AI Technical Summary

Problems solved by technology

However, residual tumor after surgery is the main cause of recurrence and poor prognosis
Traditional tumor localization technology generally has many shortcomings such as inaccurate positioning, long positioning time, invasive, complicated operation, high price, and toxic and side effects of contrast agents on the body.

Abstract

The invention provides a confirming device for glioma boundaries. The confirming device for glioma boundaries comprises a carrying part and a Raman spectrum detecting part; the carrying part comprisesan objective table, a sealing cover and an air bag; the objective table is of spherical shape; a feeding port is formed on the top of the spherical shaped objective table; the sealing cover is arranged on the objective table and is used for sealing the feeding port; the air bag is arranged in the objective table; an aerating port of the air bag is formed on the outer surface of the objective table; the Raman spectrum detecting part comprises a laser transmitter, a dichroscope, a confocal microscope, an optical filter, a detector and a display. The confirming device for glioma boundaries is capable of quickly, accurately and noninvasively confirming the boundaries of glioma infiltrating tissues and non-glioma infiltrating tissues.

Description

technical field [0001] The invention belongs to the medical field, and more specifically relates to a device for determining the boundary of a glioma. Background technique [0002] Among brain tumors, glioma is the most malignant tumor, which has the biological characteristics of invasive growth, and it is difficult to completely remove it by surgery, but the degree of postoperative residual tumor burden directly affects the prognosis. Existing neurosurgery techniques for identifying glioma boundaries still have some drawbacks. For example, intraoperative fluorescence imaging requires the support of a more expensive fluorescent microscope. At the same time, the blood-brain barrier of low-grade gliomas is not fully opened, so the intraoperative imaging effect is not obvious; intraoperative color Doppler ultrasound imaging only shows the outline of the tumor, which is somewhat different from the real situation. Intraoperative nuclear magnetic imaging requires expensive intrao...
