Supporting tool capable of resisting lower limb retraction

Abstract

The invention relates to a support capable of resisting lower limb retraction, which is characterized in that the end parts of a leg support part are respectively fixed together with two ends of a rotating device through skeleton connecting bolts, and a fixing belt is arranged outside the leg support part; the rotating device comprises a first base and a second base which are the same in structure, the first base and the second base are symmetrically, parallelly and alternately located between the two leg supporting pieces, shaft heads are installed in the first base and the second base in an interference mode to form movable structures of the shaft heads, and the two shaft heads are connected with the two ends of a rotating shaft through bearings; each shaft head is provided with a limiting device, positioning grooves are formed in the first base and the second base corresponding to the limiting devices, and the limiting devices and the positioning grooves are matched to form a limiting structure of the shaft heads. The device is simple in structure, scientific and reasonable in design, easy to produce and manufacture, easy to operate and suitable for patients with different heights, lower limb body types, lower limb activity ranges, muscle forces and operation conditions, the medical compliance and the treatment effect of the patients are obviously improved, and good social and economic benefits are achieved.

Description

technical field [0001] The invention relates to a medical device for joint surgery, in particular to an anti-lower extremity adduction support device. Background technique [0002] One of the most serious complications after hip replacement is the dislocation of the replaced joint. Because for a certain period of time after the operation, the patient needs to avoid the adduction of the lower limbs to prevent the occurrence of hip dislocation and local hematoma. At present, abduction pillows, also known as orthopedic pillows, trapezoidal pillows, positional cushions, etc., are routinely used to solve such problems. However, due to structural deficiencies, this type of soft pillow or cushion has many problems: 1. It only has a static fixation effect. For example, if the patient walks on the ground, or only moves a little on the bed, the position will shift and the fixation effect will be lost; 2. Many hip replacement surgery patients are elderly patients. Fixing the patient ...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the object of the present invention is to provide an anti-adduction brace of the lower limbs, which can effectively solve the problems of single function, fixed model and poor wearing effect of the existing anti-adduction devices of the lower limbs.
