Description

Operation handle for confocal probe and confocal microscopic imaging device

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to an operating handle for a confocal probe and a confocal microscopic imaging device.

Background

Medical endoscopes are a requisite medical device for in vivo lesion exploration diagnosis and minimally invasive surgery, and are widely applied to various fields of clinical medicine. The endoscope observes the internal tissue on a macroscopic scale, identifies the suspicious region, clamps the suspicious tissue to the outside for histopathological diagnosis if necessary, but the process is a wounded process, and is often accompanied with bleeding, infection, early diagnosis omission and other phenomena, and has a certain risk. The laser confocal microscopic endoscope can realize the real-time high-resolution histopathological diagnosis of the internal organs without sampling biopsy, can use fluorescent contrast agent, has strong specificity, is an important instrument for noninvasive diagnosis of early lesions, and has great significance for early diagnosis of cancerations which are difficult to be found by the conventional endoscope.

In recent years, confocal laser microscopy imaging techniques have become increasingly widely used in clinical pathology biopsy. A confocal probe having a confocal microscope optical system is capable of focusing a laser beam on a biological tissue in a body cavity, extracting only the emitted light on the focal plane of an objective optical system from the emitted light from the irradiated biological tissue, and observing the biological tissue at a higher magnification than a normal endoscope optical system. Typically, a confocal probe is inserted into the channel of the endoscopic forceps and enters the body lumen with the endoscopic forceps channel, with its imaging range limited to the scope of the endoscopic camera. In many application scenarios (such as laparoscope or hysteroscope), since the lens tube is a hard tube, the direction of the front camera is fixed, which inevitably results in that many target positions are difficult to reach, and the complete area of the focus cannot be effectively detected.
