treatment, patient's body is left and right, upper and lower when mobile as having slightly, the protection nail will contact with patient's abdominal part, thereby define the position of patient body and electroplax, human body skin can not burnt because of high frequency electric density is too high, make treatment safer, reliable; The operator does not need to dig-in the patient, and patient's the frightened heart also alleviates, and makes therapeutic process more with harmonious light, reaches better therapeutic effect.

Fig. 1 this utility model structural representation

Among the figure: 1 round metal battery lead plate; 2 plain conductors; 3 sheath rods;

Baffle on 4 electrodes; Baffle under 5 electrodes; 6 protection nails.

Embodiment:

In conjunction with Fig. 1, this utility model done specifying:

Electrode plectane 1 adopts red copper to make; Baffle 5 employing polythene materials under baffle 4, the electrode on sheath rod 3, the electrode, and the protection nail adopts politef to make; 2 protection nails are arranged, the length L=30mm of each nail, diameter phi=20mm nails on and has a groove, and the nail body is a cylinder, and the nail termination is a hemisphere.

Claims (3)

1, being used for the electrode that external radio-frequency therapy apparatus for prostate gland has protector comprises: round metal pole plate (1) places on the electrode that insulant makes under the baffle (4) and electrode between the baffle (5); round metal pole plate (1) links to each other with the therapeutic instrument match circuit by plain conductor (2); be with on the plain conductor (2) sheath rod (3) and with electrode on baffle (4) be connected to form the ganoid cylindricality protection nail (6) that it is characterized in that having on the baffle under electrode (5) at least 1 insulant to make.

2, according to the electrode that external radio-frequency therapy apparatus for prostate gland has protector that is used for of claim 1, it is characterized in that described protection nail (6) is the ganoid cylinder that adopts dielectric constant to make near the insulant of dielectric constant of air, is carved with groove on its cylinder; The cylinder termination is slick spheroid; The length of its protection nail should be not more than the treatment distance between electrode and patient.

3,, it is characterized in that baffle (5) and sheath rod (3) all adopt the low material of high-frequency dielectric loss to make under baffle on the described electrode (4), the electrode according to the electrode that external radio-frequency therapy apparatus for prostate gland has protector that is used for of claim 1.
