Description

Technical Field

[0001] The present invention belongs to the technical field of medical traction equipment, and in particular relates to a traction device for orthopedic care. Background Art

[0002] Orthopedic traction utilizes the principle of action and reaction in mechanics to stretch the affected limb to treat orthopedic conditions such as fractures and dislocations. Traction is primarily used for cervical fractures, pelvic fractures, femoral neck fractures, intertrochanteric fractures, femoral shaft fractures, and unstable tibia and fibula fractures. Its objectives include relieving tension and retraction in the soft tissues at the fracture and dislocation site, reducing the fracture or dislocation, immobilizing the affected limb to reduce local irritation and the spread of inflammation, maintaining functional limb position, stabilizing fracture ends to relieve pain and facilitate healing, and correcting and preventing joint deformities caused by muscle contractures.

[0003] Traction on fractures may cause sequelae such as nonunion, malunion, and traumatic arthritis. Malunion of fractures is caused by improper traction treatment, which leads to displacement of the fracture ends, poor alignment, angulation, rotation, or overlapping malunion. Therefore, imposing a certain degree of restriction on the leg traction process is a way to solve malunion. Summary of the Invention

[0044] When in use, the pull rope should be tied to the connecting rod 16 first, and then the two limiting rings 15 are put on the two ends of the traction needle 1. The spiral connecting ring on the connecting rod 16 is tightened, and the pressure plate 23 contacts the skin around the traction needle 1. When the connecting rod 16 rebounds, the pressure plate 23 is squeezed against the leg skin, and the sliding rod 24 passes through the gap between the limiting ring 15 and the traction needle 1. The sliding rod 24 drives the push rod 25 to move horizontally, so that the bottom of the deflection lever 28 is pressed, thereby causing the deflection lever 28 to deflect; the splints 1 29 and 2 30 on both sides of the leg are simultaneously subjected to the pressure from the deflection lever 28, resulting in deflection, thereby realizing the two sets of splints 1 29 and splints. 2.30 pairs of limiting pressing on leg muscles; during traction, it is necessary to adjust the direction of pulling the traction rope according to the angle of the patient's leg fracture. In order to ensure that the traction area splint 27 can be parallel to the leg, the sliding block 21 can be made to slide in the rotating groove 20, and the horizontal relationship between the traction area splint 27 and the leg can be adjusted so that the traction area splint 27 can fit the leg better when clamped; when the traction area splint 27 clamps the leg, the screw 17 is directly rotated to fix the limiting ring 15 relative to the traction needle 1. When the traction area splint 27 does not fit on the leg, the limiting ring 15 can be moved closer to the leg by pressing the connecting rod 16 until the traction area clamps the leg. The plate 27 is clamped on the leg, and then the screw 17 is tightened; in order to ensure that the broken leg bone will not grow dislocated under traction, the leg needs to be limited so that the leg can only stretch and grow in a fixed direction during traction. Therefore, the leg side plate 7 will also move toward the leg at the same speed as the limiting ring 15 approaches the leg; when the horizontal bar 9 on the leg side plate 7 contacts the leg, the horizontal bar 9 will be squeezed by the legs and move away from the legs, and the push rod 10 passes through the leg side plate 7 and presses one end of the feedback lever 11, so that the covering splint 8 deflects and squeezes the patient's leg, and the triangular protrusion 12 on the surface of the push rod 10 slides During the process, it comes into contact with the ridge limit block 13, and under the push of the triangular protrusion 12, the ridge limit block 13 slides back and forth in the block slide groove 14 until the covering splint 8 is completely clamped on the outside of the leg; when the equipment needs to be removed from the leg, the ridge limit block 13 is pulled to both sides along the block slide groove 14, so that the triangular protrusion 12 and the ridge limit block 13 are no longer in contact, and the torsion spring between the leg side plate 7 and the covering splint 8 separates the covering splint 8 from the leg, and the screw 17 is rotated in the opposite direction to separate the screw 17 from the traction needle 1, and then the limiting ring 15 is pulled in the direction away from the traction needle 1, thereby removing the connecting rod 16 from the traction needle 1.
