Certain surgical operations require the removal of body parts; consequently other body parts must be reconnected in order to maintain normal body functions. For example, in certain heart operations where bypass surgery is performed, sections of a person's coronary artery to the heart may be either completely replaced or actually bypassed during the heart bypass operation. While some of these arteries are large and can be easily manipulated by a surgeon, other arteries or hollow body organs might be smaller and thus more difficult to manipulate due to their location within the body.
Surgical procedures tend to minimize an incision in a body tissue by utilizing advanced technology medical devices. Consequently, alternative suturing technologies and procedures have to be applied to properly address the growing complexity of intra-body suturing requirements. In the procedure of anastomosis of the urethra and the bladder during radical prostatectomy, for example, with the absence of suitable suturing technologies, the attachment of the urethral stump to the bladder neck is particularly difficult and to date carried out completely manually by the Urology surgeon.
The prior art of manual suturing cannot be applied in these surgical procedures without further abdominal cutting that provides an easier access to the tissues' area. This procedure has significantly high morbidity because of the presence of several large blood vessels in the operating region. It is not uncommon for the needles to slip or tear through these blood vessels and cause significant bleeding. Another disadvantage of the abdominal approach is the risk of punctures to the surgeon's finger; such punctures could lead to transmission of hepatitis, auto-immune deficiency Syndrome (AIDS) and other serious diseases.
Prior art inventions attempt to suture hollow organs include the following:
Amarasinghe, U.S. Pat. No. 4,553,543, disclosed a slotted, partially-flared, cylindrically shaped core mounted inside a tubularly-shaped sleeve with a flared end portion extending out the end of the sleeve. A flexible needle, which is longer than either the core or the sleeve, is held in each of the core slots by the sleeve, but is allowed freedom of longitudinal movement. Threads attached to the needles are inserted through a wall of a tubular body duct by inserting the flared end portion of the core into the body duct and then forcing the needles to move longitudinally in the slots against the flared end portion so that they bend radially outwardly through the walls of the body duct.
Orban III, U.S. Pat. No. 8,177,799, disclosed an apparatus and methods for performing a surgical anastomotic procedure. The apparatus include at least one fastener including a first fastener portion having an anchoring leg portion, a second fastener portion including an anchoring leg portion, wherein the first and second fastener portions are operatively associated with one another to selectively fix the position of the first fastener portion relative to the second fastener portion.
The above mentioned inventions disclose devices and methods for suturing hollow organs, where the actual fastening of the two hollow organs is either manually tied or just fastened by two wirely connected hooks.
