Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an intelligent cranial drill for neurosurgery. Background Art

[0002] A cranial drill is a common medical device in neurosurgery. The cranial drill can drill holes in the patient's skull, which is convenient for medical staff to perform brain stereotactic positioning and inject needles. A common cranial drill usually consists of a drill bit and a drill handle. A spring is embedded between the drill bit and the drill handle. When the drill bit abuts against the skull, the spring connected to the drill bit will be compressed. At this time, the drill bit and the drill handle will engage, and the drill handle will drive the drill bit to rotate. After the hole in the skull is drilled by the drill bit, the drill bit will not be compressed, and the compressed spring will drive the drill bit to reset. At this time, the drill bit will no longer engage with the drill handle, and the drill handle cannot drive the drill bit to rotate. When this kind of cranial drill is actually used, it can indeed drill holes in the patient's skull, but there are still the following deficiencies in its actual use:

[0003] 1. When the existing cranial drill drills holes in the patient's skull, it is easy to cause the bone chips to splash. At this time, medical staff need to use external equipment to drip physiological saline on the drilled part of the patient's skull. Although the physiological saline injected by the external equipment can moisten the bone chips at the drilled part and reduce the probability of bone chip splashing, it is not convenient for the staff to limit the injection pressure of the physiological saline through the external equipment. When the injection pressure of the physiological saline is relatively large, the water splashed by the physiological saline will block the vision of the medical staff, which is not convenient for the medical staff to perform neurosurgery on the patient.

[0004] 2. When the existing cranial drill drills holes in the patient's skull, a lot of heat will be generated at the part where the cranial drill and the drilled hole are located. In order to reduce the heat generated at the part where the cranial drill and the drilled hole are located, medical staff usually adopt the distributed drilling method to drill holes in the patient's skull. Although this drilling method can achieve a good drilling effect on the patient's skull, it reduces the efficiency of skull drilling.

[0005] Therefore, we propose an intelligent cranial drill for neurosurgery. Summary of the Invention

Specific implementation manner

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1: Please refer to Figure 1-3 Figures 5 - 10, and the present invention provides a technical solution:

[0038] An intelligent cranial drill for neurosurgery includes an infusion pump machine 1 and a holding structure 3 connected to the infusion pump machine 1. A drilling structure 7 is detachably connected to the holding structure 3, and further includes:

[0039] A water distribution structure 6 connected to the drilling structure 7. The water distribution structure 6 is detachably connected to the holding structure 3, and the water distribution structure 6 can convey water liquid to the drilling structure 7 to dissipate the heat on the drilling structure 7.

[0040] The water diversion structure 6 includes a transmission column 63 rotatably connected to the holding structure 3. The drilling structure 7 includes a housing structure 72 fixedly connected to the lower part of the transmission column 63. A sliding head 79 is clamped inside the housing structure 72. A drilling blade 74 is fixedly connected to the lower part of the sliding head 79. The number of drilling blades 74 is multiple. Water guiding holes 75 are formed between the fixed parts of the multiple sliding heads 79 and the sliding heads 79. The transmission column 63 can drive the drilling blade 74 through the sliding head 79 to drill holes in the skull.

[0041] During the actual use of this craniotome, the housing structure 72 is the drill handle structure in the existing craniotome, and the drilling blade 74 is the drill bit structure in the existing craniotome. When the housing structure 72 drives the drilling blade 74 to rotate, it can drill holes in the patient's skull.

[0042] A water receiving structure 9 is connected to the housing structure 72. The water receiving structure 9 includes a water receiving pipe 91 fixedly connected to the housing structure 72. A water receiving groove 92 is formed in the housing structure 72 near the water receiving pipe 91. The water receiving groove 92 is used for guiding the physiological saline inside the housing structure 72 to flow inside the water guiding holes 75. A diversion inclined port 97 is formed in the water receiving pipe 91 near the sliding head 79. A collecting shell 94 is fixedly connected to the water receiving pipe 91 near the diversion inclined port 97. A sealing plate 96 is slidably connected to the collecting shell 94. An extrusion rod 95 is fixedly connected to the sealing plate 96. The extrusion rod 95 penetrates through the water receiving pipe 91. A spring plunger 93 is detachably connected to the collecting shell 94. The output end of the spring plunger 93 penetrates through the collecting shell 94 and is fixedly connected to the sealing plate 96.

