Abstract

The invention discloses a skin expander for large wound healing and a use method, and relates to the technical field of medical auxiliary instruments. The skin expander for large wound healing comprises hook claws and adjusting boxes, the multiple adjusting boxes are arranged in an array mode in the horizontal direction, the hook claws are symmetrically arranged on the lower portions of the two sides of each adjusting box, the tops of the hook claws are fixedly connected with a rotating frame, and the rotating frame is rotationally connected with the lower end of an L-shaped connecting rod; the upper end of the L-shaped connecting rod is fixedly arranged on the bottom face of the connecting plate, an adjusting rod is integrally formed on one end face of the connecting plate, and a rack is arranged on one side face of the adjusting rod. The adjusting box is hollow with two open ends, and the adjusting rods at the two ends of the adjusting box are inserted into the same adjusting box in a sliding mode. The device can effectively avoid the pain and discomfort of a patient caused by the pulling friction between a binding line and the skin and the relative sliding between the claw and the skin, and meanwhile, the device can be adjusted according to the lines of a wound, and is good in adaptability.

Description

technical field [0001] The invention belongs to the technical field of medical aids, and in particular relates to a skin expander for healing large wounds and a method of use.
