An adjustable lower limb bone traction device without weights

Abstract

The invention discloses an adjustable lower limb bone traction device without weights, which includes a three-dimensional support, a traction assembly and an adjustment assembly arranged on the three-dimensional support; the traction assembly includes an upper pulley, a lower pulley, a traction rope and a spring; The adjustment assembly includes an upper pulley adjustment locking device and a lower pulley adjustment locking device. The upper pulley adjustment locking device can be adjusted and installed on the three-dimensional support and is connected with the upper pulley through a side fixing rod. The lower pulley adjustment locking device includes an auxiliary adjustment locking device and the twist-stop integrated device, the auxiliary adjustment locking device and the twist-stop integrated device are respectively connected to the lower pulley through the fixed rod, and the auxiliary adjustment lock device can be adjusted and installed on the horizontal sliding rod, and the twist-stop integrated device uses a knob The way of twisting and walking is installed on the top toothed track. The invention is convenient for adjustment, can effectively prevent the occurrence of foot varus, and can better meet the needs of clinical treatment.

Description

technical field [0001] The invention relates to a weightless adjustable lower limb bone traction device, which belongs to the field of medical instruments. Background technique [0002] Bone traction is a way to directly pull bones through circular needles, so as to effectively reduce and fix fractures and dislocations. It is often used for preoperative reduction of unstable fractures and plaster fixation difficulties. Among them, lower extremity traction is currently the most commonly used method of bone traction. At present, the implementation of lower extremity skeletal traction mainly relies on Brown's skeletal traction frame. Existing Brown type bone traction frame is made up of main body stainless steel or metal iron support frame, traction bow, gauze bandage or cloth belt, bedside fixture, pulley, traction rope, weight hook, weight etc. The main structure of the Brown-type skeletal traction frame is welded by iron or stainless steel. This structure has the advantage...
