Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a detachable finger fracture traction tool. Background Technology

[0002] Currently, conservative treatment for finger fractures often involves using plaster casts, braces, or a combination of both for reduction and fixation. This type of fixation is complete, meaning it can only be removed after full recovery. Since the fixation period is at least 4 weeks, complete fixation affects the patient's ability to live independently (difficulty changing clothes, difficulty cleaning the skin), and if the traction rope accidentally comes loose during the fixation period, the patient cannot accurately adjust it themselves. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a wearable and detachable finger fracture traction tool to solve the problem that existing tools for traction fixation of finger bones cannot be freely worn and that patients cannot restore the loosened traction rope to the specified traction torque.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model discloses a removable finger fracture traction tool, comprising a flexible support plate. The back of the flexible support plate has several aluminum alloy support strips fixed to it. The front of the flexible support plate has several buckles connected to both sides of the front. One of the aluminum alloy support strips has a traction frame, one end of which is detachably connected to the aluminum alloy support strip. The other end of the traction frame has a finger bone fixation clip. A traction rope is provided between the finger bone fixation clip and the traction frame. One end of the traction rope is fixed to the finger bone fixation clip, and the other end is connected to the other end of the traction frame. A miniature tension gauge is provided on the traction rope.

[0006] Furthermore, the traction frame is L-shaped, and a number of adjustment holes are arranged side by side on one end of the traction frame connected to the traction rope. The end of the traction rope can be detachably connected to the adjustment holes.

[0007] Furthermore, the end of the traction frame is connected to the aluminum alloy support bar by screws.

[0008] Furthermore, the buckle includes a buckle ring and an elastic strap, one end of the buckle ring being fixed to one side of the flexible support plate, and one end of the elastic strap being fixed to the other side of the flexible support plate.

[0009] Furthermore, the flexible support includes an arm portion and a palm portion, the arm portion being longer than two-thirds of the patient's forearm, and the palm portion extending to the base of the patient's fingers.

[0010] Furthermore, the finger bone fixation clip includes a U-shaped clip with several hooks and loops, and a traction ring is provided on the outer side of the fingertip of the finger bone fixation clip, with a shrinkable traction rope fixed to the fixation ring.

[0011] Furthermore, the flexible support plate has a flexible liner on the surface that contacts the patient's skin.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this technical solution, the strap is fixed to the patient's arm, which makes it easy for the patient to put on and take off clothes and clean their skin;

[0014] 2. The miniature tension gauge and adjustment hole allow for intuitive adjustment and control of the traction force, and the adjustment method is simple, making it easy for patients to continue wearing the device after removing it.

[0015] 3. The traction frame is fixed to the aluminum alloy support bar with screws, which makes it easy to adjust the traction angle. At the same time, the setting of the adjustment hole makes it easy to adjust the traction force.

[0023] like Figures 1-3 As shown, a removable finger fracture traction tool includes a flexible support plate 1, such as a PVC transparent soft plate in the prior art. The back of the flexible support plate 1 is provided with several aluminum alloy support strips 5 (which can provide support and bend under external force). The aluminum alloy support strips 5 are fixed to the flexible support plate 1. The front of the flexible support plate 1 is provided with several buckles, which are connected to both sides of the front of the flexible support plate 1. One of the aluminum alloy support strips 5 is provided with a traction frame. One end of the traction frame is detachably connected to the aluminum alloy support strip 5. The other end of the traction frame is provided with a finger bone fixation clip. A traction rope 10 is provided between the finger bone fixation clip and the traction frame. One end of the traction rope 10 is fixed to the finger bone fixation clip, and the other end of the traction rope 10 is connected to the other end of the traction frame. A miniature tension gauge 11 is provided on the traction rope 10.

[0024] The working principle of the above technical solution is as follows:

[0025] First, the flexible support plate 1 is adjusted to fit the patient's arm by bending the aluminum alloy support bar 5. Then, the flexible support plate 1 is fixed to the patient's arm and palm by the buckle. Next, the finger bone fixation clip is clamped and fixed to the patient's fractured finger. Finally, the traction angle is adjusted by adjusting the angle and position of the traction frame. Finally, the traction rope 10 is fixed to the traction frame, and the reading of the miniature tension machine is observed to complete the traction of the patient's finger.

[0026] In one feasible embodiment, the traction frame is L-shaped and includes a connecting plate 6 and an adjusting plate 7. One end of the connecting plate 6 is connected to the aluminum alloy support bar 5, and the other end of the connecting plate 6 is fixedly connected to one end of the adjusting plate 7. Adjusting holes 8 are provided on the adjusting plate 7. Several adjusting holes 8 are arranged side by side on the end of the traction frame that is connected to the traction rope 10. The end of the traction rope 10 is detachably connected to the adjusting holes 8. The setting of the adjusting holes 8 can assist in adjusting the traction angle and also change the traction torque of the traction rope 10 to meet the traction requirements.

[0027] In one feasible embodiment, the end of the traction frame is connected to the aluminum alloy support bar 5 by screws 13. The screws 13 facilitate disassembly and fixing, and make it easy to adjust the angle of the traction frame.

[0028] In one feasible embodiment, the strap includes a buckle and an elastic band. One end of the buckle is fixed to one side of the flexible support plate 1, and one end of the elastic band is fixed to the other side of the flexible support plate 1. The elastic band can be understood as a Velcro strap, with one end fixed to the flexible support plate 1 and the other end passing through the buckle and then sticking to itself to fix it to the patient's arm.

[0029] In one feasible embodiment, the flexible support plate 1 includes an arm portion and a palm portion. The length of the arm portion is greater than two-thirds of the patient's forearm, and the length of the palm portion extends to the base of the patient's fingers, providing better support for the patient's arm and palm. It is also more stable when worn on the patient's arm. Of course, the traction frame is set on the aluminum alloy support strip 5 on the back of the palm portion. At the same time, the arm portion is provided with several arm straps 2, and the palm portion is provided with several palm straps 12. The actual configuration can be adjusted according to the specific situation, which will not be elaborated on here.

[0030] In one feasible embodiment, the finger bone fixation clip includes a U-shaped clip 3 with several hooks 4, and a traction ring 9 is provided on the outer side of the fingertip of the finger bone fixation clip, and a shrinkable traction rope 10 is fixed to the fixation ring.

[0031] In one feasible approach, the flexible support plate 1 has a flexible lining, such as a sponge layer, on the surface that contacts the patient's skin to reduce pressure on the patient's skin and improve wearing comfort.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
