Embodiment approach

[0039] As the first embodiment of the present invention, the 30° viewing angle lens structure includes a spacer ring 1-2-24, a first lens (1-2-20), a light The axis deflection member (1-2-12), the second lens (1-2-21) and the lens group (1-2-23), the difference between the light incident from the first lens and the light emitted from the optical axis deflection member The included angle is 30 degrees, and the light emitted by the optical axis deflecting member is parallel to the central axis of the outer tube, and after being emitted by the second lens (1-2-21) and the lens group (1-2-23), it is in the sleeve tube on the corresponding side Long-distance transmission to the rear lens; the optical axis deflecting member can be a prism.

[0040] As the second embodiment of the present invention. The 0° viewing angle lens structure includes a plurality of lenses arranged in sequence from the object side to the image side, and the centers of the plurality of lenses are on a straig...

Abstract

The invention discloses a three-dimensional endoscope device for a minimally invasive neurosurgery robot. The three-dimensional endoscope device comprises a three-dimensional endoscope body inserted into a patient body cavity such as the peritoneal cavity, a two-way video crew located out of the patient body and clamped by an operating arm of the minimally invasive neurosurgery robot, a camera processing unit for collecting and processing two-way images and an adjustable illumination cold light source. According to the three-dimensional endoscope device, the adjustable illumination cold light source provides two illumination channels through a Y-shaped optical fiber, the quantity of the cold light source in an operation is reduced, and meanwhile the sufficient even illuminating degree is provided for a three-dimensional endoscope illuminating system. By means of the three-dimensional endoscope device, rapid disassembling and reliable connection of a three-dimensional endoscope and the two-way video crew are achieved, and the three-dimensional endoscope device has the advantages of being easy to sterilize, convenient and fast in starting connecting, safe in operating and the like.

Description

technical field [0001] The invention relates to the field of stereoscopic endoscope vision, and is used in conjunction with a minimally invasive surgical robot system, in particular to the overall structure of a stereoscopic endoscope device. Background technique [0002] At present, minimally invasive surgery represented by laparoscopy has been applied in many surgical fields, which is an important medical science progress in the 20th century. Under laparoscopic surgery, doctors insert long and thin surgical tools and endoscopes into the body through tiny incisions on the patient's body surface for surgical operations. Compared with open surgery, laparoscopic surgery has the advantages of less bleeding, smaller surgical incisions, and a lower probability of infection, thereby reducing the patient's recovery time. Then, in traditional laparoscopic surgery, doctors can only obtain flat visual feedback information through 2D endoscope, and lose the three-dimensional perceptio...
