【発明の詳細な説明】 鍋中電極組立体を挿入する装置及び方法本発明は、移植蟻牛刺激装f (coc hlear implant)のための挿入工具、並びに鍋中電極リードを患者 の耳に挿入するために該工具を使用する方法に関する。[Detailed description of the invention] Apparatus and method for inserting an electrode assembly in a pan The present invention relates to an implanted ant cow stimulator Insertion tool for hlear implant) and electrode lead in the pot method of using the tool for insertion into the ear of a person.
移植暢牛刺激装置の刺激を行う電極組立体は、暢牛仕切りの内側、−fflに鼓 室階内に置かれる。通常の電極リードを持った主な問題は、購牛根の線維、並び に電極リードのti及びリード・ワイヤを回復不能に損傷することなく、電極リ ードを鱗牛内に挿入するということにある。従来技術においては、電極リードは 、ワニロ鉗子もしくはY形状の鉤爪のいずれかでもって、鍋中窓を通して視線( the 1ine of sight)に沿ってかつ暢牛の基底ターン(bas al turn)に沿って外科的に挿入されなければならない、ワニロ鉗子は電 極を挿入する力及び挿入方向を適切に制御するが、電極に対する損傷の危険性が 高い。The electrode assembly for stimulating the implanted cow stimulator is located inside the cow partition, at -ffl. placed inside the room. The main problem with regular electrode leads is that the fibers in the root canal, lined up electrode lead without irreversibly damaging the electrode lead ti and lead wire. The idea is to insert the cord into the scale. In conventional technology, the electrode lead , with either alligator forceps or Y-shaped claws, look through the window in the pot ( along the 1ine of sight and along the basal turn of the nogyu The alligator forceps must be surgically inserted along the alturn. Properly control the force and direction of electrode insertion, but without risk of damage to the electrode. expensive.
ワニロ鉗子はまた、鍋牛内で電極の配列を正しく配向するよう定期的に移動され て置き換えられなければならない、というのは、該ワニロ鉗子は、制限された回 転角度を通してのみ電極リードをつかむことができるからである。Y形状の鉤爪 は!極に対する損傷を最小にするが、視線に沿って最適な方向に挿入力を与える ように用いることができない、!極す−ドをつかむことができないので、鉤爪は 、電極を回転させて鯖牛内に正しく置くように用いることができない。The Wanilo forceps are also moved periodically to properly orient the electrode array within the pot. The alligator forceps must be replaced with a limited number of rotations. This is because the electrode lead can only be grasped through the rotation angle. Y-shaped claw teeth! Minimizes damage to poles but provides insertion force in optimal direction along line of sight Can't be used like that! I can't grab the pole, so the claws are , the electrode cannot be rotated and used to place it correctly within the mackerel.
本発明の目的は、電極組立体を保護すると共に、蛯牛内への電極リードの成功裏 の手技を許容する、電極リードを挿入するための挿入工具及び技術を提供するこ とである。It is an object of the present invention to protect the electrode assembly and to ensure a successful introduction of the electrode lead into the calf. To provide an insertion tool and technique for inserting an electrode lead that allows the procedure of That is.
本発明の原理に従って、電極リードには、シリコン・ゴムから成るのが好ましい カラーが設けられる。カラーは電極組立体上の所定の点で電極リードの後部に付 着される。カラーは、カラーの内部直径が電極リードの外部直径よりもわずかに 大きいようにフレオンもしくはその他の適切なガスで膨張される。このことは、 製造中にリードを通してカラーを滑り込ませるのを可能とする。カラーの配W後 、フレオンは発散され、カラーはくリードの外部直径と等価な)その元の寸法に 戻る。この収縮の結果は摩擦すべりばめとなる。にかわ(好ましくはシラスティ ックA)がカラーの前方縁に塗布される。カラーは、挿入の完了後に鍋中窓の外 側に配置されるように位置付けられる。In accordance with the principles of the invention, the electrode leads are preferably comprised of silicone rubber. A color is provided. The collar is attached to the back of the electrode lead at a predetermined point on the electrode assembly. It will be worn. The collar has an internal diameter slightly larger than the external diameter of the electrode lead. Expanded with Freon or other suitable gas to make it larger. This means that Allows the collar to be slipped through the lead during manufacturing. After color arrangement W , the freon is diverged to its original dimensions (equivalent to the external diameter of the collar foil). return. The result of this contraction is a friction slip fit. Glue (preferably Shirasti) A) is applied to the front edge of the collar. The collar is placed outside the window inside the pot after completion of insertion. Positioned to be placed on the side.
