Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, in particular to a medical orthopedic traction frame. Background Art

[0002] Orthopedic traction is an important treatment method in orthopedics. It uses the principle of action and reaction in mechanics to act on the affected limb through the traction of gravity to achieve the treatment goal. After the patient's leg is fractured, it needs to be repositioned and then plastered. The leg is suspended through traction to promote blood circulation and reduce swelling. The traction frame is used to assist the implementation of traction.

[0003] The patent with announcement number CN220938258U discloses an orthopedic traction frame, which belongs to the field of medical device technology. An orthopedic traction frame includes a connecting plate, one side of the connecting plate is respectively provided with a clamping mechanism and a winding roller, and one side of the connecting plate is provided with a driving member for driving the end of the winding roller, the top of the connecting plate is fixedly connected with an adjusting rod, the top of the adjusting rod is fixedly connected with a fixing block, and the inside of the fixing block is slidably connected with a crossbeam; the utility model can hang the patient's legs at different heights through the cooperation between the winding roller, the wire rope, the fixing frame and the supporting mechanism to promote blood circulation and swelling recovery. By setting in this way, the patient can adjust the height of the traction frame by himself, avoiding the need for others to assist in completing the action during the later adjustment of the traction frame, further improving the convenience during use, and it is more convenient to use.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] In order to use the wire rope to lift the patient's legs, one end of the wire rope is tied to the fixing frame to complete the connection between the wire rope and the fixing frame. However, during operation, the end of the wire rope may not be tied firmly due to operating errors. This may cause the connection between the wire rope and the fixing frame to loosen during the lifting process of the patient's legs, thereby causing the wire rope to accidentally separate from the fixing frame. When the wire rope separates from the fixing frame, the patient's legs will fall directly onto the bed, thereby causing damage to the patient's legs. In addition, when the patient's fracture site is accidentally touched or hit, secondary damage may be caused to the fracture site, affecting the patient's recovery.

[0047] Specifically, orthopedic traction is an important treatment method in orthopedics. It uses the principle of action and reaction in mechanics to act on the affected limb through the traction of gravity to achieve the purpose of treatment. After the patient's leg is fractured, it needs to be reset, and then plaster is applied, and the leg is suspended by traction to promote blood circulation and reduce swelling. The traction frame is used to assist in the implementation of traction. When the existing orthopedic traction frame is used, the patient's leg is placed on the support plate 7, and then the winding roller 46 is driven to rotate to reel or unwind the steel wire rope 47, so that the support plate 7 rises to suspend the patient's leg. However, in order to utilize When the wire rope 47 is used to lift the patient's legs, one end of the wire rope 47 is tied to the fixing frame to complete the connection between the wire rope 47 and the fixing frame. However, during operation, the end of the wire rope 47 may not be tied firmly, which may cause the connection between the wire rope 47 and the fixing frame to become loose during the lifting process of the patient's legs, thereby causing the wire rope 47 to separate from the fixing frame, and the patient's legs to fall directly onto the bed, thereby causing damage to the patient's legs. In addition, when the fracture site of the patient is accidentally touched or hit, secondary damage may be caused to the fracture site, affecting the patient's recovery.

[0048] Therefore, when the present embodiment is in use, according to the height to be lifted for the patient's legs, the motor 45 is started to drive the winding roller 46 to rotate. When the winding roller 46 rotates, the wire rope 47 can be wound or unwound. When the wire rope 47 lifts the lifting frame 44, the lifting frame 44 will drive the protruding rod 33 to rise. Moreover, since the protruding rod 33 and the lifting block 32 are in a sliding connection mode of key slot plugging, the protruding rod 33 will not rotate. When the upper end surface of the lifting block 35 contacts the lower end surface of the lifting block 32, the lifting block 32 starts to rise to lift the supporting plate 7. Moreover, when the lifting block 35 rises, the connecting rods 36 on both sides rotate to make the inserting blocks 37 slide on the L-shaped rods 38. The inserting blocks 37 on both sides are away from the grooves on both sides of the frame body 2. Moreover, when the upper end surface of the lifting block 35 fits the lower end surface of the lifting block 32, the distance between the two inserting blocks 37 is the smallest.

