Step 5：Unnecessary web material is wiped out, string bag near-end is enclosed on heat-shrink tube, glued on pyrocondensation, heat-shrink tube by first
Adapter, the second bonding pipe and the string bag are strengthened being secured together, so as to form recover head.
Wherein in step 1, using moulds of industrial equipment thermal finalization mode.
Recover head specifically makes and application method：
The distal end of the string bag uses binding mode, and web material is fixed on to the distal end of lasso, and lasso interts through the string bag successively, closely
End respectively covers one-step polymerization thing sleeve pipe on the both sides of lasso, after lasso is closed up, by string bag hot pressing on this polymer, now, net
Together with polymer bonding, then the unnecessary web material in lasso upper end is removed, then puts heat-shrink tube, pyrocondensation, now net is by jail
The near-end of lasso is fixed on firmly.
After the string bag is made, then with drag-line using connecting tube riveting or laser welding, drag-line uses multiply alloy-steel wire group
Into the material has very strong toughness, the string bag can be driven to rotate.Drag-line passes through outer tube, is fixed in near-end on sliding block, drag-line is near
End is connected with boosting bar, in this embodiment, and boosting bar selects square boosting bar, and a rotation is respectively assembled up and down in square boosting bar
Button, upper knob 11 and lower knob 12, two knobs are got up by gluing or ultrasonic bonding, are assembled into a complete knob,
It is square through hole in knob, boosting bar can only longitudinal sliding motion in knob, it is impossible to axial-rotation, and knob can drive boosting bar
Rotation, outer tube 6 is fixed on core bar by nut 8, oral area increase protecting pipe 7.Upon rotation of the knob, it is possible to drive square help
Push rod is rotated, and because square boosting bar is riveted or welded together with drag-line, can thus drive drag-line to rotate, so as to drive
The dynamic string bag is rotated in outer tube, and knob can be rotated with left and right directions.
Device driving drag-line rotary part is square boosting bar, and this connecting rod can only longitudinal sliding motion, it is impossible to axially rotation
Turn, two limited blocks are fixed with square connecting rod, be separately fixed at the two ends of sliding block, sliding block limits the axial direction of square boosting bar
The free degree, square boosting bar can rotate under knob drive, and sliding block drives the axial movement of boosting bar, thus the string bag is opened or
Reclaim.
The string bag product when in use, by the pincers road of scope, reaches foreign matter position, then by moving hand to distal end
Sliding block 13 on handle, the string bag 3 is opened, and drives square boosting bar 10 to rotate by knob, so as to adjust drag-line 9 and string bag side
To then covering taking foreign body, after foreign matter is packaged, sliding block of slowly dropping back slowly draws the string bag in, thus foreign matter can be enclosed on into net
It is then that foreign body is external in pocket.
The utility model provides a kind of medical foreign matter recover, implements the method and approach of the technical scheme very
Many, described above is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection domain of the present utility model.Each part being not known in the present embodiment can use prior art to be subject to reality
It is existing.
