Technical Field

[0001] The present invention relates to the technical field of medical orthopedic simulation devices, and particularly relates to a hip arthroscopic surgery simulation device for orthopedics. Background Art

[0002] The orthopedic hip arthroscopic surgery simulation device is an important training tool for improving doctors' surgical skills, and its core function needs to highly reproduce the anatomical structure and dynamic operation scenario of the human hip joint. However, the clamping devices in the prior art have significant deficiencies in flexibility and multi-directional adjustment capabilities, restricting the authenticity of surgical simulation and the training effect.

[0003] For example, an orthopedic hip arthroscopic surgery simulation device with the publication number CN113140146A belongs to the technical field of simulation devices. An orthopedic hip arthroscopic surgery simulation device includes an experimental table and a hip joint model. One end of the hip joint model is fixedly connected with a second fixing block, and further includes: a first mounting plate fixedly connected to the experimental table; a second mounting plate slidably connected to the experimental table; a fixing frame rotatably connected to the first mounting plate, wherein one end of the hip joint model is placed in the fixing frame; the present invention quickly clamps and fixes the hip joint model through the fixing frame and the clamping assembly; by rotating the turning handle, the clamping assembly rotates, driving the hip joint model to rotate, thereby improving the flexibility of the device and enabling multi-directional observation of the hip joint model.

[0004] This device mainly drives the clamping assembly to rotate around a single axis through the turning handle, lacking the ability of multi-directional coordinated adjustment and unable to simulate some normal movement trajectories of the hip joint, resulting in insufficient flexibility and authenticity of surgical simulation.

[0009] Preferably, the two transverse movement assemblies include two U-shaped frames fixedly arranged on one support plate and one end of the fixed shaft. A chute is formed on the inner wall of one side of the U-shaped frame. Two clamping boxes are arranged inside the U-shaped frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Place the two sides of the femur model and the pelvis model into the lateral movement assemblies on both sides respectively. By turning the handle rods on both sides to drive the third threaded rod to rotate, while the third threaded rod in threaded connection moves downward, it pushes the upper clamping box to slide downward along the chute through the slider, so that the two clamping boxes approach each other, thereby clamping one end of the femur model or the pelvis model. The several positioning rods arranged inside the clamping box can change correspondingly according to the shapes of the femur model and the pelvis model, shrink to the inside of the circular groove and squeeze the clamping spring, so that the clamped side fits the surface of the model. Compared with the existing planar clamping, this fixture is more suitable for the shapes of different models and can clamp and stabilize them more effectively.

[0017] 2. By turning the positioning bolt and screwing the positioning bolt out of the corresponding positioning hole to release the restriction on the movable plate, and cooperating with the use of the two universal wheels, the movable plate can be rotated along the position of the circular opening, thereby driving the clamped pelvis model on the upper side to rotate back and forth along the connection part of the femur model to simulate the lateral movement under normal conditions. After the positioning bolt is screwed into the positioning hole, the rotated femur model and pelvis model can be observed and operated.

[0018] 3. Rotate the handwheel to drive the rotation of the threaded sleeve connected by threads, so that the threaded sleeve releases the restriction on the support plate, thereby driving the first threaded rod and the connected transverse movement assembly to be adjusted up and down along the adjustment opening. After moving to a suitable position, it adapts to different clamping heights of the pelvic model, and can drive the transverse movement assembly to rotate and fix at different angles. Then reverse the handwheel to press the threaded sleeve against one end of the support plate for fixation. In addition, loosen the positioning sleeve on the second threaded rod to release the positioning of the fixed shaft and the second threaded rod, so as to realize that the fixed shaft drives a set of connected transverse movement assemblies to slide up and down along the arc-shaped slide rail, simulating the longitudinal movement under normal conditions, improving the movement trajectory in different spaces, making the operation simulation more flexible and real, so as to improve the operation ability of doctors during surgery.

Support plates 28 are fixedly installed on the upper ends of the right-angled platform 21 and the movable plate 24 respectively on the sides away from the circular opening 22. An adjustment opening 29 is opened at the middle position of one of the two groups of support plates 28 located on the movable plate 24.

