Abstract
The utility model discloses one can retained type Intraoperative biliary tract contrast catheter.It includes the hollow tube being made up of medical plastic, and the upper end of hollow tube has funnelform opening, and the lower end of hollow tube has the tip of semicircular arc；The latter half of hollow tube has rough surface；The inclined hole of the most advanced and sophisticated side being positioned at semicircle arcuation it is provided with on the sidewall of hollow tube.The utility model has the advantage of: can ensure that this angiography catheter is connected with the fixing of gallbladder neck tube, difficult drop-off, additionally, the hollow tube using medical plastic to make makes can not only be used for the guide wire of intra-operative cholangiography pipe and uses, also can use as cholangiography pipe, as art can not have residual stones in getting rid of common bile duct completely, then need in gallbladder neck tube this angiography catheter of indwelling, to facilitate postoperative radiography, furthermore, the scale arranged can facilitate medical worker to know, and conduit inserts the length of gallbladder neck tube, depending on art finds the lesion degree of gallbladder neck tube, improve the reliability of use.
Description
Technical field
This utility model relates to a kind of cholangiography conduit, specifically one can lead by retained type intra-operative cholangiography
Pipe, belongs to technical field of medical instruments.
Background technology
Cholangiography conduit is mainly used in the art of operation on biliary tract (include laparoscopic biliary tract operation and open abdomen operation on biliary tract)
Cholangiography and postoperative biliary drainage.The Chinese utility model patent application of Patent No. ZL200420089466.5 discloses one
Plant dual-purpose Intraoperative biliary tract contrast catheter, on the one hand, this conduit is directly disposed as hard tubule, and surface unusual light, by this conduit
When fixing with gallbladder neck tube, in the easy landing of conduit to abdominal cavity, it is impossible to play the effect of drain；Still further aspect, cholangiography
The degree of depth that conduit inserts is difficult to ensure, have impact on the reliability of use.
Summary of the invention
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure design, is widely used, and difficult drop-off makes
Can retained type Intraoperative biliary tract contrast catheter with effective.
In order to solve above-mentioned technical problem, of the present utility model can retained type Intraoperative biliary tract contrast catheter, including by medical
The hollow tube that plastics are made, the upper end of hollow tube has funnelform opening, and the lower end of hollow tube has semicircular arc
Tip；The latter half of hollow tube has rough surface；The point being positioned at semicircle arcuation it is provided with on the sidewall of hollow tube
The inclined hole of end side.
Further, a diameter of 15mm of described hollow tube.
Further, the distance between described inclined hole and tip is 5mm.
Further, described medical plastic is PE, PP, PET or PU plastics.
Further, a length of 90mm of described rough surface.
Further, the roughness of described rough surface is 3-6 times of hollow tube wall roughness.
Further, described hollow tube is provided with a plurality of graduation mark from point upward arrangement.
Further, the spacing between graduation mark described in each bar is 10mm.
The utility model has the advantage of: due to the most advanced and sophisticated hollow pipe with funnelform opening and semicircular arc arranged
Body, the latter half of hollow tube has rough surface, thus can ensure that the fixing company of this angiography catheter and gallbladder neck tube
Connect, difficult drop-off, it addition, the hollow tube using medical plastic to make makes can not only be used for the guide wire of intra-operative cholangiography pipe
With, it is possible to use as cholangiography pipe, as art can not have residual stones in getting rid of common bile duct completely, then need to be at gallbladder neck tube
This angiography catheter of middle indwelling, to facilitate postoperative radiography, furthermore, the scale of setting can facilitate medical worker to know conduit insertion gallbladder
The length of capsule neck tube, depending on finding the lesion degree of gallbladder neck tube in art, improves the reliability of use.
Accompanying drawing explanation
Fig. 1 is that this utility model can the structural representation of retained type Intraoperative biliary tract contrast catheter.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, to of the present utility model can retained type Intraoperative biliary tract contrast catheter make into
One step describes in detail.
As it can be seen, of the present utility model can retained type Intraoperative biliary tract contrast catheter, including use medical plastic (such as
PE, PP, PET, PU etc.) hollow tube 3 made, the hollow tube that its medical plastic is made has certain hardness, uses medical
Plastics make make its can indwelling in biliary tract；The upper end of hollow tube 3 has funnelform opening 1, and funnelform opening 1 can connect
Syringe, is used for injecting contrast agent；The lower end of hollow tube 3 has the tip 2 of semicircular arc；This tip can be inserted into gallbladder neck tube
One end, a diameter of 15mm of hollow tube 3, the total length of hollow tube 3 is 650mm；It is provided with on the sidewall of hollow tube 3
Being positioned at the inclined hole 4 of the side, tip 2 of semicircle arcuation, the distance between described inclined hole 4 and most advanced and sophisticated 2 is 5mm, specifically it with
Most advanced and sophisticated relative one end is provided with opening, connects for syringe, and contrast agent is injected biliary tract from this opening by syringe；Hollow pipe
Having rough surface 5 on the latter half wall of body 3, a length of of rough surface 5 starts upwards 90mm from tip specifically
Length, the roughness of rough surface 5 is 3-6 times of hollow tube other parts wall roughness, and its roughness is much larger than leading
Other wall of pipe, it is ensured that this angiography catheter is connected with the fixing of gallbladder neck tube, thus can be when being connected with gallbladder neck tube
Increasing friction force, prevents this angiography catheter from coming off from gallbladder neck tube.
Further, described hollow tube 3 is provided with a plurality of graduation mark 6 from point upward arrangement, each bar scale
Spacing between line 6 is 10mm, say, that every one graduation mark 6 of 10mm labelling from most advanced and sophisticated 2, altogether labelling 100mm length,
To facilitate operator to know, angiography catheter inserts the degree of depth of gallbladder neck tube, and depending on finding the lesion degree of gallbladder neck tube in art, this is made
Shadow conduit can not only be used for the guide wire of intra-operative cholangiography pipe and uses, it is possible to use as cholangiography pipe, as can not be complete in art
Get rid of in common bile duct and have residual stones, then need in gallbladder neck tube this angiography catheter of indwelling, to facilitate postoperative radiography.
