![]() Instruments such as scissors and graspers are introduced using surgical trocars. These instruments play an important role in laparoscopic surgery. Trocars are now referred to as both the initial entry device as well as the hollow cannula used during the operation. Trocars are typically placed inside hollow cannulas and introduced inside body cavities to assist in draining fluids. A trocar is shaped like a pen and has a sharp triangular point. TrocarĪlong with the probe, scalpel, and cannula the trocar is one of the oldest implements used by medical practitioners. The instrument is classified as straight or curved depending upon the shape of the jaws. Needle holders have three parts – the jaws, joints, and handles. ![]() Suturing can often be tricky to use owing to the property of “memory” which causes tissue to resist deformation. Forming slip-knots to close wounds and surgical incisions requires precise skills. Needle DriverĪ needle holder is used by laparoscopic surgeons to hold suturing needles when closing wounds. Today, scopes are more like an apparatus with multiple parts that include a CCD camera, viewing device, lens cleaner, and an energy-supply device. Modern surgical laparoscopes used for minimally invasive procedures are a far cry from the simple hollow tubes that gradually developed to include lenses for magnified vision. Surgical scopes are one of the oldest instruments used by medical practitioners since ancient times. Common instruments used during laparoscopic procedures include a: laparoscope, needle driver for suturing, trocar, bowel grasper and surgical mesh. Inert gases like carbon dioxide are used to inflate the abdominal region which increases the distance between the organs and the abdominal wall thus enlarging the operating field. Laparoscopic instruments are used along with a laparoscope, which is a thin telescope fitted with a cold light source and a video camera. A variety of tips are available for manipulating the tissue and handle styles may allow ergonomic rotating, grasping and locking abilities in a precise fashion. Sizes typically range from 3 mm, 5 mm and 10 mm sizes. Instruments all have a very narrow shaft so that they can fit inside laparoscopic ports. Laparoscopic Instruments for a variety of purposes Laparoscopic instruments are made of durable materials and usually high quality stainless steel. Laparoscopic surgery uses long-pencil like instruments that fit through small cuts in the abdominal wall instead of large incisions required during open operations.
