Abstract

The invention discloses a tumor targeted non-destructive low-power laser multi-functional scalpel system and relates to the technical field of medical instruments. The tumor targeted non-destructive low-power laser multi-functional scalpel system comprises a photodynamic therapy system and a multi-scalpel system, wherein the photodynamic therapy system is combined with the multi-scalpel system, and the photodynamic therapy system and the multi-scalpel system are connected with a host machine of the multi-scalpel system through active wires. According to the tumor targeted non-destructive low-power laser multi-functional scalpel system, the microcosmic cancer cell killing function of photodynamic therapy is added to current scalpels; due to the adoption of invisible low-power laser, the visual field of an operation is not influenced; by means of the dual-targeting property of the photodynamic therapy, cancer cells are killed selectively, normal tissue of a patient is not injured, a doctor conducting the operation is not influenced, and perfect combination of macroscopic tumor excision and microscopic tumor cell dissection is achieved for the first time.

Description

Technical field:

[0001] The invention relates to the technical field of medical devices, in particular to a scalpel system, in particular to a tumor-targeting non-destructive weak laser multifunctional scalpel system. Background technique:

[0002] According to the China Health Statistical Yearbook published in 2012, cancer is the leading cause of the top ten causes of death among residents, with a crude death rate of 172.33 / 100,000, much higher than the second-ranked heart disease. The top ten malignant tumor mortality rates in 2004-2005 were lung cancer, liver cancer, gastric cancer, esophageal cancer, colorectal cancer, leukemia, brain tumor, breast cancer, pancreatic cancer, and bone cancer. Except for leukemia, the others were all solid tumors. That is, tumors that are visible to the naked eye. Among them, the total resection rate of liver cancer has been improved in recent years, but it is still less than 30%. Unfortunately, even after resection, the tumor recurrence ...
