Size of Laparoscopic Trocars:
Laparoscopic trocars come in different sizes, ranging from 2mm to 15mm in diameter. The size of the trocar used depends on the size of the instrument that needs to be inserted and the size of the patient.

How to Use Laparoscopic Trocars:
The patient is placed under general anesthesia.
The surgeon makes a small incision in the abdominal wall.
The trocar is inserted through the incision and into the abdominal cavity.
Once the trocar is in place, the surgeon can use it to insert other surgical instruments.
After the surgery is completed, the trocar is removed from the incision site

How to Avoid Damage:
Laparoscopic trocars can cause damage to internal organs if not used correctly.
Some of the steps that can be taken to avoid damage are:
Use the appropriate size trocar for the patient and instrument being used.
Ensure that the trocar is inserted at the correct angle to avoid damaging internal organs.
Use caution when inserting and removing the trocar to avoid accidental damage.
Use an optical trocar to provide visual feedback during the insertion process.
Monitor the patient closely for any signs of internal bleeding or organ damage.

How to do sterilization:
Reusable trocars must be appropriately sterilized before each use to prevent the transmission of infectious agents.
The trocar should be disassembled and cleaned thoroughly, then sterilized using methods such as steam autoclaving, ethylene oxide gas, or hydrogen peroxide plasma.
The manufacturer’s instructions should be followed to ensure proper sterilization and maintenance of the trocar.
