Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a skull drill for neurosurgery. Background Technology

[0002] In neurosurgery, craniotomy is generally performed for cerebrovascular diseases, brain tumors, or space-occupying lesions. The craniotomy usually begins by using a scalpel to make a U-shaped incision at the affected site, followed by drilling a hole in the skull with a craniotomy instrument to facilitate subsequent surgery.

[0003] A skull drill is a medical device mainly used for neurosurgery and the treatment of brain diseases. The function of a skull drill is to create a hole in the skull to perform stereotactic brain positioning and implant injection needles, electrodes, cannulas, microdialysis catheters, and other procedures.

[0004] For example, Chinese patent CN113520514A discloses an improved craniotomy drill for neurosurgery. This drill uses a motor to drive the drill to create an opening in the skull, and transmits command signals via a signal receiver, enabling remote control of the drill bit through a controller. Existing craniotomy drills have poor multi-angle adjustment capabilities for the drill bit and lack precision in locating the lesion site. Their purely mechanical mechanisms cannot avoid the rigidity of mechanically driven operations, leading to problems such as dura mater tears, brain tissue damage, and compressive injuries from traditional rigid supports. They also cannot buffer the vibration of the drill gun and are not adaptable to different head shapes. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a craniotomy drill for neurosurgery to solve the problems of existing craniotomy drills which have poor multi-angle adjustment of the drill bit and poor accuracy in locating the lesion site; purely mechanical mechanism, which cannot avoid the problem of rigid operation driven by mechanical drive, resulting in problems such as dura mater tearing, brain tissue damage, and compression damage caused by traditional rigid stents; and cannot buffer the vibration of the craniotomy drill gun; and cannot adapt to different head shapes.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A craniotomy drill for neurosurgery includes a support frame. A cross arm is fixedly connected to one top end of the support frame. A drive motor is fixedly connected to the top of the cross arm. The output shaft of the drive motor is connected to a rotating shaft. A craniotomy drill arm is fixedly connected to the rotating shaft. A control console is mounted on one end of the support frame. A hydraulic cylinder is inserted into the craniotomy drill arm. An angle adjustment component is fixedly connected to the output end of the hydraulic cylinder. The angle adjustment component is used to adjust the direction of the craniotomy drill. The angle adjustment component is connected to the hydraulic cylinder. An auxiliary positioning component is connected to the angle adjustment component. A vacuum adsorption component is connected to the auxiliary positioning component.

[0008] Optionally, the angle adjustment assembly includes a first slide rail fixedly connected to the output end of the hydraulic cylinder, a second slide rail slidably connected to the bottom of the first slide rail, the second slide rail being an arc-shaped slide rail, an electric actuator fixedly connected to one end of the top of the first slide rail, and the output end of the electric actuator being connected to the second slide rail.

[0009] Optionally, a sliding frame is slidably connected to the bottom of the second slide rail, the top of the sliding frame is equipped with a self-locking component, a skull drill is fixedly connected to the bottom of the sliding frame, and an auxiliary handle is fixedly connected to one end of the skull drill.

[0010] Optionally, a drive rod is inserted into the bottom of the skull drill, and a cross-shaped groove is formed at the bottom of the drive rod. An image fixing tube is rotatably connected to the surface of the drive rod, and multiple cameras are fixedly connected to the bottom of the image fixing tube. Multiple notches are opened at the bottom opening of the image fixing tube.

[0011] Optionally, a skull drill is inserted into the bottom of the image fixation tube, and a cross-shaped locking block is fixedly connected to the top of the skull drill. The cross-shaped locking block is the same size as the cross-shaped slot at the bottom of the drive rod above. A first spring is also rotatably connected to the top of the skull drill, and the top of the first spring is rotatably connected to the bottom of the drive rod.

[0012] Optionally, the auxiliary positioning component includes an annular fixing frame fixedly connected to the bottom surface of the drill gun. Multiple support arms are fixedly connected to the end of the annular fixing frame. The ends of the multiple support arms are provided with circular holes. Insertion rods are inserted into the ends of the multiple support arms. The bottom of the insertion rods is fixedly connected to a support frame.

