It is characterized by the fact that it has been subjected to a buildup (17, 17) .

さらに、本発明に係る係止ピン材の使用方法は、請求項4に記載されたアッセンブリにおける係止ピン材(11)を手術で摘出された臓器検体の観察固定用として使用することを特徴とし、請求項4に記載されたアッセンブリにおける係止ピン材(11)を屠体あるいは食肉用ブロックへの管理用タグの装着用として使用することを特徴としている。
Furthermore, the method of using the locking pin material according to the present invention is characterized in that the locking pin material (11) in the assembly according to claim 4 is used for observation and fixation of an organ specimen that has been removed by surgery. The locking pin material (11) in the assembly described in claim 4 is used for mounting a management tag on a carcass or meat block .

本発明に係る係止ピン材及びその成形方法と成形された係止ピン材の使用方法は上記のように構成されている。そのため、係止ピン材はアッセンブリ状態で製造され、装着具で対象に打ち込む際に連結部(ゲート)を従来よりも細径としてあり、靱性の大きい素材であっても、ワンタッチ作業でランナーバーから切離することができる。また、射出成形時に密閉された金型のキャビティ中の隅々まで素材を流入させることができる。ここで使用するポリエーテルエーテルケトン(以下、PEEKと記す)は延伸性もよく、靱性があり破断することがなく、特に重量平均分子量70000〜84000の場合、成形条件を広く設定することができ、成形性も優れ、耐放射性も有する。   The locking pin material according to the present invention, a method for forming the locking pin material, and a method for using the molded locking pin material are configured as described above. Therefore, the locking pin material is manufactured in an assembled state, and the connecting part (gate) has a smaller diameter than before when driving into the target with a mounting tool, so even a tough material can be removed from the runner bar with a one-touch operation. Can be separated. Moreover, a raw material can be made to flow into every corner in the cavity of the metal mold | die sealed at the time of injection molding. The polyetheretherketone used here (hereinafter referred to as PEEK) has good stretchability, is tough and does not break, and in particular when the weight average molecular weight is 70,000 to 84000, the molding conditions can be set widely. Excellent moldability and radiation resistance.

また、本発明に係る係止ピン材の成形方法は、射出成形時の圧力と時間を限定することによって、所望する物性、特性を保有するPEEK製の係止ピン材を得ることができる。即ち、従来既知の圧力では物性が脆くなってしまい、従来の射出速度では金型のキャビティ中の細部までPEEKが流れ込まない虞を有していることが解消できる。   Moreover, the molding method of the locking pin material which concerns on this invention can obtain the locking pin material made from PEEK which has the desired physical property and characteristic by limiting the pressure and time at the time of injection molding. That is, it is possible to solve the problem that the physical properties become brittle with a conventionally known pressure, and PEEK may not flow into the details of the mold cavity at the conventional injection speed.

さらに、本発明に係る成形方法によって成形された係止ピン材を断熱材や防音材の固定用として使用することで、密接度合が固定されていない部分と変化が小さくなり、熱リーク量を低減することができ、覆う機器への断熱効果を良好なものとすることができ、使用環境温度が−200℃から+200℃まで可能となる。   Furthermore, by using the locking pin material molded by the molding method according to the present invention for fixing a heat insulating material or a soundproofing material, the change from the portion where the closeness is not fixed is reduced, and the amount of heat leak is reduced. The heat insulation effect to the equipment to cover can be made favorable, and use environment temperature becomes possible from -200 degreeC to +200 degreeC.

また、本発明に係る係止ピン材を手術で摘出された臓器検体を対象として個体情報を記録したICチップを備えた管理用タグの装着用として使用すると、従来の煩わしい作業は一切不要となるうえ、係止ピン材の素材が血液や体液、保存用のホルマリンやその他の化学剤に対して耐性が強く変質することがなく、有効に管理保存することができる。   In addition, when the locking pin material according to the present invention is used for mounting a management tag including an IC chip in which individual information is recorded for an organ specimen extracted by surgery, the conventional troublesome work becomes unnecessary. Moreover, the material of the locking pin material does not strongly change the resistance to blood, body fluids, storage formalin and other chemical agents, and can be effectively managed and stored.

