Embalming is a practice focused on preserving human remains. This process involves treating the body with various chemical solutions. Tools are necessary to facilitate this procedure, ensuring that preserving agents reach all areas of the body effectively.
Understanding the Trocar
A trocar is a specialized, sharp-pointed instrument used to access and treat the internal cavities of the body. It typically consists of a long, slender metal shaft with a pointed tip, often triangular or trephine-shaped. The shaft is hollow, allowing for the passage of fluids or the removal of contents. Trocars vary in length, with common sizes around 16 to 24 inches, and are constructed from durable materials like stainless steel.
Its Purpose in Embalming
The primary function of the trocar is to facilitate both aspiration and injection within the body’s internal cavities. After arterial embalming, which involves introducing preserving fluids into the circulatory system, the trocar removes gases and fluids that accumulate in the thoracic, abdominal, and pelvic cavities. This removal process, known as aspiration, addresses areas not fully reached by the arterial solution. Following aspiration, the trocar is then employed to inject concentrated cavity fluid, an embalming chemical, into these internal spaces. This ensures thorough preservation of the visceral organs.
The Process of Cavity Embalming
Cavity embalming involves the application of the trocar to treat internal organs, with the process typically beginning with a small incision near the navel. Through this incision, the trocar is inserted and directed to puncture and drain hollow organs such as the stomach, intestines, and bladder. An aspirator, which can be water-powered or electric, is connected to the trocar to create suction, drawing out contents from these cavities. After aspiration, cavity fluid is introduced into the thoracic and abdominal regions, often by gravity feed, ensuring comprehensive chemical treatment of the internal organs.
Why Cavity Embalming is Essential
Cavity embalming plays a complementary role to arterial embalming. This step prevents the decomposition of internal organs, which can otherwise lead to issues like gas buildup and distention. By removing internal fluids and gases and introducing preservative chemicals, cavity embalming controls microbial activity within the body’s core. Without this specialized treatment, the overall embalming process would be less effective, potentially compromising the body’s preservation and appearance over time.
