Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind of Medical treatment device removing pancreatic stones
Tool.
Background technology
Clinically, for the calculus in ductus pancreaticus, generally by taking stone air bag, it is scraped from ductus pancreaticus wall
Descend and pull out ductus pancreaticus.The existing stone air bag that takes is that latex declines type sacculus, is made up of gas tube and air bag,
Air bag is positioned at the front end of gas tube.During insertion, first air bag is emptied, then with pusher, air bag is delivered to
Ductus pancreaticus corresponding site, makes the calculus leading edge that air bag is placed in ductus pancreaticus, then gives airbag aeration, and air bag becomes
Spherical, air bag periphery contacts with ductus pancreaticus wall, now, air bag of pulling back, just can will attach to ductus pancreaticus wall
Calculus scrapes and discharges outside ductus pancreaticus.The calculus that this lithotomy balloon device is smooth in being applicable to remove ductus pancreaticus,
But pancreatic stones mostly is zigzag sharp calculus, especially the ductus pancreaticus rubble after extracorporeal shock-wave lithotomy,
Air bag is easy to be cut, and therefore cannot reuse, generally require more renew take stone air bag, this
Result in the waste of apparatus and the increase of medical expense.
There is no a kind of special equipment being applicable to remove zigzag pancreatic stones at present.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, be easy to remove including zigzag calculus
Medical apparatus and instruments by the removing pancreatic stones of filament braiding.
The invention provides a kind of medical apparatus and instruments removing pancreatic stones, by tinsel hollow cylinder, draw
Bar, sleeve pipe form, and described tinsel hollow cylinder is by tinsel and is positioned at two of top and bottom
Quoit forms, and wire rings is woven into hollow cylindrical around two quoits, is wherein positioned at top
Quoit in be provided with cross metal rack；The cross point of described cross metal rack and pull bar
Top fix；Described pull bar is a hard metal thin tube, is placed in sleeve pipe central authorities；Described
The external diameter of tinsel hollow cylinder is consistent with the external diameter of sleeve pipe, is positioned at quoit and the top of sleeve pipe of bottom
End tube wall is fixed.
The medical apparatus and instruments of described removing pancreatic stones, also includes a newel, and described newel is
Hollow cylinder, is positioned at outside pull bar, within sleeve pipe；Described tinsel hollow cylinder is positioned at bottom
Quoit is wound around tinsel；The bottom of the top of newel and tinsel hollow cylinder is fixed.Newel
Effect be to increase mechanical support, in order to during pull bar post-tensioning, tinsel hollow cylinder flattens, and not
Fall into after the meeting.
Described pull bar, its length is more than length and the height sum of tinsel hollow cylinder of sleeve pipe.
Described pull bar, its internal diameter can hold conventional seal wire to be passed through.
Material used by described quoit is slightly coarser than tinsel and is advisable.
The present invention on-demand can make different specifications and models.Preferably, the removing pancreatic stones of the present invention
Medical apparatus and instruments, a length of 2-3cm of tinsel hollow cylinder, a diameter of 2-2.5mm；Pull bar length
For 200-210cm, external diameter is 1.5-1.7mm；Casing length is 180-200cm, and external diameter is 2-2.5mm.
All material selects radiopaque material.
Owing to the cross point of cross metal rack of the present invention is fixed with the top of pull bar, and it is positioned at the end
The quoit in portion top tube wall with sleeve pipe again is fixed；So when pull bar is pulled rearward, pull bar passes through
Tinsel hollow cylinder is compressed by the quoit at tinsel hollow cylinder top, the tinsel of hollow cylinder
To surrounding bulging, until two quoits are collided, now tinsel hollow cylinder is compressed into round pie.
And when pull bar unclamps, the tinsel hollow cylinder compressed recovers former under the effect of tinsel elastic force
Shape, the i.e. present invention are removed the medical apparatus and instruments of pancreatic stones and can be resiled again.
During Clinical practice, routinely the medical apparatus and instruments pusher of the removing pancreatic stones of the present invention is sent
To ductus pancreaticus corresponding site, make the calculus leading edge that tinsel hollow cylinder is placed in ductus pancreaticus, then pull back and draw
Bar, makes tinsel hollow cylinder compression become round pie, is close to ductus pancreaticus wall to tinsel, then
By entirety post-tensioning of the present invention, calculus scraped by ductus pancreaticus wall and pulls out ductus pancreaticus, taking out this most routinely
Remove the medical apparatus and instruments of pancreatic stones.
Present configuration is simple, easy to use, and that can effectively remove including zigzag calculus is various
Pancreatic stones.
