【発明が解決しようとする課題】ところで、使用後の内視鏡(特に、内視鏡の挿入部)には患者の血液・胃液・ [SUMMARY OF THE INVENTION Incidentally, the endoscope after use (particularly, the insertion portion of the endoscope) to the blood, gastric fluids, the patient's
便等の汚物や細菌が付着しており、これを洗浄消毒することなく放置したまま次の検査で使用すると感染を引き起こす。 Filth and bacteria have adhered, such as feces, causing the infection to be used in the next inspection is left unattended without washing and disinfecting it. そのため、内視鏡は使用されるごとにその表面および内部管路が洗浄消毒されており、これによって、 Therefore, the surface and internal conduit whenever the endoscope used are cleaned and disinfected, thereby,
汚染された内視鏡からの感染が防止されている。 Infection is prevented from contaminated endoscope. 特に、 In particular,
近年では、院内感染の問題があり、感染を引き起こす心配のある病気をもった患者に内視鏡を使用した後はその内視鏡を入念に洗浄消毒するようにしている。 In recent years, there is a nosocomial infection problem, after using an endoscope to a patient having a disease of concern causing the infection is to be carefully cleaned and disinfected the endoscope.

【0004】しかしながら、こうした洗浄消毒作業はかなりの時間を要するため、次から次へと手術を行なえないという不都合がある。 [0004] However, since it takes such a cleaning and disinfecting work for quite some time, there is a disadvantage that can not be performed the surgery from the next to the next. また、このような洗浄消毒は手間がかかるため作業上負担となる。 Furthermore, such washing and disinfecting will be working on burden because it takes time and effort.

【0005】そのため、最近では、作業上の負担を軽減する上からも、また、衛生上の面からも、そして、手術効率の面からも、こうした内視鏡の少なくとも汚染度の高い挿入部を使い捨てにしたいという要求がある。 [0005] Therefore, recently, from the top to reduce the load on the work, also in terms of hygiene, and, in terms of surgical efficiency, the high insertion portion of the at least degree of contamination of such endoscopes there is a demand for disposable. そのためには、使い捨て可能な安価な挿入部の提供が必要となる。 For this purpose, it is necessary to provide a disposable inexpensive inserts.

【0006】しかし、生体内等に挿入される内視鏡の挿入部は、その内部に多数のリレーレンズおよびライトガイド等を内蔵しており、その外筒および内蔵部材は非常に精密な形状を要求されることから、高価な物となっている。 However, the insertion portion of the endoscope is inserted into vivo or the like, it incorporates a plurality of relay lenses and light guides or the like therein, the outer tube and internal member a very precise shape from required that has become an expensive ones. 特に、撮像素子を内蔵した電子内視鏡にあっては非常に高価となる。 In particular, in the electronic endoscope with a built-in image sensor becomes very expensive. したがって、安価な内視鏡の挿入部を提供することは非常に難しいものがある。 Therefore, to provide an insertion portion of an inexpensive endoscope is very difficult.

【0007】本発明は上記事情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、安価で使い捨てが可能な挿入部を備えた内視鏡を提供することにある。 [0007] The present invention has been made in view of the above circumstances, and its object is to provide an endoscope with a disposable can be inserted portion at low cost.

【0008】 [0008]

【課題を解決するための手段及び作用】上記課題を解決するために、本発明は、被写体を照明するための照明光学系と、撮像素子と、この撮像素子に被写体像を結像する観察光学系とを樹脂で一体化して挿入部形状に仕上げた挿入部をを内視鏡に設けたものである。 To solve SUMMARY and operation for solving the above problems, the present invention includes an illumination optical system for illuminating an object, an imaging element, an observation optical that forms a subject image on the imaging device the system is an insertion portion finished insertion portion shape by integrating a resin which was disposed in the endoscope.

【0009】このように、被写体を照明するための照明光学系と被写体像を結像する観察光学系とを樹脂で一体化することによって挿入部を構成したことから挿入部を安価に製造できるため、挿入部を使い捨てにすることが可能となる。 [0009] Thus, it is possible to inexpensively manufacture the insertion portion from that constitute the insertion portion by integrating the observation optical system for imaging illumination optical system and an object image for illuminating the object with a resin , it becomes possible to make the insertion portion disposable.

【発明の効果】以上説明したように、本発明の内視鏡は、被写体を照明するための照明光学系と被写体像を結像する観察光学系とを樹脂で一体化することによって挿入部を構成したことから挿入部を安価に製造できる(したがって、安価に購入できる。)ため、挿入部を使い捨てにすることが可能となる。 As described in the foregoing, the endoscope of the present invention, the insertion portion by integrating the observation optical system for imaging illumination optical system and an object image for illuminating the object with a resin the insertion portion from the structure was less expensive to manufacture (and therefore, can be purchased inexpensively.) Therefore, it becomes possible to make the insertion portion disposable.

【0029】したがって、使用後に挿入部を洗浄消毒する作業を行なわなくて済むため、手術効率の向上を図ることができるとともに、併せて、院内感染の防止も図ることができる。 [0029] Thus, since it is not necessary to perform the task of cleaning and disinfecting the insertion portion after use, it is possible to improve the operation efficiency, together, it can also be achieved prevention of nosocomial infections.
