When pressing near projections 28, due to the effect of spring 29, key 27 is rotated backward, and distal ledge 30 returns to limit state.
The application method of the illustrative specimens from pri load-engaging device of the application is as follows:
The specimens from pri load-engaging device is entered in vivo by puncture channel, the movable handle is pushed, stretches the extraction bag
To outside outer tube, under the action of fork-shaped elastic component, extraction bag is opened；
Specimens from pri is extracted, the specimens from pri is placed in the extraction bag；
The movable handle is pulled, until movable handle is pulled out from the outer tube；
The drawstring is pulled, extraction bag is closed；
Outer tube and extraction bag are taken out from puncture channel simultaneously.
When the specimens from pri load-engaging device of the application is in storage or travel position, movable handle 6 is drawn out, and distal end is prominent
Portion 30 stretches out and withstands fixed handle lower cover 22.
Before use, first take out specimens from pri load-engaging device from aseptic packaging, movable handle 6 is pulled out, fork-shaped is made
Elastic component 2 and extraction bag 1 are received into outer tube 3.
Specimens from pri load-engaging device is entered in vivo by puncture channel, movable handle 6 is inwardly pushed, until distal ledge
30 withstand fixed handle lower cover 22 and position.At this point, fork-shaped elastic component 2 is partially released from outer tube 3 and part is opened, make extraction bag
1 sack is opened, and is placed in for specimens from pri.
After the completion of sample extracts, operator presses protruding portion 28, the limit status releasing of key 27, by movable handle 6 to admittedly
Determine to be pushed into handle 5, fork-shaped elastic component 2 is released from outer tube 3, fork-shaped elastic component 2 further opens, 2 root of fork-shaped elastic component
Locate two elastic arms no longer to clamp, to discharge the tongue structure 15 of extraction bag 1.Then by 6 post-tensioning of movable handle, fork-shaped elastic component
2 opening angles become smaller, and the sack of extraction bag 1 is no longer tensioned by fork-shaped elastic component 2 at this time, and tongue structure is from fork-shaped elasticity
The root of part 2 discharges, thus extraction bag 1 is slipped from fork-shaped elastic component 2.Drawstring can be taken from the fixed bit 9 of fixed handle 5 at this time
Under, the lasso trick on drawstring is held, pulls drawstring that the extraction bag sack of distal end is tightened.
The specimens from pri load-engaging device of the application can be used for extracting specimens from pri in surgical operation or take out operation excision
Object, especially for extracting specimens from pri in micro-wound surgical operation or taking out operation excision object.
It should be noted that above-described embodiment is preferred embodiment, related functioning components can be replaced with other component,
Necessary to related unit and module not necessarily the application.Each embodiment in this specification is all made of progressive
Mode describes, and each embodiment focuses on the differences from other embodiments, identical phase between each embodiment
As partially may refer to each other.
