Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary instruments, and in particular relates to a simple medical traction device. Background Art

[0002] A traction device is a medical device used to reduce fractures, especially to correct shortening and displacement of fractures. For patients with foot fractures, a traction device is needed to stabilize the fracture ends to facilitate healing of the fracture site.

[0003] The existing traction device is shown in the patent document with patent authorization announcement number CN 214596128 U, which discloses a traction belt for protecting the patient's lower limbs. A traction rope is provided on the pedal, and a bedside traction frame is provided on one side of the pedal. The bedside traction frame includes a U-shaped frame, and a first hook is symmetrically provided at the top of the U-shaped frame. A connecting rod is provided at the bottom of the U-shaped frame, and a pulley frame is provided at one end of the connecting rod. A plurality of pulleys are provided in the pulley frame. The traction rope is inserted through the U-shaped frame and is arranged in contact with one of the pulleys, and a weight is provided at one end of the traction rope. The bedside traction frame is connected to the bedside frame through the first hook. The gravity of the weight exerts a downward pulling force on the traction rope, thereby pulling the patient's foot to achieve the effect of correcting the shortening and displacement of the fracture.

[0004] When the above-mentioned traction device structure is used for foot fracture reduction treatment, a weight is used to pull the traction rope to tighten the bandage to correct the foot fracture. Although this structure has a certain pulling force on the foot bandage, the weight and the traction rope are in an active state during the process of pulling the foot bandage. When the patient's foot moves, the weight and the traction rope will be pulled out of place, affecting the effect of foot correction and reduction. Therefore, technical improvements are needed to address this problem. Utility Model Content

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0024] like Figures 1 to 3As shown, this embodiment discloses a simple medical traction device, including an insertion bracket 1 connected to an operating bed, a swing frame 2 for adjusting the traction direction of the strap, a rotating roller 3 for rotating and adjusting the strap, and a ratchet mechanism 4 for limiting the unidirectional rotation of the rotating roller 3. A transversely extending cross bar 11 is provided on the top of the insertion bracket 1, and the swing frame 2 is sleeved and connected to the cross bar 11. The swing frame 2 can slide along the length direction of the cross bar 11 and rotate along the axial direction of the cross bar 11. The swing frame 2 is provided with a locking mechanism 5 for locking the swing frame 2 to the cross bar 11. The rotating roller 3 spans across both sides of the swing frame 2 and is rotatably connected to the swing frame 2. The ratchet mechanism 4 is located on one side of the swing frame 2. The ratchet mechanism 4 is connected to the end of the rotating roller 3 corresponding to the protruding end of one side of the swing frame 2, and the other end of the rotating roller 3 is provided with a handle 6. When the traction device of this embodiment is used, it is only necessary to insert and fix the insertion bracket 1 on the operating bed, adjust the swing frame 2 to a suitable position and angle, lock and fix it through the locking mechanism 5, and fix the strap bound to the foot for tightening correction and reduction to the rotating roller 3. The ratchet mechanism 4 limits the rotating roller 3 to be able to rotate in the tightening direction of the strap and prevents it from rotating in the loosening direction of the strap. The staff rotates the rotating roller 3 through the handle 6 to tighten the strap so that the patient's foot is kept in a suitable correction and reduction position. During the stretching and traction process, under the joint action of the ratchet mechanism 4 and the locking mechanism 5, the traction position and traction angle of the traction device will not change, and the length of the strap will not change due to the force exerted by the patient's foot. Therefore, the purpose of correcting fracture reduction can be better achieved. As the treatment progresses, the length and tension of the strap can be adjusted by gradually rotating the rotating roller 3 through the handle 6. It is very convenient to use and has a good effect on the reduction and correction of foot fractures.

[0025] As a preferred embodiment, the outer wall of the rotating roller 3 is provided with a pull ring 31 for connecting the strap, and the pull ring 31 and the outer wall of the rotating roller 3 are combined to form a strap hole 32 for the strap to pass through. By providing the pull ring 31 on the outer wall of the rotating roller 3 to form the strap hole 32, when the strap is connected to the rotating roller 3, it is sufficient to directly connect the pull ring 31, which makes the strap connection more convenient. When the rotating roller 3 rotates, the pull ring 31 drives the strap to rotate and adjust, and the adjustment accuracy is higher.

[0026] As a preferred embodiment, the ratchet mechanism 4 includes a ratchet 41 and a pawl 42, wherein the ratchet 41 is fixedly connected to the end of the rotating roller 3, and the pawl 42 is movably connected to one side of the swing frame 2, and the ratchet 41 is movably engaged with the pawl 42; when the traction device is in use, if it is necessary to limit the rotating roller 3 to rotate in one direction, the pawl 42 is moved to make the pawl 42 engage with the ratchet 41, and at this time, after the rotating roller 3 is rotated and adjusted to a certain angle, it will not rotate in the opposite direction due to the pulling of the patient's foot, and the pulling force of the bandage on the patient's foot is better maintained to ensure the therapeutic effect of the patient's foot. When the rotating roller 3 needs to rotate freely in both directions, the pawl 42 is moved to separate the pawl 42 from the ratchet 41, and the unidirectional rotation restriction of the rotating roller 3 is released. At this time, the rotating roller 3 can rotate freely in both directions, and the bandage can be loosened by rotating the rotating roller 3.

[0027] As a preferred embodiment, a connecting through hole is radially opened at the other end of the rotating roller 3, and the handle 6 includes a rod 61 and heads 62 located at both ends of the rod 61, the outer diameter of the rod 61 is smaller than the aperture of the connecting through hole, the maximum outer diameter of the head 62 is larger than the aperture of the connecting through hole, the rod 61 is movably connected to the connecting through hole, and the head 62 limits the movability of the rod 61 in the connecting through hole. When the rotating roller 3 rotates, the rod 61 of the handle 6 can slide along the axial direction of the connecting through hole, so that the operation of the handle 6 is more flexible.

[0028] As a preferred embodiment, the swing frame 2 is provided with a movable through hole for connecting with the cross bar 11, the cross bar 11 passes through the movable through hole, the aperture of the movable through hole is larger than the outer diameter of the cross bar 11, the locking mechanism 5 includes a locking bolt, the swing frame 2 is provided with a threaded hole radially connected to the movable through hole, and the locking bolt is connected to the threaded hole. When the locking bolt is tightened along the threaded hole and pressed against the outer wall of the cross bar 11, the swing frame 2 and the cross bar 11 are relatively fixed under the action of the pressing force of the locking bolt. When the locking bolt is withdrawn from the bolt hole, the locking effect between the swing frame 2 and the cross bar 11 is released, and the swing frame 2 can slide along the length direction of the cross bar 11 and rotate along the axial direction of the cross bar 11, so that the swing frame 2 can be adjusted to a suitable position and angle.

[0029] As a preferred embodiment, the plug-in bracket 1 further includes an extension rod 12 and a vertical rod 13, one end of the extension rod 12 is connected to one end of the cross bar 11, the other end of the extension rod 12 is connected to one end of the vertical rod 13, the extension rod 12 is perpendicular to the cross bar 11, the vertical rod 13 is perpendicular to the horizontal plane, the angle between the extension rod 12 and the horizontal plane is in the range of 30° to 50°, the extension rod 12 and the vertical rod 13 are on the same vertical plane, and the angle between the extension rod 12 and the vertical rod 13 is in the range of 120° to 150°. The structure of the plug-in bracket 1 can make the tractor more convenient to operate when in use, and avoid collision between the handle 6 and the plug-in bracket 1 when rotating.
