[0042] like Figures 1 to 3As shown, an embodiment of the present invention provides a prosthesis implant measurement mechanism for shoulder joint replacement surgery, including a mounting box 1, a driving component 7, a fixing component 8 and an auxiliary component 9, wherein a slot 10 is provided at one end of the mounting box 1, a mounting rod 2 is provided at one side of the mounting box 1, a collar 3 is provided at one end of the mounting rod 2, a mounting plate 4 is provided at one end of the mounting box 1, a top side of the mounting plate 4 is connected to the outer surface of the collar 3, a telescopic rod 5 is provided at one side of the mounting box 1, and a mounting ring 6 is sleeved at the top of the telescopic rod 5; a driving component 7 is provided at the edge of one side of the mounting box 1, and the driving component 7 is used to drive the fixing component 8 and the auxiliary component 9; a fixing component is provided in the internal cavity of the mounting box 1 8. The fixing component 8 is used to fix the patient's arm; an auxiliary component 9 is arranged on the top of the installation box 1. The auxiliary component 9 is used to assist in the implantation of the prosthesis. By setting the driving component 7, the graded processing of "auxiliary fixation-auxiliary positioning" is realized. At the same time, the medical staff can switch between functions with one hand. The fixing component 8 is set to achieve auxiliary fixation of the patient's shoulder and arm, and improve the stability between the auxiliary component 9 and the patient's arm when the shoulder joint prosthesis is implanted. By setting the auxiliary component 9, the auxiliary ring 94 is prevented from changing its angle for the second time during the implantation operation to affect the implantation angle of the shoulder joint prosthesis, thereby further ensuring the implantation accuracy of the shoulder joint prosthesis during the implantation operation.

[0043] like Figure 4 , Figure 6 and Figure 7 As shown, the driving assembly 7 includes an arc-shaped slide rail 71, which is arranged on one side of the installation box 1. A sliding base 72 is arranged on the inner wall of the arc-shaped slide rail 71. A telescopic rod 2 73 is arranged at one end of the sliding base 72. One end of the telescopic rod 2 73 is arranged on one side of the inner wall of the arc-shaped slide rail 71. The telescopic rod 2 73 is damping-connected to one side of the inner wall of the arc-shaped slide rail 71. A turntable 74 is nested at the center of the top end of the sliding base 72, and a flat gear 1 75 is connected to the bottom end of the turntable 74.

[0044] In this embodiment, the medical staff first cleans the patient's shoulder joint and removes the broken bones. Then, the medical staff places the device on the patient's shoulder joint through the handle at the top of the mounting plate 4, and puts the ring 3 on the patient's shoulder. The ring 3 makes one end of the mounting box 1 fit the patient's arm skin through the mounting rod 2. Then, the user pushes the turntable 74 along the direction of the arc-shaped slide rail 71. While the turntable 74 is forced to slide, it drives the sliding base 72 at the bottom to slide synchronously. While the sliding base 72 slides, it pulls one end of the telescopic rod 2 73. The turntable 74 drives the flat gear 1 75 at the bottom to gradually approach and mesh with the flat gear 2 81. Under the action of the damping connection between the telescopic rod 2 73 and the inner wall of the arc-shaped slide rail 71, the flat gear 1 75 and the flat gear 2 81 remain in meshing state. At this time, the medical staff rotates the turntable 74, and the rotation of the turntable 74 drives the flat gear 1 75 to engage the flat gear 2 81 to rotate. Similarly, when the rotation angle of the auxiliary ring 94 is adjusted to the right position, the medical staff pushes the turntable 74 in the opposite direction, and the turntable 74 slides under the force, driving the sliding base 72 at the bottom to slide synchronously. The sliding base 72 slides and squeezes one end of the telescopic rod 2 73. The turntable 74 drives the flat gear 1 75 at the bottom to gradually approach and engage the flat gear 4 91. Under the action of the damping connection between the telescopic rod 2 73 and the inner wall of the arc-shaped slide rail 71, the flat gear 1 75 and the flat gear 4 91 remain in a meshing state. Then the medical staff rotates the turntable 74 to drive the flat gear 1 75 to rotate synchronously. The flat gear 1 75 rotates and engages the flat gear 4 91 to rotate.

