Abstract
The utility model relates to a knub positioning air chamber in the alimentary tract metal bracket implantation technique, and includes a guide tube, an air chamber, a thread eye positioned at the front end of guide tube, a contrast agent outlet positioned behind the air chamber, an air chamber pipe put inside the guide tube, a thread guiding tube and a contrast pipe, the tail end of air chamber pipe is arranged with an air chamber valve. The utility model is characterized in that the contrast agent outlet is positioned behind the air chamber. The positioning air chamber can pass the tong path of the original inner lens under the uncharged status; after the air chamber is charged, the contrast agent can flow out from the side holes of guide tube behind the air chamber, then the contrast agent is not easy to be drained away, so that the judgment for straitness degree and scope of the knub can be more accurate, the choice of the diameter and the length of bracket can be more applicable, and the putting position of bracket can be guided more accurately; the soft degree of air chamber is good, the pain of patient is light; thereby the utility model is suitable for the whole alimentary tract knub; and the positioning air chamber can also be used in other fields such as alimentary tract contrast, expansion and decompression and so on; the instrument is convenient in application, simple in operation and easy in mastering.
Description
Technical field
This utility model relates to the tumor-localizing air bag in a kind of digestive tract metal rack implantation.
Background technology
The malignant tumor of digestive tract sickness rate accounts for 1/2 of China's malignant tumor, and it is narrow that late tumor patient often merges digestive tract, and intestinal obstruction etc. is taken food, caused in influence.Many in the past employing palliative operation treatments, the operation risk height, the patient suffering is big.The digestive endoscopy technology develops rapidly in recent years, and metal rack is inserted and can be solved the narrow problem of tumor, and is simple, convenient, painful few.But the digestive tract metal rack is inserted in the process at present, the not fine as yet solution of the accurate orientation problem of tumor narrow (often since the contrast agent underfilling or run off too fast due to), especially for duodenum and large bowel neoplasm, concrete narrow position and narrow length are difficult to be held, and the selection that influences metal rack length reaches accurately puts.
Summary of the invention
The purpose of this utility model provides the tumor-localizing air bag in a kind of digestive tract metal rack implantation in order to overcome the above-mentioned deficiency of prior art, can judge the degree and the scope of tumor narrow comparatively accurately, and the location is put more accurately convenient.
This utility model is realized by following measure:
Tumor-localizing air bag in a kind of digestive tract metal rack implantation comprises conduit, air bag, thread eye, contrast agent outlet, air bag valve, seal wire, it is characterized in that catheter interior contains airsac tube, wire leading pipe and radiography pipe; The head of conduit one end is the outlet thread eye of wire leading pipe; One air bag is arranged on the thread eye rear tube, and air bag is passed by conduit, and its two ends are fixed on the periphery of conduit, and airsac tube outlet is arranged on the air bag inner catheter; The outlet of one contrast agent is arranged on the conduit of air bag rear; The other end of conduit is three pipes after separately, is respectively airsac tube, wire leading pipe and radiography pipe; Wire leading pipe an end for being positioned at supravasal thread eye, wire leading pipe inside is penetrated with a seal wire; There is an air bag valve termination of airsac tube, and the other end of airsac tube is the airsac tube outlet in the air bag; One end of radiography pipe is for being positioned at supravasal contrast agent outlet.
Tumor-localizing air bag in this utility model digestive tract metal rack implantation, comprise conduit, air bag, be positioned at the thread eye of catheter proximal end, the contrast agent outlet that is positioned at the air bag rear, the airsac tube that places catheter interior, wire leading pipe, radiography pipe form, described airsac tube end has an air bag valve.The design's special feature is: the contrast agent outlet is positioned at the air bag rear.This positioning gasbag can pass through scope (gastroscope or intestinal mirror etc.) inherent pincers road under the unaerated state; Behind the airbag aeration, contrast agent flows out from the conduit side opening of air bag rear, and contrast agent is difficult for running off, and judges that tumor narrow degree and scope are more accurate, selects the diameter and the length of support more suitable, and the position of instructing support to put is more accurate; The air bag pliability is good, and patient's misery is little; Be suitable for the all-digestive tract tumor; This positioning gasbag still can be used for other fields such as gastrointestinal image, expansion, decompression; This instrumentation is convenient, and is simple to operate, is easy to grasp.
Description of drawings
Fig. 1 is the structural representation of this utility model tumor-localizing air bag
Fig. 2 is that this utility model tumor-localizing air bag A-A is to cutaway view
Among the figure: conduit 1, airsac tube 2, radiography pipe 3, wire leading pipe 4, thread eye 5, air bag 6, airsac tube outlet 7, contrast agent outlet 8, air bag valve 9, seal wire 10.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is made specific description.
As depicted in figs. 1 and 2, tumor-localizing air bag in the digestive tract metal rack implantation of the present utility model, comprise conduit 1, be positioned at the thread eye 5 of catheter proximal end, be positioned at the air bag 6 of catheter proximal end, be positioned at the airsac tube outlet 7 on the air bag inner catheter, be positioned at the contrast agent outlet 8 at air bag rear, be positioned at three pipes that separate of the conduit other end, be respectively airsac tube 2, wire leading pipe 4 and radiography pipe 3, there is an air bag valve 9 termination of airsac tube, and wire leading pipe inside is penetrated with a seal wire 10.
During use with digestive endoscopy (as gastroscope or intestinal mirror) near the digestive tract tumor narrow positions, earlier an end of seal wire 10 is crossed the narrow positions far-end by endoscopic forceps channel, the other end by this seal wire enters wire leading pipe by thread eye 5 again, and guiding positioning gasbag 6 is by the tumor narrow positions.Open air bag valve 9, by the airsac tube inflation, gas enters air bag through airsac tube outlet 7 and makes airbag inflation, the digestive tract of complete closed tumor far-end.Inject contrast agent by radiography pipe 3, contrast agent is flowed out by the contrast agent outlet 8 of air bag rear end, makes the digestive tract of its complete filling tumor locus.Give external X line perspective this moment again, can see that then narrow positions is obvious filling defect, get final product clear and definite tumor narrow positions and stenosis and length, the exact position that and guides support to put.After this can select the metal rack of suitable diameter and length, the row metal support of going forward side by side is inserted.
The utlity model has following advantage: (1) this positioning gasbag can pass through scope under the unaerated state (gastroscope or intestines mirror etc.) intrinsic pincers road; (2) behind the airbag aeration, contrast preparation is from air bag rear conduit side opening The middle outflow, contrast preparation are difficult for running off, and judge that tumour narrow degree and scope are more accurate, the selection support Diameter and length are more suitable, and the position of instructing support to put is more accurate; (3) the air bag pliability is good, disease People's misery is little; (4) the air bag maximum gauge can reach 5cm, is suitable for the all-digestive tract tumour; (5) this location gas Capsule still can be used for the other fields such as gastrointestinal image, expansion, decompression; (6) this instrumentation is convenient, operation Simply, be easy to grasp; Easily manufactured, low price is easy to large-scale production.
