Description

Wrist movement evaluation device

Technical Field

The utility model belongs to medical equipment, in particular to a wrist movement evaluation device.

Background

The free forearm skin flap is one of the skin flaps commonly used for head and neck soft tissue defect repair and reconstruction, is a skin flap taking a radial artery and a cephalic vein as axial blood vessels, and is commonly used for the repair and reconstruction of small and medium-sized soft tissue defects at present. Traditional forearm skin flap confession district need be followed the abdomen or thigh and is surely got full thickness skin or the free skin grafting of sword thick skin piece because of getting unable direct drawing together of sewing up behind the skin flap, the scar that forms behind the free skin grafting and the shrink of the skin piece of implanting etc. cause the wrist motion to be restricted often, it is mainly that wrist adduction and the wrist abduction degree of wrist obviously dwindle before than to be used, even still can't reach wrist adduction and wrist abduction degree before the art after training through long-time wrist motion function, influence patient's hand function and quality of life. The back has designed "V" shape forearm skin flap, cuts and gets behind the V shape forearm skin flap forearm art wound and can close directly through drawing close the suture, does not use free skin grafting, and the scar of formation is less, has reduced the influence of postoperative scar to wrist motion.

However, a quantitative measurement device for wrist movement is absent at present, the amplitude of wrist movement cannot be accurately measured, the degree of wrist movement before and after an operation can be evaluated only through visual inspection and individual feeling of a patient, accuracy is absent, and data cannot be counted.
