Personalized three-dimensional (3D) printing-based brain seed implantation guidance system

Abstract

The invention relates to a 3D printing-based personalized cranial particle implantation guide system, including a head-fixed vacuum pad, particle implantation planning software, a personalized skull perforation template, a personalized particle implantation puncture template, template making and Printing software, 3D printer. The skull perforation template of the present invention is used in conjunction with the particle implantation puncture template, so that the intersection point of each particle implantation needle body is at the perforation of the skull, and the puncture needle passes through the skull smoothly, and the particle implantation needle column of the template can accurately guide the puncture needle. The puncture direction avoids blood vessels and important central nerves, accurately punctures to the lesion, reduces the difficulty of the operation, shortens the operation time, and reduces the risk of the operation.

Description

technical field [0001] The invention relates to the field of medical devices, and in particular provides a 3D printing-based personalized brain particle implantation guide system. Background technique [0002] With the continuous increase of the incidence of tumors and the continuous improvement of medical technology, there are more and more methods of tumor treatment. Due to the small damage, low side effects and remarkable curative effect of radioactive seed implantation, it has been widely used in clinical practice. The traditional freehand puncture technique requires high requirements and depends on the professional quality and operating experience of the doctor. The accuracy of the operation is low and the expected effect cannot be achieved. With the development of medicine, a guide plate for particle implantation has appeared for use in non-cranial parts. Although this method has significantly improved the accuracy of surgery, the location of malignant tumors in the br...

Problems solved by technology

The traditional freehand puncture technique requires high requirements and depends on the professional quality and operating experience of the doctor. The accuracy of the operation is low and the expected effect cannot be achieved.

With the development of medicine, a guide plate for particle implantation has appeared for use in non-cranial parts. Although this method has significantly improved the accuracy of surgery, the location of malignant tumors in the brain is special and belongs to the central nervous system of the human body. Nerves, blood vessels It is rich and covered by the skull, which is different from other parts. It has always been the difficulty of particle implantation. At present, various implant templates cannot complete the brain particle implantation.