さらに、本発明に係る係止ピン材を屠体や食肉ブロック、生体標本を対象として個体情報を記録したICチップを備えたタグの装着用として使用すると、素材が血液や肉汁そして洗浄用の水に対しても耐性が強く変質することがなく、流通過程を管理するについて対象物を変質させることもなく有効なものとなり、傷口の閉塞用としてもワンタッチでの使用ができる。   Further, when the locking pin material according to the present invention is used for mounting a tag including an IC chip in which individual information is recorded for a carcass, a meat block, or a biological specimen, the material is blood, gravy, and water for washing. As a result, it is effective for managing the distribution process without altering the object, and can be used with one touch for closing a wound.

図面として示し、実施例で説明したように構成したことで実現した。   This was realized by configuring as illustrated in the drawings and described in the examples.

次に、図1、図2を参照して、特に断熱材固定用として使用することを目的とした係止ピン材について説明する。図中1は本発明に係る係止ピン材2、2‥を本実施例では1.5mmの等ピッチで並設したアッセンブリを示している。このアッセンブリ1はPEEK、それも重量平均分子量72800〜81000のものを素材として射出成形されており、そのPEEKの溶融粘度挙動においてシェアレイト(せん断速度)が300〜400にあって溶融粘度が200Mpa以下とされている。この溶融粘度を有することで、加熱シリンダからスプルーを通して密閉された金型のキャビティ内の隅々まで流入することができる。   Next, with reference to FIG. 1 and FIG. 2, a description will be given of a locking pin material intended to be used particularly for fixing a heat insulating material. In the figure, reference numeral 1 denotes an assembly in which locking pin members 2, 2... According to the present invention are arranged side by side at an equal pitch of 1.5 mm in this embodiment. This assembly 1 is injection-molded using PEEK, which has a weight average molecular weight of 72800 to 81000, and the PEEK has a shear viscosity of 300 to 400 and a melt viscosity of 200 Mpa or less. It is said that. By having this melt viscosity, it is possible to flow from the heating cylinder through the sprue to every corner of the sealed mold cavity.

前記射出成形は射出の充填ピーク圧力を150Mpa以下、特に80〜150Mpaでなされる。これは従来の射出圧力180〜280Mpaの高圧力によると、物性が脆くなってしまうためでこれを是正している。また、射出速度は従来の50〜180mm/secより速い200〜280mm/secによりなされる。これは従来の射出速度では金型のキャビティの細部までPEEKが流れないことを是正している。   The injection molding is performed at an injection filling peak pressure of 150 Mpa or less, particularly 80 to 150 Mpa. This is because the physical properties become brittle when the conventional injection pressure of 180 to 280 Mpa is used, which is corrected. The injection speed is 200 to 280 mm / sec, which is faster than the conventional 50 to 180 mm / sec. This corrects that PEEK does not flow to the details of the mold cavity at the conventional injection speed.

また、前記したアッセンブリ1は装着具に装填して、順次係止ピン材2、2‥を一本づつ送り、切断して装着するための直線状のランナーバー3を有している。この実施例では、このランナーバー3の幅は1mm、高さは1.4mmを想定している。   Further, the assembly 1 described above has a linear runner bar 3 that is loaded into a mounting tool, sequentially feeds the locking pin members 2 one by one, cuts and mounts. In this embodiment, it is assumed that the runner bar 3 has a width of 1 mm and a height of 1.4 mm.

このランナーバー3には係止ピン材2、2‥を一体的に連結する連結部(ゲート)4、4‥が備えられている。この連結部4、4‥はランナーバー3側を幅広く、係止ピン材2、2‥側をやや幅狭く構成してあるが、この係止ピン材2、2‥側に沿った部分の径を、従来は1.0mm以上あったものを0.3〜0.8mm、好ましくは0.6mmの細径としてある。   The runner bar 3 is provided with connecting portions (gates) 4, 4. The connecting portions 4, 4... Are wide on the runner bar 3 side and the locking pin materials 2, 2... Are slightly narrower, but the diameter of the portion along the locking pin materials 2, 2. In the prior art, the diameter of 1.0 mm or more is 0.3 to 0.8 mm, preferably 0.6 mm.