[0030] The connecting shaft 23 is located directly below the connection between the femur model 5 and the pelvis model 6. The movable plate 24 rotates along the circular opening 22 through the connecting shaft 23. The positioning bolt 26 is in threaded connection with the right-angle platform 21. A number of groups of positioning holes 25 are arranged circularly and evenly around the connecting shaft 23. The bottom of the positioning bolt 26 is adapted to the positioning hole 25. One end of one of the two groups of support plates 28 located on the upper side of the right-angle platform 21 is fixedly provided with a set of lateral movement components 4.

[0031] By rotating the positioning bolt 26 and screwing the positioning bolt 26 out of the corresponding positioning hole 25 to release the restriction on the movable plate 24, and in cooperation with the use of the two sets of universal wheels 27, the movable plate 24 can be rotated along the position of the circular opening 22, thereby driving the pelvis model 6 clamped on the upper side to rotate front and back along the connection of the femur model 5, simulating the lateral movement under normal conditions. After the positioning bolt 26 is screwed into the positioning hole 25, the rotated femur model 5 and pelvis model 6 can be observed and operated.

[0032] The longitudinal movement component 3 includes a first threaded rod 31 movably arranged inside the upper side of the adjustment opening 29. A threaded sleeve 32 is movably sleeved on the outer side of the first threaded rod 31. Limit rings 33 are respectively fixedly arranged on the outer sides of the first threaded rod 31 and the threaded sleeve 32. A return spring 34 is arranged between one of the two limit rings 33 and one end of the support plate 28. A handwheel 35 is fixedly arranged at a position close to one side edge of the outer side of the threaded sleeve 32. One end of the first threaded rod 31 is fixedly provided with an arc-shaped slide rail 36. An activity groove 37 is opened inside the arc-shaped slide rail 36.

[0033] The threaded sleeve 32 is in threaded connection with the first threaded rod 31. The two limit rings 33 are respectively arranged at both ends of one of the support plates 28. The return spring 34 is sleeved on the outer side of the first threaded rod 31 and is in a compressed state. The arc center point of the arc-shaped slide rail 36 is set as the connection between the lateral movement component 4 and the femur model 5. The second threaded rod 38 and the fixed shaft 310 are slidably arranged inside the activity groove 37. The two positioning sleeves 39 are in threaded connection with the second threaded rod 38 and are attached to both ends of the arc-shaped slide rail 36. One end of the fixed shaft 310 is fixedly provided with another U-shaped frame 41.

[0034] By rotating the handwheel 35, the threaded sleeve 32 connected by threads is driven to rotate, so that the restriction of the threaded sleeve 32 on the support plate 28 is released. Thus, the first threaded rod 31 and the connected lateral movement assembly 4 can be driven to adjust up and down along the adjustment opening 29. After moving to a suitable position, it adapts to the different clamping heights of the pelvic model 6 and can drive the lateral movement assembly 4 to rotate and fix at different angles. Then, reverse the handwheel 35 to press the threaded sleeve 32 against one end of the support plate 28 for fixation. In addition, by loosening the positioning sleeve 39 on the second threaded rod 38, the positioning of the fixed shaft 310 and the second threaded rod 38 is released, so that the fixed shaft 310 drives a set of connected lateral movement assemblies 4 to slide up and down along the arc-shaped slide rail 36, simulating the longitudinal movement under normal conditions, improving the movement trajectory in different spaces, making the operation simulation more flexible and real, so as to improve the operation ability of doctors during surgery.

[0035] The two sets of lateral movement assemblies 4 include two U-shaped frames 41 fixedly arranged on a set of support plates 28 and one end of the fixed shaft 310. A chute 42 is opened on the inner wall of one side of the U-shaped frame 41. Two clamping boxes 43 are arranged inside the U-shaped frame 41. A plurality of circular grooves 44 are opened on the inner side of the upper set of the two clamping boxes 43. A positioning rod 45 is movably arranged inside each of the plurality of circular grooves 44. A clamping spring 46 is fixedly arranged between the positioning rod 45 and the inner wall of the upper side of the circular groove 44. A slider 47 is fixedly arranged at one end of the clamping box 43 corresponding to the position of the chute 42. A connecting sleeve 48 is fixedly arranged at the upper end of the clamping box 43. A third threaded rod 49 is rotatably arranged inside the connecting sleeve 48. A handle rod 410 is fixedly arranged on the upper side of the third threaded rod 49.

