[0023] Example: Figure 1-4 As shown, this utility model provides a technical solution, a visual percutaneous endoscopic circumferential saw system, including a mounting handle 1, a connecting saw tube 2 fixedly connected to the middle of the bottom surface of the mounting handle 1, a splicing block 3 snapped into the middle of the top surface of the mounting handle 1, an inner guide rod 4 fixedly inserted into the middle of the inner side of the splicing block 3 corresponding to the internal position of the connecting saw tube 2, and circular guide grooves are opened in the middle of both the mounting handle 1 and the connecting saw tube 2, and the outer side of the inner guide rod 4 is tightly fitted with the inner wall of the connecting saw tube 2;
[0024] A torque sensor 5 is fixedly connected to the end of the inner guide rod 4 at the position corresponding to the inside of the saw tube 2. A connecting threaded rod 6 is fixedly installed at the end of the torque sensor 5. A limiting end ring 7 is fixedly sleeved on the outer top of the connecting threaded rod 6. A connecting threaded sleeve 8 is threadedly sleeved on the outer side of the connecting threaded rod 6. A rotating saw head 9 is fixedly connected to one end of the outer side of the connecting threaded sleeve 8. The end of the connecting threaded rod 6 and the side of the limiting end ring 7 are tightly fitted together. A gap is left between the end face of the rotating saw head 9 and the end face of the connecting saw tube 2.
[0025] A monitoring mounting head 10 is fixedly connected to the end of the connecting threaded rod 6 at the position corresponding to the inner side of the rotating saw head 9. A mini camera 11 is embedded in the middle of the end face of the monitoring mounting head 10. A pressure sensor 12 is embedded in one side of the end of the monitoring mounting head 10, and a temperature sensor 13 is embedded in the other side. The torque sensor 5, the mini camera 11, the pressure sensor 12, and the temperature sensor 13 are all powered by an external power source. The rotating saw head 9 is installed onto the end of the mounting inner guide rod 4 through the cooperation between the connecting threaded rod 6 and the connecting threaded sleeve 8. The end of the rotating saw head 9 is limited by the limiting end ring 7. The external drive handle drives the mounting round handle 1 and the connecting saw tube 2 to rotate synchronously. The rotating saw head 9 cuts the patient's bone. The cutting position is monitored by the change of torque on the rotating saw head 9. The temperature and pressure inside the wound are monitored by the pressure sensor 12 and the temperature sensor 13. The mini camera 11 transmits real-time images of the inside of the wound. This effectively expands the function of the orthopedic trephine drill, ensuring that the inside of the wound can be monitored in real time during use, so that the position of the orthopedic trephine drill can be adjusted in real time, further improving the overall safety of the orthopedic trephine drill.
[0026] The mounting handle 1 has mounting slots 14 evenly spaced along the circumference on its outer side. The splicing block 3 has evenly spaced splicing rectangular slots 15 evenly spaced along the circumference on its outer side. A splicing small piece 16 is fixedly connected to the end face of the mounting handle 1 at a position corresponding to the inside of the splicing rectangular slot 15. A guide arc groove 17 is formed through the middle of one side of the inner guide rod 4. A data connection cable 18 is fixedly connected to the top of the inner guide rod 4. The outer side of the splicing small piece 16 fits tightly against the inner wall of the splicing rectangular slot 15. The input end of the data connection cable 18 is connected to the output end of each sensor, and the output end of the data connection cable 18 is connected to an external control terminal. The connecting block 3 can be used to attach the inner guide rod 4 and its components to the inside of the connecting saw tube 2. The mounting slot 14 can be used to connect the mounting handle 1 to the external drive handle. The interlocking rectangular slot 15 and the interlocking small block 16 limit the movement between the mounting handle 1 and the interlocking block 3. The material guide arc groove 17 is used to install external auxiliary instruments into the inside of the connecting saw tube 2 to expand the function of the orthopedic ring saw bone drill. The data connection line 18 transmits the data inside the orthopedic ring saw bone drill to the external control terminal for analysis, thereby effectively improving the overall assembly convenience and operation smoothness of the orthopedic ring saw bone drill.
[0027] The working principle and usage process of this utility model: Before using the orthopedic ring saw bone drill, this utility model needs to be assembled first. The inner guide rod 4 and its components can be snapped into the inside of the connecting saw tube 2 by splicing the round block 3. The mounting round handle 1 can be spliced with the external drive handle by the mounting slot 14. The mounting round handle 1 and the splicing round block 3 are limited by the cooperation between the splicing rectangular slot 15 and the splicing small block 16, so as to ensure that the connecting saw tube 2 can rotate synchronously with the inner guide rod 4.
[0028] External auxiliary instruments are installed inside the connecting saw tube 2 through the guide arc groove 17 to expand the function of the orthopedic trephine drill. Data inside the orthopedic trephine drill is transmitted to an external control terminal for analysis through the data connection line 18, thereby effectively improving the overall assembly convenience and operation smoothness of the orthopedic trephine drill.
[0029] When cutting the wound of the patient with the orthopedic ring saw bone drill, the rotating saw head 9 is installed to the end of the inner guide rod 4 by the cooperation between the connecting threaded rod 6 and the connecting threaded sleeve 8, and the end of the rotating saw head 9 is limited by the limiting end ring 7 to prevent the rotating saw head 9 from loosening during the cutting process. The external drive handle drives the mounting round handle 1 and the connecting saw tube 2 to rotate synchronously.
[0030] The saw head 9 is rotated to cut the patient's bone. Due to the different hardness of different parts of different bones, the data detected by the torque sensor 5 varies when the saw head 9 is rotated to different positions. The cutting position is monitored by the change of torque on the saw head 9 to prevent the saw head 9 from cutting nerves and blood vessels during the cutting process. At the same time, the temperature and pressure inside the wound are monitored by the pressure sensor 12 and the temperature sensor 13, and the situation inside the wound is transmitted in real time by the mini camera 11. This effectively expands the function of the orthopedic trephine saw and ensures that the trephine saw and bone drill can monitor the inside of the wound in real time during use, so that the position of the orthopedic trephine saw and bone drill can be adjusted in real time, further improving the overall safety of the orthopedic trephine saw and bone drill.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
