Description

Adjustable skin tension meter

technical field

The utility model relates to the technical field of skin tension measurement, in particular to an adjustable skin tension measuring device.

Background technique

The size of the skin tension at the wound site is directly related to whether the wound can be closed directly, what method and material should be used for wound closure, and the degree of scarring after the wound heals. Making a simple and adjustable wound skin tension tester has important guiding significance for clinical application and scientific research.

At present, there is no specific instrument for measuring wound skin tension in clinical practice. At present, the clinical use of skin stretchers is that the tension of the wound is too large and cannot be directly sutured. The traditional skin stretcher is to insert a Kirschner wire in parallel on both sides of the skin wound, and then use mechanical force to stretch the Kirschner wires on both sides of the wound to make the wound close and close. The device is designed to pull the skin to close the wound, but cannot measure the tension of the skin at the wound. As we all know, there is a certain limit to the tensile force that the skin can withstand. Excessive tensile force will cause the skin to tear and the risk of ischemic necrosis of the skin edge. Therefore, we need an adjustable wound skin tension measuring instrument to measure the skin tension at the wound.

Improvements have been made to traditional skin stretchers. Chinese patent document CN201711065999.8 introduces a "tension-measurable and adjustable skin stretch stapler". The device includes a force-measuring structure and two sets of skin stretch structures distributed on both sides of the force-measuring structure, and the force-measuring structure adopts a spring dynamometer. Although the device can measure the tension of the skin at the wound site, it is still a skin stretcher, which is used to stretch the skin to close the wound, rather than specifically measuring the tension of the wound skin. In addition, the measuring device adopts a spring dynamometer, which is relatively bulky and inaccurate in measuring force, especially for the part with small wound skin tension, the wound skin tension cannot be accurately measured.

Therefore, it is the background of the present utility model to research a measuring device mainly used to accurately measure the skin tension of the wound site, and can measure the skin tension of different sizes, and can assist the medical device for skin stretching when necessary.

The device can accurately measure the size of the wound skin tension, which makes up for the lack of an accurate measurement of the wound tension device in clinical practice.

(2) The skin traction device of the present invention is simple in structure, light in weight, easy to install, has little influence on the skin tension during measurement, and is easy to remove after the measurement. If not removed, it can also be used as a kind of skin after measuring the tension The traction device continues to stretch.

(3) The force measuring device of this device adopts a pressure sensor. Compared with the traditional spring dynamometer, the data measured by the pressure sensor is more accurate, and the weight of the device is reduced, and the influence of the device is too large on the wound. affect the force measurement results.

Detailed ways

The present utility model will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1:

The skin tension measuring device includes a force measuring device and a set of skin stretching devices which can be fixed on both sides of the wound skin. The skin stretching device includes two fixing feet 1 for fixing on the skin on both sides of the wound, a connecting rod 2 connecting the two fixing feet 1, a pusher 3 for pushing the two fixing feet 1 to slide on the connecting rod 2, and pushing the The locking structure 4 on the piece 3. The pusher 3 is in the shape of a thread. When the pusher 3 is rotated, the two fixing feet 1 can approach in the direction of the thread to close the wound. When the wound is closed, the locking structure 4 is used for locking.

Further, two fixing feet 1, which can be used to fix the skin on both sides of the wound, are composed of a needle holder and two side-by-side metal sheets connected above it. The direction of the metal sheets is perpendicular to the direction of the needle holder. Holes, with 1cm space between 2 metal pieces. The metal sheet can be well adhered to the skin surface, and is fixed on the skin by adhesive tape or suture.

Further, the two needle holders are connected as a whole by two connecting rods 2 . The connecting rod 2 is a metal rod with a diameter of about 2mm, one end is fixed with the needle holder, and the other end passes through the needle holder, so that the needle holder can move freely on the connecting rod without resistance. The middle of the two connecting rods 2 is a pusher 3, and the pusher 3 is a threaded metal rod, passing through the needle holder from the center of the two connecting rods 2, and by rotating the locking structure 4 at the end, the fixed foot on one side is pushed to the other. Move in the direction until the skins on both sides meet.

Further, the force measuring device is a pressure sensing force measuring device. A spring 5 is installed on the other end of the pusher 3 (the opposite side of the locking structure), and a pressure sensor 6 is installed at the rear end of the spring 5 . The other end of the pressure sensor 6 is connected to the display 7 . Under the condition that the skin wound is naturally opened without any external force, the spring on one side of the pressure sensor 6 is completely relaxed, there is no pressure on the pressure sensor 6, and the reading is zero. When the locking structure 4 at the end of the pusher 3 is rotated, the wound will be closed under the action of tension, and at the same time, the spring 5 at the end of the pusher 3 will be compressed, compressing the pressure sensor 6, so as to feel the pressure, and finally the pressure sensor 6 is displayed in numerical form The size of the output pressure indirectly reflects the size of the wound skin tension.

The working principle of the utility model:

In use, the two fixing feet 1 are respectively fixed on both sides of the skin wound, and the metal sheet on the fixing feet 1 can be well attached to the skin surface, and is fixed on the skin by adhesive tape or suture. When the tension is particularly high, a Kirschner wire can also be used to pass through the metal sheet on the fixing foot 1 and then pass through the skin on both sides of the wound to be fixed on the wound.

After the two fixing feet 1 are tightly fixed with the skin on both sides of the wound, the locking structure 4 on the pusher 3 is adjusted so that the locking structure 4 is at the initial position of zero tension in the wound. At this time, the wound is naturally opened without any external force, the two fixing feet 1 are located on both sides of the wound, and the locking structure 4 is abutted on the fixing feet 1 . The spring 5 at the other end is in a fully relaxed state, the pressure sensor 6 does not receive any pressure and the reading is zero.

When the tension needs to be measured, the locking structure 4 on the pusher rod 3 is rotated to make the skin on both sides of the wound close under the push force. At this time, the spring 5 at the other end of the pusher rod 3 will be infected with pressure, compress and deform, and the spring The baroreceptor 6 at the end of 5 will specifically display the pressure value it feels. When the skins of the wounds on both sides are completely abutted, the locking structure 4 is stopped at this time, and the pressure felt by the other pressure sensing device of the push rod 3 is the tension of the skin wound.
