Description

Technical Field

[0001] The present invention belongs to the technical field of medical traction devices, and specifically refers to a traction device for orthopedic nursing. Background Art

[0002] Orthopedic traction utilizes the principle of action and reaction in mechanics to pull the affected limb to treat orthopedic diseases such as fractures and dislocations. Traction is mainly used for cervical fractures, pelvic fractures, femoral neck fractures, intertrochanteric fractures, femoral shaft fractures, and unstable tibiofibular fractures, etc. Its purposes include relieving the tension and retraction of soft tissues at the fracture and dislocation sites, reducing local irritation and inflammation spread by immobilizing the affected limb, maintaining the functional position of the limb, stabilizing the fracture ends for analgesia and facilitating fracture healing, and correcting and preventing joint deformities caused by muscle contracture, etc.

[0003] When traction is performed on a fracture, sequelae such as nonunion, malunion, and traumatic arthritis may occur. Among them, fracture malunion is caused by improper traction treatment, resulting in displacement of the fracture ends, poor alignment, and angular, rotational, or overlapping malunion. Therefore, imposing a certain degree of restriction during the leg traction process is a way to solve malunion. Summary of the Invention

[0004] In view of the above situation, in order to prevent malformation during the healing process of leg bones, the present invention provides a traction device for orthopedic nursing. By means of one-way extrusion to cause the deflection of the lever structure, the device realizes the function of wrapping and limiting the leg when it approaches the leg, thereby further restricting the direction of leg bone healing and avoiding malformation of the bone fracture area.

(2) Utilizing the pressure when the cross bar presses against the leg, the rotation of the feedback lever is realized, so that the covering splint clamps the leg. Under the contact and collision between the triangular protrusion and the convex rib limiting block, the fixed position of the feedback lever in space is realized, thereby further fixing the position of the covering splint on the leg.

[0029] The anti-displacement device 4 for the fracture site includes a leg automatic tightening and limiting structure 5 and a post-tightening limiting device 6.

The leg side plate 7 is snap-fitted and slidably mounted on the side wall of the traction limiting device 2. The covering splint 8 is hinged to the leg side plate 7. A card slot is provided on the leg side plate 7. The cross bar 9 is snap-fitted and slidable in the card slot on the leg side plate 7. The first push rod 10 is fixedly connected to the cross bar 9.

The feedback lever 11 is hinged to the covering splint 8.

[0031] The post-tightening limiting device 6 includes a triangular protrusion 12, a convex rib limiting block 13, and a block chute 14. The triangular protrusion 12 is fixedly provided on the side wall of the first push rod 10. The block chute 14 is fixedly provided on the side wall of the leg side plate 7. The convex rib limiting block 13 slides along the block chute 14. The triangular protrusion 12 is in contact connection with the convex rib limiting block 13. The side wall of the convex rib limiting block 13 is provided with an inclined surface structure.

[0032] A spring is connected between the convex rib limiting block 13 and the block chute 14. A handle is provided on the convex rib limiting block 13.

[0033] The leg side plate 7 and the covering splint 8 are connected by a torsion spring. The deflection lever 28 and the limiting column 22 are connected by a torsion spring.

[0034] A chute is provided on the side wall of the limiting ring 15. The leg side plate 7 is snap-fitted and slidable in the chute on the side wall of the limiting ring 15.

[0035] During specific use, first tie the pull rope to the connecting rod 16, then slip two limiting rings 15 onto both ends of the traction needle 1. The spiral connecting ring on the connecting rod 16 tightens, and the pressing plate 23 contacts the skin around the traction needle 1. When the connecting rod 16 rebounds, the pressing plate 23 squeezes the skin of the leg. The sliding rod 24 passes through the gap between the limiting ring 15 and the traction needle 1, and the sliding rod 24 drives the second push rod 25 to move horizontally, thereby pressing the bottom of the deflection lever 28, causing the deflection lever 28 to deflect; the first splints 29 and the second splints 30 on both sides of the leg are simultaneously subjected to the pressure from the deflection lever 28 and deflect, thereby realizing the limiting pressing of the leg muscles by the two groups of first splints 29 and second splints 30; during traction, it is necessary to adjust the pulling direction of the traction rope according to the angle of the patient's leg bone fracture. To ensure that the splint 27 in the traction area can be parallel to the leg, the sliding block 21 can be made to slide in the rotation groove 20 to adjust the horizontal relationship between the splint 27 in the traction area and the leg, so that the splint 27 in the traction area can fit more closely to the leg when clamping; when the splint 27 in the traction area clamps the leg, directly rotate the screw 17 to fix the limiting ring 15 relative to the traction needle 1. When the splint 27 in the traction area does not fit on the leg, the connecting rod 16 can be pressed to make the limiting ring 15 move closer to the leg until the splint 27 in the traction area clamps on the leg, and then the screw 17 is tightened; to ensure that the fractured leg bone does not grow out of place during traction, it is necessary to limit the leg so that the leg can only extend and grow in a fixed direction during traction. Therefore, when the limiting ring 15 moves closer to the leg, the leg side plate 7 also moves towards the leg at the same speed; when the cross bar 9 on the leg side plate 7 contacts the leg, the cross bar 9 will be squeezed by the two legs and move away from the two legs. The first push rod 10 passes through the leg side plate 7 and presses one end of the feedback lever 11, causing the covering splint 8 to deflect and squeeze the patient's leg. During the sliding process of the triangular protrusion 12 on the surface of the first push rod 10, it contacts the convex rib limiting block 13. Under the pushing action of the triangular protrusion 12, the convex rib limiting block 13 reciprocates in the block chute 14 until the covering splint 8 completely clamps on the outside of the leg; when it is necessary to remove the device from the leg, pull the convex rib limiting block 13 along the block chute 14 to both sides, so that the triangular protrusion 12 and the convex rib limiting block 13 are no longer in contact. The torsion spring between the leg side plate 7 and the covering splint 8 separates the covering splint 8 from the leg. Rotate the screw 17 in the reverse direction to separate the screw 17 from the traction needle 1, and then pull the limiting ring 15 away from the traction needle 1 to remove the connecting rod 16 from the traction needle 1.