[0049] When the support plate 7 rises to a certain height, the horizontal position of the support plate 7 can be adjusted according to the position of the legs by using the extension and retraction of the telescopic rod 1 3, and then the patient's legs are placed on the support plate 7 to achieve the traction effect on the legs;

[0050] When the connection between the wire rope 47 and the lifting frame 44 is loose, and the wire rope 47 is separated from the lifting frame 44, the lifting frame 44 loses the upward pulling force, the spring 34 recovers, and the protruding block rod 33 slides downward. When the lifting block 35 moves downward, the connecting rods 36 on both sides rotate at the same time and drive the insert block 37 to slide on the L-shaped rod 38, so that the insert block 37 is inserted into the gap between the brake blocks 28 on both sides of the frame body 2. At this time, under the obstruction of the brake blocks 28, the lifting block 32 stops descending, and the supporting plate 7 also stops falling, thereby avoiding the situation where the patient's legs fall directly onto the bed when the wire rope 47 is suddenly separated from the lifting frame 44, thereby causing damage to the patient's legs, thereby improving safety;

[0051] When the patient's legs stay at a high position under the action of the brake, the braking position of the patient's legs may be detrimental to blood circulation and wound healing, and the legs need to be put down in time. When there is no medical staff near the patient and it is inconvenient for the patient to move the legs, the motor 3 40 can be started to rotate the threaded rod 3 41 to move the plug plate 42 up and down, so that the plug plate 42 is aligned with the groove block 43, and then the motor 1 9 is started to drive the threaded rod 49 to rotate, so that the groove frame 39 moves horizontally, and the plug plate 42 is inserted into the groove block 43, and then the motor 2 31 is started. The two-way threaded rod 29 is driven to rotate, so that the displacement plates 5 on both sides slide and move away from each other at the same time, so that the brake block 28 is moved out of the frame 2. At this time, the motor 3 40 is used to drive the threaded rod 3 41 to rotate, so that the plug plate 42 is lowered, and the supporting plate 7 is lowered to make the patient's legs fall slowly, thereby avoiding the patient's legs staying in a high place under the action of braking, because there are no medical staff near the patient and it is inconvenient for the patient to move the legs, resulting in the patient's legs always staying in the braking position, which is not conducive to the blood circulation of the legs and the healing of the wound;

[0052] Thus, by utilizing the anti-break brake type traction mechanism, when the end of the wire rope 47 is detached from the lifting frame 44, the support plate 7 can be braked, thereby preventing the patient's legs from falling directly onto the bed and causing damage to the patient's legs, thereby improving safety. In addition, when the patient's legs stay at a high place due to the action of the brake, the patient's legs can be slowly lowered, thereby preventing the patient's legs from always staying in the brake position due to the action of the brake, thereby being detrimental to the blood circulation of the legs and wound healing.

[0053] In this embodiment, Figure 1-Figure 4As shown, the left lower ends of the front and rear end surfaces of the rotating rod 11 are fixedly connected to the telescopic rod 2 15, the piston end of the telescopic rod 2 15 is fixedly connected to the fixing ring 16, one end surface of the fixing ring 16 is slidably connected to a plurality of sliders 19, one end of the slider 19 is fixedly connected to the guard plate 1 20, the two sides of the guard plate 1 20 are respectively fixedly connected to the guard plate 21 and the guard plate 3 22, the guard plate 21 and the guard plate 3 22 are plugged and slidably connected, the fixing ring 16 is sleeved and rotatably provided with a rotating ring 17, and the middle of the upper end of the rotating ring 17 is fixed A slide rod 24 is connected, a guide column 27 is inserted into the slide rod 24 and slidably connected thereto, one end of the guide column 27 is fixedly connected to a threaded block 23, the threaded block 23 is threadedly connected to a threaded rod 26, both ends of the threaded rod 26 are rotatably arranged on the fixed ring 16, the threaded block 23 is slidably connected to a limit rod 25, both ends of the limit rod 25 are fixedly connected to the fixed ring 16, a plurality of connecting rods 18 are rotatably arranged on one end surface of the rotating ring 17, and one end of the connecting rod 18 is rotatably connected to one end of the slider 19;

