Description

Technical Field

[0001] This invention relates to the field of orthopedic surgery technology, specifically to a bone plate clamping device suitable for orthopedic surgery. Background Technology

[0002] In orthopedic surgery, a bone plate is an internal fixation device primarily used for fracture treatment. It is typically a metal plate made of biocompatible materials such as medical-grade stainless steel, titanium alloy, or cobalt-chromium alloy, with a series of holes for internal fixation of fractures. When a bone is fractured, the surgeon surgically reduces the fractured bone fragments, then applies this bone plate to the bone surface, and finally screws bone screws through the holes in the plate into the bone to firmly fix the bone plate to the fracture site. Clamping devices are needed during the process of applying the bone plate to the bone surface. In current technology, the components of the clamping devices are not easy to disassemble, making postoperative cleaning difficult and prone to bacterial residue.

[0003] Patent CN217162255U discloses a bone plate clamping device suitable for orthopedic surgery. This patent includes a screw, a screw knob, a guide head, a connecting rod, and a handle. One end of the connecting rod is connected to the handle, and the other end is connected to the guide head. The connecting rod has multiple corner sections. The handle and guide head are aligned. The guide head has a guide hole and a mounting groove. The mounting groove forms a space for fitting the clamped bone plate. The guide hole penetrates the bottom surface of the mounting groove, allowing for a surgical incision to be made near the proximal end of the distal radius fracture site. This facilitates the clamping of the distal radius palmar locking bone plate, enabling medical personnel to more easily and conveniently perform the fixation operation of the distal radius palmar locking bone plate.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-10One embodiment of the present invention is a bone plate clamping device suitable for orthopedic surgery, comprising a connector 1, a clamping rod 2 hinged to the front side of the connector 1, a clamping plate 3 fixedly connected to the front end of the clamping rod 2, a flexible pad 4 fixedly connected to the side of the clamping plates 3 that are close to each other, the flexible pad 4 being used to clamp and conform to the bone plate, a fixing device 5 disposed on the rear side of the connector 1, the fixing device 5 being used to fix the clamping components, making the placement of the bone plate more stable, a flushing device 6 disposed on the rear side of the connector 1, the flushing device 6 being used to clean and disinfect the wound after surgery, the clamping rod 2 driving the clamping plate 3 and the flexible pad 4 to rotate and reset, thereby clamping the bone plate, facilitating the placement of the bone plate, a nut 8 being rotated and fixed to the extension rod 9 through threads on its surface, thereby facilitating the doctor's grasping and improving convenience, after the connector 1 and the clamping rod 2 are removed from the extension rod 9 by the nut 8, it is convenient for cleaning and maintenance, the connector 1 includes a toggle member 7, the toggle member 7 being fixedly connected to the rear end of the clamping rod 2, the nut Nut 8 is fixedly connected to the rear side of connector 1. The outer surface of nut 8 is threaded with extension rod 9. Extension rod 9 is used to extend the operating distance of clamping component. Connector 1 also includes handle 10. Handle 10 is set on the rear side of extension rod 9. Rotating shaft 11 is rotatably connected to the inner surface of handle 10. Sleeve shaft 12 is fixedly connected to the front end of rotating shaft 11. An annular inclined groove 13 is opened on the front side of sleeve shaft 12. Inner sleeve 14 is fixedly connected to the rear side of inner surface of extension rod 9. Torsion spring is provided at the hinge of clamping rod 2 and connector 1. The rear side of sleeve shaft 12 abuts against the front side of handle 10. The rear end of extension rod 9 is engaged with the inner surface of sleeve shaft 12. Pressing the actuating component 7 towards the side closer to extension rod 9 makes it easier to open clamping rod 2, further improving the convenience of the device. Extension rod 9 rotates in handle 10 through sleeve shaft 12 and rotating shaft 11, thereby driving connector 1 and clamping rod 2 to rotate, thereby quickly adjusting bone plate angle and improving device applicability.

