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.
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.
The invention claimed is: 1. A surgical suturing apparatus comprising:a channel having a longitudinal axis, a distal end and a proximal end, said channel defining a housing at the distal end thereof having an opening therein;a needle releasably disposed within said housing, said needle having a dist
The invention claimed is: 1. A surgical suturing apparatus comprising:a channel having a longitudinal axis, a distal end and a proximal end, said channel defining a housing at the distal end thereof having an opening therein;a needle releasably disposed within said housing, said needle having a distal end, a proximal end, and a proximal puncturing point at the proximal end, said needle being structured for attachment to a length of suture material;a needle positioning assembly having members movable relative to said channel for effecting a desired number of release and retrieval cycles for releasing said needle from said housing and guiding the return of said needle to said housing; andan actuation assembly for controlling said members of said needle positioning assembly;wherein needle positioning assembly comprises (a) an engagement member configured for releasably engaging said needle to effect axial movement of said needle within said channel; (b) a ramp member movable axially within said channel and configured for operative contact with said needle for effecting movement of said needle to a first stage of progression adjacent said opening of said housing and to a second stage of progression wherein at least said proximal puncturing point is out of said housing; and (c) a movable snare member having a portion configured for engagement with said needle for guiding said needle when said needle is out of said housing.
