Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a modified knee compression tool for use after knee surgery. Background Technology

[0002] The knee joint is an important weight-bearing joint in the lower limbs, and its structure and function are among the most complex of all human joints. Knee replacement surgery can relieve knee pain, improve knee function, correct knee deformities, and achieve long-term stability.

[0003] Patients often maintain a flexed knee position for extended periods before surgery to alleviate knee pain. Although doctors make thorough corrections during the procedure, most patients still retain some degree of flexion deformity after surgery, affecting their walking function and daily life. This can even cause abnormal stress stimulation to the knee joint prosthesis, shortening its lifespan.

[0004] Currently, sandbags are used clinically to correct knee flexion deformities through continuous physical compression, which helps patients recover their extension function after surgery. Traditional sandbags are mostly rectangular cloth bags filled with 2 kg of fine sand evenly.

[0005] However, due to the limitations of the knee structure, when traditional sandbags are placed on the knee joint, only one point of the sandbag contacts the top of the patient's patella. This makes it very easy for the sandbag to slip off the knee joint, ultimately failing to guarantee the effectiveness of the sandbag treatment. Furthermore, traditional sandbags directly compress the incision in the middle of the patient's knee joint, causing wound pain and affecting the patient's compliance with using the sandbag. In some cases, the direct pressure of the sandbag on the wound may even lead to poor wound healing. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of traditional sandbags in the prior art, which are easy to fall off and directly compress the midline incision of the patient's knee joint, thus affecting wound healing, and to provide an improved knee compression tool for use after knee joint surgery.

[0074] In this technical solution, two sandbag bodies 3 can be placed on the weight-bearing bags 2 on both sides. The two sandbag bodies 3 are located on the left and right sides of the knee joint. The equal sandbag bodies 3 on both sides can make the knee joint bear the force evenly, which can increase the stability of the pressure bag body and prevent the pressure bag body from slipping and affecting the effect of knee pressure treatment. At the same time, when wearing it, the connecting strap 1 contacts the incision in the middle of the knee joint and places the sandbag bodies 3 on both sides, thereby transferring the weight, reducing wound tension, relieving pain, and improving patient comfort.

[0075] Research and clinical trials have shown that the ice pack body 5 uses a 10% saline ice pack and the sandbag body 3 weighs 4kg. Using both of these to apply pressure and cold compress to the patient's knee joint is a suitable method. The knee pressure times are 9 o'clock, 12 o'clock, 3 o'clock, and 6 o'clock, four times a day, and each time the knee pressure time is 30 minutes.

[0076] When applying knee pressure, the patient should be in a lying position with their feet elevated by 15cm and suspended in the air. This position provides a better knee-pressing effect when using the knee-pressing tool.
