Description

本発明は、柔軟性を有したシャフトの先端部に球状の膨出部が形成された医療用消息子の製造方法の技術分野に関するものである。 The present invention relates to the technical field of a method for manufacturing a medical Ryoyo Shomusuko the bulged portion of the spherical is formed on the tip portion of the shaft having a flexibility.

一般に、医療機器の一つとして、柔軟性を有したシャフトの先端部に球状の膨出部が形成された医療用消息子が知られている。このような医療用消息子は、金属製あるいは合成樹脂製のものであって、例えば、手術時に血管等の内腔に差込まれて、縫合部位の補助、血管内径の測定、吻合部分への血流の停止等を行うための血管縫合用内腔維持カテーテルとして用いられている（例えば、非特許文献１参照）。
ところで、前記非特許文献１に記載されている樹脂製の医療用消息子（血管縫合用内腔維持カテーテル）の構造を実際に分解して調べてみたところ、図３に示す如く、非特許文献１の医療用消息子１００は、シャフト１０１と膨出部１０２とが別部材で形成されているとともに、膨出部１０２に形成された嵌入孔１０２ａにシャフト１０１の先端部を嵌入して接着材１０３で接着することにより、シャフト１０１と膨出部１０２とが一体的に固定されていた。さらに、一体的に固定されたシャフト１０１および膨出部１０２はコーティング材１０４によって被覆されていたが、該コーティング材１０４は、シャフト１０１と膨出部１０２との接着部において接着材１０３の漏洩等による細かい凸凹等をカバーするために必要であると思われる。 In general, as one of the medical devices, there is known a medical extinguisher in which a spherical bulge is formed at the tip of a flexible shaft. Such medical devices are made of metal or synthetic resin, and are inserted into the lumen of a blood vessel or the like at the time of surgery, for example, assisting a suture site, measuring the inner diameter of a blood vessel, It is used as a lumen maintenance catheter for blood vessel suturing for stopping blood flow (see, for example, Non-Patent Document 1).
By the way, when actually disassembling and examining the structure of the resin-made medical extinguisher (lumen maintenance catheter for vascular suture) described in Non-Patent Document 1, as shown in FIG. In the first medical device 100, the shaft 101 and the bulging portion 102 are formed as separate members, and the distal end portion of the shaft 101 is fitted into the fitting hole 102a formed in the bulging portion 102. By bonding at 103, the shaft 101 and the bulging portion 102 were fixed integrally. Further, the integrally fixed shaft 101 and the bulging portion 102 are covered with the coating material 104. However, the coating material 104 leaks the adhesive material 103 at the bonding portion between the shaft 101 and the bulging portion 102. It seems necessary to cover fine irregularities due to

以下、本発明の実施の形態について、図面に基づいて説明する。図面において、１は医療用消息子であって、該医療用消息子１は、柔軟性を有したシャフト１ａの先端部に球状の膨出部１ｂが形成されており、例えば、手術時に血管等の内腔に差込まれて、縫合部位の補助、血管内径の測定、吻合部分への血流の停止等を行うための血管縫合用内腔維持カテーテルとして用いることができる。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a medical extinguishing unit, and the medical extinguishing unit 1 is formed with a spherical bulging portion 1b at a distal end portion of a flexible shaft 1a. Can be used as a lumen maintenance catheter for vascular suture for assisting a suture site, measuring a blood vessel inner diameter, stopping blood flow to an anastomosis portion, and the like.

前記医療用消息子１は、ポリテトラフルオロエチレン（ＰＴＦＥ）樹脂製の細長い棒材２を切削加工することによりシャフト１ａと膨出部１ｂとが一体形成されたものであって、該医療用消息子１の切削加工は、後述するように旋盤３を用いて行う。   The medical extinguisher 1 has a shaft 1a and a bulging portion 1b integrally formed by cutting an elongated bar 2 made of polytetrafluoroethylene (PTFE) resin. The child 1 is cut using a lathe 3 as described later.

