又はヘパリン等の抗血栓剤を含浸させたガーゼを介して
挟持したり、あるいは直接手で掴んでガイドワイヤを押
し・引き・回転等の操作をしていた。To insert a catheter into the body, a wire such as a guide wire is first inserted, and then the catheter is inserted into the body using the wire as a guide. After inserting this catheter to the target site, the guide wire is removed and a procedure such as contrast imaging or treatment is performed. During such a procedure, a wire such as a guide wire must be rotated, pushed, or pulled at hand during the process of inserting it into the body. Therefore, the operator must either hold the wire directly with a metal chuck or through gauze impregnated with an antithrombotic agent such as heparin, or hold the wire directly with his/her hand and push, pull, rotate, etc. was doing.

したり又は引いたりする操作を行なうのは困難である。However, when a wire such as a guide wire is held between metal chucks, there arises a problem that the polyurethane resin, hydrophilic coat, antithrombotic coat, etc. coated on the guide wire surface may peel off. On the other hand, a guide wire coated with a hydrophilic coating or the like is slippery, and it is difficult to rotate, push, or pull the guide wire when grasping it by hand and inserting it into the body.
このような不都合を解消すべく、本出願人はすでに、ガ

ラッシング操作ができる機構が要望されている。However, there is a demand for faster and more sophisticated catheter insertion operations, and in the operating device proposed above, the catheter and wire operating device are separate, so both hands are always occupied during the procedure. Simple one-handed operation is not possible. In addition, sometimes a thrombus may form inside the catheter, and a mechanism that can perform a flushing operation to prevent this is desired.
本発明はこのような実情に鑑み創案されたものであり、
その目的は、カテーテルと線材操作器具とを必要に応じ

Even when a wire is passed through the slit and inserted into the slit, the sealing function of the valve body 69 is maintained. Furthermore, blood can be prevented from flowing out even when the wire is pulled out. The front side of such a valve body 69 communicates with the hole 67,
A branched cylindrical portion 64 is formed, and a flushing circuit 90 is provided in this cylindrical portion 64. The flushing circuit 90 includes a tube 91 and a three-way stopcock 92 fixed to the end of the tube 91, and a liquid such as physiological saline or a contrast medium is injected from the end 92a of the three-way stopcock 92.
この場合、前記弁体６９が内腔部６７に設けられている
ので、操作器具の後端からの漏れは生じない。In this case, since the valve body 69 is provided in the inner cavity 67, no leakage occurs from the rear end of the operating instrument.
一方、線材操作ヘッド部材６０（ストレート部６６）の
後部６６ａは、筒状の連結帯７０の前部７０ａと螺合さ

うになっている。On the other hand, the rear part 66a of the wire rod operation head member 60 (straight part 66) is screwed with the front part 70a of the cylindrical connecting band 70, and the rear end of the connecting band 70 has a convex part 75 that projects inward. The convex portion 75 is rotatably engaged with a convex portion 85 provided at the front end of the connecting member 80 as shown. As described above, in the case of this embodiment, the convex portion 75 at the rear end of the connecting band 70 and the convex portion 85 provided at the front end of the connecting member 80 form a connecting unit. This allows the wire rod and the catheter to rotate relatively independently, as in the case of the second embodiment.

るという効果を奏する。The wire handling instrument of the present invention includes a wire clamping part that can arbitrarily clamp a wire, a catheter fitting part that fits and is integrated with the base of the catheter, and a gripping part that can grip.
The catheter and the wire manipulating device can be integrated as appropriate, allowing easy operation with one hand, for example. Further, since the wire rod handling instrument of the present invention has a substantially cylindrical gripping portion, delicate rotational operation is possible when gripped with fingers or the like. Further, the wire rod handling instrument of the present invention includes a wire rod held by the wire rod holding part,
The catheter has a connecting part that can rotate relatively independently of the catheter fitting member into which the base of the catheter is fitted, making it easy to select the blood vessel to be inserted. Blood vessels can be easily selected even if the In addition, the wire manipulating device of the present invention is provided with a valve body in the hole of the wire manipulating device, and a flushing circuit connected to the hole and branching from the hole and extending outward. Flushing is possible and the occurrence of blood clots can be prevented. In addition, if the amount is small, contrast imaging can be performed without removing the wire.
