Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fixation bracket for an affected limb in a femoral intramedullary nail fixation procedure. Background Art

[0002] Femoral fracture surgery currently mostly uses closed reduction and internal fixation to treat. The specific surgical steps are to fix the patient on a traction bed and apply longitudinal traction to the affected limb. This can reduce the fracture.

[0003] In the existing femoral closed reduction and internal fixation (traction bed) surgery, in order to prevent the affected upper limb from affecting the surgical operation, the affected upper limb needs to be fixed with a bandage on the anesthesia frame before the surgery is performed.

[0004] However, using a bandage to fix the affected upper limb to the anesthesia frame can easily cause local skin pressure injury. At the same time, when fixing the affected upper limb, it is necessary to wrap the affected upper limb around the anesthesia frame with a circle of bandages, which takes a long time to fix and affects the operation time.

[0005] Therefore, it is necessary to provide a fixation bracket for the affected limb of femoral intramedullary nail fixation to solve the problems raised in the above background technology. Utility Model Content
