The present invention contemplates a hand-held and hand-operable stitching device capable of securely placing a single interrupted suture through a wound using sterile suturing material with a single squeeze of the device's arms. Operating substantially faster than a surgeon, the compact and lightweight device employs an intuitive stapler-like structure and a center assembly capable of closing a wound with traditional suturing material secured by anchors that remain on either side of the wound. The apparatus employs needle-suture units stored in a center assembly and deployed individually when the device is actuated. When actuated, an epicyclic gear train within a center assembly causes a needle-suture unit to rotate through a circular path through the tissue, bringing the edges of separated tissue together. The suture thread is then secured in its position with anchors and the needle is then disjointed from the suture thread with a blade. 1. A suturing device comprising:a. a driver arm and receiver arm, each comprising a distal end and a proximal end, said driver and receiver arms connected by a hinge at their proximal ends, said hinge being configured to allow said distal ends of said driver arm and said receiver arm to converge and separate through rotation about said hinge while keeping said proximal ends of both arms affixed to each other;b. one or more suture units capable of securing wound tissue housed in a crimped anchor loading system, said suture units comprising a length of suture material having a proximal end and a distal end, a fixed anchor attached to said proximal end of the suture, and a needle attached to the distal end of the suture;c. a center assembly attached to the distal end of the receiver arm and in communication with the driver arm, said center assembly comprising, a suture unit loading system, the crimped anchor loading system, a crimped anchor fastening system, and needle disposing system;d. wherein the driver arm and receiver are ...

In accordance with the present invention there is provided a suturing device. The suturing device includes a length of suture that will be delivered to the site of the PFO and placed through the tissue adjacent the opening to close the PFO. As described in greater detail below, the suture is advanced through the tissue surrounding the opening by a pair of needles that penetrate the tissue adjacent to the opening. A knot is then loosely tied with the length of suture and advanced to the site of the PFO. The tails of the suture extending from the knot are then cut and removed. It is also contemplated that a pre-formed or pre-tied knot may be disposed on the device, wherein after deployment of the suture through the tissue adjacent to the PFO and removal of the device a loop of suture having a pre-tied knot will remain, wherein the pre-tied knot may then be tightened to close the PFO. Further still it is contemplated that other means may be utilized to retain the sutures. For example, it is contemplated that a suture clip or other clip like device may be utilized to retain the suture in a position such that the PFO is closed.

Method of Suturing Tissue

Автор: Chin Wai Ngal, Hasan Jafar Syed, Kobylewski Gary Michael
Принадлежит:

A medical device for installing sutures to close an incision in tissue or human skin is disclosed. The suturing device may provide first and second arcuate needles. Once properly positioned, the first and second arcuate needles are driven through the sub-dermal layer, or alternatively through a superficial surface, of two sections of skin to be joined. This is done in arcuate fashion and at identical and symmetrical rates of angular displacement. In so doing, the sections of skin are pushed toward one another thus assuring horizontal and vertical alignment of the two sections of skin. During the driving or retraction process of the first and second arcuate needles, a suture is positioned within both the first and second sections of skin and transformed from a planar or a multi-planar serpentine orientation to a helical orientation. The resulting suturing process is thus much faster than conventional or manual suturing and results in superior wound approximation/alignment that will lead to decreased scarring compared to prior art devices. 110-.
