Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a multi-dimensional adaptive orthopedic trauma support device. Background Technology

[0002] Limb fractures, joint dislocations, and soft tissue injuries are the most common types of trauma in orthopedic clinics. Postoperative limb elevation is a core rehabilitation measure to promote venous blood return, reduce limb swelling, and prevent deep vein thrombosis. Simultaneously, stable support of the affected limb is necessary to prevent secondary injury caused by traction on the wound site during limb movement. In clinical practice, existing support structures suffer from the following unresolved technical defects and application pain points:

[0003] 1. The suspension height of the existing support device relies entirely on the pitch angle adjustment of the horizontal plate, which can easily lead to tilting and uneven force distribution after the affected limb is placed. It is impossible to accurately control the clinically required elevation angle of the affected limb (such as 30° elevation after lower limb surgery), which can easily cause misalignment of the affected limb, affect fracture reduction and healing, and even cause secondary injury.

[0004] Second, the existing support adjustment mechanism is a manual static pre-adjustment mode, which requires medical staff to manually preset the support height and support force before use. It cannot dynamically compensate the support force according to real-time working conditions such as changes in the weight of the affected limb, adjustment of the suspension height, and swaying of the patient's limb. When the affected limb sways or the suspension height is adjusted, stress changes will occur at the hinge of the horizontal plate and the vertical column. Long-term use can easily cause structural deformation, wear and even breakage of the hinge, which not only greatly shortens the service life of the device, but also poses a safety hazard of the affected limb falling due to structural failure.

[0005] Third, existing limb clamping structures are mostly rigid clamps or simple binding fixation, which cannot adapt to the contour of the affected limb. The clamping force is uncontrollable, which can easily lead to problems such as excessive clamping causing blood circulation obstruction or excessive clamping causing the affected limb to fall off. At the same time, the clamping structures are mostly fixed, which cannot be quickly changed to fit according to the location of the affected limb, limb size, and plaster thickness. The fit is extremely poor for children and patients with severe limb swelling. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a multi-dimensional adaptive orthopedic trauma support device that solves the core problems of unstable fixation, poor versatility, and insufficient safety in existing technologies. It enables multi-dimensional precise adjustment and adaptive dynamic fixation of the affected limb support, and comprehensively meets the clinical needs of orthopedic trauma patients throughout the entire clinical cycle from the postoperative acute phase to the rehabilitation phase.

[0007] The technical solution adopted in this invention is: a multi-dimensional adaptive orthopedic trauma support device, comprising a bed edge clamping mechanism, a rotating column, a horizontal suspension mechanism, and an adaptive clamping mechanism; the lower end of the rotating column is rotatably fitted with a lower horizontal plate, the other end of the lower horizontal plate is rotatably connected to the bed edge clamping mechanism, the end of the lower horizontal plate is provided with a driving mechanism for driving the rotating column to rotate around its own axis, and the upper end of the bed edge clamping mechanism is provided with a locking mechanism for locking the angle of the lower horizontal plate; the horizontal suspension mechanism includes an upper horizontal plate, a sliding seat, and a suspension block, one end of the upper horizontal plate is hinged to the upper end of the rotating column, so that the upper horizontal plate can rotate around the rotating column. The upper end of the column rotates, and the sliding seat is slidably mounted on the upper horizontal plate. The lower end of the sliding seat is connected to the suspension block through a telescopic component. A pair of side support rods are hinged to the outside of the rotating column, and the other end of the side support rod can be properly engaged with the suspension block.

The bottom and side walls of the clamping block are respectively provided with interconnected support airbags and side airbags. An elastic support frame is provided inside the support airbag. When the elastic support frame is compressed, the side airbag can be expanded to provide lateral support for the affected limb when the support airbag is compressed.

