    FIELD OF THE INVENTION
    This invention relates to a surgical needle used to suture fascial openings that arise during a laparoscopic procedure.
    BACKGROUND OF THE INVENTION
    Laparoscopic surgery uses slim and long instruments. These instruments reach the abdomen by going through the inside of a hollow cylinder device, the so-called trocar. Once the abdominal cavity is inflated with CO 2 gas during laparoscopic surgery, trocars are placed in the abdomen by passing them through layers of the abdominal wall and fascia so that one end is inside the abdomen and the other is outside the abdomen. Trocars have a valve mechanism at one end closer to the abdominal wall. This mechanism prevents gas inside the abdomen from leaking out of the abdomen even when the laparoscopic instruments are placed inside the trocar. The abdominal fascia, which lies beneath the skin and subdermal structures, is the thickest layer of the abdomen. Trocars are last removed after completing a laparoscopic procedure, and the abdominal fascia openings caused by the trocars are then sutured. If the occlusion of the fascial opening fails, this can lead to hernia. Fascia openings could not be sutured efficiently with instruments and needles used to occlude large abdominal wall lesions because the fascia opening has a low-lying position that is likely to become deeper in patients with large subdermal adipose tissue.
    The current state of the art includes surgical needles used in suturing surgically opened fascia openings, and instruments used in suturing fascia openings that arise during a laparoscopic procedure. Surgical needles, although in various forms, are generally round in shape and have the letter " C " similar. A suture is attached to the end of the needle so that the suture follows the needle as it sutures a lesion. Such needles are referred to as atraumatic needles. These needles are the subject of Russian patent documents number RU 2110 964 CI and RU 2074 653 CI. Another type of needle, which has no sewing thread, has an eye through which a sewing thread can be passed so that it follows the needle when sewing a lesion.
    It is difficult to occlude fascial openings caused by trocars with any of these types of needle, as it might not always be possible to penetrate into the lesion, which is similar to a deep well, to turn these needles to such depth, and join the two lips of the fascia opening with the help of these needles.
    The type of needle having an eye at one end through which a suture thread can pass is the subject of Japanese Patent Publication No. JP8243109 and US Patent Document No. 5158543.
    French patent document number FR2732209 (Al), European patent document number EP 1955662, US patent document number US5352219A, Korean patent document number KR20040075834 and International patent application number WO9921489 A1 disclose all needles with ears. These needles could create unnecessary large openings in the fascia because their eye diameters are larger than the diameter of the sutures. In addition, such needles are relatively large instruments that must be manually advanced. To capture the suture, therefore, the surgeon must either join the two lips of the fascia and pass the needle all at once, or guide them through each lip one at a time.
    Various instruments are available that are used to occlude fascia openings, one of which is a double long needle mechanism. The purpose of this mechanism is to pass the suture thread following one of the long and straight needles through the lips of the opening, being tightened with the other needle. However, this mechanism is hardly practicable because the distance between the needles is constant, while the diameter of the opening created in the fascia varies according to the entry angles of the trocars. Therefore, it is not possible for the needles to pierce the lips of the fascia opening at the same distance.
    A complicated mechanism serving to occlude the fascia opening has been described in US Patent Document Number US 2009/0018554 A1. The opening created by the tip of this device in the fascia has a larger diameter than a suture, which makes the use of this instrument in lesions unfavorable.
    Slender and long needles, described in US patent documents number US 006066146A and US 2004/0087978 A1, are guided down through the inside of the abdomen without visualization. These applications involve the risk that the tip of the needle injures intra-abdominal organs, such as the intestine.
    BRIEF DESCRIPTION OF THE INVENTION
    The object of the invention is the construction of a surgical needle having a back part which can be attached and detached during use and which can close the fascia opening practically and reliably.
