ている。9. When implanting the platinum electrode body for a pacemaker into the heart, it is necessary to make sure that it is implanted securely and to prevent hair loss after implantation, and to make the surface area as large as possible and the contact area of the tab. In addition, it is necessary to avoid causing unnecessary damage to the inside of the human body, and for this reason, in order to manufacture microscopic platinum electrode bodies, it is necessary to avoid extreme irregularities, brushes, etc. Creative efforts have been made to prevent this from occurring. For example, as shown in Fig. 1, the head 2 of the rivet-shaped platinum electrode body 10 is formed into a spherical shape by pressing with a header machine or cutting by lace processing to avoid unnecessary damage to the inside of the body. death,
In addition, a large number of minute through holes 3 or blind holes are bored in the spherical head 2 so as to be securely held on the heart wall.
A flesh wall is inserted into the minute through hole 3 or blind hole to hold it, and a cavity 4 is provided inside to reduce the weight.
本発明は、斯かるペースメーカー用白金電極体に求めら
れる性能ケさらによシ確実に高いものにし、その上重量
をさらに軽減し且つ強度を向上させたものである。The present invention ensures that the performance required of such a platinum electrode body for a pacemaker is even higher, and further reduces the weight and improves the strength.
以下本発明によるペースメーカー用白金電極体の一実施
例を第２図によって説明すると、リベツ設され、内部に
空洞４が設けられた上、頭部２′全体の組織が海綿状に
形成されている。An embodiment of the platinum electrode body for a pacemaker according to the present invention will be described below with reference to FIG. 2. In addition to being riveted and having a cavity 4 inside, the entire structure of the head 2' is formed in a spongy shape. .
このように本発明のペースメーカー用白金電極体は、そ
の頭部２′が海綿状体よシ成るので、その表面はぼそほ
そした極めて小さな凹凸面である。As described above, since the head 2' of the platinum electrode body for a pacemaker of the present invention is made of a spongy body, the surface thereof has extremely small irregularities.
従って、心臓部に埋め込む際、その表面の凹凸により人
体内部に傷を付けることがない。また頭部２′のスルホ
ール３又は盲穴の内壁にも極めて小さな凹凸があるので
心臓部に埋め込んだ際、肉壁がスルホール３又は盲穴に
入り込んで係止されて抜は止めされ、白金電極体１′は
確実に保持される。さらに頭部２１の表面積は極めて大
きく、従って心臓部に埋め込んだ際、肉壁との接触面積
が大きいので、通電時の電気効率め二著しく向上する。Therefore, when implanted into the heart, the unevenness of the surface will not cause any damage to the inside of the human body. In addition, the inner wall of the through hole 3 or blind hole in the head 2' has extremely small irregularities, so when it is embedded in the heart, the flesh wall enters the through hole 3 or the blind hole and is locked, preventing removal of the platinum electrode. Body 1' is held securely. Furthermore, the surface area of the head 21 is extremely large, so when it is implanted in the heart, the contact area with the flesh wall is large, so the electrical efficiency during energization is significantly improved.
また頭部２／の組織はポーラス状となっているので、重
量が極めて軽い。従って心臓機能に負担をかけることが
なく、シか有白金の使用量が少くなシ、コストが低減す
る。Furthermore, since the structure of the head 2/ is porous, it is extremely light in weight. Therefore, there is no burden on heart function, the amount of platinum used is small, and costs are reduced.
以上詳記した通シ本発明のペースメーカー用白金電極体
は、頭部が海綿状体であるので、心臓部に埋め込んだ際
、より確実に心臓壁部に保持することができて取れるこ

さらに重量が極めて軽いので心臓機能に負担がかからず
マストも低く、従来の白金電極体にとって代わることの
できる画期的なものと！える。As described in detail above, the platinum electrode body for a pacemaker of the present invention has a spongy head, so when it is implanted in the heart, it can be more securely held on the heart wall and will not come off. , and has high electrical efficiency and excellent performance when energized.
Furthermore, it is extremely light in weight, so it does not put a strain on cardiac function, and the mast is low, making it an innovative product that can replace conventional platinum electrode bodies! I can do it.
