Abstract
(57)【要約】
【課題】従来は硝子体カッターは真っ直ぐであった。し

【解決手段】硝子体カッターの吸引孔に近い部分を湾曲
または屈曲させることで、便利で安全にしようとした。
(57) [Summary] [Problem] Conventionally, a vitreous cutter has been straight. Therefore, it was inconvenient and dangerous. An object of the present invention is to make a portion close to a suction hole of a vitreous cutter bend or bend so as to be convenient and safe.
Description
この考案は硝子体カッターの先端に近い部分を湾曲させたも のである。 The idea is to curve the portion near the tip of the vitreous cutter.
眼科手術工学機械 Ophthalmic surgery engineering machine
眼科の手術の中でも、難易度の高い手術の一つに、硝子体手 術がある。疾患の種類によっても若干異なるが、硝子手術の主 目的は硝子体を除去することである。硝子体はゲル状の物質な ので、手術でそれを除去する際に、そのまま吸引して除去する ことが不可能で、吸引孔にギロチン式の刃をつけた、直線状の 硝子体カッターとよばれる装置を用いで、細かく切りながら吸 引している。 One of the most difficult operations in ophthalmic surgery is vitreous surgery. Depending on the type of disease, the primary purpose of vitreous surgery is to remove the vitreous. Since the vitreous body is a gel-like substance, it cannot be removed by suction when it is removed by surgery.It is a straight vitreous cutter with a guillotine-type blade in the suction hole. Suction is performed by using a device that can be cut into small pieces.
しかし従来のこの硝子体カッターは直線状であったため、器 具の眼内への挿入部など、部位によっては硝子体の除去が困難 であった。また、吸引孔が網膜に近づくことが多く、網膜を誤 って切除する合併症が生じることも少なくなかった。 However, since the conventional vitreous cutter has a straight shape, it is difficult to remove the vitreous body in some parts such as a portion where the device is inserted into the eye. In addition, the suction hole often approached the retina, and complications of erroneously resecting the retina often occurred.
本考案は、その欠点を除くためになされたもので、硝子体カ ッターの先端の吸引孔に近い部分を、図面の様に彎曲させたも のである。これは疾患などにあわせ、様々な角度に湾曲させる 。 The present invention has been made in order to eliminate the drawback, in which a portion near the suction hole at the tip of the vitreous cutter is curved as shown in the drawing. This bends at various angles according to the disease.
本考案はこのような構造であるから、硝子体の切除可能な範 囲が広がり、吸引孔と網膜との距離が離れるため、網膜を切除 する危険も減らすことができる。 Since the present invention has such a structure, the range in which the vitreous body can be cut is widened, and the distance between the suction hole and the retina is increased, so that the risk of cutting the retina can be reduced.
