Abstract
The utility model relates to the field of medical instrument technology, more particularly to a kind of elbow mesh basket, it is accurate at the top of sheath that the sheath setting of elbow structure can make, it is convenient, quickly enter in bile duct at an acute angle between duodenum, then it in release target seeker carries out that stone is taken to operate, sheath is avoided without radian, it is more difficult when insertion, especially papillary section is smaller, when operator's experience is not abundant, the broken cause perforation out of mesh basket head end easily occurs, bile duct then conveniently can be smoothly inserted into head Prebending type sheath to carry out taking stone, not only accelerate operative speed, shorten the painful time of patient, the safe coefficient to patient is also considerably increased simultaneously, good application effect.
Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of elbow mesh baskets.
Background technique
In general, with choledochus, ductuli hepaticus communis, left and right calculus of hepatic duct patient, usually will appear diarrhea, obstructive jaundice and
The clinical symptoms such as fever.For the patient for being reluctant to operate or have operation taboo, recurrence after operation, postcholecystectomy etc., adopt
It is first choice with treatment ERCP (taking out treatment by duodenoscope row calculus of bile duct).Frequently with therapeutic device be bile duct
Calculus stone extraction basket, the stone extraction basket sheath being made of plastics inside are installed with drawing steel wire, and take with what drawing steel wire was connected
Stone mesh basket handle and stone extraction basket are constituted.But the front end of the general stone extraction basket for biliary tract stone extraction does not have specially treated,
Be not during being inserted into biliary tract often it is much smoother because at an acute angle between duodenum and choledochus, be easy to meeting
Stone extraction basket is mistakenly inserted in ductus pancreaticus, operating time is increased, causes unnecessary security risk.
Publication number CN204765805U, discloses a kind of stone extraction basket with elbow, and target seeker is designed to elbow shape,
But after target seeker reaches ductus choledochus nearby, what curved target seeker still will be extended into bile duct, it is bent during elongation
Target seeker can bring sense of discomfort, especially papillary section smaller to patient, when operator's experience is not abundant, easily generation mesh basket
Head end is broken to be gone out to cause perforation.
Publication number CN205458904U discloses a kind of stone extraction basket device and publication number CN105982716B mono-
Kind of stone extraction basket, is straight peen mesh basket, be not during being inserted into biliary tract often it is much smoother, increase operating time and difficulty
Degree.
Utility model content
Technical problem to be solved by the utility model is: being brought not to solve the meeting of above-mentioned curved target seeker to patient
Suitable sense, and mesh basket head end broken the technical issues of causing perforation out occurs, the utility model provides a kind of elbow mesh basket.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of elbow mesh basket, including mesh basket ontology,
Push-pull rod, sheath and target seeker, the target seeker are fixedly connected with the top of mesh basket ontology, the end of mesh basket ontology and push-pull rod
Top connection, the end of push-pull rod is connected with operation handle, and sheath is sleeved on the outside of mesh basket ontology and push-pull rod, the sheath
The top of pipe is in elbow shape, and the top of target seeker is in arc-shaped, and the mesh basket ontology is taken in sheath when not working, in work
When making, mesh basket ontology is co-operated to drive by operation handle and push-pull rod to be stretched out outside sheath.
Further, the angle of bend on the sheath top is 120 ° -140 °, and target seeker length is 1-3mm.Target seeker is substantially
Button shape is proposed in top arc shape, when lesser volume enables to target seeker to work, reduces the feeling of pain to patient, and
Convenient for guaranteeing the smoothness of target seeker work.
After taking stone due to spherical mesh basket, rubble is easy to fall, and therefore, the mesh basket ontology is stainless steel wire, twine number
Amount is 3-8 root, and the distracted shape of mesh basket ontology is loose twisted shape.
The utility model has the beneficial effects that the elbow mesh basket of the utility model, the sheath setting of elbow structure can make
Accurately, easily and efficiently enter in bile duct at an acute angle between duodenum at the top of sheath, is then releasing target seeker progress
It taking stone to operate, avoids sheath without radian, when insertion, is more difficult, and especially papillary section is smaller, when operator's experience is not abundant,
Mesh basket head end easily occurs and breaks to cause perforation, bile duct then conveniently can be smoothly inserted into head Prebending type sheath and carries out taking stone, no
Operative speed is only accelerated, the painful time of patient is shortened, while also considerably increasing the safe coefficient to patient, using effect
Fruit is good.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram before the utility model elbow mesh basket is released.
Fig. 2 is the structural schematic diagram after the utility model elbow mesh basket is released.
In figure: 1, mesh basket ontology, 2, push-pull rod, 3, sheath, 4, target seeker, 5, operation handle.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
It as illustrated in fig. 1 and 2, is the utility model optimum embodiment, a kind of elbow mesh basket, including mesh basket ontology 1, push-pull rod
2, sheath 3 and target seeker 4, target seeker 4 are fixedly connected with the top of mesh basket ontology 1, the end of mesh basket ontology 1 and push-pull rod 2
Top connection, the end of push-pull rod 2 are connected with operation handle 5, and sheath 3 is sleeved on the outside of mesh basket ontology 1 and push-pull rod 2, sheath
The top of pipe 3 is in elbow shape, and the top of target seeker 4 is in arc-shaped, and mesh basket ontology 1 is taken in sheath 3 when not working, in work
When making, mesh basket ontology 1 is co-operated to drive by operation handle 5 and push-pull rod 2 to be stretched out outside sheath 3.The angle of bend on 3 top of sheath
It is 120 ° -140 °, 4 length of target seeker is 1-3mm.Mesh basket ontology 1 is stainless steel wire, and twine quantity is 3-8 root, mesh basket ontology 1
Distracted shape is loose twisted shape.
When stone being taken to operate, first controls operation handle 5 and take in mesh basket ontology 1 in sheath 3, by sheath 3 through duodenum
When being inserted into ductus choledochus, by adjusting the direction of 3 top elbow structure of sheath and cooperating rotation under mirror, so that elbow direction is rectified
It is directed at ductus choledochus well, so gos deep into the utility model, then the entrance that the sheath 3 of elbow leads mesh basket ontology 1 quick and safe
To ductus choledochus entrance, is co-operated by operation handle 5 and push-pull rod 2 mesh basket ontology 1 is driven to stretch out outside sheath 3 later, stretched out
Target seeker 4 does not have warp architecture in journey, and end is in arc-shaped, and small in size, when insertion smoothly, especially papillary section compared with
Small, mesh basket ontology 1, which is also less prone to brokenly, to be gone out to cause perforated phenomenon.Operative speed is not only accelerated, the painful time of patient is shortened,
The safe coefficient to patient, good application effect are also considerably increased simultaneously.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
