[0058] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text 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 invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0060] In the description of the present invention, if there are words such as "several", it means one or more, "more" means more than two, greater than, less than, exceed, etc. are understood as not including the number, and above, below, within, etc. are understood as including the number.

[0061] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0062] Pelvic and acetabular fractures are complex in anatomy, with numerous adjacent important tissues and organs, and a variety of fracture types. Traditional open reduction and internal fixation can directly visualize the injured area, which is conducive to anatomical reduction. However, during the incision, too much soft tissue is exposed, the operation is complicated, and it is easy to damage important blood vessels and nerves. Therefore, pelvic and acetabular fracture surgery is difficult, time-consuming, bleeding, and risky.

[0063] After surgery, patients with pelvic acetabular fractures need to do rehabilitation exercises in bed at home. However, due to the lack of guidance from professional medical staff during home care, the exercise movements are not standardized, and patients cannot evaluate their own recovery stage. Therefore, there is an urgent need for a rehabilitation exercise device that can guide patients to do home rehabilitation exercises and evaluate the recovery stage.

[0064] The postoperative rehabilitation exercise device for pelvic acetabular fracture of the present invention is provided in the following embodiments:

[0065] The postoperative rehabilitation exercise equipment for pelvic acetabular fracture comprises a bed body, a foot cover, a video acquisition module, a first processing module, a second processing module, a third processing module and a fourth processing module.

[0066] Positioning markers are set on the left or right side of the bed. The foot covers are designed according to the shape of the user's lower limbs. The foot covers are made of soft silicone material to facilitate users to move after wearing the foot covers.

[0067] The foot cover is cut in the middle into a left part and a right part, which are connected by Velcro or an elastic band. The user separates the left part and the right part along the left and right directions and then puts them on the outside of the lower limbs. Since the foot cover is designed according to the shape of the user's lower limbs, each part of the user's lower limbs corresponds accurately to the position of the foot cover.

[0068] Users can put on or take off the foot cover by separating the left and right parts, which is easy to operate.

[0069] In this embodiment, multiple motion markers are installed on the left side wall or the right side wall, and multiple motion markers are installed one by one on corresponding soles of the feet, ankles, calves, knees, thighs, buttocks and other parts to capture the motion trajectories of the above parts.

[0070] The movement trajectories of the soles of the feet, ankles, calves, knees, thighs, buttocks and other parts are simulated through multiple motion markers, so as to accurately analyze the rehabilitation stages of different parts and formulate more refined rehabilitation exercises.

[0071] In this embodiment, the colors of the multiple motion markers are different from each other.

[0072] This allows the image processing system to capture the motion trajectories of multiple motion markers separately, thereby avoiding interference between the multiple motion markers.

[0073] The video acquisition module is a camera device with a recording function. The video acquisition module is installed on the left or right side of the bed. The video acquisition module shoots the bed. The video acquisition module shoots the user wearing foot covers and performing rehabilitation exercises on the bed, and then outputs a video. The rehabilitation exercises performed by the user wearing foot covers include multiple action cycles, and one action cycle corresponds to a cycle of completing a specified action when the user's lower limbs perform rehabilitation exercises.

[0074] The first processing module is an image processing system, which can analyze and process the video and obtain the travel distance of each motion marker in each action cycle.

[0075] The second processing module is a data processing module, which organizes the multiple travel data obtained after being processed by the first processing module and outputs a travel change curve.

[0076] The third processing module is a data processing module, which processes preset data. The preset data can be the travel data obtained after different patients wore foot covers and shot videos during rehabilitation exercises at different rehabilitation stages in the past. All travel data are then averaged to obtain an average value for drawing a theoretical travel change curve, and then the theoretical travel change curve corresponding to the motion markers in multiple rehabilitation stages can be obtained.

[0077] The fourth processing module is a comparative analysis module, which analyzes and compares the measured stroke change curve and a plurality of theoretical stroke change curves.

