Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a neurosurgical arm support. Background Technology

[0002] Neurosurgery is a surgical procedure specifically designed to treat diseases, injuries, or abnormalities related to the nervous system. These surgeries primarily focus on the brain, spinal cord, nerves, and peripheral nerves, often involving complex and delicate procedures. The main goal of neurosurgery is to treat, repair, alleviate, or restore the function of the nervous system through surgical methods. Currently, different neurosurgical procedures have different requirements for the patient's arm posture. For example, spinal surgery requires the patient's upper limb to be kept at a certain angle to avoid compression of the shoulder and arm nerves. Because neurosurgery usually involves delicate procedures, arm stability is very important. In craniocerebral surgery, arm fixation also helps to ensure the balance of the whole body posture. Arm supports need to be able to keep the patient's limb stable for a long time during the operation, preventing displacement due to any external interference, so that the patient can better cooperate with the operation.

[0003] Referring to patent number CN218220538U, an operating room nursing arm support is described as follows: It includes a support plate, with a lifting and rotating assembly at the bottom of the support plate. A fixing assembly is located at the bottom of the lifting and rotating assembly. A first bevel gear, a second bevel gear, a rotating rod, and a turntable are provided to drive a threaded rod to rotate. The threaded rod is threadedly connected to a lifting sleeve. A limiting slider and a limiting groove are provided to restrict the lifting sleeve and prevent the telescopic rod from rotating. Therefore, when the threaded rod rotates, it can drive the lifting sleeve to perform telescopic movement within the connecting base cylinder, thereby adjusting the height of the support plate for convenient patient use.

[0004] However, during the actual implementation process, the applicant discovered the following problems with the patent:

Detailed Implementation

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] As described in the background art, in the specific application of this patent, it can only lift the patient's arm. When it is necessary to lift the patient's arm to a certain tilt angle, it cannot be adjusted, thereby reducing the effectiveness of lifting the patient's arm.

[0033] To solve this technical problem, this utility model provides a neurosurgical arm support, which is applied in neurosurgery.

[0034] For details, please refer to Figures 1-3 A neurosurgical arm support specifically includes a base 1, a support rod 2 fixedly connected to the middle of the upper end of the base 1, a bearing seat 3 provided at the end of the support rod 2 away from the base 1, a first hinge seat 4 fixedly connected to the middle of the lower end of the bearing seat 3, the first hinge seat 4 being rotatably connected to the upper end of the support rod 2, a cavity being provided inside the support rod 2, a rotating mechanism 6 being provided inside the cavity, a connecting component 5 being provided on one side of the support rod 2 at one end of the bearing seat 3, a first frame 7 being fixedly connected to both ends of the upper end of the bearing seat 3, a lifting plate 8 being provided between the upper ends of the two first frames 7, a fixing block 12 being fixedly connected to both sides of the upper ends of the lifting plate 8, a limit mechanism 11 being provided at both ends of the two first frames 7 corresponding to the fixing block 12, and a clamping mechanism 9 being provided at the upper end of the bearing seat 3 at the position between the two first frames 7.

[0035] The present invention provides a neurosurgical arm support. Through the structural design of the connecting component 5 and the rotating mechanism 6, it can be seen that when it is necessary to adjust the angle of the patient's arm support, the angle of the patient's arm support can be adjusted by the cooperation of the connecting component 5 and the rotating mechanism 6, thereby improving the effect of supporting the patient's arm.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Please refer to Figures 1-6 A neurosurgical arm support includes a base 1, a support rod 2 fixedly connected to the middle of the upper end of the base 1, a bearing seat 3 provided at the end of the support rod 2 away from the base 1, a first hinge seat 4 fixedly connected to the middle of the lower end of the bearing seat 3, the first hinge seat 4 being rotatably connected to the upper end of the support rod 2, a cavity being provided inside the support rod 2, a rotating mechanism 6 being provided inside the cavity, a connecting component 5 being provided on one side of the support rod 2 at one end of the bearing seat 3, a first frame 7 being fixedly connected to both ends of the upper end of the bearing seat 3, a lifting plate 8 being provided between the upper ends of the two first frames 7, a fixing block 12 being fixedly connected to both sides of the upper ends of the lifting plate 8, a limit mechanism 11 being provided at both ends of the two first frames 7 corresponding to the fixing block 12, and a clamping mechanism 9 being provided at the upper end of the bearing seat 3 at the position between the two first frames 7.

[0039] Through the above structural design, it can be seen that the base 1 and the support rod 2 can support the bearing seat 3, the two first frames 7 at the upper end of the bearing seat 3 can support the lifting plate 8, the lifting plate 8 can support the patient's arm, the lifting plate 8 can be easily disassembled through the cooperation of the four fixing blocks 12 at the upper end of the lifting plate 8 and the four limiting mechanisms 11, and the clamping mechanism 9 can limit the patient's arm on the lifting plate 8 after the patient places his arm on the lifting plate 8.

