Background
In local treatment of malignant tumor, radioactive seed implantation therapy is widely used, and in order to implant the seeds into the body to form effective radiotherapy dose, the needle sleeve of the existing seed implantation puncture needle is hollow, and the tail part and the tip part of the needle sleeve are both open. The doctor inserts traditional pjncture needle in the tumour deep, pushes away the particle from needle cover afterbody, pushes away from the point portion, reaches on the position that the doctor planned, then pulls out the mode of needle many times through the segmentation (for example pull out 1 centimetre at every turn just push away 1 particle from the needle cover) implants the particle in the tumour and forms effectual radiotherapy dose, has following not enough during its use:
1. the particles are pushed in from the tail part and pushed out from the tip part, and only one straight line can be formed.
2. Because the tumor can only be arranged in a straight line, a plurality of puncture needles are required to be penetrated if the tumor is slightly large, and the injury to the human body is large.
3. When a plurality of puncture needles are used for treatment, the parallel between the needles is difficult to achieve in the puncture process, so when the particles are implanted, the distance difference between the particles is large, and the radiation dose formed by the particles can generate high-dose and low-dose areas, which is not beneficial to treatment.
4. When a plurality of puncture needles are used for treatment, the directions of the puncture needles need to be adjusted for many times, the treatment process is long in time consumption, and the injury to a human body is large.
In view of this, we propose a medical particle implantation needle.

The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Referring to fig. 1-3, the present invention provides a technical solution:
a medical particle implantation puncture needle comprises a needle sleeve 1 and a needle core 2, wherein the needle sleeve 1 comprises a needle sleeve tail part 101, a needle sleeve body part 102 is arranged on one side of the needle sleeve tail part 101, and a needle sleeve side hole 103 is formed in one side, far away from the needle sleeve tail part 101, of the needle sleeve body part 102.
It is worth further elucidating that,
the stylet 2 comprises a stylet cap 201, and a stylet body 202 is arranged below the stylet cap 201;
the tip of one side of the needle sleeve 1 far away from the tail part 101 of the needle sleeve is in a closed state;
the needle hub tail 101 is threaded.
It is worth further explaining that, by utilizing the characteristic that the tip of the needle sleeve 1 is closed and the side surface is provided with a hole, particles leave the needle sleeve 1 and enter a human body, and are not in the same straight line with the needle sleeve 1. The particle distribution can form a three-dimensional structure by using the puncture needle, and the particle can be implanted by rotating the puncture needle, and different three-dimensional shapes can be formed according to the requirements of doctors, instead of the traditional puncture needle which only can form a straight line.
It should be further noted that the needle hub tail 101 is threaded to be screwed to the particle reservoir, the needle hub 202 is a hollow tube with a diameter slightly larger than the diameter of the therapeutic particle (the specific value is determined according to the size of the particle used), the needle hub side hole 103 is located near the needle hub tip and has a diameter slightly larger than the diameter of the therapeutic particle (the specific value is determined according to the size of the particle used), and when the particle is implanted, the particle reservoir is screwed to the needle hub tail 101 by aligning the threads. When particles are pushed into the needle sleeve 1 from the reservoir, they will exit from the needle sleeve side hole 103 and enter the tumor of the human body.
In this embodiment, the hub tail 101 fits the hub cap 201.
In this embodiment, the length of the needle sleeve 1 is the same as that of the needle core 2.
In this embodiment, the surface of the needle sleeve 1 is provided with scales.
It is worth further explaining that the scale marks are arranged every 1 cm from the tip part to the tail part, and the scales at the positions of 5 th, 10 th and 15 th cm are thickened, so that the length of the puncture needle entering a human body can be conveniently recorded.
In this embodiment, the spike cap portion 201 is a cylinder.
The utility model discloses when using, insert needle cover portion 102 with nook closing body 202 completely earlier, nook closing body portion 201 arrives needle cover afterbody 101, insert the puncture needle inside human body up to the tumour, extract nook closing 2, pass through the spiral with the particle storage and fix at needle cover afterbody 101, push needle cover portion 102 with the particle push rod (its shape is unanimous with the nook closing body, but its length is the length of nook closing body and particle storage's length) to the particle from the particle storage, continue to push in until pushing the particle into the tumour from needle cover side opening 103, extract human 1 centimetre back to the pjncture needle, reuse particle push rod pushes another particle into the tumour, preparation above the repetition is up to reaching doctor's treatment requirement. In addition to the method of directly pulling out the puncture needle, the puncture needle can be rotated; also includes pulling a point, turning a point, such a method to arrange the position of the particles in the tumor to meet the treatment requirements of the doctor.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
