We dealt with bi-directional cog threads in the previous chapter. In this chapter, we introduce bi-directional threads with cones rather than cogs. This method is convenient for performing without a cannula as the two ends of the thread are connected to a needle. This type of thread is called as a thread with a bi-directional needle. Silhouette Soft® is a representative one.