[0036] The lower set of the two clamping boxes 43 is fixedly connected to the U-shaped frame 41. The lower parts of a plurality of positioning rods 45 protrude outside the circular grooves 44. The plurality of positioning rods 45 are arranged in a rectangular array. The slider 47 is slidably arranged inside the chute 42. The third threaded rod 49 is threadedly connected to the upper side of the U-shaped frame 41.

[0037] Put the two sides of the femur model 5 and the pelvic model 6 into the two sets of lateral movement assemblies 4 on both sides respectively. By turning the handle rods 410 on both sides to drive the third threaded rod 49 to rotate, while the third threaded rod 49 connected by threads moves downward, it pushes the upper clamping box 43 to slide downward along the chute 42 through the slider 47, so that the two clamping boxes 43 approach each other, thereby clamping one end of the femur model 5 or the pelvic model 6. And a plurality of positioning rods 45 arranged inside the clamping box 43 can change correspondingly according to the shapes of the femur model 5 and the pelvic model 6, shrink into the inner side of the circular groove 44 to squeeze the clamping spring 46, so that the clamped side adapts to the surface of the model. Compared with the existing planar clamping, this fixture is more suitable for the shapes of different models and can clamp and stabilize them more effectively.

[0038] Working principle: When in use, the two sides of the femur model 5 and the pelvis model 6 are respectively placed into the two lateral movement components 4. By turning the handle rods 410 on both sides, the third threaded rod 49 rotates. While the third threaded rod 49 connected by threads moves downward, it pushes the upper clamping box 43 to slide downward along the chute 42 through the slider 47, causing the two clamping boxes 43 to approach each other, thereby clamping one end of the femur model 5 or the pelvis model 6. A number of positioning rods 45 arranged inside the clamping box 43 can change correspondingly according to the shapes of the femur model 5 and the pelvis model 6, shrink into the inner side of the circular groove 44 and squeeze the clamping spring 46, so that the clamped side adapts to the surface of the model. Compared with the existing planar clamping, this fixture is more suitable for the shapes of different models and can clamp and stabilize them more effectively. Additionally, by turning the positioning bolt 26 and screwing the positioning bolt 26 out of the corresponding positioning hole 25, the restriction on the movable plate 24 is released. With the use of the two universal wheels 27, the movable plate 24 can be rotated along the position of the circular opening 22, thereby driving the pelvis model 6 clamped on the upper side to rotate back and forth along the connection of the femur model 5 to simulate the lateral movement under normal circumstances. After the positioning bolt 26 is screwed into the positioning hole 25, the femur model 5 and the pelvis model 6 after rotation can be observed and operated. Secondly, by turning the handwheel 35 to drive the rotation of the threaded sleeve 32 connected by threads, the threaded sleeve 32 releases the restriction on the support plate 28, so that the first threaded rod 31 and the connected lateral movement component 4 can be adjusted up and down along the adjustment opening 29, move to a suitable position, adapt to the different clamping heights of the pelvis model 6, and can drive the lateral movement component 4 to rotate and fix at different angles. Then, by reversing the handwheel 35, the threaded sleeve 32 is pressed against one end of the support plate 28 for fixation. Additionally, by loosening the positioning sleeve 39 on the second threaded rod 38, the positioning of the fixed shaft 310 and the second threaded rod 38 is released, so that the fixed shaft 310 drives a set of connected lateral movement components 4 to slide up and down along the arc-shaped slide rail 36 to simulate the longitudinal movement under normal circumstances, improve the movement trajectory in different spaces, and make the operation simulation more flexible and realistic to improve the operation ability of doctors during surgery.
