Background
Orthopedics traction is a treatment method for preventing and correcting deformity by using external force to act on human bones to resist tension and retraction of soft tissues and resetting fracture displacement positions or dislocation joints. Orthopedic traction is divided into bone traction and skin traction. Both traction devices have a connector for attachment to a person's limb and a traction device for applying traction. The connecting piece for bone traction is a traction bow directly connected with bones; the connecting piece for skin traction is a traction sleeve which is sleeved on the limb and hoops the limb.
The orthopedic traction device is used for applying traction, and the structure of the conventional orthopedic traction device is shown in fig. 1 and comprises a bracket, pulleys, traction belts (ropes) and weights. The bracket is used for realizing the fixation of the orthopedic traction device and has various forms, for example, the bracket can be fixed on a bed stop at the back part of a sickbed, and can also be placed on the ground or the sickbed. The pulley is connected with the bracket. The traction belt bypasses the pulley, the traction belt bypasses the pulley and two ends of the traction belt are respectively connected with the connecting piece and the heavy object, and the pulley is used for converting the direction of the force, namely, the downward gravity of the heavy object is converted into the backward traction force which acts on the connecting piece and is then transmitted to bones.
The common orthopedic traction device has a simple structure, but the gravity is converted from one to one, namely, the gravity of the weight is as high as the traction force. The traction force commonly used in orthopaedics traction is about one tenth of the weight, namely, more than 5kg of weight is often needed by adults, and even 10kg of weight is needed by partial weight individuals. The heavy weight is adopted for traction, the heavy weight is inconvenient to move, and the damage caused by falling of the heavy weight is large.

Detailed Description
The utility model is further described below with reference to the drawings and the detailed description.
As shown in fig. 2, the orthopedic traction device comprises a bracket 1, a traction frame 2, a reminding device 3, a traction belt 4 and a weight 5; the traction frame 2 is positioned above the bracket 1, the traction frame 2 comprises a hinge seat 21, a rotating wheel 22, a weight rod 24 and a traction rod 23, the hinge seat 21 is connected with the bracket 1, the rotating wheel 22 is arranged in the left-right direction and is connected with the hinge seat 21, the weight rod 24 and the traction rod 23 are connected with the rotating wheel 22, the weight rod 24 faces to the rear, the traction rod 23 faces to the upper direction, and the weight rod 24 is longer than the traction rod 23; the reminding device 3 comprises a device frame 31 and two reminders 32, the device frame 31 is connected with the hinging seat 21 and sleeved outside the weight rod 24, the reminders 32 are connected with the device frame 31, the two reminders 32 are respectively positioned above and below the weight rod 24 and are spaced from the weight rod 24, and when the weight rod 24 contacts with the reminders 32, the reminders 32 can sound for reminding; the traction belt 4 is connected with a traction rod 23, and the weight 5 is connected with a weight rod 24.
The rotating wheel 22, the weight rod 24 and the traction rod 23 actually form a lever mechanism, and the traction force generated by the traction belt 4 is larger than the gravity of the weight 5 because the weight rod 24 is longer than the traction rod 23, so that larger traction force can be generated by adopting a lighter weight 5. If the length of the weight bar 24 is twice the length of the traction bar 23, the traction force is twice the length of the weight 5, and the larger the length difference between the weight bar 24 and the traction bar 23, the larger the force increase amplitude.
When the patient is subjected to fracture traction, the patient should theoretically lie on a sickbed without moving, but the patient is difficult to avoid moving after lying for a long time, and particularly the patient is also subjected to backward traction (along the direction of the tail of the sickbed). If the patient's limb moves back and forth, as in the prior art shown in fig. 1, the traction belt also moves with the patient, the weight moves up and down, and the traction force does not change. When the utility model is used, the limbs of a patient move forwards and backwards, the rotating wheel 22, the weight rod 24 and the traction rod 23 form a lever mechanism to swing, and when the swing angle is smaller, the traction force is not obviously changed, and adverse effects are avoided; however, if the limb movement amplitude of the patient is large, the swing amplitude of the lever mechanism is large, which can cause obvious change of traction force, and the traction force should be avoided. Therefore, the reminding device 3 is arranged, when the swing amplitude of the weight rod 24 is large, the weight rod 24 contacts with the reminder 32, and the reminder 32 sounds to remind. At this time, the limbs of the patient can be moved back to the original position, the lever mechanism can be reset, and the traction force can be restored.
