Abstract

The invention relates to the technical field of medical apparatuses and instruments and discloses a surgical imaging device based on a polarizing extinction principle. By configuring polarizers in an imaging assembly and an illumination assembly of the surgical imaging device, reflected light on the surfaces of the tissues in orifices and non-orifice organs can be filtered out by utilizing the polarizing extinction principle, accordingly the influence of the reflected light on the imaging quality can be reduced, high-definition images without surface reflected light are obtained, thus tissue information under the surfaces of the tissues is convenient and close to observe, and the accuracy of operations in the internal medicine department is guaranteed. In addition, by orthogonally arranging the polarization directions of two polarizers, the surface reflected light can be eliminated to the most degree, and the clearest tissue surface images of the orifices and the non-orifice organs are obtained. By arranging the polarization directions of the two polarizers in parallel, images with surface reflected light can be obtained without elimination of the surface reflected light, and accordingly flexible section can be performed according to the clinic application demand.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a surgical imaging device based on the principle of polarization extinction. Background technique [0002] In the course of medical surgery, since the operation area is located inside the human body, an endoscope, laparoscope, etc. are indispensable to collect images inside the human body. However, the imaging device of the existing endoscopic / laparoscopic technology has the following two defects: (1) it cannot avoid the reflected light on the surface of the human cavity or non-cavity, and these reflected light will affect the imaging quality, and then cannot be clearly observed The tissue information below the tissue surface affects the accurate performance of medical surgery; (2) It is impossible to obtain the image of the intracavity or non-cavity without surface reflection light (for clearly observing the tissue information below the tissue surface), and it is also po...
