Abstract

The invention belongs to the field of medical instruments and particularly relates to a glioma diagnosis and treatment device which comprises a photodynamic irradiation catheter and an implantation catheter mutually matched in use. The photodynamic irradiation catheter comprises an irradiation catheter body, and a photodynamic irradiation optical fiber is arranged in the irradiation catheter body;one end of the photodynamic irradiation optical fiber is positioned on the lower end face of the irradiation catheter body, and the other end of the photodynamic irradiation optical fiber is connected with a photodynamic interface; the irradiation end of the irradiation catheter body is also provided with an imaging component; an illuminating light source is further arranged at the illuminating end of the illuminating catheter body. According to the invention, the split type photodynamic irradiation catheter and the implantation catheter are adopted, the photodynamic irradiation catheter andthe implantation catheter are simple in structure, the device is a microtrauma diagnosis and treatment instrument aiming at tumor recurrence, which can be applied to the head of a patient after gliomaremoval operation for a long time, can be applied repeatedly and minimally invasive, is sensitive, fast and accurate in diagnosis and treatment. The human body implantation part is simple in structure and small in size, can be implanted for a long time, and does not influence the appearance and daily life of the patient.

Description

technical field

[0001] The invention belongs to the field of medical equipment, and more specifically relates to a device for diagnosing and treating glioma. Background technique

[0002] Glioma is the most common primary malignant brain tumor derived from glial cells in the brain and spinal cord. The treatment for glioma is generally surgical resection plus postoperative chemotherapy and radiotherapy. However, gliomas, especially high-grade gliomas, inevitably recur, and the prognosis is extremely poor. Therefore, there is a need for a diagnosis and treatment technique that can be used multiple times after surgery and causes less damage to the patient to treat the recurrence of glioma.

[0003] Photodynamic therapy is an emerging tumor treatment method. Its principle is to inject a specific photosensitizer into the human body. Within a certain time window, the photosensitizer will be specifically enriched in the tumor tissue. At this time, a light source with a specific w...
