Auxiliary device based on intracranial tumor puncture treatment and preparation method

Abstract

The invention discloses an auxiliary device based on intracranial tumor puncture treatment and a preparation method, and particularly relates to the technical field of medical treatment. The auxiliarydevice comprises a fixing device and a puncture guiding device, wherein the fixing device comprises a lower fixing part and an upper fixing part, a fixing cavity is defined between the opposite surfaces of the lower fixing part and the upper fixing part, a round hole 12 perpendicular to the surface of the upper fixing part and penetrating through the upper fixing part is formed in the upper fixing part, and round holes 5 enabling the upper fixing part to be hollow are formed in the outer side of the round hole 12. According to the invention, a personalized fixing and guiding device is manufactured by utilizing a 3D printing technology to assist in performing the operation in a medical and industrial combined mode, and then the fixing device attached to a CT scanning bed is manufactured according to the CT image of the patient to realize the fixation of the body position, so that the CT scanning body position planned by the dose of the patient is consistent with the intraoperative bodyposition; and besides, a positioning guide plate for intraoperative assistance is manufactured according to a needle passage determined by a dose planning scheme, so that the determinacy of the puncture depth and angle is ensured while intraoperative adjustment is realized, and operation in the planning scheme and intraoperative implementation are unified.

Description

technical field [0001] The invention relates to the field of medical technology, more specifically, the invention relates to an auxiliary device and a preparation method based on intracranial tumor puncture therapy. Background technique [0002] The treatment of intracranial tumors has always been a clinical focus and difficulty. The ultimate goal of treatment is to completely remove or inactivate the tumor while protecting the normal brain tissue and avoiding complications. Some tumors cannot be treated by surgery and external radiotherapy. It can only be treated by implanting radioactive particles into the tumor site through body surface puncture for precise internal radiotherapy. It is necessary for the surgeon to perform puncture and implantation in strict accordance with the preoperative planning system design during the operation, and strive to achieve preoperative and intraoperative planning and dose Only by keeping consistent can the satisfactory curative effect be o...

AI Technical Summary

Problems solved by technology

[0003] Although the preoperative dose planning and intraoperative puncture scheme of radioactive seed implantation for intracranial tumors are very mature, the CT position of the patient in the preoperative dose planning scan is different from that of the patient during the operation, and it cannot be fixed accordingly. In addition, due to the high requirements for the puncture technique of the surgeon, the CT equipment scans during the operation and then guides the puncture, mainly relying on the experience of the operator for blind puncture, which leads to uncertainty in the depth and angle of the puncture. The preoperative planning cannot be fully realized, and due to the particularity of the brain tissue, multiple and re-punctures cannot be performed
