[0016] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0017] In the above scheme, when the device needs to be cooled, the first motor is started, and the output end of the first motor drives the first gear to rotate, the first gear drives the second gear and the rotating column to rotate, and the rotating column drives the drill bit to rotate, so that the drill bit drills into the patient's skull, and the spray component is started at the same time. When the drill bit contacts the skull, the spray component can cool the area between the drill bit and the patient's skull, which can effectively reduce the temperature of the skull, thereby reducing the risk of thermal injury and protecting the surrounding tissues and nerves of the skull from damage, thereby improving the safety of the operation. When the monitoring component detects that the temperature of the drill bit is high, the cooling component is started to cool the drill bit to prevent the drill bit from excessive wear due to high temperature, thereby ensuring the cutting efficiency and surgical effect of the drill bit during the operation, and cooperating with the spray component to doubly cool the drill bit and the patient's skull, which can not only extend the service life of the drill bit and improve the drilling accuracy, but also reduce the risk of thermal injury to the patient's skull and improve the efficiency of the operation.

[0018] When it is necessary to cool the area between the drill bit and the patient's skull, start the water pump to extract the coolant in the water tank through the water pipe. The extracted coolant enters the connecting pipe through the water pump, enters the first annular pipe, the shunt pipe and the second annular pipe through the connecting pipe, and is sprayed out through the first nozzle and the second nozzle. The first nozzle is responsible for spraying coolant onto the drill body of the drill bit, effectively dispersing and taking away a large amount of heat generated by friction, preventing the drill bit from overheating as a whole, thereby extending the service life of the drill bit. The second nozzle is responsible for spraying coolant onto the drill tip of the drill bit, which can quickly reduce the temperature between the drill tip and the skull, reduce the risk of thermal damage, and maintain the sharpness and cutting efficiency of the drill tip, ensure the accuracy and safety of the operation, and reduce the smoke and splashes generated by high temperature, thereby reducing the risk of infection during the operation.

[0019] When the drill bit needs to be cooled, the water pump is started to extract the coolant in the water tank through the water pipe. The extracted coolant enters the connecting pipe through the water pump, and then enters the water inlet pipe through the connecting pipe, enters the water inlet channel and the water inlet area through the water inlet pipe, and then enters the connecting port, the water outlet area, and the water outlet channel through the water inlet area, and enters the water tank through the water outlet pipe for circulation. The circulation of the coolant can quickly reduce the temperature of the drill bit, reduce the thermal stimulation during the operation and the heat and wear caused by friction, prevent the drill bit from softening or deforming due to high temperature, maintain the original sharpness and cutting performance of the drill bit, and thus improve the cutting efficiency.

[0020] When it is necessary to monitor the temperature of the drill bit, when the temperature of the drill bit is high, the temperature of the drill bit is transferred to the heat dissipation tube through the rotating column and the drill bit, and the heat enters the rectangular sleeve through the heat dissipation hole, causing the air in the rectangular sleeve to expand and push the sliding plate to move upward. The first spring is compressed, and when the sliding plate contacts the sensor, the cooling component is activated to cool the drill bit to avoid damage to the skull and surrounding tissues caused by excessive temperature of the drill bit.

[0042] When the device is needed, the first motor 108 is started, and the output end of the first motor 108 drives the first gear 109 to rotate, and the first gear 109 drives the second gear 110 and the rotating column 105 to rotate, and the rotating column 105 drives the drill bit 106 to rotate, so that the drill bit 106 drills into the patient's skull position, and the spray component is started at the same time. When the drill bit 106 contacts the skull, the spray component can cool the area between the drill bit 106 and the patient's skull, which can effectively reduce the temperature of the skull, thereby reducing the risk of thermal injury and protecting the surrounding tissues and nerves of the skull from damage, thereby improving the safety of the operation. When the monitoring component detects that the temperature of the drill bit 106 is high, the cooling component is started to cool the drill bit 106 to prevent the drill bit 106 from excessive wear due to high temperature, thereby ensuring the cutting efficiency and surgical effect of the drill bit 106 during the operation, and the spray component can be used to cool the drill bit 106 and the patient's skull, which can not only extend the service life of the drill bit 106 and improve the drilling accuracy, but also reduce the risk of thermal injury to the patient's skull and improve the efficiency of the operation.

