イクロサージヤリー用器具に関する。 That is, in the present invention, a sliding member slidably inserted into a guide member and a cylindrical member are fixed together, and a holder is provided at the rear of the guide member to slidably hold a sphere therein. The member is screwed, and a handle body is screwed to the rear part of the holding member, and the base of the tip member inserted into the cylindrical member is fixed to the holding core, and the rear end of the sliding member is The sphere to be brought into contact is configured to be able to be pressed by a lever, and as the lever is pressed, the sliding member slides forward against the coil spring, and the gripping portion formed at the tip of the tip member and the tip of the cylindrical member The present invention relates to a microsurgery instrument characterized in that it is configured to be closed.
以下、図面に示す実施例を基に本考案を具体的
に説明する。
Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.
先端部材3は筒状部材4に挿通され、該筒状部
材4の後方部は摺動部材6に固着されている。先
端部材3の基部は保持コア11に嵌挿されピン8
を介してガイド部材7に間接的に止着され、保持
コア11は摺動部材6の長孔61内に配置されて
いる。 The tip member 3 is inserted through a cylindrical member 4, and the rear portion of the cylindrical member 4 is fixed to a sliding member 6. The base of the tip member 3 is fitted into the holding core 11 and the pin 8 is inserted into the holding core 11.
The holding core 11 is indirectly fixed to the guide member 7 via the holding core 11 and is disposed within the elongated hole 61 of the sliding member 6 .
また、ガイド部材7の後方部は保持部材9の前
方部に螺着されており、該保持部材9の後方部は
把手本体1の前方部に螺着されている。 Further, the rear part of the guide member 7 is screwed to the front part of the holding member 9, and the rear part of the holding member 9 is screwed to the front part of the handle body 1.
ガイド部材7と摺動部材6間に配置されたコイ
ルバネ10は摺動部材6を常に矢印e方向へ付勢
している。従つて、後述する操作によつて摺動部
材6の摺動に伴い筒状部材4が矢印b方向へ移動
すると、先端部材3と筒状部材4の先端に形成さ
れた挾持部5が閉ざされてゆき術中に於いて縫合
糸や組織を挾持することができる。 A coil spring 10 disposed between the guide member 7 and the sliding member 6 always urges the sliding member 6 in the direction of arrow e. Therefore, when the cylindrical member 4 moves in the direction of the arrow b as the sliding member 6 slides by the operation described later, the clamping portion 5 formed at the tip of the tip member 3 and the cylindrical member 4 is closed. It can hold sutures and tissues during surgery.
摺動部材6の後端部には球体12が当接され、
該球体12は保持部材9内に摺動自在に保持され
ている。レバー2は押圧部21で四方向より球体
12を押圧できるように配置されている。 A sphere 12 is brought into contact with the rear end of the sliding member 6,
The sphere 12 is slidably held within the holding member 9. The lever 2 is arranged so that the pressing portion 21 can press the sphere 12 from four directions.

レバー2の押圧部21は第3図で明示せるように
部分的に曲線状に形成されており、これは押圧時
の初動操作力を緩和する役目をなし、球体12を
初動時からスムーズに摺動させることができる。 The rear parts of the plurality of levers 2 for pressing and sliding the spheres 12 are fitted into the handle body 1, and the rear ends of the integrally connected levers are attached to the rear end of the handle body 1. Pin 1 is screwed onto fixing member 13.
It is fixed at 4. The pressing part 21 of the lever 2 for pressing the sphere 12 is partially curved as shown in FIG. can slide smoothly from the initial operation.
単独または同時に押圧することのできるレバー
2を矢印a方向へ押圧すると、レバー2の押圧部
21は球体12を押圧し、球体12は矢印b方向
へ摺動し、摺動部材6はコイルバネ10に抗して
b方向へ摺動する。 When the lever 2, which can be pressed individually or simultaneously, is pressed in the direction of arrow a, the pressing part 21 of the lever 2 presses the sphere 12, the sphere 12 slides in the direction of arrow b, and the sliding member 6 is pressed against the coil spring 10. It slides in the b direction against the resistance.

Since the present invention has the configuration as explained above,
It is possible to prepare various holding parts with different structures and to make them detachable together with the guide member 7, and moreover, when the guide member 7 is removed, the sphere 12 is held in the holding member 9 without falling off. Therefore, it is easy to attach and detach, and tweezers and scissors with a structure suitable for the purpose can be used.
