Electronic arthroscope with adjustable imaging angle

Abstract

The invention provides an electronic arthroscope with an adjustable imaging angle. The electronic arthroscope comprises an endoscope image control box, an image monitor and an endoscopic module, the endoscopic module is in data transmission with the endoscope image control box, and the endoscope image control box is in data transmission with the image monitor; image data acquired by the endoscopic module is processed by the endoscope image control box and then is visually displayed through the image monitor; the endoscopic module comprises a lens assembly, a lens barrel and an adjusting assembly. The imaging angle can be conveniently adjusted, multi-angle observation of the focus position can be achieved, and the problem that a traditional arthroscope is single in visual angle is solved. Compared with a traditional arthroscope, the arthroscope has the advantages that the cost is greatly reduced, the arthroscope can serve as a disposable consumable, disinfection is not needed, the risk of infection caused by incomplete disinfection of the traditional arthroscope is avoided, disinfection and sterilization are not needed before each operation, and the operation preparation time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to an electronic arthroscope with an adjustable imaging angle. Background technique [0002] An endoscope is a front end equipped with an imaging device that enters the human body through the natural orifice of the human body or through a small incision made by surgery. When in use, the endoscope is introduced into the pre-examined organ, which can directly peek at the image of the relevant lesion site, which can help the doctor to check the situation in the cavity more comprehensively, and perform the operation under the circumstance, which greatly improves the safety of the operation. [0003] Arthroscope is a kind of medical endoscope. It is a rod-shaped optical instrument used to observe the internal structure of joints. It is an endoscope used to diagnose and treat joint diseases. Traditional endoscopes are mostly rigid fiber imaging endoscopes. However, some problems in th...

AI Technical Summary

Problems solved by technology

[0004] 1) The inclination angle of the objective lens at the front end of the existing arthroscope is a fixed angle, the field of view is small, and there will be blind spots that cannot be observed during surgery. In order to obtain a larger field of view, multiple joints with different inclination angles are often used in surgery Mirrors are used alternately to observe in the patient's joints, which reduces the efficiency of the operation site, causes great inconvenience to the doctor's operation, and increases the operation cost;

[0005] 2) Most of the existing arthroscopes are reusable. Although most of the current arthroscopes can meet the requirements of repeated cleaning and sterilization, it takes a long time and a waste of manpower to clean and disinfect the arthroscope after each operation, and The cost of disinfection equipment is high, repeated disinfection will also shorten the service life of the arthroscope, and it is easy to damage the image transmission system of the arthroscope, which has a great impact on the imaging effect;

[0006] 3) The existing arthroscopy is mainly based on optical mirrors, and the resolution of existing fiber optic imaging is low;

[0007] 4) The optical mirror itself does not have a light source, and it needs to be connected with an optical cable to display the picture on the display;

[0008] 5) Most of the eyepieces and objectives of existing arthroscopes are precision optical parts, which are costly and easy to damage
