Description

Technical Field

[0001] The present invention relates to the technical field of medical surgery, and specifically relates to an adjustable osteotomy guide plate for knee joint surgery. Background Art

[0002] Total knee arthroplasty and unicompartmental knee arthroplasty are the core means for treating advanced osteoarthritis. Traditional surgeries rely on the experience of surgeons to perform osteotomy manually, with a relatively high error rate, which easily leads to poor prosthesis position and joint force line deviation, causing problems such as postoperative pain and joint instability. Especially when only part of the joint is replaced and healthy bone tissue needs to be retained, the requirement for osteotomy accuracy is even higher.

[0003] However, when installing the structural guide plate for the knee joint, it is necessary to fix the osteotomy guide plate at the position of the patella through bone nails or screws, thus requiring drilling of the knee joint. At this time, if there is still a certain error after the installation of the osteotomy guide plate, since the knee joint of the patient cannot be drilled again to adjust the position, only osteotomy can be performed according to the current position, and the angle of the osteotomy guide plate cannot be finely adjusted, thus affecting the success rate of the surgery.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 11The present invention provides a technical solution: an adjustable osteotomy guide for knee joint surgery, comprising a support seat 1, a guide plate 18 is provided at the upper end of the support seat 1, a rotating disk 2 is rotatably connected to the interior of the support seat 1, a guide rod 3 is fixedly connected to the inner wall of the rotating disk 2, a positioning disk 4 is symmetrically sleeved on both ends of the guide rod 3, a connecting plate 13 is symmetrically fixed to the outer wall of the positioning disk 4, and the connecting plate 13 is horizontally arranged inside the support seat 1, a rotating ring 5 is rotatably connected to the cavity of the positioning disk 4, two inclined sliders 6 are symmetrically fixed to the outer wall of the rotating ring 5, and a drainage structure is installed in the cavity between the positioning disk 4 and the rotating ring 5, which can discharge liquid into the interior of the connecting plate 13;

[0033] A rotating shaft 14 is mounted on the upper surface of one end of each connecting plate 13 away from the positioning plate 4. A pushing structure is provided on the upper end of the rotating shaft 14. The pushing structure can push the guide plate 18 to move through the liquid input by the drainage structure.

[0034] A connecting ring 28 is fixedly connected to one end of the rotating ring 5 away from the rotating disk 2. A transmission wheel 29 is sleeved on the outer wall of the connecting ring 28. An adjustment structure is sleeved on the other end of the transmission wheel 29. The adjustment structure can cooperate with the infusion structure to change the pushing distance of the pushing structure on the same side.

[0035] Specifically, a horizontal osteotomy knife groove is formed through one side of the guide plate 18, and the doctor can insert the osteotomy knife into the guide plate 18 to cut the patient's knee bone.

[0036] Among them, the drainage structure includes two groups of inclined sliders 6, which are symmetrically arranged in the cavity of the positioning plate 4 along the outer wall of the rotating ring 5, and each group of inclined sliders 6 are symmetrically slidably connected to the inner wall of the positioning plate 4. Each inclined slider 6 is fixed with a spring 7 on the side close to the inner wall of the positioning plate 4, and each inclined slider 6 can interfere with the inclined top block 8.

[0037] Among them, two drainage holes 12 are symmetrically provided on the inner side wall of the positioning plate 4, and each drainage hole 12 is connected to the connecting plate 13 at the corresponding position. Two liquid outlet holes 11 are also symmetrically provided inside the rotating ring 5, and each liquid outlet hole 11 is connected to the guide rod 3, and the drainage holes 12 and the liquid outlet holes 11 are respectively arranged on both sides of the inclined slider 6 at the corresponding position. A cover plate 9 is fixedly connected to the side of each inclined slider 6 close to the liquid outlet hole 11, and the cover plate 9 can interfere with the upper groove of the liquid outlet hole 11, and a slot 10 is fixedly connected to the side of the inclined top block 8 close to the cover plate 9, and the slot 10 can be plugged into the cover plate 9.

