[0002] Fracture fixation with steel plates is a common surgical treatment for fractures, which is particularly suitable for long bone fractures with obvious damage and displacement. Strong steel plate internal fixation is beneficial to the protection of muscle and soft tissue blood supply at the fracture end, reducing movement and friction at the fracture site, thereby alleviating pain and swelling and promoting early healing of the fracture end. At the same time, the screws on the steel plate can also pass through the bones to firmly fix the fracture site together to prevent displacement and dislocation. In addition, the screws can also stimulate bone cell growth and differentiation, further promoting fracture healing.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1 Reference Figure 1-Figure 8 , an adjustable orthopedic implant fixation device, which is used in the field of medical devices, comprises: a fixing frame 2 arranged on an operating table 1, and a sliding block 3 is provided on the top of the fixing frame 2 through a precisely machined guide rail. The sliding block 3 is tightly matched with the guide rail and slides smoothly, ensuring that the sliding block 3 can slide accurately and stably on the top of the fixing frame 2 along the guide rail.

[0020] The top of the sliding block 3 is connected to the rotating seat 8 through a damping rotation mechanism, and the rotating seat 8 can rotate smoothly relative to the sliding block 3 within a certain range to meet the needs of adjusting the angle of the steel plate during surgery. At the same time, in the absence of external force, the rotating seat 8 can maintain a stable fixed position and will not rotate, thereby ensuring the accuracy and safety of the surgery. The damping rotation mechanism uses a common damping shaft.

[0021] The top of the rotating seat 8 is fixedly connected to the support frame 4, and the structure of the support frame 4 is reasonably designed and stable, and is used to support and fix subsequent components. An extension rod 6 is adjustably arranged in the support frame 4, and the extension rod 6 can slide smoothly in the support frame 4 to adapt to different surgical positions and patient needs.

[0022] On the extension rod 6, a lifting rod 11 is further adjustable, and the lifting rod 11 can slide up and down accurately in the extension rod 6 to meet the needs of adjusting the height of the steel plate during surgery. The bottom end of the lifting rod 11 is designed as a spherical structure and embedded in the fixed block 13. At the same time, the outer wall of the spherical structure is provided with a rubber pad to increase the friction between the lifting rod 11 and the fixed block 13 so that it will not swing or rotate at will. This design enables the lifting rod 11 and the fixed block 13 to achieve relative rotation by manual pulling, so as to conveniently adjust the inclination angle of the steel plate to adapt to different fixed angles and positions. A bidirectional screw 15 is provided through and rotated on one side of the fixed block 13. The outer wall of the bidirectional screw 15 is provided with two first clamping plates 7 for clamping the steel plate. By rotating the bidirectional screw 15, the two first clamping plates 7 can be driven to approach each other so that the steel plate can be clamped without manual placement, thereby improving the stability of placement and pressing.

[0023] A first limiting assembly is provided in the fixing block 13, which is composed of a plurality of precise mechanical parts and is used to firmly fix the lifting rod 11 and the fixing block 13 to prevent them from relative movement when rotation is not required. At the same time, a second limiting assembly is also provided in the support frame 4, which is also composed of a plurality of precise mechanical parts and is used to firmly fix the lifting rod 11 in the extension rod 6 and the extension rod 6 in the support frame 4, thereby ensuring that the height and position of the entire device can be stably and accurately adjusted.

[0024] In addition, the device further includes a pressing rod 18, which is slidably disposed in the lifting rod 11 and is used in conjunction with the first limit assembly and the second limit assembly. When the position of the lifting rod 11, the extension rod 6 or the fixing block 13 needs to be adjusted, the doctor can simply press the pressing rod 18 to release the fixation of them, thereby achieving flexible and rapid adjustment.

[0025] The specific structure of the first limit assembly includes a plurality of second mounting holes 35 provided at the bottom end of the lifting rod 11, and a first pin 36 slidably disposed in the second mounting hole 35. A third spring 37 is sleeved on the outer wall of the first pin 36, and the two ends of the third spring 37 are respectively fixedly connected to the inner wall of one side of the second mounting hole 35 and the outer wall of the first pin 36. At the same time, a plurality of second pins 39 used in cooperation with the second mounting holes 35 are slidably disposed in the fixed block 13, and a fourth spring 40 is sleeved on the outer wall of the second pin 39, and the two ends of the fourth spring 40 are respectively fixedly connected to the inner wall of one side of the fixed block 13 and the outer wall of the second pin 39. When the relative position of the lifting rod 11 and the fixed block 13 is determined, one of the second pins 39 will extend into the corresponding second mounting hole 35 and closely cooperate with the first pin 36, thereby realizing the firm fixation of the lifting rod 11 and the fixed block 13. At this time, the lifting rod 11 and the fixed block 13 will not rotate or swing relative to each other, thereby improving the stability during the operation and avoiding movement during the fixation process.

