Description

Technical Field

[0001] This utility model relates to the field of traction frame technology, specifically an adjustable bone traction frame. Background Technology

[0002] Bone traction is one of the important surgical techniques for orthopedic surgeons to treat limb fractures. A puncture needle is inserted through the bone, and traction force is applied to the puncture needle through a bone traction bow. It can promote the reduction of fracture ends, allow the injured limb to rest and be fixed, prevent and correct deformities, and facilitate the observation and management of open wounds.

[0003] Traditional skeletal traction devices typically consist of a traction bow with a traction pin fixed in place, connected to a weighted sandbag via a rope for traction. However, this method has the following problems: when the rope is pulled downwards, its roughness can easily rub against the instep or toes, causing discomfort to the patient. Therefore, a skeletal traction frame was designed to address the aforementioned issues. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features.

[0030] Bone traction is one of the important surgical techniques for orthopedic surgeons to treat limb fractures. A puncture needle is inserted through the bone, and traction force is applied to the puncture needle through a bone traction bow. It can promote the reduction of fracture ends, allow the injured limb to rest and be fixed, prevent and correct deformities, and facilitate the observation and management of open wounds.

[0031] In related technologies, traditional skeletal traction devices typically consist of a traction bow fixing a traction pin, which is then connected to a weighted sandbag via a rope for traction. However, this method has the following problems: when the rope is pulled downwards, its roughness can easily rub against the instep or toes, causing discomfort to the patient.

[0032] To address some of the problems in related technologies, this application provides an adjustable bone traction frame. When installation is required, a puncture needle 11 is first inserted through the patient's tibia. Then, both ends of a U-shaped rod 12 are connected to the puncture needle 11. Next, an L-shaped plate 21 is placed under the patient's lower leg and secured with straps 22. The U-shaped rod 12 is then rotated so that one end overlaps inside the U-shaped plate 25. At this point, the spring 23 rebounds, pushing the push plate 24 to move. The push plate 24, in turn, moves the U-shaped plate 25, providing traction for the puncture needle and treating the patient. During treatment, there is no friction against the patient's skin, preventing discomfort. When the traction force of the U-shaped rod 12 needs adjustment, the threaded rod 33 can be rotated. During rotation, the threaded rod 33 contacts the moving plate 31, causing the moving plate 31 to move to one side. This movement compresses the spring 23, increasing its rebound force and better propelling the push plate 24 to adjust the traction force of the U-shaped rod 12.

[0033] This application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figures 1-4 This application provides an adjustable bone traction frame, including: a puncture needle 11 with a U-shaped rod 12 rotatably mounted on its outer side wall; a fixing assembly 2 is provided below the U-shaped rod 12, the fixing assembly 2 including: an L-shaped plate 21 disposed at the bottom of the U-shaped rod 12; a strap 22 fixedly disposed at the outer side wall of the L-shaped plate 21; a spring 23 disposed on one side of the L-shaped plate 21; a push plate 24 disposed at one end of the spring 23; and a U-shaped plate 25 disposed at the top of the push plate 24.

[0035] Specifically, the surface of the strap 22 is equipped with Velcro, which can be used to fix the patient's lower leg to the L-shaped plate 21 through adhesion. The principle of tibial transverse bone transport is mainly derived from a physiological phenomenon discovered by Ilizarov. This doctor found that by traction on the cortical bone, or by performing a certain osteotomy and traction on the bone, blood vessels, nerves, and other soft tissue structures inside the body will grow accordingly. Even without obvious attachment relationships, after such osteotomy and traction surgery, some growth factors in the surrounding area, such as vascular endothelial growth factor, will significantly increase, and these growth factors will promote the repair of surrounding soft tissues. Therefore, based on this principle, after performing tibial transverse bone transport surgery, the blood circulation reconstruction of the lower limb can be promoted during this process.

[0036] When installation is required, first insert the puncture needle 11 through the patient's tibia. Then connect both ends of the U-shaped rod 12 to the puncture needle 11. Next, place the L-shaped plate 21 under the patient's lower leg and secure it with the strap 22. Then rotate the U-shaped rod 12 so that one end of the U-shaped rod 12 overlaps inside the U-shaped plate 25. At this time, the spring 23 rebounds and pushes the push plate 24 to move. The push plate 24 drives the U-shaped plate 25 to move, which can traction the puncture needle and treat the patient. During the treatment, there will be no friction against the patient's skin, causing discomfort.

[0037] In some embodiments, the U-shaped rod 12 is a telescopic structure, and its surface is provided with adjusting bolts to adjust the length of the U-shaped rod 12.

[0038] When in use, the U-shaped rod 12 is a telescopic structure, and the leg length can vary depending on the patient's height. The length of the U-shaped rod 12 can be adjusted by rotating the adjusting bolt according to the patient's needs.

[0039] In some embodiments, the fixing component 2 further includes: one end of the crossbar 26 passes through the push plate 24 and is connected to the L-shaped plate 21.

[0040] The design of the crossbar 26 during use allows the push plate 24 to move stably, restricting the movement trajectory of the push plate 24 and making it less prone to deviation.

[0041] In some embodiments, the fixing component 2 further includes a baffle 27 disposed at one end of the crossbar 26.

[0042] During use, the push plate 24 can be prevented from disengaging from the crossbar 26 during its movement.

[0043] In some embodiments, the fixing component 2 further includes an arc-shaped plate 28 disposed on the top of the L-shaped plate 21.

[0044] When in use, the curved plate 28 is designed to support the patient's lower leg when the patient places their leg on the L-shaped plate 21, thus improving comfort.

[0045] In some embodiments, the push plate 24 is provided with an adjustment component 3, the adjustment component 3 including: a movable plate 31 through which the crossbar 26 passes and connected to the spring 23 on one side; a hole 32 is opened on the outer side wall of the push plate 24; a threaded rod 33 with one end passing through the hole 32 and the movable plate 31, and rotatably connected to the L-shaped plate 21, and threadedly connected to the movable plate 31.

[0046] When it is necessary to adjust the traction force of the U-shaped rod 12, the threaded rod 33 can be rotated. When rotating, the threaded rod 33 will contact the moving plate 31, thereby driving the moving plate 31 to move to one side. During the movement, the spring 23 is compressed, thereby increasing the rebound force of the spring 23, which better pushes the push plate 24 to adjust the traction force of the U-shaped rod 12.

[0047] In some embodiments, the spring 23 is sleeved on the outside of the threaded rod 33.

[0048] The design of the spring 23 sleeve ensures that the spring 23 will not bend when compressed, as the threaded rod 33 restricts the spring 23, thus better protecting the spring 23.

[0049] In some embodiments, the adjusting component 3 further includes a torque 34 disposed at one end of the threaded rod 33.

[0050] When in use, the knob 34 is designed to make it easy to grip and control the rotation of the threaded rod 33. At the same time, the groove on the surface of the knob 34 can increase friction when rotating, so that it is not easy to slip.
