Endoscope probe, endoscope and scanning control method thereof

Abstract

The invention relates to an endoscope probe, an endoscope and a scanning control method thereof. The endoscope probe comprises an optical fiber and a super lens. Wherein the optical fiber comprises a signal input fiber core, a signal output fiber core and a coating layer. The signal input fiber core is used for transmitting an input laser signal; the super lens comprises a light-permeable substrate and a plurality of nano structures arranged on the same surface of the substrate, and the plurality of nano structures are arranged in an array and are attached to the far-end surface of the signal input fiber core, so that an input laser signal is focused on the inner surface of a to-be-detected tissue; the signal output fiber core is used for transmitting the laser signal reflected by the inner surface of the to-be-detected tissue, and the reflected laser signal is subjected to signal processing to obtain an inner surface image of the to-be-detected tissue. According to the technical scheme, due to the fact that the super lens is light, thin, easy to install, low in cost and high in productivity, the structural complexity, the size and the manufacturing cost of the endoscope probe are reduced, and disposable use can be achieved to improve safety.

Description

technical field [0001] The invention relates to the field of endoscopes, in particular to an endoscope probe, an endoscope and a scanning control method thereof. Background technique [0002] Endoscopy may involve accessing and visualizing the interior of a patient's cavity for diagnostic and / or therapeutic purposes. For example, during surgery or examination, an endoscope may be inserted into a patient and instruments may be passed through the endoscope to tissue sites identified for diagnosis and / or treatment. [0003] figure 1 The conventional endoscope shown has an image sensor, an objective lens, a light guide window, an outlet of the clamp channel, a nozzle and an auxiliary water delivery hole, etc., and its structure is complicated, its size is large, and its manufacturing cost is relatively high. [0004] As an important part of the endoscope, the endoscopic probe's structural complexity, size and manufacturing cost will inevitably affect the application of the end...