[0045] By setting a damping connection between the sliding base 72 and the telescopic rod 2 73, the turntable 74 is used to drive the flat gear 1 75 to rotate, thereby driving the fixing component 8 and the auxiliary component 9 to operate respectively, thereby realizing the graded processing of "auxiliary fixation-auxiliary positioning", improving the convenience of height adjustment operation in shoulder replacement surgery, avoiding excessive operation steps that affect the operation efficiency during surgery, and having a simple structure, which is easy to maintain after the surgery.

[0046] like Figure 5 to Figure 6As shown, the fixing assembly 8 includes a flat gear 81, which is arranged at the top of the inner wall of the installation box 1, and an arc-shaped toothed ring 82 is meshed on one side of the flat gear 81. The number of arc-shaped toothed rings 82 is set in two groups, and an arc-shaped fixing block 83 is arranged at one end of the arc-shaped toothed ring 82. A rubber pad 84 is arranged on the outer surface of one side of the arc-shaped fixing block 83. An arc-shaped slider 85 is arranged at one end of the arc-shaped fixing block 83. The outer surface of the arc-shaped slider 85 contacts the inner wall of the slot 10. The arc-shaped slider 85 is arranged at one end of the arc-shaped fixing block 83. The number is set to two groups, and the two groups of arc-shaped sliding blocks 85 are relatively arranged at the two ends of the arc-shaped fixed block 83. A bevel gear group 86 is arranged at the bottom end of the flat gear 2 81, and the bottom end of the bevel gear group 86 is arranged at the bottom end of the inner wall of the installation box 1. A rotating rod 87 is arranged at one end of the bevel gear group 86. The number of the bevel gear groups 86 is set to two groups, and the two groups of bevel gear groups 86 are connected by the rotating rod 87. A flat gear three 88 is arranged at the bottom end of the other group of bevel gear groups 86, and one side of the flat gear three 88 is meshed with the arc-shaped gear ring 82.

[0047] In this embodiment, the flat gear 81 rotates and meshes with the arc-shaped toothed ring 82 on one side. Under the rotation of the flat gear 81, the arc-shaped toothed ring 82 drives the arc-shaped fixed block 83 at one end to slide in the internal cavity of the installation box 1, so that the arc-shaped fixed block 83 slides and extends along the slot 10 at one end of the installation box 1 through the arc-shaped slider 85. When the arc-shaped fixed block 83 slides, it drives the rubber pad 84 to slide, so that the rubber pad 84 contacts and fits the patient's arm skin;

[0048] When the flat gear 2 81 rotates, it also drives the input end of the bevel gear set 86 at the bottom to rotate synchronously. When the input end of the bevel gear set 86 rotates, it engages with the output end of the bevel gear set 86 to rotate synchronously. When the output end of the bevel gear set 86 rotates, it drives the input end of another bevel gear set 86 to rotate synchronously through the rotating rod 87. When the input end of another bevel gear set 86 rotates, it engages with the output end to rotate synchronously. When the output end of another bevel gear set 86 rotates, it drives the flat gear 3 88 at the bottom to rotate synchronously. When the flat gear 3 88 rotates, it engages with another group of arc gear rings 82. Similarly, the arc gear ring 82 drives the arc fixing block 83 to slide and extend along the slot 10 at one end of the mounting box 1. The patient's arm is fixed by the sliding extension of the two groups of arc fixing blocks 83.

[0049] like Figures 7 to 9As shown, the auxiliary component 9 includes a flat gear 91, which is arranged on one side of the installation box 1. A screw 92 is arranged on the top of the flat gear 91. The top of the screw 92 is connected to the bottom of the installation plate 4. A sliding seat 93 is provided on the outer surface of the screw 92. An auxiliary ring 94 is arranged at one end of the sliding seat 93. The outer surface of one end of the auxiliary ring 94 contacts the inner wall of the installation ring 6. A transmission rod 95 is arranged at one end of the auxiliary ring 94. A turning handle 950 is arranged at one end of the transmission rod 95. The face sleeve is provided with an angle disk 951, a convex ring 96 is provided on the surface of one end of the transmission rod 95, a limiting ring 97 is provided on one side of the mounting ring 6, a threaded base 98 is provided on the inner wall of the limiting ring 97, a retaining ring 99 is provided on one end of the threaded base 98, a screw rod 2 910 is provided on the threaded sleeve of the inner wall of the threaded base 98, the screw rod 2 910 is arranged on one side of the limiting ring 97, a flat gear 5 911 is provided on one end of the screw rod 2 910, a rack 912 is meshed with one end of the flat gear 5 911, and the rack 912 is arranged on one side of the mounting box 1.