[0043] like Figure 3As shown, the spray assembly includes a water tank 201, which is fixedly connected to the top of the horizontal plate 102, a water pipe 202 is fixedly connected to one side of the water tank 201, a water pump 203 is fixedly connected to the top of the horizontal plate 102, one end of the water pipe 202 is fixedly connected to the water pump 203, the other end of the water pump 203 is fixedly connected to a connecting pipe 204, one end of the connecting pipe 204 is fixedly connected to a first annular pipe 205, a plurality of first nozzles 206 are fixedly connected to the outer surface of the first annular pipe 205, the first nozzle 206 is in a straight state, four shunt pipes 207 are fixedly connected to the outer surface of the first annular pipe 205, the bottom ends of the four shunt pipes 207 are fixedly connected to a second annular pipe 208, the outer surface of the second annular pipe 208 is fixedly connected to a second nozzle 209, the second nozzle 209 is in an inclined state, and the first annular pipe 205 and the second annular pipe 208 are both arranged outside the drill bit 106.

[0044] When it is necessary to cool the area between the drill bit 106 and the patient's skull, the water pump 203 is started to extract the coolant in the water tank 201 through the water pipe 202. The extracted coolant enters the connecting pipe 204 through the water pump 203, enters the first annular pipe 205, the shunt pipe 207 and the second annular pipe 208 through the connecting pipe 204, and is ejected through the first nozzle 206 and the second nozzle 209. The first nozzle 206 is responsible for spraying coolant to the drill body of the drill bit 106, effectively dispersing and taking away a large amount of heat generated by friction, preventing the drill bit 106 from overheating as a whole, thereby extending the service life of the drill bit 106. The second nozzle 209 is responsible for spraying coolant to the drill tip of the drill bit 106, which can quickly reduce the temperature between the drill tip and the skull, reduce the risk of thermal damage, and maintain the sharpness and cutting efficiency of the drill tip, ensure the accuracy and safety of the operation, and reduce the smoke and splashes generated by high temperature, thereby reducing the risk of infection during the operation.

[0045] like Figure 4As shown, the cooling assembly includes a cooling channel 210, and the cooling channel 210 is opened in the middle of the drill bit 106. The bottom end of the rotating column 105 is fixedly connected with a baffle 211, and the baffle 211 is set in a wave shape. The bottom end of the baffle 211 is provided with a connecting port 216. The round block 104 and the rotating column 105 are provided with a water inlet channel 212 and a water outlet channel 213. The baffle 211 divides the inside of the cooling channel 210 into a water inlet area 214 and a water outlet area 215. The water inlet area 214 and the water outlet area 215 are connected through the connecting port 216. The water inlet area 214 is connected to the water inlet channel 212, and the water outlet area 215 is connected to the water outlet channel 213. The top of the water outlet channel 213 is fixedly connected with a water outlet pipe 217, and one end of the water outlet pipe 217 is fixedly connected to the water tank 2 01, the top of the water inlet channel 212 is fixedly connected with a water inlet pipe 218, one end of the water inlet pipe 218 is fixedly connected to the connecting pipe 204, the water outlet pipe 217 and the water inlet pipe 218 pass through the horizontal plate, a plurality of heat-conducting blocks 251 are fixedly connected to the inside of the drill bit 106, one end of the heat-conducting block 251 extends into the cooling channel 210, and the heat-conducting block 251 is opposite to the bending part of the baffle 211, the baffle 211 and the heat-conducting block 251 set the water inlet area 214 and the water outlet area 215 as a curved channel, a through hole 252 is opened on the heat-conducting block 251, the other end of the heat-conducting block 251 is fixedly connected with a sticky ring 254 located inside the drill bit 106, the bottom end of the baffle 211 is fixedly connected with a sticky block 253 located inside the drill bit 106, and the sticky ring 254 and the sticky block 253 are both sticky metals.

