[0022] Referring to Figures 1-6 , a medical bendable grinding tool provided by the present utility model includes an inner tube 1. A sleeve 3 is fixedly connected to the circumferential surface of the inner tube 1. A transmission rod 8 is slidably connected inside the inner tube 1. A rotating block 13 is rotatably connected inside the transmission rod 8. A grinding cutter head 5 is fixedly connected to the left end of the rotating block 13. The grinding cutter head 5 is located inside the sleeve 3 and is slidably connected to the sleeve 3. An angle adjustment assembly is installed inside the sleeve 3, and the angle adjustment member cooperates with the rotating block 13 and is used to adjust the angle of the grinding cutter head 5. A lighting assembly is installed at the left end of the sleeve 3. The lighting assembly includes a support plate 10, a light strip 7, and a support rod 9. The left end of the sleeve 3 is adhesively connected with a support plate 10 using glue. The left end of the support plate 10 is fixedly connected with a light strip 7 through a plurality of support rods 9. The light strip 7 is sleeved on the circumferential surface of the grinding cutter head 5. During operation, with the function of the lighting assembly, the present utility model can illuminate the position where the grinding cutter head 5 operates. When a doctor operates on a fine position deep inside a patient's body, with the function of the lighting assembly, it is convenient for the doctor to observe clearly, thereby improving the accuracy of the doctor's operation.

[0023] Furthermore, the support rod 9 is made of a rubber strip. During operation, when the grinding cutter head 5 performs a bending operation, with the function of the support rod 9, the light strip 7 can smoothly follow the bending of the grinding cutter head 5, so that the light strip 7 can always illuminate the position where the grinding cutter head 5 operates.

[0024] Furthermore, a notch 6 is formed on the circumferential surface of the sleeve 3. The width of the notch 6 is greater than the diameter of the grinding cutter head 5. During operation, the existence of the notch 6 facilitates the smooth bending operation of the grinding cutter head 5.

[0025] Furthermore, an outer tube 2 is rotatably connected to the outer circumferential surface of the inner tube 1. A circular hole is formed on the right end surface of the outer tube 2. During operation, a medical staff holds the outer tube 2 and simultaneously connects an external power source, so that the connection end of the power source is connected to the inner tube 1 through the circular hole. In this way, power can be provided for the inner tube 1 to rotate, and with the mutual cooperation of the sleeve 3, the transmission rod 8, and the angle adjustment member, power can be provided for the grinding cutter head 5 to operate.

[0026] Furthermore, a sliding hole 4 is formed in the circumferential surface of the inner tube 1. A threaded rod 11 is slidably connected inside the sliding hole 4. The threaded rod 11 is fixedly connected to the transmission rod 8. A nut 12 is threadedly connected to the circumferential surface of the threaded rod 11. One end of the nut 12 close to the inner tube 1 is fixedly connected with a gasket 16. The nut 12 is in close fit with the inner tube 1 through the gasket 16. The angle adjusting member includes an inclined block 15, a convex block 14 and a roller 17. The inclined block 15 is fixedly connected to the inner wall of the sleeve 3. The convex block 14 is fixedly connected to one side of the rotating block 13 close to the inclined block 15. The roller 17 is rotatably connected inside the convex block 14. The roller 17 is matched with the inclined block 15. During operation, when the nut 12 is rotated to separate the gasket 16 from the inner tube 1, the threaded rod 11 can be pushed along the sliding hole 4 towards the grinding cutter head 5, thereby driving the transmission rod 8 to move inside the inner tube 1. The movement of the transmission rod 8 drives the movement of the rotating block 13. The rotating block 13 drives the movement of the convex block 14 and the roller 17. Under the mutual cooperation of the inclined block 15, the grinding cutter head 5 and the rotating block 13 rotate, so that the grinding cutter head 5 is gradually bent sideward. The bent grinding cutter head 5 can operate on deeper positions in the patient's body.

[0027] Working principle:

[0028] During use, after the whole device is inserted into the patient's body, it can operate on the position in the patient's body that needs to be ground. During the grinding operation, the light strip 7 emits light to illuminate the position to be operated in the patient's body, so that the staff can perform the grinding work more accurately. When side grinding is required in the patient's body, rotate the nut 12 to separate the gasket 16 from the inner tube 1. Then, the threaded rod 11 can be pushed along the sliding hole 4 towards the grinding cutter head 5, thereby driving the transmission rod 8 to move inside the inner tube 1. The movement of the transmission rod 8 drives the movement of the rotating block 13. The rotating block 13 drives the movement of the convex block 14 and the roller 17. Under the mutual cooperation of the inclined block 15, the grinding cutter head 5 and the rotating block 13 rotate, so that the grinding cutter head 5 is gradually bent sideward. The bent grinding cutter head 5 can perform side grinding work on deeper positions in the patient's body.
