Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an orthopedic limb traction device. Background Art

[0002] Traction is a commonly used technique in orthopedics. It is a method of reduction and fixation of fractures and joint dislocations. It is divided into skin traction and bone traction. Bone traction is the use of bone round needles or stainless steel needles to directly penetrate the hard part of the bone. The steel needle is pulled by the gravity of the heavy object to achieve traction on the fractured limb, which can effectively overcome muscle tension and correct deformities caused by overlapping fractures or joint dislocations.

[0003] Currently, when orthopedics performs bone traction on the foot, doctors need to use tools such as hand drills or electric drills to insert the traction needle into the bone. However, doctors cannot ensure the horizontality when moving the tool, resulting in needle deviation. When needle deviation occurs, the needle needs to be withdrawn and re-punctured, which prolongs the operation time, increases the harm to the patient, and increases the patient's pain.

[0004] Therefore, there is an urgent need to provide an orthopedic limb traction device that can automatically thread the needle and ensure the needle movement level. Utility Model Content

[0005] In order to overcome the disadvantages of the current orthopedic foot bone traction operation that when doctors use tools such as hand drills or electric drills to insert the traction needle into the bone, the tool cannot be moved horizontally, resulting in needle deviation, the utility model provides an orthopedic limb traction device that can automatically insert the needle and ensure the horizontal movement of the needle.

[0011] Preferably, a support rod for fixing the ventilation pipe is fixedly connected to the second arc-shaped limiting plate.

[0012] Preferably, a limiting seat for limiting the position of the traction rope is provided on the mounting seat of the directional wheel.

[0013] Preferably, an anti-wear sleeve is provided on the directional roller of the directional wheel.

[0014] Compared with the prior art, the utility model has the following technical effects: 1. The push rod is driven downward by the operation of the cylinder, so that the push rod pushes the traction steel needle forward to penetrate the foot, thereby realizing automatic needle threading. At the same time, the guide rod guides the traction steel needle to keep the traction steel needle moving horizontally to avoid puncture deviation.

[0015] 2. By rotating the second screw rod, the connecting frame drives the lifting frame to move up and down, thereby adjusting the height of the foot to form counter-traction, reduce the pressure of gravity on the injured part, and facilitate venous and blood return to reduce swelling.

[0016] 3. Pull the two annular baffles together and then fix them by attracting the first magnet to seal the protective tube to protect the weights, so as to prevent the weights from falling when they are hit or shaken.

[0017] 4. Clamp the legs by the first arc-shaped limiting plate and the second arc-shaped limiting plate, and then continuously press the inflatable balloon ball to inflate the annular airbag, so that the annular airbag expands and fills the gap between the legs and the first arc-shaped limiting plate and the second arc-shaped limiting plate, thereby achieving effective fixation and preventing the legs from moving or rotating and affecting the needle threading of the foot.

A guide frame 7 is fixedly connected to the rear side of the lifting frame 2 by means of screw connection. A first screw rod 8 is rotatably provided on the guide frame 7. A mounting frame 9 is threadedly provided on the first screw rod 8. The mounting frame 9 slides left and right on the guide frame 7. A cylinder 10 is installed on the upper part of the mounting frame 9. A push rod 11 is provided on the movable rod of the cylinder 10. The push rod 11 is inclined to facilitate the movement of the steel needle during movement. A guide rod 901 is fixedly connected to the front side of the mounting frame 9 by means of welding. A traction steel needle 12 slides through the guide rod 901. The push rod 11 is driven downward by the operation of the cylinder 10, so that the push rod 11 can push the traction steel needle 12 to move, thereby realizing automatic needle threading.

[0029] When in use, the patient's foot is moved onto the lifting frame 2, and then the first screw 8 is rotated to make the mounting frame 9 drive the traction steel needle 12 to move left and right to find the puncture position. Subsequently, the cylinder 10 is started, and the cylinder 10 drives the push rod 11 to move downward, so that the push rod 11 pushes the traction steel needle 12 forward to penetrate into the patient's foot, thereby realizing automatic needle insertion. At the same time, the guide rod 901 guides the traction steel needle 12 to keep the traction steel needle 12 moving horizontally to avoid puncture deviation. After the traction steel needle 12 is inserted, the traction rope 4 is tied to the two ends of the traction steel needle 12, and the weight 6 is placed on the placement frame 5, and the patient's foot is pulled by the gravity of the weight 6 to achieve traction.

A connecting frame 15 is threadedly provided on the second screw 14. The connecting frame 15 is connected to the lifting frame 2. Rotating the second screw 14 can drive the lifting frame 2 to move up and down to achieve lifting.

[0032] During traction, the second screw rod 14 can be rotated to make the connecting frame 15 drive the lifting frame 2 to move up and down, so as to adjust the height of the patient's foot to form counter-traction, reduce the pressure of gravity on the injured part, and facilitate venous and blood return to reduce swelling.

[0033] See also Figure 4 A protective tube 16 is provided on the placement rack 5, and an annular baffle 17 symmetrically distributed frontally and rearward is rotatably provided inside the protective tube 16. First magnets 18 are embedded on the two annular baffles 17. Under the magnetic force of the first magnets 18, the two annular baffles 17 can be fixed after rotating and contacting.

[0034] After the weight 6 is placed, the two annular baffles 17 are pulled close together, and the first magnet 18 is attracted to fix the protective tube 16 to close the weight 6 to protect the weight 6 and prevent the weight 6 from falling when it is hit or shaken.

[0035] See also Figure 5 A first arc-shaped limiting plate 19 is slidingly arranged in the middle of the lifting frame 2, and a second arc-shaped limiting plate 20 is hinged on the first arc-shaped limiting plate 19. The first arc-shaped limiting plate 19 and the second arc-shaped limiting plate 20 are both embedded with a second magnet 2001. When in use, the first arc-shaped limiting plate 19 and the second arc-shaped limiting plate 20 are fixed by the magnetic force of the second magnet 2001, so that the first arc-shaped limiting plate 19 and the second arc-shaped limiting plate 20 can clamp the patient's legs for support. An annular airbag 21 is commonly arranged inside the first arc-shaped limiting plate 19 and the second arc-shaped limiting plate 20, and a ventilation tube 23 is connected and communicated with the annular airbag 21. An inflatable balloon ball 24 is installed on the ventilation tube 23. Pressing the inflatable balloon ball 24 can inflate the annular airbag 21 to fix the patient's legs. A support rod 22 for fixing the ventilation tube 23 is fixed to the second arc-shaped limiting plate 20 by screw connection.

[0036] Before puncture, open the second arc-shaped limiting plate 20 and place the patient's leg into the first arc-shaped limiting plate 19, then close the second arc-shaped limiting plate 20. Under the action of the second magnet 2001, the first arc-shaped limiting plate 19 and the second arc-shaped limiting plate 20 are fixed to each other to clamp the patient's leg for support. Then, the inflatable balloon ball 24 is continuously pressed to inflate the annular airbag 21, so that the annular airbag 21 expands and fills the gap between the patient's foot and the first arc-shaped limiting plate 19 and the second arc-shaped limiting plate 20, thereby achieving effective fixation of the patient's leg and preventing the leg from moving or rotating, which affects the needle insertion of the foot.