[0013] Optionally, a second spring is sleeved on the surface of a plurality of the plug rods, the top of the second spring is fixedly connected to the bottom of the support arm, the bottom of the second spring is fixedly connected to the top of the support frame, and an alloy main frame is fixedly connected to one end of the support frame, the alloy main frame being configured as an annular shape.

[0014] Optionally, the support frame is fixedly connected to the surface of the support frame, multiple miniature telescopic rods are inserted into the top of the alloy main frame, the output ends of the multiple miniature telescopic rods are fixedly connected to miniature tree branch frames, and multiple pressure sensors are fixedly connected to the top of the alloy main frame.

[0015] Optionally, the vacuum adsorption assembly includes a silicone pad inserted into a micro-branch frame. The bottom of the silicone pad is made of frosted material, and the inner wall of the silicone pad has multiple holes. Multiple flexible threaded tubes are inserted into the inside of the silicone pad, and the bottom of the silicone pad has multiple lower absorption ports.

[0016] Optionally, one end of each of the multiple flexible threaded tubes is fixedly connected to a hose, one end of the hose is fixedly connected to a recovery tube, one end of the recovery tube is fixedly connected to a collection box, the collection box is fixedly connected to the top of the cross arm, and one end of the collection box is equipped with a negative pressure air box.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up an angle adjustment component, the angle of the craniotomy gun can be adjusted using the first and second slide rails. This allows the surgeon to flexibly adjust the drill angle along the sagittal and coronal planes, adapting to the curved shape of the skull, avoiding areas with dense blood vessels and nerves, and achieving precise positioning of the lesion site during craniotomy. This reduces the risk of accidental brain tissue injury due to angle deviation. The use of the cross-shaped locking block ensures that when the drill penetrates the skull, the loss of resistance triggers the spring to rebound, causing the drill to instantly disengage from the drive rod and stop rotating. This avoids the problem of rigid operation driven by mechanical drive and reduces the probability of dura mater tearing or brain tissue damage. When mechanically driven, the surgeon can use the auxiliary handle for command-style operation, improving operational accuracy, enhancing the ability to respond to emergencies, increasing safety, and reducing the fatigue of medical staff. This allows medical staff to focus more on surgical strategy and precise operation control.

[0019] By combining auxiliary positioning components and vacuum adsorption components, the ring positioning frame is fixedly connected to the skull drill gun, achieving an alloy main frame that elastically fits the head surface, adapting to different head shapes and avoiding the compressive damage of traditional rigid supports. A miniature branch frame inserted into the silicone pad forms a mesh support structure, dispersing local pressure and preventing excessive mechanical stress from deforming the silicone pad, causing the ring positioning frame to tilt and resulting in a lack of stress at the bottom. The silicone pad material cushions the vibration of the skull drill gun, reducing the risk of instrument displacement due to vibration during drilling. Furthermore, the frosted material at the bottom of the silicone pad increases friction with the scalp, preventing slippage. Combined with the negative pressure generated by the negative pressure fan, the opening at the bottom of the silicone pad tightly adheres to the scalp, improving stability. The skull near the drill bit is absorbed through the soft threaded tubes on the inner wall of the silicone pad, ensuring a clean working area. Additionally, the airflow generated by the negative pressure also cools the drill bit area, reducing the risk of lesions and damage to brain tissue. Attached Figure Description

[0041] like Figures 1 to 12As shown, an embodiment of the present invention provides a craniotomy drill for neurosurgery, including a support 1, a cross arm 2 fixedly connected to one top end of the support 1, a drive motor 10 fixedly connected to the top of the cross arm 2, an output shaft of the drive motor 10 connected to a rotating shaft 3, a craniotomy drill arm 4 fixedly connected to the rotating shaft 3, a control console 5 mounted on one end of the support 1, a hydraulic cylinder 9 inserted inside the craniotomy drill arm 4, an angle adjustment component 6 fixedly connected to the output end of the hydraulic cylinder 9, the angle adjustment component 6 being used to adjust the direction of the craniotomy; an auxiliary positioning component 7, used for auxiliary positioning during craniotomy, the auxiliary positioning component 7 being connected to the angle adjustment component 6; and a vacuum adsorption component 8, used for adsorbing the head surface, the vacuum adsorption component 8 being connected to the auxiliary positioning component 7.

