What Are the Different Reasons for Divestiture?

The process of separating a rubber coating or a rubber layer from a substrate (such as a metal or a cloth) or another rubber layer under an external force. The difference is that the peeling starts from the edge of the interface, and the peeling is the simultaneous force on the entire bonding surface. It can be divided into 180 ° peel and 90 ° peel according to the difference between the tension between the tensile force and the bonding surface during peeling.

Peeling
Dissection is also called anatomical dissection or separation and dissociation. It is an important basic operation for exposing the surgical area to dissect and remove diseased tissues and organs. It should be performed in accordance with normal tissue gaps as much as possible. Peeling can be divided into two types, sharp and blunt, and they are often used clinically in combination.

Peel sharp peel

Refers to anatomical dissection with sharp instruments (usually with a knife or scissors), which must be performed under direct vision, and the action must be accurate and precise. When using a knife, the blade should be sharp, using a pen-style blade method, using the finger's telescoping action (not the wrist or upper limb) to cut, and the blade is cut vertically along the tissue gap for a short distance. When using scissors, you can use a combination of sharp and blunt peeling. The tip of the scissors is used to extend into the tissue space. It should not be too deep. Then open the scissors handle to separate the tissue and carefully distinguish it. If there is no important tissue, cut it. When there are large blood vessels during dissection, they should be clamped or ligated with hemostats and then cut off. Sharp peeling is often used for the peeling of dense tissues such as aponeurosis, sheath, and scar tissue.

Blunt peel

It is mostly used for the dissection of loose tissues such as normal tissue gaps, looser adhesions, benign tumors or extracapsular spaces of cysts, etc. Because there are often no important vascular and nerve tissue structures, sometimes it can be performed under direct vision. Commonly used vascular forceps, closed dissecting scissors, knife handles, strippers (holding small peanut gauze balls, also known as peanut meters with vascular forceps), fingers, and special-purpose strippers (such as film-coat strippers, meninges Stripper) and so on. Finger peeling is one of the commonly used methods in blunt peeling. Blunt peeling is to use the above instruments or fingers to penetrate into the loose tissue space, and gently push the surrounding tissues gradually with an appropriate force. Never rough and barely separate, otherwise it will cause damage or tearing of important tissue structures, causing Adverse consequences.

Notes on peeling operation

1. The surgeon should be familiar with the anatomy and the nature of the lesion. Sharp and blunt peeling should be used in combination according to the situation. When performing anatomic peeling, the relationship between left and right, front and back, and surroundings must be clarified to prevent accidents. Do not easily cut or clamp until the tissue is identified, as it may damage important tissues and organs.
2. The operation should be gentle, precise and accurate, so that some loose adhesions are naturally separated and the anatomical gap is displayed. More attention should be paid to normal anatomical boundaries due to inflammation and other reasons.
