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

Embodiment Construction

[0065] The present invention will be further described below in conjunction with embodiment.

[0066] like Figure 1-4 As shown, an adaptive skin stretching system according to the present application is characterized in that: comprising,

[0067] at least one pull force indicator,

[0068] The pulling force display part includes a flexible inner cylinder 1,

[0069] A flexible outer cylinder 2 socketed outside the flexible inner cylinder;

[0070] Slidable fit between flexible inner cylinder and flexible outer cylinder;

[0071] Both the inner and outer cylinders have end caps 3, and the inner parts of the two end caps are connected with springs 4;

[0072] Scales are drawn on the outside of the flexible inner cylinder or on the flexible outer cylinder to show the sliding distance when they slide relative to each other;

[0073] When the spring is at the initial length, the displayed scale is scale 0;

[0074] There are connecting parts 5 on the outer sides of the two e...

Abstract

The invention provides a self-adaptive skin traction system. The self-adaptive skin traction system is characterized by comprising at least one traction force display part, at least one tension adjusting part and a traction needle, wherein each traction force display part comprises a flexible inner cylinder and a flexible outer cylinder connected to the outer portion of the flexible inner cylinderin a sleeving mode; the flexible inner cylinder is in sliding fit with the flexible outer cylinder; the inner cylinder and the outer cylinder are provided with end covers, and springs are connected into the two end covers; scales are drawn outside the flexible inner cylinder or on the flexible outer cylinder, so that the sliding distance can be displayed when the flexible inner cylinder and the flexible outer cylinder slide relatively; when the spring is in the initial length, the displayed scale is a scale point 0; connecting parts are arranged on the outer sides of the two end covers; the at least one tension adjusting part is connected with the traction force display part; and the traction needle penetrates into the pulled skin, and a bridge-shaped arched hanging part connected with the traction force display part or the tension adjusting part is arranged on the needle.

Description

technical field [0001] The application relates to a medical device, in particular to an adaptive skin stretching 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 p...