係止ピン材2は直線状としたファイバー部5を有しており、このファイバー部5の一端(打ち込み作業時の基端)に、対象物の打ち込み手前側を抑止する抑止用横桿6を一体に備えており、この抑止用横桿6は実施例にあって長さ6.0mm、幅0.8mm、高さ0.3mmのフラットなやや平板状として、その抑止作用として対象物である断熱材の表面に喰い込むことを少なくしている。   The locking pin member 2 has a straight fiber portion 5, and a restraining reed 6 for suppressing the front side of the object to be driven is provided at one end of the fiber portion 5 (a base end during driving operation). This restraining reed 6 is a flat, slightly flat plate having a length of 6.0 mm, a width of 0.8 mm, and a height of 0.3 mm in the embodiment, and is an object as its deterring action. Less bite into the surface of the insulation.

また、前記したファイバー部5の他端(打ち込み作業時の先端)には丸横桿の係止部7が一体に備えられており、この係止部7の略中央外面が前記連結部(ゲート)4によってランナーバー3と連結されており、この係止部7の外面に沿って装着具のカッターにより連結部(ゲート)4が切断され、係止ピン材2は単体となり、この係止部7がスリット付の中空ニードル内をピストンで押され、対象物を通過し、復元して対象物の向こう側を抑止する。この際、ファイバー部5は中空ニードルのスリットから排出される。こうして係止部7は対象物の向こう側を抑止し、前記抑止用横桿6とともに抜け止めを図っている。尚、この係止部7は長さ6.0mm、径は0.6mmを本実施例では設定している。 Further, the other end (tip at the time of driving operation) of the fiber part 5 is integrally provided with a round horizontal hook engaging part 7, and the substantially central outer surface of the engaging part 7 is connected to the connecting part (gate). ) 4 is connected to the runner bar 3, and the connecting portion (gate) 4 is cut along the outer surface of the locking portion 7 by the cutter of the mounting tool, and the locking pin material 2 becomes a single unit. 7 is pushed by the piston in the hollow needle with the slit, passes through the object, restores and inhibits the other side of the object. At this time, the fiber part 5 is discharged from the slit of the hollow needle. In this way, the locking portion 7 prevents the object from going beyond, and prevents it from coming off together with the restraining reed ridge 6. In this embodiment, the locking portion 7 has a length of 6.0 mm and a diameter of 0.6 mm.

さらに、ファイバー部5は本実施例にあっては延伸加工によって長さを15mm(延伸前は8.0mm)、径は延伸加工によって0.3〜0.4mm(延伸前は0.5mm)となっている。   Further, in this embodiment, the fiber part 5 has a length of 15 mm (8.0 mm before stretching) by stretching and a diameter of 0.3 to 0.4 mm (0.5 mm before stretching) by stretching. It has become.

ここに示した係止ピン材2、2‥によって断熱材を固定すると、縫着状態とは異なって、密着状態をなくさせ、固定部分も非固定部分と同様の関係となるので固定部分における熱リーク(漏れ)が低減され、断熱作用をより良好なものとできる。   When the heat insulating material is fixed by the locking pin materials 2, 2,... Shown here, the contact state is eliminated unlike the sewing state, and the fixed portion has the same relationship as the non-fixed portion. Leakage (leakage) is reduced, and the heat insulation effect can be made better.

続いて、図3乃至図5を参照して、特に手術で摘出した臓器検体の観察固定や、屠体あるいは食肉ブロックに管理用のタグを装着するのに使用する係止ピン材について説明する。図中10は実施例1と同様にPEEKによって製造された係止ピン材11、11‥のアッセンブリであり、PEEKの溶融粘度や製造時の射出の圧力、速度は実施例1と同様である。   Next, with reference to FIG. 3 to FIG. 5, a description will be given of the locking pin material used for observing and fixing organ specimens excised especially by surgery, and attaching a management tag to a carcass or meat block. In the figure, reference numeral 10 denotes an assembly of locking pin members 11, 11... Manufactured by PEEK as in the first embodiment. The melt viscosity of PEEK and the injection pressure and speed at the time of manufacturing are the same as those in the first embodiment.

