Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical technology, and in particular to a temporary skull fixation device. Background Technology
[0002] When a patient undergoing brain surgery or experiencing high intracranial pressure due to intracranial hemorrhage, medical staff often need to perform a surgical procedure to remove part of the skull. After the brain surgery is completed or the patient's intracranial pressure drops to normal levels, the removed part of the skull is then placed back in its original position to facilitate the patient's recovery.
[0003] Most existing temporary skull fixators are generally used to fix the skull using T-hooks. While T-hooks are well-suited for fixing planar skulls, they are often unsuitable for fixing and compressing curved skulls due to their shape, making it difficult to fully insert and compress, or to adjust and remove them after insertion. This results in limitations for some temporary skull fixators when used on curved skulls, leading to unreliability in their use. Utility Model Content
[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a temporary skull fixator, comprising an auxiliary adjustment ring, an auxiliary guide plate rotatably mounted on the inner side of the auxiliary adjustment ring, a power guide column slidably mounted on the inner side of the auxiliary guide plate, a temporary fixing rod fixedly mounted on the surface of the power guide column, and a temporary fixing rod slidably mounted on the inner side of the auxiliary adjustment ring, wherein the temporary fixing rod is in an L-shape.
[0006] Preferably, an auxiliary push plate is bonded to the surface of the power guide column, and the surface of the auxiliary push plate is provided with a resistance-increasing groove.
[0007] Preferably, the surface of the power guide column is slidably adjustable with an elastic component, and the two ends of the elastic component are respectively abutted against and installed on the opposite sides of the auxiliary push plate and the auxiliary guide disc.
[0008] Preferably, the surface of the temporary fixing rod is provided with anti-slip grooves.
[0009] Preferably, the surface of the auxiliary adjustment ring is provided with a limiting groove, and the upper limit groove of the auxiliary adjustment ring is I-shaped.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] (1) After the skull is repositioned, the operator controls the auxiliary push plate to drive the temporary fixation rod on the power guide column to extend outward. At this time, the auxiliary push plate is rotated 90 degrees to reset. Therefore, the L-shaped temporary fixation rod can be removed from the skull suture. This method not only effectively ensures the ease of pressing and adjusting when fixing the skull, but also ensures the reliability of fixing and adjusting the skull block of the arc-shaped bone suture. It improves the disadvantage that the traditional T-type temporary fixation rod can only be applied to the straight skull suture and cannot be used to put in and take out the arc-shaped skull suture. This greatly improves the convenience of using the fixation rod for the arc-shaped skull, reduces the limitation of the T-type temporary fixation rod for the arc-shaped skull, and improves the ease of using the fixation rod for temporary auxiliary fixation and limiting.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0018] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0021] Please see Figure 1-3 This utility model provides a technical solution: a temporary skull fixator, including an auxiliary adjustment ring 1, an auxiliary guide plate 2 rotatably mounted on the inner side of the auxiliary adjustment ring 1, a power guide column 3 slidably mounted on the inner side of the auxiliary guide plate 2, an auxiliary push plate 4 bonded to the surface of the power guide column 3, and a resistance-increasing groove 5 formed on the surface of the auxiliary push plate 4. The function of the auxiliary push plate 4 is to assist medical staff in controlling the power guide column 3 to descend and adjust inside the auxiliary guide plate 2. Furthermore, the resistance-increasing groove 5 on the auxiliary push plate 4 can increase the frictional resistance between the auxiliary push plate 4 and the medical staff's fingers, thereby making it easier for the medical staff to control the auxiliary push plate 4 to drive the power guide column 3 to rotate and adjust between the auxiliary guide plate 2 and the auxiliary adjustment ring 1, thus ensuring the stability of the auxiliary push plate 4 during rotational adjustment.
[0022] Furthermore, the surface of the power guide column 3 is slidably adjustable with an elastic component 6. The two ends of the elastic component 6 are respectively abutted and installed on the opposite sides of the auxiliary push plate 4 and the auxiliary guide disk 2. The function of the elastic component 6 is to provide support for the extension between the power guide column 3 and the auxiliary guide disk 2. When the power guide column 3 is compressed and deformed by the auxiliary push plate 4, it is no longer subject to external pressure. The elastic component 6 will adjust itself through its own compression deformation to move the auxiliary push plate 4 away from the auxiliary adjustment ring 1 for support.
