Rigid Endoscope Accessories
Rigid endoscopes are made of metal tubes with glass lenses and light channels. They can be used for a variety of medical procedures and are available in a large range of external diameters, from 1 to 12 mm.
Rigid endoscopes require specialized care and maintenance to ensure their performance. Following the manufacturer’s recommendations can prolong the life of these devices and minimize costly repairs.
Autoclavable Trays
Rigid endoscopes are designed to provide a precise and accurate visual image of a surgical site, while also providing flexibility when manipulating the device. They are often connected to manipulation systems that enable surgeons to control the field of view and insertion depth.
These devices typically include a curved, elongated tube with a variety of lenses that provide different angles of view. Some rigid endoscopes can also be equipped with steerable fields of view or integrated zooming options.
While these tools are essential in enabling a wide range of procedures, they can be difficult to clean and maintain. To ensure these instruments are sterile and easy to handle, autoclave the trays that contain them before using them.
Ideally, these trays should be made of a hard material that will not slip around as you use them. This will prevent accidental drops that can be difficult to clean up.
The trays can be used in conjunction with rigid endoscope accessories such as cannula holders and sheath holders. After the trays are cleaned, place them in a disinfectant bath to ensure they are sanitized and then return them to their instrument box.
Some of these trays have 4 grips underneath that help keep them from Rigid Endoscope Accessories sliding as you use them, and if they do slip they won’t be a hazard. This helps reduce the risk of contaminated endoscopes and other equipment.
These trays are made of a polypropylene material that is durable, and can hold a large volume of liquids while being sterilized or autoclaved. They are steam autoclavable at 121oC (250oF), and come in multiple configurations that will work with most robotic liquid handling systems.
These trays are designed to be compatible with all sterilization techniques, including steam and dry autoclaves. They are especially useful for chemists, metallurgists, and others who are involved in high-temperature research.
Cannula Holders
Rigid endoscopes can be used with an array of ancillary equipment accessories. These auxiliary tools allow you to perform additional procedures while also increasing the effectiveness of your endoscope. These accessories can include light sources, air and water sucking pumps, image management systems, and more.
These accessories are particularly useful for surgical procedures, such as laparoscopic and endoscopy surgery. They can improve the efficiency of your operation, provide greater visibility for your patients, and help ensure your safety.
A cannula holder is a type of rigid endoscope accessory that holds a cannula head or tip. These holders are designed for specific cannulas and can be easily installed and removed.
Several different types of cannula holders are available, including Stoelting cannula holders, Kopf cannula holders, and WPI cannula holders. They can be used with a variety of different types of cannulas, including plastics one cannulas and ALZET osmotic pump cannulae.
The cannula holder can be attached to an insertion tube with a universal cord, and the cannula can then be fitted to or removed from the holder. These cannula holders are commonly used with a range of different rigid endoscope accessories, and are a great way to increase the effectiveness of your equipment.
Some cannula holders are transparent, so they can be easily seen by your patients and help you determine whether or not a cannula is stuck in place. This helps avoid a mishap in which the cannula is stuck and prevents injury to your patient.
Another cannula holder is made from a material that traps air bubbles and helps prevent them from becoming airborne and causing harm to the patient. This cannula holder is especially effective when used with a fluid source, such as perfusion or transporter tubes.
These cannula holders are reusable, and they are easy to apply and remove, making them an excellent choice for your medical facility. They attach to tubing using a gentle neobond hydrocolloid that provides long-term attachment and relieves stress on the tubing. The neobond hydrocolloid is non-intrusive and leaves no residue on the skin.
Sheath Holders
A sheath holder is designed to hold an endoscope, allowing for insertion and removal of the endoscope. Sheaths are available in a wide variety of shapes, sizes, and materials to meet the needs of any patient.
Sheaths typically have a first opening at the proximal end and a second opening at the distal end. They may also include one or more crimps that are welded, adhered, soldered, brazed, or a combination thereof to the end of the sheath, or a combination of these methods.
These crimps are designed to keep the endoscope from moving axially towards the distal end and to maintain it a predetermined distance from the distal edge of the sheath. The sheath may also have a plurality of pins, one or more end stops, or a combination of these to secure the endoscope in the sheath.
For example, some sheaths include a pair of dimples at the distal end and a pair of dimples at the proximal end of the sheath to create an annular gap around the endoscope. The sheath also may include a set of tangent lines that tangent with the corresponding dimples on the opposite side of the sheath.
The sheath may also include a second set of dimples that are spaced radially apart and located on a different side of the sheath than the dimples at the distal end. The sheath may further include a set of tangent lines tangent with the corresponding dimples that offset the endoscope within the sheath.
Sheaths can also be molded to the shape of the endoscope, thereby creating a tight fit around the endoscope and keeping it secure. In addition, sheaths can be designed to accommodate a variety of endoscope accessories.
A sheath may also be designed to allow fluids to move across the endoscope, allowing for cleaning and disinfecting of the lens, imaging device, or both. A sheath may also have a pair of dimples on the side of the sheath that are spaced and located radially apart to allow fluids to flow through the sheath during an application cycle.
Instrument Holders
Rigid endoscope accessories, such as cytology brushes (Chapter 8), aspiration tubing, injection/aspiration needles, polypectomy snares, and coagulating electrodes, are often stored in instrument holders. These holders typically include a bracket, a storage tube, and a vapor lid that can be removed for soaking or cleaning the instrument.
When selecting instrument holders, it is important to ensure that the size and shape of the holder is compatible with the scope and accessory being used. If the holder is too large for the endoscope, it may not be able to be used properly. The Rigid Endoscope Accessories holder should also be sturdy enough to prevent injury during storage and transportation.
In addition to being able to hold the holder itself, it is also important to ensure that the endoscope and all its accessories are firmly held in place. This is especially true when using a camera-equipped endoscope, because if the holder becomes loose, the holder and its contents could fall off the endoscope and cause further damage.
There are many different types of holder available, depending on the purpose of the holder and the type of instrument it holds. For example, the DuraHolder(tm) is designed to protect neurosurgical instruments during sterilization. It is made of durable Kimguard Sterilization Wrap(tm) and is the industry standard for instrument holder safety.
Some of these holder designs are specially designed to accommodate both rigid and flexible instrument passage. This allows for a wide variety of instruments to be passed through the scope, including cytology brushes, aspiration tubing, injection/aspiration syringes, coagulating electrodes, and polypectomy snares.
Deflection of the tip of the insertion tube is another feature that can help an endoscopist examine the gastrointestinal tract more thoroughly than with a fixed-view endoscope. Most small-diameter endoscopes have one or two-plane deflection capability, but some larger-diameter endoscopes are equipped with four-way angulation (up/down and left/right) that allow an endoscopist to deflect the tip in any direction by coordinating the movements of the up/down knob and left/right control knobs.
Performing proper disinfection and reprocessing of endoscopes is crucial for maintaining patient safety and healthcare worker safety. This is important because the transmission of infection, such as hepatitis B, from an endoscope can result in serious infections that may lead to the development of serious health problems for the patient. Additionally, opportunistic organisms can be introduced to endoscopic devices that are stored in cabinets after the procedure has ended and could cause sepsis in immunocompromised patients.
