Jawed trocar assembly

A method of inserting an endoscopic tool assembly into a body cavity, the endoscopic tool assembly comprising an endoscopic tool insertable into a trocar assembly comprising a hollow elongate member having a first end and a second end, a pair of jaws hingedly coupled to the second end of the hollow elongate member, wherein the pair of jaws has at least a rest position wherein at least a first jaw of the pair of the jaws is substantially parallel to a longitudinal axis of the hollow elongate member and an expanded position wherein the first jaw is rotated so that an end of the fist jaw is positioned radially away from the longitudinal axis;

• each jaw of the pair of jaws hingedly coupled opposite one another;
• a first slider coupled to the first jaw, such that the first slider is axially translatable with respect to the first jaw;
• a penetrating member at a first end of the slider, the penetrating member configured to penetrate at least one layer of body tissue;
• and a first scope cleaner coupled to a second end opposite to the first end of the first slider, the first scope cleaner being configured to sweep across an interior of the hollow elongate member when the first slider translates axially away from the second end of the first scope cleaner, the method comprising:
• making an incision through a first body tissue;
• inserting the trocar assembly through the incision;
• advancing the trocar assembly through the incision such that the pair of jaws of the trocar assembly engages a second body tissue;
• urging the trocar assembly against the second body tissue to penetrate through the second body tissue;
• inserting the endoscopic tool through the trocar assembly;
• advancing the endoscopic tool through the trocar assembly beyond the second end of the elongate hollow member, thereby transitioning the trocar assembly from the rest position to the expanded position;
• extending the endoscopic tool beyond the end of the jaw.

A method of cleaning an endoscopic tool assembly inserted into a body cavity, the endoscopic tool assembly comprising an endoscopic camera inserted into a trocar assembly comprising a hollow elongate member having a first end and a second end, a pair of jaws hingedly coupled to the second end of the hollow elongate member, wherein the pair of jaws has at least a rest position wherein at least a first jaw of the pair of the jaws is substantially parallel to a longitudinal axis of the hollow elongate member and an expanded position wherein the first jaw is rotated so that an end of the first jaw is positioned radially away from the longitudinal axis;

• each jaw of the pair of jaws hingedly coupled opposite one another;
• a first slider coupled to the first jaw, such that the first slider is axially translatable with respect to the first jaw;
• a penetrating member at a first end of the first slider, the penetrating member configured to penetrate at least one layer of body tissue;
• and a first scope cleaner coupled to a second end opposite to the first end of the first slider, the first scope cleaner being configured to sweep across an interior of the hollow elongate member when the first slider translates axially away from the second end of the first scope cleaner, the method comprising:
• urging the trocar assembly against a body tissue to penetrate through the body tissue;
• inserting the endoscopic camera through the trocar assembly;
• advancing the endoscopic camera through the trocar assembly beyond the second end of the elongate hollow member, thereby transitioning the trocar assembly from the rest position to the expanded position;
• extending the endoscopic camera beyond the end of the jaw to expose a lens of the endoscopic camera to the body cavity;
• retracting the endoscopic camera into the elongate hollow member, thereby transitioning the trocar assembly from the expanded position to the rest position;
• engaging the lens with the scope cleaner, thereby cleaning debris off of the lens.