[0078] Find a theoretical stroke change curve that better fits the measured stroke change curve, so as to intuitively and accurately compare the user's measured stroke change curve with the theoretical stroke change curve, and evaluate the user's recovery degree according to the recovery stage corresponding to the theoretical stroke change curve.

[0079] Reference Figures 1 to 8 The method for using the postoperative rehabilitation exercise device for pelvic acetabular fracture of the present invention is described in the following embodiments:

[0080] Reference Figure 1 As shown, the method of use includes the following steps.

[0081] Step S100, the user wears the foot cover and shoots a video of the user performing rehabilitation exercises, where the video includes multiple action cycles of the rehabilitation exercises;

[0082] Step S200, obtaining a motion curve of the motion marker in each motion cycle according to the video;

[0083] Step S300, comparing the motion curve with the first preset action curve and the second preset action curve; when the motion curve is not between the first preset action curve and the second preset action curve, determining that the exercise action does not meet the specification and issuing a reminder;

[0084] Step S400, obtaining the travel distance of the motion marker in each action cycle according to the video;

[0085] Step S500, obtaining a measured stroke variation curve according to multiple strokes;

[0086] Step S600, drawing theoretical stroke change curves corresponding to multiple rehabilitation stages according to preset data;

[0087] Step S700: After comparing the measured stroke change curve with a plurality of theoretical stroke change curves, the rehabilitation stage corresponding to the motion marker is obtained.

[0088] In step S100, a camera with a video recording function is installed on the left or right side of the bed, and the camera shoots the bed. The camera shoots the user wearing foot covers and performing rehabilitation exercises on the bed, and then outputs a video.

[0089] And the rehabilitation exercise performed by the user wearing the foot cover includes multiple action cycles, and one action cycle corresponds to a cycle of completing a specified action when the user performs the rehabilitation exercise on the lower limbs.

[0090] In step S200, the motion trajectory of the motion marker in the video is analyzed frame by frame to obtain a motion curve for each action cycle.

[0091] In step S300 , a first preset action curve and a second preset action curve are preset, and it is determined whether the motion curve is between the first preset action curve and the second preset action curve.

[0092] If the motion curve is between the first preset motion curve and the second preset motion curve, it is proved that the user's exercise action meets the specification.

[0093] If the motion curve is not between the first preset motion curve and the second preset motion curve, it is proved that the user's exercise action does not meet the specification, and a sound is emitted or a light is turned on to remind the user.

[0094] This allows users to always judge whether their exercise movements are standardized when doing rehabilitation exercises at home. If not, they can adjust their movements in time to improve the user's exercise effect.

[0095] In step S400, the motion trajectory of the motion marker in the video is analyzed frame by frame.

[0096] For example, taking the straight leg raising training after the user lies on his back, the first position of the motion marker is obtained when the user puts down his legs on the bed, and the second position of the motion marker is obtained when the user raises his legs to the highest point. The movement of the user's legs from the first position to the second position and then returning to the first position is one action cycle. Therefore, the trajectory length of the motion marker from the first position to the second position can be used as the stroke corresponding to one action cycle.

[0097] Of course, users can also perform other lower limb training. According to the above principles, the corresponding motion trajectory can also be output, and the stroke corresponding to each action cycle can be obtained.

[0098] After the user performs multiple action cycles in rehabilitation exercise, the user's second position changes due to fatigue in the user's lower limbs, so the strokes corresponding to different action cycles also change.

[0099] In step S500, multiple travels of the motion markers are sorted out to generate a measured travel change curve of each motion marker.

[0100] In step S600, the preset data is processed. The preset data may be the travel data obtained after different patients wore foot covers and shot videos during rehabilitation exercises at different rehabilitation stages in the past. All the travel data are then averaged to obtain an average value for drawing a theoretical travel change curve, thereby obtaining the theoretical travel change curve corresponding to the motion markers in multiple rehabilitation stages.

[0101] In step S700, the measured stroke variation curve and a plurality of theoretical stroke variation curves are analyzed and compared.

