Sinuscope (BDJ-001)

Features:
The endoscope has a slender, elongated body, making it easy to maneuver deep into the narrow nasal cavity. Common diameters include 2.7 mm, 3.0 mm, and 4.0 mm. While ensuring sufficient field of view and rigidity, these endoscopes minimize tissue damage and patient discomfort to the greatest extent possible. The 30° endoscope is the most commonly used model. By rotating the endoscope body, surgeons can visualize the lateral structures of the nasal cavity and sinuses, such as the ostia of the frontal sinus, maxillary sinus, and sphenoid-ethmoid recess—making it the workhorse of FESS procedures. The 70° endoscope is used to examine more lateral or recessed areas, such as the deep portions of the frontal sinus and the anterior and posterior walls of the maxillary sinus. Typically equipped with a wide field-of-view angle (e.g., 70°–90°), this endoscope provides surgeons with an expanded visual range, akin to a "wide-angle lens." This enhanced field of view facilitates precise localization and navigation, thereby improving surgical safety.

Accessories:
Waterproof cap: A small rubber or silicone cap fitted onto the connection interface between the sinuscope and the camera.
Camera: The core imaging component that converts the optical image from the sinuscope into an electronic signal. Resolution determines the image clarity.
Light guide: Connects the cold light source to the sinuscope, efficiently transmitting high-brightness cold light to the front end of the scope to illuminate the deep sinus cavities.
Cold-light host: Generates high-brightness, low-heat LED cold light.
Sleeve/Cannula: A hollow metal tube that fits over the outside of the sinuscope. This is a crucial auxiliary component in sinusoscopic surgery.
Irrigation and suction tube: A specialized tube connected to the working channel of the endoscope sheath.
Camera lens wipes: Specialized soft wiping paper.
Sinus surgery suction device: Suction tips of various angles and diameters, used to remove blood, pus, and bone fragments.
Sinus surgical forceps: Includes bite-cutting forceps, polyp forceps, and retraction forceps, used for polyp removal, bone tissue excision, and biopsy sampling.
Minimally invasive cutting power systems (e.g., suction-cutter devices): High-end equipment that integrates suction and cutting functions into one, enabling simultaneous cutting and suction with extremely high efficiency.
Dedicated instrument box/storage box: A box with custom-designed recesses inside, used for storing and transporting sinus endoscopes and sheaths of various angles.
High-temperature, high-pressure sterilization box: a specialized metal box designed to fit into a sterilizer.
