Laparoscopic camera handle with high stability

Abstract

The invention discloses a laparoscopic camera handle with high stability, and belongs to the technical field of medical instruments. Main points of a technical scheme comprise a shell with one end asan open end, an end cover arranged at the open end of the shell, an inn shell positioned in the shell and fixedly connected with the end cover, and a 3MOS sensor positioned in the inner shell. One side of the 3MOS sensor is fixedly provided with a fixing block. The end cap is inserted with a fixing bolt for fixing the fixing block. The end cap is provided with a light transmission hole corresponding to the position of the 3MOS sensor, and a lens group is arranged at the light transmission hole. The invention has the advantages of stable imaging, good anti-jamming performance and good dust-proof and waterproof effect.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and more specifically relates to a high-stability laparoscopic camera handle. Background technique [0002] A laparoscope is a medical instrument with a tiny camera, which is used in conjunction with a monitor, an image processor, and a cold light source to complete the operation. Wherein, the laparoscope includes a camera handle, and the camera handle is used to enter the patient's body to take images of the internal organs of the patient. The most important component inside the camera handle is the 3MOS sensor, such as figure 1 As shown, the built-in prism of the 3MOS sensor can precisely separate the three primary colors of light, which is then processed by a dedicated sensor to produce excellent color reproduction. [0003] However, during the use of the camera handle, the interference of external factors often affects the imaging of the camera handle. On the one hand, the came...

Problems solved by technology

[0003] During the use of the camera handle, the interference of external factors often affects the imaging of the camera handle.

On the one hand, the camera handle is used in a special environment and needs to be in contact with human body fluids, and it needs to be disinfected with disinfectant before and after use. The infiltration of liquid will easily affect the spectral accuracy of the 3MOS sensor, and even cause damage to the camera handle; on the other hand, the external pulse The interference of the sensor will affect the color reproduction of the separated three-color light, making it difficult to guarantee the imaging quality of the camera handle
