摘要:
A surgical suturing device having an axis extending between a proximal end and a distal end is operable to move a suture through body tissue. An actuating rod extends between the handle assembly and the shaft. A needle assembly at the distal end of the actuating rod is movable with the actuating rod between an extended state and a retracted state. Bifurcated portions of the needle assembly define a suture slot, the bifurcated portions have a proximate relationship when the needle assembly is in the retracted state and having a separated relationship when the needle assembly is in the extended state. The needle assembly is biased to the retracted state and the bifurcated portions are biased to the separated relationship. A handle assembly is configured to releasably receive the needle assembly and is operable to move the needle assembly between a free suture state and a captured suture state.
