Description

Technical Field

[0001] This invention relates to the field of head support and fixation devices for treatment chairs, specifically a self-adjusting nursing aid device for otolaryngology surgery based on a shared platform. Background Technology

[0002] The shared platform for otolaryngology surgery is an otolaryngology medical service model built on the concept of medical resource sharing. It integrates the human, technical, and equipment resources of different medical institutions to provide patients with higher-quality, more efficient, and more convenient medical services, while also promoting academic exchanges and discipline development in the field of otolaryngology.

[0003] In otolaryngological (ENT) surgery, stable fixation of the patient's head is crucial for ensuring precise procedures. Existing head support and fixation devices are mostly of a single size, making them unsuitable for patients of different ages and head shapes. Furthermore, the fixation structures for the chin, ears, and head are independent, resulting in cumbersome adjustments and a lack of coordinated adjustment. Some devices use excessively hard materials at their contact points, lacking cushioning and protection, which can cause facial discomfort and even impair local blood circulation with prolonged fixation. Additionally, most devices lack personalized parameter storage, requiring readjustment for repeated treatments and reducing efficiency. Moreover, traditional device adjustments rely on manual operation, resulting in insufficient precision to meet the demands of delicate ENT procedures, causing inconvenience for medical staff and potentially affecting treatment outcomes.

[0004] Therefore, we propose a self-adjusting nursing aid for otolaryngology based on a shared platform to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a self-adjusting nursing aid device for otolaryngology based on a shared platform. Addressing the problems of poor adaptability, cumbersome adjustment, lack of personalized storage, insufficient comfort, and low adjustment accuracy of existing head support and fixation devices, this invention improves the adaptability, comfort, and diagnostic and treatment efficiency of the device by setting up a chin fixation and adjustment mechanism, an ear adjustment mechanism, and a head fastening and fixation mechanism, and by leveraging a shared control platform to achieve coordinated adjustment of these three mechanisms.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a self-adjusting nursing aid device for otolaryngology surgery based on a shared platform, comprising a chin fixing and adjusting mechanism, an ear adjusting mechanism, and a head fastening and fixing mechanism. The ear adjusting mechanism is symmetrically installed on both sides of the chin fixing and adjusting mechanism, and the head fastening and fixing mechanism is mounted above the chin fixing and adjusting mechanism. The three are linked and adjusted through a shared control platform. The chin fixing and adjustment mechanism includes a mounting base plate and a middle frame. Two side columns are fixed to the top of the mounting base plate. The middle frame is located in the middle of the chin fixing and adjustment mechanism. A first movable module and a second movable module are symmetrically distributed on both sides of the middle frame. A set of force-adjusting plates is provided inside the middle frame. A guide cylinder is installed on the inner surface of the middle frame. Cylindrical guide grooves are opened on both sides of the outer surface of the force-adjusting plates. The guide cylinder is slidably connected within the cylindrical guide grooves. Trapezoidal distance adjustment controls are opened inside the two side columns. One side of the outer surface of the trapezoidal distance adjustment control contacts an elastic limiting plate, which limits unidirectional movement on the trapezoidal distance adjustment control.

[0007] Preferably, the surface of the mounting base plate is provided with an insertable limiting groove, and the elastic limiting plate is engaged with the insertable limiting groove. The insertable limiting groove is used to limit the function before operation.

[0008] Preferably, the force adjustment plate has cancellation limit return grooves at both ends, the elastic limit plate is located inside one side of the cancellation limit return groove, and the middle frame has an adjustment control chip installed inside. The adjustment control chip is signal-connected to the shared control platform and is used to control the retracting and extending rollers.

[0009] Preferably, a retraction connecting rod is connected to one side of the outer wall of the elastic limiting plate, and a positioning adjustment belt is wound around the outside of the retraction roller. The positioning adjustment belt passes through the adjustment belt moving frame and extends to the ear adjustment mechanism. The adjustment belt moving frame is movably connected to the first movable module and the second movable module through a connecting block to realize the synchronous retraction and adjustment of the positioning adjustment belt.

[0010] Preferably, the first movable module and the second movable module are connected by a force-bearing rod between the movable modules. The force-bearing rod between the movable modules is an elastic telescopic rod structure, which can adaptively adjust the distance between the two modules according to the width of the patient's chin. The inner surface of the force adjustment plate is fitted with a flexible buffer pad, which is made of medical-grade silicone and has an anti-slip texture on its surface.

