Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to a miniaturized cranial bone drilling device for neurosurgery. Background Art

[0002] A cranial drill is a high-speed rotating drill bit device that can accurately cut bones while reducing damage to surrounding tissues. It is mainly used in neurosurgical operations and the treatment of brain diseases, especially for making holes in the skull for operations such as brain stereotactic positioning and implanting injection needles, electrodes, cannulas, microdialysis catheters, etc. In addition, it can also be used in various operations such as skull fracture repair, craniotomy, skull reconstruction, skull fixation, cranioplasty, and cerebrospinal fluid drainage;

[0003] During the use of existing miniaturized cranial bone drilling devices for neurosurgery, the cooling mechanism can only spray coolant on one side of the drill bit, resulting in the inability to evenly and effectively reduce the overall temperature of the drill bit during the high-speed rotation and skull drilling process. Since the coolant cannot fully cover all the working surfaces of the drill bit, a part of the drill bit may be accelerated in wear due to overheating, thus affecting the accuracy and safety of the operation.

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

[0017] In the above solution, when the device needs to cool down, the first motor is started. 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. The rotating column drives the drill bit to rotate, so that the drill bit drills into the patient's skull position. At the same time, the spraying component is started. When the drill bit contacts the skull, the spraying component can cool down between the drill bit and the patient's skull, effectively reducing the temperature of the skull, thereby reducing the risk of thermal injury and protecting the tissues and nerves around the skull from damage, improving the safety of the operation. When the monitoring component monitors that the temperature of the drill bit is relatively high, the cooling component is started to cool down the drill bit, preventing the drill bit from excessive wear due to high temperature, ensuring the cutting efficiency and operation effect of the drill bit during the operation, and cooperating with the spraying component can double cool the drill bit and the patient's skull, which can not only extend the service life of the drill bit, improve the drilling accuracy, but also reduce the risk of thermal injury to the patient's skull and improve the operation efficiency.

[0018] When it is necessary to cool down between the drill bit and the patient's skull, the water pump is started, and the coolant in the water tank is extracted through the water delivery 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 the coolant onto the drill body part of the drill bit, effectively dispersing and taking away a large amount of heat generated by friction, preventing the overall overheating of the drill bit, thereby extending the service life of the drill bit. The second nozzle is responsible for spraying the coolant onto the drill tip part of the drill bit, which can quickly reduce the temperature between the drill tip and the skull, reduce the risk of thermal injury, and at the same time maintain the sharpness and cutting efficiency of the drill tip, ensuring the accuracy and safety of the operation, and can also reduce the smoke and splashes generated due to high temperature, reducing the risk of infection during the operation.

[0019] When it is necessary to cool the drill bit, the water pump is started, and the coolant in the water tank is extracted through the water delivery 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 communication 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. Through the action of the coolant circulation, the temperature of the drill bit can be quickly reduced, reducing the thermal stimulation during the operation and the heat and wear generated by friction, preventing the drill bit from softening or deforming due to high temperature, and maintaining the original sharpness and cutting performance of the drill bit, thereby improving the cutting efficiency.

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

[0041] Such as Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a miniaturized cranial bone drilling device for neurosurgery, which includes two vertical plates 101. A horizontal plate 102 is slidably connected between the two vertical plates 101. The bottom end of the horizontal plate 102 is fixedly connected with two fixing blocks 103. The bottom ends of the two fixing blocks 103 are fixedly connected with the same circular block 104. The bottom end of the circular block 104 is rotatably connected with a rotating column 105. The bottom end of the rotating column 105 is fixedly connected with a drill bit 106. The bottom end of the horizontal plate 102 is fixedly connected with a fixing frame 107. The middle part of the fixing frame 107 is fixedly connected with a first motor 108. The output end of the first motor 108 is fixedly connected with a first gear 109. The outer surface of the rotating column 105 is fixedly connected with a second gear 110. The second gear 110 meshes with the first gear 109. A spraying assembly for spraying the drill bit 106 is arranged on the horizontal plate 102. A cooling assembly for cooling is arranged on the drill bit 106. A monitoring assembly for monitoring the drill bit 106 is arranged on the circular block 104.

