Abstract
A method and device for providing a flexible and soft surgical trocar for use in laparoscopic procedures.
Claims12
A soft flexible surgical trocar configured for use with a laparoscope, comprising:
- a cylindrical handle with a hole traversing from a first side of the cylindrical handle to a second side of the cylindrical handle;
- a mounting element located adjacent the hole on the second side of the cylindrical handle;
- a trocar shaft connected to the mounting element and which extends away from the hole on the second side of the cylindrical handle;
- and
- a seal element mounted within the cylindrical handle defining an aperture for a sealed reception of the trocar shaft,
- wherein the trocar shaft is flexible and capable of being bent at an angle with respect to a longitudinal axis of said soft flexible surgical trocar, and wherein the trocar shaft terminates in an axial lumen,
- wherein said cylindrical handle is turned clockwise to cause said trocar shaft to bend at said angle with respect to said longitudinal axis of said soft flexible surgical trocar, and
- wherein when said soft flexible surgical trocar is used with a surgical trocar cannula said cylindrical handle is turned counterclockwise to cause said surgical trocar cannula to bend at a second angle with respect to a longitudinal axis of said soft flexible surgical trocar.