[0043] When the sliding head 79 in this craniotome moves upward, the sliding head 79 can squeeze the extrusion rod 95. At this time, the extrusion rod 95 can convey the sealing plate 96 into the inside of the collecting shell 94, and the spring plunger 93 stores energy for work. At the same time, the inner cavity of the water receiving pipe 91 is communicated with the inner cavity of the housing structure 72. The physiological saline inside the housing structure 72 can be discharged to the patient's skull through the water receiving pipe 91, so as to wet the bone debris on the patient's skull and avoid the bone debris on the patient's skull from splashing. It should be added that the spring plunger 93 proposed in this document is the spring column structure on the existing market and belongs to the scope well-known to those skilled in the art.

[0044] Embodiment 2: Please refer to Figure 1-10 , the present invention provides a technical solution:

[0045] The water diversion structure 6 further includes a clamping groove 67 formed in the inner wall of the transmission column 63. A spring groove 62 is formed in the upper wall of the inner cavity of the clamping groove 67. A connecting spring 64 is fixedly connected inside the spring groove 62.

[0046] The sliding head 79 includes an abutting block 65 fixedly connected to the top surface of the sliding head 79. A transmission block 77 is fixedly connected to the abutting block 65. The transmission block 77 can be embedded inside the clamping groove 67, and at the same time, the upper part of the transmission block 77 abuts against the connecting spring 64.

[0047] A plurality of sliding heads 79 are fixed to each other with the axis of the housing structure 72 as the center. Each drill blade 74 is provided with a diversion hole 76, and the diversion hole 76 communicates with the inner cavity of the water guide hole 75.

[0048] Plug connectors 78 are fixedly connected to the fixed parts of the plurality of drill blades 74. The plug connectors 78 are located at the lower ends of the drill blades 74. A water diversion hole 73 is provided at the part of each drill blade 74 close to the plug connector 78, and the water diversion hole 73 communicates with the inner cavity of the water guide hole 75.

[0049] A limiting groove hole 71 is provided between the drill blade 74 and the sliding head 79. A limiting sliding ring 66 is slidably connected to the limiting groove hole 71, and the limiting sliding ring 66 is fixedly connected to the inner wall of the housing structure 72;

[0050] Before the drill is used, the repulsive force generated by the connecting spring 64 can drive the transmission block 77 to separate from the clamping groove 67. At this time, the transmission column 63 cannot drive the drill blade 74, and it can be realized that when the skull is drilled through, the drill blade 74 stops rotating inside the patient's skull. When the drill is in use, the medical staff abuts the plug connector 78 against the drilling part of the patient's skull. At this time, the plug connector 78 can be squeezed, and the limiting sliding ring 66 can slide inside the limiting groove hole 71. At this time, the transmission block 77 can be inserted into the clamping groove 67. When the transmission column 63 drives the transmission block 77 to rotate, the sliding head 79 can drive the drill blade 74 to rotate, and it can be realized that the drill blade 74 and the housing structure 72 drill the skull;

[0051] Example 3: Please refer to Figure 1-10 , the present invention provides a technical solution:

[0052] When the drill is in use, the water guide hole 75 can drive the physiological saline inside the sliding head 79 and the housing structure 72 to be delivered to the inside of the diversion hole 76. At the same time, the drill blade 74 can drive the plug connector 78 to be inserted into the inside of the skull drill hole. The water diversion holes 73 around the plug connector 78 can discharge the physiological saline to the inside of the skull drill hole, and it can be realized that the drill blade 74 and the housing structure 72 are quickly cooled, and the heat on the drill blade 74 and the housing structure 72 can be prevented from being transferred to the skull drill hole. At the same time, the physiological saline discharged by the plug connector 78 drives the bone slag inside the skull drill hole to be discharged, and the bone slag inside the skull drill hole can be prevented from contacting the dura mater.

[0053] Example 4: Please refer to Figure 1-3 -5-10, the present invention provides a technical solution:

[0055] A water guiding structure 4 is detachably connected to a position on the housing structure 32 close to the controller 31. The water guiding structure 4 includes a water guiding ring 41 fixedly connected to the housing structure 32. A bent ring 43 is fixedly connected to the lower part of the water guiding ring 41. A heat conducting shell 42 is fixedly connected inside the water guiding ring 41. A driving motor 5 is fixedly connected inside the heat conducting shell 42. A sealing strip 44 is fixedly connected to the lower part of the bent ring 43. A fixing ring 45 is detachably connected to the sealing strip 44. A sliding ring 46 is fixedly connected to a position on the water guiding ring 41 close to the fixing ring 45.

