Abstract

The invention relates to the technical field of medical treatment, and discloses a large-view-field laparoscope lens, which comprises a laparoscope lens, a first lens mounted at one end of the inner side of the laparoscope lens and fixedly connected with the laparoscope lens; a second lens mounted at one end of the inner side of the laparoscope lens and fixedly connected with the laparoscope lens, and the second lens is located on one side of the first lens; a third lens mounted at one end of the inner side of the laparoscope lens and fixedly connected with the laparoscope lens, and the third lens is located on one side of the second lens; a fourth lens mounted at one end of the inner side of the laparoscope lens and fixedly connected with the laparoscope lens, and the fourth lens is located on one side of the third lens; a fifth lens mounted at one end of the inner side of the laparoscope lens and fixedly connected with the laparoscope lens, the fifth lens is located on one side of the fourth lens. Through combination of the five lenses, the cell resolution is guaranteed while the overall aberration is effectively corrected.

Description

technical field [0001] The present invention involves the field of medical technology, and more specifically, the invention involves a laparoscopic lens and usage method. Background technique [0002] Confocal endoscope, also known as confocal laser endoscope, is derived from the confocal microscope commonly used in laboratories. It applies the principle of confocal endoscope used in traditional laboratory desktops to endoscopic technology. The method is to integrate a confocal laser probe at the end of the endoscopic lens, and use a special fluorescent agent to excite a device that generates a histological image of the human body with a laser. [0003] In actual use, the existing confocal laparoscopes for intra-abdominal tissue imaging have a small imaging field of view while maintaining cell resolution, which in turn increases the difficulty of surgery. Secondly, the internal structure of the existing confocal endoscopes is relatively Complex, not easy to process. Conte...
