Problems solved by technology

The disadvantage of this stapler is that it is difficult to make a stapler tip (tip) of small diameter, because the forming part gives the stapler a considerable radial dimension
The large diameter tip makes many vascular procedures (coronary artery bypass grafting, etc.) virtually impossible to perform with this stapler
Another disadvantage associated with this stapler is that the released staples are not formed into a particularly tight loop compared to manual suturing where the surgeon can pull the knot taut after piercing the tissue with the needle

Embodiment Construction

[0022] figure 1 In it, a fastening device 1 in the form of a stapler is shown comprising a hand piece 2 with a trigger 3 coupled to a drive mechanism 4 which in turn is connected to a An internal staple carrier within an elongated sleeve 5 terminating at a dispensing tip 6 .

[0023] The drive mechanism 4 is housed within the barrel 7 of the handpiece 2 and includes a reciprocating member 8 coupled to the trigger 3 and traveling longitudinally along the barrel 7 in response to the positioning of the trigger 3 . The reciprocating member 8 is connected to a rotating member 9 having a lateral lever 10 extending outside the barrel 7 . After the trigger 3 is initially squeezed, the lever 10 makes the rotating member 9 rotatable, for example by hand actuation etc., so that the entire drive mechanism 4 is rotatable, thereby rotating the carrier relative to the cannula at the dispensing tip 6 . Correspondingly, when the trigger 3 is triggered, the drive mechanism 4 moves to the rig...

Abstract

An apparatus includes a plurality of chambers for receiving an associated plurality of staples, each formed with a shape memory that allows the staple to adopt a straightened configuration, when placed in a stapler, and a deployed configuration for suturing when released from the stapler.

Description

[0001] related application [0002] This application claims priority to Australian Patent Application No. 2007902314, filed 2 May 2007, which application is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to a method and apparatus for fastening, particularly but not exclusively for suturing in medical applications. Background technique [0004] The use of sutures, which may be in the form of a series of threaded stitches, to join tissue together is known in medical applications. These stitches generally require the surgeon to have fairly free access to the suture site to allow the surgeon to manipulate the threading needle. In some cases, hand stitching can be a bit difficult and time consuming. An alternative to suturing is the use of staples that are expelled by the head of a stapler device, passed through the tissue, and then formed by deformation on the opposing anvil of the stapler device are anchored...