[0050] In this embodiment, after the two sets of arc-shaped fixing blocks 83 are fixed in place on the patient's arm, the medical staff then rotates the handle 950, and the handle 950 drives the auxiliary ring 94 to rotate through the transmission rod 95, so that the rotation angle of the auxiliary ring 94 is consistent with the angle of the humeral head shaft at 30 degrees to 50 degrees. The medical staff can adjust the rotation angle in real time by observing the angle plate 951;

[0051] When the rotation angle of the auxiliary ring 94 is adjusted to the right position, the medical staff pushes the turntable 74 in the opposite direction, and the turntable 74 slides under the force, driving the sliding base 72 at the bottom to slide synchronously. While the sliding base 72 slides, it squeezes one end of the telescopic rod 2 73, and the turntable 74 drives the flat gear 1 75 at the bottom to gradually approach and mesh with the flat gear 4 91. Under the action of the damping connection between the telescopic rod 2 73 and the inner wall of the arc-shaped slide rail 71, the flat gear 1 75 and the flat gear 4 91 are kept in meshing state. Then the medical staff rotates the turntable 74 to drive the flat gear 1 75 to rotate synchronously. While the flat gear 1 75 rotates, it meshes with the flat gear 4 91 to rotate.

[0052] The rotation of the flat gear 4 91 drives the screw 1 92 to rotate synchronously. When the screw 1 92 rotates, the sliding seat 93 sleeved on the outer surface of the screw 1 92 slides downward. When the sliding seat 93 slides, it drives the auxiliary ring 94 and the transmission rod 95 to slide downward synchronously. When the transmission rod 95 slides, it drives the mounting ring 6 to slide and squeeze the telescopic rod 1 5. When the mounting ring 6 slides downward, it drives the flat gear 5 911 to slide synchronously. When the flat gear 5 911 slides, it meshes with the rack 912 to rotate. When the flat gear 5 911 rotates, it drives The screw rod 910 rotates synchronously, and the screw rod 910 rotates while causing the threaded base 98 sleeved on the outer surface of the screw rod 910 to slide. The threaded base 98 slides on the inner wall of the limiting ring 97 while driving the retaining ring 99 to approach the convex ring 96. The retaining ring 99 limits the convex ring 96 to prevent the transmission rod 95 from driving the auxiliary ring 94 to rotate during implantation, thereby changing the angle of the auxiliary ring 94 and causing an error in the implantation angle. When the auxiliary ring 94 slides into place, medical staff can use the auxiliary ring 94 to assist in positioning the prosthesis during implantation.

[0053] By setting the coordination between the auxiliary ring 94, the transmission rod 95 and the angle plate 951, the angle of the auxiliary ring 94 is pre-adjusted before the shoulder joint prosthesis is implanted, so that the rotation angle of the auxiliary ring 94 and the angle of the humeral head are consistent, thereby improving the implantation accuracy of the shoulder joint prosthesis during the implantation operation. Through the connection effect between the threaded base 98 and the screw rod 910, the driving clamping ring 99 and the convex ring 96 are clamped together, so that the convex ring 96 can limit the transmission rod 95 and the auxiliary ring 94, thereby preventing the auxiliary ring 94 from changing its angle for a second time during the implantation operation and affecting the implantation angle of the shoulder joint prosthesis.

[0054] The working process of the technical solution provided by the present invention is as follows:

[0055] The medical staff first cleans the patient's shoulder joint and removes broken bones. Then, the medical staff places the device on the patient's shoulder joint through the handle at the top of the mounting plate 4, and puts the ring 3 on the patient's shoulder. The ring 3 makes one end of the mounting box 1 fit the patient's arm skin through the mounting rod 2.

[0056] The user then pushes the turntable 74 along the arc slide rail 71. The turntable 74 slides under the force and drives the sliding base 72 at the bottom to slide synchronously. The sliding base 72 slides and pulls one end of the telescopic rod 2 73. The turntable 74 drives the flat gear 1 75 at the bottom to gradually approach and engage with the flat gear 2 81. Under the action of the damping connection between the telescopic rod 2 73 and the inner wall of the arc slide rail 71, the flat gear 1 75 and the flat gear 2 81 remain in a meshing state. At this time, the medical staff rotates the turntable 74, and the rotation of the turntable 74 drives the flat gear 1 75 to engage with the flat gear 2 81 and rotate.

