Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a closed reduction device for finger fractures. Background Technology

[0002] Finger fractures are the most common type of hand fracture, also known as bamboo fractures. Because finger movements are delicate, tendons are complex, and blood vessels are located at the extremities, the key to treating finger fractures and ensuring successful patient recovery lies in properly reducing the fractured ends of the finger while maintaining finger function and peripheral blood supply.

[0003] Currently, closed reduction of finger fractures often employs manual reduction methods. One gauze strip is wrapped around the proximal end of the fractured finger, and another gauze strip is wrapped around the distal end. The fractured finger is closedly reduced by pulling the two gauze strips in opposite directions. However, due to the characteristics of the short tubular bone structure, the operating space is small during the reduction process, and it is difficult to generate an effective torque when applying force during reduction. The force is difficult to transmit to the fracture ends, resulting in poor reduction results. Utility Model Content

[0004] To improve the reduction effect, this application provides a closed reduction device for finger bone fractures.

[0005] The closed reduction device for finger bone fractures provided in this application adopts the following technical solution: A closed reduction device for finger fractures includes a left clamp body, a right clamp body, a finger gripper, an arc-shaped slide rod, a support rod, and a bracket. Two finger grippers are provided, each fixedly installed at the head end of the left and right clamp bodies. The left and right clamp bodies are hinged together by a pin. A connecting rod is vertically fixed to both the upper and lower ends of the pin. The arc-shaped slide rod is slidably mounted on the connecting rod, and a sliding hole is provided at one end of the arc-shaped slide rod. The support rod is slidably connected to the arc-shaped slide rod through the sliding hole. The bracket is fixedly installed at the end of the support rod near the finger gripper.

[0006] Optionally, each of the connecting rods has a threaded rod vertically fixedly installed at the end opposite to the pin shaft, and a threaded cap is threadedly installed on the threaded rod, the threaded cap abutting against the arc-shaped slide rod.

[0007] Optionally, multiple limiting holes are equidistantly provided on the outer wall of the support rod, and a rubber semicircular block is fixedly installed on the hole wall of the sliding hole, with the rubber semicircular block clamping inside the limiting hole.

[0008] Optionally, the bracket is semi-circular in shape.

[0009] Optionally, the included angle between the bracket and the support rod is 150° to 170°.

[0010] Optionally, anti-slip handles are fixedly installed at the tail ends of both the left and right clamps.

[0011] Optionally, both the finger gripper and the bracket are made of thickened silicone.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. The left and right clamps are used to hold the finger clamp at the distal end of the fracture. Then, the branch is pushed and placed against the near fracture end, acting as a traction device. At the same time, it provides a force fulcrum for subsequent reduction, increases the effective torque during the reduction process, and manipulates the left and right clamps to reduce the fractured and dislocated finger. Compared with manual traction, this method provides medical staff with sufficient operating space, while providing continuous and stable traction, force fulcrum and effective torque, thereby improving the reduction effect.

[0013] 2. The finger gripper is made of thickened silicone material, which provides greater friction and is better able to hold fractured or dislocated fingers. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0018] This application discloses a closed reduction device for finger bone fractures.

[0019] Reference Figure 1 and Figure 2 A closed reduction device for finger fractures includes a left clamp body 1, a right clamp body 2, a finger gripper 3, an arc-shaped slide bar 4, a support rod 5, and a bracket 6.

[0020] The finger gripper 3 is semi-circular in shape. There are two finger grippers 3, which can form a ring to hold the fractured and dislocated fingers. The two finger grippers 3 are fixedly installed at the head end of the left clamp body 1 and the head end of the right clamp body 2, respectively. The left clamp body 1 and the right clamp body 2 are hinged by a pin 7. The top and bottom ends of the pin 7 are vertically fixed with connecting rods 71. The arc-shaped slide rod 4 is slidably installed on the connecting rod 71. The end of the connecting rod 71 away from the pin 7 is vertically fixed with a threaded rod 72. The threaded rod 72 is threaded with a threaded cap 73. When the arc-shaped slide rod 4 does not need to slide, the operator screws on the threaded cap 73, causing the threaded cap 73 to fit tightly against the arc-shaped slide rod 4. The front end of the arc-shaped slide rod 4 has a sliding hole 41. The support rod 5 is slidably connected to the arc-shaped slide rod 4 through the sliding hole 41, so that the support rod 5 can be extended and shortened. The bracket 6 is fixedly installed at the end of the support rod 5 near the finger gripper 3. It is important to know that the support 6 is semi-circular.

[0021] The staff adjusts the angle of the support rod 5 using the curved slide bar 4 to accommodate the need for fracture reduction. The left clamp body 1 and the right clamp body 2 drive the finger clamp 3 to clamp the distal end of the fracture. Then, the support is pushed and placed against the near fracture end, acting as a traction device while providing a force fulcrum for subsequent reduction and enhancing the effective torque. Finally, the left clamp body 1 and the right clamp body 2 are manipulated to complete the fracture reduction operation.

[0022] The operator uses the left clamp 1 and right clamp 2 to hold the two finger clamps 3 at the tips of the fractured and dislocated fingers. Then, the operator slides the support rod 5, causing it to move the bracket 6 to the fractured and dislocated point of the finger. The support rod 5 then moves the arc-shaped sliding rod 4, allowing it to reduce the fractured and dislocated finger. It should be noted that if the support rod 5 is difficult to operate in one of the sliding holes 41, it can be moved to the other sliding hole 41.

[0023] After determining the length of the support rod 5, to prevent it from sliding during operation, multiple limiting holes 51 are equidistantly opened on the outer wall of the support rod 5 along its length. A rubber semicircular block 42 is fixedly installed on the wall of the sliding hole 41, clamping the rubber semicircular block 42 within the limiting hole 51. It should be noted that the rubber semicircular block 42 is made of rubber and has deformability, thus allowing the support rod 5 to slide within the sliding hole 41.

[0024] To facilitate the operation of the left clamp 1 and the right clamp 2 by the staff, anti-slip handles 8 are fixedly installed at the tail ends of both the left clamp 1 and the right clamp 2.

[0025] To prevent the finger gripper 3 and the bracket 6 from damaging the patient's fractured and dislocated fingers, both the finger gripper 3 and the bracket 6 are made of thickened silicone material.

[0026] It should also be noted that the angle between the support 6 and the strut 5 is 150° to 170°, allowing the support 6 to make better contact with the distal end of the patient's fractured and dislocated finger. In the embodiment of this application, the angle between the support 6 and the strut 5 is 160°.

[0027] The implementation principle of the closed reduction device for finger fractures in this application embodiment is as follows: The operator adjusts the angle of the support rod 5 through the arc-shaped sliding rod 4 to meet the needs of fracture misalignment reduction. The left clamp body 1 and the right clamp body 2 drive the finger clamp 3 to clamp the distal end of the fracture. Then, the support rod is pushed to push against the near fracture end, which acts like a traction device and provides a force fulcrum for subsequent reduction, enhancing the effective torque. Then, the left clamp body 1 and the right clamp body 2 are pried to complete the fracture reduction operation.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
