A MODIFIED SURGICAL BLADE FOR SHAPE ORIENTED DISSECTION

Abstract

Abstract A surgical blade, or an operating knife, is a standard tool used in hospital for cutting tissue and skin using surgical procedures. It comes in various shapes and forms due to its range of applications. These blades are typically made using carbon steel or stainless steel. With rising healthcare standards, it has become imperative to provide high-quality products. Surgical knives are gamma sterilised, packed, and delivered with utmost efficiency and safety. The Solution provided in this Modified Surgical Blade for Shape Oriented Dissection is the circular, oval, v- shaped, u -shaped and squared blades. This can be attached to an handle portion to facilitate easy usage.

Introduction

A blade is the sharp, cutting portion of a tool, weapon, or machine, specifically designed to puncture, chop, slice, or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are intended to cut.
This includes early examples made from flaked stones like flint or obsidian, evolving through the ages into metal forms like copper, bronze, and iron, and culminating in modem versions made from steel or ceramics. Serving as one of humanity's oldest tools, blades continue to have wide-ranging applications, including in combat, cooking, and various other everyday and specialized tasks.
Blades function by concentrating force at the cutting edge. Design variations, such as serrated edges found on bread knives and saws, serve to enhance this force concentration, adapting blades for specific functions and materials. Blades thus hold a significant place both historically and in contemporary society, reflecting an evolution in material technology and utility.

Background History
It was Morgan Parker who figured a way to put the blade and handle together without a 3rd part In 1915, he received a patent on a new 2- piece scalpel, with blade and handle held together by overlapping metal parts . His new 2-piece design provided rigidity and enabled the exchange of old blades for new after each use. Together with Charles Russell Bard, Parker formed the Bard-Parker Company and developed a method of cold sterilization that would not dull the blades, as did heat. In 1923, Parker bought out Bard's interest consequent to a disagreement over subcontracting manufacture of the scalpel. (Bard-Parker later became a division of Becton, Dickinson and Company.) The present design of the Rib-Back blade was introduced in 1936. Before the development of the Bard-Parker blade, there were over 350 different
kinds of scalpels.

To achieve the desired shape during sectioning of the tissue or object. 2. Easy fixing to the handle portion. 3. To provide all shapes of surgical blades

Summary of the Invention
A simple blade intended for cutting has two faces that meet at an edge. Ideally, this edge would have no roundness but in practice, all edges can be seen to be rounded to some degree under magnification either optically or with an electron microscope.
Force is applied to the blade, either from the handle or pressing on the back of the blade. The handle or back of the blade has a large area compared to the fine edge.
The angle at which the faces meet is important as a larger angle will make for a duller blade while making the edge stronger. A stronger edge is less likely to dull from fracture or have the edge roll out of shape.
The shape of the blade is also important. A thicker blade will be heavier and stronger and stiffer than a thinner one of similar design while also making it experience more drag while slicing or piercing. A filleting knife will be thin enough to be very flexible while a carving knife will be thicker and stiffer; a dagger will be thin so it can pierce, while a camping knife will be thicker so it can be stronger and more durable.
Requirement of the shape during the dissection is very important in diagnosis and treatment of a particular medical or dental problem. The availability of different surgical blade shapes help to fulfill this unattended problem.

Detailed Description
A method and instrument for periodontal surgery performed to repair a patient's gingival defect comprises the steps of making an incision at or near the foramen near the patient's periodontal disease site, inserting the instrument into the incision, Peeling the gingival flap, moving the gingival flap horizontally without widening the incision, raising the interdental papilla within the gingival flap, and expanding the gingival flap to cover the periodontal disease site And pressing the gingival flap to promote fibrin formation. The instrument includes a handle, a first shaft portion extending from the handle, a connection portion, and a blade portion. The connecting portion further has a first end and a second end, the first end is connected to the first shaft at a first angle, and the second end is second to the blade. Connect at an angle of. The blade portion is substantially perpendicular to the plane formed by the handle and the connecting portion.
