Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a medical fracture reduction clamp. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology, and pathology of the musculoskeletal system, and uses drugs, surgery, and physical methods to maintain and develop the normal shape and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries and diseases has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and polio have decreased significantly, while injuries caused by traffic accidents have increased significantly. Common orthopedic diseases include patellar fracture, ulnar nerve injury, congenital coxa vara, and finger replantation. After a fracture, reduction forceps are generally used to reduce the broken bone, and it is fixed with plates, screws, etc. When performing fracture reduction surgery on fracture patients, the two ends of the fracture need to be aligned and repositioned. The two sides must be aligned first and then gently pulled together. Therefore, reduction forceps are needed to reduce the bone fragments.

[0003] Currently used reduction forceps, such as Allis and Kocher, are straight forceps. After clamping, it is difficult to place the bone plate directly between the teeth. It is often necessary to use Kirschner wires for temporary fixation before releasing the forceps and placing the bone plate. If the Kirschner wires are not firmly fixed, the fracture is prone to re-displacement, increasing the operation time and patient trauma. Furthermore, when using reduction forceps, it is necessary to use a blood vessel to aspirate blood from the bleeding point. The blood vessel is connected to a negative pressure device for blood aspiration. When using the blood vessel, the doctor needs to hold it continuously and adjust its position at any time. During long operations, this can easily lead to doctor fatigue, making it easy to lose control of the blood vessel and increasing the risk of surgery. Therefore, we propose a medical fracture reduction forceps. Summary of the Invention

[0004] The purpose of this invention is to provide a medical fracture reduction clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a reset clamp body, the end of which is arc-shaped, and the reset clamp body is arc-shaped. A fixing plate is fixedly connected to one side of the reset clamp body. A suction tube is slidably connected inside the fixing plate. A rotating assembly for driving the suction tube to rotate is connected to the top of the fixing plate. The rotating assembly includes an annular rack rotating on the top of the fixing plate. Four support rods are fixedly connected to the top of the annular rack. The tops of the four support rods are fixedly connected to the same fixing ring. A limiting plate is fixedly connected inside the fixing ring. The inner surface of the limiting plate is slidably connected to the inner surface of the suction tube. The rotating assembly for driving the annular rack to rotate is connected to the top of the fixing plate.

[0006] In a preferred embodiment of the medical fracture reduction forceps of the present invention, the rotating assembly includes a gear rotating on the top of the fixing plate, a fixing rod fixedly connected to the top of the gear, a connecting plate rotatably connected to the outer surface of the fixing rod, a guide rod fixedly connected to the inside of the fixing plate, a rotating rod rotatably connected to the outer surface of the guide rod, the top end of the rotating rod rotatably connected to the connecting plate, a thin wire fixedly connected to the bottom end of the rotating rod, and a moving assembly for pulling the thin wire connected to the front side of the reduction forceps body.

[0007] In a preferred embodiment of the medical fracture reduction forceps of the present invention, a torsion spring is sleeved on the outer surface of the guide rod, and the two ends of the torsion spring are respectively fixedly connected to the guide rod and the fixing plate.

[0008] In a preferred embodiment of the medical fracture reduction clamp described in this invention, the rotating rod is telescopic.

[0009] In a preferred embodiment of the medical fracture reduction forceps of the present invention, the movable component includes a rotating plate that rotates on the front side of the forceps body, a connecting rod that is slidably connected to the inner surface of the rotating plate, and the bottom end of the connecting rod being fixedly connected to the thin wire.

[0010] In a preferred embodiment of the medical fracture reduction clamp of the present invention, a pressure plate is fixedly connected to the top of the connecting rod, and the top of the pressure plate is provided with anti-slip texture.

[0011] In a preferred embodiment of the medical fracture reduction forceps of the present invention, a support spring is sleeved on the outer surface of the connecting rod, and the two ends of the support spring are respectively fixedly connected to the pressure plate and the rotating plate.

[0012] In a preferred embodiment of the medical fracture reduction forceps of the present invention, a limiting tube is fixedly connected to the side wall of the forceps body, and the inner surface of the limiting tube is in movable contact with the thin wire.

