Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example 1, by Figure 1 , Figure 3 , Figure 5The present invention includes a hollow motor 2, which supports the entire device. A motor housing 209 is fixed to the outside of the hollow motor 2. A buckle 211, made of alloy material, is used to position the hollow motor 2. A handle 3 is bolted to the top of the hollow motor 2. The handle 3 has a curved shape, with its curvature varying along its length to conform to the natural curve of the human hand. A cable outlet 201 is fixed to the rear end of the top of the hollow motor 2, allowing for electrical connection to an external power source and control device for convenient control. The hollow motor 2 has a buckle 211 at its bottom, which is made of alloy material. The buckle 211 connects the hollow motor 2 to the bottom housing 203, which is also made of alloy material. The bottom housing 203 ensures the airtightness of the hollow motor 2. The motor housing 209 and the bottom housing 203 are fastened together by multiple connecting bolts 208. A silicon steel winding 205 is slidably connected inside the hollow motor 2. Multiple windings 210 are wound inside the silicon steel 205. The silicon steel windings 205 and the windings 210 cooperate to allow the positioning tube 202 to rotate. A hollow shaft 204 is provided inside the silicon steel winding 205. The hollow shaft 204 is made of alloy material and is used to position the connecting tube 212. The connecting tube 212, also made of alloy material, is slidably connected inside the hollow shaft 204 and is used to position the positioning tube 202. The positioning tube 202 is fixed inside the connecting tube 212. The ring saw 1 can be rotated by rotation. The positioning tube 202 has a positioning hole 214 inside, which provides a channel for the ring saw 1. The ring saw 1 is fixed to the inner wall of the positioning hole 214. The ring saw 1 is made of alloy material. The ring saw 1 is used to fix the ring saw head 101. A pressure rod 401 is detachably connected inside the ring saw 1. The pressure rod 401 is made of alloy material and is used to remove the debris generated during cutting. A surgical hammer 5 is also provided at the top of the handle 3. The surgical hammer 5 is used to apply the required force to the pressure rod 401.

[0028] Example 2, based on Example 1, is... Figure 2 , Figure 4 , Figure 6As shown, the connecting tube 212 has positioning rings 213 fixed at both ends. The positioning rings 213 are made of alloy material and are used to engage the hollow shaft 204. The upper positioning ring 213 has a top bearing 207 at its top, with its inner ring fixedly connected to the positioning tube 202 and its outer ring engaged with the upper end of the hollow motor 2. The lower positioning ring 213 has a bottom bearing 206 at its bottom, with its inner ring fixedly connected to the positioning tube 202 and its outer ring engaged with the bottom outer shell 203. The cooperation of the bottom bearing 206 and the top bearing 207 ensures that the positioning tube 202 can rotate while preventing it from moving up and down. The handle 3 has a handle through hole 301 inside, which provides a path for the bone chisel hammer 4. The positioning hole... 214 has the same inner diameter as the handle through hole 301. The bottom of the ring saw 1 is fixed with multiple ring saw heads 101. The ring saw heads 101 are made of alloy material and are used to cut bone. The bottom of the pressure rod 401 is fixed with a pressure head 402. The pressure head 402 has a beveled structure and is made of alloy material. The pressure head 402 facilitates the removal of debris generated during cutting. The top of the pressure rod 401 is also fixed with a bone chisel hammer 4. The bone chisel hammer 4 facilitates the application of force by the surgical hammer 5. The outside of the surgical hammer 5 is fixed with a hammer head 503. The hammer head 503 is made of alloy material. The bottom of the hammer head 503 is fixed with a shaft 502. The shaft 502 is made of alloy material. The bottom of the shaft 502 is fixed with a bone chisel handle 501. The bone chisel handle 501 and the shaft 502 cooperate to facilitate the movement of the surgical hammer 5.

[0029] When using this equipment, the operator can connect the entire device to an external power source via the output cable 201, allowing the external control device to control the rotation of the hollow motor 2. The operator then places the entire device at the desired drilling position. The external controller then controls the rotation of the hollow motor 2, which in turn drives the silicon steel winding 205 and the winding 210 to work together, thereby rotating the hollow shaft 204, which in turn rotates the positioning tube 202, which in turn rotates the ring saw 1, and thus the ring saw head 101. The operator then holds the handle 3 and pushes it to make the ring saw head 101 drill into the desired drilling position. At this time, due to the hollow motor 2, the drilling speed can be reduced... To reduce the overall weight of the equipment and ensure the stability of the drilling process, when the ring saw 1 is rotated to the desired position, the external controller controls the hollow motor 2 to stop working. The operator then inserts the bone chisel hammer 4 into the ring saw 1, causing the pressure head 402 to slide to the bottom of the ring saw 1. The operator holds the bone chisel handle 501 to apply force to the pressure rod 401, causing the bone chisel hammer 4 to move downwards. This allows the pressure head 402 to collect the drilling debris inside the pressure rod 401. Simultaneously, the operator can remove the lesion by continuing to insert the bone chisel hammer 4. Finally, the operator removes the bone chisel hammer 4, thus completing the cleaning of the bone lesion.

[0030] Example 3, based on Example 1, is... Figures 7-8 As shown, the ring saw 1 is detachably connected to an endoscope connection cable 601, which allows the endoscope 602 to be connected to the display screen 6. The endoscope 602 is fixed at the bottom of the endoscope connection cable 601. The endoscope 602 is used to monitor the specific location of the lesion. The display screen 6 is fixed at the top of the endoscope connection cable 601, and the display screen 6 can display the monitoring images of the endoscope 602.

[0031] When using this device, the operator can also remove the pressure head 402 and slide the endoscope 602 into the ring saw 1, so that the specific location of the lesion can be monitored through the endoscope 602. At the same time, the data can be transmitted to the display screen 6 through the endoscope connection cable 601, so that external observation can be realized through the display screen 6.

[0032] The working process of this utility model is as follows: When using this equipment, the operator can connect the entire equipment to an external power source through the output line 201, and at the same time, the external control device can control the rotation of the hollow motor 2. The operator then places the entire equipment at the required drilling position. The external controller then controls the rotation of the hollow motor 2, which in turn drives the silicon steel winding 205 and the winding 210 to work together, thereby driving the hollow shaft 204 to rotate, which in turn drives the positioning tube 202 to rotate, thereby driving the ring saw 1 to rotate, and thus driving the ring saw head 101 to rotate. The operator then holds the handle 3 and pushes the handle 3 to make the ring saw head 101 drill into the required drilling position. At this time, due to the hollow motor 2, the weight of the entire equipment is reduced, thereby ensuring the stability of the drilling process. Furthermore, when the ring saw 1 rotates to the required position, the external controller controls the hollow... Motor 2 stops working. The operator then inserts the bone chisel hammer 4 into the ring saw 1, causing the pressure head 402 to slide to the bottom of the ring saw 1. The operator holds the bone chisel handle 501, applying force to the pressure rod 401, causing the bone chisel hammer 4 to move downwards. This allows the pressure head 402 to collect drilling debris inside the pressure rod 401. The operator can further penetrate the bone chisel hammer 4 to remove the lesion. The operator then removes the bone chisel hammer 4, completing the cleaning of the bone lesion. The operator can also remove the pressure head 402 and slide the endoscope 602 into the ring saw 1. The endoscope 602 can then monitor the specific location of the lesion, and the data can be transmitted to the display screen 6 via the endoscope connection cable 601 for external observation.
