Self-adaptive skin traction system and skin traction method

Abstract

The invention provides a self-adaptive skin traction system. The system is characterized by comprising at least one traction force display part, at least one tension adjusting part and a traction needle, wherein the traction force display part comprises a flexible inner cylinder and a flexible outer cylinder which is connected outside the flexible inner cylinder in a sleeving manner; the flexibleinner cylinder and the flexible outer cylinder are in sliding fit; the inner cylinder and the outer cylinder are provided with end covers; springs are connected inside the two end covers; scales are drawn outside the flexible inner cylinder or on the flexible outer cylinder, and the sliding distance can be displayed when the flexible inner cylinder and the flexible outer cylinder slide relatively;when the springs are at the initial length, the displayed scale is the zero point of the scale; connecting parts are arranged on the outer sides of the two end covers; the tension adjusting part is connected with the traction force display part; the traction needle penetrates into the skin to be pulled; a through groove is formed in the needle body; anti-skid teeth are arranged on the groove wall; a line penetrates through the through groove; at least one part of the line is fixedly bound with the needle body; and after the traction needle penetrates into the skin, the line is hooked with thetraction force display part or the tension adjusting part.

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
