DETAILED DESCRIPTION

[0035] The embodiments of the technical scheme of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0036] Please refer to Figures 1 to 3 The present application provides a small animal knee joint disease demonstration system, which comprises a base 100, a guide frame 200, a movable block 300, a leg skeleton model 400, an angle adjusting piece 500 and a patellar tendon model 600.

[0037] Specifically, the guide frame 200 is vertically arranged on the base 100. The movable block 300 is arranged on the guide frame 200 and can slide up and down along the guide frame 200. The leg skeleton model 400 comprises a femur model 410, a tibia model 420 and a patella model 430. The knee end of the femur model 410 is hingedly connected with the tibia model 420. The other end of the tibia model 420 is hingedly connected with the bottom end of the guide frame 200. The top end of the femur model 410 is hingedly connected with the movable block 300. A recess is formed in the knee end of the femur model 410.

[0038] The angle adjusting member 500 is coaxially arranged on the top of the femur model 410 and can rotate. The two ends of the patella model 430 are provided with the patellar tendon model 600. The ends of the two patellar tendon models 600 are connected with the angle adjusting member 500 and the other ends are connected with the tibia model 420. The patella model 430 can slide in the groove. In the specific implementation, the depth of the groove can accommodate the patella model 430.

[0039] In use, when the movable block 300 is manually slid downward, the knee bending action can be performed. After the movable block 300 is released, the femur model 410 and the tibia model 420 can complete the leg stretching action under the action of the patellar tendon model 600.

[0040] In use, when communicating with the animal owner or teaching, the demonstration system can be used for explanation. During the explanation, the movable block 300 can be manually driven to move up and down along the guide frame 200. After the knee is bent, the leg skeleton model 400 is released, and then the leg stretching action can be completed under the action of the patellar tendon model 600.

[0041] When the whole knee joint is normal, the connection positions of the two ends of the patellar tendon model 600 and the groove are located on a straight line, and the patella model 430 is located in the groove. During the knee bending and leg stretching action, the patellar tendon model 600 keeps tracking the patella model 430.

[0042] When the femur model 410 is laterally bent, the patella model 430 slides out of the groove, and then the patella model 430 is dislocated. During the demonstration, the patella model 430 can be pulled out of or into the groove by rotating the angle adjusting member 500 and pulling the patellar tendon model 600, so as to simulate the dislocation of the patella model 430. The degree of dislocation of the patella model 430 is divided into first degree dislocation, second degree dislocation, third degree dislocation and fourth degree dislocation according to the severity of the disease. The first degree dislocation and the second degree dislocation can be reset to the groove under the action of external force, and the third degree dislocation and the fourth degree dislocation are the non-reset conditions.

[0043] When the patella model 430 slides out of the groove to the lateral side of the knee joint, the patella model 430 is laterally dislocated. When the patella model 430 slides out of the groove to the medial side of the knee joint, the patella model 430 is medially dislocated. When the patella model 430 is dislocated, the knee no longer has a strong extension mechanism, and the leg is often very weak and almost collapses. At the same time, when the patella model 430 rubs back and forth in this abnormal position, the cartilage is worn, leading to chronic pain and knee arthritis. At the same time, when the knee part is not supported by the patella model 430, other ligaments (such as the anterior cruciate ligament) of the knee are subjected to abnormal pressure and can be subjected to secondary injury.

[0044] As a preferred embodiment, the system further comprises a pair of elastic collateral ligament models 700, the knee end of the femur model 410 and the knee end of the tibia model 420 are connected with the collateral ligament models 700 on the medial and lateral sides. With the assistance of the two collateral ligament models 700, the leg skeleton model 400 can further facilitate the leg stretching action.

[0045] As another preferred embodiment, the system further comprises a long toe extensor tendon model 800, the lateral side of the knee end of the tibia model 420 is transversely and spacedly provided with two outwardly protruding nodules, the long toe extensor tendon model 800 is connected at one end with the knee end of the femur model 410 and at the other end with the tibia model 420 after passing through the gap between the two nodules.

[0046] With the long toe extensor tendon model 800, the stability of the knee bending and stretching actions of the femur model 410 and the tibia model 420 can be further improved.

[0047] In specific implementation, the leg skeleton model 400 can be provided in two, and the two leg skeleton models 400 are arranged on the left and right sides of the guide frame 200. When in use, the two leg skeleton models 400 of one system can demonstrate different disease conditions of the two legs.

[0048] Research shows that when the femur model 410 is bent to cause the patella model 430 to dislocate, since the risk of straightening the femur model 410 is high, this method is rarely used in medicine, and generally, the depth of the groove can be changed to treat the patella model 430 dislocation,

[0049] In order to facilitate demonstration, the femur model 410 of one of the leg skeleton models 400 of the small animal knee joint disease demonstration system comprises a first femur body model 411, a gliding cartilage model 412, and a trochlear groove deepening piece 413, the knee end of the first femur body model 411 is provided with a deepening groove, the trochlear groove deepening piece 413 is detachably clamped in the deepening groove, and the gliding cartilage model 412 is clamped on the trochlear groove deepening piece 413, and the gliding cartilage model 412 and the side wall of the deepening groove form a groove.

[0050] In communication or surgical plan scheduling, by clamping the trochlear groove deepening piece 413 with different thicknesses, the dislocation of the patella model 430 when the groove with different depths is simulated, a reasonable groove depth is obtained, a reasonable reference value for surgery is provided, and the surgical effect can be improved.

[0051] Meanwhile, without straightening the femur model 410, the connection point of the patellar tendon model 600 and the tibia model 420 can be adjusted to ensure that the connection points at both ends of the patellar tendon model 600 and the groove are automatically located on a straight line, and the dislocation probability is reduced.

[0052] Specifically, the other femur model 410 comprises a second femur body model 414 and a trochlear groove replacement block 415, the trochlear groove replacement block 415 is detachably arranged at the knee end of the second femur body model 414, and a groove is arranged on the trochlear groove replacement block 415.

[0053] In the embodiment, the tibia model 420 comprises a tibia body model 421 and a tibial tuberosity transfer block model 422, the tibial tuberosity transfer block model 422 is rotatably arranged at the knee end of the tibia model 421, and the patellar tendon model 600 is connected with the tibial tuberosity transfer block model 422.

[0054] During demonstration, the connection positions of the two ends of the patellar tendon model 600 can be automatically arranged on a straight line with the groove by rotating the tibial tuberosity transfer block model 422, so that the dislocation probability is reduced.

[0055] By using the demonstration system, the structure and disease causes of the knee joint can be conveniently explained, and the treatment scheme can be conveniently exchanged, so that the treatment effect is improved.

[0056] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and all of them should be covered in the scope of the claims and the specification of the present application.