[0042] When the device needs to be used, 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. The rotating column 105 drives the drill bit 106 to rotate, so that the drill bit 106 drills into the patient's skull position. At the same time, the spraying assembly is started. When the drill bit 106 contacts the skull, the spraying assembly can cool the area between the drill bit 106 and the patient's skull, effectively reducing the temperature of the skull, thereby reducing the risk of thermal damage and protecting the surrounding tissues and nerves of the skull from damage, improving the safety of the operation. When the monitoring assembly monitors that the temperature of the drill bit 106 is relatively high, the cooling assembly is started to cool the drill bit 106, preventing the drill bit 106 from being excessively worn due to high temperature, ensuring the cutting efficiency and operation effect of the drill bit 106 during the operation, and cooperating with the spraying assembly to double-cool the drill bit 106 and the patient's skull, which can not only extend the service life of the drill bit 106, improve the drilling accuracy, but also reduce the risk of thermal damage to the patient's skull and improve the operation efficiency.

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

[0044] When it is necessary to cool the space between the drill bit 106 and the patient's skull, start the water pump 203, extract the coolant in the water tank 201 through the water delivery pipe 202, the extracted coolant enters the connecting pipe 204 through the water pump 203, enters the first annular pipe 205, the shunt pipes 207 and the second annular pipe 208 through the connecting pipe 204, and is sprayed out through the first nozzles 206 and the second nozzles 209. The first nozzles 206 are responsible for spraying the coolant onto the body part of the drill bit 106, effectively dispersing and carrying away a large amount of heat generated by friction, preventing the overall overheating of the drill bit 106, thereby extending the service life of the drill bit 106. The second nozzles 209 are responsible for spraying the coolant onto the tip part of the drill bit 106, which can quickly reduce the temperature between the drill tip and the skull, reduce the risk of thermal injury, and at the same time maintain the sharpness and cutting efficiency of the drill tip, ensure the accuracy and safety of the operation, and can also reduce the smoke and splashes generated by high temperature, reducing the risk of infection during the operation.

[0045] As Figure 4As shown, the cooling assembly includes a cooling channel 210, which is opened in the middle of the drill bit 106. A baffle 211 is fixedly connected to the bottom end of the rotating column 105. The baffle 211 is arranged in a wavy shape. A communication port 216 is opened at the bottom end of the baffle 211. An inlet channel 212 and an outlet channel 213 are opened in the round block 104 and the rotating column 105. The baffle 211 divides the interior of the cooling channel 210 into an inlet area 214 and an outlet area 215. The inlet area 214 and the outlet area 215 are connected through the communication port 216. The inlet area 214 is connected to the inlet channel 212, and the outlet area 215 is connected to the outlet channel 213. The top end of the outlet channel 213 is fixedly connected to a water outlet pipe 217. One end of the water outlet pipe 217 is fixedly connected to the water tank 201. The top end of the inlet channel 212 is fixedly connected to 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 penetrate through the horizontal plate. A plurality of heat conducting blocks 251 are fixedly connected inside 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 inlet area 214 and the outlet area 215 as curved channels. Through holes 252 are opened in the heat conducting block 251. The other end of the heat conducting block 251 is fixedly connected to an adhesive ring 254 located inside the drill bit 106. The bottom end of the baffle 211 is fixedly connected to an adhesive block 253 located inside the drill bit 106. Both the adhesive ring 254 and the adhesive block 253 are adhesive metals.

[0046] When the drill bit 106 needs to be cooled, the water pump 203 is started, and the coolant in the water tank 201 is extracted through the water delivery pipe 202. The extracted coolant enters the connecting pipe 204 through the water pump 203, 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 communication 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, reducing the heat stimulation during the operation and the heat and wear generated by friction, preventing the drill bit 106 from softening or deforming due to high temperature, and maintaining the original sharpness and cutting performance of the drill bit 106, thereby improving the cutting efficiency. Since the baffle 211 is wavy and the baffle 211 and the heat conduction block 251 set the water inlet area 214 and the water outlet area 215 as curved channels, the coolant will flow in the curved channels, which can make the coolant stay in the curved channels for a longer time. The heat conduction block 251 can transfer the heat of the drill bit 106 to the coolant flowing through the curved channels, making the cooling effect better. If the drill bit 106 breaks or fractures during the drilling process, the fragments of the drill bit 106 will fly 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 the fragments of the drill bit 106, playing a role in preventing the fragments from flying everywhere.

