Experimental Study on the Process and Performance of
Pre-dressing-assisted Laser Joining of Vascular Tissues
Abstract
Blood vessels are an important part of the human circulatory system
[1-4]. In clinical surgery, the common method for
treating ruptured blood vessels is suturing, but this method can cause
inflammatory reactions [5-6]. With the
popularization of lasers, they have been widely used in the medical
field. However, due to the poor absorption of laser energy by tissues,
the tensile strength of tissues after joining is low. To further improve
the tensile strength after laser joining, this study analyzed the law of
the effect of pre-dressing-assisted laser on the tensile strength and
thermal denaturation of vascular tissues after joining with different
components and concentrations by designing experiments. The experimental
results showed that the tensile strength of the joined tissues could
reach 50.978 KPa, and the degree of thermal denaturation was only 0.025,
which is of great significance for the study of laser-joined vascular
tissues.
