Open osteotomy with support measurement device

Abstract

The application discloses an open osteotomy support measuring device, which can accurately ensure the distance and angle of the osteotomy gap, thereby ensuring the final steel plate fixing accuracy. In specific use, the device is directly embedded into the gap at the osteotomy site, then the second sliding block is driven to slide on the second sliding rail through the driving component, so as to drive the first sliding block to move on the first sliding rail, thereby increasing the angle of the second support plate relative to the first support plate, so that the first support plate and the second support plate abut the two side bone walls of the gap respectively, preventing the two side bones of the osteotomy site from approaching each other, thereby ensuring that the size and angle of the osteotomy gap remain stable at all times, thereby improving the final steel plate fixing accuracy. After the steel plate is fixed, the second sliding block is reversely driven to slide through the driving component, so as to reduce the angle of the second support plate relative to the first support plate, and the device can be taken out from the gap at the osteotomy site.

Description

Technical Field

[0001] This invention relates to the field of orthopedic medical technology, and in particular to a support and measuring device for open osteotomy. Background Technology

[0002] Knee osteoarthritis is a degenerative joint disease in the elderly that begins with the wear and tear of the knee cartilage. It has a high incidence rate and significant social impact. The natural course of knee osteoarthritis is anteromedial osteoarthritis, which can affect all compartments of the knee joint in its middle and late stages, leading to severe pain, deformity, and limited mobility, significantly impacting patients' quality of life. Knee osteoarthritis is often accompanied by varus deformity of the lower limb, and this varus deformity gradually worsens as the knee joint wears down.

[0003] Treatment for early to mid-stage anteromedial knee osteoarthritis often involves high tibial osteotomy (HTO), which involves an open wedge osteotomy at the high tibial level, followed by dislocation at the osteotomy line to correct lower limb alignment and reduce load on the medial compartment. Precise dislocation distance and alignment correction are crucial for surgical efficacy. After the tibial osteotomy and dislocation, a plate is required for fixation.

[0004] Currently, during surgery, surgeons use X-ray fluoroscopy combined with a force line bar to determine the degree of force line correction. This is not only time-consuming and labor-intensive, increasing the risk of infection and the radiation exposure of surgeons, but also has a large margin of error, making it difficult to guarantee accurate force line correction, which in turn affects the surgical outcome.

[0033] This invention proposes a support and measurement device for open osteotomy.

[0034] Please refer to the attached document. Figure 1 - Appendix Figure 5 In one embodiment of the open osteotomy support and measuring device proposed in this invention, the open osteotomy support and measuring device includes a first support plate 110, a second support plate 120, a first slide rail 180, a first slider 190, a second slider 220, a second slide rail 230, a connecting rod 210, and a driving component; the second support plate 120 is hinged to the first support plate 110; the first slide rail 180 is disposed on the side of the second support plate 120 facing the first support plate 110; the first slide rail 180 is perpendicular to the rotation axis of the second support plate 120, and the extending direction of the first slide rail 180 is parallel to the second support plate 120; The first slider 190 is slidably disposed on the first slide rail 180; the second slide rail 230 is disposed on the side of the first support plate 110 facing the second support plate 120; the second slide rail 230 is perpendicular to the rotation axis of the second support plate 120, and the extension direction of the second slide rail 230 is parallel to the first support plate 110; the second slider 220 is slidably disposed on the second slide rail 230; one end of the connecting rod 210 is fixedly connected to the second slider 220, and the other end of the connecting rod 210 is hinged to the first slider 190, and the connecting rod 210 is perpendicular to the first support plate 110; the driving component is used to drive the second slider 220 to slide on the second slide rail 230.

