Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, in particular to a head cooling device used in neurosurgery. Background Art

[0002] Neurosurgery is an important branch of surgery, which mainly studies the human nervous system, including the damage of the brain, spinal cord and peripheral nervous system and its subsidiary structures, the diagnosis, treatment and prevention of diseases. In terms of disease treatment, neurosurgery covers a wide range. For brain diseases, such as brain tumors, doctors remove tumor tissue through surgery to minimize damage to normal brain tissue; for cerebral hemorrhage, the hematoma should be removed in time to reduce intracranial pressure and avoid further damage to brain tissue. In the field of spinal cord diseases, spinal cord injuries and spinal cord tumors can be treated by surgically repairing the damaged spinal cord or removing tumors. For peripheral nerve diseases, such as sciatic nerve There are also corresponding treatments for pain, carpal tunnel syndrome, etc. The technical means of neurosurgery are advanced and constantly developing. In addition to traditional craniotomy and spinal surgery, there are also minimally invasive techniques such as neuroendoscopy and stereotactic surgery, which reduce surgical trauma and improve patients' recovery speed and quality of life. Neurosurgeons must not only have superb surgical skills, but also have comprehensive neuroscience knowledge to protect the health of patients' nervous systems. Brain nerve cells are extremely sensitive to temperature changes. The increase in head temperature during surgery will accelerate the metabolic rate of nerve cells, resulting in a sharp increase in oxygen consumption. During surgery, blood supply to the brain may be limited.

The output shaft of the servo motor 3021 passes through the cooling box 2 to the inner cavity of the second installation cavity 301 and is fixedly connected to the side of the first turntable 302.

[0050] A semicircular ring 304 is provided on the outside of the first turntable 302, and two connecting rods 303 are fixedly connected between the semicircular ring 304 and the first turntable 302. A second turntable 305 is fixedly connected to the side of the first turntable 302, and a locking rod 306 is fixedly connected to the side of the second turntable 305. A first supporting block 307 is fixedly connected to the inner wall of the second mounting cavity 301, and a driving rod 308 is rotatably connected to the middle of the first supporting block 307. A third turntable 309 is fixedly sleeved on the outside of the driving rod 308, and a number of sliding grooves 310 are opened on the side of the third turntable 309. A fourth turntable 311 is also fixedly sleeved on the outside of the driving rod 308. A plurality of U-shaped grooves 312 are provided on the side of the disk 311, and the engaging rod 306 is slidably engaged with the slide groove 310 and the U-shaped groove 312, and the semicircular ring 304 is slidably engaged with the U-shaped groove 312. The output shaft of the servo motor 3021 drives the first turntable 302 and the second turntable 305 to rotate, while making the semicircular ring 304 and the engaging rod 306 rotate synchronously, and the engaging rod 306 is intermittently slidably engaged with the slide groove 310 and the U-shaped groove 312, and the semicircular ring 304 is intermittently slidably engaged with the U-shaped groove 312, which can enable the third turntable 309 to drive the driving rod 308 and the first ice crusher 314 at the bottom of the driving rod 308 to rotate intermittently.

[0051] A rotating gear 313 is fixedly sleeved on the outer side of the driving rod 308, and a plurality of first ice crushing knives 314 are fixedly connected to the bottom of the rotating gear 313. A second supporting block 315 is fixedly connected to the inner wall of the second installation cavity 301. A driving rod 316 is rotatably connected to the middle part of the second supporting block 315. A driving gear 317 is fixedly connected to the outer side of the driving rod 316. A plurality of second ice crushing knives 318 are fixedly connected to the bottom of the driving rod 316. The rotating gear 313 is meshed with the driving gear 317 for transmission. Two water flow holes 324 are provided on the inner wall of the second installation cavity 301. A filter plate 319 is commonly provided on the outer side of the two water flow holes 324. The filter plate 319 is fixedly connected to the inner wall of the second installation cavity 301. A plurality of filter holes 320 are provided on the outer side of the filter plate 319. The second installation cavity 301 is connected to the cooling pipe 20 The second mounting cavity 301 is connected to the outer wall of the second mounting cavity 301, and a torsion spring 322 is sleeved on the outer side of the mounting cavity 301. Both ends of the mounting cavity 301 are rotatably connected to a one-way plate 323. One end of the torsion spring 322 is fixedly connected to the inner wall of the second mounting cavity 301, and the other end of the torsion spring 322 is fixedly connected to the side of the one-way plate 323. When the driving rod 308 rotates, the rotating gear 313 engages with the driving rod 316 for transmission, so that the driving rod 316 drives the second ice crushing blade 318 to rotate. The second ice crushing blade 318 and the first ice crushing blade 314 rotate in opposite directions at the same time, accelerating the crushing of ice cubes. The ice water is mixed with the ice smoothie and then flows to the cooling pipe 201, which can absorb heat more efficiently. When this low-temperature mixture flows to the cooling pipe, it can quickly take away the heat around the patient's head, thereby achieving rapid cooling.

[0052] It should be noted that a water pump is provided on the side of the cooling tube 201. When the ice cubes inside the second installation cavity 301 are crushed, they will be sucked into the cooling tube 201 through the filter plate 319. The one-way plate 323, the torsion spring 322 and the turn pin 321 are combined into a "one-way valve" to prevent the crushed ice from flowing back into the first installation cavity 205. The bottom plate of the inner cavity of the second installation cavity 301 is set as an inclined plate to facilitate the crushed ice to flow better to the filter plate 319.

[0053] The specific implementation of this embodiment is as follows: by setting up an ice crushing assembly 30, before the operation, ice cubes are placed in the first installation cavity 205, and ice water is poured into the second installation cavity 301. When the temperature of the patient's head is too high, the cylinder 208 is started first and then the servo motor 3021 is started. The cylinder 208 drives the contact plate 207 to move, and the ice cubes fall from the inside of the through hole 206 to the inside of the second installation cavity 301. The output shaft of the servo motor 3021 drives the first turntable 302 and the second turntable 305 to rotate. The semicircular ring 304 rotates synchronously with the engaging rod 306, and the engaging rod 306 intermittently slides and engages with the sliding groove 310 and the U-shaped groove 312. The semicircular ring 304 intermittently slides and engages with the U-shaped groove 312. When the engaging rod 306 engages with the sliding groove 310 and the U-shaped groove 312, it can drive the fourth rotating disk 311 to rotate intermittently. The arrangement of the semicircular ring 304 is to avoid the fourth rotating disk 311 from rotating after the engaging rod 306 slides and engages with the sliding groove 310 and the U-shaped groove 312, thereby ensuring the lower When the first ice-crushing blade 314 stops rotating, the ice cubes that have not been completely crushed will adjust their positions under the action of gravity or other external forces. When the first ice-crushing blade 314 rotates the next time, these ice cubes can be better crushed. When the driving rod 308 rotates, the rotating gear 313 engages with the driving rod 316, so that the driving rod 316 drives the second ice-crushing blade 318 to rotate. The second ice-crushing blade 318 and the first ice-crushing blade 314 rotate in opposite directions at the same time, accelerating the crushing of ice cubes. The ice water and ice smoothie are mixed and then flow to the cooling pipe 201 to reduce the temperature around the patient's head. When this low-temperature mixture flows to the cooling pipe 201, it can quickly take away the heat around the patient's head, achieving rapid cooling, and timely responding to the situation where the patient's head temperature is too high, thereby preventing further damage to the brain caused by high temperature.
