ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a surgical device that will make it much easier for surgeons when performing surgeries to continuously or in an interrupted fashion suture different types of tissues. The present invention is capable of storing a large amount of suture material so suturing will be more or less without interruption, saving time in surgical procedures and cutting the cost of the surgical care.
2. Description of the Prior Art
In the present market there is no suitable suturing device that is capable of performing both suturing and the storing of suture material. The present invention is a needle and a spool, which can be made in different sizes. The invention is made to be relatively inexpensive, pre-sterilized, and disposable.
The prior art includes a variety of needle holders and free needles which are not suitable for use in many surgical procedures, but in the absence of anything better, surgeons are forced to use them, or to use other means of connecting different tissues, such as staplers or clips.
SUMMARY OF THE INVENTION
In accordance with one embodiment of the present invention, the surgical suturing apparatus includes a coil needle that can be made in different lengths, with ½ loops, one loop, or multiple loops. The coil needle is made of hypodermic tubing of different lumen gages to accommodate the passage of different types of suture material. The needle itself represents the distal end of the apparatus that finishes with a sharp tip and an opening that faces the outer radius of the coil.
The proximal end of the needle extends from the axial center of the coil and travels under an angle to fit in the channel define by the conic portion of the shaft where the tip of the conic portion will meet the beginning of the distal end of the needle in the needle's axial center.
The proximal end of the surgical suturing apparatus is a shaft which includes a conic portion in which the needle is secured, and a straight longitudinal portion on which the spool of suture material is placed.
There is a channel in the conic portion of the shaft that travels from the tip of the conus and finishes at the proximal end of the conic portion in such a way that it is under the same angle as the proximal end of the needle and the proximal opening is just above the edge of the distal portion of the spool.
The longitudinal portion of the shaft supports the spool and allows it to freely rotate. The very proximal end of the longitudinal portion is finished in a suitable way so that a surgeon may grasp it.
The spool is made to fit on the longitudinal portion of the shaft and has its own tubular cover to keep the suture material enclosed.
