Description
Technical Field
The invention relates to the technical field of skin tension measurement, in particular to an adjustable skin tension measuring device.
Background
The amount of skin tension at the wound site is directly related to whether the wound can be directly closed, what method and materials should be used for wound closure, and the extent of scar hyperplasia after wound healing. The simple and adjustable wound skin tension tester is manufactured, and has important guiding significance for clinical application and scientific research.
At present, no special measuring instrument for measuring wound skin tension exists clinically. The existing skin stretching devices which are clinically used are skin stretching devices aiming at overlarge wound tension and can not be directly pulled in for suturing. The traditional skin stretching device is characterized in that a Kirschner wire is respectively and parallelly penetrated at two sides of a skin wound, and then the Kirschner wire at two sides of the wound is pulled by mechanical force to close the wound. The device aims to pull the skin to close the wound, but the tension of the skin at the wound cannot be measured. It is known that there is a limit to the tension that skin can withstand, and excessive tension can cause skin tearing and the risk of ischemic necrosis at the skin margin. Thus, there is a need for an adjustable wound skin tension measuring instrument for measuring the skin tension at a wound site.
Improvements have been made over conventional skin retractors. Chinese patent CN201711065999.8 describes a tension-adjustable skin retractor Zhang Wenge. The device comprises a force measuring structure and two sets of skin stretching structures distributed on two sides of the force measuring structure, wherein the force measuring structure adopts a spring force measuring meter. Although the device can measure the tension of the skin at the wound site, it is still a skin stretching device for stretching the skin to close the wound, rather than being specifically used to measure the wound skin tension. In addition, the measuring device adopts a spring dynamometer, is relatively heavy, and has inaccurate force measurement, and particularly for the part with small wound skin tension, the tension of the wound skin cannot be accurately measured.
It is therefore considered that a medical device which is mainly used for accurately measuring skin tension at a wound site and which can measure skin tension of different sizes and which can assist skin stretching when necessary, is a background of the present invention.

Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
As shown in fig. 1:
the skin tension tester comprises a force measuring device and a set of skin stretching devices which can be fixed on two sides of wound skin. The skin stretching device comprises two fixing feet 1 which are used for being fixed on the skin at two sides of a wound, a connecting rod 2 which is connected with the two fixing feet 1, a pushing piece 3 which pushes the two fixing feet 1 to slide on the connecting rod 2, and a locking structure 4 on the pushing piece 3. The pushing member 3 is in a thread shape, when the pushing member 3 is rotated, the two fixing legs 1 can approach along the thread direction, so that the wound is closed, and after the wound is closed, the locking structure 4 is used for locking.
Further, two fixing feet 1 which can be used for fixing on the skin at two sides of the wound are composed of a needle frame and 2 metal sheets which are connected above the needle frame and are arranged side by side, the direction of the metal sheets is perpendicular to that of the needle frame, small holes are formed in the metal sheets, and the interval between the 2 metal sheets is 1cm. The metal sheet can be well adhered to the skin surface and fixed on the skin through adhesive tape adhesion or stitching.
Further, the two needle frames are connected into a whole through two connecting rods 2. The connecting rod2 is a metal rod with the diameter of about 2mm, one end of the connecting rod is fixed with the needle frame, and the other end of the connecting rod penetrates through the needle frame, so that the needle frame can freely move on the connecting rod without resistance. The pushing piece 3 is arranged between the two connecting rods 2, the pushing piece 3 is a threaded metal rod, the needle frame penetrates through the centers of the two connecting rods 2, and the locking structure 4 at the tail end is rotated to push the fixed foot at one side to move towards the other direction until the skins at the two sides are closed.
Further, the force measuring device is a pressure sensing force measuring device. A spring 5 is mounted at the other end of the pusher 3 (opposite to the locking structure), and a pressure sensor 6 is mounted at the tail end of the spring 5. The other end of the pressure sensor 6 is connected to a display 7. Under the condition that the skin wound is not subjected to any external force and naturally opened, the spring on one side of the pressure sensor 6 is completely loosened, and the pressure sensor 6 has no pressure, and the reading value is zero. When the locking structure 4 at the tail end of the pushing piece 3 is rotated, the wound is closed under the action of tension, and meanwhile, the spring 5 at the tail end of the pushing piece 3 is pressed to press the pressure sensor 6, so that the pressure is sensed, and finally, the pressure sensor 6 displays the pressure in a numerical mode, and indirectly reflects the skin tension of the wound.
The working principle of the invention is as follows:
When in use, the two fixing feet 1 are respectively fixed on two sides of a skin wound, and the metal sheets on the fixing feet 1 can be well attached to the skin surface and fixed on the skin through adhesive tape adhesion or suture. When the tension is particularly high, the wound can also be fixed on the wound by passing a Kirschner wire through the metal sheet on the fixing foot 1 and then through the skin on both sides of the wound.
After the two fixing feet 1 are tightly fixed with the skin at the two sides of the wound, the locking structure 4 on the pushing piece 3 is adjusted, so that the locking structure 4 is positioned at the initial position of zero tension of the wound. At this time, the wound is naturally opened without any external force, the two fixing feet 1 are positioned at two sides of the wound, and the locking structure 4 is abutted against the fixing feet 1. The other end of the spring 5 is in a fully relaxed state and the pressure sensor 6 does not receive any pressure and reads zero.
When the tension is needed to be measured, the locking structure 4 on the pushing rod 3 is rotated to fold the skin at two sides of the wound under the pushing force, the spring 5 at the other end of the rod of the pushing member 3 is infected with pressure and is compressed and deformed, and the baroreceptors 6 at the tail ends of the spring 5 are specifically displayed as the pressure values sensed by the baroreceptors. When the skins of the wounds on the two sides are completely closed, the screwing of the locking structure 4 is stopped, and the pressure sensed by the other pressure sensing device of the pushing rod 3 is the tension of the skin wounds.
