Abstract
The utility model discloses a shell structure of a radioactive sealed seed source. At least one of annular grooves on the surface of a shell is discontinuous; and another section of groove crossed with the discontinuous annular groove is formed at each section of the discontinuous annular groove to form a fork-shaped groove. Through the fork-shaped grooves, the shell is firmly and reliably engaged with human tissue, the radioactive sealed seed source can be stably fixed in target tissue and is well prevented from wandering, non-target tissue is prevented from being radiated unnecessarily, and the safety and practicability of the radioactive sealed seed source implanted into a body are greatly improved.
Description
Technical field
This utility model relates to the shell mechanism of the radioactive seed source, particularly a kind of radioactive seed source of oncotherapy use.
Background technology
Treatment is that radionuclide is sealed in metal or the composite with radioactive sealed seed source, implants as radioactive source according to the precalculated position, and tumor is carried out directed radiotherapy, kill cancer cell, thus reach the purpose of treating tumor.After implanting, radioactive sealed seed source is fixing not migration in the precalculated position, and is most important to reaching ideal therapeutic effect.Yet present sealed seed source shell on the market is mainly the cylindrical of smooth in appearance, and behind implanting tissue, the easy migration in seed source causes non-target tissue to receive unnecessary radiation, even causes the necrosis of indivedual tissues or blood vessel in its hetero-organization or blood vessel.Radioactive seed source is also arranged; Through successive annular groove is set in case surface; To strengthen the gmatjpdumamics of itself and tissue,, still dislike not enough though this shell mechanism increases the anti-migration performance in seed source; The migration phenomenon still happens occasionally, and fails to solve very effectively sealed seed source steadiness in vivo.
Summary of the invention
This utility model is intended to provide the shell mechanism in the better radioactive sealed seed source of a kind of anti-migration performance, with the more effective solution sealed seed source problem of migration in vivo, improves the safety and the practicality in radioactive sealed seed source.
The shell mechanism in the described radioactive sealed seed of this utility model source, the surface of its shell is provided with a plurality of annular grooves simultaneously, and having an annular groove in the said annular groove at least is the annular groove of interrupted shape.
The shell mechanism of the described radioactive seed source of this utility model; Because case surface is provided with the annular groove of interrupted shape; Form a plurality of occlusal surfaces between the annular groove ability of interrupted shape and the tissue, radioactive sealed seed source stably is fixed in the target tissue, better prevent the migration of radioactive seed source; Avoid non-target tissue is caused unnecessary radiation, increased safety and practicality that radioactive sealed seed source implants greatly.
The annular groove of case surface setting can be the horizontal groove of level, also can be the oblique groove of inclination, can also have horizontal groove and oblique groove simultaneously.Through the combination of horizontal groove and oblique groove, the fastness of the shell in increase radioactive sealed seed source that can be further and the interlock of tissue further improves anti-migration performance.
Said oblique groove can have one, also can have a plurality ofly, and wherein at least one is the oblique groove of interrupted shape.Oblique groove through interrupted shape can be further increase shell and the occlusal surface between the tissue, increase the fastness of shell and tissue interlock, thereby better improve anti-migration performance, make the use of radioactive sealed seed source safer.
The best angle of inclination of a plurality of oblique grooves of case surface has nothing in common with each other; Oblique groove through differing tilt angles; The gmatjpdumamics of different directions can be provided, thereby increase the interlock fastness of shell and tissue once more, improve the anti-migration performance in radioactive sealed seed source once more.

The specific embodiment
Embodiment 1
The shell mechanism in a kind of radioactive sealed seed source, like Fig. 1, the surface of shell 1 is provided with a plurality of annular grooves, and said annular groove can be the horizontal groove of level, and wherein the annular horizontal groove of part is continuous shape 2, and the part annular groove is interrupted shape 3; For increasing the occlusal surface between shell and tissue, increase the fastness of interlock, improve anti-migration performance, said horizontal groove can all be interrupted shape also.
Embodiment 2
The shell mechanism in a kind of radioactive sealed seed source; Like Fig. 2; The surface of shell 1 is provided with a plurality of annular grooves, the oblique groove of said annular groove for tilting, and each oblique groove angle of inclination is identical, parallel; Wherein the annular oblique groove of part is continuous shape oblique groove 4, and the part annular groove is interrupted shape oblique groove 5.All oblique groove is interrupted shape oblique groove 5; For further increasing the fastness of interlock between shell and tissue, improve anti-migration performance, a plurality of oblique grooves 3 of case surface can be the oblique groove 3 that incline direction has nothing in common with each other, like Fig. 4.Groove through different directions is provided with organize interlock, its can from different direction limit shells with organize between motion, better avoid the migration in radioactive sealed seed source.
Embodiment 3
The shell mechanism in a kind of radioactive sealed seed source; Like Fig. 3; The surface of shell 1 is provided with a plurality of annular grooves, and said annular groove has the horizontal groove of level and the oblique groove of inclination simultaneously, and horizontal groove part is the horizontal groove 2 of continuous shape; Part is the horizontal groove 3 of interrupted shape, or horizontal groove all is the horizontal groove 3 of interrupted shape.Oblique groove partly is the oblique groove 4 of continuous shape, and part is the oblique groove 5 of interrupted shape, perhaps all is the oblique groove 5 of interrupted shape; Carry out interlock through oblique groove and horizontal groove and tissue are set simultaneously, it can better increase the fastness of interlock between shell and tissue, thereby better improves anti-migration performance, and it is safer that radioactive sealed seed source is used; Above-mentioned oblique groove preferably can have nothing in common with each other by incline direction, so that the more firmly interlock between shell and tissue, the migration of avoiding the seed source further to be provided.
