[0002] During wound healing, wound tension plays a crucial role in both healing and scar formation. However, there is currently no readily available device for measuring wound tension, and clinical assessment relies solely on experience, which has the following limitations: Inaccurate measurements: Traditional wound tension estimation may rely solely on subjective judgment and cannot provide accurate values.

[0003] Complex operation: Existing measuring equipment may be bulky and complex to operate, making it inconvenient for medical staff to use quickly in clinical settings.

[0004] Lack of portability: Some devices need to be fixed in a specific location or require complex power support, making them unsuitable for use in hospitals at different levels.

[0005] Safety concerns: Some measurement methods cannot withstand high-temperature sterilization, which may contaminate the wound and pose a risk of wound infection.

[0006] Based on the above problems, designing a portable wound tension measuring instrument that can measure wound tension is of great practical significance. Utility Model Content

[0007] To address the problems existing in the prior art, this invention provides a portable wound tension measuring instrument.

[0008] The technical solution adopted by this utility model to solve this problem is: A portable wound tension measuring instrument includes an external support frame and a tension measuring structure, wherein: The measuring instrument's external support consists of a transverse support structure and longitudinal support structures located at both ends of the transverse support structure. A tension scale is installed on the transverse support structure. The tension measuring structure includes a movable indicating structure slidably mounted on a transverse support structure, a slide rail mounted between two longitudinal support structures, and a tension measuring component that slides freely on the slide rail. Each end of the tension measuring component is provided with a suture connector, and the two ends of the tension measuring component are respectively connected to the wound suture through the suture connector, so that the two ends of the tension measuring component are respectively fixed to both sides of the wound.

[0009] In the above technical solution, the longitudinal support structure on one side is fixedly connected to the transverse support structure as a fixed support, and the longitudinal support structure on the other side is connected to the transverse support structure as a movable support through locking screws.

[0013] In the above technical solution, the tension measuring component is a tension spring or a tension sensor.

[0014] In the above technical solution, when the tension measuring component is a tension spring, the tension spring is deformed and stretched under the traction of the skin on both sides of the wound.

[0029] A portable wound tension measuring instrument includes an external support frame and a tension measuring structure, wherein: The measuring instrument's external support consists of a transverse support structure 1 and longitudinal support structures 2 set at both ends of the transverse support structure 1. A tension scale 3 is set on the transverse support structure 1, and the tension scale 3 is a detachable tension scale. The tension measuring structure includes a movable indicating structure slidably mounted on a transverse support structure 1, a slide rail 5 positioned between two longitudinal support structures 2, and a tension spring 13 that slides freely on the slide rail 5. Each end of the tension spring 13 is equipped with a suture connector, and both ends are connected to the wound suture via the suture connectors, thus fixing both ends of the tension spring 13 to both sides of the wound. Under the traction of the skin on both sides of the wound, the tension spring deforms and is stretched. An overall moving measuring instrument is used to align one end of the tension spring 13 with the "0" point of the tension scale 3, and then the tension of the tension spring is measured by the sliding movable indicating structure to obtain the wound tension.

[0030] Furthermore, in this embodiment, one of the longitudinal support structures 2 on one side is fixedly connected to the transverse support structure 1 as a fixed support, and the other longitudinal support structure 2 on the other side is connected to the transverse support structure 1 as a movable support through locking screws 6. The longitudinal support structure 2 is provided with slide rail fixing holes 4 for the end of the slide rail 5 to be adapted and connected.

[0031] Furthermore, in this embodiment, the movable indicator structure can be composed of a movable structure 10 and an indicator structure 11. The movable structure 10 has a sliding hole 12 that is adapted to slide with the transverse support structure 1 and the observation window 8. The inner contour shape of the sliding hole 12 is the same as the outer contour shape of the transverse support structure 1 and the observation window 8. The indicator structure 11 is an indicator needle, an indicator rod, or an indicator plate.

[0032] Furthermore, in this embodiment, the bottom of the indicator rod may be provided with a sliding hole that is adapted to slide along the slide rail.

