Abstract
The utility model relates to a local chemotherapy device for esophagus cancer, which belongs to the technical field of medical instruments. The utility model provides a local chemotherapy device for esophagus cancer, which is used for directly implementing chemotherapy to the focus of an esophagus tumor. The utility model is characterized in that the local chemotherapy device for esophagus cancer is composed of a medicine injecting tube, a framework guiding tube, an upper ball bag with a ventilating tube and a lower ball bag, wherein the framework guiding tube penetrates from the upper and the lower ball bags, the medicine injecting tube penetrates through the upper ball bag and the outlet end of the medicine injecting tube is positioned between the upper and the lower ball bags. The skeleton guiding tube can be slid along a metallic guiding wire to send the device to the focus position of esophagus. The upper and the lower ball bags are fixed on the upper end and the lower end of the tumor focus in the way that air is inflated in the ball bags or liquid is injected in the ball bags, and then physic liquor is injected in a lacuna enclosed by the upper and the lower ball bags, an esophagus pipe wall and the tumor by the medicine injecting tube. Because medicine is directly acted on the focus position, the utility model has the characteristics of high therapeutic effects, light bad reactions of patients, etc. Because the structure of the utility model is designed in a tube bundle shape in order to adapt to esophagus, the utility model has the characteristics of easy sending and little pain of medicine application and is suitable for being used as a preferred instrument for the chemotherapy of esophagus cancer.
Description
Technical field
This utility model relates to the utensil to tube chamber tumor focus local chemotherapy, belongs to the medical apparatus technical field.
Background technology
At present, clinical method to the esophagus malignant tumor chemotherapy is identical with other cancers with approach, all is to adopt intravenous chemotherapy.Adopt this kind embolic chemotherapy, medicinal liquid plays a role by blood circulation, and the untoward reaction that chemotherapy produces is strong, and side effect is big, often causes patient's body weak more; Simultaneously, because medicine can not directly act on lesions position, so curative effect is also not satisfactory.If suitable utensil can be provided, directly the esophageal tumor focus be implemented targeted chemotherapy and should be an effective treatment approach.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of esophageal carcinoma local chemotherapy device from chemotherapy to the esophageal tumor focus that directly implement.
The alleged problem of this utility model realizes with following technical scheme:
A kind of esophageal carcinoma local chemotherapy device has medicine-pouring pipe, skeleton conduit and has the last sacculus and the following sacculus of breather in the formation, the body of skeleton conduit passes from upper and lower sacculus, and medicine-pouring pipe passes sacculus, and the port of export of medicine-pouring pipe is between upper and lower sacculus.
Above-mentioned esophageal carcinoma local chemotherapy device has seal wire in the described skeleton conduit 2.
Skeleton conduit of the present utility model can slide along wire guide, this device is delivered to the lesions position of esophagus.By inflation in sacculus or injection liquid, make upper and lower sacculus be fixed on the upper and lower end of tumor focus, by medicine-pouring pipe medicinal liquid is injected the lacuna that upper and lower sacculus and esophageal wall and tumor surround then.This administering mode is compared with the venous transfusion chemotherapy, has medicine and directly acts on lesions position, curative effect height, characteristics such as adverse reactions of patients is light.On structural design, be bundle shape for adapting to esophagus, have be easy to send into, the painful few characteristics of dispenser, suitable first-selected utensil as the esophageal carcinoma chemotherapy uses.
Description of drawings
Fig. 1 is this utility model structural representation.
Numbering submeter representative in the accompanying drawing: sacculus, 7-esophageal wall and tumor, 8-blow vent under 1-medicine-pouring pipe, 2-skeleton conduit, 3-breather, the last sacculus of 4-, 5-seal wire, the 6-.
The specific embodiment
This utility model is mainly by investing skeleton supravasal pair of sacculus, medicine-pouring pipe and the pipeline of inflation being formed.This device is closed in the esophageal neoplasm position by two sacculus with chemotherapeutics, promotes the absorption of tumor to medicine by heating such as radio frequencies, reaches the purpose of treatment tumor.
Consult Fig. 1, medicine-pouring pipe 1, skeleton conduit 2 and breather 3 are the boundling shape and are fixed in the sacculus 4, and skeleton conduit 2 passes through down sacculus 6 simultaneously.Breather 3 communicates with last sacculus 4 and following sacculus 6 simultaneously, and the breather 3 in the last sacculus 4 is provided with blow vent 8, end outlet is arranged in sacculus 6 down.The dispenser mouth of medicine-pouring pipe 1 is aimed at lesions position between upper and lower sacculus.Medicine-pouring pipe, skeleton conduit and breather are flexible pipe, and the seal wire in the skeleton conduit is a tinsel.Last sacculus 4 and following sacculus 6 are spherical air bag.During use under the demonstration of observation instrument is instructed, earlier seal wire is inserted gastric by mouth or nasal cavity, skeleton conduit 2 enters intraesophageal appropriate location along seal wire 5 then, and injecting gas or liquid make two inflation, make it be fixed on the tumor focus upper and lower side, and be close on the esophagus tube wall.Afterwards, inject chemotherapeutics by medicine-pouring pipe 2 to lesions position.Chemotherapeutics available support liposome or albumin wrap up, and mix with the temperature-sensitive nano material, improve the heating-up temperature of radio frequency to tumor by local, promote the absorption of tumor to medicine.Treatment finishes, and sacculus 4 and following sacculus 6 are lost heart, and takes out therapy equipment.
