Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical treatment, in particular to a multifunctional traction bed for children with lower limb fractures. Background Art
[0002] Traction is a commonly used treatment method in orthopedics. It is a treatment method that uses traction and counter-traction to act on the fracture site to achieve reduction or maintain reduction and fixation. Bone traction is to insert a stainless steel needle into the hard part of the bone and directly pull the bone through the traction steel needle. Traction therapy is a commonly used treatment method for lower limb fractures in children. Its purpose is to reduce and maintain stability of fracture dislocation. Traction therapy not only avoids the trauma and pain caused by surgical treatment, but also caters to the advantage of fast healing of fractures in young children. The traction process can not only relieve muscle spasms and improve venous return, but also achieve the effect of eliminating limb swelling due to the braking and elevation of the affected limb, and the traction angle can be accurately adjusted by adjusting the height of the upper and lower crossbars and the length and width of the Thomas frame. Most fractures in children under 3 years old are treated conservatively, that is, suspension traction of the affected limb. At present, there are movable lower limb bone traction beds suitable for children in China, while traction beds specially used for lower limb fractures of infants and young children can only perform vertical suspension skin traction of both lower limbs. This traction method is not suitable for slightly older children, which limits the scope of application of traction beds. Utility Model Content
[0003] In order to solve the problems in the background technology, the utility model provides a multifunctional traction bed for children's lower limb fractures.
[0004] The specific technical solution of the utility model is as follows:

A first tightening assembly 05 is arranged on the traction rod 03, and the first tightening assembly 05 can control the disassembly and assembly of the traction rod 03. The installation area of the traction rod 03 is close to one end of the traction rod 03, and the end is called the proximal end. The other end of the traction rod 03 is farther from the proximal end of the main traction frame 02, and is called the distal end. The distal end can be installed in two directions, namely, toward the head of the bed or the end of the bed. A thigh support 06 is arranged between the middle part of the main bed body 01 and the traction rod 03, and the thigh support 06 is arranged to be inclined from front to back and from bottom to top. A calf support 07 is installed in the middle part of the thigh support 06, and one end of the calf support 07 is hinged to the thigh support 06, and the other end extends toward the end of the bed. The middle part of the calf support 07 is placed on the main traction frame 02. The thigh support 06 and the calf support 07 have formed the so-called Thomas-type frame.
[0027] In this embodiment, the traction rod 03 can be installed on the main traction frame 02 in two different directions. When the distal end of the traction rod 03 is installed toward the head of the bed, the two traction wheels 04 of the traction rod 03 are close to the head of the bed, and the traction rope and gravity hammer can be used for pediatric skin traction suspension treatment. At this time, the Thomas frame is not needed and can be removed. When the distal end of the traction rod 03 is installed toward the foot of the bed, the Thomas frame, traction rope and gravity hammer can be used for bone traction treatment. At this time, the patient lies flat on the main bed body 01, the thigh is placed upward along the thigh support 06, the calf is bent and placed on the calf support 07, one end of the traction rope is hung on the buckle of the traction bow to pull the lower limbs, and the other end is passed around the two traction wheels 04, and a heavy object is hung at the end.
