Description

Applied to tissue softness sensing device in living body

The present invention relates to a sensing device, particularly to an endoscope attachment, and has a sensing component that can detect the softness of tissue in a living body.

According to the tumor, the discovery of the tumor is generally known by means of touch or visual observation, and the observation is assisted by instruments such as ultrasonic waves or endoscopes. Among them, in the case of endoscopes, the main system will have softness of photography and light source devices. The tube extends into the living body and uses an external display to obtain information on the surface of the organ tissue in the body. Further, the tissue section is further removed for pathological examination. However, the endoscope can only provide information on the surface of the tissue for subcutaneous Tumors in tissues are still difficult to observe and judge.

The change of tissue softness is usually accompanied by the occurrence of lesions. For example, the subcutaneous tumor will make the tissue have different hardness than the normal tissue. However, it is still necessary to obtain the tumor information through the endoscope supersonic wave, and the endoscope is super. Sound waves are expensive and not widely available in general medical institutions. Therefore, if the purpose of measuring tissue elasticity in living organisms can be achieved in a simpler way, it can be used to detect the presence of subcutaneous tumors to assist in the diagnosis of diseases.