[0054] The right lower ends of the front and rear end surfaces of the rotating rod 11 are both rotatably provided with threaded barrels 13, the threaded barrel 13 is threadedly connected with a threaded rod 14, one end of the threaded rod 14 is fixedly connected to one side of a fixing ring 16, and one end of the threaded barrel 13 is sleeved and fixedly connected with a rotating wheel 12;

[0055] Specifically, when the existing orthopedic traction frame is in use, when the fracture site of the patient is accidentally touched or hit, it may cause secondary damage to the fracture site, affecting the patient's recovery. Therefore, when the patient's leg is lifted, the patient's leg passes through the through hole in the middle of the front and rear fixing rings 16. According to the position of the patient's leg fracture, the front or rear rotating wheel 12 is manually rotated to rotate the threaded cylinder 13, and the threaded rod 14 moves in the inner cavity of the threaded cylinder 13. The telescopic rod 2 15 is retracted to adjust the distance between the fixing ring 16 and the supporting plate 7, so that the fracture site is within the enclosure formed by the guard plate 1 20, the guard plate 21, and the guard plate 3 22. In addition, according to the thickness of the patient's leg, the threaded rod 2 26 is manually rotated to drive the threaded block 23 to move, so that the guide column 27 drives the slide groove The rod 24 and the rotating ring 17 rotate. When the rotating ring 17 rotates, the connecting rod 18 drives the slider 19 to slide on the fixed ring 16, so that the multiple guard plates 20 move radially to make them close to the patient's legs, and the guard plate 21 and the guard plate 3 22 slide relative to each other, so that the area of ​​the enclosure formed by the guard plate 1 20, the guard plate 21, and the guard plate 3 22 can be adjusted. Under the premise of not contacting the patient's legs, they are as close to the patient's legs as possible, so as to form a shield around the patient's legs to prevent the patient's fracture site from being accidentally touched or hit, which may cause secondary injury to the patient's fracture site. In addition, since the enclosure area is adjustable, the redundant area between the enclosure and the leg can be reduced to a large extent, further preventing foreign objects from entering the enclosure and causing impact on the patient's legs.

[0056] In this embodiment, Figure 1 As shown, a cushion 8 is provided on the inner side of the supporting plate 7;

[0057] Specifically, by providing a soft pad 8 on the inner side of the supporting plate 7, the comfort of the patient's legs is improved.

