Technical Field

[0001] The present invention relates to the field of medical information technology, and in particular to an evaluation system for lumbar manipulation. Background Art

[0002] In recent years, the number of patients with lumbar diseases in my country has been growing continuously. The number of patients with lumbar diseases in China is huge. Lumbar lesions are one of the main causes of low back pain and back and leg pain. Lumbar manipulation is a highly skilled medical operation technology with the characteristics of stable, accurate, light and clever operation. It requires a high degree of coordination of movements and amplitudes, and has relatively high technical requirements for the operator.

[0003] Although the steps of the manipulation have been standardized, there are no objective technical indicators as a reference, which requires beginners to spend a lot of time practicing and exploring in clinical work before they can master the essence of the manipulation. Therefore, the learning efficiency is low and it is difficult to promote it. In the process of existing manipulation, the quality of the operation is greatly affected by human factors, which is difficult to master and difficult to promote on a large scale.

[0004] Therefore, in order to ensure the consistency of the quality of lumbar manipulation, automated evaluation of lumbar manipulation is needed. Summary of the invention

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Please refer to Figure 1 The embodiment of the present invention provides a lumbar manipulation evaluation system, the system comprising:

[0023] Operating device (i.e. Figure 1 The structure shown in the figure is used to collect the lumbar manipulation operation to be evaluated. The outer part of the operating device is used to cover the upper body of the dummy (not shown in the figure), and the upper body includes the head, chest and waist. The operating device includes a posture sensor 11 for collecting head kinematic data, a pressure sensor 12 for collecting waist pressure and a tension sensor for collecting chest tension (not shown in the figure). The kinematic data includes motion trajectory, acceleration and angular velocity. The lumbar manipulation operation to be evaluated includes data collected by the posture sensor 11, the pressure sensor 12 and the tension sensor;

[0024] An evaluation device (not shown in the figure) is electrically connected to the posture sensor 11, the pressure sensor 12 and the tension sensor respectively. The evaluation device is used to compare the lumbar manipulation operation to be evaluated with the preset standard lumbar manipulation operation to obtain an evaluation result of the lumbar manipulation operation to be evaluated.

[0025] In this embodiment, the lumbar manipulation to be evaluated can be obtained by using the operating device, and then the evaluation device uses the pre-set standard lumbar manipulation to evaluate the lumbar manipulation to be evaluated, so as to obtain the evaluation result of the lumbar manipulation to be evaluated. Therefore, the above scheme can realize the automated evaluation of the lumbar manipulation, thereby ensuring the consistency of the quality of the lumbar manipulation.

[0026] Please continue reading Figure 1In one embodiment of the present invention, the operating device includes a first base 13, a second base 14 fixed above the first base 13, a simulated lumbar vertebra component 15 and a simulated thoracic vertebra component 16 fixed on the second base 14, the simulated thoracic vertebra component 16 is connected to the simulated lumbar vertebra component 15 and is located above the simulated lumbar vertebra component 15, the top of the simulated thoracic vertebra component 16 is used to cover the head of the dummy, the simulated thoracic vertebra component 16 is used to cover the chest of the dummy, and the simulated lumbar vertebra component 15 is used to cover the waist of the dummy, the posture sensor 11 is arranged on the top of the simulated thoracic vertebra component 16, and the pressure sensor 12 is arranged on one side of the simulated lumbar vertebra component 15;

[0027] A plurality of driving devices 17 are arranged on the first base 13, and the driving devices 17 are connected to the simulated thoracic vertebra assembly 16 via a traction rope 18, and a tension sensor is connected between the driving devices 17 and the traction rope 18;

[0028] When performing lumbar manipulation, the simulated lumbar component 15 rotates, the simulated thoracic component 16 bends, the posture sensor 11 collects head kinematic data in real time, the pressure sensor 12 collects waist pressure in real time, and the tension sensor collects chest tension in real time;

[0029] After completing the lumbar manipulation, the driving device 17 is used to drive the traction rope 18 to drive the simulated thoracic spine component 16 to reset.

