Illustratively, the handle housing accommodates the image capturing device 110 and the wireless transmitting device 120 therein, the handle housing 110 is provided with a signal transmission window, the signal transmission window corresponds to the wireless transmitting device 120, and a detachable signal modifying sheet is embedded on the signal transmission window; the image acquisition device 110 can acquire the image information of the target part, and the wireless transmitting device 120 converts the image information into wireless information and transmits the wireless information to the medical host; the medical host converts the wireless information into image information, so that a doctor can observe the target part more clearly and analyze the target part more finely; when the device is applied to medical operation, the precision of the operation can be effectively improved.

Illustratively, the image capturing device 110 includes a lens assembly and an image sensor, the lens assembly is a combination of a convex lens and a filter lens for properly projecting the light of the target portion onto the image sensor.