前記旋盤３は、ワークである棒材２を把持するチャックが取付けられた主軸、および該主軸を回転させるモータを備えた主軸部４（チャック、主軸、モータは何れも図示せず）と、該主軸部４を主軸の軸方向（Ｚ軸方向）に移動させるための主軸移動装置５と、主軸部４のチャックに把持された棒材２の先端側をガイドするガイドブッシュ６と、該ガイドブッシュ６から送り出される棒材２を切削するバイト７と、該バイト７を主軸の軸方向と直交する方向（Ｘ軸およびＹ軸方向）に移動させるバイト移動装置８と、バイト７による切削中に棒材２の切削済み部分を支持して該部分の振れ止めを行うパイプ状の振れ止めガイド９と、該振れ止めガイド９を移動させる振れ止め部移動手段（図示せず）等を備えて構成されており、さらに、旋盤３の付属装置として、切削完成品である医療用消息子１を受ける完成品受箱１０を具備している。   The lathe 3 includes a main shaft provided with a chuck for gripping a bar 2 that is a workpiece, and a main shaft portion 4 (a chuck, main shaft, and motor are not shown) including a motor that rotates the main shaft, A main shaft moving device 5 for moving the main shaft portion 4 in the axial direction (Z-axis direction) of the main shaft, a guide bush 6 for guiding the tip end side of the bar 2 held by the chuck of the main shaft portion 4, and the guide bush A cutting tool 7 that cuts the bar 2 fed from 6, a cutting tool moving device 8 that moves the cutting tool 7 in a direction perpendicular to the axial direction of the main shaft (X-axis and Y-axis directions), and a bar that is being cut by the cutting tool 7. A pipe-shaped steady-state guide 9 that supports a cut portion of the material 2 and supports the steady portion, and a steady-state portion moving means (not shown) for moving the steady-state guide 9 is provided. And even lathe As the auxiliary device is provided with a finished product receiving box 10 for receiving the medical Shomusuko 1 is a cutting finished product.

そして、前記旋盤３を用いて医療用消息子１を製造する場合には、まず、主軸部４を、最もバイト７から遠い初期位置に位置させた状態で、ワークである棒材２の中間部を主軸部４のチェックで把持するとともに、該棒材２の先端側をガイドブッシュ６に支持せしめる。しかる後、主軸を回転させながら主軸移動装置５により主軸部４をバイト７側に移動させ、該主軸部４の移動に伴いガイドブッシュ６にガイドされながら送り出される棒材２をバイト７で切削して医療用消息子１を製造していく。この場合、まずシャフト１ａ部分を切削してから膨出部１ｂ部分を切削し、該膨出部１ｂ部分の切削終了後に切断することで、シャフト１ａと膨出部１ｂとが一体形成された医療用消息子１が製造されるが、切削中において切削済のシャフト１ａ部分は、主軸と同軸上に配されたパイプ状の振れ止めガイド９の筒内９ａに挿入されていくようになっており、これにより、切削済のシャフト１ａ部分が主軸の回転に伴って振れてしまうことを確実に防止できるようになっている。
尚、前記切削加工により製造される医療用消息子１の寸法は、例えば、長さ３０ｃｍ〜６０ｃｍ、シャフト１ａの径０．５ｍｍ〜１．５ｍｍ、膨出部１ｂの径０．８ｍｍ〜３．０ｍｍに設定されるが、これに限定されるものではないことは勿論である。 And when manufacturing the medical extinguisher 1 using the said lathe 3, first, the intermediate part of the bar 2 which is a workpiece | work in the state which located the main spindle part 4 in the initial position farthest from the cutting tool 7. Is gripped by checking the main shaft portion 4 and the tip side of the bar 2 is supported by the guide bush 6. After that, the main shaft portion 4 is moved to the bite 7 side by the main shaft moving device 5 while rotating the main shaft, and the bar 2 fed out while being guided by the guide bush 6 along with the movement of the main shaft portion 4 is cut with the bite 7. To manufacture medical consumer 1 In this case, first, the shaft 1a portion is cut, and then the bulging portion 1b portion is cut, and then cut after the cutting of the bulging portion 1b portion, whereby the shaft 1a and the bulging portion 1b are integrally formed. The cutting shaft 1 is manufactured, and the portion of the shaft 1a that has been cut during cutting is inserted into the in-cylinder 9a of the pipe-shaped steadying guide 9 that is arranged coaxially with the main shaft. As a result, it is possible to reliably prevent the cut shaft 1a portion from shaking with the rotation of the main shaft.
The dimensions of the medical blank 1 manufactured by the cutting process are, for example, 30 cm to 60 cm in length, 0.5 mm to 1.5 mm in diameter of the shaft 1a, and 0.8 mm to 3 mm in diameter of the bulging portion 1b. Although it is set to 0 mm, of course, it is not limited to this.

叙述の如く構成された実施の形態において、医療用消息子１は、柔軟性を有したシャフト１ａの先端部に球状の膨出部１ｂが形成されたものであるが、該医療用消息子１のシャフト１ａと膨出部１ｂとは、ポリテトラフルオロエチレン樹脂製の棒材２を旋盤３で切削加工することにより一体形成されている。   In the embodiment configured as described above, the medical extinguisher 1 has a spherical bulging portion 1b formed at the tip of a flexible shaft 1a. The shaft 1 a and the bulging portion 1 b are integrally formed by cutting a bar 2 made of polytetrafluoroethylene resin with a lathe 3.

