Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030]In terms of materials, considering the portability requirements of the structure, most parts are made of aluminum alloy, and other related functional parts are made of alloy steel according to actual use requirements. The overall structure drives the electric cylinder through a closed-loop stepping motor to realize the overall lifting movement. The spatial positioning of the guiding module and the puncture module is completed by four closed-loop stepping motors, and the puncture is completed by two stepping motors, which can fully meet clinical needs. In order to meet the flexibility requirements of the device design, a set of universal wheels and a set of electric push rods are designed at the bottom of the device. Through the cooperation between the two, the CT bed of the mechanism can be placed in all directions, so as to achieve all-round The installation pos...

Abstract

The invention discloses a floor type automatic puncture device for tumor radioactive seed implantation treatment. The main functions of the floor type automatic puncture device comprises the positioning of a puncture needle guide module and the automatic puncturing of a puncture module. The floor type automatic puncture device has the advantages that tumor puncture of different parts can be achieved by replacing different guide devices, the guide module and the puncture module implant seeds into the corresponding part in a coordinated manner to achieve precise implantation, and accordingly precise radiotherapy is achieved; when the floor type automatic puncture device is used, the device is placed beside a CT bed, the guide module precisely position the guide device to the treatment part,and the puncture module implant a puncture needle into a human body to achieve precise radioactive seed implantation; the floor type automatic puncture device is stable in structure, precise, efficient and capable of being used as the reference of radiotherapy seed implantation auxiliary equipment; the positioning of the guide module and the puncture module adopts rotation freedom degree, workingspace is increased, the extending part can be folded and retracted after work, space occupation is reduced greatly, and moving is facilitated; key freedom degrees are provided with limit sensors to guarantee moving safety.

Description

technical field [0001] The patent of the present invention relates to the field of medical equipment, which belongs to the cutting-edge discipline intersecting the fields of machinery and medical radiotherapy, and relates to the equipment and technology used in brachytherapy radioactive particles. Specifically, it is a floor-standing automatic puncture device for radioactive particle implantation therapy of tumors. Background technique [0002] Radiation therapy is one of the main methods for treating tumors at present, and it is divided into external radiation therapy and brachytherapy. External radiation is to focus the rays outside the human body through X-ray therapy machines, etc., and irradiate the surface of the body or tumor parts in the body for a short time to kill tumor cells. Brachytherapy is to permanently or temporarily introduce high-dose-rate radioactive source particles into the cancerous part of the tumor through external devices, so as to kill tumor cells...
