Description

Technical Field

[0001] The invention belongs to the technical field of electronic endoscopes, and in particular relates to an integrated endoscope light guide connector and a light guide connector locking device. Background Art

[0002] Electronic endoscope is a widely used medical device. It can be directly inserted into the human body cavity and organ cavity for direct observation, diagnosis and treatment. It is a medical electronic optical instrument that integrates optical, mechanical, electrical and other high-precision and cutting-edge technologies. At present, a micro CMOS sensor is generally used to image the cavity object to be observed on the CMOS through a tiny objective optical system, and then the received image signal is transmitted to the image processing system, and finally the processed image is output on the monitor for the doctor to observe and diagnose.

[0003] In the medical field, an endoscope needs to enter the human body to illuminate the tissue, and then judge the tissue pathology based on the feedback image. In the prior art, the light energy of the cold light source is generally transmitted to the endoscope mirror through the light guide connector inside the endoscope, and then transmitted to the tip to illuminate the part that needs to be observed. However, the fixing device of the light guide connector in the prior art is a ferrule structure, which has the risk of accidental contact or accidental removal during use.

[0004] Traditional electron microscope connection methods are mostly split connections. The so-called split connection is that the light guide part is first inserted into the light source and fixed, and then the signal socket of the light guide part and the image processor are connected through the electron microscope line. In this scheme, the image signal needs to pass through an extra set of connectors, and the connectors at both ends need to be repeatedly plugged and unplugged, resulting in complicated operation, frequent failures, and poor image stability. In addition, the signal socket of the light guide connector is not waterproof, and a waterproof cap needs to be specially added during cleaning and disinfection, which poses a risk of water leakage.

[0005] The integrated connection can be directly inserted into the light guide socket, which has its own signal socket. The integrated design of the light guide connector can greatly improve image stability and operability, indirectly reduce the requirements for connector reliability, improve waterproof performance, and reduce the cost of a set of electron microscope lines. The integrated light guide connector and light guide socket are both designed with shielding, which greatly improves the electromagnetic compatibility performance and reliability.
