Matrix-Assisted Laser Desorption Ionization (MALDI)01:08

Matrix-Assisted Laser Desorption Ionization (MALDI)

1.2K
Matrix-assisted laser desorption ionization (MALDI) is a powerful analytical technique used in mass spectrometry. It enables the identification and characterization of various biomolecules, including proteins, peptides, nucleic acids, and carbohydrates. MALDI is an ionization technique, widely employed in biological and medical research, as well as in fields like pharmacology and biochemistry.The analyte of interest, a biomolecule or a mixture of biomolecules, is mixed with a suitable matrix...

Tissues

Cells with similar structure and function are grouped into tissues. A group of tissues with a specialized function is called an organ. There are four main types of tissue in vertebrates: epithelial, connective, muscle, and nervous.

Tissues

67.5K
Tissues are a group of cells that share a common embryonic origin. Microscopic observation reveals that the cells in a tissue share morphological features and are arranged in an orderly pattern to perform specific functions. From an evolutionary perspective, tissues appear in more complex organisms. Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is...

Plant Cells and Tissues

65.7K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Tissue Membranes01:27

Tissue Membranes

8.3K
A tissue membrane is a thin layer of cells that covers the outside of the body, the organs, internal passageways that lead to the exterior of the body, and the lining of the moveable joint cavities. There are two basic types of tissue membranes— connective tissue and epithelial membranes.
Connective Tissue Membranes
The connective tissue membrane is formed solely from connective tissue. These membranes encapsulate organs, such as the kidneys, and line our movable joints. A synovial...

Area of Science:

  • Biomedical Engineering
  • Surgical Technology
  • Robotics

Background:

  • Effective surgical incision closure is vital, yet current methods like sutures and clips have limitations, particularly in minimally-invasive surgery.
  • Laser tissue soldering presents a promising alternative but faces challenges with reproducibility.
  • Existing robotic systems offer precision but require integration with advanced closure techniques.

Purpose of the Study:

  • To develop and demonstrate a robot-assisted laser soldering system for enhanced surgical incision closure.
  • To evaluate the feasibility and efficacy of this integrated system in ex-vivo tissue models.
  • To improve the reproducibility and effectiveness of laser tissue soldering in surgical applications.

Main Methods:

  • Integration of a previously developed laser soldering system with a robotic platform.
  • Demonstration of the combined system for incision closure on ex-vivo mouse skin samples.
  • Quantitative assessment of the mechanical strength of the closed incisions.

Main Results:

  • The robot-assisted laser soldering system was successfully demonstrated on ex-vivo mouse skin.
  • Closed incisions achieved an average tearing force of approximately 2.5N.
  • This represents 73% of the tearing force of intact, unincised mouse skin, indicating significant wound strength.

Conclusions:

  • Robot-assisted laser soldering is a feasible technique for surgical incision closure.
  • The system significantly enhances the mechanical integrity of closed incisions compared to sutures or clips.
  • This technology has the potential to improve reproducibility and revolutionize surgical tissue bonding, especially in minimally-invasive procedures.
