Description

Technical Field

[0001] This utility model relates to the field of endoscopy, specifically to an endoscopic imaging device. Background Technology

[0002] Endoscopes are multidisciplinary tools used to explore deep within curved tubes, observe areas that cannot be directly seen, observe the internal structure and state of sealed cavities, and perform remote observation and manipulation. Endoscopes are widely used in the medical industry, and are categorized into non-invasive and invasive types. Non-invasive endoscopes are inserted directly to examine cavities that communicate with the outside world, such as the digestive, respiratory, and urinary tracts. Invasive endoscopes are inserted through incisions to examine closed body cavities, such as the thoracic cavity, abdominal cavity, and joint cavities. With the development of neuroendoscopic technology, transcranial endoscopy is increasingly widely used in clinical practice, especially in the deep intracranial and skull base areas. However, unlike transnasal skull base endoscopy, transcranial endoscopy often requires traversing nerves and / or blood vessels. Once the endoscope is fixed by the support arm during the procedure, the area behind the lens becomes a "blind spot," and the constant movement of instruments in and out of the surgical area during the operation can easily cause accidental damage to nerves, blood vessels, and important structures behind the lens.

[0003] Therefore, an endoscopic camera device is needed to eliminate blind spots in the surgical field and avoid accidental damage to related tissues by surgical instruments. Utility Model Content

[0037] The front periphery of the seat 21 is provided with magnetic material;

[0038] The auxiliary camera 22 is located inside the base 21. The auxiliary camera 22 is a CCD camera. The fact that it is located inside the base 21 can reduce the overall size of the auxiliary camera device 2.

[0039] The lighting elements 23 are arranged in a ring around the auxiliary camera 22 to provide illumination for the auxiliary camera 22;

[0040] The auxiliary camera 22 and the lighting element 23 are powered by a battery, which is located inside the base 21;

[0041] In some embodiments of this utility model, the images captured by the auxiliary camera 22 are transmitted wirelessly and displayed on the external display device 4. The external display device 4 can display the image information captured by the auxiliary camera 22 and the main lens 11 in a synchronous, split-screen or picture-in-picture manner.

[0042] The bevel gear 24 is fixedly located on the inner front end of the seat 21;

[0043] In some embodiments of this utility model, such as Figure 2-3 As shown, the rotating device 3 includes a fixed base 31, a micro motor 32, and a bevel gear 33;

The endoscope tube 1 is then inserted into the area where the patient needs to undergo surgery. The surgical site is observed through the main lens 11, while the blind spot behind the main lens 11 and the image of the entry route of the endoscope tube 1 are observed through the auxiliary camera 22 and the illumination element 23 of the auxiliary camera device 2. The images captured by the main lens 11 and the auxiliary camera 22 are synchronized and split-screen. The auxiliary camera 22 can be displayed on an external display device 4 in a picture-in-picture manner without affecting each other. When the shooting angle of the auxiliary camera 22 is obstructed or there is a certain blind spot, the micro motor 32 of the rotating device 3 can be controlled to rotate forward and backward by the control handle of the endoscope. Through the meshing of bevel gear 1 24 and bevel gear 2 33, the seat 21 is driven to rotate around the endoscope tube 1 as the axis.
