Common traction methods include skin traction, skeletal traction and sling traction. Among them, skeletal traction is suitable for femoral fracture, cervical fracture, dislocation or muscle-rich fracture due to its large force and long duration.
[0003] Common skeletal traction includes femoral condyle traction and proximal tibial traction. Femoral condyle traction is a common method for treating thigh and femoral neck fractures. It uses steel needles or traction forceps to pass through the bone and directly act on the skeletal injury site to achieve reduction, fixation and rest. In specific operation, a Steinmann needle or Kirschner needle is inserted into the specified position, then one end of the rope is connected with the needle body, and the other end passes through the specified weight of the weight to form a gravitational traction process.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] The fracture treatment traction support device includes: a leg support plate 1 and a first support plate 2 and a second support plate 3 fixedly installed at the bottom of the leg support plate 1. A gantry frame 4 is fixedly installed on the top of the leg support plate 1. A first adjusting screw 5 is rotatably installed on the top of the gantry frame 4, with its bottom end extending into the gantry frame 4. A hollow lifting column 6 is threaded onto the first adjusting screw 5. A U-shaped mounting bracket 7 is fixedly installed at the bottom of the hollow lifting column 6. Two limiting columns are slidably installed on the top of the gantry frame 4. The bottom ends of both limiting posts are fixedly connected to the U-shaped mounting bracket 7, providing a limiting effect on the U-shaped mounting bracket 7. A cable guide spool 8 is fixedly installed inside the U-shaped mounting bracket 7. An angle disc 9 is fixedly sleeved on the cable guide spool 8, and a connecting rope 10 is wound around the cable guide spool 8. The connecting rope 10 is not wound around the cable guide spool 8 in a loop, but rather runs along the cable guide spool 8. That is, the cable guide spool 8 provides guidance and support for the connecting rope 10, and to ensure that the connecting rope 10 does not shift. A limiting disc is fixedly sleeved on the cable guide spool 8. The connecting rope 10 is located between the limiting disc and the angle disc 9 and is in contact with the limiting disc and the angle disc 9. A weighing device 11 is fixedly installed at one end of the connecting rope 10 near the first support plate 2. A U-shaped support 12 is fixedly installed at the bottom of the leg support plate 1, and a second adjusting screw 13 is rotatably installed inside it. The bottom end of the second adjusting screw 13 extends to the bottom of the U-shaped support 12. A connecting beam 14 is threaded onto the second adjusting screw 13. A downward pressure frame 15 is fixedly installed on the side away from the C-shaped support 12. The bottom of the downward pressure frame 15 is in contact with the weighing device 11. The connecting rope 10 passes through the downward pressure frame 15 and is movably connected to the downward pressure frame 15. A first limiting slide is opened on the first support plate 2. The connecting beam 14 passes through the first limiting slide and contacts its inner walls on both sides so that the two form a sliding relationship. This provides sliding space for the connecting beam 14 and also limits its movement, so that it can only move in a straight line.
[0026] In the above method, in order to make the weighing device 11 move only in a linear lifting manner, a cross platform is fixedly installed on the side of the first support plate 2 away from the second support plate 3. Four sliding columns distributed in a matrix are fixedly installed on the top of the cross platform. Two sliding plates are fixedly installed on both sides of the weighing device 11. The four sliding columns pass through the four sliding plates and are slidably connected to the corresponding sliding plates.
[0027] In this method, in order to restrain the patient's legs and prevent them from shifting, an internal cavity 16 is provided on the leg support plate 1, in which a bidirectional screw 17 is rotatably installed. Both ends of the bidirectional screw 17 extend outside the leg support plate 1. Two linkage plates 18 are threaded on the bidirectional screw 17. The tops of the two linkage plates 18 extend above the leg support plate 1 and are fixedly installed with leg guard plates 19. A second limiting slide is provided on the top of the leg support plate 1. The two linkage plates 18 pass through the second limiting slide and contact the inner walls on both sides. In addition, side baffles are fixedly installed on the top of the leg support plate 1. Both side baffles pass through the gantry 4.
[0028] In this method, in order to provide a routing guide for the connecting rope 10, a main connecting seat 20 is fixedly installed on the top of the leg support plate 1, a secondary connecting seat 21 is fixedly installed on one side of the main connecting seat 20, a first guide wheel 22 is fixedly installed on the main connecting seat 20, and a second guide wheel 23 is fixedly installed on the secondary connecting seat 21. The connecting rope 10 passes through the first guide wheel 22 and the second guide wheel 23.
[0029] The working principle of the fracture treatment traction support device provided by this utility model is as follows:
[0030] When traction treatment is required for the patient, first fix the first support plate 2 and the second support plate 3 to the hospital bed. Then, place the patient's legs on the leg support plate 1 for support and place them between the two side baffles. Then, in order to ensure that the legs are in the designated position and do not shift, the bidirectional screw 17 can be rotated clockwise. The two linkage plates 18 move closer to each other, and finally the two leg baffles 19 are used to restrict the patient's legs in the designated position.
[0031] Then, the Steinmann pin is inserted into the designated position on the patient's leg, and one end of the connecting rope 10 is connected to the Steinmann pin. At this time, the connecting rope 10 is in a taut state. Then, the traction angle of the connecting rope 10 is adjusted according to the actual traction angle. During adjustment, the first adjusting screw 5 is rotated directly. As the first adjusting screw 5 rotates, and under the restriction of the limiting column, the U-shaped mounting frame 7 rises with the cable guide 8. During the rising process, the patient's leg remains stationary. At this time, the connecting rope 10 begins to change angle on the angle plate 9. When the connecting rope 10 points to the corresponding angle mark on the angle plate 9, the rotation of the first adjusting screw 5 is stopped, thus completing the adjustment of the traction angle.
[0032] Then adjust the weight at the other end of the connecting rope 10. To adjust, simply turn the second adjusting screw 13 clockwise. The connecting beam 14 will then apply downward pressure to the lower frame 15. As the pressure increases, the value on the weighing scale 11 will gradually appear. When the required gravity value is reached, stop rotating the second adjusting screw 13. At this point, the traction weight adjustment is complete. Then, maintain the angle and weight for traction treatment.
[0033] Compared with related technologies, the fracture treatment traction support device provided by this utility model has the following beneficial effects:
[0034] This invention provides a traction support device for fracture treatment. By setting an angle disc 9 on the cable shaft 8, the traction angle of the connecting rope 10 can be observed in real time and can be adjusted to the required traction angle with relatively high precision. In addition, the downward pressure frame 15, which can be lowered, can provide a downward pressure to the weight-bearing device 11. The traction weight can be visualized by using the pressure of the weight-bearing device 11, so as to more accurately perform traction treatment with a specified weight on the patient. This allows medical staff to more accurately control relevant data when treating patients and improve the effect of traction treatment.
