Abstract
A tensioning device includes an elongate plunger, a plunger track housing configured to receive the plunger therein at least in part, an elongate tube configured to be coupled to the plunger track housing, and an actuator configured to cause axial translation of at least a portion of the plunger within the plunger track housing.
Claims18
A tensioning device comprising:
- an elongate plunger;
- a plunger track housing configured to receive the plunger therein at least in part, the plunger including first radially-projecting screw threading that is radially flattened over at least one circumferential segment of the plunger, the plunger track housing including an axial opening having a truncated circle shape and configured to fit the plunger therein;
- an elongate tube configured to be coupled to the plunger track housing;
- and
- an actuator configured to cause axial translation of at least a portion of the plunger within the plunger track housing, the actuator including second screw threading configured to made with the first screw threading of the plunger.

A method for tensioning sutures in a patient in need thereof, the method comprising:
- drawing a suture through one or more channels of a suture-tensioning device;
- fixing the suture to a plunger component of the suture-tensioning device, the plunger component including an elongate shaft with radially-oriented outer threading, the elongate shaft having a cross-sectional shape of a circle with at least one flat side;
- and
- adjusting a relative axial position between the plunger component and a plunger track component of the suture-tensioning device by rotating an actuator about an axis of the plunger track component to thereby adjust a tension of a portion of the suture, the actuator including radially-oriented inner threading configured to engage with the outer threading of the elongate shaft of the plunger component;
- wherein the plunger track component includes an axial inner channel dimensioned to receive at least a portion of the elongate shaft of the plunger component, the axial inner channel having at least one flat edge configured to contact the at least one flat side of the elongate shaft of the plunger component to restrain rotational movement of the plunger component relative to the plunger track component.
