Description

Adjustable skin tension tester

Technical Field

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

Background

The skin tension at the wound site is directly related to whether the wound can be directly closed, which method and material should be selected for wound closure, and the degree of scar hyperplasia after wound healing. The simple and adjustable wound skin tension measuring device is manufactured, and has important guiding significance for clinical application and scientific research.

At present, no measuring instrument specially used for measuring the skin tension of wounds exists clinically. The skin stretching device which is used clinically at present aims at the problem that the wound has too high tension and can not be directly drawn together and sutured. In the traditional skin stretching device, a kirschner wire penetrates into two sides of a skin wound in parallel, and then the kirschner wires on the two sides of the wound are stretched by mechanical force to close the wound. The device aims to pull the skin to close the wound, but cannot measure the skin tension at the wound. It is known that the tension that the skin can bear is limited, and excessive tension can tear the skin and cause the risk of ischemic necrosis of the skin margin. Therefore, an adjustable apparatus for measuring the skin tension of a wound is needed to measure the skin tension of the wound.

There have been improvements to conventional skin retractors. Chinese patent document CN201711065999.8 introduces a tension measurable adjustable skin stretching anastomat. 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 dynamometer. Although the device can measure the tension of the skin at a wound site, the device is still a skin stretching device which is used for stretching the skin to close the wound, and is not specially used for measuring the skin tension of the wound. In addition, the measuring device adopts a spring dynamometer, is relatively heavy, and has inaccurate force measurement, especially for the part with small wound skin tension, the wound skin tension cannot be accurately measured.

It is therefore the background of the present invention to develop a measuring device which is primarily intended for the accurate measurement of the skin tension at a wound site and which is capable of measuring skin tensions of different sizes, and to provide a medical device which can assist in the stretching of the skin when necessary.

Drawings

FIG. 1 is a schematic diagram of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1:

the skin tension measuring device comprises a force measuring device and a set of skin stretching devices which can be fixed on two sides of the skin of a wound. The skin stretching device comprises two fixing feet 1 used for being fixed on the skin on two sides of a wound, a connectingrod 2 used for connecting the two fixing feet 1, a pushing piece 3 used for pushing the two fixing feet 1 to slide on the connectingrod 2, and a locking structure 4 arranged on the pushing piece 3. Propulsion piece 3 is the screw thread form, and when rotatory propulsion piece 3, two fixed feet 1 can be close to along the screw thread direction, make the wound closure, and when the wound reached the closure back, use locking structure 4 to lock.

Furthermore, two fixed feet 1 that can be used to fix on wound both sides skin comprise a needle frame and connect 2 sheetmetals of arranging side by side above it, and the sheetmetal direction is perpendicular with the needle frame direction, has the aperture on the sheetmetal, and the interval is 1cm between 2 sheetmetals. The metal sheet can be well attached to the surface of the skin and is adhered or sewed to the skin through the adhesive tape.

Further, the two needle frames are connected into a whole through two connectingrods 2. The connectingrod 2 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 middle of the two connectingrods 2 is provided with a propelling part 3, the propelling part 3 is a threaded metal rod, the needle frame penetrates through the centers of the two connectingrods 2, and the fixing foot on one side is pushed to move towards the other direction by rotating the locking structure 4 at the tail end until the skins on the two sides are involuted.

Further, the force measuring device is a pressure sensing force measuring device. A spring 5 is arranged at the other end (opposite to the locking structure) of the propelling part 3, and apressure sensor 6 is arranged at the tail end of the spring 5. The other end of thepressure sensor 6 is connected to a display 7. In the case of a skin wound which is free from any external force and which is naturally open, the spring on the side of thepressure sensor 6 is completely relaxed, and there is no pressure on thepressure sensor 6, which reads 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 the spring 5 at the tail end of the pushing piece 3 is pressed to press thepressure sensor 6, so that the pressure applied is sensed, and finally thepressure sensor 6 displays the pressure in a numerical mode, thereby indirectly reflecting the tension of the skin of the wound.

The working principle of the invention is as follows:

when the fixing foot device is used, the two fixing feet 1 are respectively fixed on two sides of a skin wound, the metal sheets on the fixing feet 1 can be well attached to the surface of the skin, and the fixing foot device is fixed on the skin through adhesive tape adhesion or suture. When the tension is particularly high, a kirschner wire can be used for penetrating through the metal sheet on the fixing foot 1 and then penetrating through the skin on two sides of the wound to be fixed on the wound.

After the two fixing feet 1 are tightly fixed with the skin on two sides of the wound, the locking structure 4 on the pushing piece 3 is adjusted to enable the locking structure 4 to be located at the initial position of zero tension of the wound. At the moment, the wound is naturally opened without any external force, the two fixing feet 1 are positioned at the two sides of the wound, and the locking structure 4 is tightly close to the fixing feet 1. The spring 5 at the other end is in a fully relaxed state and thepressure sensor 6 does not receive any pressure and reads zero.

When the tension needs to be measured, the locking structure 4 on the pushing rod 3 is rotated to enable the skin on two sides of the wound to be closed under the pushing force, the spring 5 at the other end of the rod of the pushing piece 3 is infected with pressure and is compressed and deformed, and thepressure sensor 6 at the tail end of the spring 5 displays the sensed pressure value specifically. When the skin of the wounds on the two sides is completely closed, the locking structure 4 stops being screwed at the moment, and the pressure sensed by the pressure sensing device on the other rod of the push rod 3 is the tension of the skin wound.