而して、棒材２を旋盤３で切削加工するだけで、シャフト１ａと膨出部１ｂとが一体形成された医療用消息子１を製造できることになって、シャフト１ａが膨出部１ｂから抜け出てしまう惧れを確実に回避できるうえ、医療用消息子１の製造を大幅に簡単化することができ、しかも、シャフトと膨出部とが別部材の場合に必要である、シャフトと膨出部とを一体化するための接着材や、接着部をカバーするためのコーティング材が不要となって、コスト低減に大きく貢献できる。   Thus, by simply cutting the bar 2 with the lathe 3, the medical extinguisher 1 in which the shaft 1a and the bulging portion 1b are integrally formed can be manufactured, and the shaft 1a can be removed from the bulging portion 1b. The possibility of slipping out can be surely avoided, the manufacturing of the medical device 1 can be greatly simplified, and the shaft and the bulging portion are required when the shaft and the bulging portion are separate members. An adhesive for integrating the protruding portion and a coating material for covering the bonded portion are unnecessary, which can greatly contribute to cost reduction.

さらにこのものにおいて、棒材２はポリテトラフルオロエチレン樹脂製のものが用いられているが、ポリテトラフルオロエチレン樹脂は、旋盤３による切削加工が容易であるとともに、シャフト１ａに必要な柔軟性と、膨出部１ｂに必要な硬さとを有している。しかも、ポリテトラフルオロエチレン樹脂製の棒材２は、市販されている汎用的なものを用いることができ、入手が簡単であるという利点もある。   Further, in this material, the rod 2 made of polytetrafluoroethylene resin is used, but the polytetrafluoroethylene resin is easy to cut with a lathe 3 and has the flexibility required for the shaft 1a. It has the necessary hardness for the bulging portion 1b. Moreover, as the bar 2 made of polytetrafluoroethylene resin, a commercially available general-purpose material can be used, and there is an advantage that it is easily available.

また、医療用消息子１の製造に用いる旋盤３は、切削中に棒材２の切削済み部分を支持して該部分の振れ止めを行う振れ止めガイド９を備えており、該振れ止めガイド９によって、細長い医療用消息子１を切削する場合であっても、切削中に旋盤３の主軸の回転に伴い切削済み部分が振れて切削加工の妨げになるような不具合を確実に防止することができる。   Further, the lathe 3 used for manufacturing the medical extinguisher 1 includes a steady guide 9 that supports the cut portion of the bar 2 during the cutting operation to prevent the steady portion, and the steady guide 9 Thus, even when the elongated medical device 1 is cut, it is possible to surely prevent a problem that the cut portion may be shaken with the rotation of the main shaft of the lathe 3 during the cutting and hinder cutting. it can.

さらに、前記旋盤３による棒材２の切削は、シャフト１ａ部分の切削後に膨出部１ｂ部分の切削を行う一方、振れ止めガイド９は、切削中に切削済みのシャフト１ａ部分を支持して該部分の振れ止めを行う構成となっており、これにより、振れ止めガイドによる切削済み部分の振れ止めを確実に行うことができる。   Further, the cutting of the bar 2 by the lathe 3 cuts the bulged portion 1b after the shaft 1a is cut, while the steady rest guide 9 supports the already cut shaft 1a during cutting. The configuration is such that the portion is steady, and thus, the steady portion of the cut portion can be reliably prevented by the steady guide.

尚、本発明は上記実施の形態に限定されないことは勿論であって、棒材２は、切削加工が容易で、シャフトに必要な柔軟性と膨出部に必要な硬さとを有した材質のものが要求され、そこで、本実施の形態ではポリテトラフルオロエチレン樹脂製の棒材２を用いたが、これに限定されることなく、上記要求に適合する他の樹脂、例えば、ポリカーボネート樹脂製のものを用いることもできる。   Needless to say, the present invention is not limited to the above embodiment, and the bar 2 is made of a material that is easy to cut and has the flexibility necessary for the shaft and the hardness necessary for the bulging portion. Therefore, in this embodiment, the rod 2 made of polytetrafluoroethylene resin is used. However, the present invention is not limited to this, and other resins that meet the above requirements, for example, made of polycarbonate resin, are used. Things can also be used.

本発明は、柔軟性を有したシャフトの先端部に球状の膨出部が形成された医療用消息子を製造する場合に利用することができる。   INDUSTRIAL APPLICABILITY The present invention can be used when manufacturing a medical extinguisher in which a spherical bulge is formed at the tip of a flexible shaft.