[0038] Specifically, refer to Figure 7 and Figure 9When the rotating ring 5 rotates counterclockwise, the distance between each set of inclined sliders 6 and the inclined top block 8 will continue to shrink, so that the liquid between each set of inclined sliders 6 and the inclined top block 8 is pushed into the interior of the connecting plate 13 through the drainage hole 12. At the same time, the two inclined sliders 6 collide with each other to prevent insufficient pressure between the inclined sliders 6 and the inclined top block 8. Then, when one of the inclined top blocks 8 passes over the drainage hole 12, it will come into contact with the inclined slider 6. Figure 7 , the oblique edge of the inclined ejector block 8 will conflict with the oblique edge of the inclined slider 6, so that the inclined ejector block 8 pushes the inclined slider 6 to slide toward the inner wall of the positioning plate 4. At the same time, during the sliding process of the inclined slider 6, the cover plate 9 will block the notch of the liquid outlet 11 to prevent the liquid from flowing back into the interior of the guide rod 3;

[0039] Then, when the rotating ring 5 rotates clockwise, the cover plate 9 will be inserted into the cavity of the slot 10, and the liquid outlet 11 will be connected to the drain hole 12. At this time, the liquid inside the connecting plate 13 and the positioning disk 4 will flow back to the inside of the guide rod 3.

[0040] Among them, the pushing structure includes a movable rod 15, which is fixed to the upper end of the rotating shaft 14, and the side surface of the movable rod 15 is fixed with a hose 16 connected to the connecting plate 13, and the upper end of the movable rod 15 is fixed with a universal shaft 19, and the upper end of the universal shaft 19 is movably connected to a connecting block 20, and the upper end of the connecting block 20 is connected to the guide plate 18. Each movable rod 15 is in contact with an elastic positioning component 17 on the side away from the positioning plate 4, and the elastic positioning component 17 is slidably connected inside the support seat 1.

[0041] The lower end of the circular arc rack 27 is meshed with a gear ring 26, and the inner side wall of the gear ring 26 is fixed to the liquid storage cylinder 21. The upper surface of the liquid storage cylinder 21 is provided with two sliding grooves 22, and a sliding piece 23 is slidably connected inside each sliding groove 22. The sliding piece 23 is penetrated and installed with an infusion tube 24 above and below, and the infusion tube 24 is connected to the guide rod 3. The lower surface of the rotating disk 2 is slidably connected with two arc-shaped sliding pieces 25 corresponding to the positions of the sliding grooves 22, and the arc-shaped sliding pieces 25 are fixed to the infusion tube 24 at the corresponding positions. When the liquid storage cylinder 21 and the gear ring 26 rotate and drive the circular arc rack 27 to be selected, the sliding piece 23 will also slide synchronously inside the sliding groove 22, and the arc-shaped sliding piece 25 will also slide on the lower surface of the rotating disk 2, so that the infusion tube 24 is always in a vertical state and maintain the communication relationship between the liquid storage cylinder 21, the infusion tube 24 and the guide rod 3.

[0042] Specifically, the support base 1 is provided with a fine-tuning cavity 47 which is larger than the range of motion of the connecting plate 13 and the movable rod 15. The connecting plate 13 can rotate slightly around the positioning plate 4. At the same time, as the rotation angle of the connecting plate 13 increases, the distance between the movable rods 15 on the two connecting plates 13 on the same side decreases.Figure 10 An elastic member is installed at one end of the elastic positioning component 17 away from the movable rod 15. At this time, the elastic positioning component 17 will simultaneously resist the outer wall of the movable rod 15, so that the movable rod 15 is always in a vertical state, thereby allowing the guide plate 18 to tilt slightly to the left and right.

[0043] Among them, the adjustment structure includes an active rod 33, which is rotatably connected to the cavity of the support seat 1, and a sliding bar 35 is rotatably connected to the outer wall of the active rod 33. The end of the sliding bar 35 away from the active rod 33 is rotatably connected to the liquid storage cylinder 21. Pentagonal prisms 34 are symmetrically fixed on both sides of the active rod 33, and each pentagonal prism 34 is connected to the end away from the active rod 33 with a driven rod 32. The outer wall of the driven rod 32 is provided with a transmission wheel 2 30, and the transmission wheel 2 30 and the transmission wheel 1 29 are jointly provided with a toothed belt 31.

