Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical device technology, specifically referring to a neck brace for post-neurosurgery care. Background Technology
[0002] Neurosurgery is a highly complex and risky medical procedure. Patients often experience problems such as limited head movement and weakened neck muscles after surgery. If the neck lacks effective support, abnormal neck posture can affect the healing of the surgical site and even increase the risk of postoperative complications. Therefore, a neck brace is needed to fix and support the neck after surgery. Existing neck braces often concentrate the stress points on the chest and spine areas, making it difficult to distribute the stress across multiple points. Long-term use can easily lead to excessive local stress, causing pain and strain in the chest, spine, and surrounding muscles. These discomfort symptoms are more pronounced for patients with long postoperative recovery periods who need to wear neck braces for extended periods, seriously affecting their wearing experience and recovery comfort. In conclusion, there is an urgent need to develop a nursing neck brace that can achieve multi-point force distribution and is easy to operate, in order to improve the quality of postoperative neck care, reduce patient discomfort, and promote smooth patient recovery. Summary of the Invention
[0003] This invention overcomes the shortcomings of existing technologies and provides a neck brace for post-neurosurgery care. When the height of the chin support is adjusted by the telescopic rod, the linkage pawl and ratchet disengage, and the elastic potential energy of the coil spring drives the transmission gear ring, transmission gear and driven gear to rotate, so that the shoulder support fits precisely to both sides of the patient's shoulders and the back support fits to both sides of the back. This realizes the distribution and support of the weight of the head and neck to multiple parts of the chest, shoulders and back, effectively reducing the single point of force and pain.
[0004] The technical solution adopted by this invention is as follows: This solution provides a cervical support for post-neurosurgery care, including a chest support bracket, a chin support bracket, and a cervical support plate. The chest support bracket is used to conform to the front of the patient's chest to provide initial support. A mounting frame is symmetrically fixed on the chest support bracket. The chin support bracket is hinged in the mounting frame and is used to conform to the bottom of the patient's chin to support the weight of the head. The cervical support plate is rotatably connected to the outer wall of the mounting frame. A telescopic rod is rotatably provided on the chest support bracket. The other end of the telescopic rod is fixedly connected to the bottom wall of the chin support bracket, driving the chin support bracket to rotate up and down. A shoulder support bracket is rotatably connected in the mounting frame. The shoulder support bracket is in transmission cooperation with the chin support bracket. A back support bracket is rotatably connected in the mounting frame. The back support bracket is in transmission cooperation with the shoulder support bracket, realizing the diversion of the weight of the head and neck to the shoulders and back, reducing the single-point stress burden.
[0005] Furthermore, a drive shaft is fixedly installed on the outer wall of the mandibular support. The drive shaft is rotatably connected to the mounting frame. A pawl is hinged on the circumferential wall of the drive shaft. The drive shaft rotates synchronously with the rotation of the mandibular support, and the rotation of the back support is driven or released by driving the pawl.
[0006] Furthermore, a spring is fixedly installed on the inner wall of the pawl, and the other end of the spring is fixedly connected to the circumferential wall of the transmission shaft to provide elastic restoring force for the pawl, so that the pawl can stably engage or disengage with the ratchet teeth in the transmission gear ring during the rotation of the transmission shaft.
[0007] Furthermore, a transmission gear ring is rotatably connected inside the mounting bracket, and a ratchet is fixedly provided inside the transmission gear ring. The ratchet moves in contact with the pawl, and the rotation of the transmission gear ring is restricted or released by moving in contact with or disengaging from the pawl.
[0008] Furthermore, a transmission gear is fixedly installed on the inner wall of the shoulder bracket, and the transmission gear meshes with the transmission gear ring to provide rotational power for the back bracket.
[0009] Furthermore, a coil spring is nested inside the transmission gear, and both ends of the coil spring are fixedly connected to the mounting bracket and the transmission gear, respectively, to provide elastic power for the rotation of the transmission gear.
[0010] Furthermore, a driven gear is fixedly installed on the inner wall of the back bracket, and the driven gear meshes with the transmission gear to drive the back bracket to rotate.