[0033] In this embodiment, a portable wound tension measuring instrument includes five parts: a detachable tension scale 3, a movable indicating structure, a slide rail 5, a tension spring 13, and an external support for the measuring instrument. The measuring instrument's outer bracket has a ruler groove and a slide rail fixing hole for fixing the detachable tension scale 3 and slide rail 5. It can also be disassembled to facilitate the replacement of tension scale 3 with different amounts and tension spring 13 with different tensions. The tension spring 13 and tension scale 3 can be replaced according to different actual usage requirements. The detachable tension scale 3 is used to mark the tension represented by the tension spring 13 after stretching. It is set to 0 point with an accuracy of 0.1N and a range of 1N (different tension scales can be replaced depending on the accuracy and range of the tension spring). The movable indicator structure can slide freely on the outer bracket and is aligned with the end of the tension spring 13 for reading when in use; The slide rail and tension spring 13 can slide freely on the slide rail 5. Two fixing holes are located on both sides of the spring, allowing the wound sutures to fix both ends of the spring to the sides of the skin defect. Under the traction of the skin on both sides of the wound, the spring deforms and is stretched. The overall moving measuring instrument allows the scale to slide relative to the spring, aligning one end of the spring with the 0 point. Sliding the indicator needle allows measurement of the spring tension at this point.

[0034] The portable wound tension measuring device described above has the following advantages: ①: A high-sensitivity tension spring is used, which can deform in accordance with the tension of the skin, improving the measurement accuracy of the measuring instrument for wound tension and enabling more accurate capture of wound tension changes.

[0035] ②: All tension springs have fixing holes, which can be tightly fixed to the wound skin using wound sutures, so that the length of the spring can better fit the natural expansion range of the wound and better reflect the tension of the wound.

[0036] ③: The tension spring can move freely and parallel on the slide rail, reducing the reaction force of the measuring instrument on the natural expansion of the wound, making the obtained measurement data more accurate.

[0037] ④: Both the tension scale and the tension spring are detachable parts. Different tension springs and scales can be used according to clinical needs, which can basically meet the measurement needs of all tension wounds.

[0038] ⑤: This measuring instrument has a simple and ingenious structure. It is made entirely of metal materials and can withstand high-temperature sterilization. It can meet the strict sterilization requirements during surgery and has great practical value. It can be widely used in the clinical work of many hospitals.

[0039] ⑥: In terms of technology, the measuring instrument has a relatively simple structural design, making its manufacturing process easier to control. It can accurately produce qualified products according to design requirements, reduce production errors and defect rates caused by high technical difficulty, and ensure the quality stability of the device.

[0040] ⑦: In terms of economic cost, the manufacturing process of this measuring instrument is simple, and the cost of raw materials, equipment and labor required is relatively low. For manufacturers, this allows for effective cost control during large-scale production, increasing the profit margin of the product and enhancing the price competitiveness of the measuring instrument in the market. This facilitates the promotion of the product to clinical applications in hospitals at all levels at a more affordable price.

[0041] ⑧: Regarding the feasibility of promoting this measuring instrument: The measuring instrument is simple to operate, easy to learn and operate, and has low skill requirements for clinicians, which is conducive to its promotion in clinical applications in hospitals at all levels. Example 2

[0042] Embodiment 2 of this utility model is a further improvement on Embodiment 1 in order to fully leverage the technical advantages of the present invention. The following is an illustrative example.

[0043] For example, the tension spring 13 is provided with a thread connector at both ends. The thread connector is an annular fixing hole 14. The annular fixing hole 14 has a locking slit 15 obliquely opened on its annular body. When fixing the thread, the thread is passed through the annular fixing hole and then knotted for fixation. Alternatively, the thread can be passed back and forth through the annular fixing hole and then inserted into the locking slit for fixation. The operation is simple. Example 3

[0044] A portable wound tension measuring instrument includes an external support frame and a tension measuring structure, wherein: The measuring instrument's external support consists of a transverse support structure 1 and longitudinal support structures 2 set at both ends of the transverse support structure 1. A tension scale 3 is set on the transverse support structure 1. The tension measurement structure includes a movable indicating structure slidably mounted on a transverse support structure 1, a slide rail 5 mounted between two longitudinal support structures 2, and a tension sensor that slides freely on the slide rail 5. Each end of the tension sensor is provided with a suture connector, and the two ends of the tension sensor are respectively connected to the wound suture through the suture connector, so that the two ends of the tension sensor are respectively fixed to both sides of the wound. The tension sensor measures the traction force of the skin on both sides of the wound, thereby obtaining the wound tension. Example 4

[0045] Embodiment 4 of this utility model is a further improvement on Embodiment 1 in order to fully leverage the technical advantages of the present invention. The following is an illustrative example.