[0047] As Figure 5 shown, the monitoring component includes a rectangular sleeve 219, the rectangular sleeve 219 is fixedly connected to the top end of the round block 104, a heat dissipation cylinder 220 is fixedly connected to the top end of the round block 104, the heat dissipation cylinder 220 penetrates through the bottom end of the rectangular sleeve 219, a plurality of heat dissipation holes 221 are formed in the heat dissipation cylinder 220, a sliding plate 222 is slidably connected to the inner wall of the rectangular sleeve 219, a first spring 223 is fixedly connected between the inner wall of the rectangular sleeve 219 and the sliding plate 222, and a sensor 224 is fixedly connected to the inner wall of the rectangular sleeve 219.

[0048] When the temperature of the drill bit 106 needs to be monitored, when the temperature of the drill bit 106 is relatively high, the temperature of the drill bit 106 is transmitted to the inside of the heat dissipation cylinder 220 through the rotating column 105 and the drill bit 106, and the heat enters the rectangular sleeve 219 through the heat dissipation holes 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 started to cool down the drill bit 106, avoiding damage to the skull and surrounding tissues caused by the over-high temperature of the drill bit 106.

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

[0050] By providing the sealing plates 225 and the rotating rods 226, rotating the rotating rods 226 can drive the sealing plates 225 to seal or open the water inlet channel 212 and the water outlet channel 213, which is convenient for the cooling assembly to cool the drill bit 106 when the temperature of the drill bit 106 is relatively high.

[0051] As Figure 7 shown, a U-shaped shell 227 is fixedly connected to the outer surface of the round block 104. One ends of the two rotating rods 226 are rotatably connected to the inner wall of the U-shaped shell 227. Third gears 228 are fixedly connected to the outer surfaces of the two rotating rods 226. A rack plate 229 is slidably connected to the inner wall of the U-shaped shell 227. A pull block 230 is fixedly connected to one side of the rack plate 229. The rack plate 229 slidably penetrates through one end of the U-shaped shell 227. First magnets 231 are symmetrically fixedly connected to the upper and lower sides of the rack plate 229, and second magnets 232 and third magnets 233 are fixedly connected to the inner wall of the U-shaped shell 227.

[0052] When the temperature of the drill bit 106 is relatively high and the water inlet channel 212 and the water outlet channel 213 need to be opened, pull the pull block 230. The pull block 230 drives the rack plate 229 to move outward in the U-shaped shell 227. The rack plate 229 drives the two third gears 228 to rotate simultaneously. When the first magnet 231 slides close to the first spring 223, the rack plate 229 is restricted by the attracting action of the first spring 223, and the sealing plate 225 rotates from the horizontal state to the vertical state, opening the water inlet channel 212 and the water outlet channel 213. When the first magnet 231 approaches the second magnet 232, the sealing plate 225 rotates from the vertical state to the horizontal state, closing the water inlet channel 212 and the water outlet channel 213.

[0053] As Figure 8 shown, lifting grooves 234 are formed in both of the vertical plates 101. The cross plate 102 is slidably connected to the inner walls of the two lifting grooves 234. An L-shaped plate 235 is fixedly connected to the top end of the left vertical plate 101. A second motor 236 is fixedly connected to the inner side of the L-shaped plate 235. The output end of the second motor 236 is fixedly connected to a threaded rod 237. The threaded rod 237 rotatably penetrates through the upper end of the left vertical plate 101. The cross plate 102 is threadedly connected to the threaded rod 237. A limiting rod 238 is fixedly connected to the inner wall of the right vertical plate 101. The cross 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 Figure 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 Figure 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, compressing the second spring 244. The rectangular block 243 drives the connecting plate 246 to slide, and the connecting plate 246 drives the bolt 247 to leave the slot 248. Subsequently, rotate the vertical plate 101 to adjust the angle of the drill bit 106. When adjusted to the appropriate position, release the handle 245, and the second spring 244 rebounds. The rectangular block 243 drives the connecting plate 246 to slide, and the connecting plate 246 drives the bolt 247 to insert into the slot 248 to limit the vertical plate 101 and prevent the vertical plate 101 from rotating randomly.

