Tail end puncture mechanism capable of automatically fixing radioactive particle puncture needle

Abstract

The invention discloses a tail end puncture mechanism for automatically fixing a radioactive particle puncture needle, and belongs to the field of medical instruments. The puncture movement mechanism is connected with the bottom plate, and the bottom plate is connected with the puncture needle automatic clamping mechanism, so that the puncture needle can be automatically tightened and loosened; a driven belt wheel is installed at the tail end of a clamping mechanism body in the automatic puncture needle clamping mechanism, the driven belt wheel is connected with a driving belt wheel through a synchronous belt, the driving belt wheel is installed on a rotating motor, the rotating motor is installed on a rotating motor support, the rotating motor support is installed on a bottom plate, and rotation of a puncture needle can be achieved. The inner needle driving mechanism is mounted on the floor, the inner needle driving motor controls the movement of the friction wheel through gear transmission, the friction wheel drives the inner needle to move, the structure can realize the reciprocating motion of the outer needle of the puncture needle at different speeds and the automatic tightening and loosening, and the reciprocating motion of the inner needle at different speeds, and radioactive particles can be accurately and reliably implanted into a focus part; therefore, the purpose of accurate treatment is achieved.

Description

technical field [0001] The invention relates to a terminal puncture mechanism for automatically fixing a radioactive particle puncture needle, belonging to the field of medical instruments. Background technique [0002] Brachytherapy is one of the effective methods for the treatment of cancer. The radioactive seed implantation therapy technology is to implant radioactive seeds into the tumor lesions, and use the radiation continuously emitted by the radioactive particles to kill the cancer cells. This technology is targeted. It has the characteristics of strong, small trauma, quick recovery and no side effects. It has been widely accepted due to its good clinical effect. At present, this treatment method is basically done manually by doctors, which requires high doctors and cannot guarantee the accuracy. In addition, the efficiency of particle implantation is low and the operation time is long. Therefore, there is a need for an automatic puncturing device that can improve ...