[0042] As an implementation method in this embodiment, such as Figures 3 to 7As shown, the angle adjustment assembly 6 includes a first slide rail 61 fixedly connected to the output end of the hydraulic cylinder 9. A second slide rail 62 is slidably connected to the bottom of the first slide rail 61. The second slide rail 62 is an arc-shaped slide rail. An electric actuator 63 is fixedly connected to one end of the top of the first slide rail 61. The output end of the electric actuator 63 is connected to the second slide rail 62. A sliding frame 64 is slidably connected to the bottom of the second slide rail 62. The top of the sliding frame 64 has a self-locking component. Specifically, a locking nut is installed on the sliding frame 64. Tightening the locking nut in one direction locks the sliding frame 64 to the second slide rail 62. Tightening the locking nut in the other direction allows the sliding frame 64 to slide relative to the second slide rail 62. A skull drill 65 is fixedly connected to the bottom of the sliding frame 64. An auxiliary handle 66 is fixedly connected to one end of the skull drill 65. A drive rod 67 is inserted into the bottom of the skull drill 65. A cross-shaped groove is formed at the bottom of the drive rod 67. An image fixing tube 68 is rotatably connected to the surface of the drive rod 67. Multiple cameras are fixedly connected to the bottom of the image fixing tube 68. Multiple notches are opened at the bottom of the image fixing tube 68. A skull drill head 69 is inserted into the bottom of the image fixing tube 68. A cross-shaped locking block 610 is fixedly connected to the top of the skull drill head 69. The cross-shaped locking block 610 is the same size as the cross-shaped groove at the bottom of the drive rod 67. One end of a first spring 611 is connected to the top of the skull drill head 69. The other end of the first spring 611 is connected to the bottom of the drive rod 67. When the hydraulic cylinder 9 moves the first slide rail 61, which is fixedly connected to the output end, to the vicinity of the patient's head, the hydraulic cylinder 9 stops. Then, the electric actuator 63, fixedly connected to the top end of the first slide rail 61, begins to drive, causing the second slide rail 62 to slide on the first slide rail 61. Once the second slide rail 62 reaches the designated position, the electric actuator 63 stops. Then, the sliding frame 64 moves on the second slide rail 62. Once the skull drill 65, fixedly connected to the bottom of the sliding frame 64, moves to a suitable angle, it stops moving and the sliding frame 64 is locked. Then, medical personnel pull the auxiliary handle 66 to move the skull drill 65 towards the surface of the skull, and then the drill head 69... The skull makes contact and then moves upward in the image fixation tube 68. As the drill head 69 moves upward, the cross-shaped locking block 610 fixedly connected to the top of the drill head 69 moves upward synchronously. At the same time, as the drill head 69 moves upward, the first spring 611, which is rotatably connected to the drill head 69, begins to retract between the drive rods 67. Then, the cross-shaped locking block 610 is inserted into the cross-shaped slot at the bottom of the drive rod 67 to achieve alignment. Meanwhile, multiple cameras installed at the bottom of the image fixation tube 68 capture images in real time and feed them back to the screen on the control console 5, so that medical staff can monitor changes in the head at any time, and detect any bleeding or damage.

