Abstract
A suture trimmer including an elongate shaft including an elongate lumen extending proximally from a distal end of the elongate shaft, a transverse through-opening disposed proximal the distal end of the shaft, and a groove extending proximally from the distal end of the shaft to a distal end of the opening. A fitting is disposed within the elongate lumen at the distal end of the shaft and extends distally therefrom. A cutting member is slidably received within the lumen of the shaft and configured to move between a proximal end of the opening and the distal end of the opening and cut a suture disposed within and extending from the opening.
Claims14
A suture trimmer having a proximal end and a distal end, the suture trimmer comprising:
- an elongate shaft comprising an elongate lumen extending proximally from a distal end of the elongate shaft, the distal end of the elongate shaft being proximal a distal end of the suture trimmer;
- a fitting disposed within the elongate lumen at the distal end of the shaft and extending distally therefrom;
- a suture retainer movable within the elongate lumen and configured to move into a proximal portion of an opening of the fitting;
- and
- a cutting member slidably received within the lumen of the shaft and configured to cut a suture disposed within and extending from the opening of the fitting.
A suture trimmer having a proximal end and a distal end, the suture trimmer comprising:
- a shaft having a proximal end, a distal end, and a lumen extending proximally from the distal end of the shaft, the shaft including a transverse through-opening disposed proximal the distal end of the shaft, and a groove extending proximally from the distal end of the shaft to a distal end of the opening, the distal end of the elongate shaft being proximal a distal end of the suture trimmer;
- a fitting disposed within the lumen at the distal end of the shaft, the fitting comprising an opening extending from a distal end of the fitting to a proximal end of the fitting;
- a suture retainer movable within the elongate lumen and configured to move into a proximal portion of an opening of the fitting, the opening facing proximally towards the lumen;
- and
- a cutting member slidably received within the lumen of the shaft and configured to cut a suture disposed within and extending from the opening of the fitting.
A method for trimming suture, the method comprising:
- disposing a suture loop within tissue of a patient, the suture loop including at least one knot and two free ends;
- positioning the two free ends of suture in a suture trimmer, the suture trimmer having proximal end and a distal end and comprising:
- an elongate shaft comprising an elongate lumen extending proximally from a distal end of the elongate shaft, the distal end of the elongate shaft being proximal a distal end of the suture trimmer;
- a fitting disposed within the elongate lumen at the distal end of the shaft and extending distally therefrom;
- a suture retainer movable within the elongate lumen and configured to move into a proximal portion of an opening of the fitting;
- and
- a cutting member slidably received within the lumen of the shaft and configured to cut a suture disposed within and extending from the opening of the fitting;
- and
- actuating the cutting member within the suture trimmer, the cutting member configured to sever the suture extending from the opening.