[0046] For example, both the transverse support structure 1 and the longitudinal support structure serving as movable support are provided with grooves 7 for inserting tension scale 3. An observation window 8 is provided in front of the groove 7 on the transverse support structure 1, and a screw fixing hole is provided in front of the groove 7 on the longitudinal support structure 2. The tension scale 3 is fixed by locking screws 9. By unlocking the locking screws 9, the tension scale 3 can be inserted into the measuring instrument through the groove. Then, the tension scale 3 is locked by locking screws 9, thus realizing the detachable installation and replacement of tension scale 3.

[0047] Furthermore, in this embodiment, the transverse support structure 1 may have a tension scale storage cavity 16 and a tension spring storage cavity 17. The longitudinal support structure 2, which serves as a movable support, may have a corresponding tension scale storage port 18 and a tension spring storage port 19. The longitudinal support structure 2 may also have a cover 20 for closing or opening the tension scale storage port 18 and the tension spring storage port 19. One end of the cover 20 is rotatably connected to the longitudinal support structure 2 via a hinge, and the other end is connected to the longitudinal support structure 2 via a locking screw 21. The tension scale storage cavity 16 is used to store spare tension scales 3. Taking this embodiment as an example, the tension scale storage cavity 16 can store three tension scales 3, each with a different range. The tension spring storage cavity 17 can store three tension springs 13, each with a different tension. The appropriate tension scale 3 and tension spring 13 can be taken out and installed as needed. The remaining tension scales 3 and tension springs 13 are then stored. Finally, the cover 20 is locked with the cover screw 21.

[0048] Furthermore, in this embodiment, the tension scale storage cavity 16 may contain various tension scales 3 with different ranges, and the tension spring storage cavity 17 may contain various tension springs 13 with different tensions. Each tension scale 3 with a different range corresponds to a tension spring 13 with a specific tension. The corresponding tension scales and tension springs are matched in sets and have the same color markings, making it easy for the operator to take out and install the appropriate range tension scale 3 and tension spring 13 with the same color markings as needed. Example 5

[0049] Embodiment 5 of this utility model is a further improvement on Embodiment 1 in order to fully leverage the technical advantages of the present invention. The following is an illustrative example.

[0050] For example, an illumination bulb 22 is provided on the side of the transverse support structure 1 near the slide rail 5, and an illumination bulb 22 is provided on the side of the movable indicator structure near the tension scale 3. The illumination bulb 22 can be powered by a button battery and is equipped with a switch. When the illumination bulb 22 on the transverse support structure is turned on, it can provide illumination to the wound area, which is convenient for suture fixation; when the illumination bulb 22 on the movable indicator structure is turned on, it can provide illumination to the tension scale, which is convenient for viewing the tension scale.

[0051] Working Principle: The portable wound tension measuring instrument consists of an external support frame, a detachable tension scale, a movable indicating structure, a slide rail, and a tension spring. The tension spring and scale can be replaced according to actual usage needs. The tension spring can move freely on the slide rail. Two fixing holes are located on both sides of the spring, through which wound sutures can be used to fix both ends of the spring to the sides of the skin defect. Under the traction of the skin on both sides of the wound, the spring deforms and stretches. Moving the measuring instrument allows the scale to slide relative to the spring, aligning one end of the spring with the zero point. Sliding the movable indicating structure measures the tension of the spring at this point. This measuring instrument is simple to operate, easy to learn and use, requires relatively low skill from clinicians, and is conducive to its widespread clinical application in hospitals at all levels.