[0030] In this embodiment, the rigidity of the driving device 17 itself is used as the mechanical property of a specific lumbar patient, so that when the person being tested performs lumbar manipulation on the upper body of the dummy, feedback similar to that of a real lumbar patient can be generated, which is beneficial to ensure the consistency of the test of the person being tested.

[0031] In some embodiments, the driving device 17 may be a motor, or a hydraulic pump or an air pump, which is not specifically limited here, and preferably a motor is used.

[0032] In one embodiment of the present invention, the lumbar manipulation to be evaluated is collected in the following manner:

[0033] By pressing the dummy's waist with one hand and the dummy's head with the other hand, the dummy's waist is rotated while the dummy's head and chest are lowered, so as to realize the bending of the simulated thoracic vertebra component 16 and the rotation of the simulated lumbar vertebra component 15, so that the posture sensor 11, the pressure sensor 12 and the tension sensor can collect real-time data, and finally generate the lumbar manipulation operation to be evaluated.

[0034] In one embodiment of the present invention, two damping rods 19 symmetrically arranged relative to the simulated thoracic vertebra assembly 16 are arranged on the second base 14 . The damping rods 19 can bend and contract as the simulated thoracic vertebra assembly 16 bends, and can extend and gradually become vertical relative to the second base 14 as the simulated thoracic vertebra assembly 16 is reset.

[0035] In this embodiment, by providing the damping rod 19, the stability of the upper body of the dummy during the bending and resetting process can be effectively increased.

[0036] In one embodiment of the present invention, a propulsion rod 20 is provided on the second base 14, and the propulsion rod 20 and the pressure sensor 12 are provided on both sides of the simulated thoracic vertebra assembly 16. The connecting line of the propulsion rod 20 and the pressure sensor 12 is perpendicular to the connecting line of the two damping rods 19. When the simulated thoracic vertebra assembly 16 is bent, the propulsion rod 20 is in a retracted state relative to the second base 14. When the simulated thoracic vertebra assembly 16 is reset, the propulsion rod 20 is in an extended state relative to the second base 14 to press against the chest of the dummy until the dummy is completely reset.

[0037] In this embodiment, it is difficult to completely reset the upper body of the dummy by relying solely on the driving device 17. By setting up a push rod 20, the upper body of the dummy can be assisted to be completely reset, and the connection line between the push rod 20 and the pressure sensor 12 is perpendicular to the connection line between the two damping rods 19, which can ensure the stability and authenticity of the lumbar manipulation process.

[0038] like Figure 2 As shown, in one embodiment of the present invention, the simulated thoracic vertebra assembly 16 includes a plurality of simulated thoracic vertebra units 2 connected in sequence, each simulated thoracic vertebra unit 2 includes a first connecting plate 21, a second connecting plate 22, a first spring 23, a first sleeve 24, a ball 25 and an insertion rod 26, the first spring 23 is connected between the first connecting plate 21 and the second connecting plate 22, the ball 25 is rotatably embedded in the first sleeve 24, the first sleeve 24 is connected to the first connecting plate 21, a cylindrical cavity is arranged in the ball 25, one end of the insertion rod 26 is inserted in the cylindrical cavity, and the other end is connected to the second connecting plate 22, and the first spring 23 is sleeved on the outside of the first sleeve 24, the ball 25 and the insertion rod 26.

[0039] In this embodiment, by setting the sphere 25, the real bending characteristics of the thoracic vertebra can be simulated, that is, a thoracic vertebra is not completely in a bent state, but in a thoracic vertebra, the lower part is relatively rigid, while the upper part is relatively flexible. Therefore, the first sleeve 24 is used to simulate the lower part of a thoracic vertebra, and the insertion rod 26 and the sphere 25 are used to simulate the upper part of a thoracic vertebra, so that a more realistic and accurate evaluation result can be obtained.

