Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a traction and fixation device for bone surgery. Background Art

[0002] Intertrochanteric fractures of the femur are common in the elderly. Due to the rich blood supply of the trochanteric region, fractures rarely fail to heal, but hip valgus is very likely to occur. There are many complications caused by long-term bed rest in elderly patients. When treating intertrochanteric fractures, conventional means require the insertion of steel nails into the fracture site for positioning, and on the outside of the patient's fracture, a traction fixation device is generally required to fix the patient's legs accordingly to avoid secondary injuries to the patient during treatment. For example, the patent with publication number CN215960204U discloses an intertrochanteric fracture traction fixation device for bone surgery instruments, including a waist fixing base and a leg traction fixing base, the waist fixing base is fixedly connected with a docking arc plate, the leg traction fixing base is fixedly connected to the bottom of the waist fixing base, the side of the leg traction fixing base is rotatably connected with a leg traction arc splint, the leg traction arc splint and the leg traction fixing base are fixed by bolts, and a tightening mechanism is provided on the side wall of the leg traction fixing base. When the orthopedic surgical instrument intertrochanteric fracture traction fixation device is used, the legs can be clamped by the leg traction arc splint and the leg traction fixation base, and the device can be fixed on the waist by the waist fixation base. However, different patients have different heights, and the positions they need to be fixed may also be different. Therefore, the above device may not be suitable for different patients.

[0003] To this end, the utility model provides a bone surgery traction fixation device. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a traction and fixation device for orthopedic surgery, comprising a first plate body 1 and a second plate body 2, wherein a splint 3 is installed on one side of the first plate body 1 close to the second plate body 2, a first buffer pad 6 is fixed on the splint 3, a second buffer pad 7 is fixed on the second plate body 2, a first telescopic rod 8 is rotatably matched with one side of the second plate body 2, a strap 11 is installed at one end of the first telescopic rod 8, a limiting component is installed on the second plate body 2, and the limiting component corresponds to the first telescopic rod 8.

[0022] In this embodiment, a plurality of second telescopic rods 10 are installed between the first plate body 1 and the second plate body 2, and the two ends of the second telescopic rods 10 are fixedly connected to the first plate body 1 and the second plate body 2 respectively. A plurality of sliding rods 4 are slidably fitted on the first plate body 1, and one end of the sliding rod 4 is fixedly connected to the splint 3. A threaded rod 5 is threadedly fitted on the first plate body 1, and one end of the threaded rod 5 is rotatably connected to the splint 3.

[0023] Specifically, when the patient's legs need to be clamped, the first plate body 1 and the second plate body 2 are placed on both ends of the patient's legs, and then the length of the second telescopic rod 10 is adjusted. After the length of the second telescopic rod 10 is fixed, the threaded rod 5 is rotated so that the threaded rod 5 pushes the splint 3 close to the second plate body 2, so that the patient's legs can be clamped and fixed.

[0024] A groove 9 is provided on the side of the second plate body 2 away from the first plate body 1, and the groove 9 corresponds to the first telescopic rod 8. One end of the first telescopic rod 8 is fixedly connected to the binding strap 11, and a rotating shaft 16 is fixed to the other end of the first telescopic rod 8, and the rotating shaft 16 is rotatably fitted in the groove 9. A limiting plate 15 is installed on the side of the second plate body 2 away from the first plate body 1, and the limiting plate 15 is located at one end of the groove 9. A plurality of bolt holes 14 are provided on the side of the second plate body 2 away from the first plate body 1, and a limiting rod 12 is installed on the side of the second plate body 2 away from the first plate body 1, and a plurality of bolts 13 are installed in the limiting rod 12, and the bolts 13 correspond to the bolt holes 14.
