Abstract
A suture passing instrument for manipulating and passing suture through a tissue is disclosed. 5 The instrument includes a handle, an elongate shaft extending from the handle, a hook movably disposed within the elongate shaft. The elongate shaft includes a distal portion having an open end. The hook is movable from a retracted configuration in which at least a portion the hook is situated within the elongate shaft, and a deployed configuration in which the hook extends distally from the open end. The hook is operatively coupled to an actuator of the handle via a 10 coupling member and the hook is moved from the retracted configuration to the deployed configuration be applying tension to the coupling member.
Claims17
A suture passing instrument comprising:
- a handle at a proximal end of the suture passing instrument, the handle having an actuator;
- a tubular shaft extending from the handle, the tubular shaft defining a longitudinal axis and comprising a distal portion having an opening;
- a hook movable along the tubular shaft longitudinal axis from a retracted configuration in which at least a portion of the hook is situated within the tubular shaft, and a deployed configuration in which the hook extends through the opening and external to the tubular shaft;
- and
- a coupling member operably coupled to both the hook and the actuator, the coupling member disposed within the tubular shaft and configured such that tension in a proximal direction on the coupling member moves the hook from the retracted configuration to the deployed configuration.
A suture passing instrument comprising:
- a handle at a proximal end of the suture passing instrument, the handle having an actuator;
- a tubular shaft extending from the handle, the tubular shaft defining a longitudinal axis and including a distal portion with an opening;
- a hook movable along the tubular shaft longitudinal axis from a retracted configuration in which the hook is situated within the tubular shaft, and a deployed configuration in which the hook extends through the opening and external to the tubular shaft;
- and
- a coupling member defining a flexible loop disposed within the tubular shaft, directly coupled to the hook and operably coupled to the actuator, the coupling member configured to move the hook to the deployed configuration by moving the coupling member in a proximal direction and also retract the hook to the retracted configuration by moving the coupling member distally.
