Abstract
According to various implementations, a surgical instrument is provided that has two graspers for remotely grasping an organ or tissue in two different locations. The surgeon can manipulate the organ or tissue using the instrument with one hand while using his or her other hand to perform a surgical procedure. Using one instrument also reduces the number of incisions required. This instrument is especially useful in laproscopic procedures and other minimally invasive surgeries.
Claims34
A surgical instrument comprising:
- a handle configured for being held in one hand;
- an elongated portion extending from the handle substantially along an axis;
- a first pair of cooperating end effectors operatively disposed adjacent a distal end of the elongated portion;
- and
- a second pair of cooperating end effectors operatively disposed adjacent the distal end of the elongated portion,
- wherein the handle comprises:
- an extension mechanism configured for extending distal ends of the first pair of cooperating end effectors outwardly from the distal end of the elongated portion and laterally relative to the axis, and
- a linear extension mechanism configured for urging distal ends of the second pair of cooperating end effectors outwardly from the distal end of the elongated portion and substantially parallel to the axis.

A method of using a surgical instrument, comprising:
- providing a surgical instrument, the surgical instrument comprising a handle, an elongated portion extending from the handle along an axis, and first and second pairs of graspers disposed adjacent a distal end of the elongated portion;
- guiding at least a portion of the elongated portion of the surgical instrument through a small incision in a patient's body;
- remotely extending the first and second pairs of graspers away from the distal end of the elongated portion toward a tissue or organ in the patient's body;
- remotely positioning the first pair of graspers into a first position and the second pair of graspers into a second position;
- grasping the tissue or organ in a first location adjacent the first position;
- grasping the tissue or organ in a second location adjacent the second position, the first location being spaced apart from the second location;
- and
- after grasping the tissue or organ with the first and second pairs of graspers, moving the handle of the surgical instrument with one hand to manipulate the tissue or organ.
