Description

[Detailed description of the invention] (a) Industrial application field This invention relates to an applicator in a capacitive type biological treatment device, and particularly relates to a feeder connection mechanism.

(B) Prior Art Generally, some living body treatment devices are designed to apply high frequency energy to a living body to examine or treat that living body. This capacitive type biological treatment device is equipped with an applicator consisting of a pair of electrode bodies each connected to a feeder, and the pair of electrode bodies are brought into close contact with the heated part of the living body to apply high frequency energy. Thus, the heated portion is heated.

(c) Problems to be solved by the invention In the applicator for the biotherapeutic device described above, a plurality of continuous pieces are arranged in parallel at a predetermined interval between both feeders, and both feeders are positioned parallel to each other. configured to supply power.

However, this has the disadvantage that only one of the electrode bodies cannot be replaced because both feeders are connected and fixed as one body. That is, although electrode bodies of the same shape are usually paired, it may be desired to use electrode bodies of different shapes depending on the part to be heated. In this case, conventionally it was not possible to replace only one electrode, so the entire applicator had to be specially manufactured.

In addition, even if one electrode body breaks down, the entire applicator must be replaced, and since the length between both feeders is kept constant, the length between both electrode bodies is also constant. The drawback was that it was difficult to use.

(d) Means and action for solving the problem This invention is a biological treatment device that applies high frequency energy to a heated part of a living body to heat it. A feeder is connected to each electrode body, and a connecting body is provided in the middle of both feeders to connect both feeders, and this connecting body connects a pair of base pieces with an engaging part and an engaged part. One end of this base piece is connected to the feeder, and an engaging part and an engaged part are formed to be detachable, so that both feeders can be freely approached and separated, and both feeders are connected to each other. The electrode body is configured to have a variable length, and can be replaced together with one electrode body and the feeder.

(E) Examples Examples of this invention will be described below based on the drawings.

As shown in FIGS. 1 to 5, 1 is an applicator in a biological treatment device, which is attached to a heated part of a living body (not shown) and applies high-frequency energy to the heated part. , configured to administer thermal therapy.

This applicator 1 includes a pair of electrode bodies 2a, 2
The feeders 3a and 3b are connected to the feeders 3a and 3b, respectively, and a plurality of connectors 4 are provided between the feeders 3a and 3b. This electrode body 2
A and 2b are constructed by attaching a water bag 6 to an electrode plate 5, and feeders 3a and 3b are connected to the electrode plate 5. The water bag 6 is provided on the side of the heated part of the electrode plate 5, and has a cooling liquid and cooling water chambers for cooling the electrode plate 5, and a cooling liquid tube 7 and a cooling water tube 8 are connected to each other. There is.

The feeders 3a and 3b have one end connected to the electrode plate 5 and the other end removably connected to the treatment device body (not shown), and the tube 10 is secondarily coated on the wire body 9 which has been primarily coated. , constructed with double safety structure. This tube 10 is made of silicone sponge or the like.

The connecting body 4 holds the two feeders 3a and 3b in parallel, and is composed of a first connecting piece 11 and a second connecting piece 12, which can be attached and detached.
Both connecting pieces 11 and 12 are connected to elongated base pieces 13 and 1.
4, each made of consensus resin, 1 base piece
Fixing holes 13a and 14a are bored at one end of each of the fixing holes 3 and 14, respectively. The fixing holes 13a, 14a almost match the wire bodies 9 of the feeders 3a, 3b, and the tubes 10 of the feeders 3a, 3b are divided, and the tubes 10 clamp the base pieces 13, 14 through which the wire bodies 9 are passed. Then, the position is fixed.

Furthermore, five engaging protrusions 15 are arranged in parallel on the base piece 13 of the first connecting piece 11, and the protrusions 15 (engaging portions) are constructed by connecting a collar portion 15b to the tip of the body portion 15a. ing. On the other hand, five engagement holes 16 are bored in the base piece 14 of the second connection piece 12 in correspondence with the protrusions 15 . This engagement hole 16 (engaged part)
is composed of a hole 16a corresponding to the protrusion body 15a, and a protrusion 16b into which the protrusion flange 15b fits into the front periphery of the hole 16a. and,
By inserting and removing each projection 15 into each engagement hole 16, both connecting pieces 11 and 12 can be attached and detached.

Next, the mounting operation of each electrode body 2a, 2b will be explained.

Each of the electrode bodies 2a, 2b is connected to each feeder 3a,
The other end of 3b is connected to the main body of the treatment device, and is brought into close contact with the heated part of the living body. At this time, both feeders 3a,
3b is supported in parallel by a plurality of connecting bodies 4, each connecting body 4 inserts each protrusion 15 into an engagement hole 16, and both connecting pieces 11, 12 are connected together, and the feeder 3a, 3b is supported.

The electrode bodies 2a and 2b are configured to have the same shape, but there are various sizes depending on the shape of the heated portion. For example, as shown in FIG. 7, there are small electrode bodies 2c, which are combined in accordance with the parts to be heated. In that case, first, as shown in Figure 6,
Remove the protrusion 15 from the engagement hole 16, and remove both connecting pieces 1.
Separate 1 and 12. After that, the small electrode body 2c
the first or second connecting piece 11 or 12 attached to the
Install. As a result, different types of electrode bodies 2a, 2
c, and both feeders 3a and 3b are supported in parallel. At this time, both electrode bodies 2a and 2c are combined with their center positions being equal.

Further, the number of engaging protrusions 15 between each feeder 3a, 3b, and 3c is kept constant, and the length thereof is variable. In other words, when all five protrusions 15 are inserted into the engagement holes 16, the shortest length is reached, four, three
If you reduce it one by one, it will become longer. Treatment is performed by changing this interval depending on the area to be heated, and by changing the interval between the electrode bodies 2a, 2b, and 2c.

In this embodiment, the engaging part and the engaged part of the connecting body 4 are the protrusion 15 and the engaging hole 16, but hooks, hook-and-loop fasteners, etc. may also be used. Anything that can be made variable is fine.

Further, although the electrode bodies 2a, 2b, and 2c are provided with water bags 6, it is not necessary to provide them in this invention.

(F) Effects of the invention As described above, according to the applicator of the biotherapeutic device of this invention, since the two feeders are connected by a separable connecting body, one of the electrode bodies of the pair is
Since only one of the electrode bodies can be replaced, electrode bodies of different shapes can be combined depending on the area to be heated, so that treatment can be performed easily.

Furthermore, even if one of the electrode bodies fails, only the failed one can be replaced, so it can be repaired at low cost.

Furthermore, since the length between both feeders can be changed, the distance between both electrode bodies can be increased, so that the treatment range can be expanded.
