Solution Overview
Problem
Current radioactive source implantation surgeries face challenges such as manual intervention leading to radiation exposure for doctors, and the need to overcome disinfection and biocompatibility issues with implanting radioactive seeds directly into the body.
Innovation Solution
A multi-channel radioactive source implantation device that uses a flexible delivery tube connected to a needle trocar, allowing for multi-channel implantation and reducing the risk of patient scratching. The device includes a first motion platform and connection parts to facilitate relative motion and docking of the wire output channel with flexible delivery tubes, enabling automated seed or seed strand implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual intervention is used in seed implantation surgery, then the surgical process can be controlled, but doctors are exposed to radiation
Solution Approach 1:
The patent replaces manual mechanical intervention with an automated robotic system. The robot performs seed implantation through automated needle positioning and seed delivery mechanisms, eliminating the need for doctors to manually handle radioactive seeds while maintaining precise surgical control through computerized navigation and control systems.
2Reliability
If radioactive seeds are implanted directly into the body, then treatment effectiveness is improved, but disinfection and biocompatibility challenges arise
Solution Approach 1:
The patent extracts the radioactive seeds from direct contact with the implantation device. Instead of implanting seeds directly through the device, the system delivers seeds through a delivery catheter that remains outside the body, allowing the seeds to be deposited at the target site without compromising the sterilization and biocompatibility of the implanted device.
3Stability of the object's composition
If a rigid connection is used between the robot and puncture needle, then structural stability is improved, but the patient may be scratched and the connection structure becomes complex
Solution Approach 1:
The patent replaces the rigid connection between the robot and puncture needle with a flexible delivery tube. This flexible tube maintains the necessary structural connection for stable needle positioning while eliminating the sharp edges and rigid surfaces that could scratch or injure the patient during the surgical procedure.
4Productivity
If multi-channel implantation is implemented, then surgical efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-channel implantation capability through a single integrated delivery system. The device can selectively deliver seeds through multiple channels or pathways using a unified control mechanism and delivery catheter system, achieving enhanced surgical efficiency without proportionally increasing overall device complexity through modular and versatile design.

AI summary
This present invention discloses a multi-channel radioactive source implantation device and its method of use. The device comprises a main control body, a first motion platform, a first connecting portion, a wire output channel, a pushing wire, a wire driving mechanism, and a radioactive source feeding mechanism. The wire driving mechanism connects to the wire output channel. The radioactive source feeding mechanism is used to set radioactive source in the front of the pushing wire. The wire driving mechanism is used to drive the pushing wire to move back and forth along the wire output channel. The wire output channel is a rigid structure or a flexible structure that can be bent. One end of the wire output channel and the first connecting portion are respectively located on the opposite sides of the first motion platform. The first motion platform is used to control the relative motion in space between one end of the wire output channel and the first connection part, so that it makes the wire output channel to dock with one end of connection hole of different flexible delivery tubes, and the seeds or seed strands are pushed out from different connection holes, thereby achieving multi-channel implantation. This invention helps to enhance the implantation precision and efficiency, achieves fully automated operation, and helps to avoid radiation risks and reduce surgical time.
