Problems solved by technology

But about a method that can simulate traditional Chinese medicine "traction", "rotational reset", "fixed-point reset" and other methods, through mechanical design and intelligent control to achieve five treatments: horizontal traction, flexion and extension traction, lateral flexion traction, rotation traction and waist positioning push At the same time, there is no relevant report on a kind of medical hydraulic traction equipment and its hydraulic control system that uses the combination of intelligent control system and mechanical transmission system to realize fast traction and slow traction, thereby improving the effect of traction treatment.

Abstract

The invention relates to medical hydraulic traction equipment and a hydraulic control system thereof. The hydraulic traction equipment comprises an equipment body, an upper body plate, a lower body plate, a first connecting shaft and a second connecting shaft; a horizontal traction hydraulic cylinder, a waist jacking part hydraulic cylinder and an angle forming part hydraulic cylinder are arrangedin the equipment body; the first connecting shaft is arranged behind the equipment body, and a plurality of lifting devices are arranged on the first connecting shaft; the second connecting shaft isarranged below the first connecting shaft, and a supporting plate is hinged to the second connecting shaft; a swing angle part hydraulic cylinder and a rotating part hydraulic cylinder are arranged onthe supporting plate; and the angle forming part hydraulic cylinder is arranged at the bottom of the equipment body. The equipment has the advantages that: traditional Chinese medicine traction, rotary reset, fixed-point reset and other manipulations can be simulated, horizontal traction, flexion and extension traction, lateral flexion traction, rotary traction and waist positioning pushing jacking treatment modes are achieved through mechanical design and intelligent control, and therefore the traction treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical traction therapy, in particular to a medical hydraulic traction device and a hydraulic control system thereof. Background technique [0002] Low back pain is a common clinical disease. According to statistics, more than 40% of people over the age of 40 in my country suffer from various lumbar diseases. Lumbar traction is a safe and effective treatment. In ancient Chinese medical literature, there are also records of traction treatment such as "guiding and pressing the stilts", "shaking the muscles and bones, moving the joints" and "guiding and pulling the waist, moving the joints", which is the embryonic form of the development of modern traction therapy. The development of modern medicine, especially the development of spinal anatomy, physiology, biomechanics and the renewal of traction equipment, has laid a theoretical foundation for the development and clinical application of modern traction t...