[0035] The support and measuring device for open osteotomy proposed in this invention can accurately ensure the distance and angle of the gap at the osteotomy site, thereby ensuring the accuracy of the final plate fixation. In specific use, the device is directly embedded in the gap at the osteotomy site. Then, the driving component drives the second slider 220 to slide on the second slide rail 230, which in turn drives the first slider 190 to move on the first slide rail 180. This increases the angle between the second support plate 120 and the first support plate 110, so that the first support plate 110 and the second support plate 120 respectively abut against the bone walls on both sides of the gap, preventing the bones on both sides of the osteotomy site from getting close to each other. This ensures that the size and angle of the gap at the osteotomy site remain stable, thereby improving the accuracy of the final plate fixation. After the plate is fixed, the driving component drives the second slider 220 to slide in the opposite direction, which in turn drives the first slider 190 to slide, thereby reducing the angle between the second support plate 120 and the first support plate 110. Then, the device can be removed from the gap at the osteotomy site without affecting the patient's normal life.

[0036] In addition, as attached Figure 1 - Appendix Figure 4 The driving component includes a lead screw 260, a first base 240, and a second base 250. Both the first base 240 and the second base 250 are located on the side of the first support plate 110 facing the second support plate 120. The line connecting the first base 240 and the second base 250 is parallel to the extending direction of the second slide rail 230. One end of the lead screw 260 is rotatably connected to the first base 240, and the other end is rotatably connected to the second base 250. The length of the lead screw 260 is greater than the length of the second slide rail 230. The lead screw 260 is parallel to the second slide rail 230. The second slider 220 has an internal threaded hole that mates with the lead screw 260. The second slider 220 is screwed onto the lead screw 260. This technical solution improves the structure of the driving component, allowing the second slider 220 to slide along the second slide rail 230 by rotating the lead screw 260.

[0037] Meanwhile, the drive component also includes a micro motor 330, a battery 370, a control unit (not shown), and a remote controller (not shown); the remote controller and the control unit are wirelessly connected; the control unit, the battery 370, and the micro motor 330 are all mounted on the first support plate 110; the micro motor 330 is used to drive the lead screw 260 to rotate; the control unit is used to control the start, stop, and rotation direction of the micro motor 330; the battery 370 is used to supply power to the micro motor 330 and the control unit.

[0038] By setting up a remote control, surgeons can directly control the angle of the second support plate 120 relative to the first support plate 110, making it more convenient to use.

[0039] In addition, the drive component also includes a rotating rod 270, a worm gear 280, a worm 290, a first gear 310, and a second gear 320; the rotating rod 270 is rotatably mounted on the first support plate 110; the rotating rod 270 is located between the lead screw 260 and the second support plate 120; the rotating rod 270 is perpendicular to the lead screw 260; the worm gear 280 is coaxially connected to the lead screw 260; the worm 290 is coaxially connected to the rotating rod 270; the worm 290 meshes with the worm gear 280; the first gear 310 is coaxially connected to the rotating rod 270; the second gear 320 is coaxially connected to the output shaft of the micro motor 330; the first gear 310 and the second gear 320 mesh. Here, both the first gear 310 and the second gear 320 are helical gears.

[0040] By setting the connection method of worm gear 280 and worm 290, speed reduction and torque increase and self-locking can be achieved, thereby ensuring the angular stability of the second support plate 120 relative to the first support plate 110, so as to better support the gap at the osteotomy site.

[0041] Meanwhile, the drive component also includes a first baffle 340 and a second baffle 350; both the first baffle 340 and the second baffle 350 are vertically connected to the first support plate 110; one end of the rotating rod 270 is rotatably connected to the first baffle 340; the other end of the rotating rod 270 is rotatably connected to the second baffle 350; the first support plate 110 includes a first side 140, and a second side 160 and a third side 170 arranged opposite to each other; the first baffle 340 is close to the second side 160; the second baffle 350 is close to the third side 170; the second support plate 120 is hinged to the first side 140. By setting the first baffle 340 and the second baffle 350, the structure and function of the drive component are further improved.

[0042] Furthermore, the first baffle 340 and the second baffle 350 have the same structure and dimensions; the side edge of the first baffle 340 away from the first support plate 110 is inclined relative to the first support plate 110, and the side edge of the first baffle 340 away from the first support plate 110 can fit and abut against the side of the second support plate 120 facing the first support plate 110; the side edge of the second baffle 350 away from the first support plate 110 is inclined relative to the first support plate 110, and the side edge of the second baffle 350 away from the first support plate 110 can fit and abut against the side of the second support plate 120 facing the first support plate 110.

