cutting and dissecting instruments
Cutting and dissecting instruments are tools specially designed by medical device manufacturers to help healthcare professionals perform specific operations during surgery. Most cutting and dissecting instruments were made in the early 19th century and are made of durable stainless steel. Some are designed for general use, and some are designed for specific programs. Almost all medical professions can use many surgical instruments. There are precision instruments used in microsurgery, ophthalmology and otology.
Cutting and dissecting instruments-These surgical instruments usually have sharp edges or tips that can cut skin, tissue, and suture human tissue. Surgeons need to cut and dissect tissue to explore irregular growth and remove dangerous or damaged tissue. These instruments have single-edged or double-edged sharp blades or blades. Nurses and doctors need to be very careful to avoid injury, and check these instruments regularly before use in order to re-grind or replace them.
Clamping and Occluding-Many surgical tools are used to compress blood vessels or hollow organs to prevent leakage of their contents. These devices are also used to control bleeding. They are either straight, curved, or angled, and have various internal jaw patterns. Hemostatic forceps and mosquito forceps are some examples of these types of instruments.
Retracting and Exposing-These surgical instruments are used to stop or retract organs and tissues so that the surgeon can enter the surgical area. They unfold skin, ribs, and other tissues; they are also used to separate the edges of surgical incisions. Some retracted and exposed instruments are "self-retaining", which means they will stay open on their own. Other manual styles need to be opened manually.
Grasping and Holding-As the name suggests, these instruments are used to grasp and fix tissues or blood vessels that may be blocked during surgery. Medical assistants must ensure that these instruments are working properly and their locking mechanisms are lubricated to facilitate opening and closing, especially after cleaning and reprocessing. Tweezers are a good example of this type of device.
In addition to these main categories, there are other narrow categories of instruments-such as observation (speculum, endoscope), dilator/probe, suture (needle holder), suction (suction tube), and accessories (mallet, etc.) .
