Abstract

During the manual implantation process of radioactive particles, the technical skill of doctors is strictly required. In addition, the implantation workload of the particles is large, the surgical time is long, and the particle implantation precision also can be affected. In order to solve the problem, the invention relates to an electric particle implantation device for short-distance radioactive therapy. The electric particle implantation device comprises a soleplate, an outer needle drive module, an inner needle drive module, an inner needle, an outer needle and a radioactive particle supply module, and is characterized in that the soleplate is fixedly connected with an outer needle drive motor and an inner needle drive motor, an outer needle clamping sleeve is fixedly connected with the outer needle, the inner needle drive module is connected with the inner needle by virtue of a friction pair, the inner needle is a solid needle, the outer needle is a hollow needle, and the inner needle slides in the outer needle. The electric particle implantation device can be used as an end execution mechanism of a mechanical hand to automatically implant particles, the high-precision radioactive particle implantation surgical operation can be realized by adopting image navigation, and the electric particle implantation device also can be used as an electric handheld radioactive therapy particle implantation device and is simple in structure.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an electrokinetic particle implantation device for brachytherapy. Background technique [0002] Proximate radioactive seed implantation provides a new effective way for the treatment of malignant tumors. especially 125 The application of I particles has been widely used because of its good therapeutic effect, uniform dose distribution in target tissue, and little damage to normal tissue. At present, puncture implantation under the guidance of ultrasound, CT, and MRI is widely used, and doctors use manual implantation during the implantation process. During the manual implantation process, the doctor's technical level is strictly required, and the quality of the operation is unstable. In addition, the workload of particle implantation is heavy and the operation time is long, which will also affect the accuracy of particle implantation. Contents of the invention [0003] The pu...