    DETAILED DESCRIPTION OF THE INVENTION
    The surgical needle designed to achieve the object of this invention is illustrated in the attached figures, in which:
    Figure 1 is a perspective view of the surgical needle according to the invention;
    Figure 2 is a view of the surgical needle of the invention showing all parts separately;
    Figure 3 is a view of the surgical needle of the invention at the moment of piercing the first fascia wall;
    Figure 4 is a view of the surgical needle of the invention after piercing the first fascia wall;
    Figure 5 is a view of one embodiment of the surgical needle of the invention at the moment of piercing the opposing fascia wall;
    Figure 6 is a view of one embodiment of the inventive surgical needle of Figure 5 after drilling through the opposing fascia wall;
    Figure 7 is a view of another embodiment of the surgical needle according to the invention;
    Figure 8 is a view of the embodiment of the surgical needle of Figure 7 according to the invention at the moment the needle and suture pass through the opposing fascia wall;
    Figure 9 is a view of the embodiment of the inventive surgical needle of Figure 7 after the needle and suture have passed through the opposing fascia wall.
    Each part in the figures is numbered as follows: 1. Needle 2. Front 3. Tip 4. Opening 5. Back 6. Sewing thread
    A. fascia
    The surgical needle (1) according to the invention comprises a front part (2) with a sharp tip (3), an opening (4) on the front part (2) near the tip (3), a removable back part (5) located on the back side of the Front part (2) is mounted, and a sewing thread (6) which is embedded in the front part (2) and passes through the inside of the back part (5).
    The front part (2) is a hook-shaped tube with an open and a closed end and its inner diameter just allows the passing of the suture (6). The closed tip (3) is pointed, so that a gentle penetration to the fascia (A) is possible. The sewing thread (6) is embedded in the interior of the front part (2), starting immediately behind the opening (4) at the top (3). The tip (3) of the front part (2) is not in the grip up to the point where the sewing thread (6) is embedded. The back part (5) is attached to the other end of the front part (2). The back part (5) is a hollow cylinder which is slightly larger than the front part (2) with two open ends.
    The open end of the front part (2), which serves as a discharge for the sewing thread (6) is attached to the back part (5). The sewing thread (6) passes through the inside of the front part (2) as well as the back part (5) and lies outside the needle (1). The back piece (5) is removable so that separation and assembly of the front and back pieces (2, 5) is possible whenever desired during the surgical procedure. • «

    The back part (5) is fastened to the front part (2) at the beginning of the use of the needle (1). The needle (1) is guided through a lip of the fascia opening (A) (Figure 3) by means of a needle holder (not shown in the figures). The front part (2) of the needle (1) is passed through a lip of the fascia (A) by pushing it forward with the help of a needle holder, while the back part (5) is not pushed forward, but pulled back by means of a other needle holder is pulled out (Figure 4).
    By the back part (5) of the needle (1), the needle (1) can be detected more easily by means of the needle holder and the front part (2) can more easily pass through the fascia (A). The front part (2), after passing through the fascia (A), is advanced while the back part (5) is retracted, eliminating the difficulty of advancing the back part (5) of the needle (1) to the core of a deep lesion , The back piece (5) could then be attached to the front piece (2), depending on the various surgical strategies. If there is no need for attachment of the back piece (5), sewing can be continued by holding the front part (2) of the needle (1) with a needle holder.
    In one embodiment of the invention, after passing through a lip of the fascia (A), the front part (2) is guided from the bottom to the top of the opposite lip of the fascia (A), thereby forming the seam (Figure 5).
    If the fascia (A) is below a deep and narrow lesion, it may not be possible to guide the needle (1) through the underside of the opposite lip of the fascia (A). In another embodiment of the invention, the sewing thread (6) is cut off behind the front part (2) as soon as the front part (2) has passed through a lip of the fascia (A). The front part (2) and the back part (5) of the needle (1) are joined together and the front part (2) is guided to the underside of the opposite fascia (A) by pushing down on the opposite fascia wall. The sewing thread (6) is guided through the opening (4) at the tip (3) of the front part (2) and fastened to the needle (1) after the front part (2) has been made below the opposite fascia wall (A) ( FIG. 6). The needle (1) is then pulled back over the fascia (A) to pull out the suture (6). Thus, the suture thread (6) is passed through both lips of the fascia opening (A) (Figure 7).
    The fascia opening is practically and reliably closed by the needle (1) of the invention.
    Various applications of the needle (1) according to the invention can be developed. The invention is in principle represented by the claims and should not be limited to the examples described herein.
