Description

Orthopedic surgery leg adjustable distraction support

technical field

The invention belongs to the technical field of medical care equipment, and in particular relates to an adjustable leg traction bracket for orthopedic surgery.

Background technique

At present, in surgical operations, especially for patients undergoing orthopedic lower limb surgery, in order to ensure the quality of the operation, it is generally necessary to fix the lower limbs of the patient before the operation, so as to avoid unnecessary damage during the operation and reduce the pain of the patient. . The existing practice is generally to support the patient's legs by medical staff, or use sterile towels to elevate the patient's lower limbs, so as to facilitate the doctor's operation. This method not only increases the burden on the medical staff, but also , the position of the patient's legs is not easy to fix, which affects the fixation of the patient's fracture site during the doctor's operation, which ultimately affects the quality of the operation and increases the pain of the patient. On the other hand, with the development of population aging, hip fractures of the elderly are increasing year by year. Traditionally, for the postoperative care of patients with hip fractures, anti-rotation shoes are generally used to maintain them in a neutral position. The method cannot adjust the height arbitrarily, and it cannot meet the needs of patients to raise their limbs in the early postoperative period, which increases the difficulty of nursing the affected limbs.

The invention with publication number CN 2033670U provides a multifunctional orthopedic lower limb support. The height adjustment of this support is poor, very rigid, the angle cannot be adjusted, the comfort is not increased, and the operation is troublesome.
