Embodiment 1

[0036] Please refer to Figure 1-5 , a femoral shaft fracture fixation and traction brace for infants provided by the present invention includes a backboard 3 , a first lower limb fixing frame 1 and a second lower limb fixing frame 2 three main parts. Wherein, the backboard 3 is used to make the infant lean against it, and the two sides of the upper part of the backboard 3 gather inwardly to form two gathering boards 101, which can better fix the upper body of the infant, and the outer surface of the gathering board on one side is A lock ring 4 is arranged on the top, and a lock belt 5 is arranged on the outer surface of the gathering plate on the other side. The free end surface of the lock belt 5 is provided with a Velcro mother surface layer, and the rest is a Velcro surface layer (not marked in the figure). ), when the lock belt 5 passes through the lock ring 4 and is folded back, the mother surface layer and the child surface layer can be bonded to form a lock structure, ...

Embodiment 2

[0045] The difference between this embodiment and the first embodiment lies in that the structures of the first connection mechanism and the second connection mechanism adopted are different. Please also refer to Figure 6-8 , in the present embodiment, the first connection mechanism includes a third connection plate 17, and one end of the third connection plate 17 is connected to the back plate 3 (the structure of this end can be a triangular plate in the embodiment, and arc-shaped installation holes are arranged ), the surface of the third connecting plate 17 is provided with a chute 18, the inner wall of the chute 18 is provided with an internal thread 19, a bolt 20 matching its internal thread 19 is installed in the chute 18, and a slide plate 21 is installed on the bolt 20 , the end of the sliding plate 21 away from the bolt 20 is connected to the first lower limb fixing frame 1; the second connecting mechanism includes a fourth connecting plate 22, and one end of the fou...

Embodiment 3

[0047] The difference between this embodiment and the second embodiment is that the internal thread provided on the inner wall of the chute 23 becomes an internal tooth, and the bolt 25 becomes a tooth block that cooperates with the internal tooth, that is, the first connecting mechanism includes a fifth connecting plate, and the second connecting plate One end of the fifth connecting plate is connected to the back plate, a chute is opened on the surface of the fifth connecting plate, internal teeth are arranged on the inner wall of the chute, and a tooth block matching the internal teeth is installed in the chute, and a tooth block is installed on the chute. The sliding piece, the end of the sliding piece away from the gear block is connected to the first lower limb fixing frame; the second connecting mechanism includes a sixth connecting plate, one end of the sixth connecting plate is connected to the back plate, and a slide groove is opened on the surface of the sixth connect...

Abstract

The invention discloses a fixation and traction brace for a femoral shaft fracture of an infant. The fixation and traction brace comprises a back plate, a lock catch structure is arranged on the back plate, one side of the lower portion of the back plate is connected with a first lower limb fixing frame through a first connecting mechanism, and the other side of the lower portion of the back plate is connected with a second lower limb fixing frame through a second connecting mechanism. The brace is compact in structure and can effectively perform the traction function on the femoral shaft fracture of the infant.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an infant femoral shaft fracture fixation traction brace. Background technique [0002] At present, femur fractures in infants rank second among infant fractures, and are common fractures in infants. Based on the special physiological characteristics of infants: strong healing ability and shaping ability, the treatment is different from that of ordinary children. Too much emphasis needs to be placed on anatomical reduction. The usual treatment method is double lower extremity skin traction. The double lower extremity skin traction method is bedridden for a long time, which is easy to cause crush, difficult nursing, unsatisfactory short-term curative effect, and pain for children and parents. Contents of the invention [0003] The object of the present invention is to provide a fixed traction brace for femoral shaft fractures in infants, which has a good traction effect for trac...
