本発明によると、円筒状の本体部の底面から内視鏡を延出させるとともに処置具を側面から延出させることとしているため、内視鏡による観察画面が処置具によって隠れてしまって、視野が狭くなり病変部およびその周辺が見えにくくなることが少なくなる。さらに、複数の処置具を患者体内へ導入する場合には内視鏡の観察視野の周囲側から処置具を病変部に到達させることが可能となるため、処置具同士または処置具と内視鏡とが干渉することが少なくなり、処置具及び内視鏡を病変部まで確実に到達させることができる。また、本体部内に処置具及び内視鏡を収容した状態で患者体内へ導入することができるので、複数の処置具を切開部分に同時に導入する場合であっても、切開の長さを大きくとらずに済む。  According to the present invention, since the endoscope is extended from the bottom surface of the cylindrical main body and the treatment tool is extended from the side surface, the observation screen by the endoscope is hidden by the treatment tool, and the visual field Becomes narrower and it is less likely that the lesion and its surroundings are difficult to see. Further, when a plurality of treatment tools are introduced into a patient body, the treatment tools can reach the lesion from the peripheral side of the observation field of the endoscope. And the treatment tool and the endoscope can surely reach the lesion. In addition, since the treatment tool and the endoscope can be introduced into the patient while being accommodated in the main body, even when a plurality of treatment tools are simultaneously introduced into the incision portion, the length of the incision is greatly increased. You do n’t have to.

以下、本発明に係る実施形態を図1〜8を参照しつつ詳しく説明する。本実施形態に係る対象物内部処置装置200、対象物内部処置システム300(図8)は、対象物としての患者の体内の病変部(対象部位)の治療を行うためのものであって、中央孔部20及び周辺孔部30を備える本体部10を有し、対象物内部処置システム300はさらに本体部操作手段60、内視鏡操作手段70、及び、処置具操作手段81、82を有する。  Hereinafter, embodiments according to the present invention will be described in detail with reference to FIGS. The objectinternal treatment device 200 and the object internal treatment system 300 (FIG. 8) according to the present embodiment are for treating a lesion (target part) in a patient's body as an object, The objectinternal treatment system 300 includes a main body operation means 60, an endoscope operation means 70, and treatment instrument operation means 81 and 82.

本体部10は、患者(対象物)の体内に導入される可撓性を有する円筒状部材で形成することができる。この本体部10は、図3に示すように、先端に行くほど外径が小さくなる円形断面を備える先端部11と、先端部11の後端面11aに固定された湾曲自在な湾曲部12とを備えている。本体部10は先端部11の先端から患者体内に導入され、病変部の位置に応じて体内の深部まで導入することができる。本体部10は、その後端部において接続された本体部操作手段60(図8)により、本体部10の患者体内への導入および導出のほか、湾曲部12の湾曲具合の調整を行うことができる。本体部操作手段60としては、例えば術者による手動操作、自動送出、巻取装置があり、これにより、本体部10は本体部操作手段60により外部から操作可能となる。  Themain body 10 can be formed of a flexible cylindrical member that is introduced into the body of a patient (object). As shown in FIG. 3, themain body 10 includes adistal end portion 11 having a circular cross section whose outer diameter decreases toward the distal end, and abendable bending portion 12 fixed to therear end surface 11 a of thedistal end portion 11. I have. Themain body 10 is introduced into the patient from the distal end of thedistal end 11, and can be introduced deep into the body depending on the position of the lesion. Themain body part 10 can adjust the bending state of thebending part 12 in addition to the introduction and derivation of themain body part 10 into the patient body by the main body operation means 60 (FIG. 8) connected at the rear end part. . Examples of the main body operation means 60 include manual operation by an operator, automatic transmission, and a winding device. Themain body section 10 can be operated from the outside by the main body operation means 60.

円筒状の本体部10は、その二つの底面のうち病変部110側に配置される底面(先端面)11bの中央から他方の底面(後端面)(不図示)へ向けて本体部10内を貫通する中央孔部20と、湾曲部12の側面12bから本体部10の後端面10c(図8)へ向けて本体部10内を貫通する周辺孔部30とを有している。中央孔部20には病変部(対象部位)を観察する内視鏡21が挿通され、内視鏡21は出口20bから病変部110側へ延出される。周辺孔部30は、中央孔部20の中心20aに関して等角度間隔(この例では180度間隔)に配置された二つの円形の孔部31、32から構成される。孔部31、32の出口側端部31b、32bの軸線は中央孔部20に対して傾斜しており、孔部31、32には病変部を処置する処置具41、42がそれぞれ挿通され、処置具41、42は出口31a、32aから外部へ延出される。出口31aと先端面11bとの距離は出口32aと先端面11bとの距離に等しくされている。出口31a及び出口32aの内径が同一であると、処置の内容、手順に応じて処置具41、42を入れ替えることができるため好ましい。また、処置具41、42を所望の角度にするために、出口31a、32aの内径を処置具41、42の外径より大きくすることが望ましい。The cylindricalmain body 10 is formed in themain body 10 from the center of the bottom surface (front end surface) 11b arranged on thelesioned part 110 side to the other bottom surface (rear end surface) (not shown) of the two bottom surfaces. Acentral hole portion 20 that penetrates and aperipheral hole portion 30 that penetrates through the inside of themain body portion 10 from theside surface 12b of thebending portion 12 toward therear end surface 10c (FIG. 8) of themain body portion 10 are provided. Anendoscope 21 for observing a lesioned part (target site) is inserted into thecentral hole 20, and theendoscope 21 extends from theoutlet 20b to thelesioned part 110 side. Theperipheral hole 30 is composed of twocircular holes 31 and 32 arranged at equal angular intervals (180 degrees in this example) with respect to thecenter 20a of thecentral hole 20.The axial lines of the outletside end portions 31b and 32b of thehole portions 31 and 32are inclined with respect to thecentral hole portion 20, and thetreatment tools 41 and 42 for treating the lesioned portion are inserted intothehole portions 31 and 32, respectively. Thetreatment tools 41 and 42 are extended to the outside from theoutlets 31a and 32a.

