Abstract
An improved suture cutter for cutting high strength sutures used in arthroscopic surgeries includes a movable handle that moves rotationally around a pivot. This rotational motion is translated through a linkage into near linear movement at the distal end of a moving member. At the distal end, the moving member pushes a cutting blade onto an inclined stationary blade and thereby cuts a suture captured between the moving cutting blade and the inclined stationary blade.
Claims24
A suture cutting instrument comprising:
- a handle assembly comprising a stationary handle and a movable handle pivotally connected to said stationary handle at a pivot and wherein the movable handle moves rotationally around the pivot;
- a driver comprising a proximal end connected to the movable handle and being configured to reciprocate longitudinally when the movable handle moves rotationally around the pivot;
- a suture cutting assembly comprising a movable cutting blade and an inclined stationary blade, wherein the movable cutting blade is connected to a distal end of the driver and is configured to move longitudinally onto the inclined stationary blade when the movable handle moves rotationally around the pivot and thereby to cut a suture captured between the movable cutting blade and the inclined stationary blade.
A method for cutting a suture comprising:
- providing a handle assembly comprising a stationary handle and a movable handle pivotally connected to said stationary handle at a pivot and wherein the movable handle moves rotationally around the pivot;
- providing a driver comprising a proximal end connected to the movable handle and being configured to reciprocate longitudinally when the movable handle moves rotationally around the pivot;
- providing a suture cutting assembly comprising a movable cutting blade and an inclined stationary blade, wherein the movable cutting blade is connected to a distal end of the driver and is configured to move longitudinally onto the inclined stationary blade when the movable handle moves rotationally around the pivot and thereby to cut a suture captured between the movable cutting blade and the inclined stationary blade.
