[0002] In orthopedic joint replacement surgery, in order to ensure the success rate of the operation and the quality of the patient's recovery, the patient's joints and limbs need to be precisely supported and positioned during the operation. Although traditional auxiliary devices have met the basic needs of the operation to a certain extent, with the continuous development of medical technology and patient needs, these devices have gradually shown many limitations. For example, traditional support devices mostly adopt a fixed design, lack height and angle adjustment functions, and cannot adapt to the individual differences of patients of different body shapes, which may cause patients to feel uncomfortable during the operation and even affect the surgical effect. In addition, traditional equipment has a relatively primitive way of handling waste liquid and residue generated during the operation, usually relying on manual cleaning or a simple drainage system. Such a treatment method is not only inefficient, but also easily causes contamination of the surgical area, increasing the risk of postoperative infection.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] An auxiliary device for orthopedic joint replacement surgery, such as Figure 1-Figure 14 As shown, it includes a bottom frame 1, an upper frame 2 is slidably arranged on the bottom frame 1, a placing table 3 is slidably arranged on the upper frame 2, the top of the placing table 3 is a recessed arc structure, the placing table 3 is used to support the patient's joints, a cushion 4 is installed on the placing table 3, a lifting mechanism 5 is arranged between the bottom frame 1 and the upper frame 2, the lifting mechanism 5 is used to adjust the interval between the bottom frame 1 and the upper frame 2, and a supporting mechanism 6 is rotatably arranged on the right part of the upper frame 2, and the supporting mechanism 6 is used to provide auxiliary support to the patient's limb structures other than the joints.

[0042] It should be noted that when performing orthopedic joint replacement surgery on patients, the device can be used to assist in the operation. First, the support mechanism 6 is adjusted according to the part of the bone joint that needs to be replaced by the patient so that the support mechanism 6 can match the patient's joints and limbs. Then, the height between the upper frame 2 and the bottom frame 1 is adjusted by relying on the lifting mechanism 5. After the adjustment is completed, the patient's limbs can be placed and the surgical operation can be performed normally.

[0043] The lifting mechanism 5 includes a fixed plate 51, which is arranged inside the bottom frame 1, and a rotating member 52 is rotatably connected to the fixed plate 51, and a screw rod 53 is connected to the rotating member 52. The screw rod 53 is rotatably connected to the upper frame 2, and the screw rod 53 is threadedly connected to the fixed plate 51. A worm gear 54 is connected to the rotating member 52, and a worm 55 is rotatably connected to the front of the bottom frame 1. A power-assisting block is arranged at the left end of the worm 55, and the right side of the worm 55 is meshed with the worm gear 54.

[0044] It should be noted that when the height of the placement table 3 needs to be adjusted, the worm gear 54 is directly rotated by rotating the worm 55, so that the worm gear 54 drives the rotating member 52 to rotate, and the rotating member 52 drives the screw rod 53 to rotate and move upward along the fixed plate 51, thereby achieving the effect of adjusting the height of the placement table 3.

[0045] The supporting mechanism 6 includes a first fixed seat 61, and the first fixed seat 61 is connected to the upper right side of the upper frame 2 by bolts. A rotating plate 62 is rotatably connected to the first fixed seat 61, and a plurality of guide grooves are provided on the rotating plate 62. The guide grooves are used to guide and discharge the waste liquid generated during the operation. Fixed columns 63 are connected to the left and right sides of the rear of the upper frame 2, and electric push rods 64 are provided on the fixed columns 63. The telescopic ends of the electric push rods 64 are rotatably connected to the rotating plate 62. Fixed frames 65 are connected to the left and right sides of the rear of the upper frame 2, and the fixed columns 63 and the electric push rods 64 are both located in adjacent fixed frames 65.

[0046] It should be noted that when the patient's joints and limbs need to be supported, the telescopic end of the electric push rod 64 can be controlled to move, so that the rotating plate 62 can be flipped upward along the first fixed seat 61. When the rotating plate 62 is flipped, the electric push rod 64 is closed, and the patient's joints and limbs can be supported by relying on the rotating plate 62.

[0047] Example 2

[0048] It also includes a collecting mechanism 7, which includes a first collecting frame 71. The first collecting frame 71 is rotatably connected to the right side of the placement table 3, and a first driving motor 72 is installed on the rear side of the lower part of the first collecting frame 71. Two crushing rollers 73 are rotatably connected to the lower part of the first collecting frame 71. The crushing rollers 73 are used to crush the residue. A leakage groove is opened on the left part of the first collecting frame 71. Gears 74 are connected to the front ends of the crushing rollers. The two gears 74 are meshed with each other. The crushing roller on the right side is connected to the output shaft of the first driving motor 72. A second collecting frame 75 is connected to the right side of the lower part of the upper frame 2. A second water pipe 78 is connected between the second collecting frame 75 and the first collecting frame 71. A first water pipe 77 is connected between the second collecting frame 75 and the rotating plate 62. A negative pressure port 76 is provided on the second collecting frame 75.