[0023] Furthermore, a limiting groove 7 is provided on the surface of the auxiliary adjustment ring 1. The upper limit groove 7 of the auxiliary adjustment ring 1 is in the shape of an I-shape. The I-shape of the upper limit groove 7 of the auxiliary adjustment ring 1 can ensure that the medical staff's hands have a good limiting effect when holding the object.
[0024] Furthermore, a temporary fixation rod 8 is fixedly installed on the surface of the power guide column 3. The surface of the temporary fixation rod 8 is slidably installed on the inner side of the auxiliary adjustment ring 1. The surface of the temporary fixation rod 8 is provided with an anti-slip groove 9. The temporary fixation rod 8 is L-shaped. When it is necessary to support the cranial sutures of the fixator, the medical staff only needs to control the auxiliary push plate 4 to squeeze the power guide column 3 down to the inside of the auxiliary guide plate 2. At this time, the power guide column 3 drives the temporary fixation rod 8 to extend outward on the inner side of the auxiliary adjustment ring 1. Then, the medical staff controls the horizontal surface of the L-shaped temporary fixation rod 8 to enter the interior of the cranial sutures. Then, the medical staff controls the auxiliary push plate 4 to rotate the temporary fixation rod 8 on the power guide column 3 by 90 degrees, so that the L-shaped temporary fixation rod 8 forms a barb on the inner side of the skull. At this time, the temporary fixation rod 8 hooks only the main skull of the head and presses it down, and then detaches. The fallen portion of the skull can increase friction through the anti-slip groove 9 on the back of the hook of the temporary fixation rod 8, pressing the free bone downwards and aligning the two bones. After the skull is repositioned, the operator controls the auxiliary push plate 4 to extend the temporary fixation rod 8 on the power guide column 3. At this time, the auxiliary push plate 4 is rotated 90 degrees to reset, so the L-shaped temporary fixation rod 8 can be removed from the cranial suture. This method not only effectively ensures the ease of pressing and adjusting the skull during fixation, but also ensures the reliability of the fixator for fixing and adjusting curved skulls. It improves the disadvantage of the traditional T-shaped temporary fixation rod 8, which can only be used in straight cranial sutures and is inconvenient to enter and exit in curved cranial sutures. This greatly improves the convenience of using the fixator for curved skulls, reduces the limitation of using the T-shaped temporary fixation rod 8 for curved skulls, and improves the ease of using the fixator for temporary auxiliary fixation and limiting.
[0025] Working principle: A temporary cranial fixator is used to support the cranial sutures. When this fixator is needed, the medical staff controls the auxiliary push plate 4 to compress the power guide column 3, which descends inside the auxiliary guide disc 2 to the inside of the auxiliary adjustment ring 1. At this time, the power guide column 3 drives the temporary fixation rod 8 to extend outwards from the inside of the auxiliary adjustment ring 1. Then, the medical staff controls the transverse surface of the L-shaped temporary fixation rod 8 to pass through the cranial sutures and enter its interior. Finally, the medical staff controls the auxiliary push plate 4 to rotate the temporary fixation rod 8 on the power guide column 3 by 90 degrees, thus causing the L-shaped... The temporary fixation rod 8 forms a barb on the inner side of the skull. At this time, the temporary fixation rod 8 only hooks the main part of the skull and presses it down. The free part of the skull can increase the friction through the anti-slip groove 9 on the back of the hook of the temporary fixation rod 8, pressing the free bone down and aligning the two bones. After the skull is repositioned, the operator controls the auxiliary push plate 4 to drive the temporary fixation rod 8 on the power guide column 3 to extend outward. At this time, the auxiliary push plate 4 is rotated 90 degrees to reposition. Therefore, the L-shaped temporary fixation rod 8 can be removed from the cranial suture.
[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