[0102] Find a theoretical stroke change curve that better fits the measured stroke change curve, so as to intuitively and accurately compare the user's measured stroke change curve with the theoretical stroke change curve, and evaluate the rehabilitation degree of the corresponding part of the motion marker according to the rehabilitation stage corresponding to the theoretical stroke change curve.

[0103] A video acquisition module is used to capture a video of a user wearing a foot cover for rehabilitation exercise, and the motion curve of the motion marker is used to determine whether the user's exercise movements are in compliance with the specifications. When the exercise movements are not in compliance with the specifications, a reminder is issued to correct the user's exercise movements. The stroke corresponding to the motion marker in each action cycle is acquired based on the video, and then a measured stroke change curve is obtained based on multiple strokes. Theoretical stroke change curves corresponding to multiple rehabilitation stages are drawn based on preset data of the rehabilitation exercise equipment. The measured stroke change curve is compared with multiple theoretical stroke change curves to obtain a theoretical stroke change curve corresponding to the measured stroke change curve, and then the rehabilitation stage corresponding to the motion marker is output, so as to accurately evaluate the rehabilitation stage of the part corresponding to the motion marker, so as to perform refined rehabilitation exercises on different parts of the user.

[0104] Reference Figure 2 As shown, step S300, comparing the motion curve with the first preset action curve and the second preset action curve includes the following steps.

[0105] Step S310: the remote control module pre-stores a plurality of exercise modes, each of which is respectively set with a first preset action curve and a second preset action curve, and the terminal sets the exercise mode to the remote control module;

[0106] Step S320: the remote control module sends the rehabilitation stage corresponding to each motion marker to the terminal.

[0107] In step S310, the medical staff can send a signal to the remote control module through remote communication at the terminal, and select one of the multiple exercise modes pre-stored in the remote control module for the user to perform rehabilitation exercises, so that the medical staff can remotely guide the user.

[0108] Each exercise mode is set with a first preset action curve and a second preset action curve, so as to compare the action curves of the user and standardize the user's exercise actions.

[0109] In step S320, the remote control module sends the rehabilitation stages corresponding to the user's multiple motion markers to the terminal, and the medical staff can view the rehabilitation status of various parts of the user from the terminal, so that the medical staff can adjust the exercise mode in time.

[0110] Reference Figure 3 As shown, step S400, obtaining the travel of the motion marker in each action cycle according to the video includes the following steps.

[0111] Step S410, establishing a first coordinate system with the positioning marker as the origin, and obtaining a motion trajectory of the motion marker in the first coordinate system according to the video;

[0112] Step S420, dividing the motion trajectory into multiple motion curves according to multiple action cycles;

[0113] Step S430, obtaining multiple strokes of the motion marker according to the multiple motion curves.

[0114] In step S410, refer to Figure 8 As shown, the positioning marker is set at the position of the bed corresponding to the patient's waist, and the user wears foot covers to perform straight leg raising training.

[0115] A first coordinate system is established with the positioning marker as the origin, the horizontal distance along the extension direction of the user's legs as the abscissa, and the vertical distance perpendicular to the horizontal distance as the ordinate.

[0116] Therefore, when the user wears the foot cover to perform straight leg raising training, the movement trajectories of multiple motion markers are as follows: Figure 8 As shown, the motion trajectory of the motion marker in the first coordinate system is in the shape of an arc.

[0117] Of course, if the user wears the foot covers to perform other lower limb training, the corresponding motion trajectory can also be generated in the first coordinate system.

[0118] Each arrow in the figure represents the highest point reached after extending upward from the horizontal axis. That is to say, after multiple action cycles, the user's lower limb strength gradually declines, causing the height of the leg lift to gradually decrease, causing the highest point reached by the motion marker to gradually decrease.

[0119] In step S420, the motion trajectory of the motion marker is divided into multiple segments based on an action cycle to form multiple motion curves, each of which is the motion trajectory of the motion marker after the user performs a leg-lifting action.

[0120] In step S430, the travel distance corresponding to each segment of the motion curve is calculated to obtain the travel distances corresponding to the multiple segments of the motion curves of the motion marker.

