尿管結石回収装置の背景技術として、バルーン拡張装置を備えた特許文献7実開平02−6012内視鏡用異物回収具がありカテーテルの外側を拡張する装置となっている、本発明はカテーテルの内側を拡開する装置であり、カテーテルを拡開することにより結石を挟み込み回収を容易にする、特許文献1から特許文献8の案件との大きな違いである、独国特許出願公開第1566147号明細書とはバルーンとシリンジの使用が似ているようですが、上記の記載にもあるように、本発明バルーンにてカテーテルの内側を拡開する装置ある、独国特許出願公開第1566147号明細書はカテーテルの外側を拡張する装置となっている、本発明のシリンジ(9)は結石を吸い寄せる装置であり、独国特許出願公開第1566147号明細書と As background art of ureteral stones recovery device, balloon dilatation device including a Patent Document 7 real Hei 02-6012 endoscope foreign object collection device is located has a device to extend outside of the catheter, the present invention provides a catheter a device for expanding the inner to facilitate pinching recovered stones by expanding the catheter is a major difference between projects in Patent Document 8 from EP 1, DE 1566147 patent specification While writing and seems use of a balloon and the syringe are similar, as also in the above description, a device for spreading the inside of the catheter in the present invention the balloon, DE 1566147 Pat has a device to extend outside of the catheter, the syringe of the present invention (9) is a device Suiyoseru stones, and German Patent application Publication No. 1566147 大きな違いである。 It is a big difference. 特許文献9の案件のなかにカテーテルの内側を拡張する装置と結石を吸い寄せる装置一体型の案件が見当たらない。 I do not see device and calculi the Suiyoseru device integrated projects to extend the inner catheter Some projects Patent Document 9.

この改善策として、尿管結石鋏み込み回収装置を使用する事により結石を粉砕せずカテーテルにてソフトに挟み込み尿管や尿道に傷を付けずに回収することが出来る。 As a remedy, it can be recovered with no damage to the ureter and urethra sandwiched soft in the catheter without crushing the stones by using a recovery device narrowing scissors stone ureter.

解決しようとする問題点は、結石が尿管にある間痛み止めの注射や座薬などの薬を使用し血尿と激痛に耐えなければならない、解決するためには、尿管結石を簡単な装置で取り除き早期に治療が出来激痛から開放されることと高額医療費の軽減にあった。 A problem to be solved is, stones must withstand hematuria and pain using a medicine such as injection or suppository between pain in the ureter, to solve is, a ureteral stone in a simple device there was to be released from the severe pain can early in treatment to remove and to the reduction of high medical expenses.

本発明は、結石を挟み込み回収を容易にするため、カテーテルの拡張装置のバルーン及びシリンジ(6)と、結石を吸い寄せるクダ及びシリンジ(9)の装置の一体型のクダを、尿管に挿入し、先端部のクダをシリンジ(9)で結石を吸い寄せる装置を作動させ後にバルーンに加圧し結石を受け入れを容易なるように拡張することにより、カテーテルも同時に拡開し結石がカテーテルの受け入れの状態を確認後、一体型のクダをカテーテル内に結石を吸い寄せた状態で、引き込みバルーンを減圧し結石を挟み込み回収を容易にする発明である。 The present invention, in order to facilitate pinching recovered stones, a balloon and the syringe (6) of the expansion device of the catheter, the Kedah integrated devices Suiyoseru stones Kedah and Syringe (9), the urinary tract inserting, by extending the pressurized stones balloon so facilitate acceptance after actuating the device Suiyoseru stones the Kedah the tip syringe (9), acceptance of the catheter is also expanded at the same time stones catheter after confirming the state, the Kedah integrated in a state in which sucked the stones in the catheter, an invention to facilitate recovery sandwiched by the lead-balloon vacuum stones.

本発明の挟み込み回収装置を使用する事により、カテーテルに結石が保護され、尿管や尿道に傷を付けないように取り出され、激痛から解放され1〜2時間後に普通の健康体に回復、また診療時間も大幅に短縮され又高額医療費の削減につながる。 By using the pinch recovery device of the present invention, stones are protected catheter is withdrawn so as not to damage the ureter and urethra, recovery normal healthy 1-2 hours after being released from severe pain, also clinic time also leads to a significantly shortened also reduction of high medical costs.
