Electric scab excision machine used for deep second degree burn

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...

Problems solved by technology

[0003] Chinese patent 201220138558.2 has reported a kind of electric variable speed burn scab device, and it is to utilize electric motor to drive scab cover to rotate and remove scab on wounded person's burn, this patent is electric drive, can reduce the physical exertion to clinician, but this patent If the necrotic tissue removed by grinding is not removed in time, splashes and residues will be generated, which will affect the judgment of the depth of the wound, and it has serious defects in clinical application:

[0004] Chinese patent 02256217.6 has reported a kind of medical scab grinding device for burns, which utilizes a motor to drive a rotating knife connected to it to rotate and remove scab tissue. This patent grinder does not have a tool changing function. The grinding hole will be blocked by the removed necrotic skin, affecting the grinding function, and one kind of grinder only corresponds to one kind of tool, which is not conducive to recycling

It cleans the wound surface by manually operating the scab head equipped with the scab cover. This patent requires manual scab operation, which requires high physical strength for the clinician. When dealing with large burn wounds, the operation time will be significantly increased, and the Difficulty of surgery and risks of anesthesia
