Embodiment Construction

[0026] For purposes of illustration and not limitation, Figure 1 - Figure 1 1 shows an embodiment of a stapling head 500 for a stapling instrument or other aspects of the stapling instrument.

[0027] Figure 1-Figure 2 A perspective view of this embodiment is shown in plan view and showing hidden features, respectively. As shown, suturing head 500 includes two main housing components 502 and 504 . The housing part 502 defines a portion of a needle track 506 that is complete when the parts 502, 504 are assembled together. This embodiment is similar to the embodiment of Figure 39 described in WO 2008-147555, with certain differences. Clearly, in contrast to the previous embodiment in WO 2008-147555, this embodiment operates by moving the needle 520 through the needle track 506 during the pulling stroke of the thread 530 rather than during the pushing stroke. The distal end 534 of the thread 530 is attached to an engagement mechanism 550 that selectively engages a notch form...

Abstract

An apparatus and method for minimally invasive suturing is disclosed. A suturing device for minimally invasive suturing includes proximal section having a proximal end, a distal end, and a longitudinal axis therebetween; a suture head assembly extending from the distal end of the proximal section; a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis approximately perpendicular to a longitudinal axis of the proximal section, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to and after rotation of the suturing needle; and an actuator extending from the proximal end of the proximal section to actuate a drive mechanism having a needle driver for engaging and rotating the suturing needle.
