。Conventionally, the outer shell is surrounded by a metal body, and the core part of the sheath heater has a current-carrying heat-generating resistance wire (hereinafter simply referred to as the heat-generating wire) embedded in insulating powder.The outer diameter of the sheath heater is usually 4 mm or more. The heat generation temperature is several hundred degrees Celsius.

紋針をヒーターによって伝熱より針金体を加熱させて、
紋針が所望の位置に設置されることによって目的を達す
るという方法を採らざるを得ながった。With conventional devices such as these, the area to be locally heated is very narrow, for example, within a gap of 1 mm, or when penetrated into the body cavity of a human or animal body to locally heat (in case of two uses, etc.) In conventional methods, a thin needle is attached to the tip of the pattern needle, and the wire body is heated by heat transfer using a heater.
They had no choice but to adopt the method of achieving their purpose by placing the crest needle in the desired position.
従来のこのような方法では、針金体が加熱されるがため
に針自体が全体的に加熱さ匙、かつ伝熱によるため加熱
まで時間がが＼る等の欠点がある。This conventional method has drawbacks such as the fact that the wire body is heated, so the needle itself is heated as a whole, and it takes a long time to heat up due to heat transfer.
之に反して本発明のものは、加熱を要する部分が極微小
部分であっても可能であり、従来のように発熱体からの
伝熱によるものでない等の他、後記の如き諸特徴をも併
せ有するものである。On the other hand, the present invention can heat even if the part that requires heating is extremely small, does not depend on heat transfer from a heating element as in the past, and has other features as described below. It has both.

４に接続されている。The present invention will be described in detail. FIG. 1 is a shape diagram of an embodiment of the present invention, and FIG. 2 is a cross-sectional diagram thereof. 1 is a heat generating needle. Reference numeral 11 denotes an outer shell metal body made of a corrosion-resistant alloy material such as stainless steel. 12 is an insulating powder such as magnesia, 13 is a heating wire buried in the insulating powder 12, and the terminal 1 is connected at the rear end.
Connected to 4.
１の発熱線の形状に於て、先端部分２は細径部分であり
６は大径部分からなりたっている。In the shape of the heating wire 1, the tip portion 2 is a small diameter portion, and the tip portion 6 is a large diameter portion.
普通の場合の実施例では２の外径は１ミリ以下であり、
３の外径も４ミリ以下のものが使用さ肚ている。先端部

。本発明の特徴に１の発熱針の内部構造である。第２図
に於て説明すれば１３の埋設されている発熱線の外径が
１の封体部の外径の大きさに比例して変化している点で
ある。In a normal case, the outer diameter of 2 is less than 1 mm,
3 with an outer diameter of 4 mm or less is being used. Further, the most distal end portion 21 of the distal end portion 2 constitutes a sharp cutting edge. One of the features of the present invention is the internal structure of the heating needle. Referring to FIG. 2, the outer diameter of the embedded heating wire 13 changes in proportion to the outer diameter of the enclosure 1.
即ち本発明の実施例では細径部２の部分に内設されてい

外径である。このことは本発明の発熱針の特徴ある作用
効果を意味するものである。即ち１４のターミナル部分
から通電された発熱線は４２より４１の方が細いので、
発熱温度も４１の方が高い、即ち本発明の発熱針は封体
部に於いて細径部分の方が発熱も早くかつ高いという温
度分布を有しているものである。That is, in the embodiment of the present invention, the outer diameter 41 provided inside the small diameter portion 2 is smaller than that of 42 provided inside the large diameter portion 3. This means that the heating needle of the present invention has a characteristic effect. In other words, the heating wire energized from the terminal part 14 is thinner in 41 than in 42, so
The heat generation temperature is also higher in 41, that is, the heat generation needle of the present invention has a temperature distribution in which heat generation is faster and higher in the narrower diameter portion of the envelope.

以下の細径部分を製作することが出来るものである。As a method for producing a heat generating needle having the characteristic performance of the present invention, for example, a heat generating wire serving as a core is placed in a pipe with a diameter of 6 mm or more, and an insulating powder such as magnesia is placed around it. After the body has been filled and configured, each pipe is gradually processed using dies, swaging, etc. to reduce its diameter, and then only the tip part is subjected to the above processing to produce a small diameter section of 1 mm or less. It is something that can be done.

する場合がある。４６が本実施例の位置である。As described above, in the case of the present invention, the heat generation temperature becomes brown quickly from the outer diameter part of 1 mm or less, so by taking advantage of this point and manufacturing it by adjusting the length of the small diameter part 2, it is possible to Target (2 heating can be carried out quickly. Also, the terminal part of the heating wire (= the heat temperature that the heating needle receives by continuing the terminal to a device that measures the electromotive force from the heating wire without applying electricity) In this case, the heat sensitive part of the heating wire may constitute the part to be alloy welded. 46 is the position in this example.