[0011] The beneficial effects achieved by the present invention using the above structure are as follows: (1) When the height of the mandibular support is adjusted by the telescopic rod, the mandibular support is flipped upward. At the same time, after the pawl and the ratchet are disengaged, the elastic potential energy of the coil spring is used to drive the transmission gear ring to rotate, so that the shoulder support can accurately fit the patient's shoulders. The flipped and fitted shoulder support directly transmits part of the weight of the head and neck to the shoulders on both sides, forming a diversion support. The force is distributed to the front support through the shoulders on both sides, so that the force point supporting the head is not limited to the upper chest, which can reduce the phenomenon of large single-point force burden and pain. (2) After the coil spring drives the transmission gear to rotate, the transmission gear meshes with the driven gear. The driven gear drives the back support to fit against the patient's back on both sides. The back support bears the weight transmitted from the head, neck and shoulders and distributes it evenly to the entire back area. Through the coordinated force of the back muscles, the pressure is evenly distributed to the back muscles, avoiding local stress concentration in the spine. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0016] Example 1: Please refer to Figures 1-4This embodiment provides a cervical support for post-neurosurgery care, including a chest support bracket 1, a chin support 2, and a cervical support plate 3. A mounting frame 4 is symmetrically fixed on the chest support bracket 1. A transmission gear ring 5 is rotatably connected within the mounting frame 4, and a ratchet 6 is fixedly installed within the transmission gear ring 5. The chin support 2 is hinged within the mounting frame 4. A transmission shaft 7 is fixedly installed on the outer wall of the chin support 2 and rotatably connected within the mounting frame 4. A pawl 8 is hinged to the circumferential wall of the transmission shaft 7, and the ratchet 6 movably abuts against the pawl 8. A spring 9 is fixedly installed on the inner wall of the pawl 8, and the other end of the spring 9 is fixedly connected to the circumferential wall of the transmission shaft 7. One end of the cervical support plate 3 is rotatably connected to the outer wall of the mounting frame 4, and the other end of the cervical support plate 3 is connected to another mounting frame. 4. The outer wall is engaged. A telescopic rod 10 is rotatably provided on the chest support bracket 1. The telescopic rod 10 includes a bushing and a threaded rod. The bushing is rotatably connected to the chest support bracket 1. One end of the threaded rod is threaded into the bushing, and the other end of the threaded rod is fixedly connected to the chin support 2. A shoulder support 11 is rotatably connected inside the mounting frame 4. A transmission gear 12 is fixedly provided on the inner wall of the shoulder support 11. The transmission gear 12 meshes with the transmission gear ring 5. A coil spring 13 is nested inside the transmission gear 12. Both ends of the coil spring 13 are fixedly connected to the mounting frame 4 and the transmission gear 12, respectively. A back support 14 is rotatably connected inside the mounting frame 4. A driven gear 15 is fixedly provided on the inner wall of the back support 14. The driven gear 15 meshes with the transmission gear 12. In this embodiment, the nurse first places the chest support 1 against the front of the patient's chest. Then, the neck support 3 is flipped inward from the back of the neck so that the arc-shaped surface of the neck support 3 fits against the skin on the back of the neck. The free end of the neck support 3 is then flipped towards the mounting bracket 4 until it engages, thus fixing the neck support 3. Based on the patient's chin height and the required support angle for the neck after surgery, the nurse rotates the bushing of the telescopic rod 10, pushing the chin support 2 upward until it fully fits the bottom of the patient's chin. At this point, part of the head's weight is transferred to the chest support 1. During the upward flipping of the chin support 2, the transmission shaft 7, which is fixedly connected to the chin support 2, rotates synchronously. The pawl 8 hinged on the transmission shaft 7 rotates with the transmission shaft 7, and its free end gradually disengages from the ratchet 6 on the inner side of the transmission gear ring 5. The rotation restriction of the transmission gear ring 5 is released, and the coil spring 13, which was previously compressed due to the contact of the pawl 8, begins to release its elasticity. Potential energy drives the transmission gear 12 to rotate around its own axis. The transmission gear 12 meshes with the driven gear 15 of the back support 14. When the transmission gear 12 rotates, it drives the driven gear 15 to rotate in the opposite direction. As the transmission gear 12 rotates, the shoulder supports 11 on both sides flip towards the patient's shoulders under the drive of the transmission gear 12, until the arc surface of the shoulder support 11 is completely in contact with the upper side of the shoulder. At the same time, the back support 14 flips towards the patient's back under the drive of the driven gear 15, until the arc surface of the back support 14 is completely in contact with the upper side of the back. This transfers the weight of the head and neck to the shoulders and back. The force is distributed to the front support through the shoulders and to the rear support through the back, so that the force point supporting the head is not limited to the upper chest and upper spine, which can reduce the phenomenon of large single-point force burden and pain.
[0017] When removing the device, the caregiver rotates the bushing of the telescopic rod 10 in the opposite direction, pushing the chin support 2 downwards. During the downward rotation of the chin support 2, the transmission shaft 7, which is fixedly connected to the chin support 2, rotates synchronously. The pawl 8 hinged on the transmission shaft 7 abuts against the ratchet 6 on the inner side of the transmission gear ring 5. The transmission gear ring 5 rotates synchronously with the transmission shaft 7, driving the transmission gear 12 to rotate in the opposite direction, twisting the coil spring 13, and causing the coil spring 13 to restore elastic potential energy. At the same time, the transmission gear 12 also meshes with the driven gear 15 of the back support 14. When the transmission gear 12 rotates, it will drive the driven gear 15 to rotate. As the transmission gear 12 rotates, the shoulder brackets 11 and back brackets 14 on both sides will flip away from the patient's body. The shoulder brackets 11 and back brackets 14 will completely detach from the patient's body. At this time, the brackets will be reset. Then, the neck brace 3 will be released from the mounting bracket 4. The neck brace 3 will be flipped outward from the back of the neck so that the arc-shaped surface of the neck brace 3 is away from the back of the neck. Then, the chest brace 1 will be removed from the patient's chest. Finally, the entire neck brace will be removed.
[0018] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
