Detailed Description
Specific embodiments of the present invention are described below with reference to the accompanying drawings.
As shown in fig. 1 to 4, the flower-shaped stone removing basket for a soft endoscope according to the present embodiment includes: the stone taking handle 1 is provided with a wave wire slot 13.
The push rod 11, the push rod 11 has metal shrapnel 12, the front end of the metal shrapnel 12 is blocked in the wave slot.
The anti-folding sheath tube 2 is arranged at the front end of the stone taking handle 1.
One end of the sheath tube 3 is fixedly arranged at the front end of the stone taking handle 1 through the anti-folding sheath tube 2, and the sheath tube 3 is matched with an endoscope forceps channel.
As shown in fig. 2, the basket wire group 4 includes three basket wires 41 arranged in a petal shape in the present embodiment. In other embodiments, four petal-shaped mesh basket wires may be used as needed. The basket wires are pre-formed to further assist in forming the basket wire set 4 into a predetermined shape after opening.
The shape and the size of the unfolding of the three groups of circular arcs are controlled by the mutual distance among the connecting pipe, the fixed sliding block, the retainer ring and the front end opening of the sheath tube 3 and the preforming of the steel wire.
As shown in fig. 3, the fixed slide block 7 is arranged in the sheath 3, and three or four groups of double holes are uniformly distributed on the fixed slide block 7. As shown in fig. 5, three groups of double holes are uniformly distributed, wherein one hole is used for fixing one end of one steel wire, and the other hole can be used for allowing the tail of the other steel wire to pass through, and the three groups are respectively corresponding. In fig. 5, the hole from the arrow is a hole for fixing a steel wire, the hole pointed by the arrow is a hole through which the steel wire passes, and the steel wire passes through the hole and is fixedly connected with the following control steel wire rope 5.
And the retainer ring 8 is arranged in the sheath and positioned in front of the positioning slide block.
One end of the control steel wire rope 5 is fixedly connected with the push rod, the other end of the control steel wire rope is fixedly connected with the tail end of the steel wire of the basket steel wire group 4 through the connecting pipe 6, specifically, one end of each basket steel wire is fixed in one of a group of double holes of the fixed sliding block 7, and the other end of each basket steel wire is fixed on the control steel wire rope 5 after passing through one hole.
As shown in fig. 4, in the present embodiment, the metal spring is fixedly installed in the push rod 11, and the body of the push rod 11 is slidably installed in the wave slot. The metal spring sheet is a whole sheet and is V-shaped, and two tips are respectively clamped on the teeth of the front wave wire slot 13 and the rear wave wire slot 13. Thereby preventing the front basket steel wire group 4 from loosening forwards after the stones are sleeved.
Because the metal elastic sheet has elasticity, the push rod 11 can be allowed to push back and forth in the wave slot 13, and meanwhile, because of the elasticity of the metal elastic sheet, after the basket steel wire group 4 at the front end is sleeved with stones, the push rod 11 can pull the control steel wire rope 5 and the basket steel wire group 4 at the front end, so that the basket steel wire group 4 cannot be loosened due to some resistance in the taking-out process.
When in use, the push rod 11 on the handle is pushed forward to drive the control steel wire rope 5 to move the basket steel wire 4 and the fixed sliding block 7 forward synchronously. When the fixed sliding block 7 touches the retainer ring 8, part of the basket steel wires extend out of the pipe sheath 3, the basket steel wire end fixed on the fixed sliding block 7 does not move any more, the push rod 11 is pushed continuously, the unfixed basket steel wire end penetrating through the fixed sliding block 7 moves forward continuously, the steel wires extending out of the pipe sheath 3 are unfolded in an arc shape due to the elastic effect, and three groups of steel wires are unfolded in three arcs to form a petal shape. In other embodiments, when four sets of steel wires are used, the working principle is the same as that of three sets of steel wires, and the description is omitted here. Finally, the connection pipe 6 is stopped by being moved to the fixed sliding block 7. At this time, the basket steel wire group can be used for grabbing the stones.