It is preferable that the inner diameters of theoutlet 31a and theoutlet 32a are the same because thetreatment tools 41 and 42 can be replaced according to the content and procedure of the treatment. In order to make thetreatment tools 41 and 42 have a desired angle, it is desirable that the inner diameters of theoutlets 31a and 32a be larger than the outer diameters of thetreatment tools 41 and 42.

孔部31及び孔部32を備えた本体部10の形成は既存の手法により行うことができる。例えば、孔部31及び孔部32と同一形状の円筒状部分を備えた型に熱溶融性の樹脂を流し込んで冷却固化することによって、孔部31及び孔部32を備えた本体部10を形成することができる。このように孔部31及び孔部32を形成することによって、本体部10内で内視鏡及び二つの処置具が絡んでしまって、または干渉し合って操作が困難となるおそれがなくなる。以上のように形成される本体部10は、例えば、本体部10の外径が5cmであるとき、孔部31、32、それぞれの内径を1.2cmとすることができる。また、先端部11及び中央孔部20は断面が円形でなくてもよい。  Formation of themain body part 10 provided with thehole part 31 and thehole part 32 can be performed by the existing method. For example, themain body 10 having thehole 31 and thehole 32 is formed by pouring a heat-meltable resin into a mold having a cylindrical portion having the same shape as thehole 31 and thehole 32 and solidifying by cooling. can do. By forming thehole portion 31 and thehole portion 32 in this way, there is no possibility that the endoscope and the two treatment tools are entangled or interfere with each other in themain body portion 10 and the operation becomes difficult. For example, when the outer diameter of themain body 10 is 5 cm, themain body 10 formed as described above can have the inner diameters of theholes 31 and 32 and 1.2 cm, respectively. Further, thedistal end portion 11 and thecentral hole portion 20 may not have a circular cross section.

It is desirable to enlarge it.

つづいて、図1〜3に示す対象物内部処置装置200、対象物内部処置システム300を用いた病変部の外科的治療の手順について説明する。
まず、患者体内の病変部を治療するために適切な箇所を切開する。複数の処置具を必要とする治療であっても対象物内部処置装置200を用いる場合は対象物内部処置装置200を患者体内に導入するのに必要な分だけ(例えば、本体部10の外径が5cmであれば約5cm)切開をすれば済むため患者に係る負担が少なくて済む。
Next, a procedure for surgical treatment of a lesion using the objectinternal treatment device 200 and the objectinternal treatment system 300 shown in FIGS.
First, an incision is made at an appropriate location for treating a lesion in a patient. Even when a treatment that requires a plurality of treatment tools is used, when the objectinternal treatment device 200 is used, only the amount necessary to introduce the objectinternal treatment device 200 into the patient (for example, the outer diameter of the main body 10). (If it is 5 cm, about 5 cm), it is only necessary to make an incision, so the burden on the patient can be reduced.

次に、図8に示すようにあらかじめ本体部操作手段60、内視鏡操作手段70、処置具操作手段81、82、画像表示手段87、91が本体部10、立体視内視鏡21、処置具41、42に接続された状態の対象物内部処置装置200を、切開部から患者体内100へ導入する。導入の際には、処置具操作手段81、82を操作することによって、処置具41、42は出口31a、32aから延出させずに本体部10内に収容された状態とすることが好ましい。導入中に処置具41、42が本体部10から延出して患者体内100を傷つけることを防止するためである。そして、立体視内視鏡21の視野範囲22が、図4に示すような病変部110およびその周辺、ならびに、処置具41、42それぞれの先端部分が観察可能となる位置で導入を止めて治療を開始する。  Next, as shown in FIG. 8, the main body unit operating means 60, the endoscope operating means 70, the treatment instrument operating means 81 and 82, and the image display means 87 and 91 are previously provided in themain body unit 10, thestereoscopic endoscope 21, and the treatment. The objectinternal treatment device 200 connected to thetools 41 and 42 is introduced into thepatient body 100 through the incision. At the time of introduction, it is preferable that thetreatment instruments 41 and 42 are accommodated in themain body 10 without extending from theoutlets 31a and 32a by operating the treatment instrument operating means 81 and 82. This is to prevent thetreatment tools 41 and 42 from extending from themain body 10 and damaging thepatient body 100 during the introduction. Then, the field-of-view range 22 of thestereoscopic endoscope 21 is treated by stopping the introduction at a position where thelesioned part 110 and its periphery as shown in FIG. 4 and the distal end portions of thetreatment tools 41 and 42 can be observed. To start.