[0013] In a preferred embodiment of the medical fracture reduction clamp of the present invention, the inner surface of the fixation plate is rotatably connected to a bolt, the end of the bolt is rotatably connected to a snap-fit ​​plate, and the snap-fit ​​plate is in active contact with the aspiration tube.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This device clamps the bone fragment with a reduction forceps body. The forceps body is designed in an arc shape, allowing it to pass directly through the bone plate, increasing the ease of operation and the firmness of fracture reduction. It also facilitates the direct passage of the plate through the forceps, avoiding displacement when fixing the fracture fragment with Kirschner wires and placing the plate. Furthermore, it avoids bone fragment displacement caused by temporary fixation with Kirschner wires followed by secondary clamping with the forceps body. The arc-shaped end of the forceps body prevents the tips of the straight forceps (such as Allis or Kocher) from piercing the bone cortex, which helps protect smaller long bones (such as the clavicle) and avoids injury to the patient. This improves the practicality of the reduction forceps and protects the patient.

[0016] 2. The device drives the rotating component to rotate through the moving component, which in turn causes the blood collection tube to swing, thereby drawing blood around the bleeding point. This avoids excessive blood collection from a single point for an extended period, achieving uniform blood collection from the bleeding point, reducing the need for driving the electric equipment, and minimizing vibration of the blood collection tube. By controlling whether the blood collection tube draws blood, stable blood collection can be achieved. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Reference Figures 1-5 The present invention proposes a technical solution comprising a reduction clamp body 1. The reduction clamp body 1 can be of different sizes to suit the application needs of long bones in different locations, including large sizes for the femur and tibia, medium sizes for the humerus and radius / ulna, and small sizes for the clavicle or hands and feet. The end of the reduction clamp body 1 is arc-shaped. By clamping the bone fragment with the reduction clamp body 1, the arc shape facilitates the placement of a steel plate in the gap of the bone fragment, avoiding the displacement of the bone fragment caused by temporary fixation with Kirschner wires followed by secondary clamping with the reduction clamp body 1. Furthermore, the arc shape of the reduction clamp body 1, with its end either arc-shaped or flat, avoids a sharp point, thereby preventing the end of the reduction clamp body 1 from piercing the bone cortex and causing harm to the patient. A fixing plate 2 is fixedly connected to one side of the repositioning forceps body 1. A suction tube 3 is slidably connected inside the fixing plate 2. A rotating assembly for driving the suction tube 3 to rotate is connected to the top of the fixing plate 2. The rotating assembly includes an annular rack 4 rotating on the top of the fixing plate 2. Four support rods 5 are fixedly connected to the top of the annular rack 4. The same fixing ring 6 is fixedly connected to the top of the four support rods 5. A limiting plate 7 is fixedly connected inside the fixing ring 6. The inner surface of the limiting plate 7 is slidably connected to the inner surface of the suction tube 3. When the annular rack 4 rotates, it drives the support rods 5 to rotate, thereby causing the fixing ring 6 to rotate, which in turn drives the limiting plate 7 to rotate, thus rotating the suction tube 3. This prevents the suction tube 3 from drawing blood from the bleeding point for a long time. The rotating assembly for driving the annular rack 4 to rotate is connected to the top of the fixing plate 2.

[0027] In this embodiment, the rotating assembly further includes a gear 9 rotating on the top of the fixed plate 2. A fixed rod 10 is fixedly connected to the top of the gear 9. A connecting plate 11 is rotatably connected to the outer surface of the fixed rod 10. A guide rod 12 is fixedly connected to the inside of the fixed plate 2. A rotating rod 13 is rotatably connected to the outer surface of the guide rod 12. The top end of the rotating rod 13 is rotatably connected to the connecting plate 11. A thin wire 15 is fixedly connected to the bottom end of the rotating rod 13. By pulling the thin wire 15, the rotating rod 13 is pulled to rotate on the guide rod 12, thereby stretching the torsion spring 14, thereby driving the connecting plate 11 to move, thereby driving the gear 9 to rotate on the fixed plate 2, thereby realizing the rotation of the ring rack 4. When the thin wire 15 is released, the rotating rod 13 is reset by the elasticity of the torsion spring 14, driving the connecting plate 11 to move, thereby making the gear 9 rotate back to its original position. A moving assembly for pulling the thin wire 15 is connected to the front side of the reset clamp body 1.

