A Trocar Is A Specialized Surgical Instrument Employed In Minimally Invasive Procedures, Particularly During Laparoscopic Surgeries. It Consists Of A Pointed, Cylindrical Shaft With A Handle At One End And A Sheath At The Other. Trocars Are Designed To Create A Controlled Entry Point, Allowing For The Insertion Of Various Laparoscopic Instruments Into The Body Through Small Incisions.
The Pointed End Of The Trocar Is Typically Covered By A Protective Sleeve During Insertion To Prevent Accidental Injury To Surrounding Tissues. Once The Trocar Is Properly Positioned, The Sleeve Is Removed, Leaving A Clear Pathway For The Insertion Of Additional Instruments, Such As Laparoscopes, Graspers, Scissors, Or Other Tools Necessary For The Surgical Procedure.
Trocar Sizes May Vary Depending On The Specific Surgical Application And The Instruments To Be Introduced. Some Trocars Are Designed With Features Such As A Valve Or Seal To Maintain Pneumoperitoneum, The Insufflation Of Carbon Dioxide Into The Abdominal Cavity To Create A Working Space For The Surgeon.
In Summary, A Trocar Serves As The Entry Point For Laparoscopic Instruments, Allowing Surgeons To Perform Minimally Invasive Surgeries With Reduced Trauma To The Patient's Body Compared To Traditional Open Procedures
