Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a head position protection device for patients after osteotomy. Background Technology

[0002] Decompressive craniectomy is used in various central nervous system diseases such as traumatic brain injury, cerebrovascular disease, and brain tumors, and has become a routine surgical procedure in neurosurgery. It can effectively reduce intracranial pressure and save lives. Postoperative care is also crucial, and maintaining pressure on the surgical area where the craniectomy is performed is an important aspect of postoperative care. The craniectomy incision is located in the area between the patient's forehead and ear. In clinical practice, often only "pressure-free" labels are marked on the surgical dressing, and pressure is prevented by positioning the patient's head in a specific position, without actually using protective equipment that avoids or resists pressure.

[0003] When patients lie in bed, their surgical area is often touched and compressed due to unconscious head movements or when medical staff turn them over for nursing procedures. If this is not corrected in time, it can lead to increased intracranial pressure, infection, and necrosis of the surgical area, significantly impacting postoperative recovery. Current nursing care is ineffective in protecting the head area after bone flap surgery and also increases the workload for medical staff. Therefore, we propose a head positioning protection device for postoperative bone flap surgery to address these issues. Utility Model Content

[0017] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides an embodiment of a head positioning protection device for patients after osteotomy, comprising a base 1, on which a first telescopic adjustment rod 2 is fixedly mounted. The base 1 is T-shaped, and its length and width can be adjusted according to actual application to ensure the stability of the device and prevent tipping. A movable component 3 is provided on the outer side of the first telescopic adjustment rod 2 to adjust the height of the first telescopic adjustment rod 2 according to the patient's needs, improving the applicability of the device. A limit component 4 is provided between the movable component 3 and the first telescopic adjustment rod 2. The movable component 3 includes a rotating shaft 30. 1. Support frame 302, second telescopic adjusting rod 303, support plate 304, baffle 305, elastic strap 306 and protective cover 307. A rotating shaft 301 is provided on the outer side of the first telescopic adjusting rod 2. A support frame 302 is provided on the outer side of the rotating shaft 301. A second telescopic adjusting rod 303 is provided on the outer side of the support frame 302. A support plate 304 is provided on the inner side of the second telescopic adjusting rod 303. A baffle 305 is provided on the upper side of the support plate 304. An elastic strap 306 is provided on the left side of the second telescopic adjusting rod 303. A protective cover 307 is provided on the right side of the support plate 304. This device, through the design of the movable component 3 and the limiting component 4, solves the problem that existing nursing care cannot provide effective protection, thus failing to protect the bone flap area during head surgery and increasing the workload of medical staff.

[0019] Furthermore, a fixing block 401 is fixedly connected to the outer side of the first telescopic adjustment rod 2. A movable groove 402 is provided inside the fixing block 401. A linkage gear 403 is rotatably connected inside the movable groove 402. The left end of the linkage gear 403 is fixedly connected to the rotating shaft 301. A pull rod 404 is movably connected to the top of the fixing block 401. The top of the pull rod 404 is spherical. A limit block 405 is fixedly connected to the lower end of the pull rod 404. The gap between the limit block 405 and the linkage gear 403 is matched. A return spring 406 is movably sleeved on the outer side of the pull rod 404. The two ends of the return spring 406 abut against the limit block 405 and the inner wall of the movable groove 402, respectively. Figure 3 As shown, this structure is used to pull the lever 404 upwards, causing the limiting block 405 to disengage from the gap of the linkage gear 403, compressing the return spring 406, causing the return spring 406 to deform, and releasing the lock on the linkage gear 403. This allows the patient to rotate the linkage gear 403 within the support plate 304 via the rotating shaft 301 to adjust to a comfortable angle. After adjustment, the lever 404 is released, and under the elastic action of the return spring 406, the limiting block 405 is reinserted into the gap of the linkage gear 403, locking the linkage gear 403.

