【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【発明の属する技術分野】本発明は、手術・処置・診断等に使用する外科手術用内視鏡及び外科手術用内視鏡と組み合わせて使用される外套管に関する。 The present invention relates to relates to the mantle tube that is used in conjunction with surgical endoscope and surgical endoscope used for surgery, treatment, diagnosis, or the like.

【0002】 [0002]

【従来の技術】従来から腹腔鏡下外科手術に代表される様に光学視管(以下、内視鏡)や鉗子等の処置具を体内に挿通し、内視鏡像を元に手術・処置・診断等が行われてきた。 BACKGROUND ART telescope as typified by laparoscopic surgery conventionally (hereinafter, endoscope) and a treatment instrument is inserted into the body, such as a forceps, surgical, treatment, the endoscopic image based on diagnosis and the like have been made. これらの作業は全て内視鏡像を元に行う為、内視鏡像が鮮明に維持できることが特に重要である。 These operations are for performing based on all the endoscopic image, it is particularly important that an endoscope image can be maintained clearly.

【0003】しかしながら、体内に挿通したとき、内視鏡先端のカバーガラスが体内の湿気により曇ってしまい、観察を妨げることがあった。 However, when inserted into the body, the cover glass of the endoscope tip fogged by moisture in the body, was to interfere with the observation. このような現象は次のような原因によるものである。 Such a phenomenon is due to causes such as the following. つまり、体内、例えば、 In other words, the body, for example,
腹腔内の温度は体温と略等しく、かつ湿度はかなり高い状態にある一方、手術室に準備されている内視鏡の温度は略室温になっている。 Temperature in the abdominal cavity substantially equal to the body temperature, and while humidity in the fairly high state, the temperature of the endoscope that has been prepared operating room are substantially room temperature. この両者の温度差により腹腔内の湿気が内視鏡先端のカバーガラス表面で結露し、曇ってしまう。 The temperature difference between the two moisture intraperitoneal condensation with a cover glass surface of the endoscope tip, the resulting cloudy.

【0004】このような曇りを防止するため、これまでは、使用する前に、例えば別に用意したお湯にあらかじめ内視鏡を浸して暖めておいたり、内視鏡を暖める装置を用いてあらかじめ内視鏡を暖めておいたり、さらにはカバーガラスに曇り防止剤(油脂等)を塗布したりする等、曇りを極力防止しながら内視鏡を用いており、不便であった。 [0004] In order to prevent such fogging, the past, prior to use, for example, or allowed to warm soak advance endoscope hot water prepared separately, by using the device for heating an endoscope inner advance or-warmed to endoscope further has using an endoscope, etc., while preventing fogging as possible or coating agents fogging on the cover glass (oils and fats), which is inconvenient.

【0005】一方、実公昭62-12118号公報に示される様に対物レンズに発熱皮膜を形成し、発熱皮膜に外部から電力を供給することで、対物レンズを暖め、結露を防止する機構を組み込んだコピー装置が提案されている。 On the other hand, to form a heating coating on the objective lens as shown in Japanese Patent Utility Model 62-12118, the heat generation film by supplying electric power from the outside, warm the objective lens, incorporating a mechanism for preventing dew condensation copy devices have been proposed it. これは、外部からの電力の供給が必要であり、また、外部からの電力供給の制御ため、温度センサーを含む制御回路、過熱防止の為の制限回路等を含む制御装置が必要であり、システムが非常に複雑になってしまうという欠点があった。 This requires the supply of power from the outside and, for control of the power supply from the outside, the control circuit including a temperature sensor, it is necessary to control device including a limiting circuit or the like for preventing overheating the system there has been a drawback that becomes very complicated. このため、内視鏡装置には不向きなものである。 Therefore, those unsuitable for endoscopic device.

【0006】また、特許第2671745号公報に示される様に、照明光の一部を内視鏡先端部の加熱に用いる様にした形式の内視鏡も提案されているが、内視鏡先端部の温度を制御する手段が無いため、これを使用する場合には、内視鏡先端を体組織に近づけない等、使用上の配慮が必要なものであった。 Further, as shown in Patent No. 2,671,745 and JP-format endoscope the manner used to heat the endoscope tip portion part of the illumination light has also been proposed, the endoscope tip because there is no means for controlling the temperature of the parts, in the case of using this, like not close the endoscope distal end to body tissue, it was necessary consideration for use.

【0007】また、特開昭64-83241号公報に示される様に、内視鏡先端に温めた気体を当てるようにした加温手段も考えられているが、この方式では上記同様に制御装置が必要であり、制御装置が大掛かりになるという欠点、さらには面倒な操作やメンテナンスが必要になる等の欠点があった。 Further, as shown in JP-A-64-83241, it is thought also heating means so as to apply the gas warmed the endoscope tip, in this method similarly to the above control device is required, drawback control apparatus is large-scale, more cumbersome operation and maintenance has a disadvantage such that required.

