摘要:
A surgical trocar assembly with a marker element is disclosed. The assembly comprises a trocar, a handle, and a marker element. The trocar is constructed as an elongated member defined by distal and proximal ends. The distal end further includes a tissue piercing tip. The marker element defines a shoulder and includes at least one contacting member that extends in a distal direction from the shoulder. The contacting member is configured to contact a surface of tissue adjacent an incision site created by the tissue piercing tip so as to provide a visual indication of the incision site when the trocar is removed from the incision site.
