The number of the first functional cavity and the third functional cavity mentioned in the above embodiments is not limited, and may be selected according to the severity of the lesion and the degree of adverse reaction of the patient, and the number of the first functional cavity may be set to 2-3, and the number of the third functional cavity may be set to 1-2.
The hardness of the catheter body 100 in the above embodiment is greater than that of the conduit formed by the internal functional cavity, and the catheter body 100 with certain hardness is more convenient for the intubation tube to reach the predetermined treatment position when in use.
When the embodiment provided by the invention is used for treating a patient with digestive tract tumor, the embodiment provided by the invention is inserted into a nasal cavity, the proximal end of the catheter body 100 is sent to a jejunum position, food emulsion is pumped inwards from the distal end of the second functional cavity 102 in the catheter body 100 and enters the jejunum from the proximal end of the catheter body 100 to provide nutrition for the patient, the proximal end of the third functional cavity 103 is sent into a stomach, a negative pressure suction apparatus is connected to the distal end of the third functional cavity 103 to draw out digestive juice through the first side hole 104, nausea and vomiting caused by reflux of the digestive juice (such as gastric juice) are prevented for the patient, referring to fig. 9, a radioactive particle strip is implanted into a certain position of the first functional cavity 101 according to a lesion position calculated in advance and sent to the position of a tumor lesion 601 of the digestive tract 600, and the tumor lesion 601 is treated by near-distance chemotherapy. Since the radioactive particles themselves are developed under X-rays, the tubes can be directly put down under X-ray conditions.
In conclusion, the invention can achieve a plurality of functions of tumor treatment, nutrition regulation, gastric acid suction, diagnosis and the like simultaneously by only one catheter; the product can be detachably combined with an external apparatus for use, so that a patient does not need to carry the external apparatus all the time, the normal activity of the patient is not influenced, and the comfort level of the patient is improved; the radioactive particles are implanted in the catheter, and after treatment is finished, the radioactive source is detached and removed out of the body along with the catheter, so that the device is safe and efficient. In addition, the product has simple structure, convenient operation, no need of additional equipment support, easy popularization and high application value for the on-site treatment of the alimentary canal tumor.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