[0024] Working principle: Rotating the clamping rod 2 opens the clamping rod, which in turn opens the clamping plate 3 and the flexible pad 4, allowing the flexible pad 4 to fit against both sides of the bone plate. Then, the clamping rod 2 is released. At this time, the torsion spring at the hinge of the clamping rod 2 and the connecting piece 1 elastically drives the clamping rod 2 to rotate back to its original position. The clamping rod 2 then drives the clamping plate 3 and the flexible pad 4 to rotate back to their original position, thereby clamping the bone plate for easy placement. The nut 8 is inserted into the front end of the extension rod 9, and then the connecting piece 1 is rotated. The connecting piece 1 drives the nut 8 to rotate, and the nut 8 is rotated and fixed to the extension rod 9 through the threads on its surface, making it easier for the doctor to grasp and improving convenience. Conversely, the connecting piece... After the clamping rod 1 and clamping rod 2 are removed from the extension rod 9 via the nut 8, they are easy to clean and maintain. When clamping rod 2 needs to be opened, hold the actuating parts 7 on both sides and press the actuating parts 7 towards the side closer to the extension rod 9. This makes it easier to open clamping rod 2 and further improves the convenience of the device. Insert the rear end of the extension rod 9 into the sleeve shaft 12. At this time, hold the handle 10 with one hand and the extension rod 9 with the other hand, and rotate the extension rod 9. The extension rod 9 rotates in the handle 10 through the sleeve shaft 12 and the rotating shaft 11, thereby driving the connecting part 1 and clamping rod 2 to rotate, thereby quickly adjusting the angle of the bone plate and improving the applicability of the device.

[0025] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, the fixing device 5 includes an annular retaining frame 51, which is fixedly connected to the circumferential surface of the extension rod 9. A limiting shaft 52 is fixedly connected to the inner surface of the inner sleeve 14, and a retaining shaft 53 is slidably connected to the inner surface of the inner sleeve 14. The retaining shaft 53 is used to lock the extension rod 9 and the sleeve 12. The extension rod 9 drives the annular retaining frame 51 to fit onto the outer surface of the sleeve 12, thereby securing the sleeve 12 and improving installation stability. The retaining shaft 53, under the influence of spring force, pops out of the inner sleeve 14 and inserts into the outer shell 54, further improving the installation stability of the extension rod 9 and the sleeve 12, making the surgery more stable and safe. The fixing device 5 also includes an outer shell 54, which is fixedly connected to both sides of the sleeve 12. A push shaft 55 is slidably connected to the inner surface of the outer shell 54. A sliding shaft 56 is fixedly connected to the side of the push shaft 55 away from the retaining shaft 53. One end of 55 is fixedly connected to a pressure shaft 57. A through groove 58 is opened on the front side of the inner sleeve 14. A lever 59 is slidably connected to the inner surface of the through groove 58. An annular retaining frame 51 and the sleeve shaft 12 are sleeved on the circumferential surface. A spring is provided between the end of the retaining shaft 53 away from the outer shell 54 and the retaining shaft 53. The side of the push shaft 55 away from the sliding shaft 56 abuts against the retaining shaft 53. The sliding shaft 56 and the inner surface of the outer shell 54 are slidably connected. A spring is provided between the side of the pressure shaft 57 near the sliding shaft 56 and the outer shell 54. The rear end of the lever 59 is fixedly connected to the circumferential surface of the retaining shaft 53. When the device needs to be disassembled for maintenance and cleaning of the components, the pressure shaft 57 is pinched and brought close to the outer shell 54. The pressure shaft 57 drives the sliding shaft 56 and the push shaft 55 to slide in the outer shell 54 and approach the retaining shaft 53. When the push shaft 55 pushes the retaining shaft 53 back into the inner sleeve 14, the extension rod 9 and the sleeve shaft 12 lose their lock, which facilitates disassembly and improves the convenience of the device.

[0026] Working principle: After the extension rod 9 is inserted into the sleeve shaft 12, the extension rod 9 drives the annular retaining frame 51 to fit onto the outer surface of the sleeve shaft 12, thereby securing the sleeve shaft 12 and improving installation stability. During the insertion of the extension rod 9 into the sleeve shaft 12, it drives the inner sleeve 14 closer to the sleeve shaft 12. The inner sleeve 14 drives the limiting shaft 52 and the retaining shaft 53 closer to the sleeve shaft 12. When the exposed end of the retaining shaft 53 contacts the annular inclined groove 13, it retracts into the inner sleeve 14 through the guide of the inclined surface and compresses the spring. When the extension rod 9 and the inner sleeve 14 drive the retaining shaft 53 to align with the outer shell 54, The retaining shaft 53 is ejected from the inner sleeve 14 and inserted into the outer shell 54 by the spring force, which further improves the installation stability of the extension rod 9 and the sleeve shaft 12, making the operation more stable and safe. When it is necessary to disassemble the device for maintenance and cleaning of the components, pinch the pressure shaft 57 and bring it close to the outer shell 54. The pressure shaft 57 drives the sliding shaft 56 and the push shaft 55 to slide in the outer shell 54 and approach the retaining shaft 53. When the push shaft 55 pushes the retaining shaft 53 back into the inner sleeve 14, the extension rod 9 and the sleeve shaft 12 lose their lock, which facilitates disassembly and improves the convenience of the device.