[0044] Among them, the outer wall of the active rod 33 is sleeved with a gear ring 2 36, and a gear ring 37 is engaged on one side of the gear ring 2 36. The inner wall of the gear ring 37 is fixed with a connecting rod 38, and one end of the connecting rod 38 is slidably connected to a sliding cylinder 39. The end of the liquid storage cylinder 21 close to the sliding cylinder 39 is fixed to a locking rod 42. One end of the sliding cylinder 39 and the locking rod 42 are both fixed with a debugging disk 43. The outer wall of the sliding cylinder 39 is provided with an inclined groove 40, and the outer wall of the inclined groove 40 is in contact with a card rod 41, and the card rod 41 can be inserted into the locking rod 4 2, a plurality of locking grooves are provided on the outer wall of the locking rod 42. At the same time, when the debugging disk 43 is pushed or pulled, the locking rod 42, the liquid storage cylinder 21, the gear ring 1 26 and the sliding bar 35 will also move synchronously. During the movement of the sliding bar 35, the active rod 33 will be driven to slide together, so that the pentagonal prism 34 is separated from one of the driven rods 32 on both sides. At this time, the rotation of the active rod 33 will no longer drive the separated driven rod 32, so that the active rod 15 on the same side will not be driven to lift by the drainage structure, so that the active rod 15 on the same side will not be driven to lift by the drainage structure. Figure 1 As a reference, the guide plate 18 can be tilted forward and backward, and at the same time, Figure 4 The connecting block 20 is divided into a sliding block 1 201 and a sliding block 202, wherein the sliding block 202 is fixedly connected to the guide plate 18, and the sliding block 101 is slidably connected to the guide plate 18. At the same time, the sliding block 101 and the sliding block 202 are slidably connected, so that when the guide plate 18 tilts forward and backward, the movable rods 15 on the front and rear sides can normally move slightly closer to each other;

[0045] refer to Figure 8 and Figure 11 The cavity of the guide rod 3 is divided into two areas, which are connected to the positioning disk 4 at the corresponding position respectively. When the liquid storage cylinder 21 slides, the sliding piece 23 will also slide synchronously inside the sliding groove 22, so that the infusion tube 24 is always connected to the guide rod 3.

[0046] Two laser emitters 44 are installed at one end of the guide plate 18 away from the debugging disk 43. Four fixing grooves 45 are opened through the outer wall of the support base 1, and bone nails or screws can be installed through the fixing grooves 45 to fix the support base 1.

[0047] Specifically, refer to Figure 1 and Figure 3 When the sliding cylinder 39 is pushed toward the support base 1, the inclined groove 40 will resist and push the locking rod 41 toward the debugging disk 43. At this time, if the debugging disk 43 is also pushed toward the support base 1 in advance, the locking rod 41 will be inserted into the locking groove on the outer surface of the locking rod 42, thereby locking the locking rod 42 to prevent the guide plate 18 from shaking during use.

[0048] Working principle: When the height and angle of the guide plate 18 need to be adjusted, the medical staff only needs to turn the two debugging disks 43 respectively. When the larger debugging disk 43 is turned, the gear ring 26 is driven to rotate. The gear ring 26 drives the rotating disk 2 to rotate slightly by engaging with the arc rack 27, so that the pushing structure connected to the rotating disk 2 drives the guide plate 18 to tilt left and right. Then, if the height of the guide plate 18 needs to be adjusted, the medical staff can turn the smaller debugging disk 43 to drive the driven rod 32 to rotate. The driven rod 32 then drives the drainage structure through the toothed belt 31. structure, so that the drainage structure can extract the liquid inside the liquid storage cylinder 21 and then use the extracted liquid to lift the pushing structure upward. Then, when it is necessary to tilt the guide plate 18 in the front-to-back direction, by pushing or pulling the larger debugging disk 43, the drainage structure at the corresponding position cannot extract the liquid, so that the pushing structure on the other side can be used normally, so that the guide plate 18 can be tilted back and forth. When the patient undergoes knee joint surgery, on the premise that the support seat 1 has been installed on the bone wall, the guide plate 18 can be adjusted later to improve the success rate of the operation.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
