Gap is larger, and calculus rubble or muddy stone are easy to leak out from mesh basket, and bile duct wall floccule or attached wall calculus are often adherent
Growth, conventional stone extraction basket take stone operate in be difficult to paste bile duct wall and operated, therefore during taking stone, the three classes situation
It is difficult to clear up or take out.
However, these rubble, muddy stone, bile duct wall floccule or the attached wall calculus that can not take down are easy as calculus
Core may have grown into maximum size again after some time, so that having to carry out surgical calculus removing again, not only cause to patient's body and mind huge
Injury, also increases the medical burden of patient.
Utility model content
The utility model is to carry out in order to solve the above problem, and providing one kind can be in biliary tract stone extraction operation to knot
Stone rubble, muddy stone or bile duct wall floccule or attached wall calculus carry out the biliary tract stone extraction string bag for effectively taking stone.In order to realize
Above-mentioned purpose, the utility model provide following technical solution:
The biliary tract stone extraction string bag provided by the utility model has following technical characteristic: leading including sheath, lithotomy net pocket, fixation
Silk and direction adjust seal wire.Sheath holds the left and right sides to be respectively arranged with the first in command in vitro；Fixed seal wire and direction adjustment are led
Silk is arranged in sheath, and the lithotomy net pocket of end connection in vivo, external end is separately connected second handle and third handle, lithotomy net pocket
Split ring on overlapped adjustment ring, adjustment ring is fixedly connected with internal hold of direction adjustment seal wire；The hole of lithotomy net pocket
Diameter is 0.4~0.6mm.
The biliary tract stone extraction string bag in the utility model is before use, lithotomy net pocket is shunk in sheath, in use, one holds
The first in command of sheath left and right ends is held, another hand is pushed forward second handle and third handle, and lithotomy net pocket is pushed away from sheath
Out, take that rubble is realized in the direction for adjusting lithotomy net pocket when stone by drawing second handle, the net of muddy stone takes and gallbladder
The scraping of tube wall floccule or attached wall calculus.
Further, in the biliary tract stone extraction string bag provided by the utility model, the first in command is detachably connected with sheath, preferably
Sheath is held in vitro is respectively arranged with external screw thread protrusion in left and right sidewall, in a ring, side is provided with tapped the first in command
Connector reuses after realizing the disinfection of the first in command, also reduces the manufacturing cost and use cost of lithotomy net pocket.
Further, in the biliary tract stone extraction string bag provided by the utility model, adjustment ring is mounted on upper part in split ring
On, there are Chong Die with the one third of split ring perimeter.
Further, in the biliary tract stone extraction string bag provided by the utility model, in a ring, third handle is in bar to second handle
Shape facilitates medical staff to distinguish two seal wires.
Further, in the biliary tract stone extraction string bag provided by the utility model, the internal diameter of split ring is 1~1.5cm.
The action and effect of utility model
The biliary tract stone extraction string bag provided by the utility model has the following technical effect that
Since fixed seal wire and direction adjustment seal wire are arranged in sheath, the lithotomy net pocket of end connection in vivo, external end point
Not Lian Jie second handle and third handle, adjustment ring is provided on the split ring of lithotomy net pocket, adjustment ring and direction adjust seal wire
It is internal end be fixedly connected, in taking stone operating process, by pull second handle, the opening direction of lithotomy net pocket can be realized
Adjustment, string bag direction is adjusted according to calculus position to realize, fast and easy carries out net to rubble and muddy stone and takes,
Facilitate the position according to bile duct wall floccule or attached wall calculus, lithotomy net pocket split ring is adjacent to bile duct wall, is realized to bile duct wall
The scraping of floccule or attached wall calculus.
In addition, the aperture due to lithotomy net pocket is 0.4~0.6mm, which can only leak out water, it is ensured that small size
Rubble, muddy stone or unbodied floccule are not leaked out from string bag gap.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the biliary tract stone extraction string bag in the utility model embodiment.
Specific embodiment
The utility model is described in detail below with reference to embodiment and attached drawing.But the following example should not be regarded as to this
The limitation of utility model range.
In the description of the present invention, it should be noted that the orientation of the instructions such as term " on ", "lower", "left", "right"
Or positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description the utility model and simplification is retouched
It states, rather than the device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation,
Therefore it should not be understood as limiting the present invention.
Fig. 1 is the structural schematic diagram of the biliary tract stone extraction string bag in the utility model embodiment.
As shown in Figure 1, the biliary tract stone extraction string bag 100 includes that sheath 1, lithotomy net pocket 2, fixed seal wire 3 and direction adjustment are led
Silk 4.
Sheath 1 is no different with stone extraction basket sheath in the prior art, is had and is inserted into intracorporal internal end and leakage in vitro
External end, the external end left and right sides is symmetrically arranged with the first in command 5.In order to realize the reuse of handle, the present embodiment will
Two first in command 11 are designed to be detachably connected with sheath 1: sheath holds be respectively arranged with external screw thread in left and right sidewall in vitro