[0057] As the flat gear 81 rotates, it engages with the arc-shaped toothed ring 82 on one side. Under the rotation of the flat gear 81, the arc-shaped toothed ring 82 drives the arc-shaped fixed block 83 at one end to slide in the internal cavity of the installation box 1, so that the arc-shaped fixed block 83 slides and extends along the slot 10 at one end of the installation box 1 through the arc-shaped slider 85. When the arc-shaped fixed block 83 slides, it drives the rubber pad 84 to slide, so that the rubber pad 84 contacts and fits the patient's arm skin.

[0058] When the flat gear 2 81 rotates, it synchronously drives the input end of the bevel gear set 86 at the bottom to rotate synchronously. When the input end of the bevel gear set 86 rotates, it engages with the output end of the bevel gear set 86 to rotate synchronously. When the output end of the bevel gear set 86 rotates, it drives the input end of another group of bevel gear sets 86 to rotate synchronously through the rotating rod 87. When the input end of another group of bevel gear sets 86 rotates, it engages with the output end to rotate synchronously. When the output end of another group of bevel gear sets 86 rotates, it drives the flat gear 3 88 at the bottom to rotate synchronously. When the flat gear 3 88 rotates, it engages with another group of arc gear rings 82. Similarly, the arc gear ring 82 drives the arc fixing block 83 to slide and extend along the slot 10 at one end of the mounting box 1. The patient's arm is fixed by the sliding extension of the two groups of arc fixing blocks 83.

[0059] When the two sets of arc-shaped fixing blocks 83 are fixed in place on the patient's arm, the medical staff then turns the handle 950, and the handle 950 drives the auxiliary ring 94 to rotate through the transmission rod 95, so that the rotation angle of the auxiliary ring 94 is consistent with the angle of the humeral head shaft at 30 degrees to 50 degrees. The medical staff can adjust the rotation angle in real time by observing the angle disk 951.

[0060] When the rotation angle of the auxiliary ring 94 is adjusted to the right position, the medical staff pushes the turntable 74 in the opposite direction. The turntable 74 slides under the force, driving the sliding base 72 at the bottom to slide synchronously. The sliding base 72 slides while squeezing one end of the telescopic rod 2 73. The turntable 74 drives the flat gear 1 75 at the bottom to gradually approach and mesh with the flat gear 4 91. Under the action of the damping connection between the telescopic rod 2 73 and the inner wall of the arc-shaped slide rail 71, the flat gear 1 75 and the flat gear 4 91 remain in a meshing state. Then the medical staff rotates the turntable 74 to drive the flat gear 1 75 to rotate synchronously. The flat gear 1 75 rotates while meshing with the flat gear 4 91 to rotate.

[0061] When the flat gear 4 91 rotates, it drives the screw 1 92 to rotate synchronously. When the screw 1 92 rotates, the sliding seat 93 sleeved on the outer surface of the screw 1 92 slides downward. When the sliding seat 93 slides, it drives the auxiliary ring 94 and the transmission rod 95 to slide downward synchronously. When the transmission rod 95 slides, it drives the mounting ring 6 to slide and squeeze the telescopic rod 1 5. When the mounting ring 6 slides downward, it drives the flat gear 5 911 to slide synchronously. When the flat gear 5 911 slides, it meshes with the rack 912 to rotate. When the flat gear 5 911 rotates, it drives The screw rod 910 rotates synchronously, and the screw rod 910 rotates while causing the threaded base 98 sleeved on the outer surface of the screw rod 910 to slide. The threaded base 98 slides on the inner wall of the limiting ring 97 while driving the retaining ring 99 to approach the convex ring 96. The retaining ring 99 limits the convex ring 96 to prevent the transmission rod 95 from driving the auxiliary ring 94 to rotate during implantation, thereby changing the angle of the auxiliary ring 94 and causing an error in the implantation angle. When the auxiliary ring 94 slides into place, medical staff can use the auxiliary ring 94 to assist in positioning the prosthesis during implantation.
