摘要： A surgical suturing apparatus is described. The suturing apparatus has a needle having at least one pointed end, a channel for releasably receiving the needle, a needle positioning assembly having members for moving the needle and an actuation assembly for actuating the needle positioning assembly. The needle includes a first puncturing point at a proximal end thereof and an engagement section adjacent thereto, a distal end, which may have a second puncturing point, and another engagement section adjacent the distal end. A structure, such as an eye or a slot, is provided to secure a length of suture material to the needle. The members for moving the needle include an engagement member for releasably engaging one of the engagement sections of the needle to effect axial movement of the needle within the channel, a ramp member for effecting movement of the needle in the distal direction along the longitudinal axis of the channel and for urging the proximal end of the needle out of the channel, and a snare axially movable within the channel and having a portion releasably housed within the channel. The snare portion is configured for capturing the proximal engagement section of the needle to guide the needle in a proximal direction when the needle is out of the channel and to guide the return of the needle to the channel.