[0043] As an implementation method in this embodiment, such as Figures 4 to 10As shown, the auxiliary positioning component 7 includes an annular fixing frame 71 fixedly connected to the bottom surface of the drill gun 65. Multiple support arms 72 are fixedly connected to the ends of the annular fixing frame 71. Circular holes are opened at the ends of the multiple support arms 72, and insertion rods 73 are inserted into the ends of the multiple support arms 72. A support frame 75 is fixedly connected to the bottom of the insertion rods 73. Second springs 74 are sleeved on the surfaces of the multiple insertion rods 73. The tops of the second springs 74 are fixedly connected to the bottoms of the support arms 72, and the bottoms of the second springs 74 are fixedly connected to the tops of the support frame 75. An alloy main frame 77 is fixedly connected to the bottom of one end of the support frame 75. The alloy main frame 77 is annular. Mounting parts 76 are fixedly connected to the surface of the support frame 75. Multiple miniature telescopic rods 78 are inserted into the top of the alloy main frame 77. Miniature tree branch frames 79 are fixedly connected to the output ends of the multiple miniature telescopic rods 78. Multiple pressure sensors 710 are fixedly connected to the top of the alloy main frame 77. When the silicone pad 81 inserted at the bottom of the alloy main frame 77 first contacts the scalp surface, the pressure sensor 710 senses the upward force transmitted by the silicone pad 81 to the alloy main frame 77. Subsequently, the alloy main frame 77 drives multiple support frames 75 fixedly connected to the mounting component 76 to move upward. As the multiple support frames 75 move, the plug rods 73 fixedly connected to the ends of the multiple support frames 75 move upward. At the same time, the second spring 74 sleeved on the surface of the plug rod 73 begins to contract at the bottom of the support arm 72 as the support frame 75 moves upward, buffering the upward force on the alloy main frame 77 and reducing mechanical damage to the head. Then, the pressure sensor 710 adjusts the output length of the miniature telescopic rod 78 according to the pressure on different parts, and adjusts the force on the miniature tree branch frame 79 in the silicone pad 81.

[0044] As an implementation method in this embodiment, such as Figures 8 to 12As shown, the vacuum adsorption assembly 8 includes a silicone pad 81 inserted into the micro-branch frame 79. The bottom of the silicone pad 81 is made of frosted material. Multiple holes are opened in the inner wall of the silicone pad 81. Multiple flexible threaded tubes 82 are inserted into the inside of the silicone pad 81. Multiple lower absorption ports 87 are opened at the bottom of the silicone pad 81. One end of the multiple flexible threaded tubes 82 is connected to a flexible hose 83, and the other end is exposed. One end of the flexible hose 83 is connected to one end of a recovery tube 84. The other end of the recovery tube 84 is connected to a collection box 85. The collection box 85 is fixedly connected to the top of the cross arm 2. A negative pressure air box 86 is installed at one end of the collection box 85. When the silicone pad 81 contacts the head, and the pressure sensor 710 senses the pressure on different parts, the miniature telescopic rod 78 is adjusted to ensure the silicone pad 81 fits tightly against the scalp surface, reducing mechanical stress damage. Then, the skull drill 65 drives the skull drill head 69 to rotate. At this time, the negative pressure fan 86, fixedly connected to one end of the collection box 85, begins to operate, generating negative pressure airflow that is transmitted through the recovery pipe 84 to the multi-way hose 83. Simultaneously, the multi-way hose 83 transmits the negative pressure airflow to the flexible threaded tube 82, which then applies suction through multiple openings on the inner wall of the silicone pad 81. Absorption is applied to the area of ​​the skull drill 69. Simultaneously, negative pressure airflow acts on multiple lower absorption ports 87 at the bottom of the silicone pad 81. The multiple lower absorption ports 87 apply suction to the scalp surface, increasing the tightness. Then, the soft threaded tube 82 transports the absorbed skull fragments through the recovery tube 84 to the collection box 85. At this time, the recovery of skull fragments keeps the working surface clean, providing a favorable working environment for the surgery and reducing the probability of emergencies. At the same time, it reduces friction between the skull and the skull drill 69, reduces heat emission, and the negative pressure suction simultaneously absorbs heat from the surface of the skull drill 69, reducing heat damage to the head.

[0045] The working principle of the technical solution provided by this invention is as follows:

[0046] When using this device, first move the support 1 to the side of the operating table, then start the drive motor 10 through the control console 5 to adjust the rotation angle of the rotating shaft 3, thereby adjusting the rotation angle of the skull drilling robotic arm 4, and then drive the hydraulic cylinder 9.