[0026] In order to release the fixing block 13, a sliding rod 20 is also slidably provided in the lifting rod 11, and the top of the sliding rod 20 is fixedly connected to the bottom of the pressing rod 18. A mounting cavity 34 is provided at the bottom end of the lifting rod 11, and a conical block 38 used in conjunction with a plurality of first pins 36 is slidably provided in the mounting cavity 34. The top of the conical block 38 is fixedly connected to the sliding rod 20. When the doctor presses the pressing rod 18, the sliding rod 20 moves downward and pushes the conical block 38 to move, thereby pushing the first pin 36 to move outward, so that the second pin 39 is disengaged from the second mounting hole 35, thereby releasing the fixing of the lifting rod 11 and the fixing block 13. At the same time, a second spring 33 is provided on the outer wall of the sliding rod 20, and the two ends of the second spring 33 are respectively fixedly connected to one side of the lifting rod 11 and the bottom of the pressing rod 18, so as to enable the pressing rod 18 and the sliding rod 20 to automatically reset after the fixing is released, so that there is no need to manually pull upward to reset, thereby improving the convenience during use.

[0027] The specific structure of the second limiting assembly is also complex and precise, including a wedge block 21 slidably arranged in the extension rod 6 and an insertion rod 19 slidably arranged in the extension rod 6. One end of the insertion rod 19 is fixedly connected to the wedge block 21, and two fixed rods 23 are fixedly arranged in the extension rod 6. The outer walls of the two fixed rods 23 are slidably sleeved with two sliding plates 26 used in conjunction with the wedge block 21. The outer wall of the fixed rod 23 is also fixedly sleeved with a limiting ring 24 located between the two sliding plates 26 and a first spring 25 sleeved on the outer wall of the fixed rod 23. The two ends of the first spring 25 are respectively fixedly connected to the side of the limiting ring 24 and the sliding plate 26 that are close to each other. When the wedge block 21 moves, it will push the sliding plate 26 to move and compress or stretch the first spring 25, thereby realizing the extension or retraction of the insertion rod 19 and the insertion block 27. A plurality of insertion holes 28 are provided at the top and bottom of the extension rod 6. The insertion holes 28 are slidably sleeved with insertion blocks 27 that are in conflict with the inner wall of the support frame 4, and the other end of the insertion block 27 is fixedly connected to the corresponding sliding plate 26. At the same time, the outer wall of the plug rod 19 is sleeved with a tension spring 41, and the two ends of the tension spring 41 are respectively fixedly connected to the inner wall of one side of the extension rod 6 and the outer wall of the plug rod 19, so as to enable the plug rod 19 and the plug block 27 to automatically reset after the adjustment is completed. At the same time, in order to increase the friction between the plug block 27 and the support frame 4, the top of the plug block 27 and the inner wall of one side of the support frame 4 are provided with anti-slip grooves. In addition, one side of the wedge block 21 and the plug rod 19 is provided with a clearance groove 22 corresponding to the fixed rod 23, so as to facilitate the smooth movement of the wedge block 21 and the plug rod 19, and effectively avoid the plug rod 19 and the fixed rod 23 from being stuck.

[0028] In order to fix the lifting rod 11 in the extension rod 6, a sleeve rod 17 is fixedly provided on the top of the extension rod 6, and the lifting rod 11 is slidably provided in the sleeve rod 17. The outer walls of the lifting rod 11 and the sleeve rod 17 are provided with a plurality of first positioning holes 29 used in conjunction with the insertion rod 19. When the insertion rod 19 is inserted into the corresponding first positioning hole 29, the lifting rod 11 can be firmly fixed, and the lifting rod 11 will not move up and down at this time. At the same time, the outer wall of the pressing rod 18 is also provided with a plurality of adjustment grooves 30 corresponding to the first positioning holes 29, and a ball 31 is provided in the adjustment groove 30. Since the adjustment groove 30 is designed to be small at the top and large at the bottom, when the doctor presses the pressing rod 18, the ball 31 will contact and push the insertion rod 19 to move and compress the tension spring 41, so that the insertion rod 19 is disengaged from the first positioning hole 29, so that one end of the insertion rod 19 is flush with the outer wall of the lifting rod 11, thereby releasing the fixation of the lifting rod 11, and the lifting rod 11 can move up and down at this time. At the same time, a positioning block 32 corresponding to the adjustment slot 30 is fixedly provided on the inner wall of the lifting rod 11 to limit the ball 31 and prevent it from moving when not needed, and to prevent the ball 31 from escaping from the adjustment slot 30 .