[0040] Specifically, the rotating mechanism 6 includes a motor 14, which is fixed at the bottom of the cavity. The output end of the motor 14 is fixedly connected to a first screw 13, and the end of the first screw 13 away from the motor 14 is rotatably connected to the top of the cavity.

[0041] Specifically, the connecting component 5 includes a connecting rod 16, which is located outside the support rod 2. The upper end of the connecting rod 16 is rotatably connected to a third hinge seat 19, which is fixedly connected to one end of the lower end of the bearing seat 3. The lower end of the connecting rod 16 is rotatably connected to a second hinge seat 17, and a connecting block 18 is fixedly connected to the side of the second hinge seat 17 near the support rod 2. A first sliding groove is provided at the position corresponding to the support rod 2 and the connecting block 18. The first sliding groove is connected to the cavity. The connecting block 18 is slidably connected to the first sliding groove. A movable disk 15 is slidably connected inside the cavity. The movable disk 15 is threadedly connected to the first screw 13. The end of the connecting block 18 away from the second hinge seat 17 is fixedly connected to the movable disk 15.

[0042] Through the above structural design, it can be seen that when it is necessary to adjust the tilt angle of the bearing seat 3, the motor 14 inside the cavity can be started. When the motor 14 is started, the output end of the motor 14 drives the first screw 13 to rotate. When the first screw 13 rotates, the first screw 13 can drive the moving disk 15 to move inside the cavity. When the moving disk 15 moves, the moving disk 15 can drive the second hinge seat 17 to move outside the support rod 2 through the connecting block 18. When the second hinge seat 17 moves, the second hinge seat 17 can adjust the tilt angle of the bearing seat 3 through the connecting rod 16 and the third hinge seat 19.

[0043] Specifically, the clamping mechanism 9 includes a second frame 20, the lower end of which is fixedly connected to both sides of the bearing seat 3. A clamping plate 21 is provided on the inner side of the second frame 20. A first slider 22 is fixedly connected to both ends of the clamping plate 21. A third slide groove 23 is provided on both ends of the inner side of the second frame 20. The first slider 22 is slidably connected to the third slide groove 23. A bearing 24 is fixedly connected to the middle of the upper end of the clamping plate 21. A second screw 25 is fixedly connected to the upper end of the bearing 24. The end of the second screw 25 away from the bearing 24 passes through the second frame 20 and extends to the outer side of the upper end of the second frame 20 and is fixedly connected to a handle 26. The second screw 25 is threadedly connected to the second frame 20.

[0044] Through the above structural design, it can be seen that when it is necessary to limit the patient's arm on the support plate 8, the handle 26 can be rotated. When the handle 26 rotates, it can drive the second screw 25 to rotate. Through the connection between the second screw 25 and the second frame 20, when the second screw 25 rotates, the second screw 25 can drive the clamping plate 21 through the bearing 24 to clamp the patient's arm on the support plate 8, thereby limiting the patient's arm on the support plate 8.

[0045] Example 2:

[0046] The neurosurgical armrest provided in Example 1 has been further optimized, specifically, as follows: Figures 7-9 As shown, the limiting mechanism 11 includes a fixing rod 27. One end of the fixing rod 27 is fixedly connected to the first frame 7. The fixing block 12 fixed on the lifting plate 8 is provided with a first slot 10 at the position corresponding to the fixing rod 27 at the same end. The fixing block 12 is inserted and connected to the fixing rod 27 through the first slot 10.

[0047] Furthermore, a second slot 30 is provided at the upper end of the fixing rod 27, on the side of the fixing block 12 away from the first frame 7. A limiting block 28 is slidably connected inside the second slot 30. The upper end of the limiting block 28 extends to the outer side of the upper end of the fixing rod 27. The upper end of the limiting block 28 away from the first frame 7 is inclined. In order to prevent the limiting block 28 from sliding out of the second slot 30, a second slider 29 is fixedly connected to both sides of the limiting block 28 at the end inside the second slot 30. A second sliding groove is provided on both sides inside the second slot 30. The second slider 29 is slidably connected to the second sliding groove. A spring 31 is fixedly connected to the lower end of the limiting block 28. The lower end of the spring 31 is fixedly connected to the bottom inside the second slot 30.

[0048] Through the above structural design, it can be seen that when it is necessary to disassemble the lifting plate 8, the limiting block 28 can be pressed into the second slot 30. When the limiting block 28 is pressed into the second slot 30, the limiting block 28 squeezes the spring 31, thereby allowing the spring 31 to store the squeezing force. After the limiting block 28 is completely pressed into the second slot 30, the limiting of the fixing block 12 can be released, thereby separating the insertion of the first slot 10 and the fixing rod 27, and the lifting plate 8 can be disassembled. After the lifting plate 8 is disassembled, the pressed limiting block 28 can be released, and the spring 31 releases the stored force to push the limiting block 28 to reset. The reset limiting block 28 can wait for the next time to limit the fixing block 12.