[0121] The above scheme can accurately obtain the travel distance of each motion marker in each action cycle.

[0122] Reference Figure 4 As shown, step S500, obtaining a measured stroke change curve according to multiple strokes of the motion marker includes the following steps.

[0123] Step S510 , establishing a second coordinate system with the sequence of the action cycles as the horizontal coordinate and the stroke size as the vertical coordinate.

[0124] Step S520: plotting the multiple strokes into the second coordinate system, and sequentially connecting the endpoints of the multiple strokes to form a measured stroke change curve.

[0125] In step S510, refer to Fig. 9 As shown, the horizontal axis of the second coordinate system is the order of the action cycle, and the vertical axis of the second coordinate system is the stroke.

[0126] In step S520, each action cycle and its corresponding stroke obtained in step S400 can be plotted in the second coordinate system, and the endpoints of the stroke are sequentially connected in the order of the action cycles to draw a measured stroke change curve.

[0127] The above scheme generates an intuitive measured stroke change curve.

[0128] Reference Figure 5 As shown, step S700, after comparing the measured stroke change curve with a plurality of theoretical stroke change curves, obtaining the rehabilitation stage corresponding to the motion marker includes the following steps.

[0129] Step S710, integrating the measured stroke change curve and a plurality of theoretical stroke change curves into the same coordinate system;

[0130] Step S720, finding the theoretical stroke change curve below the measured stroke change curve and the corresponding rehabilitation stage.

[0131] In step S710, refer to Fig. 9 As shown, the theoretical stroke change curves corresponding to different rehabilitation stages are plotted in the second coordinate system, and the measured stroke change curves are plotted in the second coordinate system. Fig. 9 It corresponds to the sports landmark at the ankle.

[0132] It can be seen that due to the difference in rehabilitation stages, the theoretical stroke change curves are arranged from bottom to top. The higher the rehabilitation stage, the higher the position of the theoretical stroke change curve. This is because at a higher rehabilitation stage, the user's lower limb strength and endurance are in a better state. Therefore, the user's activity stroke is larger during rehabilitation exercise, and the amount of stroke reduction caused by the increase in the action cycle is also smaller. Therefore, it can be concluded that Fig. 9 Schematic diagram of multiple theoretical stroke change curves shown.

[0133] In step S720, a theoretical stroke change curve located below the measured stroke change curve is found, and the corresponding rehabilitation stage can be output as the rehabilitation stage of the user.

[0134] For example Fig. 9 The theoretical stroke change curve corresponding to the second highest rehabilitation stage shown is located below the measured stroke change curve, thus proving that the user's rehabilitation stage is higher than the second highest rehabilitation stage.

[0135] Reference Figure 6 As shown, the method of use also includes the following steps.

[0136] Step S800, setting a plurality of rehabilitation stages corresponding to each motion marker;

[0137] Step S810, drawing a theoretical stroke change curve for each rehabilitation stage.

[0138] Since the multiple motion markers on the foot cover correspond to different parts of the user's lower limbs, multiple rehabilitation stages can be set for each motion marker, and the corresponding theoretical stroke change curve can be drawn for the rehabilitation stage, so as to evaluate the rehabilitation stage of the parts corresponding to all motion markers and perform more targeted and refined exercises on various parts of the lower limbs.

[0139] Reference Figure 7 As shown, the method of use also includes the following steps.

[0140] Step S90, designing a foot cover according to the shape of the user's lower limbs.

[0141] Step S91, setting a plurality of motion markers on the user's buttocks, thighs, knees, calves, ankles, and soles of the feet in a one-to-one correspondence.

[0142] To make the shape of the foot cover more consistent with the shape of the user's lower limbs, the foot cover can generate a three-dimensional model after a three-dimensional scan of the user's lower limbs, and then design a corresponding foot cover model based on the three-dimensional model. Finally, the foot cover is manufactured through three-dimensional printing, so that multiple sports markers can accurately correspond to different parts of the user.

[0143] The remote control module and the terminal may be two communication devices that communicate with each other.
