Researchers developed a novel device to measure skin tension during surgery. This compact tensiometer accurately quantifies forces, potentially improving surgical outcomes and minimizing scarring.

Area of Science:

  • Biomedical Engineering
  • Surgical Technology

Background:

  • Accurate measurement of in vivo skin tension is crucial for surgical success.
  • Existing methods for assessing skin tension are often subjective or cumbersome.

Purpose of the Study:

  • To develop and validate a simple, quantitative device for measuring skin tension across surgical incisions.
  • To assess the feasibility of using this device in clinical surgical settings.

Main Methods:

  • A semicircular stainless steel stress member with strain gauges in a Wheatstone bridge configuration was designed.
  • The device was calibrated using known forces ranging from 0.5 to 500 grams.
  • Surgical tests were conducted to evaluate ease of use, time efficiency, and compactness.

Main Results:

  • The device reliably measured forces from 0.5 to 500 grams with a calibration curve established.
  • Surgical tests demonstrated the device is easy to use, quick to operate, and compact.
  • The strain gauges functioned optimally within their five percent dynamic range.

Conclusions:

  • The developed tensiometer provides a quantitative method for assessing in vivo skin tension.
  • This device may assist in determining optimal suture strength and incision direction to minimize scarring.
  • Further application could lead to more objective descriptions of surgical wound healing and tension dynamics.
