Device and method for treating cancer cells and tumors through laser

Abstract

The invention relates to a cancer cell and tumor laser treatment device and method, and the device comprises a catheter, the bottom of the catheter is provided with an opening, the opening is used for positioning a cancer cell or tumor area, and the catheter is also provided with an optical window corresponding to the opening; the first laser directly faces the optical window, and the first laser is used for emitting a first laser beam, so that the first laser beam penetrates through the optical window and irradiates the opening; the vacuum suction device is arranged at the end, away from the opening, of the guide pipe, and the vacuum suction device is used for generating negative pressure at the opening. The invention relates to a device for treating cancer cells and tumors by laser and a treatment method, which are not easy to cause death of normal tissues and cells, and can guide a gas-phase removal substance at an opening, so that the gas-phase removal substance flows out along a conduit, and the cancer cells are effectively prevented from being transferred to other parts due to gas flow.

Description

technical field [0001] The invention relates to the technical field of cancer cell and tumor treatment, in particular to a laser treatment device and treatment method for cancer cell and tumor. Background technique [0002] At present, cancer and tumors are the second leading cause of death in the world. One-sixth of the deaths in the world are caused by cancer. In 2020, it will cause nearly 10 million deaths. It is a disease that has plagued human beings for a long time. [0003] In related technologies, cancer and tumor treatment methods generally include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy, laser therapy, and the like. At present, surgery and laser can quickly remove cancer cells and tumors, but the force during surgery can easily cause cancer cells to transfer to other parts through the blood, and high-power-density laser irradiation can easily cause cancer cells to transfer to other parts due to the flow of ablation gas. parts.
