Because the biopsy forceps of the application are miniature, in the operation process of the whole signal processing board, the small lithium battery fixed on the battery module 16 supplies power, related components are low in power consumption and energy-saving, and the battery is fixed by the battery fixing buckle and is not easy to fall off.
To sum up, in this embodiment, the endoscope operation biopsy forceps device that provides, image wireless transmission who will acquire through miniature camera head is for display device, through the signal transmission of sending end and receiving terminal, and convert corresponding picture display on the display screen into, can save the supplementary foundation of image as later stage testing result in real time, because the camera is inlayed in biopsy forceps's draw-in groove, the volume that has reduced biopsy forceps, the pine that has avoided the camera takes off and drops, the sense of pain that has alleviateed the patient, make things convenient for the doctor to operate more.
Meanwhile, the outer surfaces of the camera and the signal transmission line are sleeved with transparent disposable protective sleeves, so that high-temperature disinfection can be avoided, and the micro camera can be recycled. And the LED lamp that the camera head was had can improve video display's definition in the detection, and makes things convenient for the better tissue of observing pathological change of doctor, accurate extraction target tissue sample. The handle part of the biopsy forceps is added with the anti-slip rubber, so that a good fixing effect is achieved.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