[0049] It should be noted that after the surgical treatment is completed, the debris left after the surgery is poured into the first collection frame 71, and the accumulated fluid is sent into the second collection frame 75 through the second water pipe 78 by relying on the leakage groove, and then the first drive motor 72 is started. The rotation of the output shaft of the first drive motor 72 will drive the crushing roller to rotate, so that the debris is crushed and processed, and then enters the second collection frame 75 through the first water pipe 77. At the same time, the negative pressure port 76 is connected to the negative pressure device, and the negative pressure device is started, so that the accumulated fluid in the rotating plate 62 enters the second collection frame 75 through the first water pipe 77. At the same time, the residue in the first collection frame 71 will also be sucked into the second collection frame 75 due to the negative pressure state to complete the centralized recovery process.

[0050] It also includes a synchronization mechanism 8, which includes a first fixing member 81, two first fixing members 81 are connected to the lower part of the placement table 3, and two second fixing members 82 are connected to the front side of the rotating plate 62. A first connecting member 811 is connected between the first fixing members 81, and a first connecting rod 83 is rotatably connected to the first connecting member 811, a second connecting member 812 is rotatably connected between the second fixing members 82, and a second connecting rod 84 is rotatably connected to the front side of the second connecting member 812. The first connecting rod 83 and the second connecting rod 84 are rotatably connected, and a mounting frame 85 is provided on the second connecting rod 84. A second driving motor 86 is installed on the mounting frame 85, and a rotating disk 87 is connected to the output shaft of the second driving motor 86. A moving member 88 is slidably connected in the mounting frame 85, and the moving member 88 is slidably connected to the rotating disk 87. A latch member 89 is slidably connected to the moving member 88, and the latch member 89 is engaged with the first connecting rod 83, and a first spring 810 is connected between the latch member 89 and the moving member 88.

[0051] It should be noted that, in the initial state, the first connecting rod 83 is locked by the latch member 89. At this time, the first connecting rod 83 and the second connecting rod 84 cannot rotate. At this time, as the rotating plate 62 is unfolded, the second fixing member 82 drives the second connecting member 812, the second connecting member 812 drives the second connecting rod 84, the second connecting rod 84 drives the first connecting rod 83, the first connecting rod 83 drives the first connecting member 811, and the first connecting member 811 drives the first fixing member 81, so that the placement table 3 moves to the right and approaches the rotating plate 62, and the gap between the placement table 3 and the rotating plate 62 is adjusted, thereby bringing a more comfortable experience for the patient to place the limb joints, which is more suitable for patients with shorter limb joints. When you do not want the rotating plate 62 to adjust, it will drive the placement When the table 3 moves, it is necessary to control the output shaft of the second drive motor 86 to rotate, so that the rotating disk 87 drives the moving part 88 to move. The movement of the moving part 88 will push the latch part 89 to move upward, and then the latch part 89 no longer locks the first connecting rod 83. At this time, the first connecting rod 83 and the second connecting rod 84 are restored to a rotating state. When the rotating plate 62 starts to move, the first connecting rod 83 and the second connecting rod 84 are used to prevent the rotating plate 62 from pulling the placement table 3 to produce displacement. Similarly, when the first connecting rod 83 and the second connecting rod 84 need to be locked, it is only necessary to control the output shaft of the second drive motor 86 to rotate, and rely on the action of the first spring 810 to enable the latch part 89 to re-engage with the first connecting rod 83.

[0052] It also includes a placement mechanism 9, which includes a fixed plate 91. The fixed plate 91 is connected to the bottom of the bottom frame 1, and the fixed plate 91 is placed on a chassis 92. A tooth groove is provided on the inner side of the chassis 92. Two sliding members 93 are slidably connected to the fixed plate 91. A second spring 94 is connected between the sliding member 93 and the fixed plate 91, and the sliding member 93 can be engaged with the tooth groove.

[0053] It should be noted that during auxiliary treatment, the bottom frame 1 can be directly rotated as needed, so that the fixed plate 91 can be rotated and adjusted on the bottom plate 92 by relying on the cooperation of the sliding member 93 and the second spring 94, thereby changing the angle of the bottom frame 1, so that medical staff can perform angle adjustment operations more conveniently.

[0054] It also includes a lighting mechanism 10, which includes a second fixed seat 101. The left and right parts of the placement table 3 are connected to the second fixed seat 101. The second fixed seat 101 is rotatably connected to a third connecting rod 102. The third connecting rod 102 is rotatably connected to a fourth connecting rod 103. The fourth connecting rod 103 is rotatably connected to a fifth connecting rod 104. The fifth connecting rod 104 is rotatably connected to a lighting assembly 105.

[0055] It should be noted that during operation, the lighting assembly 105 can be pulled so that the third connecting rod 102, the fourth connecting rod 103 and the fifth connecting rod 104 are all rotated and unfolded, so that the lighting assembly 105 is lifted, and then the lighting assembly 105 is turned on for lighting, thereby providing a better lighting environment.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
