Sieyu Flexible endoscopes: structure and function. The suction, biopsy channel and more


An endoscope is a flexible tube with a lens system on one end and an optical light source at the other. The lens system sends light through the body, allowing doctors to see inside organs or tissues that are otherwise difficult to reach or treat. Endoscopes have many uses, including removing stones from bile ducts as part of an ERCP procedure; exploring foreign bodies (such as gallstones) lodged in the upper GI tract; placing stents into blood vessels near bile duct stones so they can be dislodged by gentle suctioning or percutaneous drainage techniques; performing biopsies on tissue samples collected during an ERCP procedure; and inserting guidewires into the body during laparoscopic surgeries like colonoscopies or laser ablation procedures conducted using robotic systems called da Vinci surgery systems (also known as Da Vinci II robots).”

The air and water channels supply a continual flow of water or air to the lens system for cleaning and keeping the view clear.

The suction and biopsy channel of the flexible endoscope are connected to the lens system, which supplies a continual flow of water or air to the lens system for cleaning and keeping the view clear. The air channel is used in place of a borescope, where it can be inserted into an abnormal structure such as a tumor or abscess. In addition, this channel has been designed specifically for use with our new camera module (for more information see below).

The suction channel can be used to remove blood, saline, or other fluids during the procedure.

This is a very important feature because it allows doctors and nurses to prevent damage from being caused by overinflated balloons.

Other components on this channel include a fiberoptic light source and fiberoptics that carry the light to the tip of the endoscope.

The fiberoptic light source is located inside the suction channel and allows for illumination of areas of interest during the procedure. The fiberoptics carry the light to the tip of the endoscope, where it can be used to illuminate areas of interest without requiring any additional equipment or training on your part.

These are used to illuminate areas of interest during the procedure.

1.Light source: The light source is a fiberoptic light source that can be inserted into a flexible endoscope. It may also be called a fiber-optic illumination system.

2.Fiberoptics: Fiber optics refers to the use of optical fibers (thin strands of glass) for transmitting light signals through space without using wires or other means such as cables or cords. When you look at your computer screen, you see images created using this technology because each pixel on your screen contains thousands of tiny points called pixels—each point is made up by two types of materials: an LED (light emitting diode) and photodiodes which convert photons into electrical signals when they enter them; these electrical signals then travel down wires until they reach an outlet where we plug into our computer!

The mechanical system allows flexing and rotation of the endoscope.

Flexing is bending the endoscope to change the angle of view. Rotating is turning the endoscope to change the angle of view. This is done by a motor that operates a gearbox, which drives two shafts connected by gears.

This is accomplished in different ways depending on whether the instrument is rigid or flexible.

Rigid endoscopes are made of metal, while flexible ones are made of plastic. The main difference between the two types of instruments is how they bend and flex while being used inside the body.

Flexible endoscopes have an outer mechanism that allows them to bend and move easily as they pass through tissue, whereas rigid ones do not have this kind of mechanism and must be bent manually by the user before use (this process can be painful). This ability allows flexible instruments to move more easily through soft tissues like muscle or adipose tissue than rigid instruments which cannot bend easily into these areas due to their construction materials being less malleable than plastics such as polycarbonate which makes up most flexible endoscopes today.

Rigid endoscopes have been around since World War II when surgeons first started using them during operations on soldiers who had lost limbs from battle wounds.

Rigid instruments also tend not only last longer but also cost more money because each part has been designed specifically for its purpose so there’s no need for any replacement parts; thus making these devices easier on patients’ wallets compared with their counterparts from other manufacturers like Olympus Healthcare Group Incorporated whose products need constant maintenance due off-the-shelf replacements every few years due lack durability caused by constant wear over time.

The mechanical system may also be used in some instances to cut tissue or change position of an object within the body.

The suction channel is a flexible tube that connects to a vacuum pump, which supplies negative pressure throughout its length. It has two ports at either end: one for air and one for liquid (Figure 1). When you use this channel, you can aspirate fluids from your patient’s mouth or lungs without touching them directly; this makes it easier than using traditional methods such as needle aspiration with suction cups attached by rubber tubes.

The ERCP elevators are features specific to ERCP systems that allow manipulation of bile duct stones so they can be removed from ducts.

They are inserted through the suction channel and can be used to push bile duct stones out of the duct.

