Description

Traction bow for contracture deformity of fingers and toes

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to hand and foot finger (toe) contracture deformity traction bow.

Background

Scar hyperplasia and contracture of fingers (toes) of hands and feet caused by deep burn are common problems in the department of burn orthopedics. The traditional treatment method comprises scar loosening, local skin flap transfer and skin grafting, in order to completely straighten the fingers (toes) of the hands and avoid the recurrence of postoperative early contracture deformity, intramedullary kirschner wire fixation is conventionally carried out in the operation, and the fingers are fixed at the straightening position for 2-4 weeks; and (or) adopting an external fixing brace for auxiliary fixation after operation. Scar excision release and intramedullary needle fixation can temporarily and completely release adhesion, but new scar adhesion contracture can be generated again in the process of tissue repair after operation, tendon adhesion can even occur, and the scar contracture can relapse even worse. The use of the external fixation brace has the problems of unobvious effect, easy generation of pressure sores and blisters, poor patient adaptability and the like. Both approaches have difficulty achieving the desired results.

Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings 1-2.

With reference to fig. 1 and 2, the traction bow with contracture of hand, foot and toe of this embodiment, as shown in fig. 1, including having elastic traction bow 1 the bending forms finger (toe) fixed area 2, tension area 3 and palm (metatarsal) fixed area 4 on the traction bow 1, tension area 3 is "U" shape, finger (toe) fixed area 2 and palm (metatarsal) fixed area 4 are located tension area 3 both ends respectively, finger (toe) fixed area 2 includes that section 21 and finger (metatarsal) anticreep section 22 are put into to finger (toe) bone, finger (toe) bone anticreep section 22 sets up respectively at both ends that section 21 was put into to finger (toe) bone, section 41 and section 42 are put into to anti-disengaging (metatarsal) bone section 4 including palm (metatarsal) bone, palm (metatarsal) bone anticreep section 42 puts into section 41 both ends of section respectively in palm (metatarsal) bone, tension area 3 is used for providing the same direction with the extension of the straight joint for finger (metatarsal) fixed area 2 and 4)

fixed area

2, 4, and palm (metatarsal extension direction Force; as shown in fig. 2, which is a schematic view of the traction bow of contracture deformity of fingers and toes when not in use, the anti-drop section 22 for finger (toe) bone and the anti-drop section 42 for palm (metatarsal) bone at the outer ends of the finger (toe) bone insertion section 21 and the palm (metatarsal) bone insertion section 41 are not formed yet, and the tension area 3 is in a U shape with a larger opening.

The application mode of the traction bow for contracture deformity of fingers (toes) of the hand is as follows: firstly, at the far end of the contracture scar, for example, at the end of a finger, a kirschner wire is vertically inserted into the finger bone to penetrate the finger bone, the kirschner wire is withdrawn, and the near end of the contracture scar is treated in the same way, such as the palm, which is also required to penetrate the metacarpal bone, the finger (toe) bone insertion section 21 and the metacarpal (metatarsal) bone insertion section 41 are respectively inserted from the needle hole, after a certain distance is left, the ends of the finger (toe) bone insertion section 21 and the metacarpal (metatarsal) bone insertion section 41 are respectively bent to form the finger (toe) bone anti-falling section 22 and the metacarpal (metatarsal) bone anti-falling section 42 at the outer ends.
