Problems solved by technology

However, since it is directly implanted into the human body, and it is a radioactive source, the indications must be strictly controlled. In the prior art, the particle implantation operation depends entirely on the doctor’s clinical experience. Although there is a simple particle implantation template as a guide, if you want to Accurate and regular seed implantation may require doctors with 20 to 30 years of clinical experience. For doctors with only a few years of clinical experience, not only the implantation is inaccurate, but also the implantation of radioactive seeds in the tumor is very uneven. The seeds are implanted into non-tumor cells, so the doctor’s experience in seed implantation needs to be accumulated for a long time, and it is difficult for new doctors to grow quickly, which is not conducive to the development of the industry

Embodiment 1

[0034] Such as figure 1 As shown, a particle implantation device proposed by the present invention includes

[0035] The lower abutment seat 1 for resisting the patient and guiding the puncture needle, the lower abutment seat 1 is arranged on the guide rod 2, and the upper push seat 3 for moving the puncture needle upward is slidably arranged on the guide rod 2, and the upper push seat 3 is also A limit seat 4 for limiting the upward movement distance of the push-up seat 3 is slidably provided, and the limit seat 4 is located above the push-up seat 3 .

[0036]In this implementation, the lower support seat 1 in the particle implantation device is used to hold the patient, and then the doctor holds the guide rod with one hand, and presses the upper push seat 3 and the limit seat 4 with the thumb and index finger of the other hand. There is a certain amount of damping between the rods 2, so it is only necessary to simply control the strength when using it, and use the different...

Embodiment 2

[0038] Such as figure 2 As shown, a particle implantation device proposed by the present invention includes all the structures of Embodiment 1. A second guide rod 29 is arranged on the limit seat 4, and the second guide rod 29 passes through the guide rod 29 on the push-up seat 3. Hole 5. An elastic member 6 is also arranged between the push-up seat 3 and the limit seat 4, and the second guide rod 29 is also provided with an adjustment for adjusting the maximum distance between the limit seat 4 and the push-up seat 3 under the action of the elastic member 6. Nut 7.

[0039] In this embodiment, in addition to guiding and moving the push-up seat 3 and the limit seat 4 on the guide rod 2, a second guide rod 29 is also specially added, so as to better realize the connection between the push-up seat 3 and the limit seat 4. The guide rods 2 remain stationary and move relative to each other. One is relatively stationary and the other moves relatively, thus realizing the quantitati...

Embodiment 3

[0041] A particle implantation device proposed by the present invention includes all the structures in Example 1. A gap 8 is provided on one side of the lower seat 1 and the upper push seat 3, and the gap 8 gradually becomes smaller from the edge to the inside, and the innermost part is Circular hole 9 for passing the puncture needle.

[0042] In this embodiment, the notch 8 is triangular, and the innermost is a circular hole 9. The original designed structure not only ensures the precise movement of the puncture needle in the vertical direction, but also realizes the removal of the puncture needle in the middle process. Use in more situations.

Abstract

The invention belongs to the technical field of particle implantation and provides a particle implantation device. The device comprises a lower abutting seat used for abutting against a patient and guiding a puncture needle. The lower abutting seat is arranged on a guide rod, and an upper push seat used for upwards moving the puncture needle is arranged on the guide rod in a sliding mode, a limiting seat used for limiting the upward-moving distance of the upper push seat is arranged on the upper push seat in a sliding mode, and the limiting seat is located above the upper push seat. A second guide rod is arranged on the limiting seat, and the second guide rod penetrates a guide hole located in the upper push seat. An elastic part is further arranged between the upper push seat and the limiting seat, and an adjusting nut used for adjusting the maximum distance between the limiting seat and the upper push seat under the effect of the elastic part is arranged on the second guide rod. According to the invention, the technical problems of inaccurate and uneven particle implantation in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of particle implantation, and relates to a particle implantation device. Background technique [0002] The full name of seed implantation is "radioactive seed implantation therapy technology", which is a treatment method that implants a radioactive source into the tumor to destroy the tumor. The particle implant therapy technique involves a radioactive source, the core of which is radiating particles. However, since it is directly implanted into the human body, and it is a radioactive source, the indications must be strictly controlled. In the prior art, the particle implantation operation depends entirely on the doctor’s clinical experience. Although there is a simple particle implantation template as a guide, if you want to Accurate and regular seed implantation may require doctors with 20 to 30 years of clinical experience. For doctors with only a few years of clinical experience, not only the implantati...
