[Problems to be solved by the invention]

従来、胸腔鏡手術及び腹腔鏡手術は、筒の部分が直線状の内視鏡と手術鉗子を挿入するため、少なくとも２カ所以上の皮膚切開を加える必要があり、一カ所の皮膚切開では内視鏡と手術鉗子が干渉して手術ができないという問題点があった。 Conventionally, in thoracoscopic surgery and laparoscopic surgery, it is necessary to make at least two skin incisions because an endoscope with a straight tube and surgical forceps are inserted, and it is necessary to make at least one skin incision. There was a problem that surgery could not be performed due to interference between the mirror and surgical forceps.

[Means for Solving the Problems]

上記目的を達成するために、内視鏡の筒の部分を湾曲させ、手術鉗子と内視鏡が干渉しないようにした。また、内視鏡の筒の部分を可塑性のある素材でつくることにより患者の体型にあわせて筒の部分の湾曲の程度を変えることができると同時に筒の部分の支持性を保つことができるようにした。 In order to achieve the above object, the tube portion of the endoscope is curved so that the surgical forceps and the endoscope do not interfere with each other. Also, by making the tube part of the endoscope from a plastic material, it is possible to change the degree of curvature of the tube part according to the body shape of the patient and at the same time maintain the supportability of the tube part.

[Effect of the invention]

内視鏡の筒の部分を湾曲させることで、一カ所の皮膚切開から手術鉗子と内視鏡を挿入した場合でも手術鉗子と内視鏡が干渉せず手術が可能となり、患者に加える皮膚切開の数を減らすことができる。また、内視鏡の筒の部分を可塑性のある素材でつくることにより患者の体型にあわせて筒の部分の湾曲の程度を変えることができ、湾曲の異なった内視鏡を複数準備する必要はなくなる。 By bending the tube part of the endoscope, even if the surgical forceps and the endoscope are inserted through a single skin incision, surgery can be performed without the surgical forceps and the endoscope interfering with each other. The number of incisions can be reduced. In addition, by making the tube part of the endoscope with a plastic material, the degree of bending of the tube part can be changed according to the patient's body shape, and it is necessary to prepare multiple endoscopes with different curves.
