A kind of embodiment 2: airway wall intervention traction attachment
It is used in interventional therapeutic technique for cooperating bronchoscope, is auxiliarily fixed and pulls out phlegm bolt, phlegm scab, take out behaviourMake simply, efficiently, it is all fine for the phlegm body or loose phlegm body effect that are condensed into phlegm scab.
On the basis of 1 structure of embodiment, specific difference is its specific structure,
The connection type of adjustment part 3 and built-in pipe 1, is changed to linear slide by being threadedly engaged before difference 1), specifically:
Setting straight in direction is extended along on the side wall of the built-in pipe 1, the straight is arranged in mounting base 5Between head 2, the inner ring inner wall of the preceding adjustment part 3 is equipped with the sliding block cooperated with straight, thus, preceding adjustment part 3It can be slid back and forth along the length direction of built-in pipe 1 in the front end of built-in pipe 1.That is, preceding adjustment part 3 is close to rear adjustmentIn the traveling process of part 6, the circumferential relative position of the two does not change.
Difference replaces with flexible bandlet 12, includes specially that single layer is set according to model 2) by the flexible filaments 7 in embodiment 1It sets, alternatively, the flexible bandlet 12 of the double-deck setting.By taking the flexible bandlet 12 of bilayer setting as an example:
It include internal layer bandlet and outer layer bandlet, the internal layer bandlet and outer layer bandlet are respectively around 1 circular array of built-in pipeColumn.
Above-mentioned difference bring effect is, current adjustment part 3 under the traction of the traction wire, close to rear adjustment part 6 whenIt waits, the flexible bandlet 12 of this example built-in pipe 1 only arches upward to two sides, block piece is formed, without twisting.
When specific operation, difference is, needs the front of this built-in pipe 1 through target phlegm bolt, phlegm scab, position is until rearAdjustment part 6 is located at outside the edge of front side (far from fore side) of phlegm bolt, that is, rear adjustment part 6 runs through from phlegm bolt, phlegm scab completelyIt goes out.
In this way, forming a plate-like block piece after flexible bandlet 12 arches upward in the operation contralateral side of target phlegm body, leading backwardWhen drawing taking-up built-in pipe 1, it will be able to take phlegm body out of, effect is very good.
