Abstract

The invention discloses an OCT (optical coherence tomography) laparoscope structure which comprises a laparoscope body (11), a probe (1), a laparoscope hard rod (3), an OCT light source device (4) anda laparoscope video recording and zooming device (5). The OCT laparoscope structure has the advantages that laparoscope devices and OCT devices are combined with one another, accordingly, minimal invasion and real-time diagnosis can be tightly combined with each other, tissue specimens do not need to be incised to be operated in an in-vitro manner, and malignant tumor can be quickly noninvasivelydiagnosed in an in-vivo manner in real time; the OCT laparoscope structure has an important application value and a broad development prospect in the aspect of noninvasive detection in the fields ofmaterial science, biomedical science and the like; optical signals of normal tissues and focus can be compared to one another by the aid of the OCT light source device, and accordingly quick image bases can be provided for doctors when incisal edges of tumor are judged during surgical operation or can be provided for clinical research.

Description

technical field [0001] The present invention relates to the field of medical equipment, and more specifically, relates to an OCT laparoscope structure. Background technique [0002] Malignant tumors are currently the leading cause of human death. Laparoscopy has been widely used in surgical operations, especially in the radical resection of intra-abdominal tumors, which has the advantages of minimal invasiveness and better visual observation. When laparoscopic surgery is applied to the resection of intra-abdominal malignant tumors, the judgment of the tissue or margin requires the tissue to be resected and sent for rapid pathological examination, often requiring several hours of waiting. OCT technology has been applied to the diagnosis of malignant tumors, which has the advantages of real-time and rapidity. The current OCT device also needs to excise the tissue sample and take it out of the body for operation, which limits its application. Contents of the invention [0...
