Abstract

An apparatus for a transluminal procedure includes: a case composed of a front case part formed in the shape of a pipe and having a locking groove at a rear end, a central case part combined with the front case part and having a button hole at a rear end, and a rear case part combined with the central case part and having a through-hole formed ahead of a button groove coming in contact with the button hole at a center; a locking member having a button and a locking end; an operation member formed in the shape of a pipe and moving up and down in the case; an inner wire in live operation member and locked to the case; and an outer tube fitted on the inner wire and fixed ahead of the operation member.

Claims

1. An apparatus for a transluminal procedure, wherein a case is composed of a front case part formed in the shape of a pipe and having a locking groove at a rear end of the front case, a central case part combined with the front case part and having a button hole at a rear end of the central part, and a rear case part combined with the central case part and having a through-hole and a button groove being in contact with the button hole to receive a button,

the button protrudes rearward from a locking end inserted in the through-hole, the button is supported by an elastic member disposed in the button groove of the rear case part, returns after being pressed, and constitutes a locking member having the locking end, an operation member is formed in the shape of a pipe and moving up and down in the case, an inner wire is inserted in the operation member and locked to the case, and

an outer tube is fitted on the inner wire and fixed to a front end of the operation member.

2. The apparatus for a transluminal procedure of claim 1, wherein the operation member includes a cap attached and detached to and from an upper portion of a long body pipe.

3. The apparatus for a transluminal procedure of claim 2, wherein the long body pipe of the operation member has a wire hole formed through a center of a front portion, a cut portion is formed longitudinally rearward in the operation member to communicate with the wire hole, and a plurality of locking step grooves that is locked to the locking end of the locking member is formed along a cut line at a side of the cut portion.

4. The apparatus for a transluminal procedure of claim 3, wherein a seat expanding in an area larger than the cut portion is formed adjacent to the wire hole through which the inner wire passes in the cut portion, and a stopper formed in a rectangular shape with a slit is fitted in the seat.

5. The apparatus for a transluminal procedure of claim 4, wherein a plurality of guide grooves are formed longitudinally formed to face each other on both inner sides, respectively, of the cut portion.

6. The apparatus for a transluminal procedure of claim 5, wherein an outer side of an elastic member including a spring inserted in the cut portion is supported by the guide grooves.

7. The apparatus for a transluminal procedure of claim 1, wherein a locking portion is integrally fixed at an end of the inner wire that passes through the operation member to be locked to the locking groove of the front case part.

8. The apparatus for a transluminal procedure of claim 7, wherein a rear portion of the inner wire passing through the operation member is a wire integrally combined with a locking block, and a plate-shaped wire is integrally formed a front end of the wire and connected with a front tube tip.

9. The apparatus for a transluminal procedure of claim 1, wherein a plurality of tongs are connected to the inner wire and a tongs body where the plurality of tongs are disposed is connected to the outer tube to function as forceps.

10. The apparatus for a transluminal procedure of claim 1, wherein a snare is connected to the inner wire to move into and out of the outer tube.

11. The apparatus for a transluminal procedure of claim 1, wherein the outer tube is composed of a front tube tip and a rear tube, the front tube tip connected to a front of a variable portion, which is made of an elastic member and contracts and increases in diameter when being pulled, is connected with an end of the inner wire and the rear tube connected to a rear of the variable portion is fixed to a front end of the operation member.

12. An apparatus for a transluminal procedure, wherein a case is composed of a front case part formed in the shape of a pipe and having a locking groove at a rear end of the front case, a central case part combined with the front case part and having a button hole at a rear end of the central case, and a rear case part combined with the central case part and having a through-hole formed and a button groove being in contact with the button hole to receive a button,
