Problems solved by technology

This is generally undesirable, since the needle typically leaves a larger hole in the subject than is necessary to accommodate only the suture material.
However, this device does not permit sufficient flexibility with regard to the amount of tension that may be applied to the suture and tissue.
Unfortunately, however, such a system does not permit sufficient flexibility in all situations with regard to the appropriate amount of tension to be applied to the subject, since the wire is relatively firm (i.e., firm enough to hold its sets).
Such a system also does not provide sufficient flexibility with regard to the appropriate type of suture stitch to be applied, since the device is specifically configured to provide onl

Embodiment Construction

Overview

[0046] Looking first at FIG. 1, there is shown a suturing instrument 10 which comprises a preferred embodiment of the present invention. Suturing instrument 10 includes a housing 12, a handle 14, a shaft 16 and an end effector 18. Suturing instrument 10 includes a housing 12, a handle 14, a shaft 16 and an end effector 18. Suturing instrument 10 also includes a wire advance button 20, a jaw closing actuator 22, a wire cutting actuator 24, a left-thumb-actuated rotation button 26, and a right-thumb actuated rotation button 28 (FIG. 3). Suturing instrument 10 also includes a wire supply cartridge 30, as well as a shaft retaining nut 32. Shaft retaining nut 32 allows shaft 16 to be dismounted from the remainder of the device for cleaning purposes.

[0047] As will be discussed in further detail below, generally during use, suture wire (comprising wire formed of metal or any other suitable material having the required flexibility and stiffness) is drawn from a winding in wire sup...

Abstract

A device is disclosed for introducing a flexible elongated element through at least two portions of a subject. In an embodiment, the device includes a proximal end and a distal end, as well as an advancement unit for longitudinally advancing the flexible elongated element toward the distal end such that a proximal end of the elongated element may pass from the distal end of said device with sufficient force to pass through the portions of the subject. The device also includes a securing unit for variably adjusting a securing force applied by the flexible elongated element to secure together the portions of the subject.