[0040] like Figures 3 to 6As shown, in one embodiment of the present invention, the simulated lumbar vertebra component 15 includes a second sleeve 31, a third sleeve 32, a bearing 33, a roller 34 and a chassis 35, the top of the second sleeve 31 is connected to the bottom simulated thoracic vertebra component 16, the roller 34 is connected to the second sleeve 31, the top of the third sleeve 32 is fixed to the second base 14, the outer ring of the bearing 33 is fixed to the third sleeve 32, the inner ring of the bearing 33 is fixed to the second sleeve 31, the bottom of the third sleeve 32 is fixed to the chassis 35, and the upper surface of the chassis 35 is provided with at least two arc segments 351 connected to each other and having different curvatures, and the arc segments 351 are used to characterize the mechanical properties of lumbar patients;

[0041] When the second sleeve 31 rotates, the second sleeve 31 drives the roller 34 to rotate together, so that the roller 34 rolls on the upper surface of the bottom plate 35 .

[0042] In this embodiment, by providing at least two interconnected arc segments 351 with different curvatures on the upper surface of the chassis 35, the arc segments 351 can be used to characterize the mechanical properties of lumbar patients to simulate the mechanical conditions of real lumbar patients, that is, in the final state, the lumbar manipulation will eventually cause the lumbar vertebra of the lumbar patient to be repositioned, thereby generating a "click" sound, so Figure 6 The higher arc segment 351 shown represents the final treatment condition.

[0043] In one embodiment of the present invention, the simulated lumbar vertebra component 15 also includes a motor 36, a fourth shaft sleeve 37 and a connecting shaft 38. The chassis 35 is fixed to the top of the motor 36, the top of the fourth shaft sleeve 37 is fixed to the bottom of the second shaft sleeve 31, and the bottom of the fourth shaft sleeve 37 is connected to the output shaft of the motor 36 so as to rotate relative to the motor 36. One end of the connecting shaft 38 is connected to the second shaft sleeve 31, and the other end is connected to the roller 34. The top of the connecting shaft 38 is sleeved in the second shaft sleeve 31.

[0044] In this embodiment, the rigidity of a real lumbar patient is simulated by providing a motor 36, and the rotation of the lumbar spine during lumbar manipulation is simulated by providing a fourth bushing 37 and a connecting shaft 38.

[0045] In one embodiment of the present invention, the outer sleeve on the top of the connecting shaft 38 is provided with a second spring 39, the second spring 39 is arranged in the second sleeve 31, the inner wall of the second sleeve 31 is provided with a first arc groove 311, the outer wall of the connecting shaft 38 is provided with a second arc groove 381, and an arc key 40 is installed in the second arc groove 381, and the part of the arc key 40 that exceeds the second arc groove 381 is stuck in the first arc groove 311.

[0046] In this embodiment, by setting the second spring 39, the height increase of the roller 34 during the rolling and rising process can be offset, thereby ensuring that only the impact of the arc segment 351 on the roller 34 is finally presented without causing the upward movement of the simulated thoracic vertebrae component 15; by setting the first arc groove 311, the arc key 40 and the second arc groove 381, the torque generated during the rotation process can be effectively transmitted.

[0047] It should be noted that the arc key 40 can be fixed in the first arc groove 311 by using a spring screw, so as to ensure that the portion of the arc key 40 that exceeds the second arc groove 381 is stuck in the first arc groove 311 .

[0048] In one embodiment of the present invention, a first plane structure 312 is provided at the bottom of the second sleeve 31, a second plane structure 371 is provided at the top of the fourth sleeve 37, the first plane structure 312 is attached to and fixed to the second plane structure 371, two rollers 34 are provided, and four groups of arc segments 351 are provided on the upper surface of the chassis 35, each group of arc segments 351 includes two arc segments 351 that are connected to each other and have different curvatures.

[0049] In this embodiment, by setting the first plane structure 312 and the second plane structure 371, the two columnar structures can be better fixed, that is, the contact area between the two is increased, thereby increasing the stability of the two; by setting the number of rollers 34 to two symmetrical ones, and setting four groups of arc segments 351 on the upper surface of the chassis 35, each group of arc segments 351 includes two arc segments 351 that are connected to each other and have different curvatures, so that the real lumbar manipulation can be simulated, that is, the lumbar spine of the lumbar patient can be rotated to the left, and the lumbar spine of the lumbar patient can be rotated to the right.