[0043] Through the above technical solution, the first baffle 340 and the second baffle 350 can support the second support plate 120. That is, when the second support plate 120 rotates to its smallest angle relative to the first support plate 110, the first baffle 340 and the second baffle 350 simultaneously abut against the second support plate 120 (as shown in the attached figure). Figure 2 ).

[0044] Meanwhile, a grasping ring 360 is connected to the side of the first baffle 340 opposite to the second baffle 350; it also includes a third support plate 130; the third support plate 130 is connected to the first support plate 110 near the first side 140, and the third support plate 130 is perpendicular to the first support plate 110; the second support plate 120 is hinged to the side of the third support plate 130 away from the first support plate 110. By providing the grasping ring 360, it is easier to remove this device from the gap at the osteotomy site.

[0045] In addition, the support and measuring device for open osteotomy also includes a third baffle 380, an electric push rod 390, and an abutment plate 410; the third baffle 380 is vertically connected to the first support plate 110; the first support plate 110 also includes a fourth side 150 opposite to the first side 140; the third baffle 380 is close to the fourth side 150; the base of the electric push rod 390 is connected to the side of the first support plate 110 facing the second support plate 120, and the electric push rod 390 is close to the third baffle 380; the extension and retraction direction of the electric push rod 390 is perpendicular to the first support plate 110; the extension and retraction end of the electric push rod 390 is connected to the abutment plate 410, and the abutment plate 410 is parallel to the first support plate 110; the control unit is also used to control the extension and retraction of the electric push rod 390.

[0046] Through the above technical solution, the electric push rod 390 drives the abutment plate 410 to move, so that the abutment plate 410 and the side of the second support plate 120 away from the hinge point keep the position synchronized, that is, the distance between the abutment plate 410 and the first support plate 110 and the distance between the side of the second support plate 120 away from the hinge point and the first support plate 110 are the same, so that the abutment plate 410 can fit against the bone wall on one side of the osteotomy site, and the support effect is better.

[0047] Meanwhile, the support and measuring device for open osteotomy also includes an elastic membrane 420; one side of the elastic membrane 420 is connected to the abutment plate 410; the other side of the elastic membrane 420 is connected to the side of the second support plate 120 away from the first side 140; the abutment plate 410 is located on the side of the third baffle 380 away from the first support plate 110; a first elastic buffer layer (not shown) is provided on the side of the abutment plate 410 away from the first support plate 110.

[0048] The connecting rod 210 is perpendicular to the first support plate 110; a second elastic buffer layer (not shown) is provided on the side of the first support plate 110 opposite to the second support plate 120; a third elastic buffer layer (not shown) is provided on the side of the second support plate 120 opposite to the first support plate 110; and a fourth elastic buffer layer (not shown) is provided on the side of the third support plate 130 opposite to the third baffle 380. By providing the elastic membrane 420, the first elastic buffer layer, the second elastic buffer layer, the third elastic buffer layer, and the fourth elastic buffer layer, the device can provide gentler support to one side of the bone wall at the osteotomy site, preventing damage to the bone.

[0049] In addition, the support and measuring device for this open osteotomy also includes an angle sensor (not shown); the angle sensor is communicatively connected to the control unit; the angle sensor is located near the first side 140 of the first support plate 110; the angle sensor is used to detect the angle of the second support plate 120 relative to the first support plate 110 in real time. By setting the angle sensor, the control unit can obtain the angle of the second support plate 120 relative to the first support plate 110 in real time, and then, based on the length of the second support plate 120, can know the distance between the side of the second support plate 120 away from the hinge and the first support plate 110 in real time; the abutment plate 410 is also provided with a distance sensor (not shown) communicatively connected to the control unit; the control unit obtains the distance between the abutment plate 410 and the first support plate 110 in real time through the distance sensor, and then controls the extension and retraction of the electric push rod 390 to ensure that the abutment plate 410 and the side of the second support plate 120 away from the hinge remain in synchronized position. The first support plate 110, the second support plate 120 and the abutment plate 410 are all made of titanium alloy, which ensures structural strength while also providing better biocompatibility with human tissue.