[0011] Preferably, the ear adjustment mechanism includes an adjustment mounting component, which is detachably connected to the two side columns. The surface of the adjustment mounting component is provided with an angle adjustment groove, which is an arc-shaped structure. A rotating component is slidably connected inside the groove. One side of the rotating component is fixed in position by a limiting component, and the other side is fixedly connected to the ear fixing ring.

[0012] Preferably, the ear fixation ring is a semi-circular structure made of shape memory alloy material, with a sound insulation buffer layer on the inner side. The ear fixation ring is opened and closed by a quick-release buckle. The end of the positioning adjustment band away from the retractable roller is connected to the ear fixation ring. The adjustment mounting component has a storage module inside, which is connected to the adjustment control chip for storing the patient's ear adjustment parameters.

[0013] Preferably, the head fastening and fixing mechanism includes a top fixing strip, the two ends of which are fixedly connected to the top of the middle frame, and a size adjustment component is installed at the bottom of the top fixing strip.

[0014] Preferably, the size adjustment component is an electric telescopic rod structure, with its bottom fixedly connected to the head fixing ring. The head fixing ring has an arc-shaped structure, and a flexible pad is attached to its inner surface. A pressure sensor is installed inside the flexible pad, and the pressure sensor is signal-connected to the adjustment control chip.

[0015] Preferably, the flexible pad is made of memory foam with ventilation holes on its surface, and the flexible pad is detachably connected to the head fixing ring for easy cleaning and replacement.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves coordinated and adaptive operation of chin fixation, ear positioning, and head fixation, fundamentally solving the problems of scattered adjustment and poor adaptability in traditional devices. Once the patient is in position, the adjustment control chip first receives the start command from the shared platform, driving the retractable roller to rotate forward, causing the positioning adjustment belt wrapped around it to retract synchronously. After passing through the adjustment belt moving frame, one end of the positioning adjustment belt is fixedly connected to the ear fixation ring, and the other end is linked to the first and second movable modules via a connecting block. During the retraction process, it not only pulls the ear fixation ring inward but also pushes the two movable modules to move towards each other along the middle frame through the adjustment belt moving frame. The elastic telescopic rod structure between the two modules adapts to the width of the patient's chin. The chin is initially clamped and positioned by a flexible medical silicone cushioning pad on the inner wall of the force adjustment plate. During this process, the guide cylinder on the inner wall of the middle frame slides smoothly along the cylindrical guide grooves on both sides of the force adjustment plate, ensuring the precise movement trajectory of the force adjustment plate. The elastic limiting plates inside the two side columns slide unidirectionally on the trapezoidal distance adjustment control and engage with the insertable limiting groove of the mounting base plate, completing the position locking of the chin fixing mechanism. At the same time, the rotating part of the ear adjustment mechanism slides along the arc angle adjustment groove to the angle suitable for the patient's ear under the pulling force of the positioning adjustment belt, and is locked and fixed by the limiting part. The ear fixing ring made of memory alloy adaptively fits the ear shape, forming a synchronous linkage fixation of the chin and ear, which greatly improves the positioning accuracy and operation efficiency.