挿入もしくはつかみ工具は、カラー及びリード間で適合するよう設計された親指 のつめのような形状の仕上げ端を先端で有している0本発明の主な長所は、(カ ラーを通して)電極リードにつかみ工具を圧搾もしくは摩擦ばめするようにして いるので、ワニロ鉗子を用いた場合に生じ得るような、電極配列に対する起こり うる損傷を禁止するということである。この取付モードはまた、軸線に沿って直 接、最適に挿入力を与えるのを許容する。The insertion or grasping tool is a thumb tool designed to fit between the collar and lead. The main advantage of the present invention is that it has a claw-shaped finished end at the tip. through the electrode lead) by squeezing or friction-fitting the gripping tool onto the electrode lead. Therefore, there are no problems with the electrode arrangement, such as those that may occur when using Wanilo forceps. This means that any damage caused by water is prohibited. This mounting mode also supports direct alignment along the axis. contact, allowing optimal insertion force to be applied.
さらに、外科医は、つかみ工具がリードを滑って電極組立体もしくは患者の耳の 繊細な組織を損傷するという恐れ無しで、電極リードを回転させるよう該つかみ 工具を用いることができる。このことは、視線に沿って力を与えるようにもしく は電極リードをつかんで回転させるように用いることができない従来技術のY形 状の鉤爪とは対照をなす、従来技術のワニロ鉗子は電極挿入の力及び方向を充′ 分に制御するけれどし、$極す−ドを蛸牛内に完全に挿入するために、それは、 リードから定期的に移動もしくは取り除かれてリード上のさらに後方の点に置き 換えられなければならない。本発明では、外科医はつかみ工具を全く移動させる こと無く、軸線に沿って前方への一定の力を与えることができる。In addition, the surgeon may be concerned that the grasping tool may slip down the lead and cause the electrode assembly or the patient's ear to be damaged. The grip allows the electrode lead to be rotated without fear of damaging delicate tissue. Tools can be used. This also seems to give force along the line of sight. is a Y-type conventional technology that cannot be used to grip and rotate the electrode lead. In contrast to the shaped claws, prior art alligator forceps control the force and direction of electrode insertion. However, in order to fully insert the pole into the octopus, it is Periodically moved or removed from the lead and placed at a point further back on the lead. must be replaced. With the present invention, the surgeon moves the grasping tool at all. It is possible to apply a constant forward force along the axis without any force.
本発明は、また、対称電極及び非対称電極の双方に用いることができる。非対称 電極の場合、つかみ工具は、作用もしくは活性電極の真上にある(例えば180 度離れる)ようにカラーの下に置かれる。マークがつかみ工具のハンドルの前部 に置かれ、これにより、外科医が電極リードな甥牛内に挿入して電極組立体がも はや見えないとき、作用電極の配向を決定することができ、暢牛内に作用電極組 立体を正しく置くように電極リードを回転させることができる。対称電極の場合 、電極゛配列に対する工具の配置は重要ではない。電極配列の挿入が完了した後 、つかみ工具はリードの軸線に沿って滑らせることにより取り除かれ、リードは 、カラー上にY形状の鉤爪を一時的に配置することにより(工具の除去が、リー ドを除去しないように)安定に保持され得る。The invention can also be used with both symmetrical and asymmetrical electrodes. asymmetrical In the case of electrodes, the gripping tool is directly above the working or active electrode (e.g. 180 It is placed under the collar so that it is separated (degrees apart). The mark is on the front of the handle of the gripping tool. This allows the surgeon to insert the electrode lead into the calf and remove the electrode assembly. When it is no longer visible, you can determine the orientation of the working electrode and place the working electrode assembly inside the The electrode leads can be rotated to properly position the solid. For symmetrical electrodes The placement of the tool relative to the electrode array is not critical. After electrode array insertion is complete , the gripping tool is removed by sliding it along the axis of the reed, and the reed is , by temporarily placing a Y-shaped claw on the collar (tool removal is can be held stably (without removing the code).
