DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0027] Reference Figure 1-4A neurosurgery positioner comprises a head support arc plate 1 and a positioning adjustment component 3. The bottom surface of the head support arc plate 1 is provided with a positioning adjustment component 3. One side of the head support arc plate 1 is connected with a neck support arc plate 2. Gear boxes 9 are provided at both ends of the head support arc plate 1. A first gear 6 and a second gear 7 meshing with each other are provided inside the gear box 9. A U-shaped gear shaft arm 8 is penetrated at the center position of the first gear 6 and the second gear 7. The U-shaped gear shaft arm 8 of the first gear 6 is connected to the end of the head support arc plate 1. The U-shaped gear shaft arm 8 of the second gear 7 is connected with a limiting arc plate 4. When the whole device is actually used, it is mainly used to position the patient's head during or after surgery. When used during surgery, it is mainly used to position the patient's head during neurosurgery. , prevent the patient's head from shifting. When used after surgery, the patient's head is positioned after surgery to prevent repeated shaking from pulling the wound and maintain the stability of the head. In actual use, the patient's neck is against the neck support arc plate 2, and the head is prevented from being at the position of the head support arc plate 1. The patient's head is supported by the head support arc plate 1, and the neck support arc plate 2 keeps the neck in contact with it to prevent the neck from being subjected to excessive force. Then the limiting arc plate 4 is rotated to fit the side of the head. By applying force to the limiting arc plate 4, the first gear 6 and the second gear 7 rotate to realize the rotation of the limiting arc plate 4. By setting the first gear 6 and the second gear 7 for driving, positioning after rotation at any angle can be achieved. The stability is high, the rotation angle can be flexibly adjusted, and the adaptability to the head clamping is increased.

[0028] When the whole device is actually installed and adjusted for use, it is mainly installed on the surface of one end of the hospital bed or the operating bed through the positioning and adjustment component 3. The specific structure is that the positioning and adjustment component 3 includes a linear telescopic plate 302 and an L-shaped telescopic plate 303. The L-shaped telescopic plate 303 and the linear telescopic plate 302 are directly provided with an L-shaped adjustment plate 301, and the two ends of the L-shaped adjustment plate 301 are respectively slidably located inside the linear telescopic plate 302 and inside the L-shaped telescopic plate 303. The top surface of the linear telescopic plate 302 is bolted to the bottom surface of the head support arc plate 1. By adjusting the sliding distance between the L-shaped telescopic plate 303 and the L-shaped adjustment plate 301, the adjacent L-shaped telescopic plates 303 are adapted to the width of the hospital bed, so that the L-shaped telescopic plates 301 can be adjusted. The inner side of the end not sleeved with the L-shaped adjustment plate 301 abuts against the outer side of the bed to achieve the width adaptation with the bed surface. The height of the head support arc plate 1 is adjusted by sliding the linear telescopic plate 302 and the L-shaped adjustment plate 301 up and down. After adjustment, since the linear telescopic plate 302, the L-shaped telescopic plate 303 and the L-shaped adjustment plate 301 are all provided with adjustment holes 304 on the surface, and the spacing between adjacent adjustment holes 304 is the same, and the adjustment holes 304 are penetrated with positioning pins 305, the linear telescopic plate 302, the L-shaped adjustment arc plate and the L-shaped telescopic plate 303 are inserted into the positioning pins 305 through the overlapping positions of the adjustment holes 304 on the surface after adjustment, so as to be positioned and prevented from falling off.

[0029] The other limiting structures of the entire device are as follows: the inner wall surface of the limiting arc plate 4 is evenly distributed with anti-slip strips 5 to increase the fit and protection with the head; the two ends of the U-shaped gear shaft arm 8 are movably penetrated with the two ends of the gear box 9 surface, so that the limiting arc plate 4 can be flipped and adjusted; the minimum force for the relative sliding of the first gear 6 and the second gear 7 is 2-3 times the sum of the weights of the limiting arc plate 4 and the U-shaped gear shaft arm 8, so that the limiting arc plate 4 remains stable after adjusting the angle, and will not drive the second gear 7 to rotate due to its own gravity, thereby improving stability; the neck support arc plate 2 is tangent to the head support arc plate 1 at the connection position; the outer edges of the neck support arc plate 2 and the head support arc plate 1 are both rounded to increase the comfort during connection and use, maintain the smoothness of the connection position, and facilitate stable and comfortable support for the neck and head; the length of the limiting arc plate 4 is the same as that of the head support arc plate 1, and the side of the head support arc plate 1 completely overlaps with the side of the neck support arc plate 2, so as to keep the size of the limiting arc plate 4 and the head support arc plate 1 compatible and maintain equal coverage. Specific embodiment 2:

[0031] Reference Figure 1-4 In actual use, in order to increase the stability of the installation of the positioning and adjustment component 3 and the bed, a bolt hole can be selected on the surface of the end of the L-shaped telescopic plate 303 that is not sleeved with the L-shaped adjustment plate 301 according to the actual stability requirements. During installation, the bolt is inserted along the bolt hole until it is bolted to the side of the bed for positioning to increase stability. Specific embodiment three:

[0033] Reference Figure 1-4 When the entire device is actually used, the gear box 9 between the limit arc plate 4 and the head support arc plate 1 can be replaced with a multi-axis support arm for driving, such as directly using a damping shaft to connect the limit arc plate 4 and the head support arc plate 1. When using the damping shaft for angle positioning, it is necessary to ensure that the damping force is greater than the gravity of the limit arc plate 4 to prevent self-rotation after adjustment and maintain stability. Generally, the above-mentioned gear box 9 is used for driving, which has high stability.

[0034] In summary: the present application adopts a head support arc plate 1 in conjunction with a neck support arc plate 2 to support the patient's head and neck, and connects the limiting arc plate 4 through a gear box 9 to clamp and limit the two sides of the patient's head, thereby realizing the positioning of the patient's head during surgery or after surgery on the hospital bed, and preventing the patient's head from shaking. At the same time, by providing arc support for the head and neck, the patient's comfort is increased, and the structural principles that conform to ergonomics are met to achieve positioning of the head, with a simple structure and easy operation. The present application adopts a positioning adjustment component 3 added to the bottom of the head support arc plate 1 for installation on the hospital bed, so that the entire device can be directly installed on the hospital bed through the telescopic adjustment of the positioning adjustment component 3, and adapted to the size of the hospital bed, and the vertical height of the head support arc plate 1 can be adjusted through the positioning adjustment component 3, which is convenient for adjusting the height of the head under different conditions of neurosurgery, and has strong adaptability to installation scenarios and is easy to install and adjust.