[0008] In this technical solution, the entire device is fixed to the edge of the patient's bed via a bed-edge clamping mechanism before use. The lower horizontal plate can rotate around the bed-edge clamping mechanism, allowing the rotating column to move to the area corresponding to the patient's upper or lower limbs. A locking mechanism is used to lock the rotating column, preventing it from moving. Simultaneously, a drive mechanism can rotate the rotating column, allowing the adaptive clamping mechanism to move to the optimal suspension area. A sliding seat is slidably mounted on the horizontal plate of the horizontal suspension mechanism. The sliding seat and the suspension block can be telescopically adjusted to regulate the height of the clamping block. Through multi-dimensional adjustment, the device precisely controls the patient's position. The support height and angle of the patient's affected limb; during use, the patient's affected limb is placed inside the clamping block, and under its own weight, it compresses the support airbag, while the limb is supported by the elastic support frame. After the support airbag is compressed, the side airbags expand to achieve the purpose of lateral support for the affected limb, thereby ensuring the stability and support comfort of the clamping block for the affected limb; during this process, the side support rod on the outside of the rotating column can also be connected to the suspension block to fix the suspension block and prevent the suspension structure from shaking, so as to achieve the purpose of precisely controlling the elevation angle of the affected limb and avoiding the problem of misalignment of force line caused by the shaking of the affected limb, which would affect the fracture reduction and healing and cause secondary injury.

[0009] Preferably, the bed edge clamping mechanism includes an upper fixed block, a lower fixed block, a bidirectional adjusting screw, and a C-shaped fixed seat. The upper and lower fixed blocks are arranged opposite each other and slide in cooperation with the side wall of the sliding seat. The bidirectional adjusting screw is vertically rotatably installed in the fixed seat and is threadedly engaged with the upper and lower fixed blocks. The upper end of the fixed seat is rotatably engaged with the end of the lower horizontal plate away from the rotating column.

[0010] Preferably, the locking mechanism includes an angle locking pin inserted at the upper end of the lower horizontal plate near the fixed seat, and multiple locking holes adapted to the angle locking pin are evenly distributed circumferentially on the outer side of the fixed seat. A spring is sleeved on the upper part of the lower horizontal plate corresponding to the angle locking pin, so that the angle locking pin can automatically engage with the locking hole under the action of elastic force. A handle is also provided at the upper end of the angle locking pin.

[0011] Preferably, a dynamic stress support mechanism is provided between the outer side of the rotating column and the upper horizontal plate, including a servo electric cylinder. The servo electric cylinder is signal-connected to a control module. One end of the servo electric cylinder is hinged to the outer side of the rotating column, and the other end is hinged to a support block located at the bottom of the upper horizontal plate. A pressure sensor is provided between the support block and the upper horizontal plate. The pressure sensor is electrically connected to the control module. The control module adjusts the extension and retraction of the servo electric cylinder and the output thrust in real time according to the pressure value.

[0012] Preferably, the bottom of the upper horizontal plate is provided with a linear guide rail that extends along its length and slides in cooperation with the sliding seat. The bottom of the upper horizontal plate is also provided with a lead screw module that passes through the sliding seat and is threadedly engaged with the sliding seat. The lead screw module is connected to a motor module for transmission.

[0013] Preferably, the upper end of the supporting airbag and the opposite sides of the two airbags are provided with hollowed-out supporting pads.

[0014] Preferably, the upper ends of the clamping block are equipped with clamping claws on both sides via a rotating shaft, and a torsion spring is mounted on the rotating shaft.

[0017] Preferably, the upper end of the rotating column is provided with an angle disc, and the end of the upper horizontal plate near the angle disc is provided with an angle pointer.

[0018] The beneficial effects of this invention are:

[0019] 1. This invention, through the cooperation of a bed edge clamping mechanism, a rotatable lower horizontal plate, an axially rotatable rotating column, a sliding sliding seat, and a telescopic component, achieves multi-dimensional independent adjustment of the affected limb's support position, including horizontal rotation, lateral translation, and vertical lifting. This solves the problem of coupling height and angle adjustment in existing devices; it ensures that the affected limb is always at the clinically required elevation angle, precisely controls the limb's force line, and avoids problems such as poor venous return and loss of fracture reduction caused by limb tilting and force line deviation. This fundamentally reduces the risk of secondary injury and ensures postoperative rehabilitation.

