ABSTRACT
The surface of needles provides reliable information about the extent of its wear. The visualization-based automated needle wear monitoring systems are very important and efficient for unmanned surgical systems. This research work is to use the needle visualization inspection technique to automate the surgical monitoring of needles. A new method based on computer visualization using image processing technique is proposed to estimate the wear and tear of surgical needles in order to identify the time for their replacement. This is possible by using a supervised approach, such that the replacement of needle is carried out before the wear reaches the highest level thereby causing harm. The perimeter of the wear region was described by means of a shape signature, which was normalized and resized to a set of values. These vectors have been classified using SNN algorithm. This algorithm focuses on the appropriate estimation technique in order to replace the surgical needle based on its thickness and depth.
Introduction
Suture selection is dependent on the anatomic site, surgeon's preference and the required suture characteristics. The span, width, and bend of the needle influence the surgeon's ability to place a suture. No standardized sizing system or nomenclature is available for needles or needle holders; the main consideration in the selection of needle is to minimize trauma.
Existing Architecture
By the second half of the 19th century, heavy Silk sutures about the size of current 4-0 or 5-0 caliber were employed to control weakening and for muscle shortening or strengthening. These silk sutures were often waxed at the time of surgery to help ease the passage through tissue. The reusable needles for introducing this suture were large, made of round wire and had an eye to thread the suture. Because of the bulk of these needles compared to the thickness of the sclera, sutures secured the muscle to overlying tendon’s capsule and conjunctiva with the knots tied externally.
Proposed Architecture
A surgical needle is a needle which is used in surgery. Such needles are usually made from stainless steel, because this metal is strong and resists corrosion, and will also bend before breaking, which can be critical when it is being used in a location where breakage might be at risk. Preventing needle breakage is important, as it can be a traumatic experience for the patient when it affects other parts of the body.
SNN Algorithm:
Through prognostic stripes of light having uniform slope and spacing onto the surface of the needle at a foremost firm angle, we can enlighten a worn portion as well as an unworn planar portion. But, the stripes of light on the unworn planar portion that can be viewed from a second angle are straight and uniform.
Extensions
In excess of the past two decades, robotics has revolutionized surgical treatment, and new innovations are ongoing to push the borders of pills. This can be extended so that in future surgeries may be done by machines or robots on human super visualization. Individual error is minimized as the system eliminates false-positive (misguidedly complete count) and reduces false-negatives (the mistaken belief that a mop is missing). what's more we slash along the time and effort that is if not needed for manual including during for each intercession.
Conclusions
In this new-fangled to ballpark figure the wear level in surgical needle is proposed. It is incredible that report of the wear region by means of a signature vector was also used. Sources of fault have to be identified, and the organism has to be evaluated under sensible surgical conditions. This method further more enhances the effectiveness of the needle and also the process by which surgery is safely done for the patients without any side effects and harm. Appropriate method of computing the thickness and depth of a needle used for surgery is used.
