Abstract

The utility model discloses an esophageal or tracheal stent for radiotherapy. The esophageal or tracheal stent comprises a memory stent, a gas bag is arranged on an outer ring of the memory stent, protrusions are arranged at the tail end of the gas bag, stent protrusions are arranged at positions of the memory stent, which correspond to the protrusions, a gas charging balloon is arranged outside the gas bag, and the gas bag is connected with the gas charging balloon through a gas inlet pipe and a gas ventilating tube. Compared with the prior art, the esophageal or tracheal stent for the radiotherapy has the advantages that the silica gel gas bag is arranged outside the memory stent, granular radioactive sources are placed inside the protrusions at the tail end of the gas bag, and the stent protrusions are arranged at the positions of the memory stent, which correspond to the protrusions at the tail end of the gas bag, so that the esophageal or tracheal stent can be well fixed, the radiotherapy can be performed on affected parts, and the discomfort of patients can be reduced.

Description

Radiotherapy esophagus trachea bracket

Technical field

This utility model relates to the internal medicine technical field of medical instruments, particularly a kind of radiotherapy esophagus trachea bracket.

Background technology

The esophageal carcinoma, tracheal neoplasm are China's common malignancy, have formed a plurality of districts occurred frequently in the whole nation, and its sickness rate occupy the first place of various malignant tumor in the district occurred frequently, also are dead major reason, and be very big to the people's harm.The treatment of the esophageal carcinoma, tracheal neoplasm mainly is excision and radiotherapy at present.Because a variety of causes, when most of patient goes to a doctor be in, late period, lost the chance of operation; Radiation, treatment are then by x roentgenotherapia machine, cobalt--equipment such as 60 therapy apparatuss, accelerator for electron therapy carry out external exposure or intra cavitary irradiation, these equipment are because expensive, mostly be equipped in metropolitan large hospital, treatment cycle is also longer, brought inconvenience for outlying district patient's treatment, and intracavitary therapy also needs repeatedly intubate, increased patient's misery.Late esophagus cancer, tracheal neoplasm lose pathological changes such as operator, cardiopulmonary and can not be subjected to operator, recurrence after operation person etc. all can cause esophagus, tracheal stenosis, block, severe patient drinking-water is difficulty all, now unique solution route is to insert esophagus, trachea bracket clinically, esophagus, trachea bracket generally are that Nitinol is made, by memory effect or itself elastic dilatation esophagus, trachea, releasing is blocked, but also only is to have solved diet and breathing problem, and tumor be there is no therapeutical effect.

The China Patent No. application number: 02219530.0 discloses a kind of radiotherapy esophagus trachea bracket, esophagus, trachea bracket and radiotherapy are organically combined, it has the advance for the treatment of, the support effect is namely arranged, be that simple support or radiotherapy are not available, but in use some needs of patients carries out radiotherapy for a long time, needs took out support earlier when this kind support added radioactive source again from patient's esophagus or trachea, increase medical worker's workload like this, increased the subject discomfort sense simultaneously.

Summary of the invention

The purpose of this utility model is that a kind of radiotherapy esophagus trachea bracket will be provided.

For achieving the above object, this utility model is implemented according to following technical scheme:

A kind of radiotherapy esophagus trachea bracket, comprise memory bracket, described memory bracket outer ring arranges air bag, the air bag end is provided with projection, the memory bracket of described protruding correspondence position arranges bracket tab, described air bag arranges inflating balloon outward, is connected with breather by air inlet pipe between air bag and the inflating balloon, and air inlet pipe and breather are for removably connecting.

Further, the sense of discomfort that when using for reducing the patient is caused, described air bag is that silica gel is made.

For reaching better therapeutic effect, can place the granular pattern radioactive source in the projection on air bag, be the treatment at each position of adaptation patient, between described air bag and the memory bracket for being slidingly connected.

Compared with prior art, radiotherapy esophagus trachea bracket of the present utility model, by the silica gel air bag is set outside memory bracket, place the granular pattern radioactive source in the projection of air bag end, the protruding correspondence position of memory bracket and air bag end is provided with bracket tab, can better esophagus or trachea bracket be fixed, and can carry out radiotherapy to the affected part, reduce the subject discomfort sense.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment this utility model is further described, is used for explaining this utility model in illustrative examples and the explanation of this utility model, but not as to restriction of the present utility model.

Radiotherapy esophagus trachea bracket as shown in Figure 1, comprise memory bracket 1, memory bracket 1 outer ring arranges air bag 3, air bag 3 ends are provided with projection 4, the memory bracket 1 of described protruding 4 correspondence positions arranges bracket tab 2, be connected with breather 6 by air inlet pipe 5 between the described air bag 3 outer inflating balloons 7 that arrange, air bag 3 and inflating balloon 7, air inlet pipe 5 and breather 7 are for removably connecting.

Further, the sense of discomfort that when using for reducing the patient is caused, air bag 3 is made for silica gel.

For reaching better therapeutic effect, can place the granular pattern radioactive source in the projection 4 on air bag 3, be the treatment that adapts to each position of patient, between air bag 3 and the memory bracket 1 for being slidingly connected.

By silica gel air bag 3 is set outside memory bracket 1, place the granular pattern radioactive source in the projection 4 of air bag 3 ends, memory bracket 1 is provided with bracket tab 2 with projection 4 correspondence positions of air bag 3 ends, can better esophagus or trachea bracket be fixed, and can carry out radiotherapy to the affected part, reduce the subject discomfort sense; Simultaneously, also can will add the granular pattern radioactive source again after air inlet pipe 5 and breather 7 dismountings as required.

The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model all falls within the protection domain of the present utility model.
