Gravity traction device for lower limb traction frame

Abstract

The invention relates to a gravity traction device for a lower limb traction frame, and belongs to the technical field of medical instruments. The device comprises a gravity machine body, wherein thegravity machine body is composed of a mounting cylinder, a balancing weight, an electronic scale, an upper positioning plate, a weighing spring and a lower positioning plate; the mounting cylinder isinternally slidingly provided with the balancing weight made from metal, the inner wall of the portion, located under the balancing weight, of the mounting cylinder is provided with an annular mounting boss, the portion, located under the mounting boss, of the mounting cylinder is internally provided with the electronic scale, the top of the balancing weight is provided with a flying ring, and thebottom of the balancing weight is provided with a gravity rod. The gravity traction device for the lower limb traction frame has the advantages that the structure is simple, the practicability is good, and the problems are solved that the strength of the tractive force of an existing traction supporting device cannot be presented visually, and the increase and decrease of the weight of a gravitysource cannot be adjusted accurately; and the device has the characteristics of simple structure and good practicability, and is especially suitable for the mounting use of the lower limb traction frames.

Description

technical field [0001] The invention relates to a gravity traction device for a lower limb traction frame, which belongs to the technical field of medical instruments. Background technique [0002] Traction plays an important role in the treatment of lower extremity fractures. It is suitable for conservative treatment of lower extremity fractures, or to maintain the length and axis of the lower extremity before surgical treatment. For example, patients with arthrosis usually need to conduct traction on their joints during surgery to increase the bone-joint space to facilitate surgery. The way of traction is: when the patient undergoes foot and ankle surgery, after the ankle joint is fixed with an ankle sleeve, the ankle sleeve is pulled by the traction rope to achieve the purpose of pulling the joint gap. The traction rope needs a support device as a support during traction. At present, the existing The traction support device comprises bracket, bracket end welding and vert...