[0020] 2. The adaptive clamping mechanism in this invention adopts a structural design that links the support airbag and the side airbag, which can achieve adaptive clamping and fixation of the affected limb without manual operation. With the elastic support frame inside the support airbag, it not only ensures the stability of the fixation of the affected limb and eliminates the risk of loosening and displacement of the affected limb, but also avoids the pressure of rigid clamping on the affected limb through the flexible cushioning of the airbag, effectively preventing pressure sores and blood circulation disorders. At the same time, the clamping block and the suspension block adopt a quick-release connection, and the appropriate clamping block can be quickly replaced according to the location and size of the affected limb, which is highly adaptable.

[0021] 3. In this invention, the dynamic stress adaptive support system consists of a servo electric cylinder, a pressure sensor, and a control module to form a dynamic stress support mechanism. The control module can automatically adjust the output thrust and extension of the servo electric cylinder according to the real-time changes in working conditions such as the weight of the affected limb, the suspension height, and the limb swaying, so as to provide real-time dynamic support for the upper horizontal plate, continuously counteract the bending stress at the hinge of the upper horizontal plate and the rotating column, avoid structural deformation and wear caused by sudden stress changes, and eliminate safety hazards caused by structural failure.

Detailed Implementation

[0026] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0027] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0028] like Figure 1 and Figure 2 As shown in the figure, a specific embodiment of the present invention provides a multi-dimensional adaptive orthopedic trauma support device, including a bed edge clamping mechanism, a rotating column 100, a horizontal suspension mechanism, and an adaptive clamping mechanism; wherein the rotating column 100 is a vertically arranged circular column, and its lower end is rotatably mounted with a horizontally arranged lower cross plate 200 via a thrust bearing. The end of the lower cross plate 200 away from the rotating column 100 is rotatably connected to the bed edge clamping mechanism, so that the lower cross plate 200 can drive the rotating column 100 to rotate 360° in the horizontal plane, adapting to the different suspension area needs of the patient's upper and lower limbs; the lower cross plate 200 is provided with a drive mechanism for driving the rotating column 100 to rotate around its own axis, and the upper end of the bed edge clamping mechanism is provided with a locking mechanism for locking the rotation angle of the lower cross plate 200.

[0029] like Figure 1 and Figure 2As shown, the above-mentioned horizontal suspension mechanism includes an upper horizontal plate 300, a sliding seat 400, and a suspension block 500. One end of the upper horizontal plate 300 is hinged to the upper end of the rotating column 100, allowing the upper horizontal plate 300 to rotate around the upper end of the rotating column 100. The sliding seat 400 is slidably mounted on the upper horizontal plate 300. The lower end of the sliding seat 400 is connected to the suspension block 500 through a telescopic member 600. The telescopic member 600 adopts a threaded telescopic rod structure, which can precisely control the telescopic stroke and realize stepless precise adjustment of the vertical height of the suspension block 500. A pair of side support rods 700 are hinged to the outside of the rotating column 100. The other end of the side support rod 700 can be fitted with the suspension block 500 to suppress the multi-dimensional swing of the suspension block 500 and prevent the affected limb from shaking and pulling on the injured area.

[0030] like Figure 1 and Figure 2 As shown, the adaptive clamping mechanism described above includes a U-shaped clamping block 800. The upper end of the clamping block 800 is detachably connected to the lower end of the suspension block 500. The bottom and side walls of the clamping block 800 are respectively provided with interconnected support airbags 900 and side airbags 1000. An elastic support frame 1100 is provided inside the support airbag 900. When the elastic support frame 1100 is compressed, the side airbags 1000 can be opened to provide lateral support for the affected limb.