[0046] When the drill bit 106 needs to be cooled, the water pump 203 is started to extract the coolant in the water tank 201 through the water pipe 202. The extracted coolant enters the connecting pipe 204 through the water pump 203, and then enters the water inlet pipe 218 through the connecting pipe 204, enters the water inlet channel 212 and the water inlet area 214 through the water inlet pipe 218, and then enters the connecting port 216, the water outlet area 215, and the water outlet channel 213 through the water inlet area 214, and enters the water tank 201 through the water outlet pipe 217 for circulation. Through the circulation of the coolant, the temperature of the drill bit 106 can be quickly reduced, the thermal stimulation during the operation and the heat and wear caused by friction can be reduced, the drill bit 106 can be prevented from softening or deforming due to high temperature, and the original sharpness of the drill bit 106 can be maintained. The baffle 211 is wavy in shape, and the baffle 211 and the heat-conducting block 251 set the water inlet area 214 and the water outlet area 215 as a curved channel. The coolant will flow in the curved channel, and the coolant can be retained in the curved channel for a long time. The heat-conducting block 251 can transfer the heat of the drill bit 106 to the coolant flowing through the curved channel, so that the cooling effect is better. If the drill bit 106 breaks or fractures during the drilling process, the fragments of the drill bit 106 will splash everywhere and cause harm to medical staff and patients. By setting the sticky block 253 and the sticky ring 254, when the drill bit 106 breaks, the sticky block 253 and the sticky ring 254 can stick to the fragments of the drill bit 106, so as to prevent the fragments from splashing everywhere.

A plurality of heat dissipation holes 221 are provided on the heat dissipation tube 220, and the inner wall of the rectangular sleeve 219 is slidably connected with a sliding plate 222, and a first spring 223 is fixedly connected between the inner wall of the rectangular sleeve 219 and the sliding plate 222, and the inner wall of the rectangular sleeve 219 is fixedly connected with a sensor 224.

[0048] When it is necessary to monitor the temperature of the drill bit 106, when the temperature of the drill bit 106 is high, the temperature of the drill bit 106 is transferred to the heat dissipation tube 220 through the rotating column 105 and the drill bit 106, and the heat enters the rectangular sleeve 219 through the heat dissipation hole 221, causing the air in the rectangular sleeve 219 to expand and push the sliding plate 222 to move upward, and the first spring 223 is compressed. When the sliding plate 222 contacts the sensor 224, the cooling component is activated to cool the drill bit 106 to avoid damage to the skull and surrounding tissues caused by excessive temperature of the drill bit 106.

[0049] like Figure 6As shown, the inner walls of the water inlet channel 212 and the water outlet channel 213 are both rotatably connected with sealing plates 225 , and the outer surfaces of the two sealing plates 225 are both fixedly connected with rotating rods 226 , which are rotatably penetrated through one end of the round block 104 .

[0050] By providing the sealing plate 225 and the rotating rod 226 , rotating the rotating rod 226 can drive the sealing plate 225 to seal or open the water inlet channel 212 and the water outlet channel 213 , so that when the temperature of the drill bit 106 is high, the cooling component can cool down the drill bit 106 .

[0051] like Figure 7 As shown, the outer surface of the round block 104 is fixedly connected to a U-shaped shell 227, one end of the two rotating rods 226 are rotatably connected to the inner wall of the U-shaped shell 227, the outer surfaces of the two rotating rods 226 are fixedly connected to the third gear 228, the inner wall of the U-shaped shell 227 is slidably connected to a rack plate 229, one side of the rack plate 229 is fixedly connected to a pull block 230, the rack plate 229 slides through one end of the U-shaped shell 227, the upper and lower parts of the rack plate 229 are symmetrically fixedly connected to the first magnet 231, and the inner wall of the U-shaped shell 227 is fixedly connected to the second magnet 232 and the third magnet 233.

[0052] When the temperature of the drill bit 106 is high and the water inlet channel 212 and the water outlet channel 213 need to be opened, the pull block 230 is pulled, and the pull block 230 drives the rack plate 229 to move outward in the U-shaped shell 227, and the rack plate 229 drives the two third gears 228 to rotate at the same time. When the first magnet 231 slides close to the first spring 223, the rack plate 229 is restricted by the attraction of the first spring 223, and the sealing plate 225 rotates from a horizontal state to a vertical state, so that the water inlet channel 212 and the water outlet channel 213 are opened. When the first magnet 231 is close to the second magnet 232, the sealing plate 225 rotates from a vertical state to a horizontal state, so that the water inlet channel 212 and the water outlet channel 213 are closed.