対象物内部処置装置200は、立体視内視鏡21を囲むようにして処置具41、42を配置してあり、治療中は立体視内視鏡21の視野範囲の周囲側から処置具41、42が現れることとなる。このため、術者は病変部110、処置具41、42を認識しやすくなり、これにより操作が行いやすくなる。また、立体視内視鏡21を先端面11bから、処置具41及び処置具42を側面12bから延出させる構成としているため、立体視内視鏡21、処置具41及び処置具42が互いに干渉することが少なくなる。よって、病変部110が患者体内の深部にあっても、対象物内部処置装置200を患者体内の深部へ導入することができ、施術を安全かつスムーズに行うことができる。  In the objectinternal treatment device 200,treatment tools 41 and 42 are arranged so as to surround thestereoscopic endoscope 21, and thetreatment tools 41 and 42 are disposed from the periphery side of the visual field range of thestereoscopic endoscope 21 during treatment. Will appear. For this reason, it becomes easy for the surgeon to recognize thelesioned part 110 and thetreatment tools 41 and 42, thereby making the operation easier. Further, since thestereoscopic endoscope 21 is configured to extend from thedistal end surface 11b and thetreatment tool 41 and thetreatment tool 42 from theside surface 12b, thestereoscopic endoscope 21, thetreatment tool 41, and thetreatment tool 42 interfere with each other. Less to do. Therefore, even if thelesioned part 110 is in a deep part in the patient body, the objectinternal treatment device 200 can be introduced into the deep part in the patient body, and the treatment can be performed safely and smoothly.

以下に変形例について説明する。
本体部41a、42aに代えて、内視鏡の挿入部を用いることもできる。図9は、図7に示す例の処置具41〜45に代えて内視鏡の挿入部141a、142a、143a、144a、145aを5つの孔部にそれぞれ挿通した例である。この例では、把持鉗子41b、鋏鉗子42b、吸引チューブ43b、高周波止血鉗子44b、切開用高周波メス45bが、挿入部141a、142a、143a、144a、145aに設けられた鉗子チャンネル141h、142h、143h、144h、145hに挿通されている。挿入部141a、142a、143a、144a、145aには、処置具41、42、43、44、45と同様に、観察光学系、照明光学系、送気送水系、湾曲部が設けられている。このように構成すると、既存の内視鏡を利用できるため製造コストを削減することができる。
A modification will be described below.
Instead of themain body portions 41a and 42a, an insertion portion of an endoscope can be used. FIG. 9 is an example in which theinsertion portions 141a, 142a, 143a, 144a, and 145a of the endoscope are inserted into the five holes in place of thetreatment tools 41 to 45 in the example shown in FIG. In this example, graspingforceps 41b, scissors forceps 42b,suction tube 43b, high-frequency hemostatic forceps 44b, and incision high-frequency knife 45b are provided inforceps channels 141h, 142h, and 143h provided ininsertion portions 141a, 142a, 143a, 144a, and 145a. 144h and 145h. As with thetreatment instruments 41, 42, 43, 44, 45, theinsertion portions 141a, 142a, 143a, 144a, 145a are provided with an observation optical system, an illumination optical system, an air / water supply system, and a bending portion. If comprised in this way, since an existing endoscope can be utilized, manufacturing cost can be reduced.

図7に示す構成における本体部10、立体視内視鏡21、並びに処置具41〜45を一括してまたは選択的に操作することができる操作手段160を設けてもよい(図10)。さらに、立体視内視鏡21の観察光学系21b、21c、並びに処置具41〜45の観察光学系41c、42c、43c、44c、45cからの画像を一括して、または、選択的に表示可能な画像表示装置190を設けてもよい。このように構成することによって、省スペース化可能でコンパクトなシステムとなり、より少ない人数の術者によって効率的に治療を行うことができる。  An operation means 160 that can collectively or selectively operate themain body 10, thestereoscopic endoscope 21, and thetreatment tools 41 to 45 in the configuration shown in FIG. 7 may be provided (FIG. 10). Furthermore, images from the observationoptical systems 21b and 21c of thestereoscopic endoscope 21 and the observationoptical systems 41c, 42c, 43c, 44c and 45c of thetreatment tools 41 to 45 can be displayed collectively or selectively. A simpleimage display device 190 may be provided. With this configuration, a space-saving and compact system can be obtained, and treatment can be performed efficiently by a smaller number of surgeons.