[0031] like Figure 1 and Figure 2As shown, with the above configuration, the entire device provided in this embodiment is fixed to the edge of the patient's bed by the bedside clamping mechanism before use. The lower horizontal plate 200 can rotate around the bedside clamping mechanism, allowing the rotating column 100 to move to the area corresponding to the patient's upper or lower limbs. A locking mechanism is used to lock the rotating column 100, preventing it from moving. Simultaneously, the rotating column 100 can be rotated via a drive mechanism, allowing the adaptive clamping mechanism to move to the optimal suspension area. A sliding seat 400 is slidably mounted on the horizontal plate of the horizontal suspension mechanism. The sliding seat 400 and the suspension block 500 can also be telescopically adjusted to adjust the clamping force of the clamping mechanism. The holding block 800 is positioned at a specific height. During use, the patient's affected limb is placed inside the holding block 800. Under its own weight, the limb presses downwards against the support airbag 900, compressing it. The gas inside the support airbag 900 inflates through the ventilation channel into the side airbags 1000 on both sides, causing them to expand inwards simultaneously, forming a wraparound support for both sides of the affected limb. This achieves self-adaptive clamping and fixation of the affected limb without manual inflation or adjustment. The elastic support frame 1100 provides elastic cushioning when the support airbag 900 is compressed, preventing rigid contact between the affected limb and the holding block 800, while ensuring the stability of the support at the base of the affected limb. During this process, the side support rod 700 on the outer side of the rotating column 100 can also connect to the suspension block 500, fixing the suspension block 500 and preventing swaying of the suspension structure. This allows for precise control of the limb's elevation angle, preventing secondary injuries caused by misalignment of the affected limb, which could affect fracture reduction and healing.

[0032] like Figure 1 and Figure 2 As shown, the bed edge clamping mechanism provided in this embodiment includes an upper fixing block 1200, a lower fixing block 1300, a bidirectional adjusting screw 1400, and a C-shaped fixing seat 1500. The upper fixing block 1200 and the lower fixing block 1300 are arranged opposite each other and slide in cooperation with the side wall of the sliding seat 400. The bidirectional adjusting screw 1400 is vertically rotatably installed in the fixing seat 1500, and the bidirectional adjusting screw 1400 is threadedly engaged with the upper fixing block 1200 and the lower fixing block 1300. The upper end of the fixing seat 1500 is rotatably engaged with the end of the lower horizontal plate 200 away from the rotating column 100. In this way, when in use, the C-shaped opening of the fixing seat 1500 is inserted into the bed edge or bedside crossbar, and the bidirectional adjusting screw 1400 is rotated to drive the upper fixing block 1200 and the lower fixing block 1300 to move synchronously towards each other, reducing the clamping distance and firmly fixing the device to the bed edge. This structure is easy to assemble and disassemble, has strong clamping stability, and can be adapted to bed edges of different specifications with a thickness of 2-15cm, making it extremely versatile.

[0033] As mentioned above, the lower horizontal plate 200 and the fixed seat 1500 are rotatably engaged, so that the rotation of the lower horizontal plate 200 drives the rotating column 100 to move to the corresponding suspension support position. The locking mechanism in this embodiment includes an angle locking pin 1600 inserted at the upper end of the lower horizontal plate 200 near the fixed seat 1500. The outer side of the fixed seat 1500 is evenly distributed with a plurality of locking holes 1510 that are adapted to the angle locking pin 1600. The angle locking pin 1600 is fitted with a spring corresponding to the upper part of the lower horizontal plate 200, so that the angle locking pin 1600 can automatically be inserted into the locking hole 1510 under the action of elastic force. The upper end of the angle locking pin 1600 is also provided with a handle. In this way, when medical staff use the device, they can pull the angle locking pin 1600 upwards by pulling the handle, so that its bottom end is disengaged from the locking hole 1510, and the lower horizontal plate 200 can be freely rotated to adjust the suspension area. After adjustment, the handle is released, and the angle locking pin 1600 automatically engages with the corresponding locking hole 1510 under the elastic force of the spring, realizing the quick locking of the rotation angle of the lower horizontal plate 200, preventing the rotating column 100 from shifting during use, and ensuring the stability of the suspension position.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, a dynamic stress support mechanism is provided between the outer side of the rotating column 100 and the upper horizontal plate 300, including a servo electric cylinder 1600. The servo electric cylinder 1600 is signal-connected to a control module. One end of the servo electric cylinder is hinged to the outer side of the rotating column 100, and the other end is hinged to a support block located at the bottom of the upper horizontal plate 300. A pressure sensor is provided between the support block and the upper horizontal plate 300. The pressure sensor is electrically connected to the control module. The control module adjusts the extension and retraction of the servo electric cylinder and the output thrust in real time according to the pressure value. In this way, during use, the pressure sensor can collect the load-bearing pressure data of the upper horizontal plate 300 in real time and transmit it to the control module. The control module automatically adjusts the extension and retraction of the servo cylinder 1600 and the output thrust according to the preset safety threshold and real-time pressure changes: when the weight of the affected limb increases, the suspension height decreases, or the limb swaying causes the stress at the hinge of the upper horizontal plate 300 to increase, the control module automatically increases the output thrust of the servo cylinder 1600 to provide stable support for the upper horizontal plate 300 and continuously counteract the bending stress at the hinge; when the suspension height increases and the load-bearing pressure decreases, the control module synchronously adjusts the extension and retraction of the servo cylinder 1600 to ensure dynamic matching between the support force and the load-bearing pressure, and avoid structural deformation and wear caused by sudden stress changes.