[0053] like Figure 8 As shown, the two vertical plates 101 are both provided with lifting grooves 234, and the horizontal plate 102 is slidably connected to the inner walls of the two lifting grooves 234. The top of the left vertical plate 101 is fixedly connected with an L-shaped plate 235, and the inner side of the L-shaped plate 235 is fixedly connected with a second motor 236, and the output end of the second motor 236 is fixedly connected with a threaded rod 237, and the threaded rod 237 rotates and passes through the upper end of the left vertical plate 101, and the horizontal plate 102 is threadedly connected to the threaded rod 237, and the inner wall of the right vertical plate 101 is fixedly connected with a limiting rod 238, and the horizontal plate 102 is slidably connected to the limiting rod 238.

[0054] When the height of the drill bit 106 needs to be adjusted, the second motor 236 is started, and the output end of the second motor 236 drives the threaded rod 237 to rotate. Through the action of the thread, the threaded rod 237 can drive the cross plate 102 to move along the length direction of the limiting rod 238. The cross plate 102 drives the round block 104, the rotating column 105 and the drill bit 106 to move, and the height of the drill bit 106 is adjusted. This helps the staff to better control the drilling depth during the operation, ensure that the drill bit 106 can reach the predetermined intracranial area, and ensure that the surgical effect is optimal.

[0055] like Fig. 9 As shown, the bottom ends of the two vertical plates 101 are each provided with a bottom plate 239, the top ends of the two bottom plates 239 are each fixedly connected with an arc plate 240, a connecting shaft 241 is fixedly connected to the arc plate 240, the vertical plate 101 is rotatably connected to the outer surface of the connecting shaft 241, and a limiting component for limiting the vertical plate 101 is provided on the arc plate 240.

[0056] By providing the arc plate 240 and the connecting shaft 241, when the angle of the drill bit 106 needs to be adjusted, the vertical plate 101 is pulled to make the two vertical plates 101 rotate on the connecting shaft 241, the vertical plate 101 drives the horizontal plate 102 to rotate, and the horizontal plate 102 drives the round block 104, the rotating column 105 and the drill bit 106 to rotate. When the drill bit 106 is rotated to an angle suitable for rotating the patient's skull, the angle of the drill bit 106 is limited by the limiting component, so that the staff can locate the drilling position more accurately, ensuring that the drill bit 106 can accurately enter the predetermined intracranial area, thereby improving the accuracy and effect of the operation.

[0057] like Fig. 9 As shown, the limiting component includes a rectangular shell 242, which is fixedly connected to one side of the left end arc plate 240, and the inner wall of the rectangular shell 242 is slidably connected with a rectangular block 243, and a second spring 244 is fixedly connected between the inner wall of the rectangular shell 242 and the rectangular block 243, and a handle 245 is fixedly connected to one side of the rectangular block 243, and the handle 245 slides through one side of the rectangular shell 242, and the top of the rectangular block 243 is fixedly connected with a connecting plate 246, and the connecting plate 246 slides through the upper end of the rectangular shell 242, and one side of the connecting plate 246 is fixedly connected with a latch 247, and the latch 247 slides through the left end of the arc plate 240, and a plurality of slots 248 that cooperate with the latch 247 are opened on the left end of the vertical plate 101.

[0058] When it is necessary to limit the vertical plate 101, pull the handle 245, the handle 245 drives the rectangular block 243 to slide in the rectangular shell 242, the second spring 244 is compressed, the rectangular block 243 drives the connecting plate 246 to slide, the connecting plate 246 drives the pin 247 to leave the slot 248, then, rotate the vertical plate 101 to adjust the angle of the drill bit 106, when it is adjusted to a suitable position, release the handle 245, the second spring 244 rebounds, the rectangular block 243 drives the connecting plate 246 to slide, the connecting plate 246 drives the pin 247 to insert into the slot 248, and the vertical plate 101 is restricted to prevent the vertical plate 101 from rotating at will.

[0059] like Figure 8 and Fig.10 As shown, the front and rear of the horizontal plate 102 are symmetrically fixedly connected with T-shaped sliding blocks 249 , and the vertical plate 101 is provided with T-shaped sliding grooves 250 that cooperate with the T-shaped sliding blocks 249 .