[0017] 2. This invention's device, through modular structural design and intelligent feedback adjustment mechanism, completes the entire automated operation from adaptive positioning to precise fixation and parameter storage, combining high comfort and practicality. After the chin fixation mechanism is activated, if position adjustment is needed, the pull-back connecting rod can be pulled through the cancel limit return grooves at both ends of the force adjustment plate, causing the elastic limit plate to disengage from the trapezoidal distance adjustment control and the insertable limit groove. After unlocking, the retractable roller rotates in the opposite direction, the positioning adjustment belt loosens, and the force rod between the moving modules elastically resets, realizing the distance adjustment between the two movable modules until it is adjusted to the appropriate position and then relocked. The ear adjustment mechanism achieves convenient opening and closing of the ear fixation ring through a quick-release buckle, making it easy for patients to wear. The storage module in the adjustment mounting part is connected to the adjustment control chip signal, recording personalized parameters such as the angle of the ear fixation ring and the contraction amount of the positioning adjustment belt in real time. During the next patient treatment, the shared control platform can directly call up the parameters. The device automatically resets each component to its appropriate state via a control chip, eliminating the need for repeated adjustments. The head-locking mechanism's size adjustment mechanism extends and retracts under the control chip's command, moving the head-locking ring up and down until it fits the top of the patient's head. Pressure sensors inside the flexible pad detect the head contact pressure in real time and feed the data back to the control chip. When the pressure reaches a preset threshold, the control chip stops the electric telescopic rod, preventing excessive pressure and discomfort. The memory foam flexible pad has ventilation holes to improve breathability during prolonged use. The flexible pad and head-locking ring are detachable, allowing for easy cleaning after use and ensuring medical safety. Through the coordinated mechanical structure and closed-loop feedback of intelligent signals, the entire device achieves a high degree of harmony between adaptability, comfort, accuracy, and convenience, significantly reducing the workload of medical staff and improving diagnostic and treatment efficiency.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0021] This invention addresses the problems of poor adaptability, cumbersome adjustment operations, lack of personalized parameter storage, insufficient comfort, and low adjustment accuracy of existing ENT surgical head support and fixation devices. Traditional head fixation devices are mostly of a single size, which cannot adapt to the different head shapes and chin widths of different patients. Furthermore, each fixation structure is adjusted independently, resulting in poor coordination, time-consuming operation, and easy to cause pressure discomfort to patients when in contact. The precision of manual adjustment is also difficult to meet the needs of delicate diagnosis and treatment. This invention was developed to address the problems of the prior art by setting up three interconnected components: a chin fixing and adjustment mechanism 100, an ear adjustment mechanism 200, and a head fastening and fixing mechanism 300. Through the adaptive design of the mechanical structure, the application of flexible contact materials, and the function of personalized parameter storage, multi-dimensional coordinated adjustment is achieved.

[0022] Example 1, please refer to Figures 1-8 As shown, the present invention provides a technical solution: a self-adjusting nursing aid device for otolaryngology surgery based on a shared platform, including a chin fixing and adjusting mechanism 100, an ear adjusting mechanism 200, and a head fastening and fixing mechanism 300. The ear adjusting mechanism 200 is symmetrically installed on both sides of the chin fixing and adjusting mechanism 100, and the head fastening and fixing mechanism 300 is mounted above the chin fixing and adjusting mechanism 100. The three are linked and adjusted through a shared control platform. The chin fixing and adjusting mechanism 100 includes a mounting base plate 106 and a middle frame 103. The top of the mounting base plate 106 is fixed with two side columns 108. The middle frame 103 is located in the middle of the chin fixing and adjusting mechanism 100. An adjustment control chip 114 is installed inside the middle frame 103, and the adjustment control chip 114 is signal-connected to the shared control platform.

[0023] In some embodiments, such as Figure 3 , Figure 5 - Figure 6 and Figure 8As shown, a first movable module 101 and a second movable module 102 are symmetrically distributed on both sides of the intermediate frame 103. The first movable module 101 and the second movable module 102 are connected by a force-bearing rod 115 between the movable modules. The force-bearing rod 115 between the movable modules is an elastic telescopic rod structure, which can adaptively adjust the distance between the two modules according to the width of the patient's chin. A set of force-adjusting plates 104 is provided inside the intermediate frame 103. A flexible buffer pad is attached to the inner wall of the force-adjusting plate 104. The flexible buffer pad is made of medical silicone and has an anti-slip texture on the surface. A guide cylinder 105 is installed on the inner wall of the intermediate frame 103. Cylindrical guide grooves 118 are opened on both sides of the outer wall of the force-adjusting plate 104. The guide cylinder 105 is slidably connected in the cylindrical guide grooves 118. Trapezoidal distance adjustment controls 109 are opened inside the two side columns 108. One side of the outer wall is in contact with an elastic limiting plate 110, which limits unidirectional movement on the trapezoidal distance adjustment control 109. The surface of the mounting base plate 106 is provided with an insertable limiting groove 107, and the elastic limiting plate 110 is engaged with the insertable limiting groove 107. Both ends of the force adjustment plate 104 are provided with cancellation limit return grooves 111. The elastic limiting plate 110 is located inside one side of the cancellation limit return groove 111. One side of the outer wall of the elastic limiting plate 110 is connected to a return connecting rod 112. The adjustment control chip 114 is connected to a take-up and release roller 113. A positioning adjustment belt 206 is wound around the outside of the take-up and release roller 113. The positioning adjustment belt 206 passes through the adjustment belt moving frame 117 and extends to the ear adjustment mechanism 200. The adjustment belt moving frame 117 is movably connected to the first movable module 101 and the second movable module 102 through a connecting block 116.

