The invention discloses a
soft tissue separation preparation prepared from
elastin-like polypeptide and an application of the
soft tissue separation preparation and belongs to a medicinal preparation product and application of the
elastin-like polypeptide. The
soft tissue separation preparation prepared from
elastin-like polypeptide is liquid pharmaceutical preparation which is obtained by dissolving elastin-like polypeptide air dried flocculent
solid substances in
phosphate buffer solution and has the final concentration of 500-1000mu M; and the application of the soft tissue separation preparation comprises the step of enabling a
gastrointestinal tract submucous layer to be filled with the liquid pharmaceutical preparation, and an elastin-like polypeptide phase is changed to be gelatinous, so that a
gastrointestinal mucosa layer is fully separated from an muscularis propria. After the filling agent is injected,
gastrointestinal tract soft tissue separation distance is obviously increased, separation
duration time is prolonged,
multiple injection does not need to be carried out; the soft tissue separation preparation has good
biocompatibility; and the soft tissue separation preparation has degradable characteristic, and worry of residual foreign matters is eliminated, so that the soft tissue separation preparation prepared from elastin-like polypeptide is applicable to soft tissue isolation during treatment under a gastroendoscope,
lesion tissues of digestive tracts can be conveniently
cut off, and operation is safe and effective.
