The optical endoscope 4, ultrasonic probe 5, and operating instrument 13 are made of hard and elastic materials. The structure of the remaining parts is the same as that in Embodiment 1 to Embodiment 4.

In view of the above-mentioned technical solution, the handle 1 of the present invention is in the form of a straight handle or a curved handle. The function of the handle 1 is to ensure that the operator can operate the present invention stably, and the rotation of the casing 10 can be realized by operating the handle 1 through leverage The present invention can be provided with on the end face of handle 1 for optical endoscope 4, ultrasonic probe 5, the working channel A2 of operating apparatus 13 reuses, and water inlet pipe 7 and water outlet pipe 8 constitute loop so that the influence such as congestion in the operation cavity Operate sight of the substance for cleaning. Two channels can also be provided, for example, the working channel B3 is used for the optical endoscope 4 and the ultrasonic probe 5 respectively.

The casing 10 described in this application is a straight tube, an arc tube or a bent tube with a bending angle of 0° to 40°, and one end of the bent tube can be an arc-shaped structural pipe, as shown in Fig. 4 to Fig. 6. Because the function of the sleeve 10 is to guide each operating instrument into the medullary cavity of the fracture segment after cleaning. The cannula 10 is made of a material with a certain hardness and elastic bending suitable for the operation of the medullary cavity, or a hard tube with a certain amount of elasticity. The curvature formed by the elastic deformation is compatible with the curvature in the long tubular bone marrow cavity of the human body, so the casing 10 with curvature of different specifications and models can be provided to adapt to different fracture sites. The optical endoscope 4 and the ultrasonic probe 5 pass through the cannula 10 and enter the medullary cavity for observation while adjusting the entry length of the cannula 10 to make it close to the fracture end.

By adjusting the handle 1, leverage is used to adjust the direction close to the fracture end, the field of view of the optical endoscope 4 and the detection range of the ultrasonic probe 5, and at the same time moderately pull the distal end of the body to find the medullary cavity of the fracture end far away. And through the working channel A2 and/or the working channel B3, insert the guide wire into the medullary cavity of the distal fracture end to an appropriate length. The optical endoscope 4, the ultrasonic probe 5, and the cannula 10 are withdrawn, and the pulp is further reamed through the guide wire and the intramedullary nail is driven in.