[0058] Working principle: according to the height to be lifted for the patient's legs, the motor 45 is started to drive the winding roller 46 to rotate. When the winding roller 46 rotates, the wire rope 47 can be wound or unwound. When the wire rope 47 lifts the lifting frame 44, the lifting frame 44 will drive the bump rod 33 to rise. Moreover, since the bump rod 33 and the lifting block 32 are in a sliding connection mode of key slot plugging, the bump rod 33 will not rotate. When the upper end surface of the lifting block 35 contacts the lower end surface of the lifting block 32, the lifting block 32 starts to rise to raise the supporting plate 7. Moreover, when the lifting block 35 rises, the connecting rods 36 on both sides rotate to make the plug block 3 7 slides on the L-shaped rod 38, and the plug blocks 37 on both sides are away from the grooves on both sides of the frame 2, and when the upper end surface of the lifting block 35 is in contact with the lower end surface of the lifting block 32, the distance between the two plug blocks 37 is the smallest; when the support plate 7 rises to a certain height, the horizontal position of the support plate 7 can be adjusted according to the position of the legs by using the telescopic rod 3 to extend and retract, and then the patient's legs are placed on the support plate 7. By providing a soft pad 8 on the inner side of the support plate 7, the comfort of the patient's legs is improved, and the traction effect on the legs can be achieved. When the patient's legs are lifted, the patient's legs pass through the through holes in the middle of the fixing rings 16 on the front and rear sides, according to The position of the patient's leg fracture is manually rotated, the front or rear wheel 12 is manually rotated to rotate the threaded cylinder 13, the threaded rod 14 moves in the inner cavity of the threaded cylinder 13, and the telescopic rod 2 15 is extended and retracted, so that the distance between the fixed ring 16 and the supporting plate 7 can be adjusted, so that the fracture site is within the enclosure formed by the guard plate 1 20, the guard plate 21, and the guard plate 3 22. In addition, according to the thickness of the patient's leg, the threaded rod 26 is manually rotated to drive the threaded block 23 to move, so that the guide column 27 drives the slide rod 24 and the rotating ring 17 to rotate. When the rotating ring 17 rotates, the connecting rod 18 drives the slider 19 to slide on the fixed ring 16, so that multiple guard plates are moved. The first guard plate 20 moves radially to be close to the patient's legs, and the second guard plate 21 and the third guard plate 22 slide relative to each other, so that the area of ​​the enclosure formed by the first guard plate 20, the second guard plate 21, and the third guard plate 22 can be adjusted. Under the premise of not touching the patient's legs, they are as close to the patient's legs as possible, so as to form a shield around the patient's legs to prevent the patient's fractured parts from being accidentally touched or hit, thereby causing secondary damage to the patient's fractured parts. In addition, since the enclosure area is adjustable, the redundant area between the enclosure and the legs can be reduced to a large extent, further preventing foreign objects from entering the enclosure and causing impact on the patient's legs;When the wire rope 47 is separated from the lifting frame 44, the lifting frame 44 loses the force of pulling upward, the spring 34 recovers, and the protruding rod 33 slides downward. When the lifting block 35 moves downward, the connecting rods 36 on both sides rotate at the same time and drive the inserting block 37 to slide on the L-shaped rod 38, so that the inserting block 37 is inserted into the gap between the brake blocks 28 on both sides of the frame body 2. At this time, under the obstruction of the brake blocks 28, the lifting block 32 stops descending, and the supporting plate 7 also stops falling, thereby avoiding the situation that the wire rope 47 is suddenly separated from the lifting frame 44, and the patient's legs fall directly onto the bed, thereby causing damage to the patient's legs, thereby improving safety; when the patient's legs stay at a high place under the action of braking, the braking position of the patient's legs may be not conducive to blood circulation and wound healing, and the legs need to be put down in time. When there is no medical staff near the patient and it is inconvenient for the patient to perform leg surgery When moving, the motor 3 40 can be started to rotate the threaded rod 3 41 to move the plug plate 42 up and down, so that the plug plate 42 is aligned with the groove block 43, and then the motor 1 9 is started to drive the threaded rod 49 to rotate, so that the groove frame 39 moves horizontally, and the plug plate 42 is inserted into the groove block 43, and then the motor 2 31 is started to drive the two-way threaded rod 29 to rotate, so that the displacement plates 5 on both sides slide and move away from each other at the same time, so that the brake block 28 is moved out of the frame body 2. At this time, the motor 3 40 is used to drive the threaded rod 3 41 to rotate, so that the plug plate 42 can be lowered, and the supporting plate 7 can be lowered to make the patient's legs fall slowly, thereby avoiding the patient's legs staying at a high place under the action of braking, because there is no medical staff near the patient and the patient himself is inconvenient to move the legs, resulting in the patient's legs always staying in the braking position, which is not conducive to the blood circulation of the legs and the healing of the wound.