[0028] In this embodiment, a torsion spring 14 is further sleeved on the outer surface of the guide rod 12, and the two ends of the torsion spring 14 are respectively fixedly connected to the guide rod 12 and the fixing plate 2.

[0029] In this embodiment, the rotating rod 13 is further telescopic. When the rotating rod 13 drives the connecting plate 11 to move, the rotating rod 13 will be compressed, thereby facilitating the movement of the connecting plate 11 and avoiding motion interference between the connecting plate 11 and the rotating rod 13.

[0030] In this embodiment, the moving component further includes a rotating plate 16 that rotates on the front side of the reset clamp body 1. A connecting rod 17 is slidably connected to the inner surface of the rotating plate 16. The bottom end of the connecting rod 17 is fixedly connected to the thin wire 15. When the index finger presses the pressure plate 18, it causes the connecting rod 17 to slide inside the rotating plate 16, thereby compressing the support spring 19 and causing the thin wire 15 to move. When the pressure plate 18 is released, the pressure plate 18 moves upward to its original position through the elastic release of the support spring 19.

[0031] In this embodiment, a pressure plate 18 is fixedly connected to the top of the connecting rod 17. The top of the pressure plate 18 is provided with anti-slip texture. The anti-slip texture on the pressure plate 18 allows the index finger to press the pressure plate 18 stably and move, preventing it from slipping and causing the repositioning forceps body 1 to shake and cause secondary injury to the patient.

[0032] In this embodiment, a support spring 19 is further sleeved on the outer surface of the connecting rod 17. The two ends of the support spring 19 are fixedly connected to the pressure plate 18 and the rotating plate 16, respectively. Through the elasticity of the support spring 19, an upward force is generated on the pressure plate 18, thereby making the pressure plate 18 stably set on the rotating plate 16.

[0033] In this embodiment, a limiting tube 20 is further fixedly connected to the side wall of the reset clamp body 1. The inner surface of the limiting tube 20 is in contact with the thin wire 15. The limiting tube 20 limits and protects the thin wire 15, preventing the thin wire 15 from interfering with the operation of the reset clamp body 1 and facilitating the movement of the thin wire 15.

[0034] In this embodiment, the inner surface of the fixing plate 2 is further rotatably connected with a bolt 21, and the end of the bolt 21 is rotatably connected with a snap-fit ​​plate 8. The snap-fit ​​plate 8 is in active contact with the suction tube 3. The bolt 21 rotates to drive the snap-fit ​​plate 8 to move, thereby facilitating the adjustment of the suction tube 3. The length of the suction tube 3 can be adjusted according to the depth of the bleeding port, which increases the applicability of the suction tube 3 and improves its practicality.

[0035] The working principle and usage process of this invention: When in use, the blood collection tube 3 is moved into the limiting plate 7, and then the bolt 21 is rotated to drive the snap-fit ​​plate 8 to move, thereby fixing the blood collection tube 3. Then the doctor holds the clamp ring of the repositioning forceps body 1 with his index and middle fingers, and then uses the repositioning forceps body 1 to clamp the bone block.

[0036] When the wound bleeds, pressing the pressure plate 18 with the index finger causes the connecting rod 17 to slide within the rotating plate 16, thereby moving the thin thread 15, which in turn pulls the rotating rod 13 to rotate on the guide rod 12, causing the torsion spring 14 to stretch, which in turn moves the connecting plate 11, causing the gear 9 to rotate on the fixed plate 2, which in turn causes the ring rack 4 to rotate, which in turn causes the support rod 5 to rotate, which in turn causes the fixed ring 6 to rotate, which in turn causes the limiting plate 7 to rotate, thus rotating the suction tube 3.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
