Description

Auxiliary device for applying source after cavity and channel

Technical Field

The utility model relates to a medical apparatus, in particular to a source application auxiliary device after a cavity channel.

Background

Compared with the traditional radiotherapy, the brachytherapy is more and more widely used in tumor radiotherapy due to the advantages of precision, micro-invasion, high efficiency, strong patient profitability and the like, but the traditional post-loading source pipeline needs to be placed in an operation, so that the pain of a patient is increased, and the operation injury is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem to a source auxiliary device is applied after chamber says to provide a chamber, say the opening through the nature chamber and harmless leading-in, carry out the cloth source after arriving the target area, can fall patient's harm to minimum, shortened operation time greatly, reduce the radioactive damage to doctor, and can the accurate source of applying of capacity.

The utility model provides a problem, the technical scheme who adopts is:

the utility model provides a source auxiliary device is executed after chamber way, includes the water injection pipe, has evenly arranged a plurality of source passageways of executing on the pipe wall of water injection pipe, and the water injection pipe divide into anterior canned paragraph and afterbody inflation section, and the front end of anterior canned paragraph is open structure, and the tail end of afterbody inflation section is enclosed construction, and the outer lane of anterior canned paragraph is provided with the lead layer.

Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:

① when the expansion section of the tail part reaches the target area, the water is injected into the water injection pipe at the open end of the front fixing section exposed outside, the expansion section of the tail part is closely attached to the surface of the target area, and the source is distributed through a plurality of source applying channels arranged annularly on the pipe wall, so that the damage of the patient is reduced to the minimum, the operation time is greatly shortened, the radioactive damage to the doctor is reduced, and the source applying can be carried out in sufficient quantity.

② simple structure, convenient use and high practicability.

Preferably, the present invention further provides:

eight source applying channels are uniformly arranged on the wall of the water injection pipe in the circumferential direction.

Drawings

FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

FIG. 2 is a schematic view of the cross-sectional structure A-A of FIG. 1;

FIG. 3 is a schematic view of the cross-sectional structure B-B in FIG. 1;

FIG. 4 is a schematic left side view of the structure of FIG. 1;

in the figure: a water injection pipe 1; a lead layer 2; a source application channel 3; a metal marker 4; metal positioning marks 5.

The specific implementation mode is as follows:

the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.

Referring to fig. 1, 2, 3 and 4, a cavity rear-loading source auxiliary device comprises a water injection pipe 1, eight source applying channels 3 are uniformly arranged on the pipe wall of the water injection pipe 1 in the circumferential direction, the water injection pipe 1 is divided into a front fixing section and a tail expansion section, the front end of the front fixing section is of an open structure, the tail end of the tail expansion section is of a closed structure, a lead layer 2 is arranged on the outer ring of the front fixing section, a metal marker 4 is arranged in the pipe wall of the expansion section of the water injection pipe 1, and a metal positioning marker 5 corresponding to the metal marker 4 is arranged on the outer end face of the water injection pipe 1.

Water injection pipe 1 is formed with the preparation of silica gel hose, during the use, with the leading-in chamber of this device say, after the rear expansion section reachs the target area, at the open end of the anterior canned paragraph of exposing to water injection pipe 1 internal water injection, target area surface is hugged closely after the expansion of rear expansion section, carries out the cloth source through a plurality of channels 3 of giving birth to that the hoop was arranged on the pipe wall.

Through the harmless leading-in of natural chamber way opening, after the afterbody inflation section of water injection pipe 1 reachd the target area, to water injection pipe 1 internal water injection, the target area is hugged closely after the inflation of afterbody inflation section, and water injection pipe 1 terminal can form a plurality of source application passageways 3 in 360, and source application passageway 3 has lead layer 2 to protect at anterior canned paragraph, does not have the lead layer at afterbody inflation section, the utility model discloses can fall patient's damage to minimum, shorten operation time greatly, reduce the radiation damage to the doctor to can the accurate source application of capacity, simple structure, convenient to use, the practicality is strong, can plan 360 interior multiple spot source applications according to the art before the art, can be used to esophagus cancer, rectal cancer, vagina cancer back-loading treatment.

The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
