Title:
MULTI-CHANNEL RADIOACTIVE SOURCE IMPLANTATION SYSTEM WITH NEEDLE-PULLING DRIVING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2024/040999
Kind Code:
A1
Abstract:
The present invention relates to a multi-channel radioactive source implantation system with a needle-pulling driving function, comprising a push rod output channel, a push rod, a push rod driving mechanism, a first connecting part, a first motion platform and a needle-pulling driving mechanism. The push rod pushes a radioactive source arranged in front of the push rod to be output along the push rod output channel; the first connecting part and one end of the push rod output channel are arranged on both sides of the first motion platform, respectively; the needle-pulling driving mechanism and one end of the push rod output channel are arranged in parallel; and the first motion platform drives one end of the push rod output channel and the needle-pulling driving mechanism to have relative motion with respect to the first connecting part. By means of the relative motion between the push rod output channel and the first connecting part, the push rod output channel can be docked with different hole positions to achieve the multi-channel implantation of radioactive particles; and by means of the needle-pulling driving mechanism, a puncture needle can be pulled out automatically, so that the implantation precision and the implantation effect is improved, fully-automatic operation is realized, the radiation risk is avoided, the operative time is shortened, the structure is simple and reasonable, and driving is convenient and rapid.