【0008】 [0008]

【発明が解決しようとする課題】本発明は上記課題に着目してなされたものであり、その目的とするところは、 The object of the invention is to solve the present invention has been made in view of the above-mentioned problems, and has as its purpose,
特別に外部からの電力供給が不必要であり、また、制御装置が不用なものであり、さらには、面倒な操作やメンテナンスの必要もなく、先端に設けるカバーガラスの曇りを防止できる外科手術用内視鏡および外套管を提供することにある。 Specially a power supply from the outside is unnecessary, and the control device is intended for waste, furthermore, without the need for troublesome operations and maintenance, surgical capable of preventing fogging of a cover glass provided on the tip It is to provide an endoscope and the mantle tube.

【0009】 [0009]

【課題を解決するための手段および作用】請求項1に係る発明は、内視鏡の外表面又はその外表面近傍のうち体内に挿入される部分に温度差により発電する発電素子が配置され、当該内視鏡の光学部材の近傍には、上記発電素子が発電した電流をエネルギー源として発熱し、上記光学部材を加温する発熱素子を配置したことを特徴とする外科手術用内視鏡である。 Means and operation for solving the problems of the invention according to claim 1, the power generation element for generating a temperature difference disposed on the outer surface or portion to be inserted into the body of its outer surface near the endoscope, in the vicinity of the optical member of the endoscope, and heating the current which the power generating element has power as an energy source, in surgical endoscope for mirrors, characterized in that a heating element for heating the optical member is there.

【0010】請求項2に係る発明は、外科手術用内視鏡と組み合わせて使用される外套管において、体内に挿入される側の端部に光学部材が配され、当該外套管の外表面又はその外表面近傍のうち体内に挿入される部分に温度差により発電する発電素子が配置され、当該外套管の光学部材近傍には、上記発電素子が発電した電流をエネルギー源として発熱し、上記光学部材を加温する発熱素子を配置したものである。 [0010] The invention according to claim 2, in the mantle tube that is used in combination with a surgical endoscope, the optical member is arranged on an end portion of the side to be inserted into the body, the outer surface of the mantle tube or its power generating element which generates power by temperature difference portion inserted into the body of the outer surface near is disposed on the optical member vicinity of the mantle tube generates heat current the power generating device has power as an energy source, the optical it is obtained by placing the heating element for heating the member.

【0011】一般に内視鏡のカバーガラス等の光学部材の外表面には曇りが発生し易い。 [0011] Generally haze on the outer surface of the optical member such as a cover glass of the endoscope tends to occur. 内視鏡が挿入される体腔内の温度は略体温であり、水分も豊富にあるために湿度も高い。 Temperature inside the body cavity endoscope is inserted is substantially body temperature, humidity is high for water also are abundant. 一方、挿入前の内視鏡は通常室内に置いておかれるため、略室温となっており、そのような内視鏡を体内に挿入すると、相対的に冷たい内視鏡のカバーガラス等の光学部材の外表面で結露が発生し、画像に曇りが生じる。 Meanwhile, since the endoscope prior to insertion is placed at the normal room, substantially it has a room temperature, insertion of such an endoscope into a body, an optical cover glass of relatively cool endoscope condensation at the outer surface of the member occurs, cloudy images occurs. これは、内視鏡と組み合わせて使用される外套管の場合も同様である。 This is also the case of the mantle tube that is used in conjunction with an endoscope.

【0012】本発明では、体内に挿入される部分に温度差によって発電する発電素子、例えばペルチェ素子を設け、上記体温と、内視鏡又は外套管の温度差によって電力を発生させる。 In the present invention, the power generation element for generating the temperature difference in the portion to be inserted into the body, for example, a Peltier element is provided, and the body temperature, to generate electric power by a temperature difference between the endoscope or trocar. 発電素子に発生した電力でカバーガラス等の光学部材近傍に配置された発熱素子を発熱させ、 The disposed optical member near such cover glass with electric power generated in the power generating element heating element to generate heat,
光学部材の温度を上げることにより体腔との温度差を無くし、曇りの発生を押さえる。 Eliminating the temperature difference between the body cavity by raising the temperature of the optical member, suppress the occurrence of fogging.

【0013】また、内視鏡又は外套管は体腔内にあるため、時間と共に内視鏡又は外套管の温度は体腔の温度に近づいていく。 Further, an endoscope or trocar is due to the body cavity, the temperature of the endoscope or trocar with time approaches the temperature of the body cavity. それにつれ、発電素子11の発電量は低下していく。 As it, the power generation amount of the power generation element 11 decreases. しかし、内外の温度差が無くなれば、曇りも発生しない状況となるため、電力は必要が無くなる。 However, if the temperature difference between the inside and outside disappears, since the situation that does not occur cloudy, power does not need.
すなわち、自動的に出力を制限しているのと同等である。 That is, it is equivalent to limiting the output automatically. 従って、あらゆる外部からの電力の供給、温度等の検出手段・制御手段及び過熱防止等の装置が不用であり、簡単で安価な構造で曇り防止手段を構築できる。 Thus, supply of electric power from any external, is unnecessary detection means and control means and devices overheating prevention temperature etc., it can be constructed preventing means cloudy simple and inexpensive structure.
