Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a medical endoscope and medical examination system. Background Technology

[0002] An endoscope is a specialized medical instrument that can be used to examine or treat internal diseases through natural body cavities or surgical incisions. With the development of microelectronics technology, electronic endoscopes are being used more and more widely in medicine.

[0003] Current neurosurgical endoscopes are rigid. Taking the widely used STORZ endoscope as an example, its main structure includes a front-mounted optical system and a rear-mounted processing system. The front-mounted optical system is a lens end approximately 250mm long, including the objective lens system, the fiber optic light source system, and the endoscope tube. The processing system includes an image sensor, processor, cold light source, and controller, and also integrates a handle and external device connectors. The endoscope tube consists of an endoscope tube and an outer endoscope tube. Both the endoscope tube and the outer endoscope tube are made of rigid materials. This results in the STORZ endoscope having a large and heavy overall structure, numerous and complex external devices, and a relatively high price.

[0004] Endoscopes with rigid endoscope structures cannot be adjusted at will in terms of lens angle and endoscope tube, resulting in poor freedom of observation angle and range. There are still blind spots in the surgical field. When using them, it is often necessary to repeatedly change different models of endoscopes (such as 0°, 30°, 70°, etc.) to achieve the surgical purpose. They cannot be seamlessly connected with surgical microscopes, and one must be removed before another can be used.

[0005] In addition, existing endoscopes are heavy and cumbersome to use. They are difficult to control and fix when performing deep and delicate operations by hand. Doctors need assistants to help hold the endoscope during surgery, which can easily lead to medical risks due to surgical errors. Doctors have a high technical threshold for using them and a long learning period. They are also complex in structure, have many external devices, and take up a lot of space in the operating room. Utility Model Content

[0006] This invention primarily addresses the technical problems of existing endoscopes with rigid endoscope structures, such as the inability to freely adjust the lens angle and endoscope tube, resulting in poor freedom of observation angle and range, heavy endoscope weight, and difficulty in controlling the endoscope during deep and delicate operations.
