Description

OCT detects nasopharynx guide and includes its biopsy device Technical Field The invention relates to the technical field of medical instruments, in particular to an OCT (optical coherence tomography) detection nasopharynx guide and a biopsy device comprising the same. Background The optical interference tomography (Optical Coherence Tomography, OCT) is an optical imaging technique that obtains a two-dimensional or three-dimensional structure of a biological tissue by detecting back-reflected or scattered signals of the incident weak coherent light by different tissues based on the weak coherent light interference principle. The OCT optical scanning probe obtains images through the rotation scanning of the internal optical fiber guide wire, and the axial movement of the probe can scan layer by layer while the optical fiber guide wire rotates, so that richer image information can be obtained. Nasopharyngeal biopsy is a commonly used method for the identification of nasopharyngeal lesions, especially nasopharyngeal malignant tumors, the biopsy histopathological diagnosis of which is a final judgment gold standard. Methods of nasopharyngeal biopsy in the prior art include transoral route nasopharyngeal biopsy and transnasal route nasopharyngeal biopsy. An assistant or a patient presses down the tongue root by using a tongue depressor, the operator holds a direct or indirect nasopharyngoscope left and holds a nasopharynx biopsy forceps right, after a lesion part is peeped, the nasopharynx biopsy forceps enter an oral cavity, enter the nasopharynx cavity from the rear direction of a uvula, and open a front section to clamp a living body for detection, so that the problems that a sample cannot be acquired while observation is carried out and the detection and acquisition efficiency is low are caused.