The biopsy channel is also used for removal of tissue samples for further study (biopsy), for injection of dye into ducts for better visualization, and for placement of stents through the wall of ducts into nearby blood vessels.

These procedures typically involve passing a flexible fiberoptic scope through the lumen of a small incision in your mouth or throat that has been made by inserting an endoscopic camera through it. During this procedure, you’ll be asked to swallow some food while holding your breath (this helps keep air from entering into your stomach).

Once inside your body, the scope will connect with other instruments near its tip so they can be used together like Legos® in order to examine internal structures without making any larger incisions than necessary:

Be sure you know if your endoscope has a working biopsy channel before inserting any instruments through it such as a stone elevator or guidewire.

These devices are designed to be inserted into the suction channel, which is located at the tip of most flexible endoscopes, but they can also be used as part of an endoscope’s standard operating procedure (SOP).

In general, there are two types of suction channels: suction and biopsy. The former collects debris from inside your body; whereas the latter collects tissue samples for testing and analysis by pathologists. Both channels work in conjunction with their respective ports within each scope component—the suction port on one side and its corresponding port on the other—to provide access inside your body while advancing through different organs during surgery procedures like laparoscopy or colonoscopy.”

Understanding how an endoscope is made and how it works will help you prevent problems with it.

An endoscope has many components, but it’s mainly made of two parts: the suction channel and the biopsy channel. The suction channel holds the instrument while operating, allowing you to see what’s inside your patient without introducing air into their body cavity. The biopsy channel has a sharp tip that allows doctors to sample tissue samples from inside a patient’s body using just one hand instead of multiple tools like forceps or clamps (which could break off).

Rigid and flexible scopes

The flexibility of our flexible scopes allows us to see more than just the inside of the colon. This allows us to perform very delicate procedures such as prostate biopsies or endoscopic breast cancer treatments, which are difficult using rigid scopes. Traditional telescopes, using the classic two-mirror or lens system, are rigid. They offer good optical quality but are inconvenient to use and can be difficult to control in order to produce good images.
The benefit of flexible scopes is that they allow you to move your telescope around without having to remove it from its mount. This makes it easier for you to view things from different angles and also allows you more freedom when mounting another scope on top of your existing one if desired.

Our flexible scopes use a single flexible tube with a tiny lens on one end (the image) and a small chip on the other (the viewing end). The same tube is used for both image production and viewing. Images are sent directly to the chip.

The flexibility of these scopes allows them to be used in many different environments, including those that would be too dangerous for rigid scopes because they cannot support heavy loads or large lenses.

One of the main advantages of the flexible scope system is that it allows you to view an image in real time while performing a procedure. You can see exactly where your instruments are, what they’re doing, and which tissue they are contacting. This is especially helpful when performing colonoscopies in patients with ulcerative colitis (UC).

Another advantage of this system is that we can perform very delicate rigid endoscopic procedures (such as prostate or bladder biopsies) without risk of injury to the patient. Flexible scopes are ideal for colonoscopies that require more extensive imaging, such as those performed on patients who have had previous colon surgery or who have Crohn’s disease.

In addition, with our flexible scopes we have better control over what we’re doing because we can see what we’re doing at all times. This is especially helpful when performing colonoscopies in patients with ulcerative colitis. With a rigid scope, you would have to rely on your memory of where you were last time and hope that didn’t change too much since then. Flexible scopes allow us to see more than just the inside of the colon; they also let us look into areas like small bowel loops and even lymph nodes without damaging them! We find this very useful during abdominal surgeries such as laparoscopic cholecystectomies (gallbladder removal), esophagectomies (esophagus removal), or gastrointestinal bypass procedures that require additional imaging while still keeping things safe within normal limits.”

Because our flexible scopes allow us to see more than just the inside of the colon, they are also ideal for colonoscopies that require more extensive imaging, such as those performed on patients who have had previous colon surgery or who have Crohn’s disease.

When performing a colonoscopy, patients are typically placed on the table so that their stomach and lower part of their intestines are exposed. This allows us to see more than just the inside of their colon; it also gives us access to areas like the appendix and rectum. However, for some patients who have had previous surgery or who have Crohn’s disease, this position may not be comfortable or safe due to possible complications such as bleeding or obstruction in these areas.