[0047] When the hydraulic cylinder 9 is driven, the angle adjustment component 6 starts to operate. First, the hydraulic cylinder 9 moves the first slide rail 61, which is fixedly connected to the output end, to the vicinity of the patient's head. Then, the hydraulic cylinder 9 stops. Subsequently, the electric push rod 63, which is fixedly connected to the top end of the first slide rail 61, starts to drive, causing the second slide rail 62 to slide on the first slide rail 61. After the second slide rail 62 moves to the designated position, the electric push rod 63 stops. Then, the sliding frame 64 moves on the second slide rail 62. After the skull drill 65, which is fixedly connected to the bottom of the sliding frame 64, moves to the appropriate angle, it stops moving and the sliding frame 64 is locked. Then, the medical staff pulls the auxiliary handle 66 to drive the skull drill 65 towards the surface of the skull. The drill bit 69 moves and then contacts the skull. It then moves upward in the image fixation tube 68. As the drill bit 69 moves upward, the cross-shaped locking block 610 fixedly connected to the top of the drill bit 69 moves upward synchronously. At the same time, as the drill bit 69 moves upward, the first spring 611, which is rotatably connected to the drill bit 69, begins to retract between the drive rods 67. Then, the cross-shaped locking block 610 is inserted into the cross-shaped slot at the bottom of the drive rod 67 to achieve alignment. Meanwhile, multiple cameras installed at the bottom of the image fixation tube 68 capture images in real time and feed them back to the screen on the control console 5, so that medical staff can monitor changes in the head at any time, and detect any bleeding or damage.

[0048] As the drill bit 69 contacts the skull, the auxiliary positioning component 7 begins to operate. First, the silicone pad 81 inserted at the bottom of the alloy main frame 77 contacts the scalp surface. Then, the pressure sensor 710 senses the upward force transmitted from the silicone pad 81 to the alloy main frame 77. Subsequently, the alloy main frame 77 drives multiple support frames 75 fixedly connected to the mounting component 76 to move upward. As the multiple support frames 75 move, the plug rods 73 fixedly connected to the ends of the multiple support frames 75 move upward. At the same time, the second spring 74 sleeved on the surface of the plug rod 73 begins to contract at the bottom of the support arm 72 as the support frame 75 moves upward, buffering the upward force on the alloy main frame 77 and reducing mechanical damage to the head. Then, the pressure sensor 710 adjusts the output length of the miniature telescopic rod 78 according to the pressure on different parts, adjusting the force on the miniature tree branch frame 79 in the silicone pad 81.

[0049] When the silicone pad 81 contacts the head, and the pressure sensor 710 senses the pressure on different parts, the miniature telescopic rod 78 is adjusted to ensure the silicone pad 81 fits tightly against the scalp surface, reducing mechanical stress damage. Then, the skull drill 65 drives the skull drill head 69 to rotate. At this time, the negative pressure fan 86, fixedly connected to one end of the collection box 85, begins to operate, generating negative pressure airflow that is transmitted through the recovery pipe 84 to the multi-way hose 83. Simultaneously, the multi-way hose 83 transmits the negative pressure airflow to the flexible threaded tube 82, which then applies suction through multiple openings on the inner wall of the silicone pad 81. Absorption is applied to the area of ​​the skull drill 69. Simultaneously, negative pressure airflow acts on multiple lower absorption ports 87 at the bottom of the silicone pad 81. The multiple lower absorption ports 87 apply suction to the scalp surface, increasing the tightness. Then, the soft threaded tube 82 transports the absorbed skull fragments through the recovery tube 84 to the collection box 85. At this time, the recovery of skull fragments keeps the working surface clean, providing a favorable working environment for the surgery and reducing the probability of emergencies. At the same time, it reduces friction between the skull and the skull drill 69, reduces heat emission, and the negative pressure suction simultaneously absorbs heat from the surface of the skull drill 69, reducing heat damage to the head.
