Abstract

The invention belongs to the field of medical instruments, and discloses a knee joint stretching assisting bag which comprises an outer sleeve and inner sleeves. Cloth bags are arranged on the two sides of the outer sleeve respectively; two inner sleeves are arranged in the cloth bags on the left side and the right side of the outer sleeve respectively; soft suede cloth with the appropriate width on the upper portion and the lower portion of the outer sleeve is tightly attached to the skin; sticking buckles are arranged at openings of the cloth bags on the two sides of the outer sleeve; sticking buckles are arranged at openings of the inner sleeves; and 1.5 kg of 6.4 mm stainless steel balls are respectively arranged in each inner sleeve. The knee joint stretching assisting bag is proper in size and weight, convenient and comfortable to use, soft and comfortable in cloth of the outer sleeve, capable of being clung to the two sides of the knee joint, difficult to slip off and easy and convenient to operate; an opening is designed in the middle to avoid a surgical incision and avoid the compression pain and influence on blood flow of the incision; the stainless steel balls are placed in the inner sleeves, the hardness is moderate, the density is large, components are pure, the surface is smooth, rustless, clean and non-permeable, and in a case of ensuring the weight, the knee joint stretching assisting bag has the advantages of small size, attractiveness and neatness.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a knee joint extension bag. Background technique [0002] At present, with the aging of China, there are more and more patients with knee osteoarthritis. Most of these knee osteoarthritis patients present with flexion and varus deformity. Total knee arthroplasty (TKA) ) has become an important treatment method for patients with end-stage joint diseases such as osteoarthritis and rheumatoid arthritis. The purpose of TKA surgery is to relieve joint pain, correct joint deformity, and obviously restore joint function ,improve the quality of life. During the whole treatment process of the patient, in order to obtain the expected effect, in addition to the surgical operation, effective postoperative rehabilitation training is a very important link; , there will still be residual flexion contracture, and the knee joint cannot be fully straightened. Therefore, in the early po...

Problems solved by technology

During the whole treatment process of the patient, in order to obtain the expected effect, in addition to the surgical operation, effective postoperative rehabilitation training is a very important link; , there will still be residual flexion contracture, and the knee joint cannot be fully straightened. Therefore, in the early postoperative rehabilitation training, there are active extension training and passive extension training. However, due to postoperative pain, most patients cannot perform Active straightening training, so passive straightening training is required, that is, to apply some external force to the knee joint area to promote knee joint straightening; currently there is no clinical standard equipment for such patients, and most of them use plastic bags or simple sandbags made by women's stockings , rice bag to carry out compression knee joint straightening exercise, this method has some disadvantages:

[0003] 1. The fixation is not firm, it is easy to slip off, and it is difficult to stick to the knee;

[0004] 2. Impurities in sandbags are easy to leak out through the bag and affect the wound;

[0005] 3. Traditional rice bags and sandbags are inconvenient to use due to the low density of the contents, which are 6-8 catties in size;

[0006] 4. Directly compressing the wound causes pain and poor comfort. At the same time, compressing the incision affects the blood supply of the skin around the incision and affects the healing of the incision.
