Laparoscopic retractable dissector and suture and needle passer
First Claim
1. A device, comprising:
- a cannula;
a handle slidably disposed within said cannula; and
an extendable member in mechanical communication with said handle, such that axial and rotational movement of said handle with respect to said cannula results in corresponding axial and rotational movement of said extendable member, respectively, said extendable member having a curvature when extended from an interior of said cannula and having at least one hole disposed therein.

Abstract
Described herein is a device that may be used in various applications, such as medical applications, and, particularly in laparoscopic procedures, to manipulate and/or introduce objects within or into the body. In one embodiment of the invention, a device includes a cannula with a handle that remains exterior to the body and an extendable member on a portion of the device that may be inserted into the body. The handle, which controls the extendable member, may be moved in an axial direction to extend or retract the extendable member from the interior of the cannula. It may also be rotated to swivel the extendable member. Furthermore, the extendable member may include at least one hole that may be used to, for example, grasp a surgical suture or suture needle. Thus, the device may be used to introduce such objects into the body and manipulate them therein.

16. A method for introducing a surgical suture into a body, comprising:
-
providing a device, comprising;
a cannula, a handle slidably disposed within said cannula, and an extendable member in mechanical communication with said handle, such that axial and rotational movement of said handle with respect to said cannula results in corresponding axial and rotational movement of said extendable member, respectively, said extendable member having a curvature when extended from an interior of said cannula and having at least one hole disposed therein;
extending said extendable member;
inserting said surgical suture through said hole;
retracting said extendable member; and
inserting a distal end of said device into said body to introduce said surgical suture therein. - View Dependent Claims (17)

18. A method for manipulating a surgical suture within a body, comprising:
-
inserting a device into said body, said device comprising;
a cannula, a handle slidably disposed within said cannula, and an extendable member in mechanical communication with said handle, such that axial and rotational movement of said handle with respect to said cannula results in corresponding axial and rotational movement of said extendable member, respectively, said extendable member having a curvature when extended from an interior of said cannula and having at least one hole disposed therein;
extending said extendable member;
inserting a suture needle attached to said surgical suture through said hole;
disconnecting said suture needle from said surgical suture;
retracting said extendable member; and
manipulating said surgical suture within said body with said device. - View Dependent Claims (19, 20)
