Embodiment Construction

[0044] figure 1 An embodiment of a surgical stapling device is shown. The elongated shaft 20 has a proximal end 21, a distal end 22, and a longitudinal axis extending between the proximal end and the distal end. The actuator 10 is connected to the proximal end 21 of the shaft 20 . In this embodiment, the actuator 10 is a manual pistol grip handle; however, a variety of other manual actuators can be used including scissor grip handles, syringe grip handles, endoscope knobs wait. The actuator 10 may also take the form of a robotic interface, such as a DAVINCI disc, a housing including gears or pulleys, a servo mechanism, and the like.

[0045] A circular needle applicator 30 is connected to the distal end 22 of the shaft 20 . Circular needle applicator 30 rotates the arcuate needle along a circular path, thereby enabling the surgeon to selectively apply sutures. Circular needle applicator 30 may be integral with shaft 20 and actuator 10 as an integral disposable instrument ...

Abstract

A surgical suturing device comprises a cartridge having a needle and suture. An elongate shaft has a proximal end and a distal end. An actuator is connected to the proximal end of the elongate shaft. A pair of jaws is connected to the distal end of the elongate shaft. The jaws have a closed position adapted to receive and retain the cartridge, and wherein the jaws are latched in the closed position. The jaws also have a partially opened position adapted to release the cartridge wherein the jaws are biased by a spring from the first opened position towards the closed position. The jaws also have and a fully opened position spaced apart further than the partially opened position, wherein spring does not bias the jaws towards the closed position.

Description

Background technique [0001] The present invention relates generally to surgical devices and procedures, and more particularly to surgical sutures. [0002] Sutures are commonly used in a wide variety of surgical procedures. Manual suturing is usually accomplished by the surgeon by using a pair of fine graspers to grasp and hold the needle, piercing the tissue with the needle, releasing the needle, and then re-grasping the needle to pull the needle and accompanying suture through Tissue to be sutured. Such needles are usually curved with a suture attached to the rear end of the needle. Various automated suturing devices have been attempted to speed up the suturing process and facilitate the thinning of sutures or sutures during endoscopic, laparoscopic or arthroscopic surgery. While automated suturing devices are generally known, no one has previously made or used a surgical suturing device in accordance with the present invention. Description of drawings [0003] While t...