[0029] Example 2 On the basis of Example 1, the present invention has made further improvements in details. A guide rod 14 is fixedly provided through one side of the fixing block 13, and the first splint 7 is slidably sleeved on the guide rod 14. The provision of the guide rod 14 not only enhances the stability of the first splint 7 during movement, but also makes the clamping process smoother and more precise. At the same time, grooves 16 are provided at the bottom ends of the two first splints 7 on the sides close to each other. The design of these grooves 16 enables the steel plate to be stably placed between the two first splints 7 and increases the stability of the clamping. In addition, when the steel plate is clamped, the bottom of the first splint 7 will not directly contact the bone, thereby avoiding possible damage.

[0030] Two placement trays 5 are also fixedly provided on both sides of the support frame 4. The design of these placement trays 5 facilitates doctors to quickly and accurately take the required implantation tools during the operation, thereby improving the efficiency and safety of the operation.

[0031] In order to clamp the fixing frame 2 on the operating table 1 more stably, the present invention further provides two second clamping plates 10 on one side of the fixing frame 2 through a guide rail. Two bolts 12 are provided through the bottom of the fixing frame 2, and the tops of the bolts 12 are rotatably connected to the corresponding second clamping plates 10. When the doctor needs to fix the fixing frame 2, he only needs to simply turn the bolts 12 to make the second clamping plates 10 approach the operating table 1 and make close contact, thereby achieving a firm clamping of the operating table.

[0032] Finally, in order to realize the flexible movement of the sliding block 3 on the fixing frame 2, the present invention has a first screw rod 9 that is rotatably provided in the fixing frame 2, and the sliding block 3 is threadedly sleeved on the first screw rod 9. When the doctor needs to adjust the position of the sliding block 3, he only needs to rotate the first screw rod 9 to make the sliding block 3 move accurately and stably along the axial direction of the first screw rod 9, thereby realizing the flexible adjustment of the position of the steel plate. This design not only improves the accuracy and safety of the operation, but also makes the use of the entire device more convenient and efficient.

[0033] In the present application, first, the patient is moved onto the operating table 1, and a skin incision is performed. The fixing frame 2 is clamped onto the operating table 1, and then the bolt 12 is screwed upward to drive the second clamping plate 10 to move upward, and the fixing frame 2 is clamped onto the operating table 1 with the fixing frame 2, and then the supporting frame 4 is rotated to move the first clamping plate 7 above the bone; Then, the steel plate is placed between the two first clamping plates 7, and the bidirectional screw 15 is rotated. The rotation of the bidirectional screw 15 can drive the two first clamping plates 7 to approach each other, and the steel plate can be clamped in the two grooves 16; Secondly, hold the sleeve rod 17 and use the thumb to press the pressing rod 18. The downward movement of the pressing rod 18 can drive the position of the adjusting slot 30 to move downward. The downward movement of the adjusting slot 30 can drive the ball 31 to approach the insertion rod 19 and push the insertion rod 19 to move outward until the insertion rod 19 is separated from the first positioning hole 29. At this time, the lifting rod 11 can move up and down on the sleeve rod 17, and the movement of the insertion rod 19 can drive the wedge block 21 to move. When the wedge block 21 is away from the two sliding plates 26, the two sliding plates 26 can be in the first spring 25. Under the action of force, they approach each other and drive the insert block 27 away from the support frame 4. At this time, the extension rod 6 can move in the support frame 4, and the pressing rod 18 can also drive the sliding rod 20 to move downward during the downward movement. The downward movement of the sliding rod 20 can drive the conical block 38 to move downward. The downward movement of the conical block 38 can push the first pin 36 to move, and the first pin 36 can push out the second pin 39 located in the second mounting hole 35 during the movement. At this time, the fixing block 13 can be rotated and adjusted on the lifting rod 11 until the steel plate contacts the bone; Then release the pressing rod 18, at this time, the pressing rod 18 can be reset and moved upward under the action of the second spring 33, and the first pin 36 can be reset and moved under the action of the third spring 37 during the upward reset of the pressing rod 18, and the second pin 39 can be reset and moved under the action of the fourth spring 40, and inserted into the corresponding second mounting hole 35, at this time, the fixing block 13 is in a fixed state, and the upward movement of the pressing rod 18 can drive the adjusting slot 30 to move upward, and the insertion rod 19 can be reset and moved under the action of the tension spring 41, and drive the wedge block 21 to move, the movement of the wedge block 21 can drive the two sliding plates 26 to move away from each other, and drive the insertion block 27 to contact the support frame 4, so as to fix the support frame 4 and the extension rod 6, and the insertion rod 19 can be inserted into the corresponding first positioning hole 29 during the movement to fix the lifting rod 11; Finally, proceed with the subsequent drilling and nailing steps.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
