Description

Technical Field

[0001] The utility model relates to the technical field of medical surgery, in particular to a limb lifting mechanism for surgery. Background Art

[0002] Surgery refers to the treatment of excision, suturing and other treatments performed by doctors on the patient's body with medical instruments. It uses knives, scissors, needles and other instruments to perform operations on local parts of the human body to maintain the patient's health. Early surgeries were limited to simple manual methods to cut, cut and sew on the body surface, such as abscess drainage, tumor resection, trauma suture, etc. Some patients need to lift their limbs during the operation to facilitate the smooth progress of the operation. Since patients need to raise their limbs and lie in a supine position during the operation, especially elderly patients and slightly fat patients, when the limbs are lifted for wound cleaning during the operation, the patients cannot support themselves and need to be lifted manually by medical staff. Medical staff cannot hold on to the manual lifting for too long, which easily causes fatigue to medical staff. The stability of the existing support for lifting limbs is not good, causing the limbs to shake, affecting the normal progress of the operation.

[0003] Existing equipment cannot conveniently adjust the lifting support position when performing limb lifting operations, resulting in reduced stability of the supported limb. In addition, existing equipment is prone to loosening or detachment when fixing limbs, which can easily cause the limb to fall and cause injury during lifting support, affecting the stability and practicality of the equipment for lifting limbs.