このアッセンブリ10も直線状のランナーバー12を有しており、連結部(ゲート)13、13‥を介して係止ピン材11、11‥が一体に連結されている。この例にあってランナーバー12は幅2mm、高さが4mmの直方体とされている。連結部(ゲート)13は二段構成とされ、ランナーバー12と直接連結される部分である第一段部13aは径0.6mmの円柱状とされ、この第一段部13aと係止ピン材11の係止部14となる横棒部分を連結する第二段部13bは幅0.4mm、高さ0.6mmの断面楕円状に形成し、カッターによる切断作用をより容易なものとしてある。尚、係止部14は径0.6mmとされている。   This assembly 10 also has a linear runner bar 12, and the locking pin members 11, 11... Are integrally connected via connecting portions (gates) 13, 13. In this example, the runner bar 12 is a rectangular parallelepiped having a width of 2 mm and a height of 4 mm. The connecting portion (gate) 13 has a two-stage configuration, and the first step portion 13a, which is a portion directly connected to the runner bar 12, has a cylindrical shape with a diameter of 0.6 mm. The first step portion 13a and the locking pin The second step portion 13b that connects the horizontal bar portions to be the locking portions 14 of the material 11 is formed in a cross-sectional ellipse shape having a width of 0.4 mm and a height of 0.6 mm so that the cutting action by the cutter is easier. . Note that the locking portion 14 has a diameter of 0.6 mm.

係止ピン材11はファイバー部15を有しており、このファイバー部15も途中で径を異ならしめた二段構成とされており、前記した係止部14側は径0.46mmの細径の第一段部15aとし、後述するパドル部16とこの第一段部15aとを連結する第二段部15bは径0.6mmの太径のものとし、補強を図っている。また、第一段部15aの基端と係止部14の連結部分と、第二段部15bとパドル部16との連結部分には各々補強用の肉盛り17、17‥が施されている。   The locking pin material 11 has a fiber portion 15, and the fiber portion 15 has a two-stage configuration with different diameters on the way, and the locking portion 14 side has a small diameter of 0.46 mm. The first step portion 15a and a second step portion 15b connecting the paddle portion 16 and the first step portion 15a, which will be described later, have a large diameter of 0.6 mm for reinforcement. Further, reinforcing bases 17, 17... Are applied to the connecting portion between the base end of the first step portion 15a and the locking portion 14 and the connecting portion between the second step portion 15b and the paddle portion 16, respectively. .

前記したパドル部16は側面から見て楕円状とした平板とされており、その中心部分に、端部に向けて徐々に径が大きくなるコア部18が設けられている。このパドル部16は、対象物に取り付けられる管理用タグの抜け止めとして作用する。   The paddle portion 16 described above is a flat plate having an elliptical shape when viewed from the side, and a core portion 18 whose diameter gradually increases toward the end portion is provided at the central portion thereof. The paddle portion 16 acts as a retaining tag for the management tag attached to the object.

この場合の係止ピン材11もアッセンブリ10のランナーバー12を装着具に装填し、係止ピン材11を一本づつ送りながら、連結部(ゲート)13、特に細径の第二段階13bをカッターで切断し、係止部14をピストンでスリット付きの中空ニードルへ送ることで対象物に装着されるが、タグを取り付けるには、ニードルの先端をタグの吊持用透孔に宛てがってトリガーを操作する。このことで、タグを吊った状態で係止ピン材11は対象物に装着される。係止部14は対象物を貫通するのではなく、対象物の内部に止まり保有する弾性で復元され、係止される。   In this case, the locking pin member 11 is also loaded with the runner bar 12 of the assembly 10 in the mounting tool, and while feeding the locking pin member 11 one by one, the connecting portion (gate) 13, particularly the second stage 13 b with a small diameter, is provided. It is attached to the object by cutting with a cutter and sending the locking portion 14 to a hollow needle with a slit with a piston. To attach the tag, the tip of the needle is directed to the through hole for holding the tag. To operate the trigger. Thus, the locking pin member 11 is attached to the object with the tag suspended. The locking portion 14 does not penetrate through the object, but is restored and locked by the elasticity retained and retained inside the object.
