Abstract
The utility model provides an can absorb fixed cover of radioactive particle, it includes fixed cover main part, and fixed cover main part sets up for the hollow structure who link up from top to bottom, and the shape of fixed cover main part and the shape, the size phase-match of size and particle, fixed cover main part outer wall are equipped with outwards upwards protruding fixed cover main part outer wall of barb still are equipped with and supply the barb to return big or small assorted hole, and the barb is placed the in-process at the puncture needle and is met during great resistance retractable to the hole, puts and can expand after in organizing. The utility model has the characteristics of simple structure, can absorb the radioactive particle and not shift, use safelyr etc.
Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of absorbable radioactive particle fixing sleeves.
Background technique
(radiation radius the is 1cm) implantation of radioactivity I125 particle is as a kind of current treatment side of novel malignant tumour
Formula has many advantages, such as.But had a problem that in clinical practice operation, that is, be implanted into the fixation of particle.Due to current iodine
The implantation of 125 particles is by hollow puncture pin puncture to the periphery of corresponding malignant tumour, then by hollow in puncture needle
Radioactive particle is pushed into corresponding site by pipeline.And since I125 particle surface is smooth, it is punctured group in addition and is woven in puncture needle
There are a tissue recoil power after withdrawing from an organization, and just there is I125 particle is squeezed out tissue along puncture channel or makes particle
The possibility of displacement, and such phenomenon repeatedly occurs in clinical practice operating process.If particle displacement, then therapeutic effect will
It has a greatly reduced quality, if deviate from from puncturing tissue, it will be most likely resulted in as a radioactive substance and radiate periphery
Histocyte there are the possibility of canceration.
Therefore, the present inventor devises a kind of fixed nested structure of the absorbable radioactive particle that can overcome drawbacks described above,
It can be very good to solve the above problems.
Utility model content
The purpose of this utility model is that not changing on the structure basis of implantable particle, provide a kind of for outside particle
The barbed fixed nested structure absorbed by the body in a very thin surface.
The technical solution of the utility model is achieved in that
A kind of absorbable radioactive particle fixing sleeve comprising fixing sleeve main body, fixing sleeve main body are sky up and down
Core structure setting, shape and the size and the shape of particle, size of fixing sleeve main body match, fixing sleeve body outer wall equipped with to
Outer upward hangnail, fixing sleeve body outer wall are additionally provided with the hole matched with hangnail size shape, and hangnail is through puncturing
Larger resistance is met in needle placement process to be bounced back in hole, put as can spread apart after in tissue.
Further, the length of fixing sleeve main body is less than the length of particle.
Further, hemostatic layer and/or anti-inflammatory layer are provided in fixing sleeve main body.
Compared with the relevant technologies, this absorbable radioactive particle fixing sleeve have the characteristics that structure simply, using safer.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure, fixing sleeve main body -1, radioactivity I125 particle -2, hangnail -3, hole -4.
Specific embodiment
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Embodiment
Figure, absorbable radioactive particle fixing sleeve according to the present utility model, including fixing sleeve main body 1 are please referred to, it is fixed
Main body is covered by that can be made by human body absorbable material, when making fixing sleeve main body, the drug of antiinflammation has been added and/or has risen
The drug of anastalsis, fixing sleeve main body are hollow cylinder structure up and down, the shape of fixing sleeve main body and size with put
Shape, the size of penetrating property I125 particle 2 match, and fixing sleeve body outer wall is equipped with hangnail 3 upward outward, fixing sleeve
Body outer wall is additionally provided with the hole 4 to match for hangnail retraction size, and hangnail meets larger resistance in through puncture needle placement process
Power can bounce back in hole, put as can spread apart after in tissue.
Concrete operating principle are as follows: the radioactivity I125 grain of the outer wall belt fixing sleeve of upward hangnail outward will be provided with
Son is packed into magazine by implantation instrument implantation tumour tissue, and the present embodiment is can absorb in the production of radioactive particle fixing sleeve, fixed
Drug or material such as hemostasis, anti-inflammatory and other effects can be added in cover material, after by the corresponding tumor tissues of seeds implanted, due to falling
The presence of thorn, particle no longer will shift even to deviate from due to the pressure of tissue recoil, so temporary fixed function is played,
After a couple of days, be punctured tissue site of puncture can be formed scab, regeneration and so that particle is permanently secured to corresponding positions
It sets, and the cover of particle surface is then absorbed by the body after a couple of days or several weeks, and restore the surface of particle otherwise smooth, to reduce
To tissue stimulation.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other relevant technical fields, are also included in the patent protection scope of the utility model.
