Further, needle knife front end is set as flat blade cutter, lancet, elevator, clamps or cut.

Further, the superfine endoscope includes tube body, is provided with optical imaging system in the tube body, the optics at As system includes sequentially connected self-focusing lens, imaging fiber beam, imaging eyepiece group and output interface, the self-focusing lens Setting, which is located at around optical imaging system in tube body end, the tube body, is provided with fibre-optic bundle, the fibre-optic bundle One end extends at self-focusing lens, and the other end is connected with conductive interface.

Further, it is set as being detachably connected between the needle knife and hollow needle body.

The beneficial effects of the present invention are：

1, the present invention is operated by being provided with superfine endoscope in hollow needle body and the needle knife in hollow needle body end portion being arranged in When superfine endoscope and needle knife can enter in tissue simultaneously, blind knife is become visual using endoscope, substantially increases operation peace Quan Xing, accuracy.

2, the present invention using outer diameter be less than 1mm ultra-thin glass fiber, by be provided with fibre-optic bundle and conductive interface and Imaging fiber, imaging eyepiece group and output interface are directly accessed in video camera simultaneously, optimize the mechanism of endoscope, alleviate interior peep Mirror weight, facilitates surgical procedure；

3, needle knife mirror of the present invention is most importantly realized function other than being realized visual needle knife operation using superfine endoscope Part is placed on except superfine endoscope in the form of outer tube, and outer tube head end is function achievement unit beyond endoscope lens part Point, shape can be flat blade cutter, lancet, elevator, clamp, cuts, to achieve the purpose that visually to loosen to diseased soft tissue.

4, needle knife mirror of the present invention both can be used needle knife medicine principle, modern minimal invasive surgery can also be used in operating principle Principle, function multiplication.
