RADIOACTIVE SOURCE IMPLANTATION SYSTEM WITH CORE EXTRACTION MECHANISM AND USE THEREOF

WIPO Patent Application WO/2023/165491

A1

Disclosed are a radioactive source implantation system with a core extraction mechanism and use thereof. A push rod driver mechanism is arranged on a body of the system, and is in communication with a push rod output channel. A core extraction mechanism is arranged on one side of a front end of the push rod output channel. The push rod output channel is in communication with a delivery catheter via a channel switching mechanism. The front end of the delivery catheter is connected with a puncture needle or a quick connector configured for connecting a puncture needle. The core extraction mechanism can be aligned to a tail end of a needle core in the delivery catheter and extract the needle core, such that the needle core is extracted from the delivery catheter, thus leaving a hollow implantation channel. A radioactive source supplier part is configured to provide a radioactive source at a front end of a push rod. The push rod driver mechanism actuates the push rod to move forward and push the radioactive source into an organism tissue along the push rod output channel, the delivery catheter, and the puncture needle inserted into the organism tissue. The present invention can reduce the operation duration, achieve automatic operation, and improve the implantation precision and the implantation effect.
