Description

Technical Field

[0001] The utility model specifically relates to the technical field of medical equipment, and in particular to a portable ultra-thin endoscope system for liver puncture. Background Art

[0002] As an important extension of the doctor's vision, the endoscope can observe the condition of organ tissues without opening the cavity or minimally invasive surgery. It can be directly inserted into the human body through holes and surgical incisions to directly observe whether certain areas have lesions and the extent of the lesions, so as to determine the best treatment measures and perform the most accurate surgery. As the demand direction changes, endoscopes are gradually developing in the direction of portability and intelligence. Liver puncture is very traumatic, which makes many patients resist it, and liver biopsy is not used as a routine examination in clinical practice. However, the accuracy rate of liver puncture biopsy is above 80%, which is a better means of examination.

[0003] The existing endoscope system generally consists of a display component, a cable, a hand-held handle and an insertion component. The insertion component collects images and transmits them to the display component through the cable for display.

[0004] However, the insertion parts of the above-mentioned endoscope system are generally thick, and the safety and comfort of endoscopic examination are poor, which causes greater trauma and is difficult for patients to accept. Therefore, there is room for improvement. Utility Model Content