[0060] By providing a T-shaped slider 249 and a T-shaped groove 250, when the horizontal plate 102 slides on the vertical plate 101, the horizontal plate 102 can drive the T-shaped slider 249 to slide in the T-shaped groove 250. The T-shaped groove 250 can limit and guide the T-shaped slider 249 and the horizontal plate 102, and can also improve the stability of the horizontal plate 102 during the sliding process.

[0061] The workflow of the technical solution of the present invention is as follows:

[0062] First, pull the handle 245, the handle 245 drives the rectangular block 243 to slide in the rectangular shell 242, the second spring 244 is compressed, the rectangular block 243 drives the connecting plate 246 to slide, the connecting plate 246 drives the latch 247 to leave the slot 248, pull the vertical plate 101, so that the two vertical plates 101 rotate on the connecting shaft 241, the vertical plate 101 drives the horizontal plate 102 to rotate, the horizontal plate 102 drives the round block 104, the rotating column 105 and the drill bit 106 to rotate, and when the drill bit 106 is rotated to an angle suitable for drilling bones in the patient's skull, The handle 245 is released, the second spring 244 rebounds, the rectangular block 243 drives the connecting plate 246 to slide, and the connecting plate 246 drives the latch 247 to be inserted into the slot 248 to restrict the vertical plate 101 to prevent the vertical plate 101 from rotating at will. Then, the second motor 236 is started, and the output end of the second motor 236 drives the threaded rod 237 to rotate. Through the action of the thread, the threaded rod 237 can drive the horizontal plate 102 to move along the length direction of the limit rod 238, and the horizontal plate 102 drives the round block 104, the rotating column 105 and the drill bit. The drill 106 is moved, the height of the drill 106 is adjusted, and the drill 106 is adjusted to a suitable height. By starting the first motor 108, the output end of the first motor 108 drives the first gear 109 to rotate, the first gear 109 drives the second gear 110 and the rotating column 105 to rotate, and the rotating column 105 drives the drill 106 to rotate, so that the drill 106 drills into the patient's skull position, and at the same time, the water pump 203 is started to extract the coolant in the water tank 201 through the water pipe 202, and the extracted coolant enters the connecting pipe 201 through the water pump 203. 04, enters the first annular tube 205, the shunt tube 207 and the second annular tube 208 through the connecting tube 204, and is sprayed out through the first nozzle 206 and the second nozzle 209. The first nozzle 206 is responsible for spraying coolant to the drill body of the drill bit 106, effectively dispersing and taking away a large amount of heat generated by friction, preventing the drill bit 106 from overheating as a whole, thereby extending the service life of the drill bit 106. The second nozzle 209 is responsible for spraying coolant to the drill tip of the drill bit 106, which can quickly reduce the temperature between the drill tip and the skull and reduce the risk of thermal damage.

[0063] When the temperature of the drill bit 106 is high, the temperature of the drill bit 106 is transferred to the heat dissipation tube 220 through the rotating column 105 and the drill bit 106, and the heat enters the rectangular sleeve 219 through the heat dissipation hole 221, so that the air in the rectangular sleeve 219 expands and pushes the sliding plate 222 to move upward, and the first spring 223 is compressed. When the sliding plate 222 contacts the sensor 224, the pull block 230 is pulled, and the pull block 230 drives the rack plate 229 to move outward in the U-shaped shell 227, and the rack plate 229 drives the two third gears 228 to rotate at the same time. When the first magnet 231 slides close to the first spring 223, the rack plate 229 is restricted by the attraction of the first spring 223, and the sealing plate 225 is rotated from a horizontal state to a vertical state, so that the water inlet channel 212 is closed. The coolant in the water tank 201 is extracted by the water pump 203, and the extracted coolant enters the water inlet pipe 218 through the connecting pipe 204, enters the water inlet channel 212 and the water inlet area 214 through the water inlet area 214, and then enters the connecting port 216, the water outlet area 215, and the water outlet channel 213 through the water inlet area 214, and enters the water tank 201 through the water outlet pipe 217 for circulation. In conjunction with the spraying of the drill bit 106 by the first nozzle 206 and the second nozzle 209, the temperature of the drill bit 106 can be quickly reduced, the thermal stimulation during the operation and the heat and wear caused by friction can be reduced, the drill bit 106 can be prevented from softening or deforming due to high temperature, and the original sharpness and cutting performance of the drill bit 106 can be maintained, thereby improving the cutting efficiency.