The specific construction of reminder 32 is simple. For example, a travel switch may be used to control the buzzer, with the travel switch and buzzer being powered by a lithium battery. The weight lever 24 contacts the travel switch, and the travel switch controls the buzzer to start sounding reminding.
As described above, the larger the length difference between the weight bar 24 and the traction bar 23, the larger the force increase amplitude, and conversely the smaller the traction force increase amplitude. The present utility model preferably has weight bar 24 adjustable in length. So that the weight is not changed. Traction force can also be adjusted by adjusting the length of the weight bar 24, which is more convenient.
The length of the weight bar 24 may be adjusted in a specific manner as shown in fig. 3, the weight bar 24 includes a sleeve 241, a weight hanging screw 242, and a first locking nut 243, the sleeve 241 is connected to the wheel 22, the weight hanging screw 242 is screwed to the sleeve 241, and the first locking nut 243 is connected to the weight hanging screw 242 and abuts against the sleeve 241.
When the length of weight bar 24 is adjusted. The weight 5 is removed, the first lock nut 243 is loosened, the weight hanging screw 242 is rotated, the weight hanging screw 242 is moved axially, and the length of the weight rod 24 is changed. After the adjustment in place, the locking nut 243 is tightened and the weight 5 is then connected to the weight bar 24.
When the orthopedic traction is performed, the limbs of the patient are not necessarily horizontal and can be lifted. The present utility model also rotates the lever mechanism to adjust the orientation of the traction bar 23 such that the traction belt 4 is generally co-directional with the patient's limb and the traction bar 23 is substantially perpendicular to the traction belt 4. So that the traction force is also in the same direction as the limb of the patient. After adjustment of the lever mechanism, the direction of the weight bar 24 is also changed. The position of the reminder 3 is also changed at this time. The height of the reminder device 3 is thus preferably adjustable.
As shown in fig. 4, the height-adjustable concrete mode of the reminding device 3 is that a connecting transverse plate 211 is arranged on the hinge seat 21; the reminding device 3 comprises an adjusting screw 33, the adjusting screw 33 penetrates through the connecting transverse plate 211, two second locking nuts 34 are connected to the adjusting screw 33, and the two second locking nuts 34 are respectively located above and below the connecting transverse plate 211 and are attached to the connecting transverse plate 211.
The two second locking nuts 34 are loosened, the adjusting screw 33 is moved up and down, the reminder 32 is adjusted to a proper position, and the second locking nuts 34 are tightened to complete the adjustment.
In order to accommodate different positions of the patient's limb, the utility model may preferably also be height-adjustable with respect to the traction frame 2, in addition to the pivoting lever mechanism described above. So that the traction force can be more suitable for the difference of the height and the angle of the limbs of the patient, and the traction force is also in the same direction with the limbs of the patient.
The specific mode of the height-adjustable traction frame 2 can be shown as fig. 5, and the orthopedic traction device comprises a locking bolt 6; the bracket 1 is provided with two guide holes 11 and two long holes 12, the long holes 12 are arranged in one-to-one correspondence with the guide holes 11, and the long holes 12 extend to the guide holes 11 from the surface of the bracket 1; the traction frame 2 comprises two guide rods 25, and one guide rod 25 is inserted into one guide hole 11; the locking bolt 6 passes through the long hole 12 and is in threaded connection with the guide rod 25, and the locking bolt 6 is screwed down to enable the guide rod 25 to be tightly attached to the hole wall of the guide hole 11.
The locking bolt 6 is screwed down to enable the guide rod 25 to be tightly attached to the hole wall of the guide hole 11, and the height change of the traction frame 2 is avoided by virtue of the friction force between the guide rod 25 and the hole wall of the guide hole 11. The locking bolt 6 is loosened. The traction frame 2 is adjusted to a proper height, and the locking bolt 6 is screwed down again to finish the adjustment.
The specific way of connecting the traction belt 4 to the traction frame 2 is preferably as follows: the traction frame 2 is provided with a traction hook 231, the traction belt 4 is provided with a plurality of traction belt holes 41 which are arranged at intervals along the length direction of the traction belt 4, and the traction belt 4 is hung on the traction hook 231 through any traction belt hole 41. Thus, when it is desired to adjust the angle of the lever mechanism, a different pulling strap hole 41 can be selected to hang on the pulling hook 231. After the patient's limb is displaced, the patient may not be moved back to the home position, but a different traction strap hole 41 may be selected to hang on the traction hook 231, allowing the lever mechanism to be reset.
The weight 5 may be connected to the weight bar 24 in such a manner that a weight hook 244 is provided on the weight bar 24, and the weight 5 is hung on the weight hook 244.
