Abstract

The invention discloses an electric scab excision machine used for deep second degree burn. The electric scab excision machine comprises a machine body; a handle meeting the human engineering is arranged at the back half portion of the machine body; a motor is arranged in the machine body; a main shaft of the motor is connected with a hollow first transmission shaft; the first transmission shaft is connected with a second transmission shaft; the second transmission shaft penetrates the front end of the machine body to enter a sleeve connected with the front end of the machine body; the front end of the second transmission shaft extends out of the sleeve to be connected with a spring jacket type cutter handle; and a cutter is installed on the spring jacket type cutter handle. The electric scab excision machine is connected with an alternating current power source through a transformer; and a switch button is turned on, and the motor in the handle is started to drive the first transmission shaft, the second transmission shaft, a third transmission shaft, the cutter and an impeller to rotate. After the cutter is in contact with the skin, bouncing can be generated in the axial direction and the radial direction, and injuries, caused by overcutting, to the normal skin tissues are avoided. Generated skin cuttings are filtered and absorbed through a dust exhaust apparatus, and the cuttings are prevented from being splashed everywhere.

Description

technical field [0001] The invention relates to an electric scab-shaving machine for deep second-degree burns. Background technique [0002] At present, deep second-degree burns have always been the focus and difficulty of research and treatment in the field of burn surgery. More and more attention has been paid to the application of abrasive escharotherapy in deep second-degree burn wounds. Scab, in a broad sense, is equivalent to dermabrasion, which refers to the use of instruments to remove part of the skin tissue through shear force to form a wound, mobilize the re-epithelialization of wound margins and underlying healthy tissues, and has achieved the effect of promoting wound healing or improving skin appearance. therapeutic purposes. In a narrow sense, abrasive scab refers to rubbing and rubbing on the wound surface with tools with rough surface to remove necrotic tissue, and the degree of pinpoint bleeding or tissue redness reaches the healthy layer. For mixed degr...
