Description

Technical Field

[0001] The utility model relates to the technical field of ankle joint training, in particular to a hip spica brace capable of ankle pump movement. Background Art

[0002] Ankle pump exercise is a simple and effective lower limb functional exercise method that mainly promotes blood circulation and lymph flow through flexion, extension and circular movements of the ankle joint, and has multiple benefits.

[0003] In the field of orthopedics, the hip spica brace is an important auxiliary treatment tool, widely used in the conservative treatment and postoperative rehabilitation of conditions such as femoral neck fractures, intertrochanteric fractures, hip dislocations, and hemiarthroplasty. Traditional hip spica braces primarily connect the injured limb to the trunk through the connection between its components, thereby preventing displacement of the fracture ends caused by limb movement and providing a basic condition for fracture healing. However, this device can only be used in a fixed position. During the long-term wearing of the brace, patients often face problems such as poor blood circulation in the lower limbs, muscle atrophy, and joint stiffness. In particular, the risk of deep vein thrombosis in the lower limbs is significantly increased.

[0004] Therefore, those skilled in the art have proposed a hip spica brace capable of ankle pumping to solve the problems raised in the background art. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a hip spica brace capable of ankle pump movement, so as to solve the problems that the hip spica brace in the prior art can only be used in a fixed manner and long-term use will cause poor blood circulation in patients.

[0006] A hip spica brace capable of ankle pumping motion comprises a calf frame, a connecting rod mounted on the top of the calf frame, a thigh frame mounted on the top of the connecting rod, a connecting flexible shaft mounted on the bottom of the calf frame, a foot pad mounted on the end of the calf frame away from the calf frame, and connecting straps mounted on the outer side walls of the foot pad, the calf frame, and the thigh frame;

[0007] Training mechanisms, the training mechanisms being arranged at both ends of the foot pad;

[0008] a locking member disposed between the calf frame and the foot pad;

[0009] The training mechanism includes a storage box, which is fixedly connected to both sides of the foot pad. The inner wall of the storage box is rotatably connected to a connecting shaft. The inner wall of the storage box is also fixedly connected to a limiting sleeve. A connecting torsion spring is fixedly connected between the limiting sleeve and the connecting shaft. A pull rope is also wrapped around the outer wall of the connecting shaft.

[0010] Preferably, a limiting member is further provided at the top of the storage box, and the limiting member includes a conical sleeve, which is fixedly connected to the top of the storage box, the top of the conical sleeve is fixedly connected to an outer screw sleeve, the top of the outer screw sleeve is threadedly connected to an inner screw sleeve, a plurality of adjustment grooves are provided on the inner sides of the conical sleeve and the outer screw sleeve, and a plurality of limiting washers are fixedly connected to the inner side wall of the conical sleeve.

[0011] Preferably, the pull rope is slidably connected to the inner side wall of the inner screw sleeve and the conical sleeve. When the inner screw sleeve rotates downward, it squeezes the conical sleeve to allow the limiting washer to limit the pull rope.

[0012] Preferably, the top end of the drawstring is fixedly connected with a connecting pull ring, and the connecting pull ring is ring-shaped for easy connection with a finger.

[0013] Preferably, the locking member includes a connecting sleeve, the connecting sleeve is fixedly connected to the outer wall of the foot pad, the inner wall of the connecting sleeve is snap-connected with a connecting block, the outer wall of the calf frame is fixedly connected with a fixing strap, and the end of the fixing strap away from the calf frame is fixedly connected to the connecting block.

[0023] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] As attached Figure 1 To the attached Figure 6 As shown:

[0025] Embodiment 1: The present invention provides a hip spica brace capable of ankle pumping, comprising a calf frame 1, a connecting rod 11 being mounted on the top of the calf frame 1, a thigh frame 12 being mounted on the top of the connecting rod 11, a connecting flexible shaft 13 being mounted on the bottom end of the calf frame 1, a foot pad 14 being mounted on the end of the calf frame 1 away from the calf frame 1, and connecting straps 15 being mounted on the outer side walls of the foot pad 14, the calf frame 1, and the thigh frame 12;

[0026] Training mechanisms, which are provided at both ends of the foot pad 14;

[0027] A locking member, the locking member being arranged between the calf frame 1 and the foot pad 14;

[0028] The training mechanism includes a storage box 2, which is fixedly connected to both sides of the foot pad 14. The inner side wall of the storage box 2 is rotatably connected to a connecting shaft 21. The inner side wall of the storage box 2 is also fixedly connected to a limiting sleeve 22. A connecting torsion spring 23 is fixedly connected between the limiting sleeve 22 and the connecting shaft 21. A pull rope 24 is also wrapped around the outer side wall of the connecting shaft 21. A limiting member is also provided at the top of the storage box 2, and the limiting member includes a tapered sleeve 25. The tapered sleeve 25 is fixedly connected to the top of the storage box 2. The top of the tapered sleeve 25 is fixedly connected to an outer screw sleeve 26. The top of the outer screw sleeve 26 is threadedly connected to an inner screw sleeve 29. A plurality of adjustment grooves 27 are provided on the inner sides of the tapered sleeve 25 and the outer screw sleeve 26. A plurality of limiting washers 28 are fixedly connected to the inner side wall of the tapered sleeve 25.

[0029] Specifically, by setting the connecting torsion spring 23, the storage box 2 can be limited, and the storage box 2 can be easily reset after it is rotated.

[0030] The pull rope 24 is slidably connected to the inner side wall of the inner screw sleeve 29 and the conical sleeve 25. When the inner screw sleeve 29 rotates downward, it squeezes the conical sleeve 25 to allow the limiting washer 28 to limit the pull rope 24. The top end of the pull rope 24 is fixedly connected to a connecting pull ring 210. The connecting pull ring 210 is ring-shaped and convenient for connection with fingers.

[0031] Specifically, by setting the connecting pull ring 210, it can be conveniently connected to the fingers, so that the fingers can pull the storage box 2 and the foot pad 14 to rotate through the pull rope 24, thereby helping patients to train.

[0032] The locking part includes a connecting sleeve 3, which is fixedly connected to the outer wall of the foot pad 14. The inner wall of the connecting sleeve 3 is snap-connected with a connecting block 32. The outer wall of the calf frame 1 is fixedly connected with a fixing strap 31. The end of the fixing strap 31 away from the calf frame 1 is fixedly connected to the connecting block 32.

[0033] Specifically, by the engagement between the connecting sleeve 3 and the connecting block 32 , the foot pad 14 and the calf frame 1 can be conveniently limited in position or contact, thereby facilitating adjustment.

[0034] As can be seen from the above, when this device needs to be used, if training is required, first buckle the connecting block 32 to disengage the connecting block 32 from the connecting sleeve 3, and let the connecting sleeve 3 release the limit on the connecting block 32, so that the connecting flexible shaft 13 can move freely, then hold the connecting pull ring 210 with your fingers, and then pull the connecting pull ring 210 to slide out with the pull rope 24. After pulling the connecting pull ring 210 to the appropriate length, use the other hand to rotate the inner screw sleeve 29 to rotate the inner screw sleeve 29 downward on the outside of the outer screw sleeve 26. At this time, the inner screw sleeve 29 will squeeze the tapered sleeve 25, allowing the tapered sleeve 25 to move inward, allowing the adjustment slot 27 to limit the pull rope 24, making it convenient for the user to pull.