[0056] The output end of the driving motor 5 is fixedly connected to a driving column 63. A communication hole 61 is provided at a position on the driving column 63 close to the sliding ring 46. The inner cavity formed by the water guiding ring 41 and the fixing ring 45 communicates with the inner cavity of the outer shell structure 72 through the communication hole 61.

[0057] The water pumping structure 8 includes a protective shell 82 fixedly connected to the housing structure 32. A partition plate 84 is fixedly connected to the middle of the protective shell 82. An output motor 81 is fixedly connected above the partition plate 84 inside the protective shell 82. A gear disk 83 is rotatably connected to a position on the protective shell 82 close to the partition plate 84. A gear column 813 is engaged with the gear disk 83. The gear column 813 is fixedly connected to the output shaft of the output motor 81. A rotating column 812 is fixedly connected to the gear disk 83. A pull rod 85 is sleeved on the rotating column 812. The pull rod 85 penetrates through the partition plate 84. A sealing rubber ring 811 is sleeved at the penetrating position of the pull rod 85 and the partition plate 84. The sealing rubber ring 811 is fixedly connected to the partition plate 84. A pulling piece 86 is fixedly connected to the pull rod 85. A pulling ring 87 is embedded at a position on the protective shell 82 close to the pulling piece 86. A sliding column 814 penetrates through the pulling ring 87. The sliding column 814 is fixedly connected to the pulling piece 86. A columnar end 88 is fixedly connected to the end of the sliding column 814 away from the pulling piece 86. A sealing ring 810 is sleeved on the outer wall of the pulling ring 87. The water suction pipe 23 is fixedly connected to the lower part of the protective shell 82. A water outlet pipe 89 is fixedly connected to the lower part of the protective shell 82. Solenoid valves 815 are connected to both the water outlet pipe 89 and the water suction pipe 23 close to the protective shell 82. The end of the water outlet pipe 89 away from the protective shell 82 is fixedly connected to the water guiding ring 41;

[0058] The infusion pump 1 can convey liquid inside the upper connecting pot 21 and the lower connecting pot 22. The function of the controller 31 in this document is to control the output motor 81 and the transmission motor 5 to work. When this craniotome is actually used, the staff pre-place physiological saline inside the upper connecting pot 21 and the lower connecting pot 22. Subsequently, the output motor 81 drives the tooth column 813 to work. The tooth column 813 can drive the tooth disc 83 to rotate. The tooth disc 83 can pull the pull rod 85 through the rotating column 812, and can realize that the pulling piece 86 drives the pulling ring 87 to move inside the protective shell 82. When the pulling piece 86 gradually approaches the partition plate 84, the solenoid valve 815 on the water outlet pipe 89 works, which can prevent the water outlet pipe 89 from communicating with the inside of the protective shell 82. At the same time, the solenoid valve 815 on the water suction pipe 23 does not work, and the physiological saline inside the water suction pipe 23 will enter the inside of the protective shell 82 under the action of atmospheric pressure. When the pulling piece 86 gradually moves away from the partition plate 84, the pulling piece 86 will abut against the pulling ring 87. At this time, the solenoid valve 815 on the water suction pipe 23 works, and the inner cavity of the water suction pipe 23 is not communicated with the inner cavity of the protective shell 82. At the same time, the solenoid valve 815 on the water outlet pipe 89 does not work, and it can realize that the pulling piece 86 drives the pulling ring 87 to push the physiological saline inside the protective shell 82. At this time, the physiological saline inside the protective shell 82 will enter the inner cavity of the water guide ring 41 through the water outlet pipe 89. Subsequently, the physiological saline inside the inner cavity of the water guide ring 41 will enter the inside of the housing structure 72 through the communication hole 61. When the physiological saline enters the inner cavity of the water guide ring 41, the physiological saline will take away the heat inside the heat conduction shell 42, and can realize the rapid cooling of the transmission motor 5. It should be added that the sealing rubber ring 811 is made of an elastic material.