[0027] Please see Figures 1-10 In another embodiment of the present invention, based on the above embodiments, the rinsing device 6 includes a spray gun 61, which is disposed on the side of the extension rod 9. The spray gun 61 is used to spray disinfectant solution onto the wound. A sliding frame 62 is fixedly connected to both sides of the extension rod 9. A clamping member 63 is slidably connected to the inner surface of the sliding frame 62. The clamping member 63 is used to clamp the spray gun 61. The spray gun 61 sprays disinfectant such as saline solution onto the wound for disinfection, preventing inflammation. Before disinfection, the spray gun 61 is inserted into the clamping member 63 and quickly fixed onto the extension rod 9, making the spraying process more stable and ensuring the disinfection effect. The clamping member 63 slides within the sliding frame 62 and extends out of the extension rod 9, making it convenient to insert the spray gun 61 into the clamping member 63, improving convenience. The rinsing device 6 also includes a support shaft 64, which is fixedly connected to both sides of the inner surface of the extension rod 9. A support frame is fixedly connected to one end of the support shaft 64 away from the inner surface of the extension rod 9. 65. A sliding column 66 is slidably connected to the inner surface of the support frame 65. A positioning groove 611 is provided on the inner side of the rear end of the support frame 65. Trapezoidal push blocks 67 are fixedly connected to both sides of the front end of the sliding column 66. An abutment shaft 68 is fixedly connected to the inner surface of the extension rod 9. A fixing member 69 is fixedly connected to the inner surface of the extension rod 9. A rotating gripper 610 is hinged to the inner surface of the fixing member 69. An elastic telescopic rod is provided between the front end of the sliding column 66 and the rear side of the abutment shaft 68. The rotating gripper 610... A torsion spring is provided at the hinge of the fixing member 69, and an elastic telescopic rod is provided between the clamping member 63 and the sliding sleeve 62. The inclined surface of the trapezoidal push block 67 abuts against the inclined surface of the clamping member 63. The rotating jaw 610 rotates and resets under the influence of the torsion spring and inserts into the positioning groove 611 to lock the sliding column 66. Then the clamping member 63 is released. The clamping member 63 is subjected to the pulling force of the elastic telescopic rod to tightly clamp the spray gun 61 between it and the extension rod 9, thereby improving the stability of the spray gun 61 installation.

[0028] Working principle: After the surgery, the spray gun 61 is activated and aimed at the wound. The spray gun 61 sprays saline and other disinfectant onto the wound to disinfect it and prevent inflammation. Before disinfection, the spray gun 61 is inserted into the clamp 63 and quickly fixed to the extension rod 9 to make the spraying process more stable and ensure the disinfection effect. After squeezing the pressure shaft 57, the push shaft 55 pushes the retaining shaft 53 to retract into the inner sleeve 14. The retaining shaft 53 drives the dial plate 59 in the through groove 58. Sliding and approaching the rear end of the rotating gripper 610, the final pusher 59 pushes the rotating gripper 610 to rotate and open within the fixing member 69, and pull it out from the positioning groove 611. At this time, the elastic force of the elastic telescopic rod pulls the sliding column 66 to slide forward within the support shaft 64 and the support frame 65. The sliding column 66 then drives the trapezoidal push block 67 to move forward. The trapezoidal push block 67 pushes the clamping member 63 to slide within the sliding groove sleeve 62 and extend the extension rod 9 through the guide of the inclined surface. This facilitates the spraying... The gun 61 is inserted into the clamping member 63, improving convenience. The pressure shaft 57 is released, causing the lever 59 to move away from the rotating jaw 610. At this time, the torsion spring at the hinge of the rotating jaw 610 and the fixing member 69 drives the rotating jaw 610 to reset through elastic force. Then, the clamping member 63 is pushed to partially retract into the extension rod 9. At this time, the clamping member 63 pushes the trapezoidal push block 67 to move backward through the inclined surface. The trapezoidal push block 67 then drives the sliding column 66 to slide backward. When the inclined surface at the rear end of the sliding column 66 contacts the rotating jaw 610, the rotating jaw 610 is guided by the inclined surface to rotate and open. At this time, the sliding column 66 continues to move backward and stops after contacting the fixing member 69. Then, the rotating jaw 610 is again affected by the torsion spring to rotate and reset and insert into the positioning groove 611 to lock the sliding column 66. Then, the clamping member 63 is released. The clamping member 63 is affected by the tension of the elastic telescopic rod to tightly clamp the spray gun 61 between it and the extension rod 9, thereby improving the stability of the spray gun 61 installation.