[0035] like Figure 1 and Figure 2As shown, in order to slidably mount the sliding seat 400 on the upper horizontal plate 300, this embodiment provides a linear guide rail at the bottom of the upper horizontal plate 300 that extends along its length and slides in cooperation with the sliding seat 400. The bottom of the upper horizontal plate 300 also provides a lead screw module 1700 that passes through the sliding seat 400 and is threadedly engaged with the sliding seat 400. The lead screw module 1700 is connected to a motor module. By controlling the motor module to operate, the lead screw can be rotated, thereby driving the sliding seat 400 to move precisely along the linear guide rail, adjusting the lateral position of the suspension block 500, and adapting to the suspension position requirements of different patients and different trauma sites.

[0036] In this embodiment, hollowed-out support pads are provided on the upper end of the support airbag 900 and on the opposite sides of the two side airbags 1000 to reduce the contact area between the support structure and the affected limb, thereby improving the support comfort of the affected limb.

[0037] As mentioned earlier, the clamping block 800 and the suspension block 500 are detachably connected. To facilitate disassembly and assembly, in this embodiment, clamping claws 1800 are rotatably mounted on both sides of the upper end of the clamping block 800 via a rotating shaft. A torsion spring is mounted on the rotating shaft. The upper end of the clamping claw 1800 is provided with a clamping part, and the lower end is provided with a pressing part. The outer side of the suspension block 500 is provided with a clamping groove that fits properly with the clamping part. Here, the torsion spring provides locking force for the clamping claw 1800. During disassembly and assembly, pressing the pressing part at the lower end of the clamping claws 1800 on both sides overcomes the elastic force of the torsion spring, causing the clamping part at the upper end of the clamping claw 1800 to open outward, thus removing the clamping block 800 from the lower end of the suspension block 500. After aligning with the installation position, releasing the pressing part causes the clamping part to automatically engage with the clamping groove under the elastic force of the torsion spring, achieving quick installation of the clamping block 800. This quick-release structure allows for rapid replacement of the appropriate clamping block 800 based on the patient's affected limb location, limb size, and plaster thickness, significantly improving the device's clinical adaptability.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the driving mechanism for driving the rotating column 100 to rotate includes a gear located inside the lower horizontal plate 200 and connected to the rotating column 100. The gear is connected to a worm gear, and one end of the worm gear extending out of the lower horizontal plate 200 is connected to an adjusting handwheel 1900. By rotating the adjusting handwheel 1900, the worm gear structure drives the rotating column 100 to rotate axially. At the same time, the worm gear has a self-locking function to ensure the stability of the rotating column 100 after it is adjusted to the correct position.

[0039] like Figure 1 and Figure 2As shown, in this embodiment, the upper end of the suspension block 500 is provided with a universal ball joint module 2000, which is fixedly connected to the lower end of the telescopic member 600. The universal ball joint module 2000 is provided with a locking handle, which can lock the ball joint after the angle adjustment is completed. The pitch and deflection angles of the suspension block 500 and the lower clamping block 800 can be flexibly adjusted through the universal ball joint module 2000 to ensure that the affected limb is always in a horizontal position or at the clinically required elevation angle after placement, accurately control the force line of the affected limb, and adapt to the support needs of different body positions.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
