Self-adapting skin traction system and skin traction method

Abstract

The application provides a self-adapting skin traction system. The self-adapting skin traction system is characterized by comprising one or more traction force displaying parts, one or more pulling force adjusting parts each of which is connected with the corresponding traction force displaying part, and a traction needle, wherein each traction force displaying part comprises a flexible inner cylinder and a flexible outer cylinder connected to the flexible inner cylinder in a sleeving manner; each flexible inner cylinder can be in sliding cooperation with the corresponding flexible outer cylinder; end covers are arranged on each inner cylinder and each outer cylinder; a spring is connected to the inner parts of the two end covers; graduation is drawn outside each flexible inner cylinder oreach flexible outer cylinder, so that when the flexible inner cylinder and the flexible outer cylinder are in relative sliding, the sliding distance can be displayed; when the spring is under an initial length, the displayed graduation is the zero point of the graduation; a connection part is arranged on the outer sides of every two end covers; the traction needle rips into traction skin; the needle body is hollow; a hole which enables the hollow part and outside to be in communication is formed in one side of the needle body; a thread penetrates into the hole, and at least a part of the thread is fixedly bound to the needle body; and after the traction needle rips the skin, the thread is attached to the traction force displaying parts or the pulling force adjusting parts. The applicationfurther provides a skin traction method.

Description

technical field [0001] The application relates to a medical device, in particular to an adaptive skin Dara system in the process of skin healing and growth on a large wound surface. Background technique [0002] After a patient is injured in a serious accident, the skin will shrink from the wound. After wound surgery, the skin edge at the wound needs to be pulled slowly and continuously to make it proliferate gradually, so as to re-cover the wound and restore recovery. Purpose. The pulling process lasts for several weeks, and during this process, the magnitude and direction of the pulling force must be precisely controlled at all times, otherwise it may cause uneven skin growth or failure to break. [0003] There have been some skin retractors, such as Citation 1: CN104826219A, its principle is to pierce the puncture needle 34 into the skin at the edge of the wound, and then use three groups of screw mechanisms to slowly narrow the distance of the puncture needle to pull th...

Problems solved by technology

[0008] Citations 3 and 4 can be referred to as the second type of retractors, which are characterized by the transmission of pulling force through pull wires, but there is a new problem in this type of solution, that is, the pull wires will press the deep muscle layer of the wound , impedes blood flow, making growth poor

Because human limbs are curved everywhere, for large wounds, the tensioned pull wires press down on the curved muscles for a long time, which may cause new injuries
