Abstract
The utility model discloses an implanted source application catheter for radiotherapy. The implanted source application catheter for the radiotherapy is characterized by comprising a catheter with a double-cavity catheter body, the front end of the side cavity of the catheter is formed with an opening while the rear end is provided with a catheter seat, the catheter seat is connected with a side cavity extension tube, the front end of the main cavity of the catheter is formed with a side hole while the rear end is connected with a main cavity extension tube through the catheter seat, a metal push rod is movably mounted in the catheter, the outer diameter and the length of the push rod are matched with those of the main cavity of the catheter, and the push rod is mounted in the main cavity of the catheter. The implanted source application catheter for the radiotherapy is simple in production technique, is low in cost, is simple in structure, is capable of being implanted in the body and lowering the operation complexity of the local radiotherapy, and enables the treating and nursing risk and difficulty to be lowered.
Description
Technical field
This utility model relates to radiation therapy technology field, relates to more specifically a kind of implantation for intracavity local radiotherapy and executes source conduit.
Background technology
Along with the development of radiation therapy technology, the intracavity local radiotherapy demand of internal organs middle and terminal cancer is more and more clinically.The particle of current local radiation treatment is all to use open operation to implant or be injected in vivo with metal needle tubing, and it is large that the former complicated operation and the latter's particle are inserted positioning difficulty, and the nursing of the later stage of two kinds of methods, checks and taking-up particle is all inconvenient to operate.
Utility model content
The purpose of this utility model is exactly the deficiency in order to solve prior art and the one that provides is not only simple in structure, and cost is low, and production technology is simply executed source conduit for radiocurable implantation.
This utility model is to adopt following technical solution to realize above-mentioned purpose: one is executed source conduit for radiocurable implantation, it is characterized in that, it comprises the conduit with two-chamber body, the side chamber front end of conduit is provided with opening, rear end is provided with catheter block, catheter block is connected with side chamber extension tube, the main chamber of conduit front end is provided with side opening, rear end is connected with main chamber extension tube by catheter block, in conduit, be movably set with a metal pushrod, the external diameter of push rod and length are mated with the main chamber of conduit, can be placed into the main intracavity of conduit.
As further illustrating of such scheme, the external diameter of described conduit is 2.5-5mm, and length is 20-50cm, and the quantity of main chamber side opening is 2-5, linearly distributes, and side opening diameter is 0.3-1.5mm.
Described catheter block is with suture needle hole.
Described conduit is that shore hardness is at the medical embedded level of polyurethane, silica gel or the TPE of 40A～75D macromolecule tubing.
The beneficial effect that this utility model adopts above-mentioned technical solution to reach is:
1, the conduit that this utility model adopts not with tissue adhesion, under B ultrasonic or X-ray, can realize visually, when convenient treatment, location, can be implanted in the whole course for the treatment of human body.
2, blind mouthful of main chamber front end, avoids particle to deviate from conduit, and after finishing the course for the treatment of, extracts conduit and can take out particle, and Clinical Processing is convenient and swift.
3, conduit side chamber front opening, rear end connects side chamber extension tube by catheter block, conduit can adopt Seldinger(Sai Erdingge) puncture method utilizes conduit side chamber, along guide wire, conduit is placed to affected part, puts pipe convenient and swift, reduces patient suffering.
4, conduit side chamber can be for injecting contrast agent within the course for the treatment of, and drug irrigation and sampling chemical examination wait operation, avoid second operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is metal pushrod structural representation of the present utility model.
Description of reference numerals: 1, conduit 1-1, side chamber 1-2, main chamber 2, catheter block 3, main chamber extension tube 4, side chamber extension tube 5, side opening 6, metal pushrod.
The specific embodiment
Below in conjunction with specific embodiment, specific embodiments of the present utility model is described in further detail.
As depicted in figs. 1 and 2, this utility model is a kind of executes source conduit for radiocurable implantation, it comprises the conduit 1 with two-chamber body, the side chamber 1-1 front end of conduit 1 is provided with opening, rear end is provided with catheter block 2, catheter block 2 is connected with side chamber extension tube 4, the main chamber of conduit 1-2 front end is provided with side opening 5, rear end is connected with main chamber extension tube 3 by catheter block 2, in conduit 1, be movably set with a metal pushrod 6, the external diameter of push rod and length are mated with the main chamber of conduit, can be placed into the main intracavity of conduit, described catheter block is with suture needle hole.The external diameter of conduit 1 is 2.5-5mm, and length is 20-50cm, and the quantity of main chamber side opening 5 is 2-5, linearly distributes, and side opening diameter is 0.3-1.5mm.Tube material uses shore hardness at the medical embedded level of polyurethane, silica gel or the TPE of 40A～75D macromolecular material, not with tissue adhesion, can realize visually under B ultrasonic or X-ray, and when convenient treatment, location, can be implanted in the whole course for the treatment of human body.
When clinical use, first, according to image check assessment gross tumor volume, major diameter, calculate the quantity that uses particle, and it is sent into push rod, the short tube interval being cut into by demand with implantable plastic tube between particle, after last granule is inserted, with longer plastic tube sealing, in case particle is shifted, comes off.Use Seldinger(Sai Erdingge) puncture method or the seal wire of inserting be in advance via the exchange of side chamber, by conduit placement in the treatment position, sews up fixingly, needs regularly nursing and detect according to treatment, after finishing the course for the treatment of, extracts conduit.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of this utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