[0059] As Figure 8 and Figure 10 shown, T-shaped sliders 249 are symmetrically and fixedly connected to the front and rear of the horizontal plate 102, and T-shaped sliding grooves 250 that cooperate with the T-shaped sliders 249 are formed on the vertical plate 101.

[0060] By providing the T-shaped sliders 249 and the T-shaped sliding grooves 250, when the horizontal plate 102 slides on the vertical plate 101, the horizontal plate 102 can drive the T-shaped sliders 249 to slide in the T-shaped sliding grooves 250. The T-shaped sliding grooves 250 can play a role in limiting and guiding the T-shaped sliders 249 and the horizontal plate 102, and can also improve the stability of the horizontal plate 102 during the sliding process.

[0061] The working process 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 within the rectangular housing 242, compressing the second spring 244. The rectangular block 243 drives the connecting plate 246 to slide, and the connecting plate 246 drives the bolt 247 to leave the slot 248. Pull the vertical plate 101 to rotate the two vertical plates 101 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 drilling the patient's skull, release the handle 245. The second spring 244 rebounds, the rectangular block 243 drives the connecting plate 246 to slide, and the connecting plate 246 drives the bolt 247 to insert into the slot 248 to restrict the vertical plate 101 and prevent the vertical plate 101 from rotating randomly. Subsequently, start the second motor 236. 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 limiting rod 238. The horizontal plate 102 drives the round block 104, the rotating column 105, and the drill bit 106 to move to adjust the height of the drill bit 106. When the drill bit 106 is adjusted to the appropriate height, start 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. The rotating column 105 drives the drill bit 106 to rotate, causing the drill bit 106 to drill into the patient's skull position. At the same time, start the water pump 203 to extract the coolant in the water tank 201 through the water delivery 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 sprayed out through the first nozzle 206 and the second nozzle 209. The first nozzle 206 is responsible for spraying the coolant onto the drill body part of the drill bit 106, effectively dispersing and carrying away a large amount of heat generated by friction, preventing the overall overheating of the drill bit 106, and thus extending the service life of the drill bit 106. The second nozzle 209 is responsible for spraying the coolant onto the drill tip part 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 relatively high, the temperature of the drill bit 106 is transferred to the inside of the heat dissipation cylinder 220 through the rotating column 105 and the drill bit 106. The heat enters the rectangular sleeve 219 through the heat dissipation holes 221, causing the air inside the rectangular sleeve 219 to expand and push the sliding plate 222 to move upward. The first spring 223 is compressed. When the sliding plate 222 contacts the sensor 224, it pulls the pulling block 230, and the pulling block 230 drives the rack plate 229 to move outward in the U-shaped housing 227. The rack plate 229 drives the two third gears 228 to rotate simultaneously. When the first magnet 231 slides close to the first spring 223, through the attracting action of the first spring 223, the rack plate 229 is restricted. The sealing plate 225 rotates from the horizontal state to the vertical state, opening the water inlet channel 212 and the water outlet channel 213. The coolant in the water tank 201 is pumped through the water pump 203. The pumped 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 pipe 218, and then enters the communication 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. Cooperating with the spraying of the first spray head 206 and the second spray head 209 on the drill bit 106, the temperature of the drill bit 106 can be rapidly reduced, reducing the heat stimulation during the operation and the heat and wear generated by friction, preventing the drill bit 106 from softening or deforming due to high temperature, and maintaining the original sharpness and cutting performance of the drill bit 106, thereby improving the cutting efficiency.