[0020] Furthermore, the right end of the rotating shaft 301 is rotatably connected to the first telescopic adjusting rod 2, and the other end of the rotating shaft 301 is fixedly connected to the support frame 302. The second telescopic adjusting rod 303 is movably sleeved on the surface of the support frame 302. The outer side of the support plate 304 is fixedly connected to the inner wall of the second telescopic adjusting rod 303. The bottom of the baffle 305 is fixedly connected to the support plate 304. The right end of the elastic band 306 is connected to the support plate 304, and the left side of the protective cover 307 is connected to the support plate 304. Figure 2 As shown, this structure is used to place the patient's head inside the support plate 304 and then pull the elastic band 306 to fix it, so that the surgical bone flap area is placed inside the protective cover 307. When the patient is lying in bed and unconsciously turns his head, or when medical staff turn the patient over for nursing care, the rotating shaft 301 is rotated to adjust the patient's head posture and improve the patient's comfort.

[0021] Furthermore, a protective pad 5 is fixedly connected to the inner wall of the support plate 304, and ventilation holes 6 are provided on the surfaces of both the support plate 304 and the protective cover 307. Figure 2 As shown, this structure is used to protect the patient's head through the protective pad 5, avoiding direct contact with the support plate 304 and preventing pressure on the patient, while improving the patient's comfort. The ventilation holes 6 facilitate internal ventilation and heat dissipation.

[0022] Furthermore, a first protrusion 7 is fixedly connected to the end of the linkage gear 403, and a second protrusion 8 is fixedly connected at equal intervals to the inner wall of the movable groove 402. The first protrusion 7 and the second protrusion 8 are made of elastic material. Figure 4 As shown, this structure is used to make the first protrusion 7 and the second protrusion 8 press against each other when the linkage gear 403 rotates in the movable groove 402, so that the linkage gear 403 can rotate stably and uniformly, avoiding sudden excessive rotation amplitude, which could cause secondary injury to the patient.

[0023] Furthermore, a fixing groove 9 is provided on the left side surface of the fixing block 401, and an observation window is fixedly installed inside the fixing groove 9. Figure 3 As shown, this structure is used to facilitate the alignment of the limiting block 405 with the gap at the linkage gear 403 through the observation window at the fixed slot 9, thereby improving the convenience of the device.

[0024] Furthermore, the baffle 305 is made of an elastic material, and the thickness of the support plate 304 is three times that of the protective cover 307. For example... Figure 2As shown, this structure is used to place the patient's head inside the support plate 304 by opening the baffle 305 outward, and slowly releasing the baffle 305 so that it fits against the patient's cheek to fix the patient's head, thereby increasing the contact area and better driving the support plate 304 to rotate as a whole. The thickness difference between the support plate 304 and the protective cover 307 prevents the head surgical area from contacting other objects, ensuring that the surgical area will not be touched or pressured.

[0025] Working principle: When using, such as Figure 1 As shown, first place the base 1 flat on the headboard, then adjust the height of the first telescopic adjustment rod 2 as needed, such as... Figure 2 As shown, adjust the second telescopic adjustment rod 303 and the support frame 302 to a suitable distance and fix them firmly. Then, open the baffle 305 outward so that the patient's head is placed inside the support plate 304. Slowly loosen the baffle 305 so that it fits against the patient's cheek. Then, pull the elastic band 306 to fix it, so that the surgical bone flap area is placed inside the protective cover 307. When it is necessary to turn the patient over or adjust the patient's head position, such as... Figure 3 and Figure 4 As shown, pulling the lever 404 upwards causes the limiting block 405 to disengage from the gap of the linkage gear 403, compressing the return spring 406 and causing it to deform. This releases the lock on the linkage gear 403, allowing the patient to rotate the linkage gear 403 within the support plate 304 via the rotating shaft 301. Simultaneously, the patient's family can hold the support frame 302 to assist in rotation. As the linkage gear 403 rotates within the movable groove 402, the first protrusion 7 and the second protrusion 8 press against each other, creating a small frictional force on the rotation of the linkage gear 403, enabling it to rotate stably and uniformly. After adjusting to a comfortable angle, through the observation window at the fixed groove 9, align the limiting block 405 with the gap of the linkage gear 403, release the lever 404, and under the elastic action of the return spring 406, reinsert the limiting block 405 into the gap of the linkage gear 403, locking the linkage gear 403. This is the complete working principle of this utility model.