[0024] When using, such as Figure 1 , Figure 3 , Figures 5-6 and Figure 8As shown, the device is installed in the corresponding position on the treatment chair. After the patient sits on the treatment chair, the initial restriction of the elastic limiting plate 110 is released through the insertable limiting groove 107. The patient places their chin on the flexible buffer pad of the force adjustment plate 104. Under the elastic action of the force rod 115 between the moving modules, the first movable module 101 and the second movable module 102 adaptively adjust the distance according to the width of the patient's chin to achieve initial clamping and positioning. At this time, the adjustment control chip 114 receives the start signal from the shared control platform and controls the operation of the retractable roller 113. The retractable positioning adjustment belt 206 drives the adjustment belt moving frame 117 to move, thereby linking the first movable module 101 and the second movable module 102 to fine-tune their positions. At the same time, the guide cylinder 105 slides in the cylindrical guide groove 118 to ensure the smooth movement of the force adjustment plate 104. The elastic limiting plate 110 is unidirectionally limited on the trapezoidal distance adjustment control 109 to ensure the stability of the structure after adjustment. If adjustment is needed, the limit plate 110 can be released by pulling the pullback connecting rod 112 after canceling the limit pullback groove 111, and the position can be adjusted. The whole process realizes the self-adaptation and precise adjustment of the chin fixation. The medical silicone flexible cushioning pad improves the comfort and anti-slip effect of the chin contact.

[0025] In some embodiments, such as Figure 4 and Figure 7 As shown, the ear adjustment mechanism 200 includes an adjustment mounting part 201, which is detachably connected to the two side columns 108. An angle adjustment groove 202 is formed on the surface of the adjustment mounting part 201. The angle adjustment groove 202 has an arc-shaped structure, and a rotating part 207 is slidably connected inside. One side of the rotating part 207 is fixed in position by a limiting part 203, and the other side is fixedly connected to an ear fixing ring 204. The ear fixing ring 204 has a semi-circular structure, is made of shape memory alloy, and has a sound-insulating buffer layer on its inner side. The ear fixing ring 204 is opened and closed by a quick-release buckle 205. The end of the positioning adjustment band 206 away from the retractable roller 113 is connected to the ear fixing ring 204. The adjustment mounting part 201 has a storage mold inside. Block 208, storage module 208 is connected to adjustment control chip 114 by signal. The head fastening and fixing mechanism 300 includes a top fixing strip 301. The two ends of the top fixing strip 301 are fixedly connected to the top of the middle frame 103. A size adjustment component 302 is installed at the bottom of the top fixing strip 301. The size adjustment component 302 is an electric telescopic rod structure. Its bottom is fixedly connected to the head fixing ring 303. The head fixing ring 303 is an arc-shaped structure. A flexible pad 304 is attached to the inner surface wall. The flexible pad 304 is made of memory foam material. Its surface has ventilation holes. The flexible pad 304 is detachably connected to the head fixing ring 303. A pressure sensor is installed inside the flexible pad 304. The pressure sensor is connected to adjustment control chip 114 by signal.

[0026] When using, such as Figure 4and Figure 7 As shown, the ear fixation ring 204 is opened by quick-release buckle 205, the patient's ear is placed in and then closed. The ear fixation ring 204, made of shape memory alloy, can conform to the shape of the ear and adapt to deformation. The inner sound-insulating buffer layer isolates external noise. According to the patient's head posture, the rotating part 207 is pushed to slide in the arc angle adjustment groove 202 to adjust the angle of the ear fixation ring 204. After it is in place, the position of the rotating part 207 is fixed by the limiting part 203. The positioning adjustment band 206 is connected to the ear fixation ring 204, and synchronous linkage is achieved when the chin fixation adjustment mechanism 100 is adjusted, ensuring the coordinated adaptation of ear fixation and chin fixation. The storage module 208 records the patient's ear adjustment parameters for easy reuse in subsequent diagnosis and treatment. At the same time, if Figure 2 and 5 As shown, the adjustment control chip 114, according to the instructions of the shared control platform, controls the extension and retraction of the size adjustment component 302 (electric telescopic rod) of the head fastening and fixing mechanism 300, which drives the head fixing ring 303 to move up and down to adapt to the patient's head height. The pressure sensor inside the flexible pad 304 detects the head contact pressure in real time and feeds the signal back to the adjustment control chip 114 to achieve precise control of the fixing force and avoid excessive pressure causing discomfort. The flexible pad 304, made of memory foam, has ventilation holes to improve the comfort and breathability of head contact, and the flexible pad 304 is removable for easy cleaning and replacement, ensuring hygiene and safety.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
